Objective Research on aging has received considerable attention in medicine, public health and social sciences in recent decades. This study aimed to investigate predictors of life satisfaction and healthy aging with focus on gender differences among elderly population in Brunei. Methods Cross-sectional study on elderly population aged 50 to 75, recruited by proportionate sampling. Multivariate linear regression analysis stratified by gender, was applied. Results 45.6% of the variance explaining life satisfaction of elderly women were strongly associated with self-perceived health, social relationship, and education level. For elderly men, 26.3% of the variance of life satisfaction was predicted by physical functioning or disability, and social relationship. Musculoskeletal discomfort, and mental and emotional issues were significantly higher in elderly women. Conclusions This report benefits policymakers and related stakeholders for care of elderly by maintaining or further promoting social interactions, active engaging elderly in health maintenance, and physical and mental functioning.

Purpose: Level of satisfaction is significantly influenced by health-related factors across human life course. Multidimensions of health and other factors such as religion and culture influence life satisfaction that differ across different societies. Prior research shows that there are variations in the relationship between health factors and life-satisfaction between Western and Asian countries. Nevertheless, it is still unknown to what extend health factors are related to life satisfaction in Brunei Darussalam—a country with small population but increasing in proportion of elderly population. This study aimed to explore health determinants of life satisfaction among elderly population in Brunei Darussalam. Methods: A cross-sectional study on a sample of 645 adults aged above 50 years, recruited nationally. Descriptive statistics and multivariate regression analysis were applied. Results: A robust model (R2=49.3%, alpha>0.7) suggested that life satisfaction in this population could largely be explained by musculoskeletal pain, difficulty to perform daily activities, psychological and emotional issues, and family support. Gender has significant moderating effects on this relationship. Conclusion: Impacts of life satisfaction from health, social, cultural, and related perspectives were discussed. These findings in this research may contribute to ongoing multi-sectorial efforts to design a comprehensive model of elderly care to achieve high quality of life.
