Technology-based Fall Risk Assessments for Older Adults in Low-income Settings

The goal of this observational study is to examine the associations among fall risk appraisal, body composition, and physical activity in older adults in low-income settings. The main questions it aims to answer are: * What is the feasibility of recruitment (e.g., how many older adults need to be screened to recruit the sample?), especially during the COVID-19 pandemic, and acceptability of technologies and procedures for use among older adults in low-income settings? * What are the the dynamic relationships between fall risk appraisal, body composition, physical activity, and behavioral changes related to fear of falling? Participants will: * complete questionnaires about their characteristics, socio-demographic, medical history, cognition, depressive symptoms, anxiety, and fear of falling. * participate in static and dynamic balance tests, body composition measurement and handgrip strength test. * wear an accelerometer for physical activity assessment for 7 consecutive days.
