Primary care
has a large effect on self-reported health, especially in areas where there
are large differences in income between the non-wealthy and the wealthy
(high income inequality). In 60 nationally representative US communities,
areas with moderate income inequality have a 16% higher proportion of people
reporting fair or poor health if primary care resources are low. The effect
of primary care is twice as great in the most socially deprived areas: a 33%
increase in fair or por health if primary care resources are in poor supply.
Based on data in: Shi L, Starfield B. Primary care, income
inequality, and self-rated health in the United States: a mixed-level
analysis. Int J Health Serv 2000; 30(3):541-555.
