ABSTRACT

BACKGROUND:

Blood pressure of children increases with ages, and is related to anthropometric parameters, diet, sports, and other factors. To analyze relative factor of a little high blood pressure of children provides a scientific evidence for prevention and cure of primary hypertension.

OBJECTIVE:

To investigate correlation between blood pressure and anthropometric parameters among children.

DESIGN:

Cross-sectional study.

SETTING:

Department of Hygiene of Weifang Medical College.

PARTICIPANTS:

According to cluster sampling, 1 546 pupils in grade three or four were selected from a primary school for physical examination and questionnaires. Totally 1 508 pupils with complete data were regarded as the subjects.

METHODS:

Partial correlation analysis was used to analyze correlation between blood pressure and anthropometric parameters among children.MAIN OUTCOME

MEASURES:

Correlation among anthropometric parameters, systolic pressure and diastolic pressure.

RESULTS:

① Correlation coefficients of systolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.078, 0.166, 0.337, 0.313 and 0.304 (P ＜ 0.01). ② Correlation coefficients of diastolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.047, 0.120, 0.268, 0.271 and 0.251 (P ＜ 0.01). ③ After controlling two effect of anthropometric parameters on each other, systolic pressure and diastolic pressure were only correlated with height and chest circumference (P ＜ 0.01), but was not correlated with age, sex and body mass (P ＞ 0.05).

CONCLUSION:

After controlling the effect of anthropometric parameters on each other, systolic pressure and diastolic pressure of children were positively correlated with height and chest circumference.
