ASSOCIATION OF LOW -CARBOHYDRATE DIET SCORE WITH OVERWEIGHT, OBESITY AND CARDIOVASCULAR RISK FACTORS: A CROSS-SECTIONAL STUDY AMONG IRANIAN WOMEN

Background and Aim: To determine the association of low-carbohydrate-diet score and overweight, obesity and cardiovascular risk factors among 209 Iranian women.Methods: This is a cross-sectional study was conducted on 209 healthy adult women. Dietary intake was evaluated by a validated food frequency questionnaire. Participants were divided into decile of macronutrients intake. Women in the lowest decile of carbohydrate intake received a score of 9 and women in the highest decile received a score of 0. For protein and fat, the same scoring was used but the order was reversed. Then, macronutrients scores were summed to create the low-carbohydrate-diet score which ranged from 0 to 27. Anthropometric indices, blood pressure, fasting blood glucose and lipid profiles were measured. Continuous and qualitative variables were compared among low-carbohydrate-diet score by one-way ANOVA and Chi-square test, respectively. Logistic regression was used to determine the association of low-carbohydrate-diet score and all cardiovascular risk factors Results: The odds ratio for overweight, obesity and cardiovascular risk factors, were not significant among the tertiles of this score. After controlling for energy intake, women at the highest tertile of low-carbohydrate-diet score had odds ratio of 0.93, 0.39, 0.57, 0.65, 0.67, 1.14, 0.88, 1.67, 0.95, and 0.53 for overweight, obesity, abdominal obesity, high fasting blood glucose, high triglyceride, high systolic and diastolic blood pressure, low HDL cholesterol, high total cholesterol and high LDL-cholesterol, respectively.Conclusion: Diets with lower carbohydrate and higher content of protein and fat were not associated with overweight, obesity and cardiovascular risk factors.
