Dietary Patterns and Self-reported Incident Disability in Older Adults.

ABSTRACT:

Background or objectives

Disability in older adults is associated with low quality of life and higher mortality. Diet may be a potentially important public health strategy for disability prevention in aging. We examined the relations of the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets to functional disability in the Rush Memory and Aging Project.

Methods

A total of 809 participants (mean age = 80.7 ± 7.2 years, 74% female) without functional disability at baseline were followed for an average of 5.3 years. Standardized measures for self-reported disability including, activities of daily living ADL), instrumental ADL, and mobility disability were assessed annually. The diet scores were computed based on a validated food frequency questionnaire administered at baseline.

Results

In Cox proportional hazards models adjusted for age, sex, education, smoking, physical activity, and total calories, the second (hazard ratio = 0.75, 95% CI: 0.60-0.95) and third tertiles (hazard ratio = 0.67, 95% CI: 0.53-0.86) of MIND diet scores had lower rates of ADL disability compared to the lowest tertile (p for trend = .001), whereas only the third tertiles of the Mediterranean (hazard ratio = 0.73, 95% CI: 0.57-0.94) and DASH (hazard ratio = 0.75, 95% CI: 0.59-0.95) diets were significantly associated with ADL disability. Instrumental ADL disability was inversely and linearly associated with the MIND diet score only (p for trend = .04). Mobility disability was associated with the MIND (p for trend = .02), Mediterranean (p for trend = .05) and DASH (p for trend = .02) diet scores.

Conclusion

These findings are encouraging that diet may be an effective strategy for the prevention of functional disability in older adults.

Project description:BackgroundBioelectrical impedance analysis (BIA)-derived phase angle is expected to be an efficient prognostic marker of health adverse events with aging as an alternative of muscle mass. We aimed to examine the predictive ability of phase angle for incident disability in community-dwelling elderly and determine the optimal cut-off values.MethodsCommunity-dwelling elderly aged ≥65 years (n = 4452; mean age = 71.8 ± 5.3 years, 48.3% women) without disability at baseline participated in this prospective cohort study. Phase angle and appendicular skeletal muscle mass (ASM) were examined using a multi-frequency BIA at baseline. Other potential confounding factors (demographics, cognitive function, depressive symptoms, medications, and physical performance) were also assessed. Incident disability was monitored on the basis of long-term care insurance certification.ResultsOver a follow-up of 24 months, 4.0% (n = 174) experienced disability, with an overall incidence rate of 20.6 per 1000 person-years. The Cox hazard regression analysis showed that phase angle, as a continuous variable, was independently associated with incident disability after adjusting the covariates [male: hazard ratios (HRs) = 0.61, 95% confidence interval (CI) = 0.37-0.98; female: HR = 0.58, 95% CI = 0.37-0.90], although body mass index adjusted ASM was not. Receiver operating characteristic analysis indicated moderate predictive abilities of phase angle for incident disability [male: area under the receiver operating characteristic curve (AUC) = 0.76, 95% CI = 0.70-0.83; female: AUC = 0.71, 95% CI = 0.65-0.76], while those of body mass index adjusted ASM were low (male: AUC = 0.59, 95% CI = 0.521-0.66; female: AUC = 0.58, 95% CI = 0.52-0.63). Multivariate Cox regression analysis showed that low phase angle categorized by cut-off value (male, ≤4.95°; female, ≤4.35°) was independently related to increased risk of incident disability (HR = 1.95, 95% CI = 1.37-2.78).ConclusionsLower phase angle independently predicts the incident disability separately from known risk factors. BIA-derived phase angle can be used as a valuable and simple prognostic tool to identify the elderly at risk of disability as targets of preventive treatment.

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:Older adults are more susceptible to higher inflammatory levels and depression. Moreover, diet may influence inflammation as well as depression but no previous study examined whether inflammatory dietary patterns are related to depression in an older population. To investigate the longitudinal association between inflammatory dietary patterns (using reduced rank regression (RRR)) and depressive symptoms in a population sample of Italian older adults.We included 827 participants (aged?65years) at baseline in 1998. Follow-up measurements were collected after 3, 6 and 9years. We used RRR to identify inflammatory dietary patterns at baseline. The Centre for Epidemiologic Studies Depression (CES-D) scale was used to assess depressive symptoms by using continuous scores and depression by using a cut-off point (CES-D?20).We identified two inflammatory dietary patterns using different sets of response variables. Dietary pattern I was related to inflammatory markers C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor ? and was characterized by high intakes of refined grains, sweet snacks, pasta and rice. After full adjustment for confounders, no longitudinal association was found when comparing extreme quartiles of this dietary pattern and depressive symptoms (Q1vs Q4, model 4: B=0.04, 95% CI: -0.06, 0.13) or depression (Q1vs Q4, model 4: OR=0.90, 95% CI: 0.55, 1.45). Dietary pattern II was related to inflammatory markers CRP, IL-18, IL-1?, IL-1 receptor antagonist and was characterized by high intakes of pasta, sugar-sweetened beverages, processed meat and chocolate and sweets. When comparing extreme quartiles, this dietary pattern was not longitudinally associated with depressive symptoms (Q1vs Q4, model 4: B=-0.04, 95% CI: -0.13, 0.05) but an inverse association was found for depression (Q1vs Q4, model 4: OR=0.56, 95% CI: 0.40, 0.94).Our study does not support the hypothesis that dietary patterns linked to inflammatory markers are associated with higher depressive symptoms and higher depression incidence. However, dietary intake in our population of older adults was quite homogeneous which makes it difficult to show clear associations.
