Cardiovascular diseases

Lipid disorders, arterial hypertension, cigarette smoking, overweight and physical inactivity are known risk factors of coronary artery disease. Control of the factors since adolescence may reduce cardiovascular morbidity and mortality in adulthood. Purpose of the study was to assess prevalence and trends of the cardiovascular risk factors among adolescent population in Novosibirsk during the reforms (1989-2003).

Methods: Four cross-sectional surveys of representative samples of school children aged 14-17 since 1989 were carried out (total – 2569). Body mass index (BMI, kg/m2), blood pressure, serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured. Self-report of smoking (1 cig/week and more) and physical inactivity (2 h/week and less) was obtained. Diet was estimated using 24-hour dietary recall.

Results: According to NCEP-peds criteria, prevalence of high TC (200 mg/dl and more) significantly decreased from 22% to 8% (P < 0,01) in males and from 32% to 17% (P < 0,05) in females. Similar trends were found in prevalence of high LDL-C and low HDL-C. According to the 4th Report of the NHBPEP Working Group, arterial hypertension also decreased from 23% to 13% in boys (P < 0,05) and from 20% to 7% in girls (P<0,05). Frequencies of overweight (BMI ≥ 23 kg/m2) decreased from 18% to 11% in boys (P<0,05) and from 22% to 10% (P<0,05) in girls. Trends in diet showed significant decreasing of total energy intakes (from 3021 to 2205 kcal in boys and from 2300 to 1779 kcal in girls) and basic nutrient intakes (proteins, fats and carbohydrates). Cigarette smoking rate in boys decreased from 45% in 1989 to 27% in 2003; the prevalence of girls’ smoking increased from 19 to 27%. Physical inactivity rate was high in boys (49-55%) and girls (83-73%).

Conclusion: Obtained data indicate on similar trends to reduction in classical CVD risk factors, energy intake and life style changes among Siberian adolescents during the period of socioeconomic reforms in Russia.
