In recent decades, obesity has become a global epidemic
Lifestyles aimed at reducing energy intake and increasing calorie consumption can slow the progression of obesity, such as controlling diet and exercising
However, a significant percentage of adults now sleep less than 7 hours, and lack of sleep can lead to metabolic disorders
Recently, Zhang Yi, Xu Yawei, Xu Bei and others of the Tenth People's Hospital of Tongji University published a research paper
The study showed that short sleep duration (< 7 hours/day) was independently associated with an increase in fat mass in parts of the body (arms, legs), especially in men and obese people<b10>.
Many previous studies have shown that sleep deprivation is associated with an increased risk of obesity in adults, but most of these studies use body mass index (BMI) to measure obesity, with limited ability to distinguish between fat mass and no fat mass, so it is impossible to accurately assess the relationship between
In addition, the distribution of adipose tissue in different parts of the human body is different, and the relationship between fat in different parts of adults and sleep duration has rarely been reported
Between 2011 and 2018, 9,413 participants were included in the National Health and Nutrition Examination Survey (NHANES
Dual-energy X-ray bone density meters were used to measure fat mass (FM) in different parts of them, including torso FM, arm FM, and leg FM
After adjusting for sociodemographic, lifestyle, comorbidities and drug use, people with short sleep (<7 hours/day) had higher trunk FMI, arm FMI, and leg FMI, compared with normal sleep (7-9 hours/day), while those who slept long (> 9 hours/day) had no significant difference from
In addition, those who were obese short-sleepers had higher arm and leg FMI compared to normal sleepers, while no correlation
Based on the above results, the research team concluded that short sleep duration (< 7 hours/day) was independently associated with increased fat in different parts of the body in American adults, especially men and obese people
Special note: This article only explores the correlation between sleep duration and fat in different parts of the body, and does not conclude that sleep deprivation leads to thicker arms and legs
