Physical Activity and Falls Among a National Cohort of Older Veterans.

ABSTRACT: The more than 20 million U.S. veterans have a history of physical activity engagement but face increasing disability as they age. Falls are common among older adults, but there is little evidence on veterans' fall risk. We conducted a retrospective cohort study using 48,643 observations from 14,831 older (?65 years) Americans from the 2006-2014 waves of the Health and Retirement Study. Veterans reported more noninjurious falls (26.6% vs. 24.0%, p < .002), but fewer fall-related injuries (8.9% vs. 12.3%, p < .001) than nonveterans. In adjusted analyses, for each 5-year increase in age, the odds of a noninjurious fall were greater for veterans (odds ratio [OR] = 1.05, 95% confidence interval [CI] = [1.01, 1.10]) and, among those with regular physical activity, the odds were lower for veterans compared with nonveterans (OR = 0.89; 95% CI = [0.81, 0.99]). For veterans, physical activity engagement may prove a particularly effective mechanism for reducing the aging-related risks associated with falls and fall injuries.

The more than 20 million U.S. veterans have a history of physical activity engagement but face increasing disability as they age. Falls are common among older adults, but there is little evidence on veterans' fall risk. We conducted a retrospective cohort study using 48,643 observations from 14,831 older (≥65 years) Americans from the 2006-2014 waves of the Health and Retirement Study. Veterans reported more noninjurious falls (26.6% vs. 24.0%, <i>p</i> < .002), but fewer fall-related injuries ( ...[more]

Project description:Background and objectivesHousing is one of the main places where falls occur; however, few studies have examined housing environmental factors driving fall risk. This study aimed to explore the associations between housing environmental factors and falls in China.Research design and methodsThe study included data of middle-aged and older adults aged ≥45 years from 4 waves of the China Health and Retirement Longitudinal Study. We assessed 7 housing environmental factors: building materials, toilet types, household tidiness, household cooking fuels, and access to electricity, running water, and bathing facilities. Based on these, we divided housing environments into 3 types: good (0-2 poor factors), moderate (3-5 poor factors), and poor (6-7 poor factors). Falls incidence (yes or no) was self-reported during the survey period. We applied the Cox proportional hazard model to estimate the associations, adjusting for a set of covariates such as sociodemographic characteristics, lifestyles, and disease status.ResultsA total of 12,382 participants were analyzed, and the incidence of falls was 31.7%. According to the fully adjusted model, having a squatting toilet (hazard ratio [HR] = 1.14, 95% confidence interval [CI] = 1.03-1.26), household untidiness (HR = 1.09, 95% CI = 1.01-1.18), and solid fuel use for cooking (HR = 1.10, 95% CI = 1.02-1.18) were associated with a higher risk of falls (ps < .05), compared to their counterparts. We found a linear relationship between housing environments and falls (p for trend = .001). Specifically, moderate (HR = 1.16, 95% CI = 1.06-1.27) and poor housing environments (HR = 1.21, 95% CI = 1.08-1.34) were associated with a higher risk of falls compared to a good housing environment.Discussion and implicationsAmong middle-aged and older Chinese adults, a better household environment, including sitting toilets, tidy living conditions, and clean fuel use for cooking, may reduce the risk of falls. The evidence from our study suggests the need to implement age-friendly housing environments to prevent falls and disability in an aging society.

Project description:ImportanceFalls and fall-related injuries are common among older adults. Older adults are recommended to undertake 150 to 300 minutes of physical activity per week for health benefits; however, the association between meeting the recommended level of physical activity and falls is unclear.ObjectivesTo examine whether associations exist between leisure-time physical activity and noninjurious and injurious falls in older women.Design, setting, and participantsThis population-based cohort study used a retrospective analysis of the Australian Longitudinal Study on Women's Health (ALSWH). ALSWH participants born from 1946 to 1951 who completed follow-up questionnaires in 2016 (aged 65-70 years) and 2019 (aged 68-73 years) were included. Statistical analysis was performed from September 2022 to February 2023.ExposureSelf-reported weekly amounts (0, 1 to <150, 150 to <300, ≥300 minutes) and types of leisure-time physical activity, including brisk walking and moderate- and vigorous-intensity physical activity, in the 2016 survey.Main outcome and measuresNoninjurious and injurious falls in the previous 12 months reported in the 2019 survey. Associations between leisure-time physical activity and falls were quantified using directed acyclic graph-informed multinomial logistic regression and presented in odds ratios (ORs) and 95% CIs.ResultsThis study included 7139 women (mean [SD] age, 67.7 [1.5] years). Participation in leisure-time physical activity at or above the level recommended by the World Health Organization (150 to <300 min/wk) was associated with reduced odds of noninjurious falls (150 to <300 min/wk: OR, 0.74 [95% CI, 0.59-0.92]; ≥300 min/wk: OR, 0.66 [95% CI, 0.54-0.80]) and injurious falls (150 to <300 min/wk: OR, 0.70 [95% CI, 0.56-0.88]; ≥300 min/wk: OR, 0.77 [95% CI, 0.63-0.93]). Compared with women who reported no leisure-time physical activity, those who reported brisk walking (OR, 0.83 [95% CI, 0.70-0.97]), moderate leisure-time physical activity (OR, 0.81 [95% CI, 0.70-0.93]), or moderate-vigorous leisure-time physical activity (OR, 0.84 [95% CI, 0.70-0.99]) had reduced odds of noninjurious falls. No statistically significant associations were found between the types of leisure-time physical activity and injurious falls.Conclusions and relevanceParticipation in leisure-time physical activity at the recommended level or above was associated with lower odds of both noninjurious and injurious falls. Brisk walking and both moderate and moderate-vigorous leisure-time physical activity were associated with lower odds of noninjurious falls.
