Impact of Perceived Safety and Barriers on Physical Activity Levels in Community-Dwelling Older Adults During the COVID-19 Pandemic in Singapore: A Cross-Sectional Mixed Methods Study.

This descriptive cross-sectional mixed methods study conducted in Singapore aimed to describe community-dwelling older adults' differences in physical activity (PA) based on perceived safety to exercise, barriers to PA, and preferred modes of PA during a pandemic. Out of 268 older adults, 25.4% felt unsafe to exercise during the pandemic.

Factors influencing fear of falling in community-dwelling older adults in Singapore: a cross-sectional study.

Background: Fear of falling (FoF) has far-reaching implications including activity restriction, functional decline and reduced quality of life. It is a common consequence of falls but may be present even in non-fallers. This study aimed to determine the factors associated with FoF in a segment of Singapore's community-dwelling older adults.

Does the multidimensional grading system (BODE) correspond to differences in health status of patients with COPD?

Study Objectives: To verify whether and to what extent the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index correlates with a disease-specific index of health status in patients with COPD.

Design: Cross-sectional study.

Setting: University-affiliated hospital.
