Metabolic syndrome and arthritis among Mexican American older adults: findings from a 23-year follow-up.

To examine the sex differences in the relationship of metabolic syndrome (MetS) criteria with arthritis and symptomatic arthritis among Mexican American older adults aged ≥ 65 without self-reported arthritis at baseline over 23-years of follow-up. Participants (N = 1447) were from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1993/94-2016). Measures included MetS criteria, arthritis defined as self-reported physician-diagnosed arthritis, socio-demographics, morbidities, depressive symptoms, pain on weight-bearing, cognitive and physical function, handgrip strength, mobility, and activities of daily living (ADLs) limitations. Symptomatic arthritis was defined as self-reported arthritis and having ≥ 1 of the following: pain, mobility limitation, or limited ADLs. At baseline, the mean age was 72.6years and 730 (50.5%) of our participants werefemales. Female participants with 2 and 3 MetS criteria had greater odds of arthritis [odds ratio (OR) = 1.77, 95% Confidence Interval (Cl) = 1.28-2.45 and OR = 2.68, 95% CI = 1.69-4.27, respectively) and symptomatic arthritis (OR = 1.74, 95% Cl = 1.24-2.44 and OR = 3.27, 95% CI = 2.04-5.26, respectively) after controlling for covariates. Male participants with 2 and 3 MetS criteria had greater odds of arthritis (OR = 1.65, 95% Cl = 1.14-2.39 and OR = 2.52, 95% CI = 1.51-4.19, respectively) and symptomatic arthritis (OR = 1.93, 95% Cl = 1.30-2.86 and OR = 2.98, 95% CI = 1.62-5.47, respectively) after controlling for covariates. Both females and males with pain on weight-bearing had greater odds of arthritis than those without pain. At 23-years of follow-up, Mexican American older adults with MetS have an increased risk of arthritis and symptomatic arthritis. Early MetS screening and management may reduce arthritis in this population at high risk of disability.

Effectiveness and Implementation of an EnhanceFitness Physical Activity Intervention Specifically in Adults With Arthritis: A RE-AIM Evaluation.

This study evaluated the effectiveness of the evidence-based, EnhanceFitness (EF) physical activity (PA) intervention in improving arthritis symptoms, physical and mental function, and PA in adults with arthritis. This was a community-based, randomized, controlled effectiveness trial that switched to a nonrandomized controlled trial. Participants were sedentary/low-active adults, aged ≥18 years, with self-reported physician-diagnosed arthritis, who were assigned to an immediate or delayed group (12-week, wait-list control group). Classes were held thrice weekly for 12 weeks at 17 community sites in 4 urban and 5 rural West Virginia counties. Data were collected at baseline, 12 weeks, and 24 weeks. The RE-AIM Framework evaluated EF's: (1) reach (enrollment); (2) effectiveness (outcomes); (3) adoption (proportion of sites/instructors that delivered EF); (4) implementation (attendance, fidelity, adverse events, and satisfaction); and (5) maintenance (EF continuation). Outcomes were analyzed using linear mixed-effects regression. There were 323 adults with a mean age of 68.3 years (range 27-95). Reach was 74%; site and instructor adoption rates were 100% and 55%, respectively; attendance (1.8 sessions per week) and fidelity were good; injury rate was low (3.8%); participants were highly satisfied and experienced improvements in arthritis symptoms and physical function; and 27% of instructors and 18% of sites continued EF. EnhanceFitness was safe and effective in improving arthritis symptoms and physical function in sedentary/low-active adults with arthritis, across the adult age spectrum, under real-world conditions, in both urban and rural communities.Clinical Trial Registration: NCT00526201.

Arthritis, physical function, and disability among older Mexican Americans over 23 years of follow-up

ABSTRACT Objective Arthritis is a common chronic condition in the ageing population. Its impact on physical function varies according to sociodemographic and race/ethnic factors. The study objective was to examine the impact of arthritis on physical function and disability among non-disabled older Mexican Americans over time. Design A 23-year prospective cohort study of 2230 Mexican Americans aged 65 years and older from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1993/94–2016). The independent variable was self-reported physician-diagnosed arthritis, and the outcomes included Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), mobility, Short Physical Performance Battery (SPPB), and handgrip strength. Covariates were sociodemographic, medical conditions, body mass index, depressive symptoms, and cognitive function. General linear mixed models were performed to estimate the change in SPPB and muscle strength. General Equation Estimation models estimated the odds ratios (OR) of becoming ADL- or IADL- or mobility – disabled as a function of arthritis. All variables were used as time-varying except for sex, education, and nativity. Results Overall, participants with arthritis had higher odds ratio (OR) of any ADL [OR = 1.35, 95% Confidence Interval (CI) = 1.09–1.68] and mobility (OR = 1.34, 95% CI = 1.18–1.52) disability over time than those without arthritis, after controlling for all covariates. Women, but not men, reporting arthritis had increased risk for ADL and mobility disability. The total SPPB score declined 0.18 points per year among those with arthritis than those without arthritis, after controlling for all covariates (p-value < .010). Conclusions Our study demonstrates the independent effect of arthritis in increasing ADL and mobility disability and decreased physical function in older Mexican Americans over 23-years of follow-up.

The burden for knee osteoarthritis among Chinese elderly: estimates from a nationally representative study

To estimate the burden of knee osteoarthritis (OA) among Chinese population. Individuals with symptomatic knee OA based on self-reported physician-diagnosed arthritis and presence of knee pain were identified in China Health and Retirement Longitudinal Study. Severity of knee OA was divided into three categories: mild, moderate and severe, according to knee pain severity. We estimated sex-specific years lived with disability (YLD) and YLD rate (per 100,000 population) by multiplying the prevalence of knee OA with appropriate disability weight (DW) and examined associations between several key sociodemographic factors and YLDs. Among 17,459 subjects (52.1% women; mean age 59.1 years) included in this analysis, prevalence of mild, moderate and severe knee OA was 1.5%, 3.3%, and 3.9%, respectively. The total number of YLDs for knee OA in China was 4,149,628, and YLDs per 100,000 population was 968. Female sex, older age, rurality, lower education, and lower gross domestic production (GDP) per capita were associated with high YLDs rates for knee OA, respectively. The North and East regions of China had the lowest YLD rate per 100,000 population for knee OA (631 and 699), followed by South-central (858), Northeast (878), and Northwest (1502) regions. Southwest region had the highest YLD rate from knee OA (1653). In this nationally representative sample, we demonstrated a high burden from knee OA among Chinese population. YLD rate for knee OA varied significantly according to sociodemographic factors. Our study calls for an urgent need for health policy support and cost-effective preventive strategies in China.

Healthcare Providers’ Recommendations for Physical Activity among US Arthritis Population: A Cross-Sectional Analysis by Race/Ethnicity

Introduction We examined racial/ethnic disparities in healthcare providers' recommendations for physical activity among individuals with arthritis and evaluated this association among groups of individuals who adhered to physical activity guidelines and those who did not. Methods With a cross-sectional design based on Behavioral Risk Factor Surveillance System, we analyzed individuals with self-reported physician-diagnosed arthritis, ≥18 years of age (n = 83,376). Outcome variable was healthcare providers' recommendations for physical activity. Race/ethnicity was categorized as African American, Hispanic, and White. Associations were examined using multivariate logistic regression. Results African Americans (Adjusted OR: 0.66; 95% CI: 0.55–0.79) and Hispanics (Adjusted OR: 0.68; 95% CI: 0.56–0.83) were less likely to receive providers' recommendations. Conclusions Although the importance of physical activity to improve health outcomes for adults with arthritis, as well as providers' influence on individuals' behavior change, is well established, providers are less likely to recommend physical activity to minorities. Further studies are required to identify the causes for this quality-of-care issue.

Screening for depression in arthritis populations: an assessment of differential item functioning in three self-reported questionnaires.

To determine if persons with arthritis differ systematically from persons without arthritis in how they respond to questions on three depression questionnaires, which include somatic items such as fatigue and sleep disturbance. We extracted data on the Centers for Epidemiological Studies Depression (CES-D) scale, the Patient Health Questionnaire-9 (PHQ-9), and the Kessler-6 (K-6) scale from three large population-based national surveys. We assessed items on these questionnaires for differential item functioning (DIF) between persons with and without self-reported physician-diagnosed arthritis using multiple indicator multiple cause models, which controlled for the underlying level of depression and important confounders. We also examined if DIF by arthritis status was similar between women and men. Although five items of the CES-D, one item of the PHQ-9, and five items of the K-6 scale had evidence of DIF based on statistical comparisons, the magnitude of each difference was less than the threshold of a small effect. The statistical differences were a function of the very large sample sizes in the surveys. Effect sizes for DIF were similar between women and men except for two items on the Patient Health Questionnaire-9. For each questionnaire, DIF accounted for 8% or less of the arthritis-depression association, and excluding items with DIF did not reduce the difference in depression scores between those with and without arthritis. Persons with arthritis respond to items on the CES-D, PHQ-9, and K-6 depression scales similarly to persons without arthritis, despite the inclusion of somatic items in these scales.

Chiropractic Use, Health Care Expenditures, and Health Outcomes for Rural and Nonrural Individuals With Arthritis

ObjectiveArthritis is considered the leading cause of disability among adults in the United States today and contributes substantially to the rising cost of health care. Residents of rural areas are especially affected. The purposes of this article are to describe chiropractic use by rural and nonrural individuals with arthritis and to identify differences in other health care use and health status by those using chiropractic care plus conventional care or conventional care alone. MethodsA longitudinal cohort from panel 12 (N = 12440) of the Medical Expenditure Panel Survey spanning 2007 to 2008 was selected for this study to represent changes in health care expenditures and use and outcomes throughout this period. The population was stratified by self-reported physician-diagnosed arthritis and rural status and compared across demographics, health status, and health care use and expenditures, including use of chiropractic services plus conventional care or conventional care alone. ResultsTwice as many rural people with arthritis had 1 or more visits with a doctor of chiropractic compared with nonrural persons with arthritis. More rural chiropractic users with arthritis reported their perceived health status as excellent, very good, or good compared with nonrural chiropractic users with arthritis and to rural people with arthritis who reported no chiropractic visits. Health care expenditures for other physician services were higher among rural chiropractic users with arthritis than nonrural users with arthritis. ConclusionsDifferences in chiropractic use were observed between rural and nonrural individuals with arthritis. More studies are needed to investigate these differences and the impact on health care use and expenditures and outcomes of individuals with arthritis.

Health-related quality of life predicts future health care utilization and mortality in veterans with self-reported physician-diagnosed arthritis: The veterans arthritis quality of life study

To investigate whether health-related quality of life (HRQOL) measures predict health care utilization and mortality in a cohort of veterans with self-reported physician-diagnosed arthritis. A cohort of veterans from the Upper Midwest Veterans Integrated Service Network (VISN) was mailed a self-administered questionnaire that was composed of the SF-36V (modified from SF-36 for use in veterans) and questions regarding demographics, current smoking status, limitation of activities of daily living (ADLs), and preexisting physician-diagnosed medical conditions, including arthritis. Within subjects reporting physician-diagnosed arthritis, we analyzed the associations between the SF-36V component summary scales (physical and mental component summary, PCS and MCS, respectively) and the occurrence of any hospitalization, number of hospitalizations, number of outpatient visits, and mortality, for the year after survey administration, using multivariable regression analyses. Of 34,440 survey responders who answered a question regarding arthritis, 18,464 (58%) subjects reported physician-diagnosed arthritis. Arthritic patients in the lowest tertile of PCS scores had significantly higher odds of any hospitalization (Odds ratio (OR) 1.49, 95% confidence interval (CI) [1.25-1.76]) and mortality (OR 1.69, 95% CI [1.18-2.42]), and a significantly higher number of hospitalizations/year (Rate ratio (RR) 1.09, 95% CI [1.05-1.13]) and outpatient visits/year (RR 1.07, 95% CI [1.03-1.11]). Arthritic patients in the lowest tertile of MCS scores had significantly higher odds of any hospitalization (OR 1.20, 95% CI [1.02-1.41]), mortality (OR 2.14, 95% CI [1.56-2.94]), and a significantly higher number of hospitalizations/year (RR 1.05, 95% CI [1.02-1.09]) and outpatient visits/year (RR 1.07, 95% CI [1.03-1.11]). HRQOL, as assessed by the SF-36V, predicts future inpatient and outpatient health care utilization and mortality in veterans with self-report of physician-diagnosed arthritis.

Positive affect and disability among older Mexican Americans with arthritis.

To examine the relationship between positive affect and subsequent functional disability in older Mexican Americans with self-reported physician-diagnosed arthritis. We conducted a 2-year prospective cohort study using a population-based sample of 1,084 noninstitutionalized Mexican American subjects aged > or =65 years residing in 5 southwestern states. Measures included self-reported diagnoses of various medical conditions, functional ability, body mass index, and ratings of positive and negative affect. For 937 subjects with arthritis who reported no limitations in activities of daily living (ADLs) at baseline, 697 remained ADL independent, 84 became ADL dependent, 41 died, and 115 were lost to followup 2 years later. There was a significant association between high positive affect (score = 12) and reduced risk of ADL disability 2 years later, controlling for baseline sociodemographic variables, medical conditions, and negative affect (odds ratio 0.46, 95% confidence interval 0.22-0.94). There was an interaction effect between positive affect and sex, with positive affect having a larger effect in reducing risk of ADL dependence in men than in women. High positive affect was associated with lower incidence of ADL disability in older Mexican Americans with self-reported physician-diagnosed arthritis. The strength of the positive affect is stronger in men than in women.

The prevalence of arthritis and activity limitation and their predictors in Missouri.

Arthritis and other rheumatic conditions comprise the leading cause of disability in the United States. In 1990, an estimated 16.7% of Missourians had arthritis. By 2020, an estimated 20% of Missourians will have this condition. We examined Missouri's prevalence of self-reported physician-diagnosed arthritis, chronic joint symptoms, and activity limitation due to joint symptoms and their associations with selected predictors (i.e., socio-demographic, access to health care, risk factor, and comorbidity indicators) from Missouri's 1996 Behavioral Risk Factor Surveillance System. We conducted logistic regression analysis to generate Odds Ratios and 95% Confidence Intervals of arthritis and activity limitation across levels of predictors. Analysis indicates arthritis is under-diagnosed in younger individuals and that arthritis and activity limitation due to joint symptoms are significant contributors to functional limitation, enhancing dependency while decreasing the quality of life. As the population ages, arthritis, chronic joint symptoms, and activity limitation will become a larger public health problem.

Prevalence of arthritis in older Mexican Americans.

This study examines the prevalence of self-reported physician-diagnosed arthritis and arthritis symptoms and their relationship to functional limitations in Mexican American elderly. We conducted a cross-sectional study using a probability sample of 2,873 non-institutionalized Mexican American men and women aged 65 or older, residing in the southwestern United States. Measures included self-reported physician-diagnosed arthritis, morning pain or stiffness, pain when standing, global health rating, activities of daily living (ADL), instrumental activities of daily living (IADL), depressive symptoms, presence of chronic diseases (diabetes mellitus, hypertension, heart attack, stroke), and body mass index. The Mantel-Haenszel chi-square statistic was used to test differences by arthritis status, and a logistic regression model was used to predict the odds of having arthritis. The overall prevalence of self-reported physician-diagnosed arthritis in the sample was 40.8 percent, 50.0 percent among women and 28.8 percent among men (P < 0.001). Morning pain or stiffness was reported by 37.7 percent of respondents and pain when standing or walking by 31.9 percent. All comorbid conditions, and both IADL and ADL limitations, were more prevalent in those with arthritis than in those without arthritis. Female sex and several medical conditions were independently associated with self-reported arthritis. Self-reported physician-diagnosed arthritis is common among older Mexican Americans. Functional limitation and disability are more prevalent among subjects with arthritis than among those without arthritis.

Determinants of shoulder and elbow flexion range: Results from the San Antonio longitudinal study of aging

Objective To gain a knowledge of factors associated with impaired upper extremity range of motion (ROM) in order to understand pathways that lead to disability. Methods Shoulder and elbow flexion range was measured in a cohort of 695 community-dwelling subjects aged 65 to 74 years. Associations between subjects' shoulder and elbow flexion ranges and their demographic and anthropometric characteristics, as well as the presence of diabetes mellitus or self-reported physician-diagnosed arthritis, were examined using multivariate regression models. The relationship between shoulder or elbow flexion range and subjects' functional reach was examined to explore the functional significance of ROM in these joints. Results The flexion range for the 4 joints studied was at least 120° in nearly all subjects (≥99% of the subjects for each of the 4 joints). Multivariate models revealed significant associations between male sex, Mexican American ethnic background, the use of oral hypoglycemic drugs or insulin to treat diabetes mellitus, and a lower shoulder flexion range. A lower elbow flexion range was associated with male sex, increasing body mass index, and the use of oral hypoglycemic drugs or insulin. A higher shoulder or elbow flexion range was associated with a lower likelihood of having a short functional reach. Conclusions The great majority of community-dwelling elderly have a flexion range of shoulder and elbow joints that can be considered functional. Diabetes mellitus and obesity are two potentially treatable factors associated with reduced flexion range of these two functionally important joints.

Estrogen Replacement Therapy and Incidence of Self-Reported Physician-Diagnosed Arthritis

Background.This longitudinal study examined the association between use of estrogen replacement therapy and incidence of self-reported, physician-diagnosed arthritis.Methods.Data of 2,416 postmenopausal women who participated in the National Health and Nutrition Examination Survey Epidemiological Follow-Up Study were used in this study. Women, free of self-reported arthritis at entry into study and for 3 years thereafter, were questioned about use of estrogen and physician-diagnosed arthritis at each of the follow-up waves of study. Proportional hazard regression models were used for the analysis.Results.Use of ERT was found to be associated with higher risk of incident arthritis, after adjusting for potential confounders (RR = 1.61, CI 1.37–1.89). When ever use of ERT was replaced by duration of use in the regression model, ERT users for a year or less significantly increased their risk of incident arthritis (RR = 1.37, CI 1.07–1.74). The risk increased by 30 and 96% with hormone use for 1 to 4 and 4 to 10 years, respectively, and by 104% with hormone use for 10 or more years.Conclusion.Results suggest that users of ERT were at higher risk of developing arthritis and the longer the use of the hormone, the higher the risk.

Body mass index, weight change, and incidence of self-reported physician-diagnosed arthritis among women.

This study examined the relationship between body mass index (BMI), weight change, and arthritis in women. Data were taken from the 1982-1984 National Health and Nutrition Examination Survey Epidemiologic Follow-Up Study of 3617 women, aged 25 to 74 years. Women with a BMI greater than 32 at initial interview were at significantly higher risk of developing arthritis than women with a BMI of 19 to 21.9. Compared with stable-weight women with a BMI of less than 25, women who were obese at initial interview (BMI > 29) and who subsequently maintained their weight or gained more than 10% of their body weight were at significantly higher risk of developing arthritis. Attaining and maintaining a healthy weight may reduce the risk of developing arthritis.
