Abstract
We determined the prevalence of general and central obesity and their relationship with blood pressure levels among adolescents in Abeokuta, Nigeria. We selected 423 adolescents from seven schools in Abeokuta, Nigeria, using a multistage random-sampling technique. Body mass index (BMI), waist circumference (WC) and blood pressures were measured. Twenty-one (5%) children had general obesity and 109 (24.5%) had central obesity. Of those with general obesity, 20 (95.1%) children were centrally obese. With simple linear regression analysis, BMI and WC explained 10.7 and 8.4%, respectively of the variance in systolic blood pressure (SBP), and 3.6 and 2.7%, respectively of the variance in diastolic blood pressure (DBP). Following logistic regression analysis, BMI was the major factor determining SBP levels (OR 0.8, 95% CI: 0.65-0.99, p < 0.05). BMI remains an important anthropometric screening tool for high blood pressure in Nigerian adolescents.
Highlights
We determined the prevalence of general and central obesity and their relationship with blood pressure levels among adolescents in Abeokuta, Nigeria
The mean weight, Body mass index (BMI) and waist circumference (WC) were significantly higher in the females (p < 0.05, p < 0.001, p < 0.001, respectively)
When the effects of BMI and WC on blood pressure were studied in a multiple logistic regression equation model (Table 4), BMI was significantly associated with high systolic blood pressure (SBP)
Summary
We determined the prevalence of general and central obesity and their relationship with blood pressure levels among adolescents in Abeokuta, Nigeria. Methods: We selected 423 adolescents from seven schools in Abeokuta, Nigeria, using a multistage random-sampling technique. Body mass index (BMI), waist circumference (WC) and blood pressures were measured. Results: Twenty-one (5%) children had general obesity and 109 (24.5%) had central obesity. With simple linear regression analysis, BMI and WC explained 10.7 and 8.4%, respectively of the variance in systolic blood pressure (SBP), and 3.6 and 2.7%, respectively of the variance in diastolic blood pressure (DBP). BMI was the major factor determining SBP levels (OR 0.8, 95% CI: 0.65–0.99, p < 0.05). Conclusion: BMI remains an important anthropometric screening tool for high blood pressure in Nigerian adolescents
