Sommaire de l'article
OBJECTIVE: To investigate the relationship between dietary patterns and self-perceived body shape silhouette and BMI in a sample of Mexican women.
DESIGN: A cross-sectional analysis of dietary habits from baseline data of a large cohort study (EsMaestra) conducted in 2006-2008.
SETTING: The state of Veracruz, Mexico.
SUBJECTS: Mexican teachers (n 20 330) provided information on body shape silhouette at baseline, changes in body shape silhouette and BMI, as well as information on sociodemographic variables and lifestyle.
RESULTS: The median BMI was 26·8 kg/m2; 43 % of women were overweight and 24 % were obese. The carbohydrates, sweet drinks and refined foods pattern was associated with a greater risk of having a large silhouette and a large BMI (BMI ≥ 30·0 kg/m2 v. BMI < 25·0 kg/m2; ORT1-3 = 1·86, 95 % CI 1·56, 2·22 and 1·47, 95 % CI 1·28, 1·69, respectively) with a significant trend when comparing the first and third tertiles of intake. The fruit and vegetable pattern was associated with a lower risk of having a large silhouette and a large BMI (ORT1-3 = 0·68, 95 % CI 0·57, 0·82 and ORT1-3 = 0·77, 95 % CI 0·67, 0·88, respectively) with a significant decreasing trend. Similar results were observed when change in silhouette (from 18 years of age to current silhouette) was considered.
CONCLUSIONS: High intakes of carbohydrates, sweet drinks and refined foods are related to larger silhouettes. Public health intervention improving access to healthy dietary guidelines, healthy food choice in the work place, promotion of physical activity and regulation of beverages with a high sugar content and of refined foods should be considered.
