Previous Delivery of Macrosomia is Associated with Maternal Adiposity in Later Life in Chinese Parous Women with Normal Weight Before and/or After Pregnancy

Objective: Obesity has become a major worldwide health challenge. Macrosomic infants are more likely to experience type 2 diabetes mellitus, obesity and hypertension in adulthood. However, whether macrosomia increases the risk of maternal adiposity later in life is still unknown.Methods: One thousand nine hundred eighty-six unrelated parous women of Chinese Han ancestry aged from 40 to 76 years were enrolled. Self-reported information about reproductive status, including age at menarche, number of children, previous delivery of macrosomic infants, and body weight before and after pregnancy were obtained from personal interview by trained interviewers using a standard questionnaire. Macrosomia was defined as birth weight greater than 4,000 g. Adiposity indexes were measured or calculated.Results: Prior delivery of macrosomia was associated with an increased risk of having obesity in parous women with normal weight before pregnancy (odds ratio [OR] = 1.840; 95% confidence interval [CI] 1.028, 3.294; P = .040), as well as a higher risk of overweight/obesity in parous women with normal weight after pregnancy (OR = 1.777; 95% CI 1.131, 2.794; P = .013). In addition, previous delivery of macrosomia was related with 1.919 (95% CI 1.207, 3.050; P = .006) times higher risk of overweight/obesity in parous women with normal weight before and after pregnancy.Conclusion: The present study suggests that prior delivery of macrosomia may be an independent risk factor for adiposity later in life in parous women with normal weight before and/or after pregnancy.Abbreviations: BMI = body mass index; CI = confidence interval; OR = odds ratio; WC = waist circumference; WHR = waist-to-hip ratio; WHtR = waist-to-height ratio     

Relationship between Smoking and Obesity: A Cross-Sectional Study of 499,504 Middle-Aged Adults in the UK General Population

Background

There is a general perception that smoking protects against weight gain and this may influence commencement and continuation of smoking, especially among young women.

Methods

A cross-sectional study was conducted using baseline data from UK Biobank. Logistic regression analyses were used to explore the association between smoking and obesity; defined as body mass index (BMI) >30kg/m². Smoking was examined in terms of smoking status, amount smoked, duration of smoking and time since quitting and we adjusted for the potential confounding effects of age, sex, socioeconomic deprivation, physical activity, alcohol consumption, hypertension and diabetes.

Results

The study comprised 499,504 adults aged 31 to 69 years. Overall, current smokers were less likely to be obese than never smokers (adjusted OR 0.83 95% CI 0.81-0.86). However, there was no significant association in the youngest sub-group (≤40 years). Former smokers were more likely to be obese than both current smokers (adjusted OR 1.33 95% CI 1.30-1.37) and never smokers (adjusted OR 1.14 95% CI 1.12-1.15). Among smokers, the risk of obesity increased with the amount smoked and former heavy smokers were more likely to be obese than former light smokers (adjusted OR 1.60, 95% 1.56-1.64, p<0.001). Risk of obesity fell with time from quitting. After 30 years, former smokers still had higher risk of obesity than current smokers but the same risk as never smokers.

Conclusion

Beliefs that smoking protects against obesity may be over-simplistic; especially among younger and heavier smokers. Quitting smoking may be associated with temporary weight gain. Therefore, smoking cessation interventions should include weight management support.     

Body size phenotypes and inflammation in the Women's Health Initiative Observational Study

Individuals with "metabolically benign" obesity (obesity unaccompanied by hypertension, dyslipidemia, and diabetes) are not at elevated 10-year risk of cardiovascular disease (CVD) compared to normal weight individuals. It remains unclear whether these obese individuals or normal weight individuals with clustering of cardiometabolic factors display heightened immune activity. Therefore, we characterized levels of acute-phase reactants (C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), white blood cell (WBC) count), adhesion molecules (E-selectin, vascular cell adhesion molecule-1), and coagulation products (fibrinogen, plasminogen activator inhibitor-1 (PAI-1)) among four body size phenotypes (normal weight with 0/1 vs. ≥2 metabolic syndrome components/diabetes and overweight/obesity with 0/1 vs. ≥2 metabolic syndrome components/diabetes) in cross-sectional analyses of 1,889 postmenopausal women from the Women's Health Initiative Observational Study (WHI-OS) nested case-control stroke study. Higher levels of all three inflammatory marker categories were found among women with overweight/obesity or ≥2 metabolic syndrome components or diabetes. Compared to normal weight women with 0 or 1 metabolic syndrome components, normal weight women with ≥2 metabolic syndrome components or diabetes were more likely to have ≥3 inflammatory markers in the top quartile (multivariate odds ratio (OR) 2.0, 95% confidence interval (CI): 1.3-3.0), as were overweight/obese women with 0 or 1 metabolic syndrome components (OR 2.3; 95% CI: 1.5-3.5). Overweight/obese women with ≥2 metabolic syndrome components or diabetes had the highest OR (OR 4.2; 95% CI: 2.9-5.9). Despite findings that metabolically benign obese individuals are not at increased 10-year risk of CVD compared to normal weight individuals, the current results suggest that overweight/obese women without clustering of cardiometabolic risk factors still possess abnormal levels of inflammatory markers.     

Prevalence of breastfeeding in a baby-friendly pediatric practice in Trieste,Italy: follow up to 36 months of age

Preeclampsia is a global health problem and it is the main cause of maternal and perinatal morbidity and mortality. Breastfeeding has been reported to be associated with lower postpartum blood pressure in women with gestational hypertension. However, there is no published data on the role that breastfeeding might play in preventing preeclampsia. The aim of the current study was to investigate if breastfeeding was associated with preeclampsia in parous women. A case-control study was conducted in Saad Abualila Maternity Hospital in Khartoum, Sudan, from May to December 2019. The cases (n = 116) were parous women with preeclampsia. Two consecutive healthy pregnant women served as controls for each case (n = 232). The sociodemographic, medical, and obstetric histories were gathered using a questionnaire. Breastfeeding practices and duration were assessed. A total of 98 (84.5%) women with preeclampsia and 216 (93.1%) women in the control group had breastfed their previous children. The unadjusted odds ratio (OR) of preeclampsia (no breastfeeding vs breastfeeding) was 3.55, 95% confidence interval (CI) 1.64,7.70 and p value = 0.001 based on these numbers. After adjusting for age, parity, education level, occupation, history of preeclampsia, history of miscarriage, body mass index groups the adjusted OR was 3.19, 95% CI 1.49, 6.82 (p value = 0.006). Breastfeeding might reduce the risk for preeclampsia. Further larger studies are required.     

Trends in Cardiovascular Risk Factors by Income Among Japanese Adults Aged 30-49 Years From 2017 to 2020: A Nationwide Longitudinal Cohort Study

ObjectiveIncome is a major social determinant of cardiovascular health. However, individual-level evidence regarding the trends in cardiovascular risk factors by income level among young working-age adults is limited. We thus aimed to examine the trends in cardiovascular risk factors among men and women aged 30-49 years by their income levels.MethodsThis nationwide longitudinal study included Japanese adults aged 30-49 years, who annually participated in the national health screening program from 2017 to 2020. Modified Poisson regression models were used to investigate trends in the prevalence of cardiovascular risk factors (obesity, hypertension, diabetes, and dyslipidemia) according to tertiles of individuals’ annual income, adjusting for potential confounders.ResultsAmong 58 814 adults, 50 024 (85%) were men; the mean (SD) age was 42.1 (5.4) years. Over the study period, the low-income group consistently showed a higher prevalence of obesity, hypertension, and diabetes than the high-income group. The difference in the prevalence of these diseases, particularly hypertension, across income groups increased from 2017 to 2020 among both men (low-income vs high-income: +5.73% [95% CI, 4.72-6.73] in 2017 and +8.26% [95% CI, 7.11-9.41] in 2020) and women (low-income vs high-income: +2.53% [95% CI, 0.99-4.06] in 2017 and +3.83% [95% CI, 1.93-5.73] in 2020).ConclusionAmong adults aged 30-49 years in Japan, a country with a universal healthcare coverage system, we found an increase in the gap of cardiovascular risk factors by income levels over the last 4 years. Careful monitoring of the increasing social disparities is needed to achieve cardiovascular health equity at this life stage.     

The prevalence of pre-hypertension and its association to established cardiovascular risk factors in south of Iran

ABSTRACT: BACKGROUND: Pre-hypertension is associated with an increased risk of the development of hypertension and subsequent cardiovascular disease and raises mortality risk. The aim of this study was to determine the prevalence of pre-hypertension and to explore the associations between pre-hypertension and established cardiovascular risk factors in a population-based sample of Iranian adults. Methods: In this cross-sectional study a representative sample of 892 participants aged [greater than or equal to]30 years was selected using a multistage cluster sampling method. After completion of a detailed demographic and medical questionnaire (gender, age, history of diabetes mellitus and hypertension, taking antihypertensive or hypoglycemic agents and history of smoking), all participants were subjected to physical examination, blood lipid profile, blood glucose, anthropometric and smoking assessments, during the years 2009 and 2010. Variables were considered significant at a p-value [less than or equal to] 0.05. Statistical analysis was performed using SPSS version 11.5 software. RESULTS: Pre-hypertension was observed among 300 (33.7%) subjects, 36.4% for men and 31.4% for women (p > 0.05). The pre-hypertensive group had higher levels of blood glucose and triglycerides, higher body mass index and lower percentage of smoking than did the normotensive group. Multivariate logistic regression analysis showed that obesity and overweight were the strongest predictors of pre-hypertension [odds ratio, 2.74: 95% CI (Confidence Interval), 1.62 to 4.62 p<0.001; odds ratio, 2.56, 95% CI, 1.74 to 3.77, p<0.001 respectively].Conclusions: Overweight and obesity has become important in the association with pre-hypertension in Iranian population. Primary prevention strategies should concentrate on reducing overweight and obesity if the prevalence of pre-hypertension is to be diminished in Iranian adults. Key words: pre-hypertension, cardiovascular risk factor, obesity, BMI.     

Early warning signs of an acute myocardial infarction and their influence on symptoms during the acute phase,with comparisons by gender

Background: Identifying early warning signs of an acute myocardial infarction (AMI) may aid in the early diagnosis of coronary artery disease.Objectives: This study was conducted to assess early warning signs (prodromal symptoms) of AMI, with comparisons made by gender. Another aim was to determine whether these early warning signs had any influence on the patients' acute symptoms of AMI.Methods: This was a multicenter, cross-sectional study of Norwegian patients (aged ≤75 years) hospitalized with their first AMI. A self-administered questionnaire was used to gather information on prodromal symptoms, defined as pain in the chest, pain in the shoulder or back, radiating pain or numbness in the arms, dyspnea, and fatigue. Symptoms were reported for the year before AMI and during the acute stage. Logistic regression analyses were used to examine the association between prodromal symptoms and acute symptoms and the effect of medical history (hypertension, diabetes, and hypercholesterolemia).Results: The self-administered questionnaire had a 72% response rate; the study included 149 women and 384 men diagnosed with first-time AMI. Symptoms occurring during the year before AMI included pain in the chest in 45% (240/533), shoulder or back pain in 51% (270/533), arm pain in 38% (205/533), dyspnea in 33% (176/533), and fatigue in 62% (330/533). There were no statistically significant gender differences. The risk of experiencing chest symptoms in the acute phase was >5 times higher in women who had experienced prodromal symptoms in the chest (adjusted odds ratio [OR] = 5.11; 95% CI, 1.38-18.88) and nearly 3 times higher in men (OR = 2.80; 95% CI, 1.17–6.70). The risk of experiencing shoulder or back pain was almost 5 times higher in men with prodromal shoulder or back pain (OR = 4.96; 95% CI, 3.01–8.19), but no statistically significant association was found in women. The risk of experiencing radiating arm pain or numbness in the acute phase was more than doubled in women with prodromal arm pain (OR = 2.68; 95% CI, 1.19–6.20) and more than tripled in men with prodromal arm pain (OR = 3.11; 95% CI, 1.90–5.07). The risk of experiencing dyspnea in the acute phase was more than doubled in women with prodromal dyspnea (OR = 2.67; 95% CI, 1.25–5.71) and >5 times higher in men with prodromal dyspnea (OR = 5.73; 95% CI, 3.42–9.62). Finally, the risk of fatigue was almost tripled in women (OR = 2.97; 95% CI, 1.28–6.85) and more than doubled in men (OR = 2.51; 95% CI, 1.54–4.11). Hypertensive women, but not men, were less likely to experience chest symptoms in the acute phase (OR = 0.29; 95% CI, 0.10–0.82).Conclusions: Almost half of the study patients (45%) experienced prodromal chest symptoms the year before their first AMI. These prodromal symptoms predicted the symptoms that occurred during the acute stage of AMI, with some differences between the sexes.     

Social and lifestyle factors associated with diabetes in the adult Bahraini population

This paper aimed to assess the prevalence of known diabetes among Bahraini adults, and to determine associated social and lifestyle factors. A community-based survey was carried out on 514 adults aged 30-79 years. The overall prevalence of known diabetes was 9%. Using multivariate analysis, the risk of diabetes was found to be higher among older (50-79 years), female, illiterate, currently married, non-smoking people, those who did not walk regularly, overweight and obese people (BMI > or = 25), those who had a history of hypertension and those who consumed fresh vegetables more than 3 times a week. However, only obesity was found to be significantly associated with diabetes (OR = 1.83, CI 1.48-4.15).     

Association Between Serum Uric Acid Level and Body Mass Index in Sex- and Age-Specific Groups in Southwestern China

Objective: To investigate the sex- and age-specific association between serum uric acid level and body mass index (BMI).Methods: A total of 144,856 subjects aged 20 to 79 years were enrolled in this cross-sectional study. Serum uric acid level, renal function, hepatic function, and lipid profile were investigated.Results: The prevalence of hyperuricemia decreased with age in men but increased in women. In men, the correlation coefficient between the serum urate level and BMI declined steadily with age. Underweight was associated with a 53 to 68% and a 66% lower prevalence of hyperuricemia in men aged 20 to 69 years and in women aged 20 to 29 years, respectively. Overweight and obesity were correlated with a higher odds ratio (OR) (95% confidence interval &lsqb;CI]) for hyperuricemia in both genders. In individuals with overweight or obesity, younger subjects had a higher OR (95% CI) for hyperuricemia than older subjects. Among subjects aged 20 to 59 years, as they gained weight, the OR (95% CI) for hyperuricemia increased faster in women than in men compared with their respective normal-weight controls.Conclusion: Underweight was associated with a lower prevalence of hyperuricemia in men aged ≤69 years. In individuals with overweight or obesity, younger subjects were more likely to develop hyperuricemia than older subjects. With active weight gain, the likelihood for developing hyperuricemia increased faster in women than in men compared with their respective normal-weight controls.Abbreviations: ALT = alanine aminotransferase; AST = aspartate aminotransferase; BMI = body mass index; CI = confidence interval; eGFR = estimated glomerular filtration rate; HDL-C = high-density-lipoprotein cholesterol; LDL-C = low-density-lipoprotein cholesterol; OR = odds ratio     

Cardiometabolic Risk Profiles Associated with Chronic Complications in Overweight and Obese Type 2 Diabetes Patients in South China

Background

Type 2 diabetes is often accompanied by altered cardiometabolic risk profiles, including abdominal obesity, hypertension, and dyslipidaemia. The association of altered cardiometabolic risk profiles with chronic complications of diabetes is not well investigated.

Methods

We recruited 2954 type 2 diabetes patients with a body mass index ≥25 kg/m² who visited the diabetes clinics of 62 hospitals in 21 cities in Guangdong province of China from August 2011 to March 2012. Demographic characteristics, personal and family medical histories, and data on chronic complications of diabetes were collected. Clinical examinations and laboratory assessment were conducted.

Results

Abdominal obesity was found in 91.6% of the study population, elevated blood pressure in 78.3%; elevated serum triacylglycerols in 57.8%, and reduced serum HDL-C in 55.9%. Among the cardiometabolic risk factors, elevated blood pressure was significantly associated with almost all the chronic complications of diabetes. After adjusting for age, gender, duration of diabetes, and HbA1c, elevated blood pressure was significantly associated with diabetic retinopathy (OR 1.63, 95% CI: 1.22–2.19), diabetic nephropathy (OR 3.16, 95% CI: 2.25–4.46), cardiovascular disease (OR 2.71, 95% CI: 1.70–4.32), and stroke (OR 1.90, 95% CI: 1.15–3.12). Abdominal adiposity was significantly associated with diabetic nephropathy (OR 1.39, 95% CI: 1.11–1.74). Elevated triacylglycerols was significantly associated with diabetic retinopathy (OR 1.29, 95% CI: 1.05–1.58) and diabetic nephropathy (OR 1.30, 95% CI: 1.05–1.58). Reduced HDL-C was significantly associated with stroke (OR 1.41, 95% CI: 1.05–1.88).

Conclusions

Altered cardiometabolic risk profiles, and elevated blood pressure in particular, were significantly associated with chronic complications in overweight and obese patients with type 2 diabetes. Future studies on the prevention of chronic complications of diabetes might make lowering blood pressure a primary target.     

Obesity and Lowered Cognitive Performance in a Canadian First Nations Population

The association between obesity, other cardiovascular risk factors, and cognitive function in a Canadian First Nations population was investigated using a cross‐sectional design. Eligible individuals were aged ≥18 years, without a history of stroke, nonpregnant, with First Nations status, and who had undergone cognitive function assessment by the Clock Drawing Test (CDT) and Trail Making Test Parts A and B. Parts A and B were combined into an Executive Function Score (TMT‐exec). Hypertension, a previous history of cardiovascular disease, dyslipidemia, metabolic syndrome, insulin resistance, and the presence and duration of diabetes were examined in addition to obesity. In the case of TMT‐exec only, obese individuals were at an approximately fourfold increased risk for lowered cognitive performance compared to those who were not obese in multivariable models (odds ratio (OR): 3.77, 95% confidence interval (CI): 1.46–9.72) whereas there was no effect for overweight individuals compared to those with a normal weight in unadjusted analysis. Those having an increased waist circumference also had 5 times the risk compared to those without an increased waist circumference (OR: 5.41, 95% CI: 1.83–15.99). Adjusted for age, sex, and insulin resistance, individuals having the metabolic syndrome were at an approximately fourfold increased risk compared to those without the metabolic syndrome (OR: 3.67, 95% CI: 1.34–10.07). No other cardiovascular risk factors were associated. Obesity and metabolic syndrome were associated with lowered cognitive performance. These results highlight the importance of studying the health effects of obesity beyond traditional disease endpoints, even in a relatively youthful population.     

Cumulative incidence of self-reported diabetes in Croatian adult population in relation to socioeconomic status and lifestyle habits

The aim of this study was to determine the 5-year cumulative incidence of self-reported diabetes mellitus in relation to various socioeconomic and lifestyle factors in Croatian adult population. The analysis included 2909 participants of the Croatian Health Cohort Study (CroHort) aged 20-79 years (median 55, interquartile range 43-67; 69% women) with no history of diabetes. There were 163 new cases of diabetes (5-year cumulative incidence 5.6%), without significant differences according to sex. Significant predictors of diabetes were age, body mass index, waist and hip circumference in bivariate logistic regression, and being married or living in partnership (OR = 1.57, 95% CI 1.08-2.28; p = 0.018), body mass index (OR =1.11, 95% CI 1.07-1.14; p < 0.001) and age (OR = 1.02, 95% CI 1.01-1.03; p = 0.004) in multivariate model. Our results indicate that approximately 1% of the Croatian adult population develops diabetes each year. Association of living in partnership with higher diabetes incidence requires further investigation.     

Maternal Age at First Delivery Is Associated with the Risk of Metabolic Syndrome in Postmenopausal Women: From 2008–2010 Korean National Health and Nutrition Examination Survey

BackgroundRecent cross-sectional studies demonstrated that earlier maternal age at first childbirth is correlated with a higher risk of diabetes in postmenopausal women. In this study, we evaluated whether the age at first delivery is associated with the risk of metabolic syndrome (MetS) in postmenopausal women.MethodsA total of 4,261 postmenopausal women aged 45 years or older were analyzed using data generated from Korea National Health and Nutrition Examination Surveys (2008–2010). Subjects were divided into three groups according to the maternal age at first delivery as follows: ≤ 20 years (n=878), 21-25 years (n=2314), and ≥ 26 years (n=1069).ResultsApproximately 37% of subjects had MetS. The prevalence of MetS showed a gradual increase as maternal age at first delivery decreased (≥ 26 years = 30.9% vs. 21-25 years = 39.9% vs. ≤ 20 years = 50.8%, respectively, p < 0.001). Central obesity indices such as trunk fat mass and waist circumference were significantly higher in the group aged ≤ 20 years than other groups. After adjustments for confounding factors, the odds ratios (ORs) for predicting the presence of MetS increased gradually as first delivery age decreased (≥ 26 years vs. 21-25 years vs. ≤ 20 years: OR [95% CI] = 1 vs. 1.324 [1.118-1.567] vs. 1.641 [1.322-2.036], respectively). Among components of MetS, younger maternal age at first delivery (≤ 20 years) was significantly associated with increased waist circumference (OR [95% CI] = 1.735 [1.41-2.13]), elevated blood pressure (1.261 [1.02-1.57]), high triglyceride (1.333 [1.072-1.659]), and low HDL-cholesterol (1.335[1.084-1.643]).ConclusionsOur findings suggest that younger maternal age at first delivery is independently associated with a higher risk of central obesity and MetS in postmenopausal women.     

The ScaI gene polymorphism of the atrial natriuretic factor and essential arterial hypertension in childhood

In order to investigate the contribution of the atrial natriuretic factor (ANF) gene in pathogenesis of essential arterial hypertension (EAH), we analyzed the ScaI gene polymorphism of the ANF gene in a group of children with EAH. Fifty-eight children, aged 8-19 years, with the diagnosis of EAH were included in the association study and were compared to 57 subjects with normal blood pressure (the control group). Arterial hypertension was defined as systolic/diastolic blood pressure higher than the 95th age-gender-height percentile of the adopted reference values. We failed to demonstrate an association between the ScaI ANF gene polymorphism and EAH in childhood (OR = 2; 95% CI 0.9-4.2; p = 0.07), however, we provided evidence of an interaction between the ScaI ANF gene polymorphism and obesity defined as BMI over the 85th percentile (OR = 13.1; 95% CI 1.6-106; p < 0.001).     

The burden of obesity on blood pressure is reduced in older persons: The sardinia study

Introduction:

Being overweight or obese increases the risk of elevated blood pressure. However differences of their effects on blood pressure in different age groups are not clear.

Objective:

The aim of the present study was to evaluate differences of the effects of adiposity on the odds of having hypertension in different age groups.

Design and Methods:

Three thousand fifty‐six subjects (1,532 women and 1,524 men) consist of the drug naïve subjects from the SardiNIA study. Logistic regression models with backward elimination were used to determine and compare the association between categories of obesity on hypertension within young (≤39), middle aged (40–59), and older (60+) subjects. Additional terms controlled for in the model were smoking and alcohol intake status.

Results:

The relationship of body mass index (BMI) on hypertension differed by age, as indicated by the significant interaction term of age with BMI (P <0.01). Older subjects had higher odds of having hypertension than younger subjects but these odds were lower for obese than for lean subjects (OR 10.45, 95% CIs 4.58–23.85 in obese versus OR 33.89, 95% CIs 17.94–64.02 in lean subjects). A similar trend was also observed in middle aged subjects.

Conclusions:

This study shows that among men and women, older age was associated with a lesser effect of BMI on the odds of having hypertension.     

Hypertriglyceridemic waist may explain ethnic differences in hypertension among patients with type 2 diabetes in Sweden

ABSTRACT: BACKGROUND: Hypertension is common among persons with type 2 diabetes. The aim of this study was to analyze the association between ethnicity and hypertension prevalence after adjusting for age, sex, Hba1c, total cholesterol, elevated triglycerides and hypertriglyceridemic waist. The study population consisted of 354 primary health care patients diagnosed with type 2 diabetes (173 Assyrians/Syrians and 181 Swedes) residing in Sodertalje, Sweden. Unconditional logistic regression was used to analyze the data. RESULTS: Hypertension prevalence was higher among Swedes than Assyrians/Syrians, (77% versus 58%; p = 0.001). In the unadjusted logistic regression model, the odds ratio for hypertension in Swedes was twice as high than that in Assyrians/Syrians (OR = 2.44; 95% CI =1.54 - 3.86). In the age- and sex-adjusted model, odds ratio of hypertension was 2.25 (95% CI 1.41-3.60). After adjustments for total cholesterol was made, the odds ratio of hypertension decreased slightly to 1.73. When elevated triglycerides and hypertriglyceridemic waist were separately introduced, the odds ratio of hypertension was no longer significant between the ethnic groups (1.60 and 1.43 for triglycerides and hypertriglyceridemic waist respectively). In addition, advanced age - 60-69 years old (OR = 1.80, CI 95% 1.00-3.20) and [greater than or equal to] 70 years old (OR = 2.88, CI 95% 1.40-5.93), elevated total cholesterol (OR = 1.48, CI 95% 1.12-1.95) and presents of hypertriglyceridemic waist (those with high WC and high TG) were significant confounding factors for the increased risk of hypertension independent of ethnicity. CONCLUSIONS: The crude differences in prevalence of hypertension between the Swedes and Assyrians/Syrians in our study population with type 2 diabetes were no longer significant when adjusting for high triglycerides levels or the presence of hypertriglyceridemic waist.     

Prevalence and determinants of obesity in children in public schools of Sintra, Portugal

Objective: To assess the prevalence of and the factors related to overweight and obesity in a sample of children from the region of Sintra, Portugal. Methods and Procedures: Cross‐sectional study, stratified for freguesia with random selection of schools. Height, weight, triceps skinfold, upper arm and waist circumferences were measured, and overweight/obesity defined according to international criteria. Breast‐feeding, number of daily meals and parents' height and weight data were also collected. Results: One thousand two hundred and twenty‐five children aged 6–10 years were assessed. Overall prevalence of overweight and obesity was 35.6% (23% overweight and 12.6% obesity). Overweight or obese children had higher triceps skinfold, upper arm circumference, arm muscle area, and waist circumference than their normal weight counterparts (P < 0.001). On multivariate analysis, relatively to a child without obese progenitors, a child with one obese progenitor had an obesity risk multiplied by 2.78 (95% confidence interval (CI): 1.76–4.38), while a child with two obese progenitors had a risk multiplied by 6.47 (95% CI: 5.59–16.19). Conversely, being picky was significantly related with a smaller risk of obesity: for boys, odds ratio (OR) = 0.15 (95% CI: 0.04–0.63); for girls, OR = 0.19 (95% CI: 0.06–0.64). Finally, no relationships were found between obesity, birth weight, birth height or breast‐feeding. Discussion: Prevalence of overweight and obesity are elevated among children of the Sintra region in Portugal compared to most other regions of Europe. The relationship with the parents' nutritional state stresses the need to target families for preventing obesity.     

Hypertension and its related factors in Taiwanese elderly people

BACKGROUND: Our study used data collected in Chung-Hsing Village in May 1998 to evaluate the prevalence of hypertension and its correlates in Taiwanese elderly people. METHODS: All of individuals aged 65 and over were recruited as study subjects. A total of 1,093 persons, out of 1,774 registered residents, were contacted by face-to-face interview The response rate was 61.6 percent. However, only 586 respondents had blood tests and completed questionnaires. Analysis in this study was based on these 586 subjects. In order to study the significant correlates of hypertension, the t-test, chi-square analysis, and multivariate logistic regression were used. RESULTS: Our results showed that 66 percent were men and 34 percent were women. The mean age was 73.1 +/- 5.3 years. The proportions of hypertension were 53.09 percent in men and 56.06 percent in women (p > 0.05). After controlling the other covariates, the multivariate logistic regression analysis showed that the significant related factors of hypertension were obesity (OR = 1.88, 95 percent CI = 1.06-3.34, p < 0.05) and renalfunction impairment (OR = 1.69, 95 percent CI = 1.02-2.80, p < 0.05). CONCLUSIONS: The prevalence of hypertension was high in elderly people. Hypertension is significantly associated with obesity and renalfunction impairment in elderly people.     

Epidemiology of type 2 diabetes remission in Scotland in 2019: A cross-sectional population-based study

BackgroundClinical pathways are changing to incorporate support and appropriate follow-up for people to achieve remission of type 2 diabetes, but there is limited understanding of the prevalence of remission in current practice or patient characteristics associated with remission.Methods and findingsWe carried out a cross-sectional study estimating the prevalence of remission of type 2 diabetes in all adults in Scotland aged ≥30 years diagnosed with type 2 diabetes and alive on December 31, 2019. Remission of type 2 diabetes was assessed between January 1, 2019 and December 31, 2019. We defined remission as all HbA1c values <48 mmol/mol in the absence of glucose-lowering therapy (GLT) for a continuous duration of ≥365 days before the date of the last recorded HbA1c in 2019. Multivariable logistic regression in complete and multiply imputed datasets was used to examine characteristics associated with remission. Our cohort consisted of 162,316 individuals, all of whom had at least 1 HbA1c ≥48 mmol/mol (6.5%) at or after diagnosis of diabetes and at least 1 HbA1c recorded in 2019 (78.5% of the eligible population). Over half (56%) of our cohort was aged 65 years or over in 2019, and 64% had had type 2 diabetes for at least 6 years. Our cohort was predominantly of white ethnicity (74%), and ethnicity data were missing for 19% of the cohort. Median body mass index (BMI) at diagnosis was 32.3 kg/m². A total of 7,710 people (4.8% [95% confidence interval [CI] 4.7 to 4.9]) were in remission of type 2 diabetes. Factors associated with remission were older age (odds ratio [OR] 1.48 [95% CI 1.34 to 1.62] P < 0.001) for people aged ≥75 years compared to 45 to 54 year group), HbA1c <48 mmol/mol at diagnosis (OR 1.31 [95% CI 1.24 to 1.39] P < 0.001) compared to 48 to 52 mmol/mol), no previous history of GLT (OR 14.6 [95% CI 13.7 to 15.5] P < 0.001), weight loss from diagnosis to 2019 (OR 4.45 [95% CI 3.89 to 5.10] P < 0.001) for ≥15 kg of weight loss compared to 0 to 4.9 kg weight gain), and previous bariatric surgery (OR 11.9 [95% CI 9.41 to 15.1] P < 0.001). Limitations of the study include the use of a limited subset of possible definitions of remission of type 2 diabetes, missing data, and inability to identify self-funded bariatric surgery.ConclusionsIn this study, we found that 4.8% of people with type 2 diabetes who had at least 1 HbA1c ≥48 mmol/mol (6.5%) after diagnosis of diabetes and had at least 1 HbA1c recorded in 2019 had evidence of type 2 diabetes remission. Guidelines are required for management and follow-up of this group and may differ depending on whether weight loss and remission of diabetes were intentional or unintentional. Our findings can be used to evaluate the impact of future initiatives on the prevalence of type 2 diabetes remission.

Risk factors and outcomes of maternal obesity and excessive weight gain during pregnancy

Objective:

The prevalence of overweight and obesity among women of reproductive age is increasing. We aimed to determine risk factors and maternal, fetal and childhood consequences of maternal obesity and excessive gestational weight gain.

Design and Methods:

The study was embedded in a population‐based prospective cohort study among 6959 mothers and their children. The study was based in Rotterdam, The Netherlands (2001–2005).

Results:

Maternal lower educational level, lower household income, multiparity, and FTO risk allel were associated with an increased risk of maternal obesity, whereas maternal European ethnicity, nulliparity, higher total energy intake, and smoking during pregnancy were associated with an increased risk of excessive gestational weight gain (all p‐values <0.05). As compared to normal weight, maternal obesity was associated with increased risks of gestational hypertension (OR 6.31 (95% CI 4.30, 9.26)), preeclampsia (OR (3.61, (95% CI 2.04, 6.39)), gestational diabetes (OR 6.28 (95%CI 3.01, 13.06)), caesarean delivery (OR 1.91 (95% CI 1.46, 2.50)), delivering large size for gestational age infants (OR 2.97 (95% CI 2.16, 4.08)), and childhood obesity (OR 5.02 (95% CI:2.97, 8.45)). Weaker associations of excessive gestational weight gain with maternal, fetal and childhood outcomes were observed, with the strongest effects for first trimester weight gain.

Conclusions:

Our study shows that maternal obesity and excessive weight gain during pregnancy are associated with socio‐demographic, lifestyle, and genetic factors and with increased risks of adverse maternal, fetal and childhood outcomes. As compared to prepregnancy overweight and obesity, excessive gestational weight gain has a limited influence on adverse pregnancy outcomes.
