[Arterial pressure mean values and distribution, and relation to duration of residence in the North in school children living in the north of Tumen region].

AIM: To elicit regularities significant for epidemiological situation by arterial hypertension among schoolchildren of Tumen North with reference to duration of living in the North. MATERIAL AND METHODS: 2525 schoolchildren (the response 85.3%) aged 7-15 years entered a one-stage epidemiological study. RESULTS: Tables were made of arterial pressure distribution in the schoolchildren population. The pressure was higher in children living in the North for more than 5 years. Arterial hypertension was registered in 12.7% of the examinees (14.1% of boys and 11.6% of girls). CONCLUSION: Prevalence of arterial hypertension in schoolchildren living in the North was high. A correlation was found between mean arterial pressure and duration of the exposure to North conditions.
