241. Association between regional body fat and cardiovascular disease risk among postmenopausal women with normal body mass index. Full Text available with Trip Pro

Association between regional body fat and cardiovascular disease risk among postmenopausal women with normal body mass index. Central adiposity is associated with increased cardiovascular disease (CVD) risk, even among people with normal body mass index (BMI). We tested the hypothesis that regional body fat deposits (trunk or leg fat) are associated with altered risk of CVD among postmenopausal women with normal BMI.We included 2683 postmenopausal women with normal BMI (18.5 to <25 kg/m2) who (...) participated in the Women's Health Initiative and had no known CVD at baseline. Body composition was determined by dual energy X-ray absorptiometry. Incident CVD events including coronary heart disease and stroke were ascertained through February 2017. During a median 17.9 years of follow-up, 291 incident CVD cases occurred. After adjustment for demographic, lifestyle, and clinical risk factors, neither whole-body fat mass nor fat percentage was associated with CVD risk. Higher percent trunk fat

242. Body mass index and body composition in relation to 14 cardiovascular conditions in UK Biobank: a Mendelian randomization study. Full Text available with Trip Pro

Body mass index and body composition in relation to 14 cardiovascular conditions in UK Biobank: a Mendelian randomization study. The causal role of adiposity for several cardiovascular diseases (CVDs) is unclear. Our primary aim was to apply the Mendelian randomization design to investigate the associations of body mass index (BMI) with 13 CVDs and arterial hypertension. We also assessed the roles of fat mass and fat-free mass on the same outcomes.Single-nucleotide polymorphisms associated (...) , atrial fibrillation, and pulmonary embolism. The odds ratio (OR) per 1 kg/m2 increase in BMI ranged from 1.06 [95% confidence interval (CI) 1.02-1.11; P = 2.6 × 10-3] for pulmonary embolism to 1.13 (95% CI 1.05-1.21; P = 1.2 × 10-3) for aortic valve stenosis. There was suggestive evidence of positive associations of genetically predicted fat mass index with nine outcomes (P < 0.05). The strongest magnitude of association was with aortic valve stenosis (OR per 1 kg/m2 increase in fat mass index 1.46

243. Body fat indicators perform better than body mass index in identifying abnormal lipid profiles in boys but not in girls. (Abstract)

Body fat indicators perform better than body mass index in identifying abnormal lipid profiles in boys but not in girls. BMI as a body weight indicator, may inadequately represent the biological effect of body fat on lipid profiles. This study aims to assess whether body fat indicators were superior to BMI for recognizing children with dyslipidemia.A nationwide cross-sectional study involving 8944 pediatric participants aged 6-18 years. Measures of fat mass index (FMI), fat mass percentage (FMP (...) % higher than those of BMI-based overweight, respectively, all P < 0.01. Among girls, the associations of BMI with lipid profiles were substantially similar to FMI. All these results were almost identical when FMP was used instead of FMI.DXA measured body fat performs better than BMI in identifying abnormal lipid profiles in boys but not in girls.

244. Effect of Body Mass Index Category on Body Surface Area Calculation in Children Undergoing Cardiac Procedures. (Abstract)

Effect of Body Mass Index Category on Body Surface Area Calculation in Children Undergoing Cardiac Procedures. Many of the common equations used for body surface area determination were either introduced before the widespread prevalence of childhood obesity, contained very few children in their sample, or have not been assessed in overweight/obese children. Therefore, we compared 6 body surface area formulae to determine their performance across body mass index categories using cross-sectional (...) correlation coefficient (measure of precision), the Lin concordance correlation coefficient (measure of bias and precision), and the Bland-Altman limit-of-agreement. All comparisons were made across age, sex, and body mass index categories.Among the 1000 (mostly Caucasian: 76.1%) subjects, 16.7% were overweight, while 14.1% were obese and 51.2% were girls. All calculated body surface area data showed a strong positive correlation with each other and the derived reference body surface area values (0.99

245. Long-term effects of participation in a prenatal exercise intervention on body weight, body mass index, and physical activity level: a 6-year follow-up study of a randomized controlled trial. Full Text available with Trip Pro

Long-term effects of participation in a prenatal exercise intervention on body weight, body mass index, and physical activity level: a 6-year follow-up study of a randomized controlled trial. Background: Growing evidence supports that physical activity and exercise during pregnancy is favorable for the mother, with persisting benefits in the postpartum period. However, there is scant knowledge of the effect of a prenatal exercise program on long-term health and lifestyle habits. Objectives (...) : This 6-year follow-up study of a randomized controlled trial had two aims: (1) compare body weight, weight retention and body mass index (BMI) in the intervention group and control group, and (2) evaluate effects on physical activity level and recreational exercise. Materials and methods: Out of 105 participants initially randomized to either an intervention group, n = 52 (twice weekly group-exercises and physical activity counselling) or control group, n = 53 (standard prenatal care), 80 women (76.2

246. Operating on the Edge? Body Contouring Procedures in Patients with Body Mass Index Greater 35. (Abstract)

Operating on the Edge? Body Contouring Procedures in Patients with Body Mass Index Greater 35. Body contouring surgery after massive weight loss was shown to ameliorate the patient's quality of life and to enhance physical and psychological well-being. However, numerous patients are still obese when presenting for body contouring surgery, not able to lose additional weight for various reasons. Data regarding general feasibility, outcome, and postoperative complications in obese patients is rare (...) . The aim of this study was to investigate the outcome in body contouring procedures in obese patients.A retrospective chart review of 65 cases in 42 patients was performed. Patients with a body mass index (BMI) > 35 kg/m2 at the time of operation were enrolled and all different types of body contouring surgery were included. Complications were classified as major (need for surgical intervention) and minor complications.The median BMI of all patients was 38 kg/m2 (range 35.1-65.1 kg/m2). The majority

249. Advanced body composition assessment: from body mass index to body composition profiling Full Text available with Trip Pro

Advanced body composition assessment: from body mass index to body composition profiling This paper gives a brief overview of common non-invasive techniques for body composition analysis and a more in-depth review of a body composition assessment method based on fat-referenced quantitative MRI. Earlier published studies of this method are summarized, and a previously unpublished validation study, based on 4753 subjects from the UK Biobank imaging cohort, comparing the quantitative MRI method (...) with dual-energy X-ray absorptiometry (DXA) is presented. For whole-body measurements of adipose tissue (AT) or fat and lean tissue (LT), DXA and quantitative MRIs show excellent agreement with linear correlation of 0.99 and 0.97, and coefficient of variation (CV) of 4.5 and 4.6 per cent for fat (computed from AT) and LT, respectively, but the agreement was found significantly lower for visceral adipose tissue, with a CV of >20 per cent. The additional ability of MRI to also measure muscle volumes

250. Correlation between body mass index and obstructive sleep apnea severity indexes - A retrospective study. (Abstract)

Correlation between body mass index and obstructive sleep apnea severity indexes - A retrospective study. To evaluate if Body Mass Index (BMI) is correlated to Apnea-Hypopnea Index (AHI), mean arterial oxygen saturation (SaO2) and Nadir SaO2, which are all indexes defining the severity of the respiratory stress associated with Obstructive Sleep Apnea (OSA).Seventy-five adult patients (mean age 51.4) referred for polysomnography were retrospectively recruited. BMI was calculated for each patient (...) , as well as AHI, SaO2, and Nadir SaO2 recorded during polysomnography. Spearman's Rho test was used to evaluate if OSA severity was correlated to BMI values. First type error was set as p < 0.025.No correlation was observed between BMI and AHI, and between BMI and SaO2. A statistically significant negative correlation (r2 = 0.424; p < 0.001) was found between the BMI index and the Nadir SaO2.Higher BMI values were correlated with lower Nadir SaO2 during overnight polysomnography.

251. Body mass index and wealth index: positively correlated indicators of health and wealth inequalities in Nairobi slums Full Text available with Trip Pro

Body mass index and wealth index: positively correlated indicators of health and wealth inequalities in Nairobi slums Wealth index is a known predictor of body mass index (BMI). Many studies have reported a positive association between BMI and socioeconomic status (SES). However, an in-depth investigation of the relationship between BMI and wealth index is lacking for urban slum settings.To examine the association between BMI and wealth index in an urban slum setting in Nairobi, Kenya.A total (...) of 2003 adults between 40 and 60 years of age were included. BMI was derived from direct weight and height measurements. Wealth Index was computed using the standard principal component analysis of household amenities ownership. The relationship between BMI and wealth index was assessed using both linear and logistic regression models.We found that BMI linearly increased across the five quintiles of wealth index in both men and women, after adjusting for potential confounding factors.

256. High body mass index is a risk factor for difficult deep sedation in percutaneous mitral valve repair. Full Text available with Trip Pro

High body mass index is a risk factor for difficult deep sedation in percutaneous mitral valve repair. The safety and efficacy of deep sedation (DS) in MitraClip® procedures have been shown previously. However, clinical experience demonstrates that in some patients DS is difficult to achieve. We hypothesize that some patient characteristics can predict difficult DS.We prospectively analysed 69 patients undergoing MitraClip® procedures using DS. Application of DS was graded as simple (group 1 (...) characterized by a higher body mass index (33.7 ± 6.0 kg/m2 vs. 26.1 ± 4.1; p = 0.001), younger age (67 ± 13 years vs. 75 ± 13 years; p = 0.044), and reduced left ventricular ejection fraction (36% ± 10 vs. 45% ± 14; p = 0.051) and presented more often with an obstructive sleep apnoea syndrome (6.9% vs. 45.5%; p = 0.003). In the multivariate analysis, body mass index was an independent predictor of difficult DS. Using a body mass index of 31 kg/m2 as a cut-off value, the sensitivity of predicting difficult

Effectiveness of automatic tube potential selection with tube current modulation in coronary CT angiography for obese patients: Comparison with a body mass index-based protocol using the propensity score matching method. Reduced image quality from increased X-ray scatter and image noise can be problematic when coronary computed tomography angiography (CCTA) imaging is performed in obese patients. The aim of this study was to compare the image quality and radiation dose obtained using automatic (...) tube potential selection with tube current modulation (APSCM) with those obtained using a body mass index (BMI)-based protocol for CCTA in obese patients.A total of 203 consecutive obese (BMI > 30 kg/m2) patients were retrospectively enrolled, of whom 96 underwent CCTA with APSCM and 107 underwent a BMI-based protocol. After applying the propensity score matching method, the clinical parameters, subjective and objective image quality, and radiation dose were compared between the APSCM group

Neighbourhood disadvantage, geographic remoteness and body mass index among immigrants to Australia: A national cohort study 2006-2014. Obesity is socioeconomically, geographically and ethnically patterned. Understanding these elements of disadvantage is vital in understanding population obesity trends and the development of effective and equitable interventions. This study examined the relationship between neighbourhood socioeconomic disadvantage and geographic remoteness with prospective (...) trends in mean body mass index (BMI) among immigrants to Australia. Longitudinal data (2006-2014) from a national panel survey of Australian adults was divided into an immigrant-only sample (n = 4,293, 52.6% women and 19,404 person-year observations). The data were analysed using multi-level random effects linear regression modelling that controlled for individual socioeconomic and demographic factors. Male immigrants living in the most disadvantaged neighbourhoods had significantly higher mean BMI

Relation of body mass index to risk of developing inflammatory bowel disease amongst women in the Danish National Birth Cohort. Crohn's disease (CD) has traditionally been associated with weight loss and low BMI, yet paradoxically obesity has recently been suggested as a risk factor for CD, but not for ulcerative colitis (UC). We therefore hypothesized that the relation between BMI and CD is U shaped.To conduct a large population-based prospective cohort study of BMI and later risk of IBD
