Key result
Higher age, higher BMI, lower vegetable and fruit consumption, and higher fast food intake were significant predictors of high blood pressure, with the combined lifestyle model explaining 32.1% of the variance.
Why the study?
To evaluate dietary patterns and lifestyle-associated factors in predicting hypertension among overweight and obese pediatric populations.

Lower vegetable and fruit consumption, higher fast food intake, older age, and higher BMI are potent predictors of high blood pressure in overweight and obese Iranian children and adolescents.
Objective: The aim of this study is the evaluate of dietary pattern and life style associated factors in predicting hypertension among overweight and obese pediatrics. In the current cross-sectional study, 425 overweight and obese children and adolescents aged 6 to 18 years were enrolled. The predictors of blood pressure were included in the scoring algorithm. Results: The results showed that SBP and DBP had directly correlation with age (p<0.001, p<0.001) and BMI (p<0.005, p<0.007) respectively. Moreover, DBP was in correlation with fruit consumption of less than 2 serving per day versus never consumption (p=0.014, B= 0.444), fruit consumption of more than 2 serving per day versus never consumption (p=0.014, B= 0.480), and vegetable consumption less than 3 serving per day versus never consumption (p=0.045, B= -0.374). Also, results showed that DBP had significant correlation with fast foods /junk foods consumption of 1-2 items per week versus almost every day consumption (p= 0.047, B=-0.177). This final model could predict 32.1% of hypertension by SBP and DBP (R2 =0.321). According to our findings, consumption of lower vegetables and fruits, higher amounts of fast foods, higher age and BMI could be potent predictors of high blood pressure among Iranian children and adolescents.

Taghizadeh et al. (2020) conducted a cross-sectional in Overweight and obesity (predictors of hypertension) (n=425). Dietary and lifestyle factors (including fast food, fruit, and vegetable consumption) vs. Reference dietary and lifestyle patterns was evaluated on Systolic and diastolic blood pressure variance explained by the final hierarchical regression model (R2 = 0.321). Higher age, higher BMI, lower vegetable and fruit consumption, and higher fast food intake were significant predictors of high blood pressure, with the combined lifestyle model explaining 32.1% of the variance.
