ABSTRACT=<p><bold>Objectives:</bold> Obesity is a risk factor for several chronic conditions, including sleep disorders. We aimed to analyze the relationship between BMI, body fat percentage (FAT%), hip and waist circumference, and weight on the duration of nocturnal sleep.</p><p><bold>Methods:</bold> This study was part of the MASHAD cohort study. In all participants BMI and FAT% were measured. BMI was used to categorize individuals as obese, overweight, and normal subjects. FAT% was used to categorize individuals into tertile: tertile 1 (low) &lt; 27.5, tertile 2 (medium) 27.5–41, and tertile 3 (high) &gt; 41. The level of nightly sleep duration was categorized into three groups: &lt;6, 6–8 (reference group), and &gt;8 h.</p><p><bold>Results:</bold> There was a significant inverse association between body weight and duration of sleep (<italic>p</italic> &lt; 0.05). Obese and overweight participants had 1.152 OR (CI:1.083–1.225) and 1.126 OR (CI:1.063–1.194) for a short duration of nocturnal sleep, respectively, relative to those with a normal BMI.</p><p><bold>Conclusion:</bold> BMI was an independent determinant of nocturnal sleep duration; obesity and overweight may have negative consequences on sleep duration. Weight control should be considered as a factor in adjusting sleep quality.</p>
