VivienLauYW - A Cross-sectional Study of Insomnia and Daily Nutrient Intake.

This study attempts to address the association between nutrients and insomnia. This literature is part of my dissertation. Chapter one addressed the history of sleep and insomnia; Chapter two to four addressed the age, mood, pain, and sleep hygiene, caffeine, drug an alcohol effect on sleep. Nutrients effect on insomnia was discussed in Chapter five and six. Insomnia is a common sleep disorder and a major public health issue. Insomnia could be classified into three subtypes: Difficulty in Initiating Sleep (DIS), Difficulty in Maintaining Sleep (DMS), and Early Morning Wakening (EMW). My study was conducted in 138 adolescents and 173 adults in a community-based cross-sectional observation. Information of daily nutrient intake was obtained by a self-administrated 3-day food dietary, the assessment of insomnia symptom was obtained by a standard sleep questionnaire such as Insomnia Severity Index (ISI), and the assessment of anxiety and depression was obtained by commonly used scale such as Hospital Anxiety and Depression Scale (HADS). Associations are found between insomnia and nutrient components. Decreased intake of saturated fat, carbohydrate, vitamin A, vitamin D, and vitamin E are associated with insomnia subtype DIS and overall insomnia syndrome in adult and in adolescent. Decreased intake of saturated fat is found associated with insomnia subtype DMS and decreased intake of carbohydrate is found associated with insomnia subtype EMW.
