The Hispanic Paradox and older adults' disabilities: is there a healthy migrant effect?

Aging and place--neighborhoods and health in a world growing older

The articles in this special issue make it clear that there are interesting and policy-relevant research to identify place-based strategies to improve health and reduce health disparities among older adults. The articles also reveal important areas of future research and policy innovation that are needed related to place and aging.

Functional disability in late-middle-aged and older adults admitted to a safety-net hospital

OBJECTIVES

To determine the prevalence of preadmission functional disability in late-middle-aged and older safety-net inpatients and to identify characteristics associated with functional disability by age.

DESIGN

Cross-sectional analysis.

SETTING

Safety-net hospital in San Francisco, California.

PARTICIPANTS

English-, Spanish-, and Chinese-speaking community-dwelling individuals aged 55 and older admitted to a safety-net hospital with anticipated return to the community (N = 699).

MEASUREMENTS

At hospital admission, participants reported their need for help performing five activities of daily living (ADLs) and seven instrumental activities of daily living (IADLs) 2 weeks before admission. ADL disability was defined as needing help performing one or more ADLs and IADL disability as needing help performing two or more IADLs. Participant characteristics were assessed, including sociodemographic characteristics, health status, health-related behaviors, and health-seeking behaviors.

RESULTS

Overall, 28.3% of participants reported that they had an ADL disability 2 weeks before admission, and 40.4% reported an IADL disability. The prevalence of preadmission ADL disability was 28.9% of those aged 55 to 59, 20.7% of those aged 60 to 69, and 41.2% of those aged 70 and older (P < .001). The prevalence of IADL disability had a similar distribution. The characteristics associated with functional disability differed according to age; in participants aged 55 to 59, African Americans had a higher odds of ADL and IADL disability, whereas in participants aged 60 to 69 and aged 70 and older, inadequate health literacy was associated with functional disability.

CONCLUSION

Preadmission functional disability is common in individuals aged 55 and older admitted to a safety-net hospital. Late-middle-aged individuals admitted to safety-net hospitals may benefit from models of acute care currently used for older adults that prevent adverse outcomes associated with functional disability.

Neighborhood context and the Hispanic health paradox: differential effects of immigrant density on children׳s wheezing by poverty, nativity and medical history

Prior research suggests that immigrant enclaves provide respiratory health benefits for US Hispanic residents. We test if immigrant enclaves provide differential respiratory health benefits for Hispanic children in El Paso (Texas) based on individual-level factors. Results reveal that higher neighborhood immigrant density is associated with reduced odds of wheezing, but that the protective immigrant enclave effect is modified by poverty, general health status, body mass index (BMI), and caretaker nativity. Higher immigrant density is significantly more protective for poor children and those with foreign-born caretakers; conversely, it is significantly less protective for children in worse health and those with higher BMI. These findings foster a novel understanding of how immigrant enclaves may be differentially protective for Hispanic children based on individual-level factors.

Investigating social ecological contributors to diabetes within Hispanics in an underserved U.S.-Mexico border community

Hispanics bear a disproportionate burden of diabetes in the United States, yet relations of structural, socio-cultural and behavioral factors linked to diabetes are not fully understood across all of their communities. The current study examines disparities and factors associated with diabetes in adult Hispanics of Mexican-descent (N = 648) participating in a population survey of an underserved rural U.S.-Mexico border community. The overall rate of diabetes prevalence rate in the sample, based on self-report and a glucose testing, was 21%; much higher than rates reported for U.S. adults overall, for all Hispanic adults, or for Mexican American adults specifically. Acculturation markers and social determinants of health indicators were only significantly related to diabetes in models not accounting for age. Older age, greater BMI (>30), greater waist-to-hip ratio as well as lower fruit and vegetable consumption were significantly related to increased likelihood of diabetes when all structural, cultural, behavioral, and biological factors were considered. Models with sets of behavioral factors and biological factors each significantly improved explanation of diabetes relative to prior social ecological theory-guided models. The findings show a critical need for diabetes prevention efforts in this community and suggest that health promotion efforts should particularly focus on increasing fruit and vegetable consumption.
