Abstract


Background: This study was conducted to determine the effectiveness of nutritional interventions on some non-communicable disease risk factors among Tehran's urban population.


Methods: In the TLGS, a sub-sample of 1474 subjects aged 3 years and over, was selected for dietary assessment; nutritional interventions were implemented for cases. After a 3.8 year follow up, data were collected for 578 subjects who participated in the second phase of the study. Subjects were divided into controls (356 subjects) with no intervention and cases (222 subjects) with interventions. Mean BMI, energy intake, macronutrients, fiber, micronutrients, serum lipids, FBS, systolic and diastolic blood pressure were measured and compared using paired t-test. ANCOVA used to compare these means after controlling for age, sex, and baseline variables.


Result: Adjusted for age, sex and baseline variable, FBS ( 90±17 vs. 92±14 mg/dl, p<0.001), TC (214±122 vs 232±14 mg/dl, p<0.05) and  cholesterol intake (214 vs. 232 mg/day, p<0.05) were significantly lower in the  intervention vs the control group.


Conclusion: The present study shows decreased FBS, total serum cholesterol, and daily cholesterol intake after nutritional interventions. Specific education and intervention measures with respect to cultural and socioeconomic factors may modify dietary patterns and are effective in primary prevention of non-communicable diseases.
