Associations Between Self-Reported Sleep Duration and Sarcopenia in Community-Dwelling Older Adults

1. BACKGROUNDS: Currently, elderly people comprise more than 10% of the total Taiwanese population. However, within the context of self-reported sleep duration and health risks, research into the association between sleep duration and body composition changes in older people is limited. It is important to gain an understanding of such an association of older people to estimate the public health burden. 2. OBJECTIVES: To assess the association between self-reported sleep duration and sarcopenia as well as obesity in community-dwelling older adults. 3. HYPOTHESIS: Self-reported sleep duration is associated with prevalence of sarcopenia and obesity in community-dwelling older adults. 4. DESIGN: A cross-sectional investigation. 5. SETTING: Communities in Zhongzheng district, Taipei. 6. PARTICIPANTS: Four hundred and forty-eight community-dwelling adults (224 men and 264 women) aged 65 years and older. 7. MEASUREMENTS: The investigators evaluated self-reported sleep duration by deriving from the Pittsburgh Sleep Quality Index and 7-d recall physical activity diary. Skeletal muscle mass was estimated by the predicted equation from a bioelectrical impedance analysis measurement. The Groningen Activity Restriction Scale and the Chinese Geriatric Depression Screening Scale were used to evaluate physical disability and depression, respectively.

Treatment and study plan

Primary outcomes

Skeletal muscle mass index

Time frame: one day

Using Bioelectrical Impedance Analysis to measure skeletal muscle mass (kg) and further calculate skeletal muscle mass index to investigate the prevalence of sarcopenia.

Secondary outcomes

Sleep quality

Time frame: one day

Using Pittsburgh Sleep Quality Index to record the sleep quality
Level of physical activity

Time frame: one day

Using 7-d recall physical activity questionnaire to evaluate general physical activity in the past 7 days.
Sleep duration

Time frame: one day

Recording the sleep time at night and daytime napping separately.
Body composition

Time frame: one day

Using Bioelectrical Impedance Analysis to measure fat percentage in all subjects.
