Self-reported vision impairment and its contribution to disability among older adults.
ABSTRACT To examine contributions of self-reported vision impairment to disability by persons 65 years and older.
We used data from the National Health and Nutrition Examination Survey (NHANES IV; 1999-2008; weighted N = 6,550). The four-staged Nagi model of the disability process, incorporating biomarkers, disease, and physical functioning, was used as a framework to guide variable selection. An unadjusted ordinal logistic regression model testing effects of vision on daily-life activities was compared with models that controlled covariates associated with each stage of the disability model.
Where significant effects of poor vision remained, the strongest effect was found for doing leisure activities at home (OR = 5.29; 95% CI [3.14, 8.90]).
Results suggest the importance of considering multiple health factors when formulating comprehensive vision rehabilitation interventions.

ABSTRACT: OBJECTIVE: The purpose of this cross-sectional study was to determine the extent and manner in which mobility is related to quality of life (QOL) in a representative sample of older adults. METHOD: Two models were assessed using structured equation modeling. The first hypothesized that mobility would have a direct effect on QOL along with other variables, including; number of health conditions and satisfaction with functional capacity, life essentials (e.g., transport, access to health services, and conditions of living space) and personal relationships. The second hypothesized that mobility would have its greatest influence on QOL through satisfaction with functional capacity. RESULTS: While both models found that mobility and all three measures of life satisfaction were significantly associated with QOL, goodness of fit indices were higher for the second model. DISCUSSION: The findings from this study suggest that mobility interventions designed to enhance QOL should address satisfaction with functional capacity as well.Journal of Aging and Health 06/2013; · 1.56 Impact Factor

ABSTRACT: In the context of population aging, visual impairment has emerged as a growing concern in public health. However, there is a need for further research into the relationship between visual impairment and chronic medical conditions in the elderly. The aim of our study was to examine the relationship between visual impairment and three main types of co-morbidity: chronic physical conditions (both at an independent and additive level), mental health and cognitive functioning.BMC Public Health 08/2014; 14(1):815. · 2.32 Impact Factor

ABSTRACT: To explore whether the accumulation of sensory difficulties predicts fear of falling (FOF), and whether the traits correlate with each other regardless of familial factors. Self-reported hearing, vision and balance difficulties, and FOF were assessed using structured questionnaires at the baseline and after a 3-year follow-up in 63- to 76-year-old women (n = 434). Among the women without FOF at baseline (n = 245), 41% reported FOF at follow-up. Increasing numbers of sensory difficulties at baseline predicted higher incidence of FOF. The relationship between accumulated sensory difficulties and FOF was not mediated by familial factors. The accumulation of multiple sensory difficulties may hinder older people from receiving compensatory information about body position and environment, thus jeopardizing a person's confidence in maintaining a balanced position. Regular screening of sensory functions followed by appropriate actions may prevent the development of FOF, and thus contribute to prevention of falls and promotion of healthy aging.Journal of Aging and Health 07/2013; · 1.56 Impact Factor
