Background & Hypothesis

The study examined the prevalence of physical activity and sedentary behaviours, and the relationship between these variables and health-related quality of life (HRQoL) in the general population of Singapore as part a cross-sectional and population-based survey.

Methods

Physical activity and sedentary behaviour were assessed via the Global Physical Activity Questionnaire (GPAQ), while physical and mental HRQoL was assessed via the Short Form Health Survey (SF-12v2). Multivariable logistic regression models were utilized to examine sociodemographic correlates of physical activity (insufficient vs sufficient physical activity) and sedentary behaviour (<7 hours/day vs ≥7 hours/day). Multivariable linear regressions were conducted to examine the association between physical activity and sedentary behaviour with physical and mental HRQoL.

 

Results

A total of 2895 participants were included in the analyses. 83.3% of respondents had sufficient physical activity. Age, ethnicity, income, and having one chronic physical condition were associated with physical activity. 47.7% reported that they had sedentary behaviour of ≥7 hours/day. Older age was related to lower likelihood of sedentary behaviour, while being single, having higher income, obesity and multimorbidity were associated with higher likelihood of sedentary behaviour. Insufficient physical activity was significantly associated with physical but not mental HRQoL.

Discussion & Conclusion

About 17% of population do not meet the minimum requirements for physical activity, while around half the population spent a large time sedentary. Policymakers should promote moderate physical activity and encourage the breaking up of prolonged sedentary periods within middle- and high-income groups. Increased leisure-time exercise should be encouraged for those in the lower income group
