Association between duration of the sleep and body weight

Abstract

Some studies have suggested that there could be an association between the duration of sleep in humans and development of the obesity. We have analyzed the group of the probands (n = 3970, 2038 males and 1932 females, aged 18-65 years), with permanent address in the Central or South Bohemia. We ascertained the relationship between the duration of their sleep (obtained per questionnaire) and body mass index, weight, height, the value of systolic and diastolic blood pressure, heart rate, waist and hip circumference, the values of total-, high density- and low density- cholesterol, thyroid hormone and body exercise performed. The optimal values of the body mass index (and optimal body weight) were associated with the duration of sleep 7 hours per night (P < 0.001). This association was found both in males and females and in both districts. Other anthropometrical and biochemical parameters were not associated with the sleep duration.

Sleep Duration and Waist Circumference in Adults: A Meta-Analysis

“…6,[17][18][19][20][21][22][23][24][25][26][27] Other researchers explore the overall relation of sleep to WC by conducting analyses that treat both sleep and WC as continuous variables. [28][29][30][31][32][33][34][35][36] In this meta-analytic review, studies that used an insufficient versus "normal" sleep comparison were coded in terms of how these groups were created to permit examination of whether differences in sleep duration categories contributed to significant heterogeneity among effect sizes.…”

“…The majority of research studies examining WC as a measure of central adiposity use tape measure assessments because of their ease and proven clinical utility. 37 Multiple approaches exist regarding the site on the body at which WC is measured, with measurements taken at the narrowest portion of the waist (the "minimal" waist 17,19,29,31 ), the umbilicus, 6,27,30 and, most commonly, at the midpoint between the iliac crest and the lowest rib margin, 18,[20][21][22][23]25,26,28,34,35 as recommended by the World Health Organization. 15 Measurement site was coded to investigate whether the effect sizes varied in terms of WC measurement site.…”

“…6,18,20,21 For studies lacking needed information to yield an effect size based on an insufficient sleep to normal sleep comparison (k = 9), an effect size based on the overall relation of sleep duration to WC was calculated. [28][29][30][31][32][33][34][35][36] Potentially moderating variables were tested using multiple meta-regression models. 39 These metaregression models are capable of examining multiple moderating variables simultaneously, even if they are correlated.…”

Association between Sleep Quality and Body Weight Status in Adults during the COVID-19 Pandemic

“…Of particular interest is that women with a score of more than zero in subjective sleep quality were substantially less capable of losing weight. Notably, women who registered an "excellent" quality sleep score showed a reasonable probability of sustaining weight loss effectively at 12 and 18 months of loss (24,25). Thus, PSQI global scores of more than five were related to a lower probability of successful weight loss in the long term.…”
