Sleep duration and visceral adipose tissue: linear and nonlinear Mendelian randomization analyses

Increasing evidence suggests that sleep is important for fat metabolism. However, the causal relationship between sleep duration and visceral adipose tissue (VAT) needs to be further clarified. This study investigated the linear and nonlinear causal association between sleep duration and VAT.越来越多的研究证据表明，睡眠对脂肪代谢具有重要作用。然而，睡眠时长与内脏脂肪组织（visceral adipose tissue, VAT）之间的因果关联仍有待进一步阐明。本研究探究了睡眠时长与内脏脂肪组织之间的线性及非线性因果关联。
