title: Primary hypertension among a population of Nigerian secondary school adolescents: Prevalence and correlation with anthropometric indices: A cross-sectional study.
abstract: OBJECTIVE
  To assess the prevalence of primary hypertension and its correlation with anthropometric indices among a population of Nigerian adolescents.
  
  
  METHODS
  A cross-sectional study of secondary school adolescents aged 10-19 years in Enugu, Nigeria, using multi-staged sampling method. Anthropometry and blood pressures were measured using standardized instruments. Data analysis was with the Statistical Package for Social Sciences (SPSS) Version 20.0 (Chicago, IL, USA).
  
  
  RESULTS
  A total of 2419 adolescents (mean age, 14.80 ± 2.07 years) were included in the study. Prevalence of hypertension was 10.7%. Systolic and diastolic hypertension were observed in 232 (9.6%) and 85 (3.5%) of the participants, respectively. Forty-two of the 137 obese (30.7%) compared to 158 among the 1777 (7.7%) with normal body mass index (BMI) (P < 0.001) had systolic hypertension. Waist circumference (r = 0.37) and BMI (r = 0.37) significantly and positively correlated with systolic hypertension.
  
  
  CONCLUSIONS
  Obese and overweight adolescents had higher prevalence of primary hypertension than their counterparts with normal BMI.
