Abstract
BACKGROUND AND AIMS Diabetes and/or hypertension are the most common conditions in older people, and also related to higher cardiovascular disease (CVD) incidence and mortality. This study aims to explore the risk of CVD incidence and mortality among older people with diabetes and/or hypertension over a 16 years follow-up period and investigates the role of depression and obesity in these relationships. METHODS 6,855 participants aged 50+ from the English Longitudinal Study of Ageing (ELSA). The main exposure is having diabetes and/or hypertension at baseline (2002/2003) compared to not having, but excluded those with coronary heart disease (CHD) and/or stroke (CVD). Survival models are used for CVD incidence and mortality up to 2018, adjusted for socio-demographic, health, health behaviours, cognitive function, and physical function characteristics. RESULTS 39.3% of people at baseline had diabetes and/or hypertension. The risk of CVD incidence was 1.7 (95%CI: 1.5; 1.9) higher among people with diabetes and/or hypertension compared to those without and was independent of covariates adjustment. People with diabetes and/or hypertension were also 1.3 (95%CI: 1.1; 1.8) times more likely to die from CVD than those without. We did not find evidence for an elevated risk of CVD incidence and mortality among people with obesity nor among those with depression. CONCLUSIONS In order to effectively reduce the risk of CVD incidence and mortality among older people, treatment as well as management of hypertension and diabetes should be routinely considered for older people with diabetes and/or hypertension.

Abstract
BACKGROUND The prevalence of obesity, hypertension and diabetes is increasing. Hypertension and diabetes are common complications. Additionally, obesity and hypertension-diabetes comorbidity (HDC) are both closely related to insulin resistance. The aim of this study was to determine the association of obesity indicators with HDC in elderly individuals. METHODS This retrospective cohort study included 74,955 subjects aged ≥ 60 years living in Xinzheng, Henan Province, from January 2011 to December 2019. The data were collected from the annual health examination dataset. Cox proportional hazard regression models and competing-risk survival regression models were used to examine the relationships between the three indicators and HDC risk. RESULTS After 346,504 person-years of follow-up, HDC developed in 9,647 subjects. After further adjustments for confounders and death competing risks, compared with a body mass index (BMI) of 18.5-23.9 kg/m2, the fully adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of BMI < 18.5, 24-27.9 and ≥ 28 kg/m2 for HDC morbidity were 0.651(0.538,0.788),1.00,1.396(1.336,1.459) and 1.769(1.666,1.878), respectively. Moreover, participants with abdominal obesity measured via waist circumference (WC) or waist-to-height ratio (WtHR) had a higher risk of HDC (HR:1.513; 95% CI: 1.45,1.578 and HR:1.412;95% CI: 1.353,1.473), respectively, than participants with low WC or with low WtHR. In the joint analyses, the highest risk was observed in participants who were overweight and who had central obesity (HR: 1.721; 95% CI: 1.635, 1.811) compared with the nonoverweight and noncentral obesity groups. CONCLUSIONS Increased BMI, WC and WtHR were associated with an increased risk of HDC. There was an additive interaction between general body adiposity (as measured via BMI) and central obesity (as measured via WC and WtHR) for HDC. Therefore, reasonable control of BMI, WC and WtHR may be an effective measure to prevent HDC among elderly individuals.

Abstract
OBJECTIVE To identify the relationship between obesity indicators and hypertension-diabetes comorbidity (HDC) among adults in central China. DESIGN AND SETTING A cross-sectional study was conducted from 1 June 2015 to 30 September 2018 in 11 districts of Hubei Province, China. PARTICIPANTS A total of 29 396 participants aged 18 years or above were enrolled in the study. 2083 subjects with missing data were excluded. Eventually, 25 356 participants were available for the present analysis. MAIN OUTCOME MEASURES Data were subjected to univariable and multivariable logistic regression to examine the association between obesity indicators (body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR)) and HDC prevalence. Crude odds ratio and adjusted OR (AOR) with associated 95% CI were calculated. RESULTS Overall, 2.8% of the respondents had HDC. The odds of HDC prevalence increased with the BMI of the participants (18.5≤BMI (kg/m2)≤23.9-1; 24≤BMI (kg/m2)≤26.9-AOR: 5.66, 95% CI: 4.25 to 7.55; BMI (kg/m2)≥27-AOR: 7.96, 95% CI: 5.83 to 10.87). The risk of HDC also increased with the WHtR of participants (WHtR≤P25-1; P25≤WHtR≤P50-AOR: 1.73, 95% CI: 1.10 to 2.71; P50 ≤WHtR≤P75-AOR: 2.51, 95% CI: 1.60 to 3.92; WHtR≥P75-AOR: 3.22, 95% CI: 2.01 to 5.16). Stratified analysis by gender showed that high BMI and WHtR were risk factors of HDC in males and females. However, the odds of HDC prevalence increased only when WHtR≥P75 in males, whereas the probability of HDC increased when WHtR≥ P25 in females. CONCLUSION High BMI and WHtR can increase the risk of HDC among Chinese adults. Reasonable control of BMI and WHtR may be beneficial in preventing HDC. Females should focus on maintaining an optimal WHtR earlier.

Abstract
In view of the epidemic proportions of obesity in South Africa and its relationship to cardiometabolic diseases, such as hypertension, a cross sectional study was conducted to investigate the utility of obesity indicators for predicting hypertension among older persons (≥60 years, n = 350) in the Limpopo Province of South Africa. The WHO STEPwise approach was used to collect data on demographic and lifestyle factors. Anthropometrics and blood pressure were measured according to the standard procedures. Receiver operating characteristic curves (ROC) were used to investigate and compare the ability of obesity indicators to predict overall hypertension and either increased systolic (SBP) or increased diastolic (DBP) blood pressure. The area under the ROC curve (AUC) was used to assess a certain indicator’s potential to predict overall hypertension and either increased SBP or increased DBP. Multivariate logistic regression analysis was used to determine the relationship of hypertension with obesity indicators. The mean age of the participants was 69 years (±SD = 7), and hypertension (46%), general obesity (36%) and abdominal obesity (57%) were prevalent among older persons. The obesity indicator body mass index (BMI) (AUC = 0.603 (0.52; 0.69)) was the best predictor of hypertension in older men. Waist circumference (WC) (AUC = 0.640 (0.56; 0.72)) and waist-to-height ratio (WHtR) (AUC = 0.605 (0.52; 0.69)) were better predictors of hypertension than BMI and waist-to-hip ratio (WHR) in older women. After adjustment for risk factors, only WC (AOR = 1.22 (1.16; 1.79)) was significantly associated with hypertension in older women, proposing WC as a screening tool for the prediction of hypertension in South African older women.

Abstract
Objective The objective is to determine the prevalence of comorbid hypertension and blood pressure (BP) control among patients with Type-2-diabetes-mellitus attending a tertiary-hospital in Lagos, and identify the determinants of poor BP control. Materials and Methods A cross-sectional study of 238 consecutive patients with Type-2-diabetes Mellitus (DM) at the adult diabetes-clinic of a tertiary health-facility in Lagos, Nigeria over a 5-month period. Data were retrieved with the aid of structured-investigator-administered-questionnaire, physical examination, and review of hospital record. Hypertension was defined as BP ≥140/90 mmHg and target BP control was defined as <130/80 mmHg. Logistic regression analysis was used to identify the independent determinants of poor BP control. Results Comorbid hypertension was present in 187 (78.6%) of study participants with males (68/87 [78.8%]) and females (119/151 [78.2%]) similarly affected, P = 0.907. Older age (62.9 ± 10.1 vs. 54.9 ± 9.6 years) and obesity (35.3% vs. 17.6%) were associated with comorbid hypertension, P < 0.05. Awareness, treatment, and medication adherence rates were 96.3%, 100%, and 46%, respectively. Only 17.1% (n = 32/187) had BP controlled to target. Waist circumference (WC) (adjusted odd ratio: 1.04, 95% confidence interval [CI]: 1.01-1.06) and poor glycemic control (adjusted odd ratio: 5.39, 95% CI: 2.07-13.99) were the predictors of poor BP control. Conclusion The prevalence of co-morbid hypertension in Type 2 DM patients in our setting is high and the BP control rate is low. Increasing WC and poor glycemic control are the independent determinants of poor BP control. Individualized weight reduction and glycemic control strategies may help achieve target BP control.

Abstract
BACKGROUND Hypertension is the leading cause of cardiovascular disease morbidity and mortality worldwide. Its struggle involves knowing its prevalence. Insufficient data on hypertension in adults in Lubumbashi, Democratic Republic of Congo (DRC), prompted the conduct of this study. The objectives were to determine the prevalence of hypertension and to identify the associated factors in adults in Lubumbashi. Methodology. A cross-sectional study was carried out among 6,708 adults from October 15th to November 24th, 2018, in Lubumbashi. Anthropometric data, lifestyle, and medical history were collected. Hypertension was defined when the mean of the last two blood pressure (BP) measurements was greater than or equal for systolic (SBP) at 140 mmHg and for diastolic (DBP) at 90 mmHg or a history of taking antihypertensive medication whatever the value of the BP. Logistic regression was used to identify the relative effects of hypertension risk factors and all statistical tests were declared significant at a p value <0.05. RESULTS The female participants numbered 4479 (66.8%). The mean age of all participants was 47.9 ± 16.5 years. The mean SBP and DBP were 128.4 ± 25.9 mmHg and 79.1 ± 15.3 mmHg, respectively. The overall prevalence of hypertension was 33.6%. This prevalence was statistically higher in women than in men (34.5% vs. 31.7%; p=0.024). After logistic regression, the risk of hypertension increased with age >50 years (aOR = 5.85 [5.19-6.60]), overweight (aOR = 1.25 [1.11-1.41]), obesity (aOR = 1.25 [1.11-1.41]), central obesity (aOR = 1.37 [1.16-1.61]), diabetes mellitus (aOR = 2.19 [1.63-2.95]), alcohol consumption (aOR = 1.21 [1.05-1.39]), nonconsumption of vegetables (aOR = 1.35 [1.02-1.80]), and history of stroke (aOR = 2.57 [1.88-3.51]). Hypertension was inversely associated with being underweight (aOR = 0.68 [0.53-0.87]). CONCLUSION The prevalence of hypertension in the city of Lubumbashi is high as in other cities of the DRC and Africa. This situation requires the implementation of prevention, detection, and treatment programs for hypertension.

Abstract
Adverse cardiovascular outcomes are linked to higher burden of obesity and hypertension. We conducted a secondary analysis of data for 5135 participants aged ≥ 16 years from our community-based hypertension prevalence study to determine the prevalence of obesity and association between multiple anthropometric indices and blood pressure (BP). The indices were waist circumference (WC), body mass index (BMI), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), a body shape index(ABSI), abdominal volume index (AVI), body adiposity index (BAI), body roundness index (BRI), visceral adiposity index (VAI) and conicity index (CI). We performed statistical analyses to determine the association, predictive ability, cutoff values and independent determinants of hypertension. Crude prevalence of obesity was 136 per 1000 (95% confidence interval 126-146). BMI had the strongest correlation with systolic and diastolic BP (rs = 0.260 and 0.264, respectively). Indices of central adiposity (AVI, WC, WHtR, BRI) were the strongest predictors of hypertension (≥ 140/90 mmHg), and their cut-off values were generally higher in females than males. WHR, age, BMI and CI were independent determinants of hypertension ≥ 140 mmHg (p < 0.05). We conclude that, based on this novel study, measures of central adiposity are the strongest predictors and independent determinants of hypertension in our population, and cut-off values vary from previously recommended standards.

Abstract
OBJECTIVE We aimed to estimate the gender-specific prevalence and associated factors of hypertension among elderly people in Bangladesh. DESIGN AND METHOD We analysed data from the food security and nutrition surveillance round 2018-2019. The multistage cluster sampling method was used to select the study population. Hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg and/or having a history of hypertension. We carried out the descriptive analysis, bivariate and multivariable logistic regression to report the weighted prevalence of hypertension as well as crude and adjusted ORs with 95% CI. A p value<0.05 was considered statistically significant. SETTING The study was conducted in 82 clusters (57 rural, 15 non-slum urban and 10 slums) in all eight administrative divisions of Bangladesh. PARTICIPANTS A total of 2482 males and 2335 females aged ≥60 years were included in this analysis. RESULTS The weighted prevalence of hypertension was 42% and 56% among males and females, respectively. The prevalence was higher among females across all sociodemographic, behavioural and clinical strata. Factors associated with higher odds of hypertension (adjusted OR (AOR) (95% CI) for males and females, respectively) were age ≥70 years (1.32 (1.09, 1.60) and 1.40 (1.15, 1.71)); insufficient physical activity (1.50 (1.25, 1.81) and 1.38 (1.15, 1.67)); higher waist circumference (2.76 (2.22, 3.43) and 2.20 (1.82, 2.67)); and self-reported diabetes (1.36 (1.02, 1.82) and 1.82 (1.35, 2.45)). Additionally, living in slums decreased (0.71 (0.52, 0.96)) and education >10 years increased odds of hypertension (1.83 (1.38, 2.44)) among males. CONCLUSION In Bangladesh, half of the elderly persons were hypertensive, with a higher prevalence in females. In both sexes, odds of hypertension was higher among persons with older age (≥70 years), insufficient physical activity, higher waist circumference and self-reported diabetes. The Ministry of Health of Bangladesh should consider these findings while designing and implementing health programmes for elderly population.

Abstract
Background and objective Hypertension, a global burden, is associated with several risk factors and can be treated by lifestyle modifications and medications. Prediction and early diagnosis is important to prevent related health complications. The objective is to construct and compare predictive models to identify individuals at high risk of developing hypertension without the need of invasive clinical procedures. Methods This is a cross-sectional study using 987 records of Qataris and long-term residents aged 18+ years from Qatar Biobank. Percentages were used to summarize data and chi-square tests to assess associations. Predictive models of hypertension were constructed and compared using three supervised machine learning algorithms: decision tree, random forest, and logistics regression using 5-fold cross-validation. The performance of algorithms was assessed using accuracy, positive predictive value (PPV), sensitivity, F-measure, and area under the receiver operating characteristic curve (AUC). Stata and Weka were used for analysis. Results Age, gender, education level, employment, tobacco use, physical activity, adequate consumption of fruits and vegetables, abdominal obesity, history of diabetes, history of high cholesterol, and mother’s history high blood pressure were important predictors of hypertension. All algorithms showed more or less similar performances: Random forest (accuracy = 82.1%, PPV = 81.4%, sensitivity = 82.1%), logistic regression (accuracy = 81.1%, PPV = 80.1%, sensitivity = 81.1%) and decision tree (accuracy = 82.1%, PPV = 81.2%, sensitivity = 82.1%. In terms of AUC, compared to logistic regression, while random forest performed similarly, decision tree had a significantly lower discrimination ability (p-value<0.05) with AUC’s equal to 85.0, 86.9, and 79.9, respectively. Conclusions Machine learning provides the chance of having a rapid predictive model using non-invasive predictors to screen for hypertension. Future research should consider improving the predictive accuracy of models in larger general populations, including more important predictors and using a variety of algorithms.

Prevalence of Hypertension and Associated Factors among the Outpatient Department in Akaki Kality Subcity Health Centers, Addis Ababa, Ethiopia. Int J Hypertens 2020; 2020:7960578. [PMID: 32908691 PMCID: PMC7450304 DOI: 10.1155/2020/7960578] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 04/23/2020] [Accepted: 08/04/2020] [Indexed: 12/11/2022] Open
Abstract
Background Fatalities from hypertension in East Africa are increasing, even though they decreased in western industrial regions. Older age, being female, illiterate, smoking, physical inactivity, and high waist circumferences are major risk factors for the development of hypertension. The prevalence of hypertension among Federal Ministry Civil servants in Addis Ababa, Ethiopia, has found to be high; which is an indication for institution-based hypertension-screening programs. Objective Prevalence of hypertension and associated factors among the outpatient department in Akaki Kality Subcity Health Centers, Addis Ababa, Ethiopia. Methodology. Facility-based cross-sectional study was carried out on systematically sampled 401 out-department patients whose age was greater than or equal to 18 years in four government health centers in Addis Ababa. Data collection took place from March 10, 2018, to April 06 2018. Binary logistic regression analysis was carried out to identify predictors of hypertension. Results Patients had a mean age of 41.17 years (95% CI: 39.77–42.57). The prevalence of hypertension was 14% (95% CI: 13.653–14.347), and 30 (53.57%) were males. Alcohol drinkers were 11.844 times more likely to be hypertensive as compared to non-alcohol drinkers (AOR = 11.844, 95% CI: 3.596–39.014). Cigarette smokers were 16.511 times more likely to be hypertensive as compared to non-cigarette smokers (AOR = 16.511, 95% CI: 4.775–57.084). Khat chewers were 6.964 times more likely to be hypertensive as compared to non-khat chewers (AOR = 6.964, 95% CI: 1.773–26.889). Conclusion The prevalence of patients with hypertension was 14%. Alcohol drinking, cigarette smoking, khat chewing, body mass index ≥25 kg/m2, and age ≥44 years old are major determinants identified by this study. Hence, appropriate management of patients focusing on the relevant associated factors would be of great benefit in controlling hypertension.

Abstract
A systematic review of demographic, socioeconomic, behavioral and anthropometric factors associated with hypertension. We included observational studies, of populations aged 18 or older, from the past ten years, published in English, Portuguese or Spanish from Pubmed, Web of Science, Scopus and Lilacs bases. The most found factors related to the greater chance of having hypertension were age and the Body Mass Index (BMI). Other factors associated with the disease were: gender (male), education (lower education), income (lower income) and waist circumference (high). Never having smoked, never having consumed alcohol and white skin color were characteristics related to a lower chance of having hypertension. As demonstrated, demographic, socioeconomic, behavioral and anthropometric characteristics are important factors associated with a greater chance of having hypertension in the adult population. However, while most of the factors associated with it are amenable to intervention, broader health promotion policies will be needed to reduce socioeconomic inequalities in the prevalence of the disease.

Abstract
OBJECTIVES Low-income and middle-income countries are undergoing epidemiological transition, however, progression is varied. Bangladesh is simultaneously experiencing continuing burden of communicable diseases and emerging burden of non-communicable diseases (NCDs). For effective use of limited resources, an increased understanding of the shifting burden and better characterisation of risk factors of NCDs, including hypertension is needed. This study provides data on prevalence and factors associated with hypertension among males and females 35 years and older in rural Bangladesh. METHODS This is a population-based cross-sectional study conducted in Zakiganj and Kanaighat subdistricts of Sylhet district of Bangladesh. Blood pressure was measured and data on risk factors were collected using STEPS instrument from 864 males and 946 females aged 35 years and older between August 2017 and January 2018. Individuals with systolic blood pressure of ≥140 mm Hg or diastolic blood pressure of ≥90 mm Hg or taking antihypertensive drugs were considered hypertensive. Bivariate and multivariate analyses were performed to identify factors associated with hypertension. RESULTS The prevalence of hypertension was 18.8% (95% CI 16.3 to 21.5) and 18.7% (95% CI 16.3 to 21.3) in adult males and females, respectively. Among those who were hypertensive, the prevalence of controlled, uncontrolled and unaware/newly identified hypertension was 23.5%, 25.9% and 50.6%, respectively among males and 38.4%, 22.6% and 39.0%, respectively among females. Another 22.7% males and 17.8% females had prehypertension. Increasing age and higher waist circumference (≥90 cm for males and ≥80 cm for females) were positively associated with hypertension both in males (OR 4.0, 95% CI 2.5 to 6.4) and females (OR 2.8, 95% CI 2.0 to 4.1). CONCLUSIONS In view of the high burden of hypertension and prehypertension, a context-specific scalable public health programme including behaviour change communications, particularly to increase physical activity and consumption of healthy diet, as well as identification and management of hypertension needs to be developed and implemented.

Abstract
As the prevalence of obesity increases, the prevalence of associated comorbid diseases, obesity-related mortality rates and healthcare costs rise concordantly. Two main factors that hinder efforts to treat obesity include a lack of recognition by patients and documentation by physicians. This study evaluates the relationship between patient perception of obese weight and physician documentation of obesity. This quality improvement observational study surveyed patients of an academic internal medicine clinic on their perception of obesity. Responses were compared to longitudinal physician documentation of obesity and body mass index (BMI). A total of 59.9% of patients with obesity perceived their weight as obese. While 33.7% of patients with a BMI of 30 to 34.9 kg/m2 perceived themselves as having obesity, 71.4% of patients with a BMI of 45 to 49.9 kg/m2 perceived themselves as having obesity. A total of 42.4% of patients with obesity had physician documentation of obesity in the last year. While 25% of patients with a BMI of 30 to 34.9 kg/m2 had physician documentation of obesity, 85.7% of patients with a BMI of 45 to 49.9 kg/m2 had physician documentation of obesity. For patients with a BMI ≥50 kg/m2 , 52.9% perceived their weight to be obese and 76.5% had physician documentation of obesity in the last year. Both patient perception and physician documentation of obesity were significantly less than the prevalence of obesity. Patient perception of obesity and provider documentation of obesity increased as BMI increased until a BMI ≥50 kg/m2 . Both patients and providers must improve recognition of this disease.

Abstract
Background Hypertension is a major cardiovascular risk factor that is linked with fatal complications and is an overwhelming global challenge. Primary prevention is a key to control hypertension with identification of major risk factors. This study was aimed at assessing the prevalence and factors associated with hypertension. Methods Community-based cross-sectional study was conducted among 903 adults aged 25 to 64 years in Dire Dawa City, East Ethiopia. Data were collected using World Health Organization (WHO) STEPwise approach to Surveillance (STEPS) for non-communicable disease (NCD) standard survey tool. Multivariate logistic regression models were used to identify relative effects of distal, proximal, and immediate risk factors of hypertension, and all statistical tests were declared significantly at P-value<0.05. Results The average SBP and DBP were 124.98±17.18 mmHg and 78.92±10.13 mmHg, respectively. The prevalence of hypertension was 24.43% (95% CI: 21.57, 27.28). Majority (51.64%) of adults were not aware of their elevated blood pressure status. hypertension was significantly associated with the age group 30-44 (aOR 3.61, 95% CI: 2.0, 6.55), 45-54 (aOR 5.36, 95% CI: 2.62, 10.91), and 55-64 (aOR 9.38, 95% CI: 4.73, 18.59), being unemployed (aOR 1.68, 95%CI: 1.03, 2.77), ever smoking (aOR 1.89, 95% CI: 1.04, 2.23), having abdominal obesity (aOR 1.72, 95% CI: 1.13, 2.64), and BMI≥25 kg/m2 (aOR 1.48, 95%CI: 1.01, 2.15). Conclusion Moderately high prevalence of hypertension was observed among adults in study setting demonstrating a major public health problem. Majority of adults with hypertension in study setting were not aware of their elevated BP status highlighting the burden of the hidden morbidity and subsequent complications. Community level intervention and routine assessment of sociodemographic, behavioral, and biophysiological risk factors, screening, and diagnosis of NCDs should be institutionalized to address the occult burden.

Abstract
BACKGROUND Apelin is a peptide ligand of the G-protein-coupled receptor APJ and exhibits anti-diabetes and anti-heart failure activities. However, short serum half-life of the apelin peptide limits its potential clinical applications. This study aimed to develop a long-acting apelin analog. METHODS To extend apelin's in vivo half-life, we made a recombinant protein by fusing the IgG Fc fragment to apelin-13 (Fc-apelin-13), conducted pharmacokinetics studies in mice, and determined in vitro biological activities in suppressing cyclic adenosine monophosphate and activating extracellular signal-regulated kinase signalling by reporter assays. We investigated the effects of Fc-apelin-13 on food intake, body weight, fasting blood glucose and insulin levels, glucose tolerance test, hepatic steatosis, and cardiac function and fibrosis by subcutaneous administration of Fc-apelin-13 in diet-induced obese mice for 4 weeks. RESULTS The estimated half-life of Fc-apelin-13 in blood was approximately 33 hours. Reporter assays showed that Fc-apelin-13 was active in suppressing cyclic adenosine monophosphate response element and activating serum response element activities. Four weeks of Fc-apelin-13 treatment in obese mice did not affect food intake and body weight, but resulted in a significant improvement of glucose tolerance, and a decrease in hepatic steatosis and fibrosis, as well as in serum alanine transaminase levels. Moreover, cardiac stroke volume and output were increased and cardiac fibrosis was decreased in the treated mice. CONCLUSIONS Fc-apelin-13 fusion protein has an extended in vivo half-life and exerts multiple benefits on obese mice with respect to the improvement of glucose disposal, amelioration of liver steatosis and heart fibrosis, and increase of cardiac output. Hence, Fc-apelin-13 is potentially a therapeutic for obesity-associated disease conditions.

Abstract
Background Hypertension is a public health problem and obesity is becoming an epidemic, increasing the risk of hypertension. Both are risk factors for cardiovascular diseases (CVD). Methods A case control study recruiting 102 patients aged ≥60 years, divided into 55 cases with hypertension and 47 controls without. Body mass index (BMI), waist circumference (WC) and waist to height ratio (WHtR) were measured as well as lipid profile then Framingham risk score (FRS) was calculated. Results Odds ratio (OR) for hypertension and medium to high risk cardiovascular events was the same in female patients using WC and WHtR. In male patients, only WHtR increased the risk for hypertension and for cardiovascular events, OR significantly increased with higher WHtR compared to WC. Conclusion WHtR and WC are strong risk factors for hypertension and cardiovascular events in Egyptian elderly female patients. WHtR is the best anthropometric predictor for hypertension and cardiovascular events in male patients.

Abstract
AIMS To describe the prevalence of abdominal obesity and its association with cardio metabolic risk factors among older adults in Ecuador. MATERIALS AND METHODS The present study used data from the National Survey of Health, Wellbeing, and Aging survey to examine the prevalence of abdominal obesity according to certain demographic, behavioral, and health characteristics of the participants. Logistic regression models adjusted for potential confounders were used to evaluate the association of abdominal obesity with cardio metabolic risk factors. RESULTS Of 2053 participants aged 60 years and older, the prevalence of abdominal obesity was 65.9% (95% CI; 62.2%, 69.4%) in women and 16.3% (95% CI; 13.8%, 19.2%) in men. Notably, a higher prevalence of abdominal obesity was seen among residents in the urban areas of the country, those who reported their race as black or mulatto, individuals with sedentary lifestyle and obesity, and older adults with greater number of comorbidities. Moreover, after adjustment for potential confounders, women with abdominal obesity were 2.0, 2.8, and 1.6 times more likely to have diabetes, the metabolic syndrome, and hypertriglyceridemia as compared with those without, respectively. Likewise, men with abdominal obesity had 51% and 22% higher rates of hypertension and diabetes than their non-obese counterparts, respectively. CONCLUSIONS the prevalence of abdominal obesity is high among older adults in Ecuador. Moreover, abdominal obesity is significantly associated with cardio metabolic risk factors. Therefore, further research is needed to evaluate sociodemographic and nutritional determinants of this emerging public health burden among older Ecuadorians.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been used more frequently over the past 10 years. As the population ages, a larger number of older people will suffer from weight-related comorbidities, resulting in bariatric surgery becoming a dominant solution for improving health and quality of life. We assessed the long-term outcomes of LSG in elderly patients. METHODS We conducted a retrospective chart review of patients who underwent LSG between January 2007 and August 2009. We subdivided 123 patients into <35 (n = 43), 35-55 (n = 59), and >55 (n = 21) age groups. RESULTS The respective mean excess body mass index loss and excess weight loss were 42.5% ± 3.1% and 41.3% ± 12.3% for the <35 age group, 48.7% ± 4.1% and 45.6% ± 10.6% for the 35-55 age group, and 53.6% ± 4.6% and 52.1% ± 11.1% for the >55 age group. The follow-up compliance rates at the 5-year visit were 23.85, 31.11, and 47.61% for the <35, 35-55, and >55 age groups, respectively. The corresponding Bariatric Analysis and Reporting Outcome System scores were 3.7 ± 1.1, 4.0 ± 0.7, and 5.3 ± 1.3. The comorbidities of all the patients improved significantly, with a non-significant distribution between the three groups for each comorbidity. CONCLUSIONS LSG is a useful tool for people who want to modify their eating habits and lose weight healthily. This study suggests that long-term weight loss, improvements in comorbidity, and compliance to follow-up are significant for patients >55 years old.

Abstract
INTRODUCTION: Safe, effective weight loss with resolution of comorbidities has been convincingly demonstrated with bariatric surgery in the aged obese. They, however, lose less weight than younger individuals. It is not known if degree of weight loss is influenced by the choice of bariatric procedure. The aim of this study was to compare the degree of weight loss between laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients above the age of 50 years at 1 year after surgery. MATERIALS AND METHODS: A retrospective analysis was performed of all patients more than 50 years of age who underwent LSG or LRYGB between February 2012 and July 2013 with at least 1 year of follow-up. Data evaluated at 1 year included age, sex, weight, body mass index (BMI), mean operative time, percentage of weight loss and excess weight loss, resolution/remission of diabetes, morbidity and mortality. RESULTS: Of a total of 86 patients, 54 underwent LSG and 32 underwent LRYGB. The mean percentage of excess weight loss at the end of 1 year was 60.19 ± 17.45 % after LSG and 82.76 ± 34.26 % after LRYGB (P = 0.021). One patient developed a sleeve leak after LSG, and 2 developed iron deficiency anaemia after LRYGB. The remission/improvement in diabetes mellitus and biochemistry was similar. CONCLUSION: LRYGB may offer better results than LSG in terms of weight loss in patients over 50 years of age.

Abstract
BACKGROUND Hypertension, an important risk factor for the health of human being, is often accompanied by various comorbidities. However, the incidence patterns of those comorbidities have not been widely studied. AIM Applying big-data techniques on a large collection of electronic medical records, we investigated sex-specific and age-specific detection rates of some important comorbidities of hypertension, and sketched their relationships to reveal the risk for hypertension patients. METHODS We collected a total of 6,371,963 hypertension-related medical records from 106 hospitals in 72 cities throughout China. Those records were reported to a National Center for Disease Control in China between 2011 and 2013. Based on the comprehensive and geographically distributed data set, we identified the top 20 comorbidities of hypertension, and disclosed the sex-specific and age-specific patterns of those comorbidities. A comorbidities network was constructed based on the frequency of co-occurrence relationships among those comorbidities. RESULTS The top four comorbidities of hypertension were coronary heart disease, diabetes, hyperlipemia, and arteriosclerosis, whose detection rates were 21.71% (21.49% for men vs 21.95% for women), 16.00% (16.24% vs 15.74%), 13.81% (13.86% vs 13.76%), and 12.66% (12.25% vs 13.08%), respectively. The age-specific detection rates of comorbidities showed five unique patterns and also indicated that nephropathy, uremia, and anemia were significant risks for patients under 39 years of age. On the other hand, coronary heart disease, diabetes, arteriosclerosis, hyperlipemia, and cerebral infarction were more likely to occur in older patients. The comorbidity network that we constructed indicated that the top 20 comorbidities of hypertension had strong co-occurrence correlations. CONCLUSIONS Hypertension patients can be aware of their risks of comorbidities based on our sex-specific results, age-specific patterns, and the comorbidity network. Our findings provide useful insights into the comorbidity prevention, risk assessment, and early warning for hypertension patients.

Abstract
BACKGROUND The concept of body mass index (BMI) may not be well understood by patients. The purpose of this study was to evaluate patients' knowledge of BMI in the primary care setting. METHODS Adult patients seen in 18 practices in West Virginia and New Jersey were invited to complete a voluntary survey. The survey assessed the patient's baseline knowledge of BMI as well as demographic information and whether the patient had known chronic conditions associated with increased BMI, including hypertension, hyperlipidemia, diabetes mellitus, and sleep apnea. RESULTS While the majority (59.9%) of primary care patients knew the meaning of BMI and that it is related to obesity, there was little knowledge of BMI cutoff values; more than 80% of responses were incorrect when asked to define specific BMI levels and their meaning. Self-awareness of obesity was limited as well, with only 16.4% aware of their own personal BMI. Furthermore, nearly 70% of patients could not recall having discussed BMI with their physician. CONCLUSION Findings indicate low comprehension of the term BMI. Increasing awareness of BMI may help patients address this key risk factor and significantly affect public health.

Abstract
INTRODUCTION The body mass index (BMI) and waist circumference (WC) are a risk of hypertension, but their potentially multiplicative effect on hypertension is underexplored. AIM To examine modifying effects of BMI and WC on hypertension using a nationally representative U.S. adult sample stratified by gender. METHODS Data were derived from the 2009-2010 NHANES. Overweight and obesity were based on BMI of 25.0-29.9 and ≥30 kg/m(2), respectively. High-risk WC was based on ≥102.0 and ≥88.0 cm for males and females, respectively. Hypertension was determined by systolic/diastolic blood pressure of ≥140/≥90 mmHg, or taking prescribed medications. Logistic regression was used to examine the association between hypertension and BMI and WC by gender. Interaction terms were added to examine if BMI modified the effect of WC on hypertension. RESULTS Both BMI and WC were significant predictors of hypertension in overall population. Gender-specific models indicated that BMI played an important role in hypertension risk among males, but WC in females. The interaction effects were present among males implying that the association of WC with hypertension was stronger if subjects were overweight or obese. This effect, however, was not present in females. CONCLUSION BMI and WC may influence hypertension differently among males and females.

Abstract
BACKGROUND There remains controversy regarding which of the anthropometric indicators best defines obesity. In this study, we compared the efficacy of using body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) in the diagnosis of obesity and assessed their associations with diabetes, hypertension, and dyslipidemia in an urban working population in China. METHODS Anthropometric measurements, blood pressure, plasma lipids, fasting and 2-hour plasma glucose (PG) levels by a 75 gram oral glucose tolerance test (OGTT) were obtained from 2603 working Chinese who had no history of cardiovascular diseases or diabetes. Cardio-metabolic risk factors including high blood pressure, dyslipidemia, and glucose intolerance were evaluated. The diagnoses of overweight and obesity were based on the WHO definitions with BMI for general obesity and WC and WHR for central obesity. RESULTS Based on BMI, WC and WHR, there were 31.3%, 16.6%, 35.2% of the studied subjects, respectively, being overweight and 2.0%, 5.6%, 9.2% being obese. Among women but not men, more overweight and obese subjects were diagnosed using WHR and WC. The number of cardio-metabolic risks was higher by WC criterion than BMI and WHR in the whole group (p <0.05) and female subjects (p <0.01). Comparing the three anthropometric indexes predicting hypertension, hyperglycemia, dyslipidemia and multiple cardio-metabolic risks, for women, it was WC having the largest areas under ROC curves (0.759, 0.746, 0.701 and 0.773 respectively); while in men, it was WC for hypertension, WHR for hyperglycemia, BMI for dyslipidemia and WC for multiple cardio-metabolic risks (areas under ROC curves were 0.658, 0.686, 0.618 and 0.695 respectively). CONCLUSIONS Among Chinese working population, the need of lower cutoff values to define overweight and obesity were observed. Central obesity indicator (WC) is the preferred measure to predict the presence of cardio-metabolic risk in Chinese female subjects.

Abstract
OBJECTIVES To determine whether the prevalence of chronic kidney disease (CKD) in England has changed over time. DESIGN Cross-sectional analysis of nationally representative Health Survey for England (HSE) random samples. SETTING England 2003 and 2009/2010. SURVEY PARTICIPANTS 13,896 adults aged 16+ participating in HSE, adjusted for sampling and non-response, 2009/2010 surveys combined. MAIN OUTCOME MEASURE Change in prevalence of estimated glomerular filtration rate (eGFR)<60 mL/min/1.73 m2 (as proxy for stage 3-5 CKD), from 2003 to 2009/2010 based on a single serum creatinine measure using an isotope dilution mass spectrometry traceable enzymatic assay in a single laboratory; eGFR derived using Modified Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKDEPI) eGFR formulae. ANALYSIS Multivariate logistic regression modelling to adjust time changes for sociodemographic and clinical factors (body mass index, hypertension, diabetes, lipids). A correction factor was applied to the 2003 HSE serum creatinine to account for a storage effect. RESULTS National prevalence of low eGFR (<60) decreased within each age and gender group for both formulae except in men aged 65-74. Prevalence of obesity and diabetes increased in this period, while there was a decrease in hypertension. Adjustment for demographic and clinical factors led to a significant decrease in CKD between the surveyed periods. The fully adjusted OR for eGFR<60 mL/min/1.73 m2 was 0.75 (0.61 to 0.92) comparing 2009/2010 with 2003 using the MDRD equation, and was similar using the CKDEPI equation 0.73 (0.57 to 0.93). CONCLUSIONS The prevalence of a low eGFR indicative of CKD in England appeared to decrease over this 7-year period, despite the rising prevalence of obesity and diabetes, two key causes of CKD. Hypertension prevalence declined and blood pressure control improved but this did not appear to explain the fall. Periodic assessment of eGFR and albuminuria in future HSEs is needed to evaluate trends in CKD.

Abstract
Obesity and osteoporosis are two important body composition problems with increasing prevalences in aged populations. Traditionally, obesity has been regarded as being beneficial to bone health. However, the protective effect of obesity on osteoporosis has been questioned. In some recent studies, obesity, as defined by percentage body fat, was regarded as a risk factor for osteoporosis. The purpose of this study was to (1) evaluate the effect of waist circumference, a surrogate measure for abdominal obesity, on bone mineral content (BMC) and (2) examine whether the effect of waist circumference increases with advancing age. The study population is made up of women aged over 45 years who completed the body composition and bone mineral density examinations in the fifth Korea National Health and Nutrition Examination Survey in 2010. Subjects who take estrogen or are under medical treatment for osteoporosis were excluded. Stroke patients are also excluded. Femoral neck, total-hip, and whole-body BMC were measured by dual-energy X-ray absorptiometry. A total of 1,434 subjects were included in the analysis. Waist circumference was negatively associated with BMC in all tested regions after correction for weight, menopausal status, smoking, drinking, and exercise. In addition, the negative association between waist circumference and BMC in the femoral neck and total hip increases with age, after correction for confounding factors, showing an interaction effect between waist circumference and age on BMC. In conclusion, this study shows that the negative relationship between waist circumference and BMC in the femoral neck and total hip is greater for older women.

Abstract
OBJECTIVES Childhood obesity is a public health concern in Portugal. Socio-demographic and behavioral factors are highly associated with obesity but are not clearly understood. This article aims to update the prevalence of overweight and obesity in Portuguese children and to explore the influence and risks of socio-demographic factors and behavioral factors. METHODS A cross-sectional study of Portuguese children aged 3-10 years from all 18 mainland districts took place between March 2009 and January 2010. The sample was composed by 17,136 children, 3-10 years of age (8,455 boys; 8,681 girls). Height, weight, and other anthropometric measurements were obtained by trained technicians. Body mass index (BMI) was calculated along with other anthropometric variables. Data analyses took place between April and September 2012. The overweight/obesity classification was established by age-and sex-specific BMI cut-off points as defined by the International obesity task force (IOTF). Parents completed questionnaires about socio-demographic and behavioral characteristics of the family. RESULTS Almost 28% of the Portuguese children were overweight or obese (19.7% overweight; 8.2% obese). Prevalence was greater in girls than in boys. Logistic regression models found that the odds of childhood obesity were significantly affected by biological, socio-demographic, and behavioral factors. CONCLUSIONS The protective factors against childhood overweight/obesity in this sample of Portuguese children are: (i) being male; (ii) having been breastfeed; (iii) having been born from mothers who did not smoke during pregnancy; (iv) engaging in little sedentary behaviors (TV, PC, and playing electronic games); (iv) performing at least 1 h of moderate physical activity every day; and (v) having parents with higher educational levels who also have their BMI within the healthy ranges.

Abstract
No envelhecimento, hábito inativo está associado a doenças crônicas. Existem diferentes domínios da atividade física, tais como: tempo livre e locomoção. O objetivo foi analisar associações entre diferentes domínios de atividade física, comorbidades e idade em hipertensos. Foram entrevistados 192 hipertensos. Classificados em menos ativos e mais ativos para atividades no lazer, locomoção, ocupação e total e estratificados em grupos etários. A circunferência de cintura foi avaliada e comorbidades auto referidas. O teste Qui-quadrado analisou as associações e o teste ANOVA one way comparou os grupos etários, adotando significância estatística quando p<0,05. As médias de atividade física ocupacional e total foram menores para idade igual ou acima dos 60 e 70 anos, respectivamente. A atividade ocupacional esteve associada à idade em mulheres e, ao colesterol e diabetes em homens, que também tiveram atividade física de locomoção associada à circunferência de cintura. Em síntese a atividade física de hipertensos associa-se a comorbidades para diferentes grupos etários e sexos.

Abstract
OBJECTIVE There are limited controlled data for intragastric balloons (IGB) in obesity treatment. This randomized, controlled study evaluated the efficacy and safety of an IGB in obese individuals with metabolic syndrome (MS). DESIGN AND METHODS Sixty-six adults (BMI: 30-40 kg/m(2)) were randomized to IGB for 6 months, with a 12 month behavioral modification (IGB Group; "IGBG"), or 12 month behavioral modification alone (Control Group; "CG"). The primary outcome was percentage change in body weight. RESULTS Thirty-one subjects (female: 68%; mean age: 43; mean BMI: 36.0) were randomized to IGBG and 35 (66%; 48; 36.7) to CG. At 6 months, there was a significantly greater weight loss in the IGBG: -14.2 vs. -4.8; P < 0.0001. This was associated with a significantly greater reduction in waist circumference, and an improvement in quality of life, with a trend for a larger %MS remission (50% vs. 30%; n.s.). At month 12, the differences in weight loss were enduring: -9.2 vs. -5.2; P = 0.007. Gastrointestinal-related adverse events were common in the IGBG, resolving predominantly within two weeks. The IGB was removed prematurely in three subjects (one for refractory gastrointestinal symptoms). CONCLUSIONS Statistically significant and clinically relevant improvements in weight loss and health outcomes were observed with the IGBG at 6 months versus behavioral modification alone. The differential weight loss was still evident 6 months after IGB removal.

Safety and efficacy of laparoscopic adjustable gastric banding in patients aged seventy and older. Surg Obes Relat Dis 2013; 10:284-9. [PMID: 24582414 DOI: 10.1016/j.soard.2013.06.022] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2013] [Revised: 06/04/2013] [Accepted: 06/25/2013] [Indexed: 11/22/2022]
Abstract
BACKGROUND Life expectancy is increasing, with more elderly people categorized as obese. The objective of this study was to assess the effects of laparoscopic adjustable gastric banding (LAGB) on patients aged ≥ 70 years. METHODS This was a retrospective analysis of patients aged ≥ 70 years who underwent LAGB at our university hospital between 2003 and 2011. The data included age, weight, body mass index (BMI), and percentage excess weight loss (%EWL) obtained before and after gastric banding. Operative data, length of stay, postoperative complications, and resolution of co-morbid conditions were also analyzed. RESULTS Fifty-five patients aged ≥ 70 years (mean 73 years) underwent gastric banding between 2003 and 2012. Mean preoperative weight and BMI were 123 kilograms and 45 kg/m(2), respectively. On average, each patient had 4 co-morbidities preoperatively, with hypertension (n = 49; 86%), dyslipidemia (n = 40; 70%), and sleep apnea (n = 31; 54%) being the most common. Mean operating room (OR) time was 49 minutes, with all patients discharged within 24 hours. There was 1 death at 4 years from myocardial infarction, no intensive care unit admissions, and no 30-day readmissions. Mean %EWL at 1, 2, 3, 4, and 5 years was 36 (± 12.7), 40 (± 16.4), 42 (± 19.2), 41 (± 17.1), 50 (± 14.9), and 48 (± 22.6), respectively. Follow-up rates ranged from 55/55 (100%) at 6 months to 7/9 (78%) of eligible patients at 5 years and 2/2 (100%) at 8 years. Complications included 1 band slip at year 5, 1 band removed for intolerance, and 1 port site hernia. The resolution of hypertension, dyslipidemia, sleep apnea, lower back pain, and non-insulin-dependent diabetes was 27%, 28%, 35%, 31%, and 35%, respectively. CONCLUSIONS LAGB as a primary treatment for obesity in carefully selected patients aged ≥ 70 can be well tolerated and effective with moderate resolution of co-morbid conditions and few complications.

Binge eating as a determinant of emotional state in overweight and obese males with cardiovascular disease. Maturitas 2013; 74:352-6. [PMID: 23395403 DOI: 10.1016/j.maturitas.2013.01.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2012] [Revised: 01/02/2013] [Accepted: 01/08/2013] [Indexed: 11/22/2022]
Abstract
OBJECTIVES The present study investigates the association between depression, anxiety and binge eating at baseline with weight-change after an approximately 1-year period in a clinical sample of obese adult males with cardiovascular disease. METHODS At the time of the first measurement, the sample consisted of 69 overweight and obese men (age range between 36 and 74); 34 patients attended a follow-up measurement 6-17 months after the first measurement, and completed selected psychological instruments. RESULTS After the follow-up period, only 28.7% patients' lost weight, 29.9% patients' had the same weight, and finally 41.4% patients' gained weight. When comparing the first and the second assessments, the level of anxiety and depression is relatively stable. Men, who, at the time of the second assessment, gained weight, and were binge eating at baseline, were more depressed and anxious in comparison with the other two groups of patients. CONCLUSIONS It is necessary to focus primarily on binge eating symptoms as a part of weight reduction treatment as well as to treat anxiety and depression in CVD patients. Binge eating is an eating disorder per se, and therefore it is important to treat it before the person starts weight reduction procedures as part of the risk prevention treatment for CVD patients.

Abstract
Effective weight loss and reduction in comorbidities has been convincingly demonstrated with bariatric surgery. Concerns regarding increased perioperative complications and poor results have led to a reluctance to offer such surgery to older patients. We performed a systematic review and meta-analysis of the published evidence for those in the ≥55-year age group. An electronic search was conducted of MEDLINE, EMBASE, and the Cochrane Library databases from 1990 to December 2010. We included laparoscopic studies published in English where the results were broken down by surgical procedure, reporting a minimum 6-month follow-up for ≥10 patients aged ≥55. After an initial screen of 2,543 titles, 298 abstracts were reviewed. Eighteen studies were included in the analysis. Of these, 10 included patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) (663 patients), and 11 included patients undergoing laparoscopic adjustable gastric banding (LAGB) (543 patients). Meta-analyses of body mass index (BMI) reductions indicated sustained and clinically significant BMI reductions for both RYGB (mean percentage of excess weight loss at 1 year, 72.6 %) and LAGB (mean percentage of excess weight loss at 1 year, 39.1 %). The 30-day mortality was 0.30 and 0.18 % for LRYGB and LAGB, respectively. Meta-analysis of old versus young patients revealed better comorbidity and mortality outcomes for younger patients. Bariatric surgery for patients ≥55 years achieves weight loss and reduction in comorbidities and mortality comparable to the general bariatric surgery population. Based on the above findings, patients should not be denied bariatric surgery on the basis of age alone.

Abstract
OBJECTIVE In recent analyses of data from a large community sample, negative cross-sectional and prospective associations between cardiac stress reactivity and obesity were observed. The present study reexamined the association between cardiovascular reactivity and adiposity in the Dutch Famine Birth Cohort, with the additional aim of examining the association between cortisol reactivity and adiposity. METHODS Blood pressure, heart rate, and salivary cortisol were measured at rest and in response to standard laboratory stress tasks in 725 adults. Height, weight, waist-and-hip circumference, and skinfold thickness were measured. Between 4 to 7 years later, 460 participants reported current height and weight. Obesity was defined as a body mass index of 30 kg/m(2) or higher. RESULTS Those with a greater body mass index (β = -0.39 beats per minute (bpm)), waist-to-hip ratio (β = -0.15 bpm), and triceps and subscapular skinfold thicknesses (β = -1.0 and -1.8 bpm) or who were categorized as obese (-3.9 bpm) displayed smaller cardiac reactions to acute stress (all p < .001). With the exception of waist-to-hip ratio, the same negative associations emerged for cortisol reactivity (all p ≤ .01). In prospective analyses, low cardiac reactivity was associated with an increased likelihood of becoming or remaining obese in the subsequent 4 to 7 years (odds ratio = 1.03, p = .01). All associations withstood adjustment for a range of possible confounders. CONCLUSIONS The present analyses provide additional support for the hypothesis that it is low not high cardiac and cortisol stress reactivity that is related to adiposity.

Goacher PJ, Lambert R, Moffatt PG. Can weight-related health risk be more accurately assessed by BMI, or by gender specific calculations of Percentage Body Fatness? Med Hypotheses 2012; 79:656-62. [PMID: 22939766 DOI: 10.1016/j.mehy.2012.08.003] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2012] [Revised: 07/10/2012] [Accepted: 08/03/2012] [Indexed: 01/23/2023]
Abstract
The problem of obesity over the last 10 years has consistently been referred to as a 'global epidemic'. The Body Mass Index (BMI) is the currently accepted measure for classifying weight-related risk, but is a crude measure that has not changed in 150 years. It is recognised as having significant limitations, largely due to its lack of distinction between fat and muscle tissue. As the health risks of obesity are linked to the fat content of the body, a more accurate method of classifying would be Percentage Body Fatness (PBF). Although skinfold thickness analysis is recognised as a valid and accurate estimate of PBF in field studies, this method is not routinely used in clinical practice. Using data collected from young adults in the United Kingdom, we compared classifications (underweight, normal weight, overweight and obese) using BMI, with classifications using estimated PBF (from skinfold thickness analysis). We identified disparity between these two methods in approximately 1/3 of participants. BMI correctly classified 66.5% of females and 62.7% of males, with different gender profiles of incorrect classification. Regression analysis was conducted using estimated PBF (by skinfold thickness analysis) as the dependent variable, with explanatory variables of age, height, weight, systolic blood pressure, frequency of vigorous exercise and grip strength. The resulting gender-specific formulae derived from this regression analysis provides a regression R(2) of around 65%, and improved correct classifications to 74% for females and 76% for males. This represents an average improvement of roughly ten percentage points over BMI (male: 7.2% points; female: 13.4% points). We hypothesise that the presented formulae provide gender-specific calculations of PBF, which result in a more accurate indicator of weight-related health risk, compared with BMI in this population. This provides a new approach to an increasingly important clinical issue. These formulae use data that can be easily, quickly and cost-effectively measured in a practice setting. If shown to be repeatable with larger and more diverse populations, the PBF formulae could provide an alternative to the BMI as the major indicator of body-composition related health risk. This would ensure resources are targeted more appropriately and efficiently.

Abstract
Diabetes and hypertension are major independent risk factors for cardiovascular and renal diseases; however, prevalence and characteristics of the coexistence in general population is not clear. Data from Thai National Health Examination Survey III were used to estimate the prevalence of coexistence of diabetes and hypertension, and to estimate the proportion of awareness, treatment and control of both conditions. A total of 36,877 (male 17,614 and female 19,263) participants were included in the study. The prevalence of people with diabetes and hypertension was 3.2% (male 2.8% and female 3.6%). Approximately half of the diabetes patients (49.0%, 95%CI 45.6, 52.5) had hypertension, and 14.4% (95%CI 13.0, 16.0) of hypertensive patients had diabetes. After controlling for covariates, factors associated with coexistence of diabetes and hypertension included; age ≥60 years (adjust odds ratio 1.38, 95%CI 1.14, 1.73), having education less than 6 years (1.83, 95%CI 1.03, 3.38) and abdominal obesity (2.49, 95%CI 2.00, 3.10). More than 80% were unaware of having both conditions. Target for control of both glucose and blood pressure among those treated was achieved in only 6.2%. In conclusion, patients with diabetes or hypertension should be promoted to have weight control and screening for the comorbidity.

Abstract
BACKGROUND Obesity is a risk factor for both chronic kidney disease (CKD) and cardiovascular disease. The association of simple indices of obesity with CKD remains poorly understood. Evidence suggests that measures of central obesity such as waist circumference (WC) and waist-to-hip ratio (WHR) are more accurate predictors of morbidity and cardiovascular risk than body mass index (BMI). This study aimed to investigate the association of BMI, WC and WHR with CKD risk in a population screened for type 2 diabetes. METHODS Data were drawn from a population-based screening programme of 6475 volunteers without pre-existing diabetes. A number of investigations and cardiovascular health-related assessments were performed. Participants were categorized into two groups: those with an estimated glomerular filtration rate (eGFR) ≥60 and <60 mL/min/1.73m(2). Participants were also categorized as low, medium and high risk according to each anthropometric variable. RESULTS CKD was independently associated with higher WC and BMI (P < 0.01) but not WHR (P = 0.47). Increasing obesity measured by BMI and WC was associated with a reduction in eGFR for both men and women (P < 0.001). Increasing risk categories for BMI and WC were also associated with lower eGFR in men and women (P < 0.001). Combining anthropometric measures provided no additional measure of risk for underlying CKD. CONCLUSIONS WC may be a simple and reliable clinical tool for the detection of underlying CKD within primary care. Given the complex interaction between adiposity and uraemia, a combined screening tool using BMI and WC or WHR is unlikely to provide any additional benefit to risk analysis.

Abstract
INTRODUCTION Hepatic, pancreatic and biliary (HPB) cancers are a group of diverse malignancies managed ideally in specialist centres. This study describes recent patterns in the incidence and survival of HPB cancers in England over a ten year period (1998-2007). METHODS Data on 99,379 English patients (50,656 males; 48,723 females) diagnosed with HPB cancers between 1998 and 2007 were extracted from the National Cancer Data Repository. Data were divided into six site-specific cancer groups; pancreas, ampulla of Vater, biliary tract, primary liver, gallbladder and duodenum. Age-standardised incidence rates (per 100,000 European standard population, (ASR(E))) were calculated for each of the six groups by year of diagnosis and by socioeconomic deprivation. Survival was estimated using the Kaplan-Meier method. RESULTS The largest group was pancreatic cancers (63%), followed by primary liver (14%) and biliary cancers (13%). ASR(E) were highest for pancreatic and primary liver cancers whereas cancers of the gallbladder, duodenum and ampulla of Vater had a very low incidence. Over time the incidence of all six groups remained relatively stable, although primary liver cancer increased slightly in males. Incidence rates were higher in males than in females in all groups except gallbladder cancer, and all six groups had a higher incidence in the more deprived quintiles. Overall survival was poor in each of the HPB cancer groups. CONCLUSIONS HPB tumours are uncommon and are associated with poor long term survival reflecting the late stage at presentation. Incidence patterns suggest variable rates linked to socioeconomic deprivation and highlight a male predominance in all sites except the gallbladder. Identification of high risk populations should be emphasised in initiatives to raise awareness and facilitate earlier diagnosis.

Abstract
The use of animal models is an essential part of medical research and drug development. The essential skills required to be able to do such research includes experimental design, statistical analysis and the actual handling and treating of the animals (in vivo skills). The number of students in the U.K. receiving training in handling and experimenting on animals has declined rapidly in the last few decades which has led to initiatives to increase numbers of students with these skills to meet demand. Within the Department of Pharmacology and Therapeutics at King's College London, we run a course for 2nd year undergraduates entitled "Animal models of disease and injury". This course not only covers the theoretical and ethical aspects of using animals in research, but also contains practical laboratory classes in which students get hands-on experience using animals. One of the laboratory classes we run is a glucose tolerance test in obese and lean mice. This is an example of research-led teaching which aims to develop research skills through engaging students in research like activities. In this paper, we outline the methodology of the glucose tolerance practical and highlight some of the skills we and the students think they gain by research-led teaching such as this.

Abstract
Scientific findings show that substance abuse in women yields a higher risk of a variety of health problems than substance abuse in men. Research suggests that women experience addiction telescoping when they abuse alcohol, tobacco, specific stimulants, and possibly opioids. Medical side effects also develop more rapidly in women than men when they abuse many substances. Cancer and cardiac complications, specifically, pose a significant threat for women who abuse almost all types of substances. However, the physical consequences are not the only ones women suffer when they engage in substance abuse. Research on substance abuse in women ties opioids to mood and anxiety disorders, heroin to neurological deficiencies, cocaine to immune system suppression, and alcohol to intimate partner abuse. Additionally, female substance abusers, on average, have a lower level of education and lower rates of employment. In light of these gender-specific concerns, physicians should give particular consideration to detecting substance abuse in women.

Abstract
Background Considering the increasing trend of obesity reported in current data, this study was conducted to examine trends of obesity and abdominal obesity among Tehranian adults during a median follow-up of 6.6 years. Methods Height and weight of 4402 adults, aged 20 years and over, participants of the Tehran Lipid and Glucose Study (TLGS), were measured in 1999-2001(phase I) and again in 2002-2005(phase II) and 2006-2008 (phase III). Criteria used for obesity and abdominal obesity defined body mass index (BMI) ≥ 30 and waist circumference ≥ 94/80 cm for men/women respectively. Subjects were divided into10-year groups and the prevalence of obesity was compared across sex and age groups. Results The prevalence of obesity was 15.8, 18.6 and 21% in men and 31.5, 37.7 and 38.6% in women in phases I, II and III respectively (p < 0.001). The prevalence of abdominal obesity in men was 36.5, 57.2 and 63.3% and in women was 76.7, 83.8 and 83.6% in the three periods mentioned (p < 0.001). Men aged between 20-29 years had highest increase rates of obesity and abdominal obesity in phase III in comparison with phase I (with a respective rates of 2.2- and 3.3-fold). In both sexes, an increased trend was observed between phases I and II, whereas between phases II and III, this trend was observed in men, but not in women. Conclusion This study demonstrates alarming rises in the prevalences of both obesity and abdominal obesity in both sexes especially in young men, calling for urgent action to educate people in lifestyle modifications.

Abstract
OBJECTIVES To examine changes in public perceptions of overweight in Great Britain over an eight year period. DESIGN Comparison of data on self perceived weight from population surveys in 1999 and 2007. SETTING Household surveys of two representative samples in Great Britain. PARTICIPANTS 853 men and 944 women in 1999, and 847 men and 989 women in 2007. MAIN OUTCOME MEASURES Participants were asked to report their weight and height and classify their body size on a scale from "very underweight" to "obese." RESULTS Self reported weights increased dramatically over time, but the weight at which people perceived themselves to be overweight also rose significantly. In 1999, 81% of overweight participants correctly identified themselves as overweight compared with 75% in 2007, demonstrating a decrease in sensitivity in the self diagnosis of overweight. CONCLUSIONS Despite media and health campaigns aiming to raise awareness of healthy weight, increasing numbers of overweight people fail to recognise that their weight is a cause for concern. This makes it less likely that they will see calls for weight control as personally relevant.

Abstract
BACKGROUND The metabolic syndrome consists of a cluster of atherosclerotic risk factors, many of which also have been implicated in the genesis of atrial fibrillation (AF). However, the precise role of the metabolic syndrome in the development of AF is unknown. METHODS AND RESULTS This prospective, community-based, observational cohort study was based on an annual health check-up program in Japan. We studied 28 449 participants without baseline AF. We used 2 different criteria for the metabolic syndrome--the guidelines of the National Cholesterol Education Program Third Adult Treatment Panel (NCEP-ATP III) and those of the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI)--to study the risk of development of new-onset AF. The metabolic syndrome was present in 3716 subjects (13%) and 4544 subjects (16%) using the NCEP-ATP III and AHA/NHLBI definitions, respectively. During a mean follow-up of 4.5 years, AF developed in 265 subjects (105 women). Among the metabolic syndrome components, obesity (age- and sex-adjusted hazard ratio [HR], 1.64), elevated blood pressure (HR, 1.69), low high-density lipoprotein cholesterol (HR, 1.52), and impaired fasting glucose [corrected] (HR, 1.44 [NCEP-ATP III] and 1.35 [AHA/NHLBI]) showed an increased risk for AF. The association between the metabolic syndrome and AF remained significant in subjects without treated hypertension or diabetes by the NCEP-ATP III definition (HR, 1.78) but not by the AHA/NHLBI definition (HR, 1.28). CONCLUSIONS The metabolic syndrome was associated with increased risk of AF. The metabolic derangements of the syndrome may be important in the pathogenesis of AF.
