Objective To investigate seasonal variations of vitamin D status at different latitudes and if these changes are accompanied by corresponding variations in certain health parameters in children living in a broad latitudinal range in Iran. Design Longitudinal study. Subjects In total, 530 apparently healthy children aged 5–18 years were randomly selected from six regions of Iran with a latitudinal gradient from 29°N to 37·5°N. All anthropometric and biochemical assessments were performed twice during a year (summer, winter). High BMI ( Z -score >1), low HDL cholesterol ( 150 mg/dl) were considered cardiometabolic risk factors. Results Serum 25-hydroxyvitamin D (25(OH)D) showed between-season variation, with significantly higher concentrations (mean ( sd )) in summer v . winter (43 (29) v. 27 (18) nmol/l; P r =−0·16; P r =−0·09; P =0·04) and total cholesterol ( r =−0·10; P =0·02) and di r ectly correlated with change of height-for-age Z -score ( r =0·09; P =0·04). Multiple stepwise linear regression analysis ( β ; 95 % CI) showed that winter serum 25(OH)D (−0·3; −0·4, −0·2; P v. girls: 9·7; 5·2, 14 · 1; P 33°N v. P =0·04) were predictors of change of serum 25(OH)D between two seasons. Conclusions Summertime improvement of vitamin D status was accompanied by certain improved cardiometabolic risk factors, notably serum TAG, total cholesterol and BMI, in children
