KELISHADI, Roya et al. Cumulative prevalence of risk factors for atherosclerotic cardiovascular diseases in Iranian adolescents: IHHP-HHPC. J. Pediatr. (Rio J.) [online]. 2005, vol.81, n.6, pp. 447-453. ISSN 0021-7557. http://dx.doi.org/10.1590/S0021-75572005000800007.
OBJECTIVE: To evaluate the cumulative prevalence of atherosclerotic cardiovascular disease risk factors in a representative sample of Iranian adolescents. METHODS: The subjects of this cross-sectional study were 1,000 girls and 1,000 boys, ages 11-18 years, selected by multi stage-random cluster sampling from urban and rural areas of three cities in Iran. RESULTS: The prevalence of physical inactivity, dyslipidemia, smoking, high blood pressure and obesity (body mass index >95th percentile) were 66.6, 23.7, 8.7, 5.7 and 2.2%, respectively. Of subjects studied, 79.1% had at least one and 24.6% had two cardiovascular disease risk factors. The prevalence of physical inactivity was significantly lower in boys than girls [53.9 vs. 79.3%, respectively, OR 95%CI, 0.44 (0.39-0.51)]. The prevalence of smoking was higher in boys than girls [13.1 vs. 4.2%, respectively, OR 95%CI, 3.4 (2.4-4.9)]. CONCLUSION: Considering the high prevalence of cardiovascular disease risk factors in adolescents, age-appropriate and culturally sensitive interventions for lifestyle change are warranted, so that preventive measures can be taken in a timely manner.
