Risk factors of hypertension among adults aged 35–64 years living in an urban slum Nairobi, Kenya
Key result
The age-standardized prevalence of hypertension was 29.4%, with obesity significantly increasing the odds of hypertension (AOR 1.8) among adults in a Kenyan urban slum.
Population
1,528 adults aged 35 years and older living in Kibera slum Nairobi, Kenya, mean age 46.7 years.

Implication
Risk factor associations with hypertension in Nairobi slums should not yet change practice; leaves open need for longitudinal confirmation.
Study Design
Type
Cross-Sectional (n=1,528)
Structured PICO
P
Population
1,528 adults aged 35-64 years living in an urban slum in Nairobi, Kenya, were assessed to determine the prevalence and risk factors of hypertension.
O
Outcome
Prevalence of hypertension and associated risk factors
Main Result
Odds Ratio: 1.8 (95% CI 1.1–3.1)
Absolute Event Rate: 36% vs 21.9%
Hypertension affects nearly one-third of adults in a Kenyan urban slum, driven by risk factors such as obesity, wealth index, and physical inactivity.
Limitations
- Recall bias due to self-reported behavioral risk factors
- Potential under-reporting of discouraged behaviors such as alcohol and tobacco consumption
- Blood pressure based on average of two measurements at a single visit
- Cross-sectional design precludes establishing causality

Olack et al. (2015) conducted a cross-sectional in Hypertension (n=1,528). Obesity vs. Normal BMI was evaluated on Hypertension (AOR 1.8, 95% CI 1.1-3.1). The age-standardized prevalence of hypertension was 29.4%, with obesity significantly increasing the odds of hypertension (AOR 1.8) among adults in a Kenyan urban slum.
