Background & Aims: Gluteofemoral obesity (determined by measurement of subcutaneous fat in the hip and thigh regions) could reduce risks of cardiovascular and diabetic disorders associated with abdominal obesity. We evaluated whether gluteofemoral obesity also reduces the risk of Barrett's esophagus (BE), a premalignant lesion associated with abdominal obesity.
Methods: We collected data from non-Hispanic white participants in 8 studies in the Barrett's and Esophageal Adenocarcinoma Consortium. We compared measures of hip circumference (as a proxy for gluteofemoral obesity) from cases of BE (n = 1559) separately with 2 control groups: 2557 population-based controls and 2064 individuals with gastroesophageal reflux disease (GERD controls). Study-specific odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated using individual participant data and multivariable logistic regression and combined using a random-effects meta-analysis.
Results: We found an inverse relationship between hip circumference and BE (OR per 5-cm increase, 0.88; 95% CI, 0.81-0.96), compared with population-based controls in a multivariable model that included waist circumference. This association was not observed in models that did not include waist circumference. Similar results were observed in analyses stratified by frequency of GERD symptoms. The inverse association with hip circumference was statistically significant only among men (vs population-based controls: OR, 0.85; 95% CI, 0.76-0.96 for men; OR, 0.93; 95% CI, 0.74-1.16 for women). For men, within each category of waist circumference, a larger hip circumference was associated with a decreased risk of BE. Increasing waist circumference was associated with an increased risk of BE in the mutually adjusted population-based and GERD control models.
Conclusions: Although abdominal obesity is associated with an increased risk of BE, there is an inverse association between gluteofemoral obesity and BE, particularly among men.

Fat distribution patterns are increasingly linked to obesity-related cancers; however, their shared genetic determinants remain unclear. To identify shared genetic architecture between adiposity measures and obesity-related cancers. Utilizing large-scale summary statistics from genome-wide association study, we conducted genome-wide cross trait analyses of nine adiposity measures [body mass index (BMI), waist-to-hip (WTH) ratio, waist-to-hip ratio adjusted for BMI, arm fat ratio, trunk fat ratio, leg fat ratio, abdominal subcutaneous adipose tissue, gluteofemoral adipose tissue, and visceral adipose tissue] in five obesity-related cancers (colorectal cancer, esophageal adenocarcinoma, breast cancer, endometrial cancer, and ovarian cancer) to characterize their shared genetic architecture, biological pathways, and causal relationships.

Background: Growing evidence has indicated an association between obesity, measured by body mass index (BMI), and urate levels, as well as the risk of gout. However, BMI inadequately reflects the body's fat distribution, including variations in gluteofemoral, abdominal subcutaneous, and visceral adipose tissue (GFAT, ASAT, and VAT). This study aimed to utilize Mendelian randomization (MR) to investigate the causal associations between genetically predicted fat distribution, urate levels, and the risk of gout.

Objective: Our objective was to investigate causal associations of adiposity in different locations and metabolically favorable and unfavorable adiposity (MetFA and MetUFA, respectively) with grip strength.
Methods: Observational cross-sectional and Mendelian randomization (MR) (sex combined and stratified) analysis within UK Biobank (N ≤ 340,258) was used to assess the relationships of visceral, abdominal subcutaneous, and gluteofemoral adipose tissue, anterior and posterior thigh muscle fat infiltration (ATMFI and PTMFI, respectively), body fat (BF) percentage, MetFA, and MetUFA with grip strength.
Results: In inverse variance weighted MR analysis, SD increases in BF, MetFA, and ATMFI were associated with lower grip strength by the following: -0.

Previous studies have indicated that there is an association between obesity and bladder cancer (BCa). However, the relationship between fat distribution, which is more representative of the risk of obesity, and BCa remains unclear. This study aimed to investigate the causal relationship between fat distribution and BCa, and the mediating role of circulating metabolites.
