Analyzing disparity trends for health care insurance coverage among non-elderly adults in the US: evidence from the Behavioral Risk Factor Surveillance System, 1993–2009

Objective

To explore the changing disparities in access to health care insurance in the United States using time-varying coefficient models.

Data

Secondary data from the Behavioral Risk Factor Surveillance System (BRFSS) from 1993 to 2009 was used.

Study design

A time-varying coefficient model was constructed using a binary outcome of no enrollment in health insurance plan versus enrolled. The independent variables included age, sex, education, income, work status, race, and number of health conditions. Smooth functions of odds ratios and time were used to produce odds ratio plots.

Results

Significant time-varying coefficients were found for all the independent variables with the odds ratio plots showing changing trends except for a constant line for the categories of male, student, and having three health conditions. Some categories showed decreasing disparities, such as the income categories. However, some categories had increasing disparities in health insurance enrollment such as the education and race categories.

Conclusions

As the Affordable Care Act is being gradually implemented, studies are needed to provide baseline information about disparities in access to health insurance, in order to gauge any changes in health insurance access. The use of time-varying coefficient models with BRFSS data can be useful in accomplishing this task.

     

Enduring inequality: educational disparities in health among the oldest old in Sweden 1992–2011

Objectives

Although the past two decades have involved changes in the living conditions of the oldest old in Sweden, little is known about how health inequalities have developed in this group during the period. This study explores the educational disparities in a wide range of health outcomes among the oldest old in Sweden between 1992 and 2011.

Methods

The study uses the repeated cross-sectional design of the SWEOLD survey, a nationally representative survey of the oldest old in Sweden with comparable data from 1992, 2002, and 2011. The development of educational disparities in health was tracked across the three waves.

Results

The results show that although the prevalence of most health problems increased during the period, the prevalence of disability in activities of daily living decreased. Despite these changes, educational disparities in health remained largely unaffected.

Conclusions

The results of the study suggest that the association between education and health is remarkably robust. It prevailed into the oldest age groups, was consistently found for a wide range of health problems, and tended to be stable over extended periods of time.

     

Evaluation of a continuing educational intervention for primary health care professionals about nutritional care of patients at home

Objective

Evaluate the effectiveness of a continuing educational intervention on primary health care professionals’ familiarity with information important to nutritional care in a palliative phase, their collaboration with other caregivers, and their level of knowledge about important aspects of nutritional care.

Design

Observational cohort study.

Setting

10 primary health care centers in Stockholm County, Sweden.

Participants

140 district nurses/registered nurses and general practitioners/physicians working with home care.

Intervention

87 professionals participated in the intervention group (IG) and 53 in the control group (CG). The intervention consisted of a web-based program offering factual knowledge; a practical exercise linking existing and new knowledge, abilities, and skills; and a case seminar facilitating reflection.

Measurements

The intervention’s effects were measured by a computer-based study-specific questionnaire before and after the intervention, which took approximately 1 month. The CG completed the questionnaire twice (1 month between response occasions). The intervention effects, odds ratios, were estimated by an ordinal logistic regression.

Results

In the intra-group analyses, statistically significant changes occurred in the IG’s responses to 28 of 32 items and the CG’s responses to 4 of 32 items. In the inter-group analyses, statistically significant effects occurred in 20 of 32 statements: all 14 statements that assessed familiarity with important concepts and all 4 statements about collaboration with other caregivers but only 2 of the 14 statements concerning level of knowledge. The intervention effect varied between 2.5 and 12.0.

Conclusion

The intervention was effective in increasing familiarity with information important to nutritional care in a palliative phase and collaboration with other caregivers, both of which may create prerequisites for better nutritional care. However, the intervention needs to be revised to better increase the professionals’ level of knowledge about important aspects of nutritional care.

     

Age and IQ Explained Working Memory Performance in a RCT with Fatty Fish in a Group of Forensic Inpatients

Objectives

To investigate the effect of a long-term fatty fish intervention on a pure cognitive mechanism important for self-regulation and mental health, i.e. working memory (WM), controlling for age and IQ.

Design

A randomized controlled trial.

Setting

A forensic facility.

Participants

Eighty-four young to middle aged male forensic inpatients with psychiatric disorders.

Intervention

Consumption of farmed salmon or control meal (meat) three times a week during 23 weeks.

Measurement

Performance on WM tasks, both accuracy and mean reaction time, were recorded pre and post intervention.

Results

Performance on a cognitive functioning tasks taxing WM seemed to be explained by age and IQ.

Conclusion

Fatty fish consumption did not improve WM performance in a group of young to middle aged adults with mental health problems, as less impressionable factors such as aging and intelligence seemed to be the key components. The present study improves the knowledge concerning the interaction among nutrition, health and the aging process.

     

Longitudinal Analysis of Outpatient Physician Visits in the Oldest Old: Results of the AgeQualiDe Prospective Cohort Study

Objectives

The aim of this study was to identify determinants of outpatient health care utilization among the oldest old in Germany longitudinally.

Design

Multicenter prospective cohort “Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)” (AgeQualiDe).

Setting

Individuals in very old age were recruited via GP offices at six study centers in Germany. The course of outpatient health care was observed over 10 months (two waves).

Participants

Primary care patients aged 85 years and over (at baseline: n=861, with mean age of 89.0 years±2.9 years; 85–100 years).

Measurements

Self-reported numbers of outpatient visits to general practitioners (GP) and specialists in the past three months were used as dependent variables. Widely used scales were used to quantify explanatory variables (e.g., Geriatric Depression Scale, Instrumental Activities of Daily Living Scale, or Global Deterioration Scale).

Results

Fixed effects regressions showed that increases in GP visits were associated with increases in cognitive impairment, whereas they were not associated with changes in marital status, functional decline, increasing number of chronic conditions, increasing age, and changes in social network. Increases in specialist visits were not associated with changes in the explanatory variables.

Conclusion

Our findings underline the importance of cognitive impairment for GP visits. Creating strategies to postpone cognitive decline might be beneficial for the health care system.

     

Swallowing function and nutritional status in Japanese elderly people receiving home-care services: A 1-year longitudinal study

Objectives

Malnutrition is a serious health concern for frail elderly people. Poor oral function leading to insufficient food intake can contribute to the development of malnutrition. In the present study, we explored the longitudinal association of malnutrition with oral function, including oral health status and swallowing function, in elderly people receiving home nursing care.

Design

Prospective observational cohort study with 1-year follow-up.

Setting

Two mid-sized cities in Fukuoka, Japan from November 2010 to March 2012.

Participants

One hundred and ninety-seven individuals, aged ≥ 60 years, living at home and receiving homecare services because of physical disabilities, without malnutrition.

Measurements

Oral health status, swallowing function, taking modified-texture diets such as minced or pureed foods, nutritional status, cognitive function, and activities of daily living were assessed at baseline. The associations between malnutrition at 1-year follow-up and these related factors were analyzed using a logistic regression model.

Results

Swallowing disorders [risk ratio (RR): 5.21, 95% confidence interval (95% CI): 1.65–16.43] were associated with malnutrition. On the other hand, oral health status did not have a direct association with malnutrition.

Conclusion

Swallowing disorders may be associated with the incidence of malnutrition in elderly people receiving home-care. The findings indicate that maintaining swallowing function may contribute to the prevention of malnutrition in frail elderly people.

     

The inequality of inpatient care net benefit under integration of urban-rural medical insurance systems in China

Background

China has recently made efforts to integrate urban and rural basic medical insurance systems in order to ensure both urban and rural enrollees obtain unified benefits. However, whether the distribution of government healthcare subsides has become more equitable remains unknown. The purpose of this study was to analyze determinants of and inequality in net inpatient care benefits under the integration of urban-rural medical insurance systems in China.

Methods

Data were obtained from a nationally representative household survey, the Fifth National Health Services Survey (2013), conducted in Anhui province. A multiple regression model and concentration index (CI) was used to estimate related factors and inequality of inpatient care net benefits.

Results

Findings indicated that individuals received more inpatient care benefits when urban and rural social healthcare systems were integrated. Factors associated with net benefits included gender, age, marital status, retirement, educational level, history of chronic diseases, health status, willingness to seek inpatient care and per capita income. The rich were found to disproportionately benefit from inpatient care, and the CI of net benefits for integrated insurance enrollees was the lowest among all three available health insurance schemes. These findings indicate that the recent unification of urban-rural social health insurances reduces inequality in net benefits from government subsidies. Some socioeconomic factors, such as per capita income, 60?years of age and over, history of chronic disease and high educational level positively influence inequality.

Conclusion

In China, accelerating the integration of urban and rural medical insurance systems is an effective way to increase equity of benefit in urban and rural areas. Strategies aimed at reducing inpatient benefit inequality must address socioeconomic factors influencing healthcare outcomes.

     

Association of new-onset diabetes mellitus in older people and mortality in Taiwan: A 10-year nationwide population-based study

Objective

Older patients with diabetes mellitus are at a higher risk of developing diabetic macro- and micro-vascular complications and cardiovascular diseases than younger diabetes mellitus patients. However, older diabetes mellitus patients are very heterogeneous in their clinical characteristics, diabetes mellitus-related complications and age at disease onset. This study aimed to evaluate the all-cause mortality rates and adverse health outcomes among older adults with new-onset diabetes mellitus through a nationwide population-based study.

Design

A retrospective cohort study.

Setting

2001-2011 data of the National Health Insurance database.

Population

Nationally representative sample of Taiwanese adults aged 65 years and older with propensity score-matched controls.

Main outcome measures

All-cause mortality and adverse health outcomes.

Results

During the study period, 45.3% of patients in the diabetes mellitus cohort and 38.8% in the non-diabetes mellitus cohort died. The adjusted relative risk for mortality in the diabetes mellitus cohort compared to the non-diabetes mellitus cohort was 1.23 (95% Confidence Interval [CI]=1.16-1.30) for males and 1.27 (95%CI=1.19-1.35) for females. During the follow-up period, 8.9% of the diabetes mellitus cohort and 5.8% of the non-diabetes mellitus cohort developed cardiovascular diseases; the diabetes mellitus cohort had an adjusted relative risk of cardiovascular complications compared to the non-diabetes mellitus cohort of 1.54 (95%CI=1.36-1.75) for men and 1.70 (95%CI=1.43-2.02) for women. The adjusted relative risk of mortality in the patients with hypoglycemia compared to non-hypoglycemia patients in the diabetes mellitus cohort was 2.33 (95%CI=1.81-3.01) for men and 2.73 (95%CI=2.10-3.52) for women after adjustment for age, Charlson comorbidity index, acute coronary syndrome, respiratory disease, cancer, infectious disease and nervous system disease at baseline.

Conclusions

New-onset diabetes in older adults is associated with an increased risk of mortality, and hypoglycemia is an important marker of this association. Individualized care plans stratified by age at onset, duration of disease, comorbidity and functional status, as well as hypoglycemia avoidance, would benefit the management of diabetes in older adults.

     

Frailty index and its relation to falls and overnight hospitalizations in elderly Chinese people: A population-based study

Objectives

To investigate current status of frailty index (FI) defined as deficit accumulation and its relations to falls and overnight hospitalizations in an elderly Chinese population.

Design

A cross-sectional cohort study.

Setting

All of the 31 valiages in Jiang’an township, a typical medium-sized township in Rugao city, China.

Participants

Overall 1773 participants aged 70-84 years were randomly recruited.

Measurements

A FI including symptoms, activities of daily living, co-morbidities, cognitive and psychological function was constructed using 45 health deficits.

Results

The mean of FI was 0.14 in men and 0.19 in women. According to a usual FI cut-point of 0.25, 8.2% of men and 23.2% of women were classified as frail. Literate participants had lower levels of FI than their illiterate counterpart. In men, the FI was positively related to age (r = 0.186, p<.001), with a mean rate of deficit accumulation of 0.032 (on a log scale) per year. Each increment of 0.01 on the FI was associated with significantly increased risks of falls and overnight hospitalizations, with odds ratios of 1.05 (95% CI: 1.03, 1.07) and 1.05 (95% CI: 1.03, 1.08). Similarly, the aforementioned associations were observed in women. Education level moderated the associations of FI with falls in men and women.

Conclusion

Elderly Chinese women were more frail than men. The FI significantly increased with chronological age and was significantly associated with falls and overnight hospitalizations, and education level may play an important role. This study provides preliminary but crucial evidences for future researches on frailty in China.

     

Slow gait speed is an independent predictor of early death in older cancer outpatients: Results from a prospective cohort study

Objective

To assess the predictive value of gait speed for early death in older outpatients with cancer.

Design

Prospective bicentric observational cohort study.

Setting

The Physical Frailty in Elder Cancer patients (PF-EC) study (France).

Participants

One hundred and ninety outpatients with cancer during the first 6 months of follow up in the PF-EC study.

Measurements

The association between usual gait speed over 4 m alone (GS) or included in the short physical performance battery (SPPB) and overall survival within 6 months following a comprehensive geriatric assessment (CGA). A Cox proportional-hazard regression model was performed in non-survivors for clinical factors from the CGA, along with c reactive protein (CRP). Two models were created to assess GS alone and from inclusion in the SPPB.

Results

The mean age was 80.6 years, and 50.5% of the participants were men. Death occurred in 11% (n=22) of the participants within the 6 month follow up period. Of these participants, 98% had solid cancers, and 33% had a metastatic disease. A GS < 0.8 m/s (HR=5.6, 95%CI=1.6-19.7, p=0.007), a SPPB < 9 (HR=5.8, 95%CI=1.6-20.9, p=0.007) and a CRP of 50 mg/l or greater (p<0.0001) were significantly associated with early death in the two multivariate analyses. Cancer site and extension were not significantly associated with early death.

Conclusion

Walking tests are associated with early death within the 6 month follow up period after a CGA independent of cancer site and cancer extension. GS alone < 0.8 m/s is at least as efficacious as the SPPB in predicting this outcome. GS alone could be used routinely as a marker of early death to adapt oncologic therapeutics. Further studies are needed to validate these preliminary data.

     

Quality of Life and Mental Health in Older Adults with Obesity and Frailty: Associations with a Weight Loss Intervention

Objective

To examine the bi-directional associations of a weight loss intervention with quality of life and mental health in obese older adults with functional limitations.

Design

Combined-group analyses of secondary variables from the MEASUR-UP randomized controlled trial.

Setting

Academic medical center.

Participants

Obese community-dwelling men and women (N = 67; age ≥60; BMI ≥30) with functional limitations (Short Physical Performance Battery [SPPB] score of 4–10 out of 12).

Intervention

Six-month reduced calorie diet at two protein levels.

Measurements

Weight, height, body composition, physical function, medical history, and mental health and quality of life assessments (Center for Epidemiologic Studies Depression Scale [CES-D]; Profile of Mood States [POMS], Pittsburgh Sleep Quality Index [PSQI]; Perceived Stress Scale [PSS]; Satisfaction with Life Scale [SWLS]; and Short Form Health Survey [SF-36]) were acquired at 0, 3 and 6 months.

Results

Physical composite quality of life (SF-36) improved significantly at 3 months (β = 6.29, t2,48 = 2.60, p = 0.012) and 6 months (β = 10.03, t2,48 = 4.83, p < 0.001), as did several domains of physical quality of life. Baseline depression symptoms (CES-D and POMS) were found to predict lower amounts of weight loss; higher baseline sleep latency (PSQI) and anger (POMS) predicted less improvement in physical function (SPPB).

Conclusion

The significant bi-directional associations found between a weight loss intervention and mental health/quality of life, including substantial improvements in physical quality of life with obesity treatment, indicate the importance of considering mental health and quality of life as part of any weight loss intervention for older adults.

     

Gesundheitsverhalten von Kleinkindern

Background

Studies have repeatedly pointed out to the relation between socioeconomic background and health behavior. For German samples, immigrant background has been identified as a risk factor for poorer health. Health psychology models emphasize the importance of parental self-efficacy for children’s health behavior.

Objectives

This study examines if parental self-efficacy mediates the relation between the immigrant background, operationalized via language background, and a healthy eating behavior of young children.

Methods

Mediator analyses were performed to test the hypothesis. Data were collected from 184 families with children aged 3 to 4 years via interviews and questionnaires. All families took part in the German parenting program Chancenreich.

Results

Results replicate earlier findings that immigrant background is significantly related to poorer eating habits even when controlling for socioeconomic background. The mediation analyses, however, could show that the negative relation between immigrant background and eating behavior was fully mediated by parental self-efficacy.

Conclusion

Results provide support for intervention program aiming at the enhancement of parental self-efficacy. This might be especially relevant for parents with immigrant background. The goal of such programs should be to reduce social disparities in health outcomes.

     

Responses of Massachusetts hospitals to a state mandate to collect race,ethnicity and language data from patients: a qualitative study

Background

A Massachusetts regulation implemented in 2007 has required all acute care hospitals to report patients' race, ethnicity and preferred language using standardized methodology based on self-reported information from patients. This study assessed implementation of the regulation and its impact on the use of race and ethnicity data in performance monitoring and quality improvement within hospitals.

Methods

Thematic analysis of semi-structured interviews with executives from a representative sample of 28 Massachusetts hospitals in 2009.

Results

The number of hospitals using race, ethnicity and language data internally beyond refining interpreter services increased substantially from 11 to 21 after the regulation. Thirteen of these hospitals were utilizing patient race and ethnicity data to identify disparities in quality performance measures for a variety of clinical processes and outcomes, while 16 had developed patient services and community outreach programs based on findings from these data. Commonly reported barriers to data utilization include small numbers within categories, insufficient resources, information system requirements, and lack of direction from the state.

Conclusions

The responses of Massachusetts hospitals to this new state regulation indicate that requiring the collection of race, ethnicity and language data can be an effective method to promote performance monitoring and quality improvement, thereby setting the stage for federal standards and incentive programs to eliminate racial and ethnic disparities in the quality of health care.

     

An extended cost-effectiveness analysis of schizophrenia treatment in India under universal public finance

Background

Schizophrenia remains a priority condition in mental health policy and service development because of its early onset, severity and consequences for affected individuals and households.

Aims and methods

This paper reports on an ‘extended’ cost-effectiveness analysis (ECEA) for schizophrenia treatment in India, which seeks to evaluate through a modeling approach not only the costs and health effects of intervention but also the consequences of a policy of universal public finance (UPF) on health and financial outcomes across income quintiles.

Results

Using plausible values for input parameters, we conclude that health gains from UPF are concentrated among the poorest, whereas the non-health gains in the form of out-of-pocket private expenditures averted due to UPF are concentrated among the richest income quintiles. Value of insurance is the highest for the poorest quintile and declines with income.

Conclusions

Universal public finance can play a crucial role in ameliorating the adverse economic and social consequences of schizophrenia and its treatment in resource-constrained settings where health insurance coverage is generally poor. This paper shows the potential distributional and financial risk protection effects of treating schizophrenia.

     

Does low body mass index matter? Relationship between body mass index and subjective well-being among long-lived women over 95 years of age

Objectives

To examine the relationship between body mass index (BMI) and subjective well-being (SWB) among long-lived women over 95 years of age and evaluate whether this relationship is mediated by functional ability.

Design

Retrospective cohort study.

Setting

Data from the Rugao longevity cohort, a population-based study in Rugao, China.

Participants

A sample of 342 long-lived women (mean age 97.4 ± 2.1, range 95–107) whose SWB and other covariates were available were included in this study.

Measurements

BMI was calculated as weight in kilograms divided by height in meters-squared (kg/m²). SWB was measured by life satisfaction (LS), positive affect (PA), negative affect (NA) and affect balance (AB). Functional ability was assessed by the Katz Index of Activities of Daily Living (ADL).

Results

According to BMI classification standards for China, the underweight group had lower levels of LS than the normal and overweight groups (28.62 vs. 30.51 and 31.57, respectively; p<.05). Correlation analysis showed that BMI was significantly related to LS (r = 0.166, p<.01). The strength of the BMI and LS association was diminished when ADL was included in the general linear regression models. Mediation analysis revealed that ADL mediated this relationship (effect size = 22.6%). We did not observe significant associations of BMI with other SWB components (PA, NA, and AB).

Conclusion

For long-lived women, low BMI, rather than elevated BMI, is an indicator of poor psychological well-being. The findings call for public health awareness about low body weight in long-lived women, especially in those with physical disabilities when focusing on quality of life.

     

Variability in Repeated Blood Pressure Measurements as a Marker of Frailty

Objectives

Variation in repeated blood pressure measurements may represent a decline in homeostatic mechanisms in blood pressure regulation in response to various internal or external stressors, indicating a frail state. We tested this hypothesis by examining the association between variability in repeated blood pressure measurements (BPV) and frailty status, adjusting for other confounding factors.

Design

A longitudinal cohort study.

Setting

Community centres in all three regions of Hong Kong.

Participants

1156 community-living older adults aged 60 years and over participated in a community geriatric screening program with blood pressure measurements three times a week over one year. Participants were divided into three groups based on variability of repeated blood pressure measurements (low, medium, high) using machine learning methods.

Measurements

Frailty status was assessed using the FRAIL scale. Logistic regression was used to examine cross sectional association between frailty status and BPV adjusting for confounding factors, and also frailty transition with BPV.

Results

In multi-variate models adjusting for co-variates, high BPV was associated with frailty (OR 1.57; 95% CI 1.05-2.37) among all participants; however, this was only significant in women in subgroup analysis. Similar findings were observed when transition to a more frail state was examined over a twelve month period.

Conclusions

The findings of this study support the concept of physiological dysregulation underlying the frail state, and that BPV calculated using machine learning methods may be used as a biomarker of such dysregulation.

     

Case report: surgical removal of a migrated needle in right ventricle of an intravenous drug user

Background

Illicit drug use has become an increasing public health and social concern in the past decades worldwide. Intravenous injection has an elevated risk of infection. Needle embolism is a rare complication of intravenous drug users, Retained broken needles can lead to local complications, such as infection, but they also have the potential to embolize to heart or lung, and lead to serious complications.

Method

We reported a rare case of an intravenous drug user which a retained broken needle fragments in the inferior wall of the right ventricle.

Results

We performed a successful surgery and give our comments and recommendations for illicit drug use worldwide and in China.

Conclusions

Illicit Drug use becomes a global problem because of its health and social harmfulness. To help drug addicts and provide prevention and treatment services are the obligations and responsibilities of all medical workers.

     

Association between physical frailty and quality of life in a representative sample of community-dwelling Swiss older people

Objective

Though the association between physical frailty and health is well established, little is known about its association with other domains of quality of life (QoL). This study investigated the association between physical frailty and multiple domains of QoL in community-dwelling older people.

Design

Cross-sectional study.

Setting and participants

Data of the 2011 annual assessment of 927 older people (age 73-77 years) from the Lc65+ cohort study were used.

Measurements

Physical frailty was assessed by Fried’s five criteria: ‘shrinking’; ‘weakness’; ‘poor endurance, exhaustion’; ‘slowness’; and ‘low activity’. QoL was assessed using 28 items yielding a QoL score and seven domain-specific QoL subscores (Feeling of safety; Health and mobility; Autonomy; Close entourage; Material resources; Esteem and recognition; and Social and cultural life). Low QoL (QoL score or QoL subscores in the lowest quintile) was used as dependent variable in logistic regression analyses adjusted for age and sex (model 1), and additionally for socioeconomic (model 2) and health (model 3) covariates.

Results

Physical frailty was associated with a low QoL score, as well as decreased QoL subscores in all seven specific domains, even after adjusting for socio-economic covariates. However, when performing additional adjustment for health covariates, only the domain Health and mobility remained significantly associated with physical frailty. Among each specific Fried’s criteria, ‘slowness’ had the strongest association with a low QoL score.

Conclusion

Physical frailty is associated with all QoL domains, but these associations are largely explained by poor health characteristics. Longitudinal studies are needed to better understand temporal relationships between physical frailty, health and QoL.

     

Fruit and vegetable intake and physical activity as predictors of disability risk factors in African-American middle-aged individuals

Objective

To investigate fruit and vegetable intake (FVI) and different dimensions of physical activity (PA) as predictors of change in disabilities and other known precursors of progressive disability in a populationbased sample of African Americans.

Design

Longitudinal investigation of the independent associations of reported FVI and PA with six-year changes in disabilities and other known precursors of progressive disability.

Setting

Longitudinal study of a population-representative cohort of late middle-aged African Americans.

Participants

432 cohort participants with complete information on all measures.

Measurements and Analytic Approach

During wave 8 (2008), FVI was measured using 2005 Behavioral Risk Factor Surveillance System questions and PA dimensions using the Yale Physical Activity Survey (YPAS). Disability measures included basic activities of daily living (ADLs) and instrumental ADLs (IADLs); other precursors included measured gait speed, grip strength, and short physical performance battery (SPPB) and reported lower body functional limitations (LBFLs) and FRAIL scale; these were measured at wave 4 (2004) and wave 10 (2010). Residualchange score linear regression was used to identify FVI and PA factors that were independently associated with six-year changes in disability and other precursors.

Results

The study cohort was less active than the YPASdevelopment group. Longitudinally, leisurely walking was independently associated with better ADL, IADL, grip strength, SPPB, LBFL, and frailty outcomes; standing with better IADL and SPPB; intake of vegetables other than carrots, salads, or potatoes with better grip strength and frailty; and fruit juice intake with worse grip strength and frailty.

Conclusions

In this relatively inactive cohort, leisurely walking was associated with multiple beneficial outcomes. Benefits were also seen with vegetables other than potato intake, and fruit juice intake was associated with detrimental effects. This study highlights the importance of finding strategies to help this population increase PA (especially leisurely walking) and intake of whole fruits and vegetables.
