Objectives. This study examined factors associated with gender differences in health insurance coverage and having a usual source of medical care.Methods. In-person interviews were conducted with a community sample of 695 residents of Central Harlem, New York City. Predictors of the 2 outcome variables and the interaction of key variables with gender were analyzed via logistic regression.Results. No strong patterns emerged to explain gender differentials in having insurance coverage and having a usual provider. However, women employed full time had increased odds of insurance coverage, whereas employment had no similar effect among men. Public assistance evidenced a strong relationship with insurance coverage among both men and women. Socioeconomic factors and health insurance were important independent predictors of having a usual source of health care for men but had little effect among women.Conclusions. Expanding the availability of both public insurance and affordable private coverage for men living in low-income communities is an important means of reducing gender disparities in access to health care. Public assistance is an important means of enabling access to health care for men as well as women. A common premise of health research is that gender operates as an independent influence on virtually any population-based outcome of interest. This assertion is supported in the literature, which consistently indicates that men and women differ in regard to health, access to health care, and use of health services. As a result, gender is typically viewed as a variable that must be controlled in analyses. This approach, however, does not permit explicit examination of the underlying inference that predictive models may vary by gender. As a result, our understanding of most influences on health-related outcomes is based on effects independent of gender.While many studies identify the general determinants of health insurance and a usual source of medical care, including gender, few examine how these factors differ between men and women. This is a significant gap in that most research shows that women are more likely than men to have access to both insurance coverage and a usual source of care. Understanding the interplay between gender and the distinct determinants of these indicators has important implications for policies designed to promote equal access to health care.US national surveys demonstrate that men are less likely than women to have health insurance coverage.1,2 In general, the most important determinants of insurance status are income and employment-related factors, the latter the result of the predominance of employment-based coverage in the United States.3,4 While men who work full time are more likely than women who work full time to have employment-based coverage, this trend may be a result of the tendency of married working women to decline their own coverage in favor of their husband's insurance. Indeed, single women who work full time are slightly more likely than men to be covered through the...
