To describe which dietary nutrient variables are related to subjective and objective habitual sleep and subjective and objective napping.
Participants were 459 post-menopausal women enrolled in the Women's Health Initiative. Objective sleep was estimated using one week of actigraphy. Subjective sleep was prospectively estimated with a daily sleep diary. Dietary nutrients were calculated from food frequency questionnaires.
The most significant correlations were with subjective napping, including (from strongest to weakest): total fat, calories, saturated fat, monounsaturated fat, trans fat, water, proline, serine, tyrosine, phenylalanine, valine, cholesterol, leucine, glutamic acid, ash, isoleucine, histidine, sodium, tryptophan, protein, threonine, cystine, methionine, phosphorous, polyunsaturated fat, animal protein, aspartic acid, arginine, lysine, alanine, caffeine, riboflavin, gamma-tocopherol, glycine, retinol, delta-tocopherol, Vitamin D, and selenium. Actigraphic nocturnal sleep duration was negatively associated with total fat, monounsaturated fat, trans fat, saturated fat, polyunsaturated fat, calories, gamma-tocopherol, cholesterol, and alpha-tocopherol-eq.
Actigraphic total sleep time was negatively associated with intake of fats. Subjective napping, which may be a proxy for subjective sleepiness, was significantly related to fat intake as well as intake of meat.
描述哪些饮食营养变量与主观和客观习惯性睡眠以及主观和客观小睡有关。
参与者为参加妇女健康倡议的 459 名绝经后妇女。使用一周的活动记录仪来估计客观睡眠。主观睡眠通过每日睡眠日记前瞻性估计。从食物频率问卷中计算出饮食营养素。
与主观小睡的相关性最显著，包括（从最强到最弱）：总脂肪、卡路里、饱和脂肪、单不饱和脂肪、反式脂肪、水、脯氨酸、丝氨酸、酪氨酸、苯丙氨酸、缬氨酸、胆固醇、亮氨酸、谷氨酸、灰分、异亮氨酸、组氨酸、钠、色氨酸、蛋白质、苏氨酸、胱氨酸、蛋氨酸、磷、多不饱和脂肪、动物蛋白、天冬氨酸、精氨酸、赖氨酸、丙氨酸、咖啡因、核黄素、γ-生育酚、甘氨酸、视黄醇、δ-生育酚、维生素 D 和硒。活动记录仪记录的夜间睡眠时间与总脂肪、单不饱和脂肪、反式脂肪、饱和脂肪、多不饱和脂肪、卡路里、γ-生育酚、胆固醇和α-生育酚当量呈负相关。
活动记录仪总睡眠时间与脂肪摄入呈负相关。主观小睡可能是主观嗜睡的替代指标，与脂肪摄入以及肉类摄入密切相关。
