Background: Epidemiological data on cardiovascular diseases in Palestine are scarce. We aimed to estimate the attributable risk of major modifiable cardiovascular risk factors contributing to prevalent coronary artery disease (CAD) and stroke in the Palestinian population in Gaza. More specifically, we compared the population living in and out of camps to assess the potential influence of this specific environmental parameter on cardiovascular epidemiology.
Methods: The prevalence of cardiovascular risk factors and their association with CAD and stroke were studied in a cross-sectional study carried out in the Gazan community among 2240 participants, aged ≥ 25 years. The population attributable risk fractions (PARF) were calculated using an adjusted odds ratio for CAD and stroke.
Results: The PARF of hypertension, diabetes and low physical activity were respectively at 33.8% (95%CI, 24.8-46.1), 22.3% (95% CI,16.3-30.4) and 16.2% (95% CI,11.9-22.0) for CAD. For stroke, hypertension, diabetes and high level of triglycerides had the highest impact, with PARF reaching 54.4% (95% CI, 32.1-95.1), 39.4% (95%CI,23.9-64.9), and 30.7% (95% CI,18.6-50.6), respectively. Hypertension, diabetes, low PA, and obesity were the factors with the strongest impact on CAD and stroke in women. When comparing the PARF in a population living in camps and those living out of camps, hypertension and diabetes remained the risk factors with the highest PARF for CAD or stroke in persons living in both areas with a slight difference.
Conclusion: A majority of CAD and stroke cases are attributable to major cardiovascular risk factors in the Gazan population. Interventions to reduce cardiovascular disease occurrence should primarily focus on the control of hypertension, diabetes, and obesity as preventable risk factors in this setting.
