The effects of a comprehensive community trial on cardiometabolic risk factors in adolescents: Isfahan Healthy Heart Program
This study aimed to assess the effects of a 6-year-long community-participatory program including school-based interventions on mean values and prevalence of cardiometabolic risk factors among adolescents.
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.
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).
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.

ABSTRACT: BACKGROUNDSustainability is the core of a successful health-related intervention program. This study was conducted to evaluate the sustainability of interventions of the Heart Health Promotion from Childhood (HHPC) project, one of the 10 interventional projects of the Isfahan Healthy Heart Program.METHODSThe evaluation of HHPC included administrating surveys to 500 elementary and middle, and 500 high school students. The study participants were randomly selected from all schools in Isfahan. The questionnaires were administered by interviews to evaluate the sustainability of interventions.RESULTSThe results of interviews showed that interventions were sustainable in 100% of elementary school, 99% of middle school, and 87% of high school students. Training of healthy lifestyle behaviors was significantly higher in all-girls middle schools (P < 0.001). Daily morning exercise was more frequent in girls high schools (P < 0.001), while selling unhealthy food was more frequent in boys high schools (P < 0.001). The participants attributed the success of the program mostly to students’ agreement and cooperation.CONCLUSIONEven though 5 years have passed since the end of the HHPC project, many of the interventions have been continued at the schools, often because healthy behaviors have become institutionalized in the target population. However, now all schools have the same level of sustainability, especially the middle and high schools, and all-boys schools. Therefore, it is important for future projects to place additional emphasis on these institutions for future school-based interventions.03/2014; 10(2):107-117.

ABSTRACT: Obesity is one of the most important underlying risk factors for chronic disease. Dramatically increasing and following complication of obesity should be alerted to health politicians and practitioners to prevent associated health risks. This review aimed to give a better insight into the prevalence of obesity and overweight in different areas of Iran. All published internal (SID, Irandoc, Iranmedex), and international (Web of Knowledge, Pubmed, Scopus) source studies, reported the prevalence of overweight/obesity among normal population samples, during Jan 2005 through Jan 2014, were assessed in this review. Paper selection processes were done by two researchers separately. Studies which met the eligible criteria were included in this review. One hundred ninety three eligible studies enter into our review. Of 193 final selected studies, 86 (15 national, 71 sub national) of them were reported the prevalence of obesity/overweight in adult, and 107 studies (11 national, 96 sub national) in under-18 by individual. The range of overweight and obesity prevalence in national studies in adult, was 27.0-38.5 (95% CI: 26.8-27.1, 37.2-39.8), and 12.6-25.9 (95% CI: 12.2-13.0, 24.9-26.8), separately. In under-18 the range of overweight and obesity prevalence in national studies were 5.0-13.5 (95% CI: 4.5-5.5, 13.4-13.6), and 3.2-11.9 (95% CI: 3.0-3.4, 11.3-12.4). Obesity as an important public health problem has been discussed in recent few decades worldwide. Although the national reported prevalence of obesity in Iran was not considerably diverse, but remarkable differences were seen in the sub national prevalence which must be noticed more in political health programs especially among women and children.12/2014; 13(1):121.

ABSTRACT: Background:Metabolic syndrome (MetS) is more prevalent among Iranian adolescences. This study aimed to find the relationship between obesity and MetS among different education grades of Iranian adolescence.Materials and Methods:Overall, 1039 junior high school and 953 high school students were selected using multistage random sampling. Fasting blood sugar, total cholesterol, triglyceride (TG), and high-density lipoprotein cholesterol (HDL) were measured. Trained individuals measured waist circumference and blood pressure. MetS was defined according to the De Ferranti definition.Results:The prevalence of overweight and obesity was 12.6% and 6.2% in junior and 11.5% and 4.3% in high school students, respectively. Obese subjects in both grades have higher waist circumference, systolic and diastolic blood pressure, and triglyceride than comparable groups. Multiple logistic regression models showed that overweight and obesity were strongly associated with MetS components analyzed. Compared to normal-weight children, overweight and obese in junior high school students were 1.47 and 2.23 times more likely to be having high TG, respectively, whereas overweight and obese in high school-students were also more likely to have elevated TG [ORs 1.94 (1.28-2.94), 4.96 (2.39-10.3) respectively].Conclusion:Obese children have the highest prevalence of MetS. Prevalence of MetS-related components has reached high level among Iranian adolescences that were overweight or obese.07/2014; 18(4):569-73. DOI:10.4103/2230-8210.137523
