Abstract

OBJECTIVE: The present study evaluated the association of two measures of diet quality with BMI and waist circumference (WC), overall and by education level, among Mexican men and women. DESIGN: We constructed two a priori indices of diet quality, the Mexican Diet Quality Index (MxDQI) and the Mexican Alternate Healthy Eating Index (MxAHEI), which we examined relative to BMI and WC. We computed sex-specific multivariable linear regression models for the total sample and by education level.
SETTING: Mexico.
PARTICIPANTS: Mexican men (n 954) and women (n 1356) participating in the Mexican National Health and Nutrition Survey 2012.
RESULTS: Total dietary scores were not associated with BMI in men and women, but total MxDQI was inversely associated with WC in men (-0.10, 95 % CI -0.20, -0.004 cm). We also found that some results differed by education level in men. For men with the lowest education level, a one-unit increase in total MxDQI and MxAHEI score was associated with a mean reduction in BMI of 0.11 (95 % CI -0.18, 0.04) and 0.18 (95 % CI -0.25, -0.10) kg/m2, respectively. Likewise, a one-unit increase in total MxDQI and MxAHEI score was associated with a mean change in WC of -0.30 (95 % CI -0.49, -0.11) and -0.53 (95 % CI -0.75, -0.30) cm, respectively, in men with the lowest level of education. In women, the association of diet quality scores with BMI and WC was not different by education level.
CONCLUSIONS: Our findings suggest that a higher diet quality in men with low but not high education is associated with lower BMI and WC.
