Pain as a predictor of frailty over time among older Mexican Americans.

ABSTRACT: The objective of this study was to examine pain as a predictor of frailty over 18 years of follow-up among older Mexican Americans who were nonfrail at baseline. Data were from a prospective cohort study of 1545 community-dwelling Mexican Americans aged ?67 years from the Hispanic Established Populations for the Epidemiological Study of the Elderly (1995/1996-2012/2013). Frailty was defined as meeting 2 or more of the following: unintentional weight loss of >10 pounds, weakness, self-reported exhaustion, and slowness. The independent predictor was self-reported pain. Covariates included age, sex, marital status, education, comorbid conditions, body mass index, Mini-Mental State Examination, depressive symptoms, and limitation in activities of daily livings. General equation estimation was performed to estimate the odds ratio of frailty as a function of pain. A total of 538 participants (34.8%) reported pain at baseline. The prevalence of frailty among those with pain ranged from 24.4% in wave 3 to 41% in wave 8. The odds ratio of becoming frail over time as a function of pain was 1.71; 95% confidence interval: 1.41 to 2.09 after controlling for all covariates. Older age, hip fracture, high depressive symptoms, and activities of daily living disability were also associated with higher odds of becoming frail over time. Female participants and those with higher levels of education and high Mini-Mental State Examination scores were less at risk. In conclusion, pain was a significantly predictor of frailty. Early assessment and better management of pain may prevent early onset of frailty in older Mexican Americans.

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.

Project description:IntroductionMultimorbidity, the co-occurrence of two or more chronic conditions, is common among older adults and is associated with decreased quality of life, greater disability, and increased mortality. Yet, the association of multimorbidity with pain, another significant contributor to decreased quality of life, has not been widely studied. This is especially understudied among very old (aged ≥ 80) Mexican Americans, a fast-growing segment of the United States (US) population.ObjectiveTo assess the association of multimorbidity with pain in very old Mexican Americans, over six years of follow-up.MethodsWe used data from Waves 7 (2010/2011) to 9 (2015/2016) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly, a longitudinal study of older Mexican Americans residing in the Southwestern US. Multimorbidity was defined as reporting two or more chronic health conditions. Pain was defined as (1) pain on weight-bearing, (2) pain in back, hips, knees, ankles/feet, legs, entire body, or two or more locations, and (3) pain that limits daily activities. We use generalized estimation equations to estimate the odds ratio of pain as a function of multimorbidity over 6 years.ResultsAt baseline (n = 841), 77.3% of participants had multimorbidity. Those with multimorbidity had greater odds [2.27, 95% confidence interval (CI): 1.74, 2.95] of reporting pain on weight-bearing over time, compared to those without multimorbidity. Also, those with multimorbidity had 2.12 times the odds of reporting pain that limited their daily activities (95% CI: 1.61, 2.78) compared to those without multimorbidity. Lastly, those with multimorbidity had higher odds of reporting pain in their back, knee, ankles/feet, legs, hips, entire body, or two or more locations, compared to those without multimorbidity.ConclusionsThose with multimorbidity consistently had higher odds of all types of pain, highlighting the need for early management of pain among those with multiple chronic conditions and complex health needs. This is especially important among very old Mexican Americans, who have a high burden of chronic health conditions.

Project description:BACKGROUND:Little is known regarding the impact of transitions in frailty on healthcare use and payment in older Mexican Americans. We address this gap in knowledge by investigating the effect of early transitions in physical frailty on the use of healthcare services and Medicare payments involving older Mexican Americans. METHODS:Longitudinal analyses were conducted using the Hispanic Established Populations for the Epidemiological Study of the Elderly (Hispanic-EPESE) survey data from five Southwest states linked to the Medicare claims files from the Centers for Medicare and Medicaid Services. Seven hundred and eighty-eight community-dwelling Mexican Americans 72?years and older in 2000/01 were studied. We used a modified Frailty Phenotype (unintentional weight loss, weakness, self-reported exhaustion and slow walking speed) to classify frailty status (non-frail, pre-frail or frail). Each participant was placed into one of 5 frailty transition groups: 1) remain non-frail, 2) remain pre-frail, 3) remain frail, 4) improve (pre-frail to non-frail, frail to non-frail, frail to pre-frail) and 5) worse (non-frail to pre-frail, non-frail to frail, pre-frail to frail). The outcomes for the one-year follow-up period (2000-2001) were: (a) healthcare use (hospitalization, emergency room [ER] admission and physician visit); and (b) Medicare payments (total payment and outpatient payment). RESULTS:Mean age was 78.8 (SD?=?5.1) years and 60.3% were female in 1998/99. Males who remained pre-frail (Odds Ratio [OR]?=?3.49, 1.13-10.8, remained frail OR?=?6.92, 1.61-29.7) and transitioned to worse frail status (OR?=?4.49, 1.74-11.6) had significantly higher hospitalization risk compared to individuals who remained non-frail. Males in the 'worsened' groups, and females in the 'improved' groups, had significantly higher Medicare payments than individuals who remained non-frail (Cost Ratio [CR]?=?2.00, 1.30-3.09; CR?=?1.53, 1.12-2.09, respectively]. CONCLUSIONS:Healthcare use and Medicare payments differed by frailty transition status. The differences varied by sex. Research is necessary to elucidate the relationship between frailty transitions and outcomes, sex difference and Medicare payment for older Mexican Americans living in the community.
