Social Support for Physical Activity Over 9 Years in Adults Aged 60-65 Years at Baseline.

Physical activity is a leading determinant of health and well-being in older adults; however, participation is low. Social support can significantly influence physical activity uptake and maintenance; however, most research is cross-sectional and does not differentiate among types of support. The current study assessed four types of social support for physical activity reported over 9 years by adults aged 60-65 at baseline (n = 1,984). Data were collected using a mail survey at four time points. Data were analyzed using linear mixed models. The most common type of support was emotional, with 25% of participants reporting this often/very often. Total support for activity declined by 16% across the 9 years (p < .001). Companionship had the greatest decline among types (17%-18%, p < .001). More work is needed to understand the factors contributing to the decline in support and how to enable access to support for physical activity in older adults.

The Relationship between Social Support for Physical Activity and Physical Activity across Nine Years in Adults Aged 60-65 Years at Baseline.

Physical activity is consistently recognized as a key component of healthy aging. The current study aimed to investigate the prospective association between social support specific for physical activity (SSPA) and physical activity across nine years among adults aged 60-65 years at baseline (n = 1984). An observational longitudinal design was used, with mail surveys administered to a population-based sample across four waves. SSPA was measured using a score ranging from 5-25, and physical activity was assessed as time spent in walking, or engaging in moderate and vigorous activity, during the previous week. Data were analyzed using linear mixed-effects models. The results demonstrated a positive significant relationship between SSPA and physical activity, accounting for sociodemographic and health variables. Each unit of increase in SSPA was associated with 11 extra minutes of physical activity per week (p < 0.001). There was a significant interaction between SSPA and wave at the final timepoint, such that the relationship was weaker (p = 0.017). The results highlight the value of even small increases in SSPA. SSPA could be targeted to promote physical activity among older adults, but may be more impactful in young-old adults. More research is needed to understand impactful sources of SSPA, underlying mechanisms between SSPA and physical activity, and potential moderation by age.

Frequency of Physical Activity Done with a Companion: Changes Over Seven Years in Adults Aged 60+ Living in an Australian Capital City.

Objectives:This study examined how often adults 60+ years were physically active with a partner, close family, friends, and neighbors, over 7 years. Methods: Data from 2062 adults living in an Australian capital city were collected using a mail survey at four time points and analyzed using multinomial logistic regression. Results: A partner was the most frequent companion at all time points. From baseline to 7 years, the greatest decline was activity with family 1-4x/month (.79 [.64-.98]) and ≥5x/month (.54 [.36-.80]). There were also decreases in activity 1-4x/month with a partner (OR = .75, [.62-.92]), friends (.55 [.44-.68]), and neighbors (.79 [.64-.98]). Physical activity with friends or neighbors ≥5x/month did not decline. Discussion: Findings extend understanding of physical activity and activity companions among older adults. More research is needed to understand factors contributing to changes in activity done with companions.
