Summary

Obesity is more common in Mexican Americans than other Hispanic groups, but it doesn't fully explain their higher diabetes rates. Cardiovascular risk factors were similar across groups, with higher values in diabetics.

Area of Science:

  • Public Health
  • Epidemiology
  • Nutritional Science

Background:

  • Obesity prevalence is higher in Hispanic Americans compared to White Americans.
  • Mexican Americans exhibit a greater prevalence of obesity than Cuban Americans or Puerto Ricans.
  • Diabetes prevalence increases with obesity levels (body mass index).

Purpose of the Study:

  • To investigate the relationship between obesity and diabetes prevalence in Mexican Americans.
  • To examine cardiovascular disease risk factors in Mexican Americans with and without diabetes.
  • To compare nutrient intake and dietary atherogenicity between rural and urban Mexican American populations.

Main Methods:

  • Cross-sectional study comparing obesity and diabetes prevalence across Hispanic subgroups.
  • Analysis of cardiovascular disease risk factors including high-density lipoprotein cholesterol subfractions and systolic blood pressure.
  • Nutrient intake assessment using dietary surveys and calculation of the Keys score.

Main Results:

  • High obesity prevalence in Mexican Americans does not entirely account for their elevated diabetes rates.
  • Cardiovascular disease risk factor associations were similar between Mexican Americans and other U.S. populations.
  • Individuals with diabetes showed higher values for selected cardiovascular risk factors.
  • Rural Mexican Americans consumed more calories and had a more atherogenic diet (higher Keys score) than urban counterparts.

Conclusions:

  • Factors beyond obesity contribute to the higher diabetes prevalence in Mexican Americans.
  • Dietary patterns, particularly calorie intake and atherogenicity, may play a role in cardiovascular health disparities.
  • Further research is needed to elucidate the complex interplay of obesity, diet, and diabetes in this population.
