Background: Childhood obesity and related hypertension are major public health concerns globally. This study aimed to determine the prevalence of obesity and the associated risk of high blood pressure among Macedonian adolescents.Methods.The research was realized on a sample of 4091 adolescents, 19 from primary schools from the Central and East part of Republic of Macedonia. The sample (average age 12,4 ± 1,1 years) was separated in two subsamples according to the gender – 2116 boys and 1975 girls. Two anthropometric measures (IBP methodology) were taken, the body composition was determined according to the BIA, whereas the systolic and diastolic blood pressure were measured according to the standard methodology. Participants were categorized according to the international gender and age-specific BMI (kg/m2) cut-off points. The results were statistically processed according to proper statistical procedures (variance analysis and χ2test).Results. The percentage of overweight and obese adolescents, classified on the basis of the BMI criterion in this research is 35%. Macedonian adolescents from both genders with moderately increased or high BMI have higher values in the variables Height (cm), Weight (kg), Body fat (%), Fat mass (kg), SBP (mmHg) and DBP (mmHg) regarding the participants with normal body weight and lower values in the variable Muscular mass (p˂ 0.00). As per the blood pressure classification, hypertension was observed in 5.8% of boys and in 4.0% of girls. The relation between the nutritive status and blood pressure was determined (boys: 2= 35.327, p < 0.001;girls: 2 = 49.54, p < 0.001). Conclusion.Adolescents from both genders who have moderately increased or high level of body mass index (BMI) have higher blood pressure (systolic and diastolic) in comparison with the adolescents that have normal body mass index. Also, there is a relation determined between the nutritive status and blood pressure among boys and girls. Hypertension prevalence is increased as the body mass index increases. In the process of designing strategies and recommendations for improvement
