Higher prevalence of obesity among children with asthma

The aim of this study is to investigate the association between childhood obesity and asthma, and whether this relationship varies by race/ethnicity. For this population-based, cross-sectional study, measured weight and height, and asthma diagnoses were extracted from electronic medical records of 681,122 patients aged 6-19 years who were enrolled in an integrated health plan 2007-2009. Weight class was assigned based on BMI-for-age. Overall, 18.4% of youth had a history of asthma and 10.9% had current asthma. Adjusted odds of current asthma for overweight, moderately obese, and extremely obese youth relative to those of normal weight were 1.22 (95% confidence interval (CI): 1.20, 1.24), 1.37 (95% CI: 1.34, 1.40), and 1.68 (95% CI: 1.64, 1.73), respectively (P trend < 0.001). Black youth are nearly twice as likely (adjusted odds ratio (OR) = 1.93, 95% CI: 1.89, 1.99), and Hispanic youth are 25% less likely (adjusted OR = 0.75, 95% CI: 0.74, 0.77), to have current asthma than to non-Hispanic white youth. However, the relationship between BMI and asthma was strongest in Hispanic and weakest in black youth. Among youth with asthma, increasing body mass was associated with more frequent ambulatory and emergency department visits, as well as increased inhaled and oral corticosteroid use. In conclusion, overweight, moderate, and extreme obesity are associated with higher odds of asthma in children and adolescents, although the association varies widely with race/ethnicity. Increasing BMI among youth with asthma is associated with higher consumption of corticosteroids and emergency department visits.     

Obesity disparities in preventive care: findings from the National Ambulatory Medical Care Survey, 2005-2007

Obesity and its consequences are a major health concern. There are conflicting reports regarding utilization of preventive health-care services among obese patients. Our objective was to determine whether obese patients receive the same preventive care as normal weight patients. Weighted patient clinic visit data from the National Ambulatory Medical Care Survey (NAMCS) were analyzed for all adult patient visits with height/weight data (N = 866,415,856) from 2005 to 2007. Preventive care practice patterns were compared among different weight groups of normal, obese, and morbidly obese. Obese patients received the least number of preventive exams with a clear gradient present by weight. Obese patients were significantly less likely to receive cancer screening including breast examination (normal weight, reference, obese, odds ratio (OR), 0.8), mammogram (obese OR, 0.7), pap smear (obese OR, 0.7), pelvic exam (obese OR, 0.8), and rectal exam (obese OR, 0.7). The obese population also received less tobacco (obese OR, 0.7) and injury prevention education (obese OR, 0.7), yet significantly more diet, exercise, and weight reduction education. Significant differences in clinic practice patterns relative to normal weight patients were also evident with more physician referral (obese OR, 1.2) and less likely to see physician at the index clinic visit (obese OR, 0.8) and less likely to receive psychotherapy referral (obese OR, 0.6). Significant gaps in preventive care exist for the obese including cancer screening, tobacco cessation and injury prevention counseling, and psychological referral. Although obese patients received more weight-related education, this emphasis may have the consequence of de-emphasizing other needed preventive health measures.     

Youths' perceptions of overweight-related prevention counseling at a primary care visit

Objective: We examined youths’ report of receiving specific overweight‐related preventive counseling and perceived readiness to adopt nutrition and physical activity behaviors recommended by their clinicians. Research Methods and Procedures: We surveyed 324 youth 10 to 18 years old who had a physical exam within the past year. The survey included questions on height, weight, race/ethnicity, mother's education, and topics they discussed with their clinician during their visit. We used multivariable analyses to examine whether weight status and sociodemographic characteristics were predictors of which youth received counseling from their clinicians and which youth were ready to change. Results: The mean (standard deviation) age of participants was 13.7 (1.8) years; 54% were black, and 22% were Hispanic. Less than one‐half of participants reported discussing sugar‐sweetened beverages [38%; 95% confidence interval (CI), 32% to 43%] or television viewing (41%; 95% CI, 36% to 47%) with their clinicians. In multivariable analyses adjusting for participant's age, sex, race/ethnicity, overweight status, and mother's educational attainment, youth whose mothers lacked education beyond high school were significantly less likely to report receiving counseling on any overweight‐specific topic including television viewing [odds ratio (OR), 0.46; 95% CI, 0.27, 0.79], sugar‐sweetened beverage (OR, 0.47; 95% CI, 0.28, 0.80), and fast food consumption (OR, 0.54; 95% CI, 0.32, 0.92). In addition, youth 10 to 14 years old were more likely than those 15 to 18 years old to report they would try to change their television viewing (OR, 4.10; 95% CI, 1.78, 9.44) if recommended by their clinician. Discussion: Youth report infrequently receiving counseling on specific overweight prevention topics during routine primary care visits. Our findings suggest that greater efforts may be needed to reduce social class disparities in overweight prevention counseling and that counseling to prevent overweight in youth may be more acceptable to younger children.     

Insurance status as a modifier of the association between race and stage of prostate cancer diagnosis in Florida during 1995 and 2013

BackgroundCancer stage at diagnosis is a critical prognostic factor regarding a patient’s health outcomes. It has yet to be shown whether insurance status across different race has any implications on the stage of disease at the time of diagnosis. This study aimed to investigate whether insurance status was a modifier of the association between race and stage of previously undetected prostate cancer at the time of diagnosis in Florida between 1995 and 2013.MethodsSecondary data analysis of a cross-sectional survey using information from the Florida Cancer Data System (n = 224,819). Study participants included black and white males diagnosed with prostate cancer in Florida between 1995 and 2013. The main outcome variable was stage of prostate cancer at diagnosis. The main independent variable was race (black vs white). Adjusted logistic regression models were used to explore the association between race, insurance status and stage at diagnosis. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated.ResultsBlack males were more likely to be diagnosed with late stage prostate cancer (OR 1.31; 95% CI 1.27–1.35). Being uninsured (OR 2.28; 95% CI 2.13–2.45) or having Medicaid (OR 1.84; 95% CI 1.70–1.98) was associated with a diagnosis of late stage cancer. Stratified analysis for health insurance revealed that blacks had an increased risk for late stage cancer if uninsured (OR 1.29; 95% CI 1.07–1.55) and if having Medicare (OR 1.39; 95% CI 1.31–1.48).Conclusion: Insurance status may modify the effect of race on late stage prostate cancer in black patients.     

Impact of physician BMI on obesity care and beliefs

Using a national cross-sectional survey of 500 primary care physicians conducted between 9 February and 1 March 2011, the objective of this study was to assess the impact of physician BMI on obesity care, physician self-efficacy, perceptions of role-modeling weight-related health behaviors, and perceptions of patient trust in weight loss advice. We found that physicians with normal BMI were more likely to engage their obese patients in weight loss discussions as compared to overweight/obese physicians (30% vs. 18%, P = 0.010). Physicians with normal BMI had greater confidence in their ability to provide diet (53% vs. 37%, P = 0.002) and exercise counseling (56% vs. 38%, P = 0.001) to their obese patients. A higher percentage of normal BMI physicians believed that overweight/obese patients would be less likely to trust weight loss advice from overweight/obese doctors (80% vs. 69%, P = 0.02). Physicians in the normal BMI category were more likely to believe that physicians should model healthy weight-related behaviors-maintaining a healthy weight (72% vs. 56%, P = 0.002) and exercising regularly (73% vs. 57%, P = 0.001). The probability of a physician recording an obesity diagnosis (93% vs. 7%, P < 0.001) or initiating a weight loss conversation (89% vs. 11%, P ≤ 0.001) with their obese patients was higher when the physicians' perception of the patients' body weight met or exceeded their own personal body weight. These results suggest that more normal weight physicians provided recommended obesity care to their patients and felt confident doing so.     

Racial and ethnic differences in pediatric obesity-prevention counseling: national prevalence of clinician practices

Objective: To assess the frequency of clinician‐reported delivery of obesity‐prevention counseling (OPC) at well‐child visits; evaluating for racial/ethnic discrepancies. Methods and Procedures: Combined, weighted well‐child visit data from the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2001 to 2004 were analyzed for patients aged 4–18 years. Obesity‐prevention counseling was defined as the combined delivery of diet/nutrition and exercise counseling. Patients receiving over‐ or underweight related diagnoses were excluded. Counseling frequencies were calculated. Multivariate logistic regression models examined the relationship of OPC with race, ethnicity, region, provider, sex, age, and payor type. Results: Of 55,695,554 (weighted) visits, 24.4% included OPC (90.8% of these from NAMCS). 15.4% of Hispanic patients received OPC compared to 28.8% of non‐Hispanics. Frequencies were similar between Whites and Blacks (25.0 and 27.1%). Patients with private insurance received more counseling (26.9%) than Medicaid (19.1%) or self‐pay (15.1%). In logistic regression models, non‐Hispanics were more likely to receive OPC (odds ratio (OR) = 1.94; confidence interval (CI) = 1.13–3.32), and patients in the West were less likely to receive OPC (OR = 0.39; CI = 0.18–0.85). Payor type was not predictive in regression analysis. Patients in hospital‐based practices received less OPC (11.9% vs. 25.7% with OR = 0.40; CI =0.22–0.74). Discussion: Obesity prevention, like treatment, is a complex and multifactorial process. With the documented racial and ethnic disparities in rates of pediatric obesity, reasons for discrepancies in the provision of OPC must be further investigated as preventive strategies are formulated.     

A practical approach for implementation of a basal-prandial insulin therapy regimen in patients with type 2 diabetes

Background

Osteopathic philosophy is consistent with an emphasis on primary care and suggests that osteopathic physicians may have distinctive ways of interacting with their patients.

Methods

The National Ambulatory Medical Care Survey (NAMCS) was used to derive national estimates of utilization of osteopathic general and family medicine physicians during 2003 and 2004 and to examine the patient characteristics and physician-patient interactions of these osteopathic physicians. All analyses were performed using complex samples software to appropriately weigh outcomes according to the multistage probability sample design used in NAMCS and multivariate modeling was used to control for potential confounders.

Results and discussion

When weighted according to the multistage probability sample design used, the 6939 patient visits studied represented an estimated 341.4 million patient visits to general and family medicine specialists in the United States, including 64.9 million (19%) visits to osteopathic physicians and 276.5 million (81%) visits to allopathic physicians. Osteopathic physicians were a major source of care in the Northeast (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.42–6.08), providing more than one-third of general and family medicine patient visits in this geographic region. Pediatric and young adult patients (OR, 0.64; 95% CI, 0.45–0.91), Hispanics (OR, 0.63; 95% CI, 0.40–1.00), and non-Black racial minority groups (OR, 0.39; 95% CI, 0.18–0.82) were less likely to visit osteopathic physicians. There were no significant differences between osteopathic and allopathic physicians with regard to the time spent with patients, provision of five common preventive medicine counseling services, or a focus on preventive care during office visits.

Conclusion

Osteopathic physicians are a major source of general and family medicine care in the United States, particularly in the Northeast. However, pediatric and young adult patients, Hispanics, and non-Black racial minorities underutilize osteopathic physicians. There is little evidence to support a distinctive approach to physician-patient interactions among osteopathic physicians in general and family medicine, particularly with regard to time spent with patients and preventive medicine services.     

Racial disparities in treatment and survival from ovarian cancer

BackgroundBlack women with ovarian cancer in the U.S. have lower survival than whites. We aimed to identify factors associated with racial differences in ovarian cancer treatment and overall survival (OS).MethodsWe examined data from 365 white and 95 black ovarian cancer patients from the Hollings Cancer Center Cancer Registry in Charleston, S.C. between 2000 and 2015. We used unconditional logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) between race and receipt of surgery and chemotherapy, and Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% CIs between race and OS. Model variables included diagnosis center, stage, histology, insurance status, smoking, age-adjusted Charlson comorbidity index (AACI) and residual disease. Interactions between race and AACI were assessed using −2 log likelihood tests.ResultsBlacks vs. whites were over two-fold less likely to receive a surgery-chemotherapy sequence (multivariable-adjusted OR 2.46, 95% CI 1.43–4.21), particularly if they had a higher AACI (interaction p = 0.008). In multivariable-adjusted Cox models, black women were at higher risk of death (HR 1.81, 95% CI 1.35–2.43) than whites, even when restricted to patients who received a surgery-chemotherapy sequence (HR 1.79, 95% CI 1.10–2.89) and particularly for those with higher AACI (HR 4.70, 95% CI 2.00 − 11.02, interaction p = 0.01).ConclusionsAmong blacks, higher comorbidity associates with less chance of receiving guideline-based treatment and also modifies OS. Differences in receipt of guideline-based care do not completely explain survival differences between blacks and whites with ovarian cancer. These results highlight opportunities for further research.     

Obesity and Receipt of Clinical Preventive Services in Veterans

Although obese individuals utilize health care at higher rates than their normal weight counterparts, they may be less likely to receive certain preventive services. We conducted a retrospective cohort study of veterans with visits to 136 national Veterans Affairs (VA) outpatient clinics in the United States in the year 2000. The cohort included 1,699,219 patients: 94% men, 48% white, and 76% overweight or obese. Overweight and obese patients had higher adjusted odds of receiving each of the targeted clinical preventive services as recommended over 5 years compared with normal weight patients. The odds for receiving vaccinations increased linearly with BMI category: influenza (men: odds ratio (OR) = 1.13 for overweight to OR = 1.42 for obese class 3; women: OR = 1.15 for overweight to OR = 1.61 for obese class 3) and pneumococcus (men: OR = 1.02 for overweight to OR = 1.15 for obese class 3; women: OR = 1.08 for overweight to OR = 1.28 for obese class 3). The odds for receiving the cancer screening services typically peaked in the mild‐moderately obese categories. The highest OR for prostate cancer screening was in obese class 2 (OR = 1.29); for colorectal cancer, obese class 1 (men: OR = 1.15; women OR = 1.10); for breast cancer screening, obese class 2 (OR = 1.19); and for cervical cancer screening, obese class 2 (OR = 1.06). In a large national sample, obese patients received preventive services at higher, not lower, rates than their normal weight peers. This may be due to the VA health service coverage and performance directives, a more homogeneous patient demographic profile, and/or unmeasured factors related to service receipt.     

The epidemiology and medical management of low back pain during ambulatory medical care visits in the United States

Background

Low back pain (LBP) is a common symptom.

Methods

Patient visits attributed to LBP in the National Ambulatory Medical Care Survey (NAMCS) during 2003–2004 served as the basis for epidemiological analyses (n = 1539). The subset of patient visits in which LBP was the primary reason for seeking care (primary LBP patient visits) served as the basis for medical management analyses (n = 1042). National population estimates were derived using statistical weighting techniques.

Results

There were 61.7 million (SE, 4.0 million) LBP patient visits and 42.4 million (SE, 3.1 million) primary LBP patient visits. Only 55% of LBP patient visits were provided by primary care physicians. Age, geographic region, chronicity of symptoms, injury, type of physician provider, and physician specialty were associated with LBP patient visits. Age, injury, primary care physician status, type of physician provider, and shared physician care were associated with chronicity of LBP care. Osteopathic physicians were more likely than allopathic physicians to provide medical care during LBP patient visits (odds ratio [OR], 2.61; 95% confidence interval [CI], 1.75–3.92) and chronic LBP patient visits (OR, 4.39; 95% CI, 2.47–7.80). Nonsteroidal anti-inflammatory drugs (NSAIDs) and narcotic analgesics were ordered during 14.2 million (SE, 1.2 million) and 10.5 million (SE, 1.1 million) primary LBP patient visits, respectively. Drugs (OR, 0.29; 95% CI, 0.13–0.62) and, specifically, NSAIDs (OR, 0.40; 95% CI, 0.25–0.64) were ordered less often during chronic LBP patient visits compared with acute LBP patient visits. Overall, osteopathic physicians were less likely than allopathic physicians to order NSAIDs for LBP (OR, 0.43; 95% CI, 0.24–0.76). Almost two million surgical procedures were ordered, scheduled, or performed during primary LBP patient visits.

Conclusion

The percentage of LBP visits provided by primary care physicians in the United States remains suboptimal. Medical management of LBP, particularly chronic LBP, appears to over-utilize surgery relative to more conservative measures such as patient counseling, non-narcotic analgesics, and other drug therapies. Osteopathic physicians are more likely to provide LBP care, and less likely to use NSAIDs during such visits, than their allopathic counterparts. In general, LBP medical management does not appear to be in accord with evidence-based guidelines.     

Racial and socio-economic disparities in breast cancer hospitalization outcomes by insurance status

BackgroundBreast cancer remains a major cause of morbidity and mortality among women in the US, and despite numerous studies documenting racial disparities in outcomes, the survival difference between Black and White women diagnosed with breast cancer continues to widen. Few studies have assessed whether observed racial disparities in outcomes vary by insurance type e.g. Medicare/Medicaid versus private insurance. Differences in coverage, availability of networked physicians, or cost-sharing policies may influence choice of treatment and treatment outcomes, even after patients have been hospitalized, effects of which may be differential by race.PurposeThe aim of this analysis was to examine hospitalization outcomes among patients with a primary diagnosis of breast cancer and assess whether differences in outcome exist by insurance status after adjusting for age, race/ethnicity and socio-economic status.MethodsWe obtained data on over 67,000 breast cancer patients with a primary diagnosis of breast cancer for this cross-sectional study from the 2007–2011 Healthcare Cost and Utilization project Nationwide Inpatient Sample (HCUP-NIS), and examined breast cancer surgery type (mastectomy vs. breast conserving surgery or BCS), post-surgical complications and in-hospital mortality. Multivariable regression models were used to compute estimates, odds ratios and 95% confidence intervals.ResultsBlack patients were less likely to receive mastectomies compared with White women (OR: 0.80, 95% CI: 0.71–0.90), regardless of whether they had Medicare/Medicaid or Private insurance. Black patients were also more likely to experience post-surgical complications (OR: 1.41, 95% CI: 1.12–1.78) and higher in-hospital mortality (OR: 1.57, 95%: 1.21–2.03) compared with White patients, associations that were strongest among women with Private insurance. Women residing outside of large metropolitan areas were significantly more likely to receive mastectomies (OR: 1.89, 95% CI: 1.54–2.31) and experience higher in-hospital mortality (OR: 1.74, 95% CI: 1.40–2.16) compared with those in metropolitan areas, regardless of insurance type.ConclusionAmong hospitalized patients with breast cancer, racial differences in hospitalization outcomes existed and worse outcomes were observed among Black women with private insurance. Future studies are needed to determine factors associated with poor outcomes in this group of women, as well as to examine contributors to low BCS adoption in non-metropolitan areas.     

Black and White Women in Maryland Receive Different Treatment for Cervical Cancer

Purpose

Despite an overall decrease in incidence, the death rate from cervical cancer in the United States remains higher in black women than their white counterparts. We examined the Maryland Cancer Registry (MCR) to determine treatment factors that may explain differences in outcomes between races in the state of Maryland.

Methods

Incident cervical cancers in the MCR 1992–2008 were examined. Demographics, tumor characteristics and treatments were compared between races and over time.

Results

Our analysis included 2034 (1301 white, 733 black) patients. Black women were more likely to have locally advanced or metastatic disease at diagnosis (p<0.01). They were more likely to receive any radiation or chemotherapy combined with radiation and less likely to receive surgery (p<0.01). When adjusted for stage and insurance status black women had 1.50 (95% CI 1.20–1.87) times the odds of receiving radiation and 1.43 (95% CI 1.11–1.82) times the odds of receiving chemotherapy. Black women with cervical cancer had 0.51 times the adjusted odds (95% CI 0.41–0.65) of receiving surgery compared to white women. Racial differences in treatment did not change significantly over time.

Conclusions

Surgical treatment for newly diagnosed cervical cancer in the state of Maryland was significantly less common amongst black women than white during our study period. Equivalent treatments are not being administered to white and black patients with cervical cancer in Maryland. Differences in care may contribute to racial disparities in outcomes for women with cervical cancer.     

Maternal Obesity and Breast‐feeding Practices Among White and Black Women

Despite the increase in obesity among women of reproductive ages, few studies have considered maternal obesity as a risk factor for breast‐feeding success. We tested the hypothesis that women who are obese (BMI = 30–34.9) and very obese (BMI ≥35) before pregnancy are less likely to initiate and maintain breast‐feeding than are their normal‐weight counterparts (BMI = 18.5–24.9) among white and black women. Data from 2000 to 2005 South Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) were used. The overall response rate was 71.0%; there were 3,517 white and 2,846 black respondents. Black women were less likely to initiate breast‐feeding and breast‐fed their babies for a shorter duration than white women. Compared to normal‐weight white women, very obese white women were less likely to initiate breast‐feeding (odds ratio: 0.63; 95% confidence interval (CI) = 0.42, 0.94) and more likely to discontinue breast‐feeding within the first 6 months (hazard ratio (HR) = 1.89; 95% CI: 1.39, 2.58). Among black women, prepregnancy BMI was neither associated with breast‐feeding initiation nor with breast‐feeding continuation within the first 6 months. Because very obese white women are less likely to initiate or continue breast‐feeding than other white women, health professionals should be aware that very obese white women need additional breast‐feeding support. Lower rates of breast‐feeding among black women suggest that they should continue to be the focus of the programs and policies aimed at breast‐feeding promotion in the United States.     

Development of Overweight Associated with Childbearing Depends on Smoking Habit: The Coronary Artery Risk Development in Young Adults (CARDIA) Study

Objective: To prospectively evaluate whether childbearing leads to development of overweight in women and to evaluate the role of other known risk factors. Research Methods and Procedures: A prospective, multicenter observational study, the Coronary Artery Risk Development in Young Adults (CARDIA) Study from 1986 to 1996, examined subjects at baseline and in follow‐up years 2, 5, 7, and 10. Included were 998 (328 black and 670 white) nulliparous women, age 18‐30 years, who were not overweight at baseline. Relative odds for incident overweight (BMI ≥ 25 kg/m²) associated with parity change (0, 1, or 2+) and risk factors were estimated using discrete‐time survival models adjusted for baseline and time‐dependent covariates. Results: Parity change‐association with development of overweight depended on smoking habit (interaction, p < 0.001). In multivariate adjusted models, 1 and 2+ births vs. 0, respectively, were associated with increased risk for development of overweight among never smokers [odds ratio (OR) = 2.66; 95% confidence interval (CI): 1.80, 3.93, and 2.10, 95% CI: 1.24, 3.56] and decreased risk among current smokers (OR = 0.41; 95% CI: 0.17, 0.96, and 0.36, 95% CI: 0.08, 1.65). Risk was increased for black vs. white race (OR = 3.49; 95% CI: 2.59, 4.69), frequent weight cycling (OR = 1.45; 95% CI: 1.03, 2.04), and high school education or less (OR = 2.21; 95% CI: 1.50, 3.26) and was decreased for highest physical activity quartile (OR = 0.62; 95% CI: 0.43, 0.90). Discussion: Childbearing contributes to development of overweight in nonsmokers but not in smokers, where development of overweight is less likely in women who bear children. Race, education, and behaviors are important factors in development of overweight in young women.     

Energy-Related Indicators and Breast Cancer Risk among White and Black Women

Energy-related indicators, including physical activity, energy intake, body mass index (BMI) and adult weight change, have been linked to breast cancer risk. Very few studies of these associations have been conducted among black women, therefore we used the Nashville Breast Health Study (NBHS) to determine whether similar effects were seen in black and white women. The NBHS is a population-based case-control study of breast cancer among women age 25 to 75 years conducted between 2001 and 2010 in and around the Nashville Metropolitan area. Telephone interviews and self-administered food frequency questionnaires were completed with 2,614 incident breast cancer cases ascertained through hospitals and the statewide cancer registry, and 2,306 controls selected using random digit dialing. Among premenopausal white and black women, there was little effect of adult exercise or other energy-related indicators on breast cancer risk, regardless of tumor estrogen receptor (ER) status. The beneficial effect of adult exercise on postmenopausal breast cancer appeared to be comparable between white and black women (highest tertile relative to none - white odds ratio [OR] 0.8, 95% confidence interval [CI] 0.6-1.0, p for trend=0.05; black OR 0.7, 95% CI 0.4-1.1, p for trend=0.07); however, among black women the reduction was limited to those with ER-positive disease. White and black women should be encouraged to engage in more physical activity to reduce their risk of postmenopausal breast cancer.     

Pediatricians’ Own Weight: Self‐perception,Misclassification, and Ease of Counseling

Objectives: Pediatricians underdiagnose overweight and feel ineffective at counseling. Given the relationship between physicians’ health and health habits and counseling behaviors, we sought to determine the 1) percentage of pediatricians who are overweight; 2) accuracy of pediatricians’ own weight status classification; and 3) relationship between weight self‐perception and perceived ease of obesity counseling. Research Methods and Procedures: This study was a cross‐sectional, mail survey of North Carolina pediatricians that queried about their weight status and ease of counseling. Accuracy of pediatricians’ self‐classification of weight status was compared with BMIs derived from self‐reported height and weight. Using logistic regression, controlling for potential confounding variables, we examined the association between weight perception and ease of counseling. Results: The unadjusted response rate was 62%, and the adjusted response rate was 71% (n = 355). Nearly one‐half (49%) of overweight pediatricians did not identify themselves as such. Men had greater adjusted odds of misclassifying overweight than women [odds ratio (OR), 3.61; 95% confidence interval (CI) = 1.81, 7.21]. Self‐classified “thin” pediatricians had nearly six times the odds of reporting more counseling difficulty as a result of their weight than “average” weight pediatricians (OR = 5.69; 95% CI = 2.30, 14.1), and self‐identified “overweight” pediatricians reported nearly four times as great counseling difficulty as “average” weight physicians (OR = 3.84; 95% CI = 1.11, 13.3), after adjustment for self‐reported BMI weight status and other potential confounders. Discussion: The roles that physician weight misclassification and self‐perception potentially play in influencing rates of obesity counseling warrant further research.     

Race, childhood insulin, childhood caloric intake, and class 3 obesity at age 24: 14-year prospective study of schoolgirls

The prevalence of Class 3 obesity (BMI ≥40 kg/m²) has more than doubled in the past 25 years. In a 14‐year prospective study from age 10 to 24 of a biracial schoolgirl cohort (293 black, 256 white), we assessed childhood correlates of Class 3 BMI at age 24. Of 42 girls with Class 3 BMI at age 24, 36 (86%) were black. By logistic regression, significant explanatory variables of Class 3 BMI at age 24 included top decile waist circumference at age 11 (odds ratio (OR) 5.7, 95% confidence interval (CI) 2.3–13.9, P = 0.0002), age 10 BMI ≥ the Center for Disease Control (CDC) 2000 top 15% (OR 7.0, 95% CI 2.5–19.3, P = 0.0002), and a three‐way interaction between race, childhood insulin, and average caloric intake from age 10 to age 19 (for each unit increase, OR 1.7 95% CI 1.3–2.2, P = 0.0003). Age 10 BMI, age 11 waist circumference, and interaction of race, childhood insulin, and childhood caloric intake predict Class 3 obesity in young adulthood, facilitating childhood identification of girls at high risk for developing Class 3 obesity.     

Racial/Ethnic Differences in Weight Perception

The objective of this research was to estimate the prevalence of weight misperception among adults using the most recent nationally representative data, according to measured weight category and to assess the relationship between weight misperception and race/ethnicity. Height and weight were measured as part of the 1999–2006 National Health and Nutrition Examination Survey. The study sample consisted of 17,270 adults aged ≥20 years. BMI was categorized as underweight (BMI < 18.5), healthy weight (18.5 ≤ BMI < 25), overweight (25 ≤ BMI < 30), and obese (BMI ≥ 30). Subjects reported self‐perception of weight status. Among study subjects, 31.7% of healthy weight adults, 38.1% of overweight adults, and 8.1% of obese adults incorrectly perceived their weight category. Among obese men, the odds of weight misperception were higher for non‐Hispanic blacks (odds ratio (OR) = 3.0; 95% confidence interval (CI) = 2.0–4.5) compared to non‐Hispanic whites and for persons with less than a high school education (OR = 2.1; 95% CI = 1.3–2.1), compared to those with some college education. Among obese women, the odds of weight misperception were higher for non‐Hispanic blacks (OR = 3.4; 95% CI = 1.4, 3.1) and Mexican Americans (OR = 1.9; 95% CI = 1.2, 3.2) compared to non‐Hispanic whites and for persons with less than high school education compared to those with some college education (OR = 5.5; 95% CI = 3.3–9.3). Weight misperception is highly prevalent in the US population, and more frequent in racial/ethnic minorities, males, and in persons with lower educational levels. Addressing the issue of weight misperception may help address the problem of obesity in the United States by increasing awareness of healthy weight levels, which may subsequently have an impact on weight‐related behavior change.     

The association of obesity and cervical cancer screening: a systematic review and meta-analysis

Obese women are at an increased risk of death from cervical cancer, but the explanation for this is unknown. Through our systematic review, we sought to determine whether obesity is associated with cervical cancer screening and whether this association differs by race. We identified original articles evaluating the relationship between body weight and Papanicolaou (Pap) testing in the United States through electronic (PubMed, CINAHL, and the Cochrane Library) and manual searching. We excluded studies in special populations or those not written in English. Two reviewers sequentially extracted study data and independently extracted quality using standardized forms. A total of 4,132 citations yielded 11 relevant studies. Ten studies suggested an inverse association between obesity and cervical cancer screening. Compared to women with a normal BMI, the combined odds ratios (95% CI) for Pap testing were 0.91 (0.80-1.03), 0.81 (0.70-0.93), 0.75 (0.64-0.88), and 0.62 (0.55-0.69) for the overweight and class I, class II, and class III obesity categories, respectively. Three out of four studies that presented the results by race found this held true for white women, but no study found this for black women. In conclusion, obese women are less likely to report being screened for cervical cancer than their lean counterparts, and this does not hold true for black women. Less screening may partly explain the higher cervical cancer mortality seen in obese white women.     

Relationship of BMI,Waist Circumference,and Weight Change with Use of Health Services by Older Adults

Objective: To examine the relationship of BMI, waist circumference (WC), and weight change with use of health care services by older adults. Research Methods and Procedures: This was a prospective cohort study conducted from 2001 to 2003 among 2919 persons representative of the non‐institutionalized Spanish population ≥60 years of age. Analyses were performed using logistic regression, with adjustment for age, educational level, size of place of residence, tobacco use, alcohol consumption, and presence of chronic disease. Results: Obesity (BMI ≥ 30 kg/m²) and abdominal obesity (WC >102 cm in men and >88 cm in women) in 2001 were associated with greater use of certain health care services among men and women in the period 2001–2003. Compared with women with WC ≤ 88 cm, women with abdominal obesity were more likely to visit primary care physicians [odds ratio (OR): 1.36; 95% confidence limit (CL): 1.06–1.73] and receive influenza vaccination (OR: 1.30; 95% CL: 1.03–1.63). Weight gain was not associated with greater health service use by either sex, regardless of baseline BMI. Weight loss was associated with greater health service use by obese and non‐obese subjects of both sexes. In comparison with those who reported no important weight change, non‐obese women who lost weight were more likely to visit hospital specialists (OR: 1.45; 95% CL: 1.02–2.06), receive home medical visits (OR: 1.61; 95% CL: 1.06–2.45), be hospitalized (OR: 1.88; 95% CL: 1.29–2.74), and have more than one hospital admission (OR: 2.31; 95% CL: 1.19–4.47). Discussion: Obesity and weight loss are associated with greater health service use among the elderly.
