Insomnia has become a major public health issue in recent times. Although quality of sleep is affected by environmental, psychophysiological, and pharmacological factors, diet and nutrient intake also contribute to sleep problems. This study investigated the association between nutrient intake and co-morbid symptoms associated with sleep status among selected adults. Subjects in this study included 87 men and women aged 21-45 years. Presence of insomnia was assessed using the Insomnia Screening Questionnaire, and dietary intake was measured over three consecutive days by dietary survey. Descriptive analysis, ANOVA, and Chi-Square tests were performed to compute and interpret the data. Approximately 60% of the participants were insomniacs. People with insomnia consumed significantly lesser quantities of nutrients as compared to normal sleepers. Differences in intakes of energy, carbohydrates, folic acid, and B(12) were highly significant (P < 0.002). Further, intakes of protein, fat, and thiamine were significantly different (P < 0.021) between insomniacs and normal sleepers. The nutrient intake pattern of the insomniacs with co-morbid symptoms was quite different from that of the normal sleepers. Based on these results, it is probable that there is an association between nutrition deficiency, co-morbid symptoms, and sleep status. More studies are required to confirm these results.
失眠症已成为当前主要的公共卫生问题之一。尽管睡眠质量受到环境、心理生理和药理学因素的影响，但饮食和营养摄入也会导致睡眠问题。本研究调查了营养摄入与特定成年人睡眠状况相关的共病症状之间的关联。本研究的对象包括 87 名年龄在 21-45 岁之间的男性和女性。采用失眠筛查问卷评估失眠症的存在，通过连续三天的饮食调查来测量膳食摄入。采用描述性分析、方差分析和卡方检验来计算和解释数据。大约 60%的参与者患有失眠症。与正常睡眠者相比，失眠症患者摄入的营养物质明显较少。能量、碳水化合物、叶酸和 B(12)的摄入量差异具有高度显著性（P < 0.002）。此外，失眠症患者和正常睡眠者的蛋白质、脂肪和硫胺素摄入量也存在显著差异（P < 0.021）。伴有共病症状的失眠症患者的营养摄入模式与正常睡眠者明显不同。基于这些结果，营养缺乏、共病症状和睡眠状况之间可能存在关联。需要进一步的研究来证实这些结果。
