Distinct Relevance of Nightly Sleep Duration to Metabolic, Anthropometric, and Lifestyle Factors in Patients with Type 2 Diabetes

Abstract

Objective Although a number of studies have shown that both short and long sleep durations were associated with the risk of metabolic disorders related to obesity, the underlying mechanism is still not fully understood. In this study, we analyzed the association of sleep duration with metabolic, anthropometric, and lifestyle factors in patients with type 2 diabetes. Patients and Methods The subjects were 279 patients with type 2 diabetes 63 (52-70) years old (median and interquartile range) with a body mass index of 25.0 (22.2-28.3) kg/m 2 and HbA1c levels of 8.7% (7.6%-10.3%). Patients with advanced complications were excluded from the study. Diets were evaluated by registered dietitians using a software program. Body composition was assessed by the multifrequency bioelectrical impedance method. Results The mean self-reported nightly sleep duration was 6.4 h with no marked gender difference. Sleep duration was inversely correlated with the HbA1c levels, total energy intake, and intakes of carbohydrate, protein, and fat. The body fat ratio and skeletal muscle mass were correlated positively and negatively, respectively, with sleep duration. When the subjects were divided into three groups based on sleep duration, the intakes of total energy, carbohydrates, and fat tended to be high in those with <5.5 h of sleep, and the percentage of patients who had habitual physical activities was lower in those with >7 h of sleep. Conclusions The observation that sleep duration is distinctly associated with excessive eating and a sedentary lifestyle may provide a basis for effective lifestyle management of patients with type 2 diabetes.

Predictive Models of Muscle Strength in Older People with Type 2 Diabetes Mellitus

“…The volunteers who reported altered sleep had lower AMS. Sleep disorders are related to a lower level of physical activity, 66,67 thus corroborating the present study, which observed lower AMS in the irregularly active/sedentary elderly. Noteworthy, insufficient physical activity is a known factor for lower MS. 68 In this context, physical inactivity in diabetic elderly may be associated with sleep disorders and physical, emotional, and cognitive changes, especially physical and cognitive disability, as well as depressive symptoms.…”

Duração do sono, ingestão de energia e macronutrientes em indivíduos com síndrome metabólica

“…Contudo, em nossa investigação não foi encontrada associação estatisticamente significativa entre a duração do sono e o consumo energético diário total, o que também foi visto por Nakayama et al (2021) e Castro et al (2019). Todavia, um menor valor médio de quilocalorias totais foi observado no grupo de longa duração do sono, corroborando a hipótese de que a longa duração do sono leva a um menor consumo de energia nas refeições principais -desjejum, almoço e jantar (KANT; GRAUBARD, 2014;KIM;DEROO;SANDLER, 2011).…”
