Sleep deprivation is frequently associated with an unhealthy diet. So far, most studies used reported sleep duration. We assessed the associations between objectively measured sleep duration and dietary intake.
Cross-sectional study conducted between 2009 and 2013 on 1910 participants (49.5% women, 58.3 ± 11.0 years) living in Lausanne, Switzerland. Total sleep time (TST) was assessed using polysomnography and categorized into <7, 7-9 and >9 hours/day. Total energy, macro and micronutrients intake, dietary adequacy scores and compliance to Swiss dietary recommendations were assessed.
There were 60.6%, 37.2% and 2.2% of the participants in the categories <7, 7-9 and >9 h/day, respectively. Body mass index was higher in the >9 h/d sleep category. After multivariate adjustment, significant (p < 0.05) differences were found between sleep categories regarding total carbohydrates (46.6 ± 8.6, 46.0 ± 8.8 and 48.1 ± 8.0% of total energy intake for <7, 7-9 and >9 h/day, respectively), mono and disaccharides (22.7 ± 8.0, 22.4 ± 8.3 and 25.2 ± 8.8), and total fat (33.9 ± 6.4, 34.7 ± 6.9 and 34.2 ± 5.8). No association was found for total energy intake, other nutrients, dietary adequacy scores, dietary patterns or compliance to dietary guidelines. The differences in mono and disaccharides were found in women and the differences in total fat in men, although sex-diet intake interactions were not significant. Sensitivity analyses excluding participants with sleep apnea, using quartiles of TST or subjective sleep duration yielded similar conclusions.
Little if no associations were found between objectively measured TST and dietary intake in a Swiss general adult population. The associations with total carbohydrate, mono and disaccharide and total fat intake deserve further investigation.
睡眠不足通常与不健康的饮食有关。迄今为止，大多数研究都使用报告的睡眠时间。我们评估了客观测量的睡眠时间与饮食摄入之间的关联。
这是一项在 2009 年至 2013 年期间在瑞士洛桑的 1910 名参与者（49.5%为女性，58.3±11.0 岁）中进行的横断面研究。使用多导睡眠图评估总睡眠时间（TST），并分为<7、7-9 和>9 小时/天。评估总能量、宏量和微量营养素摄入、膳食充足评分和遵守瑞士膳食建议的情况。
参与者中<7、7-9 和>9 h/d 分别占 60.6%、37.2%和 2.2%。>9 h/d 睡眠组的体重指数较高。在多变量调整后，睡眠时间类别之间在总碳水化合物（<7、7-9 和>9 h/d 分别为总能量摄入的 46.6±8.6、46.0±8.8 和 48.1±8.0%）、单糖和双糖（22.7±8.0、22.4±8.3 和 25.2±8.8）和总脂肪（33.9±6.4、34.7±6.9 和 34.2±5.8）方面存在显著差异（p<0.05）。总能量摄入、其他营养素、膳食充足评分、膳食模式或遵守膳食指南没有相关性。在女性中发现了单糖和双糖的差异，在男性中发现了总脂肪的差异，尽管性别-饮食摄入的相互作用不显著。排除睡眠呼吸暂停患者、使用 TST 四分位数或主观睡眠时间的敏感性分析得出了类似的结论。
在瑞士一般成年人群中，客观测量的 TST 与饮食摄入之间几乎没有关联。与总碳水化合物、单糖和双糖以及总脂肪摄入的关联值得进一步研究。
