Polyakova M, et al. - Via a cross-sectional association study of 6,363,097 Medicare beneficiaries who were aged 66 to 100 years and had a history of low-income support under Medicare Part D, researchers assessed the correlation between the prevalence of chronic conditions among low-income, elderly adults and the economic affluence of a local area. Of 48 chronic conditions, the crude prevalence varied from 72.5 per 100 to 0.6 per 100 for hypertension and for posttraumatic stress disorder, respectively. The predominance of these 48 chronic conditions was highly spatially related to one another. In more affluent commuting zones, composite condition predominance was on average substantially lower. In conclusion, low-income, elderly people living in more affluent areas of the country are more salubrious, and in regions with poor health in the low-income, the elderly population tend to have a great predominance of most chronic maladies.
