New Publication in The Journals of Gerontology: Social Sciences

Latham, K. (2014). Racial and educational disparities in mobility limitation among older women: What is the role of modifiable risk factors? The Journals of Gerontology, Series B: Social Science. Advance online publication. doi: 10.1093/geronb/gbu028

My recent publication examines whether modifiable risk factors such as smoking status, participation in vigorous physical activity, or body mass index mediates or moderates racial and educational disparities in mobility limitation (i.e., difficulty walking or climbing stairs) among older women. Body mass index was a significant partial mediator for race and mobility limitation–suggesting that higher levels of body mass index among older Black women,  relative to older White women, contributes to excess mobility impairment. Another interesting finding highlights racial variation in the effect of modifiable risk factors on mobility limitation; the benefit of vigorous physical activity for preventing mobility limitation varied by race. Physical activity among older Black women was not as advantageous for preventing mobility limitation compared with older White women.
