What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Pre-hypertension (n=1079). Intervention: High BMI vs. Normal BMI. Primary outcome: Systolic pre-hypertension (OR 2.3, 95% CI 1.4-3.8).

What question did this study set out to answer?

To determine the prevalence of pre-hypertension and identify associated lifestyle cardiovascular disease risk factors in rural youth.

Key result

Among rural Nigerian adolescents, the prevalence of systolic pre-hypertension was 33.2%, and it was significantly associated with high BMI and older age.

Population

1,079 adolescents aged 15-18 years attending secondary schools in a rural setting in south-west Nigeria…

Implication

Supports BMI screening in rural Nigerian adolescents; hypothesis-generating for longitudinal studies on hypertension progression.

Key Points

To determine the prevalence of pre-hypertension and identify associated lifestyle cardiovascular disease risk factors in rural youth.
Surveyed 15–18-year-old adolescents (N=1079) in rural south-west Nigeria using a locally-validated cardiovascular disease risk assessment tool.
Measured body mass index, waist-hip ratio, and resting systolic and diastolic blood pressure.
Modeled gender-specific causal pathways to assess risk factors associated with pre-hypertension and overweight or obesity.
Systolic pre-hypertension occurred in 33.2% of adolescents, diastolic pre-hypertension in approximately 5%, and hypertension in less than 10%.
Older age and higher body mass index emerged as significant predictors of systolic pre-hypertension across both genders.
Preferences for fried foods predicted high body mass index specifically in females, whereas low breakfast cereal consumption was a predictor only in males.

Population

1,079 rural Nigerian adolescents aged 15-18 years attending secondary schools, assessed for prevalence of pre-hypertension and associated lifestyle cardiovascular risk factors.

Outcome

Prevalence of pre-hypertension (systolic and diastolic) and associated lifestyle cardiovascular disease risk factorssurrogate

Main Result

Odds Ratio: 2.3 (95% CI 1.4–3.8)

Rural Nigerian adolescents have a high prevalence of systolic pre-hypertension (33.2%) associated with high BMI and older age, highlighting the need for early lifestyle interventions.

Limitations

Cross-sectional design precludes inferring causal relationships.
Potential artifacts in blood pressure readings despite taking a second measurement for high initial readings.
Lack of biochemical profiles (e.g., lipid profiles), relying on fatness measures as proxies.
Data only captured from students attending school, excluding those who are absent or not enrolled.
Cross-sectional design cannot infer causal relationships
Potential artifacts in reading blood pressure despite second measurement
Did not assess biochemical profiles such as lipid profiles
Gender-imbalance in sample
Captured data only from students attending school, missing truants or non-enrolled adolescents

Odunaiya et al. (2015) conducted a cross-sectional in Pre-hypertension (n=1,079). High BMI vs. Normal BMI was evaluated on Systolic pre-hypertension (OR 2.3, 95% CI 1.4-3.8). Among rural Nigerian adolescents, the prevalence of systolic pre-hypertension was 33.2%, and it was significantly associated with high BMI and older age.
