Abstract

Background: In the past, diastolic hypertension was the main criterion for treatment, but currently, systolic pressure is the main criterion because it was thought that Isolated Diastolic Hypertension (IDH) is not associated with complications. Studies later revealed that IDH carries significant risks. Quantifying the magnitude and risk factors of IDH in the community is essential for all intervention strategies.

Aims: This study aims to determine the prevalence, risk factors, predictors, treatment modalities and lifestyle practices of IDH adult patients in the Kingdom of Saudi Arabia (KSA).

Study Design: Cross-sectional study.

Methods: A community-based cross-sectional study using STEPwise approach among adults using a multistage, stratified, cluster random sample was carried out. Data were collected using questionnaires which included socio-demographics, blood pressure, biochemical, anthropometric measurements and lifestyle practices. Statistical analysis included calculating means and standard deviations, proportions, univariate and multiple logistic regression analysis.

Results: Of a total 4562 subjects, 180 (3.95%) suffered from IDH, which was significantly related to age, gender, employment, smoking, diabetes mellitus, obesity and hypercholesterolemia. More than 93% were using some form of treatment, with 77.2% on prescribed drugs, 63% using diet, and 23% using exercise. Significant predictors of IDH were retirement and hypercholesterolemia.

Conclusion: IDH is associated with some sociodemographic characteristics and co-morbidity. Given the risk of cardiovascular disease associated with IDH, the findings of this study emphasize the need for diagnosing the disease in middle-aged persons focusing on the modifiable risk factors of IDH.
