Introduction Demand for diabetes and hypertension services is expected to rise rapidly in the coming years given that Mexico has a high rate of obesity and recently created Popular Health Insurance (PHI), a program to extend health insurance to the 57% of the population without coverage. This paper examines the extent to which the service supply (i.e. number of physicians, number of nurses, number of beds etc.) predicts utilization of diabetic and hypertensive health care services amongst obese Mexican adults, who qualify for PHI.
Data and Methods To identify the prevalence and distribution of diabetes and hypertension, the Mexican National Health Survey (2000) with a sample of 47,674 adults was used. Supply-side data was obtained from the Mexican National Registry of Health Infrastructure (2000). Each data set is representative at the national and state level. Multivariate analysis was used to estimate the independent effect of supply-side services on health service utilization.
Results While there is little variation in the prevalence of diabetes and hypertension amongst obese adults across the Mexican states, service availability varies significantly. Within each geographical subgroup, crude rates of hospital beds, doctors, operating rooms, and nurses rise with income. After adjusting for geography, income, and gender the availability of supply side services is associated with utilization of services.
Conclusions Supply side infrastructure is a significant predictor of hypertensive and diabetic service use among the adult obese population in Mexico. However, utilization of services cannot be explained by the service supply alone; geography and income are also important predictors.
