Abstract Background Physical activity is related to health-related quality of life, but little evidence from multiple waves of panel data in Asian countries area available. This study aims to explore the impacts of different degree of regular exercise on the trajectories of physical and mental dimensions of health-related quality of life (HRQOL) for community-dwelling Taiwanese adults during 2006–2014. Methods Data were derived from the “Landseed Integrated Outreaching Neighborhood Screening (LIONS)” study, with 6182 adults enrolled at the baseline and subsequently followed up to three times till 2014. Linear mixed-effects modeling approach was employed to evaluate the growth curve models of HRQOL (with 16,281 observations) by linear & quadratic time effects, regular exercise (5-level moderate-intensity physical activity), and major influential factors of HRQOL. Results Regular exercise showed significantly positive dose-response effects on physical HRQOL (β =1.27~2.54), and regular exercise of 150 min or more showed positive effects on mental HRQOL (β = 1.55~2.03). Besides, irregular exercise could also improve both physical and mental HRQOL (β = 1.27 & β = 0.87). However, such effects were not significant over time (at time slope) on HRQOL. In addition, physical and mental HRQOL improved across time (β = 1.01 and 1.49, respectively), but the time quadratic effect would significantly offset a little bit on physical dimension (β = − 0.22). Moreover, being female, increasing age, living alone, or poorer health status were related to lower physical HRQOL; and being younger, living alone, or poorer health status were associated with lower mental HRQOL. Conclusions The positive dose-response relationship between regular exercise and HRQOL or its domains was demonstrated for community-dwelling Taiwanese adults. Thus, a regular exercise habit (better ≧150 min per week) is advised for community-based healthcare professionals and the government to incorporate into health promotion strategies and plans.
