Longitudinal associations between self-rated health and performance-based physical function in a population-based cohort of older adults.

ABSTRACT:

Background

Although self-rated health (SRH) and performance-based physical function (PPF) are both strong predictors of mortality, little research has investigated the relationships between them. The objective of this study was to evaluate longitudinal, bi-directional associations between SRH and PPF.

Methods

We evaluated longitudinal associations between SRH and PPF in 3,610 adults aged 65-89 followed for an average of 4.8 (standard deviation [SD]: 4.4) years between 1994 and July 2011 in the Adult Changes in Thought study, a population-based cohort in the Seattle area. SRH was assessed with a single-item question in the ACT study. Participants were asked at each evaluation to rate their health as "excellent", "very good", "good", "fair", or "poor" in response to the question "In general, how would you rate your health at this time". PPF scores (ranging from 0-16, with higher indicating better performance) included walking speed, chair rises, grip strength, and balance.

Results

At the baseline visit, participants averaged 74.5 (SD: 5.8) years of age and 2,115 (58.6%) were female. In multivariable linear mixed models, PPF declined with age, with more rapid decreases associated with very good, good, and fair (vs. excellent) baseline SRH. Adjusted annual change in PPF was -0.17 points (95% confidence interval [CI]: -0.19, -0.15) for individuals with excellent baseline SRH and -0.21 points (95% CI: -0.22, -0.19) for participants with fair SRH. In multivariable generalized linear mixed models, lower baseline PPF quartiles were associated with lower odds of excellent/very good/good SRH at age 75, however, differences between baseline PPF quartiles diminished with age.

Conclusions

These results suggest that less than excellent SRH predicts decline in physical functioning, however, poor physical functioning may not predict change in SRH in a reciprocal fashion. SRH provides a simple assessment tool for identifying individuals at increased risk for decline in physical function.

Project description:BackgroundDespite the existing literature highlights the central roles of sociodemographic factors, fruit & vegetable (F&V) intake, and physical activities for maintaining good health, less is known about the associations in the Chinese context. This study attempted to explore the associations of servings of F&V intake and levels of physical activities with poor self-rated health (SRH) among Chinese older adults.MethodsData were drawn from the Study on Global Ageing and Adult Health-China (SAGE-China) issued by the World Health Organization and included 7560 respondents aged ≥60 years in China. After screening out the potential confounding factors, multiple logistic regression models were adopted to explore the associations of sociodemographic factors, servings of F&V intake, and levels of physical activities with poor SRH.ResultsAmong the sample, nearly a quarter reported poor health status. There were significant gender differences in the case of servings of F&V intake and levels of physical activities. Logistic regressions indicated that higher fruit intake was associated with lower likelihood of vigorous level of physical activity as compared to zero intake. Likewise, higher vegetable intake (≥10 servings) was associated with a higher likelihood of vigorous & moderate level of physical activity when compared to lower intake (≤ 4 servings). Higher fruit intake was associated with a lower likelihood of poor SRH. Similarly, vegetable intake (5 servings: AOR = 0.69, 95%CI: 0.58-0.83; 6-9 servings: AOR = 0.72, 95%CI: 0.59-0.87) was significantly associated with poor SRH. Additionally, vigorous level of physical activity (AOR = 0.79, 95%CI: 0.65-0.97) and vigorous fitness/leisure (AOR = 0.57, 95%CI: 0.39-0.84) were significantly associated with poor SRH.ConclusionThis study suggested that older adults with high fruit intake had lower probability of performing vigorous & moderate level of physical activity, while those with high vegetable intake had higher probability of performing vigorous & moderate level of physical activity. Likewise, the older adults with high F&V intake and higher probability of performing vigorous level of physical activity, walk/bike activity, and vigorous/moderate fitness/leisure had less likelihood to face the risk for poor SRH outcomes. The appropriate servings of F&V intake and levels of physical activity should be highlighted.

Project description:Background: Whether multiple nutritional deficiencies have a synergic effect on mobility loss remains unknown. This study aims to evaluate associations between multi-nutritional deficits and physical performance evolution among community-dwelling older adults. Methods: We included 386 participants from the Multidomain Alzheimer Preventive Trial (MAPT) (75.6 ± 4.5 years) not receiving omega-3 polyunsaturated fatty acid (PUFA) supplementation and who had available data on nutritional deficits. Baseline nutritional deficits were defined as plasma 25 hydroxyvitamin D <20 ng/ml, plasma homocysteine >14 μmol/L, or erythrocyte omega-3 PUFA index ≤ 4.87% (lower quartile). The Short Physical Performance Battery (SPPB), gait speed, and chair rise time were used to assess physical performance at baseline and after 6, 12, 24, 36, 48, and 60 months. We explored if nutrition-physical performance associations varied according to the presence of low-grade inflammation (LGI) and brain imaging indicators. Results: Within-group comparisons showed that physical function (decreased SPPB and gait speed, increased chair rise time) worsened over time, particularly in participants with ≥2 nutritional deficits; however, no between-group differences were observed when individuals without deficit and those with either 1 or ≥2 deficits were compared. Our exploratory analysis on nutritional deficit-LGI interactions showed that, among people with ≥2 deficits, chair rise time was increased over time in participants with LGI (adjusted mean difference: 3.47; 95% CI: 1.03, 5.91; p = 0.017), compared with individuals with no LGI. Conclusions: Accumulated deficits on vitamin D, homocysteine, and omega-3 PUFA were not associated with physical performance evolution in older adults, but they determined declined chair rise performance in subjects with low-grade inflammation.

Project description:Background:Self-rated Health (SRH) is regarded as a simple and valid measure of a person's health status, given its association to adverse health outcomes, including low physical performance in older populations. However, studies investigating these associations in low- and middle-income settings are scarce, especially for middle-aged populations. Understanding the validity of SRH in relation to objective health measures in low-income populations could assist in decision making about health policy and strategies, especially in under-resourced settings. Objective:Assess the relationship between SRH and physical performance measures in middle-aged and older women in a low-income setting of Brazil. Methods:This is a cross-sectional study of 571 middle-aged (40-59 years old) and older (60-80 years old) women living in Parnamirim and Santa Cruz in the Northeast region of Brazil. Participants reported their health status and were allocated to the "SRH good" or "SRH poor" groups. The physical performance evaluation included: handgrip strength, one-legged balance with eyes open and closed and chair stand test. The relationship between SRH and physical performance for middle-aged and older women was assessed by quantile regression (modeling medians) adjusted for potential confounders (age, socioeconomic variables, body mass index, menopause status, age at first birth, parity, chronic conditions and physical activity). Results:Middle-aged women from the "SRH good" group presented better physical performance with 1.75 kgf stronger handgrip strength (95% CI [0.47-3.02]; p = 0.004), 1.31 s longer balance with eyes closed ([0.00-2.61]; p = 0.030), and they were 0.56 s faster in the chair stand test ([0.18-0.94]; p = 0.009) than those who reported "SRH poor". No association was found for balance with eyes open. For older women, there was no evidence of associations between physical performance and SRH. Conclusion:This study showed that SRH is significantly associated with objective measures of physical performance in a sample of low-income middle-aged women. SRH can be an important tool to indicate the need for further evaluation of physical performance among middle-aged women and can be particularly useful for low-income communities.

Project description:ObjectivesThe population of Estonia has one of the lowest life expectancies and health statuses in Europe. This is reflected in a lower perception of health among older adults. This study focuses on the role of health behaviour (smoking, alcohol consumption, physical activity and nutrition) in self-rated health, accounting for sociodemographic characteristics, activity limitations and long-term illnesses as well as satisfaction with life of older Estonian men and women.DesignWe use representative cross-sectional data from Wave 4 of the Estonian Survey of Health, Ageing and Retirement in Europe, conducted mainly in 2011.ParticipantsFrequencies, ?2 tests and logistic regression models include respondents aged 50 years and older, with no upper age limit (n=6660).ResultsMen have 20% higher odds (CI 1.02 to 1.43) of poor self-rated health. Being of foreign origin (OR 1.48; CI 1.24 to 1.77), having a basic (2.50; CI 2.06 to 3.00) or secondary (1.71; CI 1.43 to 2.04) education, being retired (2.00; CI 1.65 to 2.44) or staying at home (1.49; CI 1.16 to 1.93) and having activity limitations (3.25; CI 2.77 to 3.80) or long-term illnesses (4.78; CI 4.08 to 5.60) are related to poor self-rated health. Never being involved in vigorous (2.30; CI 1.90 to 2.79) or moderate physical activity (1.41; CI 1.02 to 1.94), and consuming legumes and eggs less frequently (1.25; CI 1.08 to 1.45) is associated with poorer self-rated health. Lower satisfaction with life accounts for some of the variation (2.28; CI 1.92 to 2.71).ConclusionsThere is a strong cumulative effect of one's previous life course on the self-rated health of older adults in Estonia, suggesting that public health policies have long-term consequences rather than immediate consequences. Health services supporting health behaviours and targeting vulnerable population groups with specific sociodemographic characteristics and health problems may influence self-rated health for some. Public health services emphasising social activities or psychological aspects may be most successful in improving self-rated health of older Estonians through satisfaction with life.
