“…Inconsistent associations were found between sleep duration and prevalence of diabetes in elderly Chinese. Several cross-sectional and prospective studies suggest a U-shaped association between sleep duration and diabetes [25–28], but one found no association [11]. The relationship between sleep patterns and cancer was also mixed.…”

Background This study aimed to assess the relationship between specific nighttime-daytime sleep patterns and prevalence of different chronic diseases in an elderly population. Methods We conducted a community-based cross-sectional study in 4150 elderly Chinese, with an average age of 74 years. Sleep-related variables (nighttime sleep duration, daytime napping and duration) and chronic disease status, including diabetes, cardiovascular diseases (CVD), dyslipidemia cancer and arthritis were collected for the study. Multivariable logistic regression models were used to analyze the relationship between nighttime-daytime sleep patterns and prevalence of chronic diseases. Results Overall prevalence of any of chronic diseases was 83.8%. Nighttime-daytime sleep patterns were defined according to nighttime sleep duration and habitual nappers/non-nappers. Taking the nighttime-daytime sleep pattern “short nighttime sleep with daytime napping” as reference, those with “long nighttime sleep without daytime napping” had higher prevalence of diabetes [OR and 95% CI, 1.35 (1.01–1.80)] and lower prevalence of arthritis [OR and 95% CI, 0.46 (0.33–0.63)]. And those with “long nighttime sleep with daytime napping” had higher prevalence of diabetes [OR and 95% CI, 1.36 (1.05–1.78)] while lower prevalence of cancer [OR and 95% CI, 0.48 (0.26–0.85)] and arthritis [OR and 95% CI, 0.67 (0.51–0.86)]. Further, in habitual nappers, subjects were classified according to duration of nighttime sleep and daytime naps. Compared to “short nighttime sleep with long daytime napping”, individuals with “long nighttime sleep with short daytime napping” had significantly positive association with diabetes prevalence [OR and 95% CI, 1.73 (1.15–2.68)] while border-significantly and significantly negative association with cancer [OR and 95% CI, 0.49 (0.23–1.07)] and arthritis [OR and 95% CI, 0.64 (0.44–0.94)], respectively. Conclusions Elderly individuals with chronic diseases had different nighttime-daytime sleep patterns, and understanding these relationships may help to guide the management of chronic diseases.

“…Short or long sleep durations have been reported to be associated with a higher risk of diabetes mellitus [1][2][3], obesity [4,5], hypertension [6,7], cardiovascular disease (CVD) [8,9] and atherosclerosis [10]. In fact, the mechanisms underlying these relationships are still unclear.…”

Night sleep duration and risk of each lipid profile abnormality in a Chinese population: a prospective cohort study

et al. 2020

Background: To explore the associations between sleep duration and abnormalities in serum lipid levels in a Chinese population. Methods: A prospective study was conducted with 34,260 participants from the general Chinese population. Sleep duration was categorized as ≤5, 6, 7, 8 or ≥ 9 h. Each lipid profile abnormality was defined according to the Chinese Guidelines for the Prevention and Treatment of Dyslipidemia in Adults (2016). The Cox proportional hazards model was used to assess the association between sleep duration and dyslipidemia. Results: Compared with a 7 h sleep duration, long sleep duration (≥9 h) was significantly associated with low highdensity lipoprotein cholesterol (HDL-C) levels (hazard ratio (HR): 1.24; 95% CI: 1.12-1.38). In subgroup analyses, the positive association between long sleep duration and low HDL-C level in men and in the different age groups was more pronounced than the association in women. No significant interactions were observed in the association between sleep duration and each abnormal serum lipid level by sex/age in the study population (P-interaction> 0.05). Conclusions: These findings suggest that long sleep duration is associated with low HDL-C level among the Kailuan community population.

“…Shorter or longer sleep durations have been reported to be associated with a higher risk of diabetes mellitus [1][2][3], obesity [4,5], and hypertension [6,7], and shorter or longer sleep durations have also been suggested to be related to cardiovascular disease (CVD) [8,9] and atherosclerosis [10]. It has been increasingly recognized that sleeping habits, along with other lifestyle habits, such as eating, exercising, smoking, and drinking, are potential risk factors for cardiovascular outcomes.…”
