Brief summary

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.

Inclusion criteria

1. hyper- or hypothyroidism. 2. taking prescribed medications (such as growth hormone, testosterone, or progesterone) known to alter body composition. 3. any condition that prevented them from completing our questionnaires or the functional capacity test (e.g., amputee, nonambulatory even with the use of a walker or a cane, blind, or deaf).

Design outcomes

Primary

Measure	Time frame	Description
Skeletal muscle mass index	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

Measure	Time frame	Description
Sleep quality	one day	Using Pittsburgh Sleep Quality Index to record the sleep quality
Level of physical activity	one day	Using 7-d recall physical activity questionnaire to evaluate general physical activity in the past 7 days.
Sleep duration	one day	Recording the sleep time at night and daytime napping separately.
Body composition	one day	Using Bioelectrical Impedance Analysis to measure fat percentage in all subjects.
