Determination of the relationship between healthy feed index and diet quality index which are determined in different two days in adolescents

İrem AYHAN TURAL, Determination of the Association Between Dietary Intakes Determined in Two Non-Consecutive Days, Healthy Eating Index and Diet Quality Index Among Adolescents, Hasan Kalyoncu University Institute of Health Sciences Nutrition and Dietetics MSc Thesis, Gaziantep, 2018. The aim of this study is to determine the association between dietary intakes determined in two non-consecutive days, and Healthy Eating Index and Diet Quality Index. In this study diet quality among adolescents were evaluated using Healthy Eating Indeks (HEI-2010), Diet Quality Indeks (DQI-I) and Medietarranean Diet Quality (KIDMED). The study was conducted on a total of 200 adolescents (boys: 62, 31.0%; girls: 138, 69.0%), aged 15 to 18 years, accepted to participate the study in Mehmet Sanlı Vocational and Technical Anatolian High School in Kilis. Using a questionnaire, general characteristics, nutritional habits, 24 hour dietary intake recall, food consumption frequency, physical activity status, anthropometric measurements and body composition were determined. Percentages of obesity among boys and girls were 4.8% and 8.7% and overweight were 8.1% and 15.9%. HEI-2010, DQI and KIDMED scores were calculated depending on 24-hour dietary recall (24-hDR) on two randomly-selected non-consecutive days (a 14-day interval). None of the adolescents had a good dietary quality (HEI score: ≥80). Mean HEI-2010 score of 1st (baseline) and 14th days was 46.2 for boys and 48.7 for girls and out of total 49.5% had diet quality determined as poor (<50 points). Total fruit, whole fruit and total vegetable scores were found statistically significant (p <0.05, p <0.01) according to gender and higher in girls. Mean DQI-I score of 1st and 14th days was 50.7 for boys and 45.5 points for girls out of 100. Total vegetables, total grains, fibre, protein, total fat, saturated fat, fatty acids and total DQI were found statistically significant (p <0.01, p <0.05) according to gender. Protein score was higher, total vegetable, fiber, total fat, saturated fat, fatty acids and total DQI-I scores were lower in girls than boys. Mean KIDMED score of adolescents was found as 4.1±2.33 (boys: 4.4±2.43, girls: 3.9±2.27) points. It has been determined that the adolescents' diet quality is not good, so nutrition intervention and promotion programmes should be implemented.
