Prevalence and risk factors of pre-hypertension and high blood pressure among adolescents in Cameroonian schools.

Abstract

Blood pressure (BP) is the main driver of mortality with 12.8% of all deaths worldwide. Adolescents are not spared, precisely in Cameroon where they constitute more than half of its population. The objective of our work was to describe the prevalence and risk factors of pre-hypertension and high blood pressure (HBP) among adolescents in Cameroonian schools. Descriptive study over 5 months; from January to May 2019. The study population consisted of students from private and public schools in the city of Douala. Sociodemographic, anthropometric, and personal background data were collected. Physical activity (PA) was assessed using the short International Physical Activity Questionnaire (IPAQ). Multivariate logistic regression was used to determine factors associated with pre-hypertension and HBP. Differences were considered significant for p<.05. We recruited 771 students with an average age of 16±1 years with female predominance (51.4%). The prevalences of pre-hypertension and HBP were 6.6% and 3%, respectively. Overweight/obesity (OR=4.6; p<.0001), hyperglycemia [(OR=4.06; p=.001)] physical inactivity (OR=1.85; p=.019), and public institutions (OR=1.87; p=.02) were associated with pre-hypertension. Similarly, overweight/obesity (OR=2.99; p=.022), hyperglycemia (OR=14.05; p<.0001), and physical inactivity (OR=8.58; p<.0001) were correlated with HBP. Pre-hypertension and HBP are high in Cameroonian school adolescents and their risk factors are overweight/obesity, hyperglycemia, and physical inactivity.
