Association between the index of nutritional quality and lipid profile in adult women

Abstract

Background: Dyslipidaemia is a group of abnormalities that predispose people to heart disease. The index of nutritional quality (INQ) is a tool for qualitative and quantitative nutritional assessment, which has special significance in assessing clinical nutritional problems. The objective of this study was to determine the association between the INQ and lipid profile in adult women.Methods: This was a cross-sectional study on 360 healthy women referring to the nutrition clinic of Shohadaye Tajrish hospital, Tehran, Iran. Calorie and nutrient intake were assessed using a validated food frequency questionnaire. The amount of physical activity was estimated using a validated International Physical Activity Questionnaire. To measure serum lipid levels, 5 ml of venous blood samples was taken from the participants. Results:The results showed a negative association between total cholesterol and the INQ of niacin (B = −0.110, p = .02) and between high-density lipoprotein cholesterol with the INQ of biotin (B = −0.119, p = .01). Also, a positive association was found between triglyceride and the INQ of B6 (B = 0.096, p = .04). The results remained
