Abstract
BACKGROUND The COVID-19 pandemic has significantly reduced physical activity (PA) levels and increased sedentary behavior (SB), which can lead to worsening physical fitness (PF). Children and adolescents may benefit from mobile health (mHealth) apps to increase PA and improve PF. However, the effectiveness of mHealth app-based interventions and potential moderators in this population are not yet fully understood. OBJECTIVE This study aims to review and analyze the effectiveness of mHealth app-based interventions in promoting PA and improving PF and identify potential moderators of the efficacy of mHealth app-based interventions in children and adolescents. METHODS We searched for randomized controlled trials (RCTs) published in the PubMed, Web of Science, EBSCO, and Cochrane Library databases until December 25, 2023, to conduct this meta-analysis. We included articles with intervention groups that investigated the effects of mHealth-based apps on PA and PF among children and adolescents. Due to high heterogeneity, a meta-analysis was conducted using a random effects model. The Cochrane Risk of Bias Assessment Tool was used to evaluate the risk of bias. Subgroup analysis and meta-regression analyses were performed to identify potential influences impacting effect sizes. RESULTS We included 28 RCTs with a total of 5643 participants. In general, the risk of bias of included studies was low. Our findings showed that mHealth app-based interventions significantly increased total PA (TPA; standardized mean difference [SMD] 0.29, 95% CI 0.13-0.45; P<.001), reduced SB (SMD -0.97, 95% CI -1.67 to -0.28; P=.006) and BMI (weighted mean difference -0.31 kg/m2, 95% CI -0.60 to -0.01 kg/m2; P=.12), and improved muscle strength (SMD 1.97, 95% CI 0.09-3.86; P=.04) and agility (SMD -0.35, 95% CI -0.61 to -0.10; P=.006). However, mHealth app-based interventions insignificantly affected moderate to vigorous PA (MVPA; SMD 0.11, 95% CI -0.04 to 0.25; P<.001), waist circumference (weighted mean difference 0.38 cm, 95% CI -1.28 to 2.04 cm; P=.65), muscular power (SMD 0.01, 95% CI -0.08 to 0.10; P=.81), cardiorespiratory fitness (SMD -0.20, 95% CI -0.45 to 0.05; P=.11), muscular endurance (SMD 0.47, 95% CI -0.08 to 1.02; P=.10), and flexibility (SMD 0.09, 95% CI -0.23 to 0.41; P=.58). Subgroup analyses and meta-regression showed that intervention duration was associated with TPA and MVPA, and age and types of intervention was associated with BMI. CONCLUSIONS Our meta-analysis suggests that mHealth app-based interventions may yield small-to-large beneficial effects on TPA, SB, BMI, agility, and muscle strength in children and adolescents. Furthermore, age and intervention duration may correlate with the higher effectiveness of mHealth app-based interventions. However, due to the limited number and quality of included studies, the aforementioned conclusions require validation through additional high-quality research.

Abstract
This paper presents a shape classification scheme for the female torso, based on anthropometric measurements and 3D body scans from a large scale anthropometric survey. The ability to classify the female body shape is highly desired by the clothing industry and apparel researchers for improving pattern design and fit. In order to objectively classify female torso shapes, we employed principal component analysis on torso related anthropometric measurements and three-dimensional (3D) torso surface data to identify the most dominant measurements. The principal component analysis of the anthropometric measurements show that Waist Circumference is the most dominant variable to define overall female torso size, and that Chest-Waist Drop and Waist-Buttock Drop jointly define the local shape of the torso. Using these findings, a torso shape classification scheme was developed, where nine shape categories were defined from Chest-Waist Drop and Waist-Buttock Drop while torso sizes were divided by Waist Circumference. The distribution of nine shape categories is dependent on the value of Waist Circumference. Mean shape of each shape category was then generated from 3D scans.

Abstract
BACKGROUND The popularity of noninvasive body contouring procedures has been steadily increasing in recent years, however, studies evaluating its effectiveness in individuals with overweight range body mass index (BMI) are limited. OBJECTIVE To evaluate the efficacy and safety of combined 2 MHz radiofrequency (RF) and electrical multidirectional stimulation (EMDS) for the improvement of the abdominal contour in subjects with overweight range BMI. METHODS Twelve participants with overweight range BMI (23.6-24.9 kg/m2 ) underwent a single RF treatment, followed by a series of six EMDS treatments. Follow-up assessments (abdominal circumference [AC] and skinfold thickness measurements) were scheduled 1, 2, and 3 months after the final session. RESULTS At 1 month after the final treatment, a 3.1% (2.6 ± 0.47 cm, mean ± SD) significant reduction in mean AC was observed (p ˂ 0.001) and a maximal skinfold thickness reduction of 14% (4.6 ± 1.1 mm) was also noted (p = 0.032). Transient dysesthesia lasting 2-3 hours after EMDS treatment was the most common adverse effect reported by 5 of 12 subjects (41.7%), with no other serious side effects. CONCLUSIONS Combined RF and EMDS treatments are safe and effective, yielding significant reductions in both AC and skinfold thickness in patients with overweight range BMI, causing only minimal and transient adverse effects.

Abstract
Aim: Obesity is a known risk factor for cardiovascular diseases. However, there are also studies showing that increased body mass index is unexpectedly protective in myocardial infarction. More studies are needed to elucidate this situation, known as the obesity paradox. This study was conducted to investigate the relationship between waist circumference and mortality and morbidity in acute ST elevated myocardial infarct (STEMI).
Material and Method: This is a prospective and observational study. Patients diagnosed with STEMI on electrocardiography (ECG) were included in the study. Immediately after the exhalation, waist circumference (WC) was measured on a horizontal plane at a point equidistant from the lowest floating rib and the upper border of the iliac crest. The role of waist circumference in the development of mortality and major cardiac events within 1 month was evaluated.
Results: A total of 106 patients admitted to the emergency department with STEMI were included in the study. While increased waist circumference was associated with mortality, it was insignificant in terms of major adverse cardiovascular event (MACE) development. Low BMI is significant in terms of decreased mortality and MACE.
Conclusions: The use of WC as an indicator of body fat ratio rather than weight in STEMI may be more valuable in the evaluation of mortality and MACE.

Abstract
BACKGROUND Obesity is associated with adverse health events among diabetic patients, however, the relationship between obesity fluctuation and risk of microvascular complications among this specific population is unclear. We aimed to examine the effect of waist circumference (WC) and body mass index (BMI) variability on the risk of diabetic microvascular outcome. METHODS Annually recorded anthropometric data in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study was used to examine the association of WC and BMI variability defined as variability independent of mean, with the risk of microvascular outcomes, including neuropathy, nephropathy, and retinopathy. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) (Trial registration: ClinicalTrials.gov., no. NCT00000620). RESULTS There were 4,031, 5,369, and 2,601 cases of neuropathy, nephropathy, and retinopathy during a follow-up period of 22,524, 23,941, and 23,850 person-years, respectively. Higher levels of WC and BMI variability were associated with an increased risk of neuropathy. Compared with the lowest quartile, the fully-adjusted HR (95% CI) for the highest quartile of WC and BMI variability for neuropathy risk were 1.21 (1.05 to 1.40) and 1.16 (1.00 to 1.33), respectively. Also, higher quartiles of BMI variability but not WC variability were associated with increased risk of nephropathic events. The fully-adjusted HR (95% CI) for the highest quartile compared with the lowest quartile of BMI variability was 1.31 (1.18 to 1.46). However, the results for retinopathic events were all insignificant. CONCLUSION Among participants with type 2 diabetes mellitus, WC and BMI variability were associated with a higher risk of neuropathic events, whereas BMI variability was associated with an increased risk of nephropathic events.

Abstract
Background It is not certain whether non-alcoholic fatty liver disease (NAFLD) or abdominal obesity (AO) has stronger associations with atherosclerosis and coronary artery disease (CAD) risk across different genders. The purpose of this study was to determine the gender-based association of NAFLD and AO with subclinical atherosclerosis represented by coronary artery calcification (CAC) and CAD risk by Framingham risk score (FRS). Methods A total of 1,655 participants in a health-screening program (mean age: 49.44 years; males: 70.33%) were enrolled for analysis. Fatty liver and coronary artery calcium score (CACS) were measured via ultrasonography (US) and multi-detector computed tomography (MDCT). The presence of CAC was defined as having a CACS > 0, intermediate to high CAD risk was defined as FRS ≥ 10%, while the presence of AO was defined as having a waist circumference (WC) of ≥90 cm for men and ≥80 cm for women. Participants were categorized into four groups depending on the presence or absence of NAFLD and/or AO. Results The percentage of subjects with CACS > 0 was highest in the AO-only group (overall: 42.6%; men: 48.4%; women: 35.8%); and FRS ≥ 10% was highest in the group with both abnormalities (overall: 50.3%%; men: 57.3%; women: 32.4%). After adjustment factors, the odds ratio (OR) for CAC and FRS was the highest in the group with both abnormalities [men: 1.61 (1.13–2.30) for CACS > 0 and 5.86 (3.37–10.20) for FRS ≥ 10%; women: 2.17 (1.13–4.16) for CACS > 0 and 6.31 (2.08–19.10) for FRS ≥ 10%]. In men, the OR of NAFLD was higher than that of AO [1.37 (1.03–1.83) vs. 1.35 (1.02–1.79) for CACS > 0, 3.26 (2.13–4.98) vs. 2.97 (1.91–4.62) for FRS ≥ 10%]. However, women with AO consistently showed increased OR for CACS > 0 [1.87 (1.11–3.16)] and FRS ≥ 10% [4.77 (2.01–11.34)]. Conclusion The degree of association of NAFLD and AO with CAC and FRS depends on the gender. NAFLD is more closely associated with CACS > 0 and FRS ≥ 10% in men and AO in women, respectively. NAFLD and AO could be considered independent determinants of CAC and FRS by gender.

Abstract
A considerable chronic disease burden existed in people with normal body mass index (BMI), it is imperative to study the prevailing trends in abdominal obesity among Chinese people with normal BMI. Hence, we aimed to analyze updated prevalence data on abdominal obesity trends among Chinese adults with a normal BMI. We used data from the China Health and Nutrition Survey (CHNS) conducted between 1993 and 2015. Abdominal obesity is defined as waist circumference (WC) ≥ 90 cm for men and ≥ 80 cm for women following the International Diabetes Federation recommendations for Asians. Over the 23-year period, the age-standardized mean WC values showed a significant increasing trend among Chinese adults with BMI < 25 kg/m2, with the mean value increased from 74.0 cm to 78.5 cm (P for trend < 0.0001). During the period of 1993-2015, the age-standardized prevalence of abdominal obesity increased from 12.1 to 26.0% (P for trend < 0.0001). Significant increases were observed in both sexes, all age groups, rural and urban residents, and all educational attainment groups (all P for trends < 0.0001), with a greater relative increase noted among men, younger participants, and rural residents. Similar significant trends were noted when a more stringent BMI < 23 kg/m2 cut point (Asian cut point) was applied. A low magnitude of overlap existed between abdominal obesity and general obesity, irrespective of the criteria used. The mean WC and the prevalence of abdominal obesity among Chinese adults with normal BMI increased continuously from 1993 to 2015. The upward trends were noted in both sexes, all age groups, rural and urban regions, and all educational attainment groups. Our estimates emphasize the importance of adding WC in addition to BMI as measures to monitor obesity prevalence.

Abstract
BACKGROUND Prior studies have established inconsistent associations between body weight and mental health. However, most work has relied on body mass index (BMI) and examination of a single mental health variable. The present study examined associations of BMI and waist circumference with multiple mental health variables in a transdiagnostic psychiatric sample. METHODS Nursing staff measured waist circumference and calculated the BMI of 742 adults (54.6% female, 45.4% male) presenting for psychiatric treatment. Participants completed the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), Behavior and Symptom Identification Scale (BASIS-24), and Mental Health Continuum-Short Form (MHC-SF) as part of standard clinical monitoring. Suicide risk was assessed using the clinician-administered Mini International Neuropsychiatric Interview (M.I.N.I.). For curve fit estimation regression models, we entered BMI and waist circumference as independent variables separately; we entered seven dependent variables separately: 1) depression, 2) anxiety, 3) substance use, 4) self-harm, 5) interpersonal functioning, 6) well-being, and 7) suicide risk. RESULTS Increased BMI was associated with decreased well-being and increased depression. Increased waist circumference was associated with worse interpersonal functioning. Non-linear (quadratic) associations were observed between weight and depression, substance use, self-harm, and suicide. LIMITATIONS Most of the sample was White and only 2.6% was in the underweight category, limiting broad applicability of findings. Cross-sectional design precludes causal attributions. CONCLUSIONS Given associations between well-being, depression, interpersonal functioning, substance use, self-harm, and suicide with weight, findings may be used to inform mental health treatment, particularly by tailoring interventions to high-risk weight categories (underweight, obese) in psychiatric populations.

Abstract
The purpose of this study was to compare obesity classification methods (body mass index (BMI)), abdominal girth (AG), and body fat percentage (BF%)), among college students. College students (n=5943) completed an objective fitness assessment, where height and weight (used to calculate BMI), AG, and BF% (using Bioelectrical Impedance Analysis) were assessed. Correlation and chi-square tests for independence analyses examined relationships between variables and obesity classification methods; and, the sensitivity and specify of BMI using AG and BF% were calculated. Significant correlations were found between BMI and BF% for men (r=0.775, p<0.001) and women (r=0.849, p<0.001); BMI and AG for men (r=0.868, p<0.001) and women (r=0.858, p<0.001); and, BF% and AG for men (r=0.749, p<0.001) and women (r=0.767, p<0.001). There were significant associations between BMI, AG, and BF% for both sexes. Obesity categorization differed significantly between methods. In men and women, respectively, 47.6% and 44.1% classified as normal weight based on BF% were classified as overweight or obese based on BMI (Men: χ2=1547, p<0.001; Women: χ2=1127, p<0.001). In men and women, respectively, 48.3% and 24.0% classified as normal based on AG were classified as overweight or obese using BMI (Men: χ2=1274, p<0.001; Women: χ2=996, p<0.001). Comparing AG and BF%, 25.1% of men and 18.6% of women classified as normal based on AG were classified as overweight or obese using BF% (Men: χ2=1412, p<0.001; Women: χ2=421, p<0.001). Obesity classification differed significantly between methods, and BMI demonstrated relatively poor predictive value with respect to obesity classification. Thus, caution should be applied when using BMI to diagnose obesity among college students.

Abstract
Diet quality influences glycemic control in people with type 2 diabetes (T2D), impacting their risk of complications. While there are many cross-sectional studies of diet and diabetes, there is little understanding of the extent to which people with T2D change their diet after diagnosis and of the factors that impact those changes. This paper describes the rationale for and design of the 3D longitudinal Study which aims to: (i) describe diet quality changes in the 12 months following T2D diagnosis, (ii) identify the demographic, physical and psychosocial predictors of sustained improvements in diet quality and glycemic control, and (iii) identify associations between glycemic control and diet quality in the 12 months following diagnosis. This cohort study will recruit adults registered with the Australian National Diabetes Services Scheme who have been recently diagnosed with T2D. Participants will be involved in five purposefully developed telephone surveys, conducted at 3 monthly intervals over a 12-month period. Diet quality will be determined using a 24-h dietary recall at each data collection point and the data will be scored using the Dietary Approaches to Stop Hypertension (DASH) diet-quality tool. This study is the first dedicated to observing how people newly diagnosed with T2D change their diet quality over time and the predictors of sustained improvements in diet and glycemic control.

Abstract
OBJECTIVE The aim of this prospective study was to compare scrotal ultrasonographic findings in obese and normal weight infertile men and correlate these findings with semen parameters and hormonal profile. MATERIAL AND METHODS A total of 188 men presented for infertility evaluation were included in this study. They were divided according to body mass indices into obese (n=96) and normal weight infertile patients (n=92). Basic infertility evaluation, semen analysis and scrotal duplex ultrasound examination in addition to measurement of serum levels of follicular stimulating hormone, testosterone and estradiol were done for all cases. The ratio between testicular size measured by scrotal ultrasound and body mass index were calculated. RESULTS Any significant differences were not observed in semen parameters, serum levels of follicular stimulating hormone and testosterone between obese and normal weight infertile men (p>0.05). Serum estradiol level was significantly higher in obese than normal weight infertile men (p<0.001). There is significant increase in subclinical varicocele, hydrocele and testicular microlithiasis detected by scrotal ultrasound in obese infertile men than nonobese patients (p<0.05). Despite having comparable testicular size detected on scrotal ultrasound, infertile obese men had significantly lower total testicular volume to body mass index ratio and this ratio correlated positively with semen volume, sperm concentration, total sperm count and serum testosterone but negatively with serum follicular stimulating hormone and estradiol levels. CONCLUSION We therefore conclude that the incidence of subclinical varicocele, hydrocele and testicular microlithiasis was higher in obese infertile patients and the ratio between testicular volume assessed by scrotal ultrasound and body mass index may be a new parameter that correlates with subfertility status in these men.

Abstract
Body mass index (BMI) and waist circumference (WC) have limitations in stratifying cardio-metabolic risks. Another obesity measure, A Body Shape Index (ABSI), has been introduced but its applicability remains limited. To address this, the z-score of the log-transformed ABSI (LBSIZ) was recently developed. This study aimed to examine the ability of LBSIZ, compared to that of WC and BMI, to predict cardiovascular disease (CVD) risk. The study included 8,485 participants aged 40-69 years (mean age = 52.1) who were followed for 10 years and recruited from the Korean Genome and Epidemiology Study, a population-based cohort study. The area under the curve was 0.635 (95% confidence interval [CI]: 0.614-0.657) for LBSIZ, 0.604 (95%CI: 0.580-0.627) for WC, and 0.538 (95%CI: 0.514-0.562) for BMI. The AUC of the Framingham risk score (FRS) was 0.680 (95%CI: 0.659-0.701) in comparison. When we added LBSIZ to the model, the integrated AUC significantly improved from 0.680 to 0.692 (95%CI: 0.672-0.713; p value, 0.033), whereas there were no changes with BMI (AUC, 0.678; 95%CI: 0.656-0.699) or WC (AUC, 0.679; 95%CI: 0.658-0.701). In the multivariate Cox regression analysis, LBSIZ but not BMI or WC showed a significant hazard ratio of CVD event compared to 1st decile of each parameter. In the restricted cubic spline regression, BMI and WC showed an overall J-shaped relationship with CVD events whereas LBSIZ showed a linear relationship. LBSIZ is strongly associated with CVD risk and should predict CVD risk better than BMI and WC in the general population.

Abstract
Background Metabolic Syndrome (MetS) refers to a cluster of metabolic disturbances which is associated with increased risk for vascular and degenerative conditions in general population. Although the relationship between vascular risk factors and dementia is undisputable, additional hazard for cognitive decline in older population with concurrent metabolic disorders still waits to be demonstrated. The present review aims to analyze data on MetS and risk for cognitive decline in elderly persons. Methods Database searches were performed in Medline, ISI and PsycINFO for articles assessing cognitive performances of older subjects with MetS. Results Of a total of 505 studies, 25 were selected for the review. Risk of selection biases was identified in all the studies. Although all articles followed recognized diagnostic recommendations for MetS, minor criteria modifications were detected in most of them. Hyperglycemia was consistently associated with impaired cognitive performances in older individuals, but the role of MetS for cognitive decline and for the onset of dementia showed heterogeneous results. Discussion Current available data in the literature concerning the impact of MetS on the cognition of older population is inconclusive and based on inconsistent evidence. Differential effects of individual MetS components and factors associated with the age of the sample may have accounted for divergent findings among articles, but larger and higher quality studies in this field are still needed.

Abstract
Many antipsychotics promote weight gain, which can lead to non-compliance and relapse of psychosis. By developing models that accurately identify individuals at greater risk of weight gain, clinicians can make informed treatment decisions and target intervention measures. We examined clinical, genetic and expression data for 284 individuals with psychosis derived from a previously published randomised controlled trial (IMPACT). These data were used to develop regression and classification models predicting change in Body Mass Index (BMI) over one year. Clinical predictors included demographics, anthropometrics, cardiac and blood measures, diet and exercise, physical and mental health, medication and BMI outcome measures. We included genetic polygenic risk scores (PRS) for schizophrenia, bipolar disorder, BMI, waist-hip-ratio, insulin resistance and height, as well as gene co-expression modules generated by Weighted Gene Co-expression Network Analysis (WGCNA). The best performing predictive models for BMI and BMI gain after one year used clinical data only, which suggests expression and genetic data do not improve prediction in this cohort.

Abstract
BACKGROUND: Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results. OBJECTIVES: In this study we aimed to investigate the frequency of androgenetic alopecia, the presence of accompanying systemic diseases, the relation between body mass index and androgenetic alopecia severity and the association of hyperandrogenemia signs with androgenetic alopecia in patients who referred to our outpatient clinic. METHODS: Patients who referred to our clinic between October 2013 and May 2014 were included in the study. Diagnosis of androgenetic alopecia was made upon clinical findings. Presence of seborrhea and acne in both genders, and hirsutism in women, were examined. Age, gender, smoking habit and alcohol consumption, age of onset of androgenetic alopecia, family history, accompanying systemic diseases and abnormalities of menstrual cycle were recorded. RESULTS: 954 patients (535 women, 419 men) were included in the study. Androgenetic alopecia prevalence found was 67.1% in men and 23.9% in women. Androgenetic alopecia prevalence and severity were correlated with age in both genders (p=0,0001). Frequency of accompanying systemic diseases were not significantly different between patients with and without androgenetic alopecia (p=0,087), except for hypertension, which was significantly more frequent in men with androgenetic alopecia aged between 50 and 59 years. Study limitations: Despite the exclusion of other causes of alopecia, differentiation of Ludwig grade 1 AGA from telogen effluvium based on clinical features alone is difficult. CONCLUSIONS: In our study the rate of androgenetic alopecia was found to be higher than the other studies made in Asian and Caucasian populations.

Abstract
Delayed onset muscle soreness (DOMS) occurs within 1-2 days after eccentric exercise, but the mechanism mediating hypersensitivity is unclear. This study hypothesized that eccentric exercise reduces the blood flow response following muscle contractions and cuff occlusion, which may result in accumulated algesic substances being a part of the sensitization in DOMS. Twelve healthy subjects (five women) performed dorsiflexion exercise (five sets of 10 repeated eccentric contractions) in one leg, while the contralateral leg was the control. The maximal voluntary contraction (MVC) of the tibialis anterior muscle was recorded. Blood flow was assessed by ultrasound Doppler on the anterior tibialis artery (ATA) and within the anterior tibialis muscle tissue before and immediately after 1-second MVC, 5-seconds MVC, and 5-minutes thigh cuff occlusion. Pressure pain thresholds (PPTs) were recorded on the tibialis anterior muscle. All measures were done bilaterally at day 0 (pre-exercise), day 2, and day 6 (post-exercise). Subjects scored the muscle soreness on a Likert scale for 6 days. Eccentric exercise increased Likert scores at day 1 and day 2 compared with day 0 (P<.001). Compared with pre-exercise (day 0), reduced PPT (~25%, P<.002), MVC (~22%, P<.002), ATA diameter (~8%, P<.002), ATA post-contraction/occlusion blood flow (~16%, P<.04), and intramuscular peak blood flow (~23%, P<.03) were found in the DOMS leg on day 2 but not in the control leg. These results showed that eccentric contractions decreased vessel diameter, impaired the blood flow response, and promoted hyperalgesia. Thus, the results suggest that the blood flow reduction may be involved in the increased pain response after eccentric exercise.

Abstract
INTRODUCTION We aimed to determine the risk factors associated with abdominal obesity (AO) in suburban adolescents. METHODS This cross-sectional study included adolescents aged 15-17 years from five randomly selected secondary schools in the Hulu Langat district of Selangor state, Malaysia. Waist circumference (WC) was measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest. Information on sociodemographic data, dietary habits, physical activity levels and duration of sleep was obtained via interviewer-administered questionnaires. Participants' habitual food intake was determined using a 73-item Food Frequency Questionnaire. RESULTS Among 832 participants, 56.0% were girls; 48.4% were Malay, 40.5% Chinese, 10.2% Indian and 0.8% of other ethnic groups. Median age and WC were 16 (interquartile range [IQR] 15-16) years and 67.9 (IQR 63.0-74.6) cm, respectively. Overall prevalence of AO (> 90th percentile on the WC chart) was 11.3%. A higher proportion (22.4%) of Indian adolescents were found to have AO compared with Malay and Chinese adolescents. Logistic regression analysis showed that female gender (adjusted odds ratio [OR] 7.064, 95% confidence interval [CI] 2.087-23.913; p = 0.002), Indian ethnicity (adjusted OR 10.164, 95% CI 2.182-47.346; p = 0.003), irregular meals (adjusted OR 3.193, 95% CI 1.043-9.774; p = 0.042) and increasing body mass index (BMI) (adjusted OR 2.867, 95% CI 2.216-3.710; p < 0.001) were significantly associated with AO. CONCLUSION AO was common among Malaysian adolescents. Female gender, Indian ethnicity, irregular meals and increasing BMI were significant risk factors.

Abstract
BACKGROUND Fatigue is a multifactorial condition that leads to disease and loss in production, and it affects a large number of workers worldwide. This study aims to demonstrate a resistance exercise protocol that individuals will perform during the work schedule, and to evaluate the effectiveness of this exercises program for fatigue control. METHODS/DESIGN This is a cluster randomized controlled trial with two arms and is assessor blinded. A total of 352 workers of both sexes, aged 18-65 years, from a medium-sized dairy plant were enrolled in this study. Participants will be recruited from 13 production sectors according to the eligibility criteria and will be randomized by clusters to either the Progressive Resistance Exercise (PRE) intervention group or the Compensatory Workplace Exercise (CWE) comparative group. A resistance exercise program will be implemented for both groups. The groups will receive instructions on self-management, breaks, adjustments to workstations, and the benefits of physical exercise. The PRE group will perform resistance exercises with gradual loads in an exercise room, and the CWE group will perform exercise at their workstations using elastic bands. The exercise sessions will be held 3 times a week for 20 min. The primary outcome measures will be symptoms of physical and mental fatigue, and muscular fatigue based on a one-repetition maximum (1RM). The secondary outcome measures will be level of physical activity, musculoskeletal symptoms, physical condition, perceived exposure, and productivity. The workers will be assessed at baseline and after a 4-month program. A linear mixed model will be applied on an intention-to-treat basis. DISCUSSION This intervention is expected to reduce symptoms of fatigue in the workers. The exercise program is indicating in the workplace, although there are few studies describing the effects of exercise on the control of fatigue in the workplace. Emphasis will be placed on adherence to the program, which may result in significant and clinically important reductions in fatigue. It is also expected that the findings of this study will contribute significantly to the decision-making capacity of professionals working in the field of occupational health.

Abstract
PURPOSE Although waist circumference can provide important metabolic risk information, logistic issues inhibit its routine use in outpatient practice settings. We assessed whether self-measured waist circumference is sufficiently accurate to replace professionally measured waist circumference for identifying high-risk patients. METHODS Medical outpatients and research participants self-measured their waist circumference at the same visit during which a professionally measured waist circumference was obtained. Participants were provided with standardized pictorial instructions on how to measure their waist circumference, and professionals underwent standard training. RESULTS Self- and professionally measured waist circumference data were collected for 585 women (mean ± SD age = 40 ± 14 years, mean ± SD body mass index = 27.7 ± 6.0 kg/m(2)) and 165 men (mean ± SD age = 41 ± 14 years, mean ± SD body mass index = 29.3 ± 4.6 kg/m(2)). Although self- and professionally measured waist circumference did not differ significantly, we found a clinically important false-negative rate for the self-measurements. Eleven percent of normal-weight and 52% of overweight women had a professionally measured waist circumference putting them in a high-risk category for metabolic syndrome (ie, greater than 88 cm); however, 57% and 18% of these women, respectively, undermeasured their waist circumference as falling below that cutoff. Fifteen percent and 84% of overweight and class I obese men, respectively, had a professionally measured waist circumference putting them in the high-risk category (ie, greater than 102 cm); however, 23% and 16% of these men, respectively, undermeasured their waist circumference as falling below that cutoff. CONCLUSIONS Despite standardized pictorial instructions for self-measured waist circumference, the false-negative rate of self-measurements approached or exceeded 20% for some groups at high risk for poor health outcomes.

Abstract
BACKGROUND Obesity is a well-established risk factor for cardiovascular disease, diabetes, hyperlipidemia, hypertension, osteoarthritis, and stroke. Stimulants, such as ephedrine and caffeine and their herbal counterparts, have proved effective in facilitating body weight loss, but their use is controversial due to their undesired effects. Other nutraceuticals have shown moderate success in reducing body weight, whereas several other compounds have demonstrated little or no effect. Therefore, a tolerable and effective nutraceutical that can increase energy expenditure and/or decrease caloric intake is desirable for body weight reduction. OBJECTIVE The primary purpose of this study was to assess the tolerability and effectiveness of a novel, stimulant-free, dietary supplement containing glucomannan, chitosan, fenugreek, Gymnema sylvestre, and vitamin C on body weight and fat loss and change in body composition in obese adults. METHODS In this single-center, prospective, randomized, double-blind, placebo-controlled study conducted at the University of Guelph (Guelph, Ontario, Canada), obese adults (aged 20-50 years; body mass index [BMI], ≥30 kg/m(2)) were randomized to the treatment or placebo group. The treatment group received 6 capsules of a dietary supplement containing a proprietary blend of glucomannan, chitosan, fenugreek, G sylvestre, and vitamin C daily for 6 weeks, and the placebo group received 6 capsules of rice flour daily for 6 weeks. Body weight; percentage of body fat; absolute fat mass; lean body mass; BMI; upper abdominal, waist, and hip circumference; and anthropometric measurements were recorded at baseline and at study end. Patients completed daily dietary intake records on days 1 to 3 and days 40 to 42. They also completed weekly activity logs throughout the study. RESULTS Twenty-four subjects (mean [SD] age, 37.0 [8.2] years [range, 21-48years]; mean [SD] BMI, 35.7 [6.2] kg/m(2) [range, 28.9-50.9 kg/m(2)]) were assigned to the treatment group (8 women, 4 men) or the placebo group (9 women,3 men). Two subjects (8.3%; 1 patient [8.3%] from each group) dropped out for personal reasons unrelated to the study. No significant changes in the consumption of total calories; the percentage of calories ingested as carbohydrates, fat, or protein; or activity levels were found in either group throughout the study. Compared with the placebo group, the treatment group lost significantly more body weight (-2.3 kg vs 0.0 kg; P<0.01), percentage of body fat (-1.1% vs 0.2%; P<0.05), and absolute fat mass (-2.0 kg vs 0.2 kg; P<0.001). The treatment group also experienced a significantly greater reduction in upper abdominal circumference (-4.5 cm vs -0.7 cm), waist circumference (-4.1 cm vs 0.1 cm), and hip circumference (-2.9 cm vs 0.6 cm) compared with the placebo group (P<0.05 for all). No significant changes in heart rate or blood pressure were found in either group. Both the treatment and the placebo were well tolerated. CONCLUSION Within the context of this study, the novel combination of glucomannan, chitosan, fenugreek, G sylvestre, and vitamin C results in significant body weight and fat loss in obese adults.

Abstract
OBJECTIVE This study aimed to describe the changes in weight and waist circumference (WC), examine the incidence of obesity as defined by body mass index (BMI) and WC, and describe the changes in the prevalence of obesity over 12 years. METHODS In 1999/2000, 11,247 adults aged ≥25 years were recruited from 42 randomly selected areas across Australia. In total, 44.6% of eligible participants completed follow-up in 2011/12. Height, weight, and WC were measured at both surveys. RESULTS People who were 25-34 years of age at baseline gained an average of 6.7 kg weight and 6.6 cm WC, whereas those aged ≥75 years lost an average of 4.5 kg and gained an average of 0.8 cm. Women had a greater increase in WC than men, but did not differ in terms of weight gain. The 12-year incidence of obesity was 15.0% when defined by BMI and 31.8% when defined by WC. According to BMI and WC combined, the percentage of the cohort that was normal weight decreased from 33 to 21% and the percentage that was obese increased from 32 to 49% between baseline and 2012. CONCLUSIONS In addition to BMI, assessment of WC should be incorporated more frequently when assessing population trends of obesity and the burden of disease associated with excess adiposity.

Abstract
Background The purpose of this study is to describe the prevalence of overweight, general obesity, and abdominal obesity and examine their associations with socioeconomic status in a rural Chinese adult population. Methods This cross-sectional study was performed on 15,236 participants ≥ 35 years of age (6,313 men [41.4%] and 8,923 women [58.6%]). Each participant’s weight, height, waist circumference (WC), and hipline circumference (HC) were measured, and demographic and socioeconomic data were collected using questionnaires. Results The mean body mass index (BMI) values were 23.31 ± 2.96 and 23.89 ± 3.23 kg m-2 and the mean WC values were 79.13 ± 8.43 and 79.54 ± 8.27 cm for men and women, respectively. The age-standardized prevalence rates of overweight (BMI ≥ 24.0 kg m-2), general obesity (BMI ≥ 28.0 kg m-2), and abdominal obesity (WC ≥ 85 cm for men and ≥ 80 cm for women) were 32.0%, 6.7%, and 27.0% for men and 35.1%, 9.7%, and 48.3% for women, respectively. All gender differences were statistically significant (p < 0.001). In addition, the age-specific prevalence rates of general and abdominal obesity slowly decreased among men but sharply increased among women as age increased (p < 0.001). In subsequent logistic regression analysis, educational level was negatively associated with both general obesity and abdominal obesity among women but positively associated with abdominal obesity among men. No significant correlation was found between obesity and income. Conclusions These results suggest a high prevalence of obesity which might differ by gender and age, and an inverse association among women and a mixed association among men noted between education and obesity in our locality. Preventive and therapeutic programs are warranted to control this serious public health problem. The gender-specific characteristics of populations at high-risk of developing obesity should be taken into consideration when designing interventional programs.

Abstract
Background Central obesity is thought to be more pathogenic than overall obesity and studies have shown that the association between waist circumference (WC) and mortality was strongest in those with a normal body mass index (BMI). The objective of our study was to determine secular trends in the prevalence of central obesity (WC ≥ 90 cm for men and ≥ 80 cm for women) among Chinese adults with normal BMI from 1993 to 2009 and to examine the impact of performance of combined BMI and WC on the prevalence of obesity in Chinese adults. Methods We used data from the China Health and Nutrition Survey (CHNS) conducted from 1993 to 2009. From which we included a total of 52023 participants aged ≥ 18 years. Results The age-standardized prevalence of central obesity among Chinese adults with BMI < 25 kg/m2 increased from 11.9% in 1993 to 21.1% in 2009 (P for linear trend <0.001). The upward trends were noted in both genders, all ages, rural/urban settings, and education groups (all P for linear trend <0.001), with greater increments in men, participants aged 18–64 years, and rural residents (P for interaction terms survey × sex, survey × age, and survey × rural/urban settings were 0.042, 0.003, and < 0.001, respectively). Trends in the prevalence of central obesity were similar when a more stringent BMI < 23 kg/m2 cut point (Asian cut point) was applied. Central obesity is associated with a higher risk of incident hypertension within normal BMI category. More than 65% individuals with obesity would be missed if solely BMI was measured. Conclusions We observed an upward trend in the prevalence of central obesity among participants with normal BMI irrespective of sex, age, rural/urban settings, and education level. Central obesity is associated with a higher risk of incident hypertension within normal BMI category. Approximately two thirds of the individuals with obesity would be missed if WC was not measured. It is, therefore, urgent to emphasize the importance of WC as a measure to monitor the prevalence of obesity.

Abstract
AIMS Excessive weight is associated with increased sickness absence from work due to obesity-linked health problems. However, it is not known which obesity measure best predicts sickness absence. First, we aimed to compare body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) as predictors of sickness absence spells of various lengths. Second, we aimed to compare BMI based on self-reported and measured weight and height as a predictor of sickness absence to assess the validity of self-reported BMI. METHODS The participants were 5750 employees of the City of Helsinki, aged 40-60 years, who were followed up on average for 4.8 years using the employer's register. Sickness absence spells were classified as self-certified short (1-3 days), medically certified medium length (4-14 days), and long (>14 days) absence spells. RESULTS All measures of body weight predicted sickness absence. The relative rates of long sickness absence in the highest quintile as compared to the lowest quintile varied in women from 1.62 (95% CI 1.35-1.94) to 1.89 (95% CI 1.62-2.23) and in men from 1.40 (95% CI 0.76-2.59) to 2.33 (95% CI 1.32-4.11). Differences in the predictive power of BMI and WC were small: both were more strongly associated with sickness absence than WHR. Self-reported BMI performed equally well as measured BMI. CONCLUSIONS BMI - measured or self-reported - is a valid anthropometric indicator of body weight and predictor of obesity-associated health-risks. Its use is feasible for research purposes as well as for the assessment of weight-related risks to work ability.

Abstract
BACKGROUND The aim of this study was to investigate the association between obesity and prehypertension (preHT) after adjustment for socioeconomic position and health behavior factors. METHODS The study sample included 1973 Korean men and women, 45-64 years of age. Subjects were classified into three groups based on their baseline blood pressure: prehypertensive, hypertensive and normotensive. Men with a waist circumference ≥90 cm or women ≥80 cm were considered abdominally obese. Body mass index (BMI) obesity was defined as having a BMI ≥25. The prevalence of abdominal obesity and BMI obesity was calculated with age adjustment using a direct method. Multinomial logistic regression analysis was applied. RESULTS The prevalence of preHT in our study was 52.8%. We found that subjects with abdominal obesity were 2.06 times as likely to be prehypertensive as those without it and people with BMI obesity were 1.89 times as likely to be prehypertensive as those without it. Interestingly, men with BMI obesity had a higher preHT risk, while women with abdominal obesity had a higher preHT risk. CONCLUSIONS Statistical analyses of a community-based random sample of the Korean population indicate that obesity is associated with preHT in Korean middle-aged subjects.

Abstract
OBJECTIVE To determine possible acute kidney injury with new marker neutrophil gelatinase-associated lipocalin (NGAL) in urine and to show the relationship between changes of this marker and conventional markers in patients undergoing shock wave lithotripsy (SWL). METHODS In patients with kidney stones, serum urea, creatinine, urine microalbumin, and NGAL levels were determined before SWL and at the first, second, and seventh days after SWL. In addition, patients who had undergone SWL were evaluated with Technetium-99m (Tc99m)-dimercaptosuccinic acid (DMSA) and Tc99m-diethylenetriaminepenta acetate renal scintigraphy 1 week before and 3 months after SWL. RESULTS AND LIMITATIONS Forty patients were included in the study. All patients had a single stone in the kidney with an average size of 9.25 mm (range 5-15). No statistical change was found in the levels of average serum urea and creatinine levels, urine microglobulin, and NGAL levels, which were measured before SWL and after SWL. No significant difference was identified in urine NGAL and microalbumin levels of the groups, which were separated by shock wave number and shock energy amount on the first, second, and seventh days after SWL. In the high-energy SWL group, 3 patients had a statistical decrease in their differential kidney function measured with Tc99m difference between differential function rates of the kidney before and after SWL (DMSA) after 3 months after SWL. CONCLUSION Our study found that, using both new and conventional parameters in the acute stage and 3 months later, SWL treatment does not cause acute kidney damage.

Abstract
OBJECTIVE The objective of this study was to determine the prevalence of impaired glucose regulation in a young, asymptomatic Kuwaiti population. SUBJECTS AND METHODS A cross-sectional study of 484 Kuwaitis (females: 311, and males: 173, aged 17-24 years), students at a public college for basic education, was conducted. Each participant underwent a 75-gram oral glucose tolerance test, and biochemical testing for hemoglobin A(1c) (HbA(1c)), total cholesterol and triglyceride levels. Physical examinations were performed to measure body mass index (BMI), waist circumference and blood pressure. RESULTS The prevalence of impaired glucose regulation (impaired fasting glucose, impaired glucose tolerance, and elevated HbA(1c) levels) was 32%, including 4% with newly diagnosed diabetes. Of the 484 participants, 47 (10%) of the population had hypertension and 52 (11%) had dyslipidemia. A total of 244 (50%) were classified as overweight/obese (BMI >25 kg/m(2)) and 201 (42%) had an elevated waist circumference (≥88 cm in females; ≥102 cm in males). Impaired glucose regulation was significantly related to increased waist circumference (p = 0.021) but not to increased BMI (p = 0.181). Those with impaired glucose regulation also had a higher prevalence of hypertension (p = 0.05), particularly systolic hypertension (p = 0.023). CONCLUSION Kuwaiti youth have a high prevalence of impaired glucose regulation and overweight/obesity. Waist circumference, rather than BMI, may be a more appropriate screening tool to predict impaired glucose regulation in Kuwaiti youth.

Abstract
Though seemingly an easy procedure to perform, there is no universally accepted approach to the measurement of waist circumference (WC) in the clinical setting. Measurement of WC can be affected by a myriad of factors including patient movement or position changes, poor positioning of the measuring tape or differences in tension applied to the tape by the clinician. Changes in any one of these factors can reduce the validity and reliability of the measurement. This is of particular importance in clinical trials where changes in WC represent a therapeutic endpoint. Recognition of the need for a more standardized and reliable means to perform WC measurement led to the development of a novel, validated technique. The Height of Iliac Crest (HIC) method uses a standardized technique that increases the reliability of measurement by minimizing some of the weaknesses and variations of previous methods. The purpose of the following study was to validate the accuracy and reproducibly of the HIC method for obtaining WC measurement data. This study demonstrates that accurate and reproducible results can be obtained through the application of the HIC method for measuring waist circumference.

Abstract
Epidemiological evidence indicates that obesity plays an important role in cancer incidence. A telephone survey of 1,433 adults, aged 18+ years who reported their knowledge and beliefs regarding behavioral risk factors for cancer, was conducted. Most respondents believed that people can take steps to reduce cancer risk; however, many, particularly obese respondents, did not rate being overweight as a very important risk factor. A dedicated public education campaign focused on overweight and cancer is needed to address the significant gap in knowledge about the role of weight control in preventing cancer, particularly among those most afflicted.

Abstract
The obesity pandemic has grown to concerning proportions in recent years, not only in the Western World, but in developing countries as well. The corresponding decrease in male fertility and fecundity may be explained in parallel to obesity, and obesity should be considered as an etiology of male fertility. Studies show that obesity contributes to infertility by reducing semen quality, changing sperm proteomes, contributing to erectile dysfunction, and inducing other physical problems related to obesity. Mechanisms for explaining the effect of obesity on male infertility include abnormal reproductive hormone levels, an increased release of adipose-derived hormones and adipokines associated with obesity, and other physical problems including sleep apnea and increased scrotal temperatures. Recently, genetic factors and markers for an obesity-related infertility have been discovered and may explain the difference between fertile obese and infertile obese men. Treatments are available for not only infertility related to obesity, but also as a treatment for the other comorbidities arising from obesity. Natural weight loss, as well as bariatric surgery are options for obese patients and have shown promising results in restoring fertility and normal hormonal profiles. Therapeutic interventions including aromatase inhibitors, exogenous testosterone replacement therapy and maintenance and regulation of adipose-derived hormones, particularly leptin, may also be able to restore fertility in obese males. Because of the relative unawareness and lack of research in this area, controlled studies should be undertaken and more focus should be given to obesity as an etiolgy of male infertility.

Abstract
OBJECTIVE To estimate the incremental effect of waist circumference (WC) on health-care costs among overweight and obese subjects after adjusting for body mass index (BMI). METHODS A prospective study. The subjects were members of Internet panels in the United States (US) and Germany. 10,816 individuals (United States: n = 5410; Germany: n = 5406) aged 30-70 years with BMI scores between 20 and 35 kg/m(2) were recruited and grouped by category: healthy weight (BMI 20-24.9 kg/m(2)), overweight (BMI 25-29.9 kg/m(2)), and obese (BMI 30-35 kg/m(2)). Within the overweight and obese categories, the individuals were stratified by sex and within those subgroups, characterized as above or below the median WC. The subjects self-reported weight, WC, and health-care resource use at baseline, 3 months, and 6 months using online questionnaires. Over 65% of the recruited subjects completed all surveys. Resource utilization was translated into health-care costs by multiplying unit costs from national sources in each country. Annualized health costs were summarized for subjects with low and high WC within the overweight and obese categories. A two-part model generated predicted annual costs because of the WC difference controlling for BMI, demographic, and lifestyle variables among the overweight and obese subjects. RESULTS When BMI and other characteristics are constant, annual health-care costs are 16% to 18% higher in Germany and 20% to 30% higher in the United States for the subjects with a high WC compared with subjects with a low WC. CONCLUSIONS Targeting people with a high waist circumference for weight management whether they are overweight or obese may maximize cost-efficacy.

Abstract
INTRODUÇÃO: O índice de massa corporal (IMC) é amplamente utilizado por profissionais de saúde na avaliação do estado nutricional e do risco de mortalidade. No entanto, esse índice não fornece informações sobre a distribuição e a proporção da gordura corporal. OBJETIVO: Verificar a eficiência do IMC em identificar indivíduos com excesso de gordura corporal e com obesidade abdominal. MÉTODOS: A amostra constituiu-se de 98 homens com idade entre 20 e 58 anos. A avaliação antropométrica incluiu peso, altura, circunferência da cintura (CC) e do quadril. A composição corporal foi avaliada por bioimpedância elétrica tetrapolar. RESULTADOS: A amostra foi predominantemente jovem, 50% dos indivíduos com idade entre 20 e 29 anos. O sobrepeso (IMC > 25kg/m²) e a obesidade abdominal (CC > 94cm) foram constatados em 36,7% e 18,4% dos homens avaliados, respectivamente. A circunferência da cintura foi a medida antropométrica que mais se correlacionou com o IMC (r = 0,884; p < 0,01) e com o percentual de gordura corporal (r = 0,779; p < 0,01). A sensibilidade do IMC, para diagnosticar indivíduos com circunferência da cintura, relação cintura-quadril (RCQ) e percentual de gordura corporal elevados, foi de 94,4%, 100% e 86,6%, respectivamente; isso demonstra a sua adequação para estudos populacionais com o objetivo de identificar indivíduos com obesidade abdominal e/ou excesso de gordura corporal. Entretanto, na avaliação individual, o IMC não foi adequado para esse mesmo diagnóstico devido aos baixos valores preditivos positivos encontrados: 47,2% para CC, 11,1% para RCQ e 36,1% para percentual de gordura corporal. A idade > 30 anos foi fator de risco para sobrepeso, obesidade abdominal e excesso de gordura corporal. CONCLUSÕES: Ressalta-se a importância da combinação do IMC e circunferência da cintura na avaliação do estado nutricional de homens adultos, já que a obesidade abdominal foi constatada também naqueles indivíduos que não foram diagnosticados como obesos pelo IMC.

Abstract
OBJECTIVE To compare the effects of tibolone with those of continuous combined hormone replacement therapy (HT) on body composition in postmenopausal women. METHODS One hundred and fifty postmenopausal women were enrolled in a randomized, controlled trial to compare the effects of tibolone with continuous combined HT on body composition. Patients were randomly allocated into three groups and followed for 9 months. Of the subjects included, 50 women received 2.5 mg tibolone plus one Cal+D tablet (500 mg calcium and 200 IU vitamin D) daily, 50 women received 0.625 mg conjugated equine estrogen and 2.5 mg medroxyprogesterone acetate (CEE/MPA) plus one Cal+D tablet daily, and the rest (50 women) received only one Cal+D tablet and served as a control group. Body composition was evaluated with measurements of body mass index (BMI), weight, waist-to-hip ratio (WHR), fat mass and fat-free mass (FFM) before and after the intervention. Measurements of body fat mass percentage, fat mass, body fat-free mass percentage and fat-free mass (FFM) were assessed by measurement of skin-fold thickness. RESULTS Tibolone significantly increased weight, BMI and FFM and decreased WHR after the treatment in comparison with baseline (p < 0.05). However, only weight and BMI increased significantly in the CEE/MPA group after the treatment (p < 0.05). There were significant increases in weight, BMI and fat mass in the control group after 9 months. In the comparison of the parameters after the treatment between the three groups, tibolone significantly increased FFM compared with the control and CEE/MPA groups (p < 0.01). CONCLUSIONS The effect of tibolone on body composition is favorable and therefore tibolone may be regarded as an alternative to continuous combined hormone therapy in postmenopausal women.

Abstract
Metabolic syndrome (MetS) is a cluster of risk factors, including elevated mean arterial pressure (MAP), atherogenic dyslipidemia (elevated triglycerides [TRG]), abdominal obesity (increased body mass index [BMI]), glucose intolerance (elevated glucose [GLU]), and prothrombotic/inflammatory state (increases in uric acid [UA]), that are associated with increased risk of cerebrovascular disease. We studied if an association existed between MetS components and human immunodeficiency virus (HIV)-associated cryptogenic strokes-those not caused by HIV complications, endocarditis, or stimulant abuse. We performed a retrospective case-control study. Eleven cryptogenic strokes were identified from 2346 HIV-infected (HIV+) participants. Each case was matched by age, sex, and date of stroke diagnosis to five HIV+ controls without stroke. Nonparametric stratified Wilcoxon ranked sum tests with subsequent mixed effect logistic regression determined the influence of each MetS component on HIV-associated cryptogenic stroke. Although each MetS component appeared higher for HIV+ cases with cryptogenic strokes than HIV+ controls, only MAP (odds ratio [OR] = 5.70, 95% confidence interval [CI] = 1.15-28.3) and UA (OR = 1.88, 95% CI = 1.06-3.32) were statistically different. A significantly higher percentage of HIV-associated cryptogenic stroke cases met criteria for MetS (4/11 = 36%) compared to HIV+ controls (6/55 = 11%). This observational study suggests a possible role for MetS components in HIV+ cryptogenic stroke cases. Although MetS is defined as a constellation of disorders, elevated hypertension and hyperuricemia may be involved in stroke pathogenesis. Reducing MetS component levels in HIV+ patients could therefore protect them from subsequent stroke.

Abstract
AbstractObjectiveTo examine the association between television advertising exposure and adults’ consumption of fast foods.DesignCross-sectional telephone survey. Questions included measures of frequency of fast-food consumption at different meal times and average daily hours spent watching commercial television.Subjects/settingSubjects comprised 1495 adults (41 % response rate) aged ≥18 years from Victoria, Australia.ResultsTwenty-three per cent of respondents usually ate fast food for dinner at least once weekly, while 17 % consumed fast food for lunch on a weekly basis. The majority of respondents reported never eating fast food for breakfast (73 %) or snacks (65 %). Forty-one per cent of respondents estimated watching commercial television for ≤1 h/d (low viewers); 29 % watched for 2 h/d (moderate viewers); 30 % watched for ≥3 h/d (high viewers). After adjusting for demographic variables, high viewers were more likely to eat fast food for dinner at least once weekly compared with low viewers (OR = 1·45; 95 % CI 1·04, 2·03). Both moderate viewers (OR = 1·53; 95 % CI 1·01, 2·31) and high viewers (OR = 1·81; 95 % CI 1·20, 2·72) were more likely to eat fast food for snacks at least once weekly compared with low viewers. Commercial television viewing was not significantly related (P> 0·05) to fast-food consumption at breakfast or lunch.ConclusionsThe results of the present study provide evidence to suggest that cumulative exposure to television food advertising is linked to adults’ fast-food consumption. Additional research that systematically assesses adults’ behavioural responses to fast-food advertisements is needed to gain a greater understanding of the mechanisms driving this association.

Abstract
OBJECTIVE To evaluate the reliability of anthropometric measurements (weight, height, Body Mass Index (BMI), waist and hip circumferences (WC; HC) and waist-to-hip ratio (WHR)) performed by doctors to assess obesity. METHOD Repeated anthropometric measurements were performed by 12 primary care physicians on 24 adult volunteers in Geneva, Switzerland, 2006. Volunteers (54% women, mean age 41) had a mean BMI of 28.1 (respective mean values for WC, HC and WHR: 91.4, 108.3, 0.84). Inter-observer reliability coefficient (R) and percent disagreement in categorisation of volunteers (normal weight, overweight, obesity, abdominal obesity) were computed according to these measurements. RESULTS The inter-observer reliability for weight, height, and derived BMI were excellent (R>0.99), but unsatisfactory for WC (R=0.92), HC (R=0.76) and WHR (R=0.51). Based on the BMI, only 1% of the volunteers were misclassified as overweight or obese, whereas the use of WC and WHR lead to misclassification in 6% and 23% respectively. Reliability for the measurements improved after a one-hour training in anthropometric measurements (R=0.97 for WC, 0.92 for HC and 0.89 for WHR), but the proportion who were misclassified remained high despite the training session for WC (5%) and WHR (9%). CONCLUSIONS BMI remains the most reliable measure to detect obesity in medical practice, whereas WC, HC and WHR are less reliable. These results challenge current recommendations on obesity-related cardio-vascular risk management based on WC and WHR and underline the need for further research to improve the reliability of anthropometric measurements by doctors.

Abstract
BACKGROUND Obesity can be defined using body mass index (BMI) or waist (abdominal obesity). Little information exists regarding its prevalence and determinants in Switzerland. Hence, we assessed the levels of obesity as defined by BMI or waist circumference in a Swiss population-based sample. METHODS Cross-sectional, population-based non-stratified random sample of 3,249 women and 2,937 men aged 35-75 years living in Lausanne, Switzerland. Overall participation rate was 41%. RESULTS In men, the prevalences of overweight (BMI > or =25 kg/m2) and obesity (BMI > or =30 kg/m2) were 45.5% and 16.9%, respectively, higher than in women (28.3% and 14.3%, respectively). The prevalence of abdominal obesity (waist > or =102 in men and > or =88 cm in women) was higher in women than in men (30.6% vs. 23.9%). Obesity and abdominal obesity increased with age and decreased with higher educational level in both genders. In women, the prevalence of obesity was lower among former and current smokers, whereas in men the prevalence of obesity was higher in former smokers but did not differ between current and never smokers. Multivariate analysis showed age to be positively related, and education and physical activity to be negatively related with obesity and abdominal obesity in both genders, whereas differential effects of smoking were found between genders. CONCLUSION The prevalence of abdominal obesity is higher than BMI-derived obesity in the Swiss population. Women presented with more abdominal obesity than men. The association between smoking and obesity levels appears to differ between genders.

Abstract
Obesity is a rapidly increasing public health problem, with surveillance most often based on self-reported values of height and weight. We conducted a systematic review to determine what empirical evidence exists regarding the agreement between objective (measured) and subjective (reported) measures in assessing height, weight and body mass index (BMI). Five electronic databases were searched to identify observational and experimental studies on adult populations over the age of 18. Searching identified 64 citations that met the eligibility criteria and examined the relationship between self-reported and directly measured height or weight. Overall, the data show trends of under-reporting for weight and BMI and over-reporting for height, although the degree of the trend varies for men and women and the characteristics of the population being examined. Standard deviations were large indicating that there is a great deal of individual variability in reporting of results. Combining the results quantitatively was not possible because of the poor reporting of outcomes of interest. Accurate estimation of these variables is important as data from population studies such as those included in this review are often used to generate regional and national estimates of overweight and obesity and are in turn used by decision makers to allocate resources and set priorities in health.

Abstract
BACKGROUND Obesity is a growing health issue in Canada, and identifying the determinants of weight gain is important for the development of appropriate prevention strategies. PURPOSE To quantify the association between musculoskeletal fitness (MSF) and subsequent weight gain and development of obesity. METHODS The sample included 606 participants (20-69 yr; 291 men, 315 women) from the Physical Activity Longitudinal Study (PALS), a follow-up of participants from the 1981 Canadian Fitness Survey. Standardized assessments of height, weight, MSF (push-ups, sit-ups, grip strength, and trunk flexibility), and cardiorespiratory fitness were made at baseline (1981). Follow-up data on self-reported height and weight and body mass index (BMI) were collected by survey in 2002-2004. Logistic regression was used to predict obesity and weight gain of > or = 10 kg between 1981 and 2002-2004. RESULTS During the 20-yr follow-up, the prevalence of obesity (BMI > or = 30 kg.m(-2)) increased from 3.1 to 15.2%, reflecting a mean weight gain of 7.4 kg (men: 6.7 kg; women: 8.1 kg). Further, independent of age, sex, baseline BMI, physical activity, cardiorespiratory fitness, smoking, alcohol consumption, and income, low MSF was associated with significantly higher odds of having gained at least 10 kg during follow-up (OR: 1.78, 95% CI: 1.14-2.79). CONCLUSIONS The results indicate that MSF is a significant predictor of weight gain during a 20-yr period. Promoting participation in activities that enhance MSF may be beneficial in attenuating age-related weight gain and in preventing obesity among Canadians.

Abstract
The objective of the present study was to compare different methods for evaluating body fat percentage (BF%) (anthropometric methods and bioelectrical impedance analysis) in university students. Subjects were 653 healthy students whose mean age, body height, body weight and BMI were 21·1 (SD 2·5) years, 166·0 (SD 8·4) cm, 62·8 (SD 11·0) kg and 22·7 (SD 3·1) kg/m2, respectively. Results showed that BMI is a poor predictor of body fatness since the sensitivity was low in comparison with the reference method (Siri equation). The lowest values of BF% were obtained using the reference method (Siri equation) (21·8 (SD 6·8)%). The two methods with the highest agreement were Siri and Lean (mean difference, −0·5), followed by Brozek (mean difference, −1·4) and Deurenberg (mean difference, −1·5). The largest mean difference for BF% was between Siri and impedance (−4·5). Although the methods and/or equations used in the present study have been commonly utilised to estimate BF% in young adults, the results must be interpreted with caution in the diagnosis and monitoring of overweight and obesity.

Abstract
BACKGROUND Epidemiological studies find a progressive increase in the prevalence of elevated blood pressure with increasing adipose tissue. But there is no common opinion about which effectiveness of the anthropometric measurement tools indicating general or android obesity are most important to follow up in patients with elevated blood pressures. OBJECTIVES To identify which anthropometric measurements are most closely related to blood pressure elevation. METHODS A cross-sectional descriptive study of 1727 subjects [894 (50.6%) men and 833 (48.2%) women, aged 18-65 years old] was held in Edirne, Turkey. Each subject's weight, height, waist and hip circumference, triceps skin fold and blood pressures was measured; waist to hip ratio and body mass index were calculated. The relations between blood pressure and different anthropometric variables in both genders were investigated in linear regression models. RESULTS The mean systolic and diastolic blood pressures were 123.49 +/- 17.60 and 78.79 +/- 10.37 mmHg. According to body mass index 23.7% of the subjects were obese (.29.9 kg/m(2)). When waist circumference cut-off points were compared with waist to hip ratio the android obesity ratio was doubled (32.3% versus 16.6%). 119 subjects (6.8%) were not obese according to body mass index but nonetheless had waist circumference measurements above the cut-off points suggesting a high cardiovascular risk. In the linear regression models waist circumference was found to be an independent risk factor for blood pressure in men; however body mass was more important index and waist circumference somewhat less so for women. CONCLUSION In primary care waist circumference should be a useful tool screening for and following android obesity in patients with elevated blood pressure.

Abstract
BACKGROUND Overweight and obesity are increasing rapidly in the US and the Department of Defense (DoD). We examined whether weight trends evidenced in the general population and DoD are occurring among individuals entering US Air Force (USAF) Basic Military Training (BMT). METHODS Individuals entering the USAF in 1996 (AF1996; N = 29,036) and 2000 (AF2000; N = 31,080), ages 17-29 years were surveyed. The two recruit cohorts were compared to age-matched individuals from the 1996 (N = 22,153) and 2000 (N = 31,861) Behavioral Risk Factor Surveillance System Survey (BRFSS). RESULTS Crude rates for all age groups and age- and gender-standardized prevalence rates reflected significant increases in overweight/obesity among recruits. The direct standardized prevalence of overweight/obesity increased nearly 24%, from 14.8% in AF1996 to 18.3% in AF2000. The increase in overweight/obesity was particularly large among male recruits ages 25-29 (i.e., from 36.4% to 44.5%) between 1996 and 2000. CONCLUSIONS USAF cohorts were less likely to be overweight than corresponding BRFSS samples. There were 19.1 and 20.2 percentage point differences between overall crude rates of overweight/obesity between AF1996 and BRFSS 1996 and AF2000 and BRFSS 2000, respectively. Nevertheless, overall rates of overweight and obesity are increasing among young recruits in the USAF at a fairly marked rate (approximately one percentage point per year).
