The effects of a comprehensive community trial on cardiometabolic risk factors in adolescents: Isfahan healthy heart program
Abstract
BACKGROUND: This study aimed to assess the effects of a 6-year-long communityparticipatory
program including school-based interventions on mean values and prevalence of
cardiometabolic risk factors among adolescents.
METHODS: The interventions of this community trial, conducted from 2000 to 2007 in Iran,
targeted the whole population (of nearly two millions) living in two cities considered as the
intervention area (IA) in comparison with a reference area (RA). Data from surveys conducted
before and after interventions was used to compare the differences between the secondary
school students of the IA and RA.
RESULTS: The prevalence of hypercholesterolemia and hypertriglyceridemia declined
significantly in girls and boys in the IA (P < 0.01). The prevalence of high LDL-C decreased
significantly in the girls in the RA (P = 0.002). Among both sexes in the IA, the prevalence of
low HDL-C increased significantly (P < 0.001), whereas it decreased in the girls and boys in the
RA (P = 0.04). Although in the IA, the prevalence of overweight and obesity decreased
significantly in girls (P = 0.001), it increased in boys (P = 0.001) as well as in the girls of the RA
(P = 0.01).
CONCLUSION: By performing school-based interventions, our study was successful, at least in
part, in controlling some cardiometabolic risk factors in adolescents. Such modifications may
have long-term impacts on non-communicable diseases prevention in adulthood.
