Abstract: BACKGROUND:Few studies have shown the protective effects of Mediterranean Dietary Pattern (MDP) in psychological disorders. OBJECTIVE:This cross-sectional study was designed to determine the association between adherence to MDP and depression, anxiety and stress among female adolescents aged 16.20±0.97 in Tehran, Iran. METHODS:Data from 263 participants were analyzed. Adherence to MDP was determined using Mediterranean-Style Dietary Pattern Score (MSDPS). Depression, anxiety and stress scores were characterized by DASS-21 (Depression Anxiety Stress Score-21 items) questionnaire. RESULTS:Multivariable logistic regression was used to determine the prevalence of depression, anxiety, and stress across quintiles of MSDPS. After adjustment for age, the odds ratio (OR) for depression in the highest quintile of MSDPS was 0.44 (95% confidence interval [95%CI], 0.19–0.95), (P for trend = 0.009) compared to the lowest quintile. After additional adjustment for BMI, energy intake, physical activity, ethnicity, parents education level and total family income, subjects in the highest quintile had a 59% lower prevalence of depression compared to those in the lowest quintile of MSDPS (OR = 0.41;95% CI, 0.17–0.97), (P for trend = 0.010). However, the MSDPS was not significantly associated with the presence of anxiety and stress. CONCLUSION:Adherence to MDP is associated with a reduced presence of depressive symptoms in female adolescents.
