Abstract Objective To investigate the association between the development of hypertension and nutrition in school-age children in Fengdu County of Chongqing, China. Methods A total of 8 033 children from 2 public primary schools in Fengdu County of Chongqing, whose registered residence was in the subdistricts where the two schools were located, were selected as study subjects using cluster random sampling. Body height, body weight, and blood pressure were measured, and the semi-quantitative food frequency questionnaire was used for dietary survey. The association between body mass index (BMI), dietary nutrients, and the development of hypertension in children was analyzed. Results A total of 7 538 children were enrolled for analysis. The detection rates of obesity, overweight, and hypertension were 9.11%, 12.27%, and 11.83% respectively. In children with obesity and overweight, the detection rate of hypertension was 33.62% and 17.84% respectively, 4.02 and 2.13 times that in normal children. The multivariate logistic stepwise regression analysis revealed that increased intake of calcium and sodium increased the risk of hypertension (OR=1.003 and 1.002 respectively), while the increased iron intake and calcium intake per unit body weight reduced the risk of hypertension (OR=0.979 and 0.926 respectively). Conclusions The prevalence of hypertension and obesity in school-age children in Fengdu County of Chongqing is high. BMI and dietary nutrients are closely associated with the development of hypertension in children. Active control of body weight, adjustment of dietary structure, and limitation of sodium intake should be adopted to reduce the development of hypertension in school-age children.
