Obesity and health conditions in elderly Mexican Americans: the Hispanic EPESE. Established Population for Epidemiologic Studies of the Elderly.

The objective of this analysis was to determine the prevalence of obesity and its association with selected medical conditions in a non-institutionalized elderly Mexican-American population. Data employed are from a representative sample of 3050 elderly Mexican Americans from the five Southwestern states: Texas, California, Colorado, New Mexico, and Arizona. Complete Body Mass Index (BMI) data were available for 2769 individuals. The in-home survey obtained socio-demographic data, anthropometric measurements, including height and weight, blood pressure readings, self-reported health conditions and depressive symptomatology. It was found that 23% of men and 35% of women were obese (BMI > or =30 kg/m2). Using a weighted logistic regression model, a BMI of > or =26 kg/m2 was associated with a significantly higher risk of diabetes; a BMI of > or =30 kg/m2 was significantly associated with arthritis and measured hypertension and a BMI<22 kg/m2 was associated with a higher likelihood of self-reported cancer. In addition, the prevalence of obesity was found to be much higher in this elderly Mexican-American population than in the general population.
