[Blood pressure levels of 2438 Hasakh children in the Yili region of Xinjiang Province].

OBJECTIVE

To study blood pressure levels, the prevalence of hypertension and factors associated with the development of hypertension in Hasakh children in the Yili region of Xinjiang Province.

METHODS

A total of 2438 Hasakh school children from the Yili region of Xinjiang Province were sampled by stratified random cluster sampling method between May and June 2009. Height, weight, waist circumference, hip circumference, skinfold thickness and blood pressure were measured. Body mass index (BMI) was calculated.

RESULTS

Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 94±13 mm Hg and 60±9 mm Hg respectively in the 2438 children, and both averages were lower than in the Han children. Hypertension was noted in 138 children (5.66%). The prevalence of hypertension in girls (6.97%, 84/1206) was higher than in boys (4.38%, 54/1232) (P<0.05). The prevalence of hypertension and blood pressone were positively correlated with BMI, waist circumference, hip circumference, skinfold thickness circumference, gender and age.

CONCLUSIONS

Average blood pressure levels in Hasakh children in the Yili region of Xinjiang Province are lower than in domestic age-matched Han children. The prevalence of hypertension in girls is higher than in boys. Obesity is highly correlated with the development of hypertension.
