[Factors associated with the demand for delivery care in Mexico]

Analyze the factors associated with the utilization of delivery care institutions in Mexico in order to document the functional integration of health institutions.

Based on the 2006 National Health and Nutrition Survey, information from women whose last birth was between 2000 and 2005 was used. Chi square was used to test differences between institutions used and health insurance type. A logistic regression was carried out to identify factors associated with the demand for institutions with which women were not affiliated.

Women with social security used in 62% of the cases the institution of their affiliation and 13.4% used public institutions. For uninsured women, 43.3% used public institutions and 19.0% social security institutions; 64.3% of the Seguro Popular affiliates were treated in public institutions. Variables related to access, socioeconomic status and living conditions influenced said demand.

The utilization of an institution of delivery that differed from the one with which the women were affiliated indicates the existence of a de facto functional integration between health institutions in Mexico.
