“…Short sleep durations have been associated with increased prevalence of obesity in Spain, Japan and the U.S. [54][55][56][57]. A French study of adults dichotomized sleep duration and found a slightly but significantly higher mean BMI among women reporting sleeping 6 hours less versus those sleeping more than six hours (24.4 vs. 23.4 kg/m 2 ) after adjustment for age and area of residence, but this difference was not observed among men [58]. Several studies have observed a U-shaped association between sleep duration and body mass index (BMI) [41,59,60], which indicates that both short and long sleep is associated with higher BMI.…”

SynopsisOver the past 30 years there has been an increase in the prevalence of obesity and diabetes, both of which can have serious consequences for longevity and quality of life. Sleep durations may have also decreased over this time period. This chapter reviews laboratory and epidemiologic evidence for an association between sleep loss and impairments in glucose metabolism and appetite regulation, which could increase the risk of diabetes or weight gain. Keywordssleep; appetite; diabetes; obesity; ghrelin; leptin IntroductionDiabetes and obesity are two debilitating chronic diseases that are increasing at an alarming rate worldwide [1,2]. Voluntary sleep restriction may play a role in the rapid increase in the prevalence of diabetes and obesity, and this chapter will review the evidence for such a link. Sleep restriction or impaired sleep may be more common in modern society than in past decades [3,4]. A survey study from 1960 found modal sleep duration to be 8.0 to 8.9 hours [5], while another survey study in 1995 observed a modal category of only 7 hours [6]. Recent national data also indicate that a greater percentage of adult Americans report sleeping 6 hours or less in 2004 than in 1985 [7]. Thus, the increase in the prevalence of obesity and diabetes appears to be mirrored by a decrease in average sleep duration in the U.S.In simplistic terms, weight gain occurs when there is positive energy balance, that is, energy intake is greater than energy expenditure (see Figure 1). Sleep restriction could affect endogenous processes related to energy balance, such as impairments in glucose metabolism and an upregulation of appetite. Sleep restriction could also affect exogenous factors such as food choice and increased time available to eat. Sleep loss could also lead to reductions in physical activity or energy expenditure, but evidence in support of this hypothesis is lacking. Both impaired glucose metabolism and excess weight can increase the risk of developing type 2 diabetes. Thus, this chapter will first review laboratory studies that examine the effects of sleep loss on glucose metabolism and appetite regulation. The chapter will then review the epidemiological evidence for an association between sleep restriction and diabetes risk, increased body mass index and risk of obesity.Corresponding Author: Kristen L Knutson, Department of Health Studies, University of Chicago, 5841 S.

“…The results obtained by other authors are inconclusive. Most papers showed that associations between sleep duration and BMI are stronger, or occur only in women, not in men [16,17,42,45,46]. St-Onge et al [15] also state that the relationship be- tween self-reported sleep duration and body composition may be stronger in women than in men.…”

“…However, there have been few papers published in which the association between body composition and sleep duration was analysed, and their results are inconclusive [7,15]. Likewise, the influence of gender on the association between sleep duration and the risk of obesity has not been fully explained [7,[16][17][18].…”

Introduction: So far, the association between a longer sleep duration, state of health, and the risk of obesity and the influence of gender on the association between sleep duration and the risk of obesity has not been fully explained. Aim of the research: To examine the relationships between self-reported sleep duration, body mass index (BMI), and body fat percentage (%BF), and also to determine whether such associations are the same in men and in women. Material and methods: This study included 10,367 participants aged 37 to 66 years. Logistic regression was applied for risk assessment of the prevalence of abnormal BMI values and %BF in groups of sleep duration. Sleep of 7-8 h per night was adopted as a reference level. Results: In men, the risk of obesity was significantly greater only in the group sleeping ≤ 6 h (OR = 1.18, 95% CI: 1.08-1.28; p < 0.05); however, in women, only among those sleeping ≥ 9 h (OR = 1.14, 95% CI: 1.02-1.26; p < 0.05). The risk of obesity, determined on the basis of %BF, was higher only in individuals sleeping ≥ 9 h. In the adjusted model, it turned out to be significant in the general study population (OR = 1.28, 95% CI: 1.07-1.53; p < 0.05) and in women (OR = 1.14, 95% CI: 1.03-1.27; p < 0.05). Conclusions: In women, a greater risk of obesity was related to a longer sleep duration (≥ 9 h), whereas in men, the tendency of obesity occurrence along with shorter sleep (≤ 6 h). Thus, the physiological consequences of sleep duration may be different in women than in men.

RESUMO A formação do profissional médico impõe modificações nocivas ao estilo de vida, predispondo ao ganho de peso. O objetivo deste estudo foi realizar uma revisão acerca das prevalências de sobrepeso e obesidade e possíveis fatores causais destas taxas em estudantes de Medicina (EM) e médicos residentes (MR). Realizou-se uma busca nas bases de dados on-line-Nutritional Status.-Food Habits.-Sedentary Lifestyle.-Sleep Deprivation.-Medical Education. ABSTRACT The training of the medical profession imposes harmful changes to lifestyle, which predisposes to weight gain. The aim of this study was to review the prevalence of overweight and obesity and possible causative factors in these rates in medical students (MS) and residents physicians (RP). We conducted a search of the databases online: PubMed / Medline (U.S. National Library of Medicine), Scieloand Lilacs with the keywords: "medical students" and "residents" associated with each of the terms: "body mass index (BMI)", "obesity", "overweight", "food intake", "sendentarism" and "sleep", and using

Environmental factors associated with body mass index in a population of Southern France

Abstract: Our results reveal the complexity that exists between BMI and environmental factors and stress the need to analyse and to handle these factors simultaneously.
