Effects of gender and depression on oral medication adherence in persons with type 2 diabetes mellitus

Background: In a range of chronic conditions including diabetes, it has been observed that depressive symptoms may be associated with nonadherence to medications.Objective: The objective of the study was to determine the main effects, and interactive effect, of depression and gender on patients adherence to oral diabetes medications.Methods: A cross-sectional design was employed, in which persons with type 2 diabetes mellitus completed a questionnaire regarding medication use behaviors, depressive symptoms (measured by the 8-item Patient Health Questionnaire [PHQ-8]), health beliefs, and demographics. A 2 x 2 factorial analysis of variance was used to determine the effects of gender and depression on medication adherence after adjusting for age, education, self efficacy, social support, and number of doses of diabetes medications.Results: Of the 391 respondents who completed the questionnaire, 73 (18.7%) were categorized as having depression (ie, PHQ-8 score >10). Overall, women (n = 196) had a mean (SD) score of 6.10 (6.19) on the PHQ-8, and men (n = 195) had a lower score of 4.62 (5.28) (t = 2.75; P < 0.01). There was a significant main effect of depression, but not gender, on patients' adherence to diabetes medications in that those who were categorized as depressed had significantly worse adherence to diabetes medications (F = 4.82; P = 0.03).Additionally, there was a significant “gender x depression” interaction effect on adherence (F = 5.93; P = 0.01). Men with depression had mean adherence scores that indicated more nonadherence than did men without depression (9.44 [3.45] vs 7.47 [2.50], respectively), but adherence varied little between women with depression and women without depression (7.83 [2.69] vs 7.55 [2.58], respectively).Conclusions: The association between depression and medication adherence appears to be stronger in men than in women. Clinicians should be cognizant of the potential effect of depression on self-care for diabetes, particularly in men with depressive symptoms.     

Peripheral circulatory responses in vivo from regional brachial biceps and lumbar muscles in healthy men and women during pushing and pulling exercise

Background: Although women have been performing increasingly more manual labor in the workplace in the past 2 decades, their physiological responses and gender-based differences in muscle microvascularity during occupational activities have not yet been extensively documented.Objective: This study assessed gender differences and tissue heterogeneity in peripheral circulatory responses from 2 muscle groups during pushing and pulling exercise until volitional exhaustion. Methods: In healthy men and women, near-infrared spectroscopy was used to determine peripheral responses, oxygenation, and blood volume simultaneously from the right biceps brachii and lumbar erector spinae. Pulmonary oxygen uptake was assessed using a metabolic measurement cart.Results: Although the 11 men who participated in the study demonstrated greater pulmonary oxygen uptake and power output at volitional exhaustion, their peak peripheral responses for both muscles were similar to those of the 11 women participating. In both sexes, oxygenations trends decreased in both muscles with an increase in workload. However, whereas blood volume increased in the biceps, it decreased in the lumbar muscle in both sexes. At 20% to 60% levels of peak pulmonary oxygen uptake, the percent change in peripheral bicep responses was greater for men than for women (P < 0.05). In contrast, women demonstrated greater change in lumbar muscle oxygenation compared with men at 40% to 60% of peak pulmonary oxygen uptake (P < 0.05).Conclusions: Similar peripheral responses for biceps and lumbar muscles at the point of volitional exhaustion suggest that gender differences in pulmonary oxygen uptake are independent of oxygen extraction or delivery across the muscle groups monitored. However, at submaximal levels of exercise, the peripheral changes in each muscle were gender dependent. Although biceps and lumbar muscles are 2 discrete muscle groups, based on the heterogeneity found in the blood volume trends it is likely that oxygen supply and demand are regulated by muscle location and muscle fiber characteristics. Overall, gender-based assessment of occupational activities should incorporate both pulmonary and peripheral circulatory responses to understand each sex's performance effectiveness.     

Hospitalizations for HIV/AIDS: Differences between sexes

Background: Women are especially vulnerable to HIV infection because of biological, social, cultural, and economic factors. In Brazil, AIDS was initially seen predominantly in homosexual men, but the epidemic gradually reached a gender balance as increasing numbers of women became infected with HIV.Objective: The aim of the present study was to identify the clinical and epidemiologic characteristics of hospitalized patients with HIV/AIDS of both sexes and compare the differences between them.Methods: This epidemiologic cross-sectional study evaluated gender differences in demographic, social, clinical, and epidemiologic characteristics of patients diagnosed with HIV/AIDS who were admitted for any reason to the Public Hospital of the Medical School of the Federal University of Triângulo Mineiro, Uberaba, Minas Gerais State, Brazil.Results: A total of 363 patients were included in the analysis, with a male/female ratio of 1.1:1.0. Forty-one percent of women were pregnant. Mean age at hospitalization and duration of hospitalization were significantly greater among men (P<0.05). Men and nonpregnant women were admitted because of infection significantly more often than were pregnant women (P<0.05). Significantly more single men who reported homosexual, bisexual, or heterosexual behavior associated with drug use were admitted compared with women (P<0.05). Women admitted for treatment were significantly more likely than men to be employed (P<0.05). Adherence to antiretroviral treatment and T CD4+ lymphocyte count indicated important differences between the sexes, with better parameters observed among nonpregnant and pregnant women compared with men.Conclusions: In the present study, women with HIV/AIDS who were admitted to the hospital for any reason were in better clinical condition compared with men. This observation may be partially explained by the proportion of pregnant women in the study population. These findings suggest that future studies should examine pregnant women with HIV/AIDS as a separate population group to avoid bias in analysis.     

Gender differences in insulin resistance,body composition,and energy balance

Background: Men and women differ substantially in regard to degrees of insulin resistance, body composition, and energy balance. Adipose tissue distribution, in particular the presence of elevated visceral and hepatic adiposity, plays a central role in the development of insulin resistance and obesity-related complications.Objective: This review summarizes published data on gender differences in insulin resistance, body composition, and energy balance, to provide insight into novel gender-specific avenues of research as well as gender-tailored treatments of insulin resistance, visceral adiposity, and obesity.Methods: English-language articles were identified from searches of the PubMed database through November 2008, and by reviewing the references cited in these reports. Searches included combinations of the following terms: gender, sex, insulin resistance, body composition, energy balance, and hepatic adipose tissue.Results: For a given body mass index, men were reported to have more lean mass, women to have higher adiposity. Men were also found to have more visceral and hepatic adipose tissue, whereas women had more peripheral or subcutaneous adipose tissue. These differences, as well as differences in sex hormones and adipokines, may contribute to a more insulin-sensitive environment in women than in men. When normalized to kilograms of lean body mass, men and women had similar resting energy expenditure, but physical energy expenditure was more closely related to percent body fat in men than in women.Conclusion: Greater amounts of visceral and hepatic adipose tissue, in conjunction with the lack of a possible protective effect of estrogen, may be related to higher insulin resistance in men compared with women.     

Gender differences in help-seeking behavior on two internet forums for individuals with self-reported depression

Background: The published literature reflects differences between the sexes in the help-seeking behavior of individuals with depression. Professional mental health services reach men to a lesser extent than women. Internet forums are considered an option to better reach males specifically.Objective: We investigated gender differences in the active use of the Internet to access English- and German-language information on depression.Methods: Analysis differentiated contributors' sex for 200 threads (clusters of responses related to one person seeking advice) followed on 2 Internet forums, www.defeatdepression.org, originating from the United Kingdom, and www.verrueckt.de, originating from Germany. From the qualifying date of January 3, 2007, the investigated threads retrospectively reached 149 days. Using 2 variables, “sex ratio of regular Internet users” and “epidemiologically expected sex ratio,” we calculated a hypothetical value for the female-to-male (F:M) ratio of requests for help of 1.23 for the United Kingdom and 1.16 for Germany. Then we compared the actual versus the estimated gender distributions with a 2-sided x² test.Results: We included 89 queries from www.defeatdepression.org and 97 queries from www.verrueckt.de. On the English-language forum, 46 (52%) of the queries were from women and 43 (48%) from men. On the German-language forum, 67 (69%) of the queries were from women and 30 (31%) from men. The German forum had a significantly higher F:M ratio of contributors compared with the English forum (2.23 vs 1.07, respectively; x² = 5.885; P = 0.015). The actual F:M ratio of contributors for the English forum was similar to the expected calculation (1.07 actual vs 1.23 expected; x² = 0.230; P = 0.652), but was significantly lower than the actual versus the expected F:M ratio of contributors for the German forum (2.23 actual vs 1.16 expected; x² = 4.891; P = 0.027).Conclusion: Possible reasons for the German Internet forum having a higher F:M ratio of contributors compared with the English Internet forum are the differences in presentation style, language, and cultural context between the 2 Web sites.     

Gender-specific differences in bladder cancer: A retrospective analysis

Background: A higher incidence of bladder cancer has been reported in men compared with women. Clinical gender differences have been observed but are less well described.Objective: This retrospective analysis further examines clinical differences in the development and manifestation of bladder cancer between men and women.Methods: Consecutive male and female patients with bladder cancer treated between 1969 and 1997 at a single center (University Hospital of Innsbruck, Innsbruck, Austria) were included in the study. Patient characteristics regarding age, tumor classification, localization, and recurrence were compared between male and female patients. Statistical analysis was conducted using the t test, the χ² test, and the Kaplan-Meier method, with the log-rank test for subgroup analysis.Results: In the 1269 patients (876 men, 393 women) who were examined, 1744 tumors were found. The male-to-female bladder cancer incidence ratio was 2.2:1. Tumors were diagnosed at a significantly younger age in men than in women (mean age: 62 years vs 67 years, respectively; P < 0.001). No difference in the histology of tumors was observed between the sexes. Muscle-invasive tumors more frequently occurred in men than in women (39.8% vs 34.5%; P = NS). In men compared with women, primary tumors were more aggressive (grade 2, 36.6% vs 28.2%; P < 0.001) and tumor recurrences were more invasive (59.0% vs 57.8%; P = NS). Tumors were more often located in the urethra in men than in women (43 [3.4%] vs 9 [1.8%]; P = 0.034), the trigonum (246 [19.8%] vs 75 [14.9%]; P < 0.001), and the bladder dome or vault (128 [10.3%] vs 37 [7.4%]; P = 0.015). Generally, no difference in survival rate was observed between the sexes; only in the subgroup of muscle-invasive tumors (n = 455) did women have a worse overall survival rate than did men (P = 0.022).Conclusions: Clinical gender differences in bladder cancer appear to have a higher incidence in men than in women. In this analysis, women were older at the age of detection, but had less-invasive and less-aggressive tumors than did men. However, women with muscle-invasive disease had a worse overall survival rate than did men in the same subset.     

Women tolerate drug therapy for coronary artery disease as well as men do,but are treated less frequently with aspirin, β-blockers,or statins

Background: Women have worse morbidity, mortality, and health-related quality-of-life outcomes associated with coronary artery disease (CAD) compared with men. This may be related to underutilization of drug therapies, such as aspirin, β-blockers, angiotensin-converting enzyme (ACE) inhibitors, or statins. No studies have sought to describe the relationship of gender with adverse reactions to drug therapy (ADRs) for CAD in clinical practice.Objective: The aim of this study was to determine the prevalence of ADRs associated with common CAD drug therapies in women and men in clinical practice.Methods: In a cohort of consecutive outpatients with CAD, detailed chart abstraction was performed to determine the use of aspirin, β-blocker, ACE inhibitor, and statin therapy, as well as the ADRs reported for these treatments. Baseline clinical characteristics were also determined to identify the independent association of gender with use of standard drug treatments for CAD.Results: Consecutive patients with CAD (153 men, 151 women) were included in the study. Women and men were observed to have a similar prevalence of cardiac risk factors and comorbidities, except that men had significantly higher prevalence of atrial fibrillation (30 [19.6%] men vs 15 [9.9%] women; P = 0.03) and significantly lower mean (SD) high-density lipoprotein cholesterol concentrations (45 [16] mg/dL for men vs 55 [19] mg/dL for women; P < 0.001). No significant differences were observed between the sexes in the prevalence of ADRs; however, significantly fewer women than men were treated with statins (118 [78.1%] vs 139 [90.8%], respectively; P = 0.003). After adjusting for clinical characteristics, women were also found to be less likely than men to receive aspirin (odds ratio [OR] = 0.164; 95% CI, 0.083–0.322; P = 0.001) and β-blockers (OR = 0.184; 95% CI, 0.096-0.351; P = 0.001).Conclusions: Women and men experienced a similar prevalence of ADRs in the treatment of CAD; however, women were significantly less likely to be treated with aspirin, β-blockers, and statins than were their male counterparts. To optimize care for women with CAD, further study is needed to identify the cause of this gender disparity in therapeutic drug use.     

Gender as a determinant of responses to a self-screening questionnaire on anxiety and depression by patients with coronary artery disease

Background: Because patients with coronary artery disease (CAD) could benefit from interventions to decrease psychological distress, it is important to identify these individuals. Both salivary cortisol level and the Hospital Anxiety and Depression Scale (HADS) are recognized measures of stress/anxiety and depression.Objectives: This study was designed to determine whether there is an association between anxiety and depression, as measured by the HADS, and salivary cortisol levels among patients with CAD, and whether this association is affected by gender.Methods: All adult residents of Alberta, Canada, undergoing their first cardiac catheterization for CAD (≥50% occlusion of ≥2 coronary arteries) were eligible for participation in this study. A 14-question survey (the HADS) and 3 saliva-collection devices (a 1-day supply) were sent to the participants' home within 1 week of their initial cardiac catheterization. Participants were asked to take saliva samples for determination of cortisol levels on waking and at 30 and 60 minutes after waking, and then return the completed questionnaire and saliva samples using a prepaid express mailing envelope.Results: Seventy-one adults (52 men and 19 women) participated in the study. Mean (SD) ages were 68.4 (4.6) years for men and 69.1 (4.4) years for women. Among the women, significant negative correlations were found between the HADS anxiety score and the wake-up and 30-minute cortisol levels (higher HADS scores were associated with lower cortisol levels) (all, P < 0.05). Also among women, negative correlations were found between the HADS depression score and the salivary cortisol values, but the differences were not statistically significant. Conversely, among the men, nonsignificant positive correlations were found between the HADS anxiety scores and the salivary cortisol levels (higher HADS scores were associated with higher cortisol levels), and statistically significant positive correlations were observed between the HADS depression scores and all 3 salivary cortisol values (all, P < 0.05).Conclusions: Our findings suggest that the HADS is an appropriate screening instrument for anxiety and depression in patients with CAD. In particular, the scale appears to be sensitive for measuring anxiety in women and depression in men. When the HADS is used clinically as a screening tool, it should be examined through a “gender-based lens.”.     

Gender differences in health-related quality of life among healthy aged and old-aged austrians: Cross-sectional analysis

Background: Although they experience lower mortality rates and lower rates of several chronic diseases than do their male counterparts, aging women are more likely to experience functional impairment in mobility and a general diminished health-related quality of life (HRQoL). The determinants of these gender differences have been the subject of controversy.Objective: This study analyzed gender differences in HRQoL in relation to social and biomedical factors such as age, marital status, educational level, and living arrangements.Methods: Participants were recruited via snowball sampling. All were healthy and lived independently in private homes. Data were obtained from personal interviews, based on a 30-item questionnaire, in the private homes of the participants. Additionally, HRQoL was assessed by means of the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) 26-item questionnaire, which contains 1 general health item, 1 general QoL item, and 24 specific items covering 4 broad domains: physical (DOM I), psychological (DOM II), social (DOM III), and environmental (DOM IV).Results: The participants (98 women, 62 men) enrolled in the study ranged in age from 57 to 95 years (mean [SD] age: 71.8 [8.6] years). The younger age group (aged 57-70 years) comprised 54 women and 25 men, and the older age group (aged >70 years) comprised 44 women and 37 men. Women aged ≤70 years rated their health and QoL significantly higher than did men in the same age group (P = 0.02). These women rated physical capacity (DOM I), social relationships (DOM III), and environment (DOM IV) higher, but not statistically significantly different, than did same-aged men. Women and men exhibited nearly identical psychological health (DOM II) values. Physical capacity (DOM I) differed significantly between women and men aged >70 years (P = 0.03). Women aged >70 years rated their QoL lower than their male counterparts did, although not significantly so. These women depended more on medical treatment, felt significantly less safe in everyday life (P = 0.03), and were less satisfied with themselves.The results of the multiple regression analyses suggest that gender may have a significant impact on general QoL for both age groups (P < 0.01 for the younger age group; P > 0.04 for the older age group). In these analyses, gender also had a significant impact on 2 domains, physical capacity and social relationships (P < 0.02 for both domains), among the participants of the younger age group.Conclusion: Depending on the age group (≤70 vs >70 years) in this small sample of Austrian women and men, gender influenced HRQoL.     

Review of cardiovascular risk factors in women

Background: Although cardiovascular disease (CVD) is the leading cause of death in women in the United States, a knowledge gap persists regarding the mechanisms and management of CVD in women. Before treatment can be optimized, the role of cardiovascular risk factors must be elucidated.Objective: This review provides an updated assessment of cardiovascular risk factors in women, with a focus on cardiometabolic risk.Methods: MEDLINE and Cochrane Library databases, and statistics from the National Health and Nutrition Examination Survey and the American Heart Association, were searched from 1990 to September 2008 using the following terms: cardiovascular risk factors, women, gender, cardiometabolic risk, abdominal obesity, and metabolic syndrome. Publications were classified as English-only original data, reviews, and clinical guidelines. Nonpublished data were excluded. Data were extracted by 2 reviewers independently.Results: Investigators performing multivariable predictive models have estimated that traditional risk factors account for ~70% of the variance in estimating cardiovascular events. However, substantial sex differences exist in the prevalence of traditional risk factors as well as in cardiovascular outcomes. Hypertension is more prevalent in men until the age of 59 years, but then contributes to greater morbidity in older women. Low levels of high-density lipoprotein and elevated triglyceride levels pose more of a threat to women, yet high levels of low-density lipoprotein pose equal risk for women and men. The CVD mortality rate is -3 times greater in people with diabetes than in those without diabetes. Among diabetic individuals, CVD mortality is slightly higher in women compared with men.Conclusions: Increased knowledge of gender-specific risks for CVD has led to national campaigns to educate women. In addition to traditional risk factors, cardiometabolic risk is an important consideration in women. Controversy exists regarding the exact definitions and usefulness of the term metabolic syndrome, but it is clear that the presence of certain factors contributes to increased morbidity and mortality in affected individuals. Abdominal obesity links insulin resistance, dyslipidemia, and hypertension through complex endocrine pathways. Current research is identifying gene × gender interactions, and continued research is necessary to explore the relationship of sex steroids and cardiovascular risk in both men and women.     

Impact of an integrated service system on client outcomes by gender in a national sample of a mentally ill homeless population

Background: Homeless populations with concurrent mental illness have a complex array of service needs that are often addressed in a haphazard or uncoordinated manner. Information is lacking about the effectiveness of programs and public policy in women who are both homeless and mentally ill.Objective: This study assessed the impact of gender on the outcomes of a multisite public policy intervention that implemented components of an integrated service delivery system to address the needs of mentally ill homeless men and women.Methods: A secondary analysis was performed using longitudinal data obtained from homeless men and women in the Access to Community Care and Effective Services and Supports prospective study, which was conducted at 18 sites across the United States. Outcome data from baseline, 3, 12, and 18 months across 5 annual cohorts were analyzed to determine the impact of gender on 6 clinical outcomes, including days of housing, relationships, victimization, social support, alcohol use, and drug use, in homeless men and women with mental illness. The analysis plan included multilevel modeling of longitudinal data.Results: Data were analyzed from a total of 7229 participants, including 4502 men (62%)) (mean age, 38.2 years) and 2727 women (38%) (mean age, 37.2 years). After 18 months of follow-up, women had significantly better outcomes in terms of family relationships (estimated mean score increased 0.100), victimization (score decreased 0.164), and social support (score increased 0.363) than did men (aall, P < 0.001). Being accompanied by children was significantly associated with less change in drug use among women compared with men (P < 0.01). These outcomes were the same across all 18 program sites.Conclusion: Although the addition of services for the homeless in conjunction with clinical and support services offered by case managers had generally positive effects in this study's population, a gender-specific substance abuse treatment intervention should also be included in a comprehensive program for homeless women with mental illness.     

Effect of age and Gender on Fasting and Food-Stimulated Levels of Calcitonin,Parathyroid, and Gastrin Hormones in Healthy Adults

Objective: To investigate the effect of age and gender on basal and food-stimulated serum calcitonin (CT), parathyroid hormone (PTH), and gastrin levels among healthy adults.Methods: Ninety-six healthy adults (76 men and 20 women) aged between 21 and 43 years were recruited. Serum CT, PTH, and gastrin levels were measured after a 9-hour overnight fast, and 1 and 3 hours postprandially.Results: PTH levels decreased early and increased late after feeding. This change was significant in men but not in women. CT levels increased in response to food intake in men but not in women. Gastrin levels were significantly increased after feeding in both men and women. Mean basal and food stimulated CT, PTH, and gastrin levels did not significantly differ between genders. Fasting and post-prandial PTH levels were higher while gastrin levels were lower in older subjects (>30 years old) compared to younger subjects (≤30 years old). Fasting and postprandial CT levels were not significantly different between age groups.Conclusion: Age had a significant effect on fasting and food-stimulated PTH and gastrin hormone levels. The effect of age on PTH levels was independent of baseline vitamin D levels. Men showed significant changes in CT and PTH levels in response to feeding compared to women, although the mean hormone levels were not significantly different between men and women.Abbreviations: CT = calcitonin; MTC = medullary thyroid carcinoma; PTH = parathyroid hormone; SD = standard deviation     

Gender differences in adiponectin and low-grade inflammation among individuals with normal glucose tolerance,prediabetes, and type 2 diabetes

Background: Women with prediabetes and type 2 diabetes mellitus have a higher relative risk of cardiovascular disease than do men. The reason for this is unknown.Objective: We studied the gender differences in adiponectin and in low-grade inflammation, measured by high-sensitivity C-reactive protein (hs-CRP) and interleukin-1 receptor antagonist (IL-1RA), in individuals with normal glucose tolerance, prediabetes, and type 2 diabetes.Methods: In this population-based, cross-sectional study, all individuals born in 1942, 1947, 1952, 1957, and 1962 in Pieksämäki, East Finland, were recruited for participation. A 75-g oral glucose tolerance test and lipid panel were performed, and concentrations of adiponectin, hs-CRP, and IL-1RA were measured. The World Health Organization diagnostic criteria for diabetes and prediabetes (impaired fasting glucose and/or impaired glucose tolerance) were used. Statistical comparisons between men and women were performed by a bootstrap-type ANCOVA.Results: The eligible population included 1294 middle-aged individuals, and of these, 904 (406 men and 498 women) had complete data and were included in the analyses. Absolute adiponectin concentrations were significantly higher in women at all levels of glucose tolerance (normal, prediabetes, and type 2 diabetes), but the gender ratio (women to men) for adiponectin concentrations decreased linearly (P = 0.011) from normal glucose tolerance (1.61; 95% CI, 1.48–1.75) to prediabetes (1.57; 95% CI, 1.36–1.83) and diabetes (1.16; 95% CI, 0.87–1.53). Among participants with normal glucose tolerance, no significant difference was found between the sexes in hs-CRP or IL-1RA. Among patients with prediabetes or diabetes, women had significantly higher concentrations than did men for hs-CRP (for prediabetes, 2.0 vs 1.5 mg/L; ratio, 1.39; 95% CI, 1.04–1.85) and IL-1RA (for prediabetes, 255 vs 178 pg/mL; ratio, 1.43; 95% CI, 1.121.83). The gender ratios (women to men) increased linearly from normal glucose tolerance to prediabetes and type 2 diabetes for both hs-CRP (P = 0.019) and IL-1RA (P = 0.013).Conclusions: Adiponectin concentrations in women decreased relatively more compared with men across individuals with normal glucose tolerance, prediabetes, and type 2 diabetes, whereas inflammatory markers increased relatively more in women. Higher inflammatory stress in women than in men with prediabetes and type 2 diabetes may explain their relatively higher cardiovascular disease risk.     

Gender in atrial fibrillation: Ten years later

Background: Atrial fibrillation (AF) is the most common arrhythmia encountered in both male and female patients.Objective: This evidence-based update attempts to address the advances in the science of AF management in light of key gender issues.Methods: In October 2009, 2 investigators (H.I.M. and B.D.P.) independently searched MEDLINE (PubMed [1950–2009] and Ovid [2000–2009]) for all publication types in the English language, using database-specific controlled vocabulary describing the concepts of AF and gender (atrial fibrillation, gender, women, and men for PubMed; atrial fibrillation and gender for Ovid). The reference sections from the identified publications were also used. The methodologic quality of publications, their content relevance, and the authors' expert opinions guided publication inclusion in this evidence-based narrative review. Articles relevant to gender differences in pathophysiology, outcomes, and treatment of AF are summarized and discussed.Results: Based on current available data, mortality is greater for women with AF than for men with AF. Women with AF have a higher risk of stroke compared with their male counterparts. Women derive the greatest benefit from anticoagulation in AF. There are no significant sex differences in major bleeding risk from warfarin. Women tend to be more symptomatic from AF than are men, but fare worse than men when a rhythm-control strategy is utilized with antiarrhythmic medications. Women have an increased risk for torsades de pointes when taking sotalol or dofetilide, and have a higher risk of bradyarrhythmias when taking antiarrhythmics. AF catheter ablation is successful and beneficial for selected patients of both sexes, although women may incur higher procedural bleeding complications. Women tend to be referred for AF ablation less and later than are men.Conclusions: The past decade has witnessed significant progress in the understanding and management of AF. Awareness of key sex-specific differences in AF allows for a more safe, effective, and personalized approach to the management of this disorder.     

Current issues in the treatment of women with abdominal aortic aneurysm

Background: Abdominal aortic aneurysm (AAA) accounts for ∼45,000 deaths per year in the United States. Despite a striking male predominance of AAA (4:1 male to female), mortality from this disease is almost as high in women (20th leading killer of women and 15th leading killer of men in this country).Objective: The purpose of this review is to highlight the differences in diagnosis, treatment, and treatment outcomes for women with AAA to determine avenues of potential improvement in their care.Methods: Published articles relevant to this review were determined by the experience of the author, by PubMed and MEDLINE searches, and by reviewing the references cited in the reports identified by the first 2 methods. The database searches were performed using the following terms: abdominal aorta, aneurysm, gender, endovascular, and outcomes. Reports were limited to the English language and publication since 1995.Results: Compared with men, women are older when their AAA is diagnosed and treated. Women have higher mortality than do men while undergoing elective open and endovascular repairs, and emergency surgery for ruptured AAAs. Owing to the anatomic complexity of their arterial anatomy, women are less frequently candidates for endovascular repair. Women receive treatment for rupture of AAA less frequently than do men. On Medicare induction, both men and women are eligible for a one-time screening for AAA; however, women qualify for this exam only if they have a family history of AAA.Conclusions: Opportunities to advance the care of women with AAA include improving screening techniques to find AAA prior to rupture and when women are younger and more likely to be candidates for repair. Current clinical practice should focus on decreasing mortality for open surgical repair and developing better endovascular devices so that anatomic obstacles can be overcome and more women can be candidates for this technology. In addition, furthering the understanding of gender differences in the pathophysiology of AAA disease may provide insights into treatments that could prevent the formation of aneurysms.     

Gender Differences in patient-provider symptom agreement in reporting respiratory complaints on a questionnaire

Background: Men and women communicate differently, but it is unclear whether this influences health care outcomes.Objective: Because women patients frequently choose women health care providers, we examined whether this preference was affected by communication styles. We focused on communication of disease-specific symptoms, hypothesizing that symptom agreement between women patients and women health care providers would be greater than between other patient-provider gender combinations.Methods: Patients attending outpatient clinics were recruited as part of a study of respiratory illness at 7 university-affiliated sites during 3 consecutive influenza seasons (2000–2003). Individuals aged ≥ 19 years were offered enrollment if they sought care for cold or flu symptoms at a participating study site. Patients were eligible to participate in the study if they reported any 1 of 6 symptoms: cough, runny nose, fever (subjective), muscle aches, sore throat, and/or exhaustion. Using separate questionnaires, patients and their health care providers recorded the patients' respiratory symptoms (as present or absent). Patients recorded their symptoms before visiting their health care provider, and providers recorded patient symptoms after the visit. Symptom agreement was compared using general estimating equations across all gender combinations.Results: A total of 327 patients (220 women, 107 men) and 84 health care providers (37 women, 47 men) participated in the study. Overall symptom agreement for all patient-provider gender combinations was 81.9% (95% CI, 79.6%–84.2%). For each symptom, the observed agreement significantly exceeded the agreement expected by chance alone (P < 0.001 for all symptoms except “no energy,” which was P = 0.023). The male-male pairing of patient and provider was more likely to agree on a symptom than were the other gender combinations, although not statistically significantly more so than the female-female pairing.Conclusions: In this survey of patients with respiratory illness, there was no significant difference in symptom agreement for most symptoms between the male-male and female-female patient-provider combinations. Based on these findings, symptom agreement alone does not explain why women patients select women health care providers.     

Gender differences in self-rated health,quality of life,quality of care,and metabolic control in patients with diabetes

Background: Because the projected increase in the number of diabetic patients is expected to strain the capabilities of health care providers worldwide, we are challenged to find ways of reducing the burden of diabetes. Maintaining and improving health-related quality of life (QoL) for diabetic patients may be viewed as public health goals.Objective: The aim of this cross-sectional study was to compare different aspects of health, QoL, and quality of care (QoC) between men and women with diabetes as a basis for planning and managing diabees care.Methods: All patients in 2 age groups (aged 20–30 years [younger age group] and aged 50–60 years [middle-aged group]) who were registered with the Department of Endocrinology, Metabolism, and Diabetes at Karolinska University Hospital, Stockholm, Sweden, in October 2004, were recruited for a survey. Questions were included about self-rated health (SRH), QoL, QoC, diabetes-related worries, occupational status, physical activity level, living arrangements, and educational background. Glycosylated hemoglobin (HbA_1c) values were obtained from medical records.Results: Of the 223 eligible patients (109 men, 114 women) in the younger age group, 49 men and 74 women responded to the questionnaire; of the 300 eligible patients (170 men, 130 women) in the middle-aged group, 120 men and 93 women responded. Middle-aged women rated their mental well-being and QoL as worse compared with men (P < 0.001 and P < 0.05, respectively). In both age groups, women reported more diabetes-related worries and less ability to cope (P < 0.05 for the younger age group and P < 0.001 for the middle-aged group for both variables), thus the differences were more marked for middleaged women. Although there were no gender differences in metabolic control, middle-aged women reported less satisfaction with diabetes care (P < 0.001). Higher HbA_1c was related to worse SRH in both men and women when analyzing the age groups together (P < 0.05). This association was most prominent in young women, in whom having more diabetes-related worries was also related to higher HbA_1c (P < 0.01).Conclusion: In this study, women with diabetes appeared to have worse QoL and mental well-being compared with men with diabetes. Therefore, identifying strategies to improve SRH and QoL among diabetic patients, especially among women, is of great importance.
