Carbohydrate intake and hypertriglyceridemia waist phenotype among Lenjan female teachers

There is conflicting evidence on the influence of carbohydrate intake and risk of hypertriglyceridemic waist (HW) phenotype. The aim of the present study was to determine the association between dietary carbohydrate intake and the prevalence of hypertriglyceridemic waist phenotype. This cross-sectional study was conducted on 442 Iranian female teachers in the age range of 20–60 years old. Validated dish based semi-quantitative food frequency questionnaire (DFQ) was used to determine usual dietary intakes. HW phenotype was defined as serum triglyceride concentrations ≥150mg/dl and concurrent waist circumference≥88 cm. No significant statistical differences were found in the age, waist circumference, physical activity levels as well as current estrogen use and prevalence of obesity across quintiles of carbohydrate intake. Participants in the highest quintile of carbohydrate intake had higher intakes of energy, fat, whole grains, refined grains, fruits, vegetables and dietary fiber compared with those in the lowest quintile. No significant difference was found in protein intake across quintiles. The prevalence of HW in the highest quintile of carbohydrate intake compared with the lowest quintile were 24.4% and 15.9%, respectively (P-value = 0.60). Carbohydrate intake had significant association with hypertriglyceridemic waist phenotype among a group of Iranian adult women. More longitudinal studies are needed.
