The Relationship between Diet Group and Composition of Blood Lipids in Adolescents

Background and Suitable diets during adolescence are effective in providing nutritional needs, and allowing physical and mental growth in adolescents, and in preventing chronic diseases in adulthood. Some studies suggest a relationship between nutritional status and composition of blood lipids. This study was designed to investigate the association between intake of different food groups and composition of blood lipids in adolescents. In this descriptive-analytic study, 312 adolescents aged 10-18 years old were selected using random cluster sampling in 2011. Nutritional and biochemical information was collected for all participants and analyzed using SPSS V. 16. The mean age of the subjects was 15.07±2.42 years and there were 51% female and 49% male. Significant correlation was found between intake of bread and cereals (P=0.001), milk and dairy products (P=0.047), and vegetable groups (P=0.021) with HDL cholesterol levels in adolescents. According to this study nutritional status of the studied adolescents should be improved. Paying more attention to quality and variety of dietary intake could have important effects on modifying the risk factors for various diseases in this age group.
