Abstract

Body mass and body fat composition are of clinical interest due to their links to cardiovascular- and metabolic diseases. Fat stored in the trunk has been suggested to be more pathogenic compared to fat stored in other compartments. In this study, we perform genome-wide association studies (GWAS) for the proportion of body fat distributed to the arms, legs and trunk estimated from segmental bio-electrical impedance analysis (sBIA) for 362,499 individuals from the UK Biobank. 98 independent associations with body fat distribution are identified, 29 that have not previously been associated with anthropometric traits. A high degree of sex-heterogeneity is observed and the effects of 37 associated variants are stronger in females compared to males. Our findings also implicate that body fat distribution in females involves mesenchyme derived tissues and cell types, female endocrine tissues as well as extracellular matrix maintenance and remodeling.

  • The genetic factors that help determine fat distribution are largely distinct from those that affect overall adiposity as estimated by BMI.

    “Importantly, the genetic factors that help determine fat distribution are largely distinct from those that affect overall adiposity as estimated by BMI.78,94”

    From Definition and diagnostic criteria of clinical obesity (2025) · cites this paper as [94]

    The Results (‘Overlap with findings from previous GWAS’; page unavailable) identify 29 body-fat-distribution signals not previously associated with an anthropometric trait, supporting some genetic distinction. But the same section reports that the strongest arm-fat-ratio associations occur at known BMI and adiposity loci, while ‘Correlation between fat ratios and anthropometric traits’ reports a strong genetic correlation between arm fat ratio and BMI in females. The blanket description ‘largely distinct’ omits this substantial overlap and variation by fat compartment and sex. (LLM, conf=0.87)

  • Genome-wide association studies have identified several hundred common variants that influence food intake, basal metabolic rate, and the energy used during a fixed amount of exercise.

    From Definition and diagnostic criteria of clinical obesity (2025) · cites this paper as [94]

    The Introduction (page unavailable) says GWAS have identified hundreds of loci associated with body mass and body fat distribution, not variants influencing food intake, basal metabolic rate, or energy used during a fixed amount of exercise. Searches for those three outcomes found no passage in our copy addressing the attributed claim. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
