简要总结
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.
详细描述
The investigators will use a cross-sectional design to address aims. The investigators will administer the study instruments which consist of objective and subjective measures. Participants will complete questionnaires about their characteristics, socio-demographic, medical history, cognition, depressive symptoms, anxiety, and fear of falling.
Balance performance will be assessed by the BTrackS Balance System (BBS). This test consists of four, 20 seconds trials. For each trial, the participants will stand as still as possible on the BBP with hands on their hips, and eye closed. This test consists of four trials. This test will take about 5-10 minutes.
Body composition will be assessed using a bioelectrical impedance analysis (BIA): InBody S10. The BIA InBody S10 measures fat mass, muscle mass and body water levels. There are no risks, no dunking, no pinching, no discomfort associated with the use of bioelectrical impedance analysis. Test duration is 1-2 minutes.
Physical Activity (PA) will be measured by activity monitoring devices. All participants will wear the ActiGraph GT9X Link wireless activity monitor (ActiGraph LLC.), a tri-axial accelerometer, on the non-dominant wrist for 7 consecutive days.

结局指标
主要结局
Acceptability of using technologies in low-income older adults
时间窗: Through study completion, an average of 2 years
The acceptability of the technologies and procedures will be examined based on an evaluation form (e.g., what the participants thought about the questionnaires and technology) and participants' recommendations.
Balance Performance
时间窗: Once at baseline, an average of 4 minutes
Balance performance will be assessed using the BTrackS Balance test.
Fear of Falling
时间窗: Once at baseline, an average of 10 minutes
Fear of falling will be assessed using the Short Fall Efficacy Scale International (short FES-I) with 7 items.The minimum score possible is 7 and the maximum possible score is 28. Scores of 7-8 indicate "low concern," scores of 9-13 indicate "moderate concern," and scores of 14-28 indicate "high concern."
Feasibility of recruitment of low-income older adults
时间窗: Through study completion, an average of 2 years
The investigators will assess the ability to recruit the participants by tracking the number of days and time spent to recruit the sample.
Maladaptive fall risk appraisal
时间窗: Once at baseline, an average of 5 minutes
A condition in which there is a discrepancy between perceived fall risk (levels of fear of falling) and physiological fall risk (balance performance). Fear of falling will be assessed using the Short Fall Efficacy Scale International (short FES-I) with 7 items and balance performance will be assessed using the BTrackS Balance test. Maladaptive fall risk will be plotted on a electronic graph as the interaction between balance performance on the X-axis and fear of falling on the Y-axis.
Body Composition
时间窗: Once at baseline, an average of 2 minutes
Body composition will be assessed using a direct segmental multi-frequency bioelectrical impedance analysis (BIA): InBody s10 device.
Time spent in each physical activity intensity domain
时间窗: 7 days
Participants will wear the ActiGraph GT9X Link wireless activity monitor (ActiGraph LLC.), a tri-axial accelerometer, on the non-dominant wrist for 7 consecutive days.This device will assess the time (minutes) spent in light, moderate, and vigorous physical activity domains throughout the 7-day assessment period.
次要结局
- Depression(Once at baseline, an average of 10 minutes)
