Background and Objectives: Due to high prevalence of overweight and obesity in Iran and the socio-economical burden of obesity, diagnosis of a healthy diet that can prevent weight gain is essential. This study aimed to determine the relationship between adherence to Mediterranean Style Dietary Pattern Score (MSDPS) with overweight and obesity in female adolescents aged 15-18 years in Tehran.

 Materials and Methods: In this cross-sectional study, 280 female adolescents from
high schools in Tehran were recruited by multi-stage stratified cluster sampling. General information, physical activity and food frequency questionnaires were completed. Weight, height, waist circumference (WC), and hip circumference (HP) were measured. BMI and Waist to Hip Ratio (WHR) were calculated. MSDPS was calculated. Relation of MSDPS with BMI, WC and WHR was analyzed using Bon-Ferroni.

Results: Statistical analyses were done on 280 female adolescents. The results indicated that prevalence of overweight and obesity was 13/3% and 12/5%, respectively. Mean ± standard deviation of MSDPS was 15/99 ± 5/64, and generally, it was low in this population. MSDPS was positively associated with mother's education level and energy intake (p<0/05). No relation was observed between MSDPS and overweight and obesity among the adolescents.

Conclusion: MSDPS among adolescent females in Tehran is low. There is no association between MSDPS and overweight and obesity among the participants though mother's level of education has a positive effect on compliance.
