Associations of fruit & vegetable intake and physical activity with poor self-rated health among Chinese older adults.

BACKGROUND: Despite the existing literature highlights the central roles of sociodemographic factors, fruit & vegetable (F&V) intake, and physical activities for maintaining good health, less is known about the associations in the Chinese context. This study attempted to explore the associations of servings of F&V intake and levels of physical activities with poor self-rated health (SRH) among Chinese older adults. METHODS: Data were drawn from the Study on Global Ageing and Adult Health-China (SAGE-China) issued by the World Health Organization and included 7560 respondents aged ≥60 years in China. After screening out the potential confounding factors, multiple logistic regression models were adopted to explore the associations of sociodemographic factors, servings of F&V intake, and levels of physical activities with poor SRH. RESULTS: Among the sample, nearly a quarter reported poor health status. There were significant gender differences in the case of servings of F&V intake and levels of physical activities. Logistic regressions indicated that higher fruit intake was associated with lower likelihood of vigorous level of physical activity as compared to zero intake. Likewise, higher vegetable intake (≥10 servings) was associated with a higher likelihood of vigorous & moderate level of physical activity when compared to lower intake (≤ 4 servings). Higher fruit intake was associated with a lower likelihood of poor SRH. Similarly, vegetable intake (5 servings: AOR = 0.69, 95%CI: 0.58-0.83; 6-9 servings: AOR = 0.72, 95%CI: 0.59-0.87) was significantly associated with poor SRH. Additionally, vigorous level of physical activity (AOR = 0.79, 95%CI: 0.65-0.97) and vigorous fitness/leisure (AOR = 0.57, 95%CI: 0.39-0.84) were significantly associated with poor SRH. CONCLUSION: This study suggested that older adults with high fruit intake had lower probability of performing vigorous & moderate level of physical activity, while those with high vegetable intake had higher probability of performing vigorous & moderate level of physical activity. Likewise, the older adults with high F&V intake and higher probability of performing vigorous level of physical activity, walk/bike activity, and vigorous/moderate fitness/leisure had less likelihood to face the risk for poor SRH outcomes. The appropriate servings of F&V intake and levels of physical activity should be highlighted.

Different Levels of Physical Activity, Physical Health, Happiness, and Depression among Older Adults with Diabetes.

The purpose of this study was to investigate the relationship between different levels of physical activity (light, moderate, and vigorous), physical health, happiness, and depression among older adults with diabetes. Using data from the National Social Life, Health and Aging Project (NSHAP) Wave 3, the results indicate that moderate and/or vigorous physical activity is more effective than light physical activity for promoting physical health and happiness and lowering depression of older adults with diabetes. This study suggests that activity professionals and therapists working with older adults with diabetes need to encourage their participation in physical activity as well as adjust a level of physical activity intensity that is tailored to participants' needs and expectations.

Low Levels of Physical Activity and Sedentary Behavior in Adults with Intellectual Disabilities.

Adults with intellectual disabilities (ID) are more likely to lead sedentary lifestyles and have low levels of physical activity (LLPA). The present study investigated the prevalence of reported LLPA and time spent watching TV in adults with ID and identified the associated factors for these behaviors. The proxy informants of 1618 adults with ID completed the surveys regarding their health behaviors. Multiple logistic regressions were employed for LLPA and multiple linear regressions for time spent watching TV. About 60% of adults with ID had LLPA and average time spent watching TV was 3.4 h a day. Some characteristics and health and function variables were identified as associated factors. While engaging in community activities and involvement in Special Olympics were inversely associated with LLPA, they were not associated with time spent watching TV. Attending day/educational programs or being employed were associated with spending less time watching TV. Findings highlight differential factors associated with LLPA versus TV-watching behavior in adults with ID. Hence, a key strategy aimed at increasing physical activity includes promoting participation in social and community activities, while targeted activities for reducing sedentary behavior might focus on providing day programs or employment opportunities for adults with ID.

Young women's physical activity from one year to the next: What changes? What stays the same?

The Majority of women do not meet recommended physical activity (PA) guidelines. Assessment on changes in PA patterns among young, healthy US women was therefore performed. PA changes were assessed from self-reported PA at baseline (year 1) and follow-up (year 2). Participants [N=127] aged 18-30 years had completed a randomized controlled aerobics trial. A two-sample test of proportions tested the sample changes in PA; a paired t test assessed the within-person changes. A multivariate logistic regression model assessed the demographic predictors of meeting PA levels in year 2 (6 months post-intervention). Women who met the recommended PA used a combination of leisure and lifestyle PA at both timepoints. In year 2, attaining the recommended PA levels through leisure-time PA increased, while work-related and active transit PA decreased. Leisure-time physical activity at moderate and vigorous levels of intensity is recommended to ensure that young women meet the recommended PA levels and obtain health benefits.
