Gender Differences in the Combined Effects of Cardiovascular Disease and Osteoarthritis on Progression to Functional Impairment in Older Mexican Americans.

ABSTRACT: Comorbidity (COM) is an important issue in aging. Cardiovascular disease (CVD) and osteoarthritis separately and together may modify the trajectories of functional decline. This analysis examines whether specific and unrelated COMs influence functional change differently and vary by gender.A cohort study of 1,789 (aged 60 years and older) Mexican Americans was followed annually for up to 10 years. We created four groups of COM (CVD alone, lower body osteoarthritis alone [OA], neither, or both). We employed mixed effects Poisson models with Instrumental Activities of Daily Living (IADL) as the outcome. We tested whether the association between COM and decline in functional status differed by gender.IADL impairments in those with CVD, OA, or both were significantly higher at baseline and increased more rapidly over time compared to those with neither condition. Compared to women with no COM, the number of IADL impairments in women with CVD alone were 1.36 times greater, with OA were 1.35 times greater, and both conditions were 1.26 times greater. Compared to men with no COM, IADL impairments in men with CVD alone were 1.15 times greater, OA alone were 1.12 times greater, and both were 1.26 times greater.Over time, the influence of COM on functional decline differs by specific combinations of COM and by gender. Aggregate COM scales obscure the biological and temporal heterogeneity in the effects of COM. Time-dependent-specific COMs better assess the development of impairment. Women experience a higher burden of functional impairment due to COM than men.

Project description:BackgroundThe association between stroke and dementia is well established. Less is known about this association in underrepresented ethnic groups. In a large ethnically diverse cohort, we examined whether history of stroke was associated with cognitive impairment, and whether this relationship differed by ethnicity (Mexican American [MA] versus non-Hispanic White).MethodsThis was a population-based cohort study conducted in Nueces County, TX, a biethnic community with a large and primarily nonimmigrant MA population. Residents aged ≥65 were recruited door-to-door or by telephone between May 2018 and December 2021. The primary exposure was history of stroke, obtained by self-report. Demographic, medical, and educational histories were also obtained. The primary outcome was the Montreal Cognitive Assessment (MoCA), a scale that evaluates multiple domains of cognitive performance. Scores were divided into 3 ordinal categories, roughly corresponding to normal cognition (MoCA 26-30), mild cognitive impairment (MoCA 20-25), or probable dementia (MoCA 0-19).ResultsOne thousand eight hundred one participants completed MoCA screening (55% female; 50% MA, 44% Non-Hispanic White, 6% other), of whom 12.4% reported history of stroke. Stroke prevalence was similar across ethnicities (X2 2.1; P=0.34). In a multivariable cumulative logit regression model for the ordinal cognition outcome, a stroke by ethnicity interaction was observed (P=0.01). Models stratified by ethnicity revealed that stroke was associated with cognitive impairment across ethnicities, but had greater impact on cognition in non-Hispanic Whites (cumulative odds ratio=3.81 [95% CI, 2.37-6.12]) than in MAs (cumulative odds ratio=1.58 [95% CI, 1.04-2.41]). Increased age and lower educational attainment were also associated with cognitive impairment, regardless of ethnicity.ConclusionsHistory of stroke was associated with increased odds of cognitive impairment after controlling for other factors in both MA and Non-Hispanic White participants. The magnitude of the impact of stroke on cognition was less in MA than in Non-Hispanic White participants.

Project description:ObjectivesDevelop and validate a modified frailty phenotype measure for older Mexican Americans participating in the Hispanic Established Populations for the Epidemiological Study of the Elderly (H-EPESE) and related studies.DesignExpert-based panel evaluation of content validity, cross-sectional analysis of construct validity, and longitudinal analysis of criterion validity for a modified version of the frailty phenotype measure.SettingFive southwestern states.ParticipantsA total of 1833 community-dwelling Mexican Americans aged 67 years or older.MeasurementsFrailty was assessed using the frailty phenotype measure (weight loss, weakness, exhaustion, slowness, and low physical activity) and a modified frailty phenotype measure (replacing "low physical activity" with "limitations in walking half a mile"). Each individual was classified as non-frail, pre-frail, or frail based on both frailty measures (original vs modified). Expert panel consensus was used to examine content validity. Spearman correlation, κ, weighted κ, and bootstrapping κ examined construct validity (n = 1833). Generalized linear mixed models, odds ratios, Cox proportional regression models, hazard ratios, and C statistics were used to analyze criterion validity (n = 1446) across four outcomes: hospitalization, physician visits, disability, and mortality from wave 3 (1998-99) through wave 8 (2012-13).ResultsThe original and modified frailty phenotype measures had a strong correlation (r = .89; P < .000) and agreement (κ = .84; 95% confidence interval [CI] = .81-.86; weighted κ = .86; 95% CI = .84-.88; bootstrap κ = .84; 95% CI = .81-.86; bootstrap-weighted κ = .86; 95% CI = .84-.88 with 1000 bootstrapping samples). Four outcome models showed similar risk predictions for both frailty measures, with the exception of physician visits for frail participants.Conclusion"Limitations in walking half a mile" can be used as a substitute criterion for "low physical activity" in assessing frailty. The modified frailty phenotype measure was comparable with the original frailty phenotype measure in H-EPESE participants over time. Our results indicate the modified frailty phenotype is a useful longitudinally frailty measure for community-dwelling older Mexican Americans. J Am Geriatr Soc 67:2393-2397, 2019.
