Abstract
Our primary objectives are to empirically identify distinct childhood groups based on trajectories of waist circumference (WC) and waist circumference index measurements, and then to estimate associations between these groups and adult diabetes incidence, as well as other outcomes, including blood pressure, body size, body composition, and hemoglobin levels. Childhood WC and height measurements as well as various adult measurements are taken from participants in the Fels Longitudinal Study. Childhood groups are identified using group-based trajectory modeling. Associations between the resulting group probabilities and adult outcomes are examined using mixed models. Our results show that distinct childhood groups are identifiable for both waist size measurements, with growth curves exhibited by these groups becoming distinguishably separate at around 4 years of age. Higher probabilities for groups exhibiting the larger waist size for either measurement were estimated to have higher risks of developing diabetes in adulthood. Associations were also observed between group probabilities and systolic blood pressure, diastolic blood pressure, and various anthropomorphic measurements, with most associations consistently occurring in early adulthood. These findings expand upon the existing literature, showing that childhood trends in waist size, distinguishable at ages as early as 4 years, are associated with adult Type-2 diabetes.

Abstract
Background Studies evaluating the association between abdominal obesity and asthma yielded conflict results. Whether abdominal obesity is positively associated with asthma remains unclear. Objective To quantitatively determine the association between abdominal obesity and asthma. Methods Databases including PubMed, Web of Science, China National Knowledge Infrastructure, China Biology Medicine disc, Chinese Scientific and Technological Journal Database and Wanfang Data were searched up to February 2018 to collect all relevant studies. Reference lists of related articles were also checked. After study selection and data extraction, meta-analysis was conducted to calculate the pooled odds ratio (OR) and corresponding 95% confidence interval (CI). Subgroup analyses by study design and age groups of participants were further performed. Publication bias was assessed via Begg’s rank correlation and Egger’s linear regression methods. Results A total of 13 studies were included in the final meta-analysis, including 2 case–control studies, 6 cohort studies, and 5 cross-sectional studies. Our meta-analysis observed a positive association between abdominal obesity and asthma (OR = 1.47, 95% CI 1.35–1.59). No evidence of heterogeneity (I2 = 10.7%) or publication bias (Begg’s test P = 0.200, Egger’s test P = 0.146) was found. Subgroup analyses by study design and age groups of participants obtained consistently positive results across subgroups. Moreover, our meta-analysis observed similar results when considering this association separately in males and females (Males: OR = 1.37, 95% CI 1.18–1.58; Females: OR = 1.39, 95% CI 1.22–1.58). In addition, the association between abdominal overweight and asthma was further explored in this meta-analysis and the pooled OR and 95% CI was 1.13 (1.03, 1.24), indicating that there is a dose–response relationship between abdominal weight status and asthma. Conclusions Our meta-analysis shows a positive association between abdominal obesity and asthma. Moreover, this association is similar in males and females. In addition, our meta-analysis indicates that there is a dose–response relationship between abdominal weight status and asthma. Therefore, addressing abdominal obesity issue is of great importance. More studies are needed in the future to clarify the association between abdominal obesity and asthma.

Abstract
INTRODUCTION Local guidelines exist in Nelson to assist general practitioners (GPs) in supporting overweight and obese patients with weight loss and improvements in their overall health. This audit measures whether this role is fulfilled in a Very Low Cost Access practice in Nelson, in which 76% of enrolled patients reside in New Zealand social deprivation index quintiles 4 and 5. AIM This study measured whether Nelson Marlborough District Health Board Health Pathways and the Ministry of Health Clinical Guidelines are followed in identifying risk and initiating management, including treatment of additional risk factors, lifestyle modification and dietitian referral. RESULTS Although limited by sample size and consecutive patient screening methodology, the results of this study indicate that overweight and obesity rates in this practice are comparable with the national average, with Māori and Pacific Island populations more likely to be affected compared to their New Zealand European counterparts. Of the patients who had their body mass index recorded, 65% were overweight or obese. Risk factors were assessed and treated in all, green prescriptions were issued in 4%, and 23% were referred to a dietitian. DISCUSSION Audit findings were presented at an intervention session where strategies for improvement were considered including routine waist circumference measurement, dietitian referral, exercise on prescription and providing individualised tailored approaches that integrate patients' cultural and social context. While risk factors are being managed appropriately, improvements can be made in identifying high-risk patients, promoting lifestyle modifications and early dietitian referral.

Central or overall obesity: which one is a better predictor of depressive symptoms in children, adolescents, and youths? Eat Weight Disord 2018; 23:117-123. [PMID: 27653851 DOI: 10.1007/s40519-016-0320-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2016] [Accepted: 09/08/2016] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND PURPOSE Despite the strong effect of central obesity on individuals' physical health outcomes, there is little evidence underlying the relationship between central obesity and mental disorders such as depression, especially in children, adolescents, and youths of the developing countries. This study explores the relationship between depressive symptoms (DS) with central and overall obesity in a sample of Iranian children, adolescents, and youths. METHODS One thousand and fifty-two male participants ranging from 7 to 24 years old underwent standard anthropometry, and filled the DS questionnaire. RESULTS Having controlled the potential confounders (e.g., age, socioeconomic status, pubertal maturation status, and physical activity), we found waist circumference (WC) significantly related to DS in the children (standardized β = 0.14; P < 0.05) and adolescents (standardized β = 0.13; P < 0.05). No significant relationship was observed between WC and DS in the youths (standardized β = 0.09; P = 0.22). In addition, no significant relationship was observed between DS and the percentage of fat in the sampled children (standardized β = 0.085; P = 0.13), adolescents (standardized β = 0.10; P = 0.10), and youths (standardized β = -0.02; P = 0.75). CONCLUSION Central obesity (but not overall obesity) was a significant predictor of DS in the children and adolescents (7-18 years). However, DS in the youths (19-24 years) were not significantly associated with both the central and overall body obesity indices.

Abstract
Background Obesity has been identified as a worldwide epidemic. In China, the highest prevalence of obesity is observed in adults aged ≥45 years old. This study aimed to describe the association between BMI and depressive symptoms among a large representative sample of middle-aged and elderly in China. Method A longitudinal sample of the middle-aged and elderly (6,224 males and 6,883 females) who were interviewed in the 2011 China Health and Retirement Longitudinal Study was used. A multivariate logistic regression analysis was used to examine the effects of socio-demographic characteristics, lifestyle, activity status, health status, physical exercise and body weight on depressive symptoms. Results Approximately 6.94% of the males were underweight, 25.48% were overweight and 8.16% were obese. A higher prevalence of obesity was found among women, with 6.89% being underweight, 31.98% overweight and 14.28% obese. The underweight subjects were more likely to be depressed (odds ratio; OR = 1.30 and 1.19) compared with the normal weight people, respectively, whereas overweight and obese men and women were less likely to be depressed (overweight: OR = 0.76 and 0.80; obesity: OR = 0.64 and 0.65, respectively) than people of normal weight. Conclusion Our data are consistent with the “fat and jolly” hypothesis being valid in both middle-aged and elderly men and women.

Abstract
BACKGROUND Overweight and obesity prevalence has risen dramatically in recent decades. While it is known that overweight and obesity is associated with a wide range of chronic diseases, the cumulative burden of chronic disease in the population associated with overweight and obesity is not well quantified. The aims of this paper were to examine the associations between BMI and chronic disease prevalence; to calculate Population Attributable Fractions (PAFs) associated with overweight and obesity; and to estimate the impact of a one unit reduction in BMI on the population prevalence of chronic disease. METHODS A cross-sectional analysis of 10,364 adults aged ≥18 years from the Republic of Ireland National Survey of Lifestyle, Attitudes and Nutrition (SLÁN 2007) was performed. Using binary regression, we examined the relationship between BMI and the selected chronic diseases. In further analyses, we calculated PAFs of selected chronic diseases attributable to overweight and obesity and we assessed the impact of a one unit reduction in BMI on the overall burden of chronic disease. RESULTS Overweight and obesity prevalence was higher in men (43.0% and 16.1%) compared to women (29.2% and 13.4%), respectively. The most prevalent chronic conditions were lower back pain, hypertension, and raised cholesterol. Prevalence of chronic disease generally increased with increasing BMI. Compared to normal weight persons, the strongest associations were found in obese women for diabetes (RR 3.9, 95% CI 2.5-6.3), followed by hypertension (RR 2.9, 95% CI 2.3-3.6); and in obese men for hypertension (RR 2.1, 95% CI 1.6-2.7), followed by osteoarthritis (RR 2.0, 95% CI 1.2-3.2). Calculated PAFs indicated that a large proportion of chronic disease is attributable to increased BMI, most noticeably for diabetes in women (42%) and for hypertension in men (30%). Overall, a one unit decrease in BMI results in 26 and 28 fewer cases of chronic disease per 1,000 men and women, respectively. CONCLUSIONS Overweight and obesity are major contributors to the burden of chronic disease in the population. The achievement of a relatively modest reduction in average BMI in the population has the potential to make a significant impact on the burden of chronic disease.

Abstract
SUMMARY Obesity has been widely regarded as a public health concern because of its adverse impact on individuals' health. Systematic reviews have been published in examining the effect of obesity on depression, but with major emphasis on general obesity as measured by the body mass index. Despite a stronger effect of abdominal obesity on individuals' physical health outcomes, to our best knowledge, no systematic review was undertaken with regard to the relationship between abdominal obesity and depression. This paper reports the results of a systematic review and meta-analysis of cross-sectional studies examining the relationship between abdominal obesity and depression in a general population. Multiple electronic databases were searched until the end of September 2009. 15 articles were systematically reviewed and meta-analyzed. The analysis showed that the odds ratio of having depression for individuals with abdominal obesity was 1.38 (95% CI, 1.22-1.57) as compared to those who are not obese. Furthermore, it was found that this relationship did not vary with potential confounders including gender, age, measurement of depression and abdominal obesity, and study quality.:

Abstract
BACKGROUND Failure to control for the confounding effects from body perceptions may contribute to the inconsistency of literature on the relationship between body weight and depression. The aim was to determine if perception mediates the associations between measured weight and depression. METHODS We analyzed the data of 13,548 adults age 18 or older, collected in the National Health and Nutrition Examination Survey, 2005-2008. Depression status was ascertained using the Patient Health Questionnaire; and the BMI was calculated from measured height and weight. RESULTS Among women, adjusting for perception weakened the relationship between measured weight and depression. The odds ratios (OR) of depression for being obese and overweight were 2.26 [95% confidence interval (1.50-3.40)] and 1.92 (1.29-2.85) before being adjusted for perception and 1.72 (1.01-2.92) and 1.62 (1.01-2.60) when perception was adjusted for. Independent from measured weight, women who perceived themselves as underweight [OR=2.95(1.47-5.14)] or overweight [1.73 (1.14-2.61)] had an increased odds of depression compared with women who perceived themselves as about the right weight. Among men, measured weight, neither overweight nor underweight, was associated with depression, perceiving oneself as underweight [OR=2.80 (1.42-5.54)] was associated with depression. LIMITATION The inherent limitation of the study's cross-sectional design prevented the authors from investigating causality. CONCLUSION Perception may be more important than measured weight in the relationship with depression. Independent from measured weight either perceived under or overweight among women, or underweight among men, appear to be significantly associated with depression.

Abstract
BACKGROUND Treatment and care of elderly patients with diabetes and hypertension means a hard task in primary care. Patients with these two components of metabolic syndrome are often overweight or obese. Although some parameters of metabolic syndrome are usually measured in a medical setting, checking body weight is usually done by the patients. AIM The aim of this study is to analyse the patients' self-recorded data on weight and compare them according to hypertension and diabetes. PATIENTS AND METHODS Five hundred and forty people (225 men and 315 women) between 60 and 75 years of age were eventually selected in primary care settings. Retrospective self-recorded data on recent weights and every decade since the age of 20, as well as the decade prior to diagnosis were collected. The data of patients with and without diabetes and/or hypertension were compared. RESULTS The current mean body weight was significantly higher in all groups than at the age of 20. Compared with the control group, hypertensive men and women were approximately of the same weight in their twenties and, also, recently, but they gained more weight in the 4th and 5th decades of their life. Diabetics started at higher weights. The greatest weight gain was observed as follows: between 20-30 years and 30-40 years in men and women, respectively, as well as between 50-60 years of age and in the last decade prior to diagnosis in both genders. Weight gain in the control group was steady at a lower rate. CONCLUSIONS Weight gain between 20-40 years of age could be an important factor in the aetiology of diabetes. Stable or at least limited weight gain may be a preventive factor. Considering the limitations of the study, further and decades long epidemiological evaluations are suggested in a larger study population.

Abstract
BACKGROUND Obesity is associated with an increased risk of mental illness; however, evidence linking body mass index (BMI)-a measure of overall obesity, to mental illness is inconsistent. The objective of this study was to examine the association of depressive symptoms with waist circumference or abdominal obesity among overweight and obese U.S. adults. METHODS A cross-sectional, nationally representative sample from the 2005-2006 National Health and Nutrition Examination Survey was used. We analyzed the data from 2,439 U.S. adults (1,325 men and 1,114 nonpregnant women) aged ≥ 20 years who were either overweight or obese with BMI of ≥ 25.0 kg/m2. Abdominal obesity was defined as waist circumference of > 102 cm for men and > 88 cm for women. Depressive symptoms (defined as having major depressive symptoms or moderate-to-severe depressive symptoms) were assessed by the Patient Health Questionnaire-9 diagnostic algorithm. The prevalence and the odds ratios (ORs) with 95% confidence intervals (CIs) for having major depressive symptoms and moderate-to-severe depressive symptoms were estimated using logistic regression analysis. RESULTS After multivariate adjustment for demographics and lifestyle factors, waist circumference was significantly associated with both major depressive symptoms (OR: 1.03, 95% CI: 1.01-1.05) and moderate-to-severe depressive symptoms (OR: 1.02, 95% CI: 1.01-1.04), and adults with abdominal obesity were significantly more likely to have major depressive symptoms (OR: 2.18, 95% CI: 1.35-3.59) or have moderate-to-severe depressive symptoms (OR: 2.56, 95% CI: 1.34-4.90) than those without. These relationships persisted after further adjusting for coexistence of multiple chronic conditions and persisted in participants who were overweight (BMI: 25.0-< 30.0 kg/m2) when stratified analyses were conducted by BMI status. CONCLUSION Among overweight and obese U.S. adults, waist circumference or abdominal obesity was significantly associated with increased likelihoods of having major depressive symptoms or moderate-to-severe depressive symptoms. Thus, mental health status should be monitored and evaluated in adults with abdominal obesity, particularly in those who are overweight.

Abstract
OBJECTIVES To look at the trends in prevalence of generalised (body mass index (BMI) ≥ 25 kg/m2) and abdominal obesity (waist circumference (WC) >102 cm, men; > 88 cm, women) among older people from 1993 to 2008, prevalence of chronic disease by overweight/obesity and WC categories in England 2005 and evaluate the association of these measures with chronic diseases. DESIGN Analyses of nationally representative cross-sectional population surveys, the Health Survey for England (HSE). PARTICIPANTS Non-institutionalised men and women aged ≥ 65 years (in HSE 2005, 1512 men and 1747 women). MEASUREMENTS Height, weight, waist circumference, blood pressure measurements were taken according to standardised HSE protocols. Information collected on socio-demographic, health behaviour and doctor diagnosed health conditions. RESULTS Generalised obesity and abdominal obesity increased among men and women from 1993 to 2008. In 2005, the HSE 2005 focussed on older people. 72% of men and 68% of women aged over 65 were either overweight or obese. Prevalence of raised WC was higher in women (58%) than in men (46%). The prevalence of diabetes and arthritis was higher in people with generalised obesity in both sexes. Men were more likely to have had a joint replacement and had a higher prevalence of stroke if they were overweight only but women were more likely to have had a joint replacement only if they were obese (13%) and had a higher risk of falls with generalised obesity. The pattern was similar for the prevalence of chronic diseases by raised WC. Multivariate analysis showed that generalised and abdominal obesity was independently associated with risk of hypertension, diabetes and arthritis in both men and women. In women only, there was an association between generalised obesity and having a fall in the last year (OR: 1.5), and between abdominal obesity and having a joint replacement (OR: 1.9, p=0.01). CONCLUSION Complications of obesity such as diabetes, hypertension and arthritis, are more common in men and women aged over 65 who are overweight or obese, as well as in those with a raised WC. These conditions impact on morbidity, mortality and have cost implications for the health service and are known to improve with weight loss even in old age. Treatment strategies to address these conditions such as weight management and prevention of overweight and obesity are important even in older people. There is a need to ensure that older people are given appropriate advice about keeping physically active and eating sensibly.

Abstract
There is currently no consensus regarding the optimal protocol for measurement of waist circumference (WC), and no scientific rationale is provided for any of the WC protocols recommended by leading health authorities. A panel of experts conducted a systematic review of 120 studies (236 samples) to determine whether measurement protocol influenced the relationship of WC with morbidity of cardiovascular disease (CVD) and diabetes and with mortality from all causes and from CVD. Statistically significant associations with WC were reported for 65% (152) of the samples across all outcomes combined. Common WC protocols performed measurement at the minimal waist (33%), midpoint (26%) and umbilicus (27%). Non-significant associations were reported for 27% (64) of the samples. Most of these protocols measured WC at the midpoint (36%), umbilicus (28%) or minimal waist (25%). Significant associations were observed for 17 of the remaining 20 samples, but these were not significant when adjustment was made for covariates. For these samples, the most common WC protocols were the midpoint (35%) and umbilicus (30%). Similar patterns of association between the outcomes and all WC protocols were observed across sample size, sex, age, race and ethnicity. Our findings suggest that WC measurement protocol has no substantial influence on the association between WC, all-cause and CVD mortality, CVD and diabetes.

Abstract
BACKGROUND Obesity is a well-known cause of cardiovascular disease burden and premature death, but effects on psychological morbidity remain uncertain. This article reports findings following a systematic review of epidemiological studies to determine whether obesity causes depression. METHODS Multiple databases were searched for English-language studies of etiology of obesity (exposure variable, analyzed as an ordered category) on depression outcomes (dependent variables, continuous or categorical). Studies in children and in women during pregnancy or postpartum were excluded, as were nonrepresentative cross-sectional studies. Searches and identification of studies for inclusion were performed by EA, whereas a descriptive synthesis of important study characteristics was undertaken independently by us. RESULTS We reviewed 24 out of approximately 4500 potentially relevant studies; 4 were prospective cohort studies and 20 were cross-sectional studies (10 from the United States). Effect measures reported in all prospective cohort studies were consistent and suggested that obesity may increase the odds of future depression outcomes (symptoms or nonclinical diagnosis of depression). Effect measures reported in most cross-sectional studies from the United States supported the hypothesized association between obesity and prevalence of depression outcomes for women but not men, in contrast most cross-sectional studies from populations other than the United States consistently failed to find such associations. CONCLUSIONS Overall, there is a weak level of evidence supporting the hypothesis that obesity increases the incidence of depression outcomes. Few high-quality prospective cohort studies exist, and cross-sectional studies account for the vast body of published evidence, and therefore firm conclusions for causality cannot yet be drawn. Our finding warrants additional high-quality etiological research on this topic.

Abstract
The purpose of this study was to examine the associations between smoking, physical inactivity, obesity, and asthma severity among US adults. The magnitude of these associations was very strong. For example, those who visited an emergency room in the past year were 60% more likely than those who did not to smoke; those who used an inhaler > or =15 times in the past month (versus those who did not use an inhaler) were 90% more likely to be physically inactive; and those who had asthma symptoms all the time in the past 30 days (versus those with no symptoms) were 80% more likely to be obese.

Abstract
PURPOSE OF REVIEW Childhood asthma and obesity are significant public health problems. The prevalence of both disorders has increased considerably in the past decade. This review will highlight recent publications regarding the nature of the relationship between asthma and obesity and the clinical effects of obesity in children with asthma. RECENT FINDINGS Most prospective studies suggest that obesity increases the risk of subsequent asthma. Possible mechanisms for the relationship between asthma and obesity include airway inflammation, mechanical changes associated with obesity, changes in airway hyper-responsiveness, and changes in physical activity and diet. Most studies suggest that obesity increases the clinical severity of asthma and decreases quality of life in children with asthma. More research is required to further define and clarify the relationship between asthma and obesity in children. SUMMARY There are many questions and few answers regarding the relationship between asthma and obesity in children. Additional studies are needed to clarify the relationship between the two epidemics so that effective interventions can be developed to improve the health and lives of children with both asthma and obesity.

Abstract
BACKGROUND Obesity is a well-known cause of cardiovascular disease burden and premature death, but effects on depressive symptoms remain equivocal. Depressive symptoms may be more common among the obese individuals who perceive themselves as overweight, rather than those who perceive themselves as having an acceptable weight. Our aim was to determine whether weight status and weight perceptions are independently associated with psychological distress. METHODS We conducted a cross-sectional study using data from the Australian National Health Survey 2004-2005 (N=17 253). All variables were collected by self-report. Adjusted multinomial logistic regression analysis was conducted to generate prevalence odds ratios with 95% confidence intervals (95% CI) for medium (Kessler Psychological Distress Scale (K10) scores of 20-29) and high (K10 scores of 30-50) psychological distress (compared with K10 scores of 10-19 as the reference) associated with weight status (standard body mass index (BMI) cutoffs for underweight, overweight and obesity vs normal weight), weight perception (perceived underweight and overweight vs acceptable weight) and weight misperception (incorrect with BMI vs correct with BMI) adjusting for numerous important covariates. RESULTS Overweight and underweight perception increased the odds of medium (40 and 50%) and high (50 and 120%) psychological distress, whereas weight status and weight misperception were not associated with psychological distress in adjusted analysis. Gender, alcohol consumed per week and post-school education were not significant covariates (at P<0.10 level). CONCLUSIONS Overweight and underweight perception rather than weight status or weight misperception are significant risk factors associated with medium and high psychological distress prevalence and effects appear to be uniform for men and women. Well-designed prospective studies are still needed to determine whether weight perceptions cause psychological distress, and if so, whether symptoms are significantly reduced following effective intervention.

Abstract
BACKGROUND Physical inactivity and insufficient fruit and vegetable consumption are key risk factors for obesity and noncommunicable diseases. Weight perceptions may affect physical activity and diet behaviors. We report current prevalence estimates of Australian adults meeting recommended levels of leisure-time physical activity (LTPA) (> or =150 min/week or more of at least moderate-intensity physical activity (including walking) on > or =5 days/week) and fruit (> or =2 servings/day) and vegetable (> or =5 servings/day) consumption for health benefits, by weight status and perceptions. METHODS We conducted a cross-sectional survey analysis of data for 16 314 adults from the Australian National Health Survey 2004-2005. All variables were collected by self-report. Weighted estimates were age- and gender-specific, and data were analyzed using logistic regression with acceptable weight referent categories, adjusting for covariates. RESULTS Among acceptable, overweight and obese adults, the prevalence of LTPA was 26.8, 26.1 and 19.3% for men, and 27.7, 23.7 and 19.7% for women, respectively. Approximately 55 and 15% of adults consumed sufficient fruit servings/day and vegetable servings/day, respectively, and less than 5% of adults met combined LTPA and diet guidelines. Overweight decreased the odds ratio for LTPA among women but not men, and obesity decreased the odds ratio for LTPA among both men and women. Overweight perception conferred odds ratios of 0.83 (95% CI 0.70-0.97, P=0.021) for overweight men, and of 0.74 (95% CI 0.62-0.88, P=0.001) and 0.69 (95% CI 0.59-0.80, P<0.001) for obese men and women, respectively; for LTPA, whereas no significant associations were found for acceptable weight perception. No consistent associations between weight status or perceptions and diet behaviors were found. CONCLUSIONS Overweight perception may be another barrier to physical activity participation among men and women with excess body weight. Public health strategies might need to focus on overcoming weight perception as well as weight status barriers to adopting healthy physical activity behaviors.
