This study aimed to examine personal and social environmental correlates of the physical activity habit of middle-aged and older adults, using Chinese square dancing as a natural exploratory example. Participants were 385 adults aged ≥45 years (93% female), who habitually danced on squares or parks of three old districts of Guangzhou. Multinomial logistic regression was used to identify personal, social, psychological, and behavioral correlates of multiyear dance. Old age, high education, sufficient leisure time, and stable social environmental factors were associated with persistent dancing, whereby education (relative risk ratio [RRR] = 1.64, 95% confidence interval [1.05, 2.57]) and social engagement (RRR = 1.66, 95% confidence interval [1.05, 2.63]) showed the largest effects. Participants dancing ≤1 year were least satisfied with their social relationships than their counterparts dancing 1–5 years (RRR = 0.68) or over 5 years (RRR = 0.58). Physical activity promotion for older adults should adapt from culturally appropriate group activities and leverage community social resources to encourage voluntary participation, particularly for low-educated older women.

This study examined associations of perceived and objectively measured neighborhood environmental attributes with leisure-time sitting for transport among middle-to-older aged Japanese adults.


Data were collected using a postal survey of 998 adults aged 40 to 69 years. Generalized linear modeling with a gamma distribution and a log link was used to examine associations of perceived (International Physical Activity Questionnaire-Environmental module) and Geographic Information Systems (GIS)-derived built environment attributes with self-reported leisure-time sitting for transport.


Mean leisure-time sitting time for transport was 20.4 min/day. After adjusting for potential confounders, perceived higher residential density, GIS-measured higher population density, better access to destinations, better access to public transport, longer sidewalk length, and higher street connectivity, were associated significantly with lower sitting time for transport.


Residents living in neighborhoods with attributes previously found to be associated with more walking tended to spend less time sitting for transport during leisure-time. The health benefits of walkability-related attributes may accrue not only through increased physical activity, but also through less sedentary time.
