Prevalence of hypertension and its associated factors among healthcare workers in the Gaza Strip, Palestine: a cross-sectional study

Background and objectives Hypertension (HTN) is one of the leading risk factors of cardiovascular diseases and accounts for substantial morbidity and mortality worldwide. We aimed to estimate the prevalence of HTN and its associated factors among healthcare workers (HCWs) at the Gaza Strip's governmental hospitals and primary healthcare centres (PHCs). Design Cross-sectional study. Settings, participants and methods The study with multistage stratified random sampling was conducted in 10 hospitals and 15 PHCs of the Ministry of Health in Palestine from February to May 2020. Self-administered face-to-face interview questionnaires were used to collect information on sociodemographics, lifestyles, health profiles and health-related risk factors. The anthropometric parameters were measured, including height, weight, waist circumference (WC), hip circumference (HC), and systolic and diastolic blood pressure. HTN was diagnosed by taking any antihypertensive medication, or the mean blood pressure ≥140/90 mm Hg. The SPSS V.26.0 software was used for data analyses. Results A total of 1850 participants, with a mean (SD) age of 36.6 (7.9) years, including 12.2% physicians, 65.3% nurses, 18.1% paramedics and 4.4% non-medical personnel, were included in this study. The prevalence of HTN among HCWs was 8.4%. The associated modifiable factors of HTN were body mass index (BMI), smoking, coffee intake and physical activity (p<0.05). The anthropometric parameters were considerably higher in HTN than in non-HTN (p<0.05). In adjusted models, age, BMI, WC, HC, type of work, workplace, working experience, smoking, coffee intake, physical activity and family history of HTN showed statistically significant associations with HTN (p<0.05). Conclusions The modifiable factors, including smoking, coffee intake, physical activity and BMI, were associated with the risk of HTN. These findings indicate that effective efforts in maintaining a healthy lifestyle are needed to prevent HTN among HCWs.
