Social Network Factors Affect Nutrition Risk in Middle-Aged and Older Adults: Results from the Canadian Longitudinal Study on Aging.

OBJECTIVES: To determine which social network, demographic, and health-indicator variables are associated with SCREEN-8 (nutrition risk) scores at two time points, three years apart, using data from the Canadian Longitudinal Study on Aging. DESIGN: A retrospective cross-sectional study. SETTING AND PARTICIPANTS: 17051 Canadians aged 45 years and older with data from baseline and first follow-up of the Canadian Longitudinal Study on Aging. MEASUREMENTS: Nutrition risk was measured using SCREEN-8. Social network factors included social network size, frequency of contact with social network members, social participation, social support, self-rated social standing, and household income. Demographic variables included age, sex assigned at birth, marital status, educational attainment, and living situation (alone or with others). Health-indicator variables included depression, disability, and self-rated general health, mental health, healthy aging, and oral health. Multivariable linear regression was used to analyze the relationship between the social network, demographic, and health-indicator variables and SCREEN-8 scores at two time points, three years apart. RESULTS: Among the social network variables, individuals with higher social participation, self-rated social standing, and social support had higher SCREEN-8 scores at baseline and follow-up. Among the demographic variables, individuals who were single or widowed, compared to married or partnered, had lower SCREEN-8 scores at both time points. For the health-indicator variables, individuals who screened negative for depression, and those with higher self-rated general health, healthy aging, and oral health had higher SCREEN-8 scores at both time points. At baseline, as age increased, SCREEN-8 scores also increased. CONCLUSION: Individuals with low social participation, low social standing, and low social support may be at increased nutrition risk and should be proactively screened by healthcare professionals. Interventions and community programs designed to increase levels of social participation and foster social support may help to reduce the prevalence of nutrition risk.

Water-based therapeutic exercise in stroke: a scoping review.

PURPOSE: To (1) describe the state of the literature on water-based therapeutic exercise (WBTE) for people living with stroke, (2) describe the content and structure of interventions, (3) summarize the effects of interventions described in the literature, and (4) identify gaps in the literature limiting application and implementation. MATERIALS AND METHODS: Scoping review methodology described by Arksey and O'Malley (2005) and Levac et al. (2010). Electronic databases were searched for articles with eligibility criteria including: (1) adult stroke survivors (18 years or older) of any type (ischemic/hemorrhagic) or stage (acute/chronic) in any setting, and (2) the study intervention involved WBTE to address a post-stroke deficit. RESULTS: 40 articles were included in this review. Five trials had a treatment control, 20 had an active comparison. Calculated intervention effect sizes demonstrated a strong effect of WBTE on balance and gait related outcomes in 80% of controlled and comparison trials. CONCLUSIONS: This scoping review highlights common parameters of WBTE interventions and provides an inventory of the differences in the treatment approaches utilized in this population. Opportunities for future work include the development of a standardized treatment protocol, qualitative or mixed methodology research, and greater inclusion of more individuals with more severe stroke-related impairments. IMPLICATIONS FOR REHABILITATIONWater-based therapeutic exercise is an approach that may allow stroke survivors to carry out challenging activities in a safe and accessible environment.Water-based interventions for stroke survivors appear to have a beneficial impact on walking and balance.Given that an aquatic environment offers an opportunity for individuals with more significant physical impairments to carry out early practice of walking and balance related tasks, clinicians should explore the feasibility and effectiveness for this subset of stroke survivors.
