Trends and variation in mild disability and functional limitations among older adults in Norway, 1986-2008.

ABSTRACT: An increase in the number of older adults may raise the demand for health and care services, whereas decreasing prevalence of disability and functional limitations among them might counteract this demographic effect. However, the trends in health are inconsistent between studies and countries. In this article, we estimated the trends in mild disability and functional limitations among older Norwegians and analyzed whether they differ between socio-demographic groups. Data were obtained from repeated cross-sectional surveys conducted in 1987, 1991, 1995, 2002, 2005, and 2008, in total 4,036 non-institutionalized persons aged 67 years or older. We analyzed trends using multivariate logistic regression. On average, the age-adjusted trend in functional limitations was -3.3% per year, and in disability 3.4% per year. The risk for functional limitations or disability was elevated for women compared to men, for married compared to non-married, and was inversely associated with educational level The trends were significantly weaker with increasing age for disabilities, whereas none of the trends differed significantly between subgroups of sexes, educational level or marital status. Both functional limitations free and disability-free life expectancy appeared to have increased more than total life expectancy at age 67 during this period. The analysis suggests downward trends in the prevalence of mild disability and functional limitations among older Norwegians between 1987 and 2008 and a compression of lifetime in such health states. The reduced numbers of older people with disability and functional limitations may have restrained the demand for health and care services caused by the increase in the number of older adults.

Project description:BackgroundSelf-reported disability has a strong negative impact on older people's quality of life and is often associated with the need for assistance and health care services. Resistance training (RT) has been repeatedly shown to improve muscle function (e.g. strength) and functional capacity (e.g. gait speed, chair-rise) in older adults with functional limitations. Nevertheless, it is unclear whether such objectively assessed improvements translate into a reduction in self-reported disability.ObjectivesTo assess: i) whether and to what extent RT interventions have an effect on self-reported disability in older adults (≥65 years) with functional limitations or disability; and ii) whether the effects on self-reported disability are associated with changes in objective measures of muscle strength and functional capacity across studies.MethodsPubMed, Embase, Web of Science, CINAHL and SPORTDiscus electronic databases were searched in June 2018. Randomized controlled trials reporting effects of RT on self-reported disability/function in ≥65 year-old adults with defined, functional limitations or self-reported disability were eligible. Data on self-reported disability/function were pooled by calculating adjusted standardized mean differences (SMD) using Hedges'g. Likewise, effect sizes for three secondary outcomes: knee extensor muscle strength; gait capacity; and lower body functional capacity were calculated and fit as covariates in separate meta-regressions with self-reported disability as the dependent factor.ResultsFourteen RCTs were eligible for the primary meta-analysis on self-reported disability. The total number of participants was 651 (intervention n = 354; control n = 297). A significant moderate positive effect of RT was found (SMD: 0.59, 95% CI: 0.253 to 0.925, p = 0.001). Between-study heterogeneity was present (I2 statistic = 75,1%, p < 0.001). RT effects on objective measures of lower body functional capacity were significantly associated with effects on self-reported disability (Adj. R2 = 99%, p = 0.002, n = 12 studies), whereas no significant associations with gait capacity or knee extensor strength were found.ConclusionsThis review provides evidence that RT has a moderate positive effect on self-reported disability/function in old people with or at risk for disability. The effects are strongly associated with effects on objective measures of lower body functional capacity.

Project description:BackgroundAs our society ages, improving medical care for an older population will be crucial. Discrimination in healthcare may contribute to substandard experiences with the healthcare system, increasing the burden of poor health in older adults. Few studies have focused on the presence of healthcare discrimination and its effects on older adults.ObjectiveWe aimed to examine the relationship between healthcare discrimination and new or worsened disability.DesignThis was a longitudinal analysis of data from the nationally representative Health and Retirement Study administered in 2008 with follow-up through 2012.ParticipantsSix thousand and seventeen adults over the age of 50 years (mean age 67 years, 56.3 % female, 83.1 % white) were included in this study.Main measuresHealthcare discrimination assessed by a 2008 report of receiving poorer service or treatment than other people by doctors or hospitals (never, less than a year=infrequent; more than once a year=frequent). Outcome was self-report of new or worsened disability by 2012 (difficulty or dependence in any of six activities of daily living). We used a Cox proportional hazards model adjusting for age, race/ethnicity, gender, net worth, education, depression, high blood pressure, diabetes, cancer, lung disease, heart disease, stroke, and healthcare utilization in the past 2 years.Key resultsIn all, 12.6 % experienced discrimination infrequently and 5.9 % frequently. Almost one-third of participants (29 %) reporting frequent healthcare discrimination developed new or worsened disability over 4 years, compared to 16.8 % of those who infrequently and 14.7 % of those who never experienced healthcare discrimination (p < 0.001). In multivariate analyses, compared to no discrimination, frequent healthcare discrimination was associated with new or worsened disability over 4 years (aHR = 1.63, 95 % CI 1.16-2.27).ConclusionsOne out of five adults over the age of 50 years experiences discrimination in healthcare settings. One in 17 experience frequent healthcare discrimination, and this is associated with new or worsened disability by 4 years. Future research should focus on the mechanisms by which healthcare discrimination influences disability in older adults to promote better health outcomes for an aging population.
