Longitudinal and reciprocal associations between financial strain, home characteristics and mobility in the National Health and Aging Trends Study.

BACKGROUND: Older adults need homes that suit their physical capacity. Financial strain may limit home repairs and modifications and prompt relocations; repairing, relocating or modifying may increase financial strain. Likewise, reciprocal relationships may exist between financial strain and home characteristics and mobility; financial strain and home characteristics may influence mobility and mobility declines may increase financial strain, limit home repairs and modifications and prompt relocations. We test cross-lagged associations between financial strain, home disorder, relocation, home modifications and mobility. METHODS: In the National Health and Aging Trends Study, ability to complete a walking test, speed among those able to complete, financial strain, home disorder, relocating and modifying the home were recorded annually for 3 years (2012-2014). Structural equation models separately examined ability to walk and walking speed among those able, accounting for sociodemographic characteristics, social support, health prior health characteristics and autoregressive effects. Sampling weights accounted for the complex survey design and non-response over time. RESULTS: In both models (n = 3234 and n = 2467), financial strain predicted greater home disorder and vice versa, but cross-lagged associations were not found with relocating and modifications. Greater home disorder predicted lower odds of ability to walk and slower speed among those able. Financial strain and home modifications predicted lower odds of ability to walk. Also, faster walking speed predicted lower odds of subsequent financial strain and lower subsequent home disorder scores and ability to walk predicted less subsequent home disorder and lower odds of relocating. CONCLUSIONS: Home disorder links financial strain with reduced mobility in a national sample of U.S. older adults. Cross-lagged associations between financial strain and home disorder and between home disorder and mobility suggest reciprocal effects that may accumulate over time. Also, financial strain, reduced mobility, relocations and modifications predicted greater home disorder. Together, these results highlight home disorder as a social determinant of mobility for older adults. Greater attention should be given to repairing and modifying home environments and supporting stable housing for older adults with financial strain.

Community Characteristics are Associated with Blood Pressure Levels in a Racially Integrated Community.

Community problems have been associated with higher, and community resources and social cohesion with lower, blood pressure. However, prior studies have not accounted for potential confounding by residential racial segregation. This study tested associations between community characteristics and blood pressure levels and prevalent hypertension in a racially integrated community. The Exploring Health Disparities in Integrated Communities Study measured blood pressure in residents of two contiguous racially integrated and low-income US Census Tracts. Community characteristics included a standardized community problem score and binary indicators for community social cohesion, having a community leader available, and having at least one community resource observed on the participant's block. In adjusted models, greater community problems and proximity to resources were associated with lower systolic (ß = -2.020, p = 0.028; ß = -4.132, p = 0.010) and diastolic (ß = -1.261, p = 0.038; ß = -2.290, 0.031) blood pressure, respectively, among whites (n = 548). Social cohesion was associated with higher systolic (ß = 4.905, p = 0.009) and diastolic blood pressure (ß = 3.379, p = 0.008) among African Americans (n = 777). In one racially integrated low-income community, community characteristics were associated with blood pressure levels, and associations differed by race. Directions of associations for two findings differed from prior studies; greater community problem was associated with lower blood pressure in whites and community social cohesion was associated with higher blood pressure in African Americans. These findings may be due to exposure to adverse environmental conditions and hypertensive risk factors in this low-income community.
