Community-based education classes for hypertension control. A 1.5-year randomized controlled trial

Area of Science:

• Public Health
• Cardiovascular Disease Prevention
• Health Education

Background:

• Community-based hypertension control is crucial for primary prevention of cardiovascular disease.
• Hypertension management often involves lifestyle modifications and pharmacotherapy.
• Effective community programs are needed to support long-term blood pressure management.

Purpose of the Study:

• To evaluate the effectiveness of a community-based education program on hypertension control.
• To assess the impact of lifestyle interventions on systolic and diastolic blood pressure.
• To determine if non-pharmacological methods can reduce the need for antihypertensive medication.

Main Methods:

• A 1.5-year randomized controlled trial involving 111 untreated adults (35-69 years) with elevated blood pressure.
• Intervention group received 8 education classes focusing on diet (sodium, milk, alcohol, sugar) and exercise (brisk walking).
• Control group received 2 education classes; blood pressure and behavioral changes were monitored.

Main Results:

• The intervention group showed a significant reduction in mean systolic blood pressure (5-6 mm Hg) at 6 months and 1.5 years compared to the control group.
• Fewer participants in the intervention group (9%) required antihypertensive medication versus the control group (24%).
• Increased adherence to reduced sodium intake and increased milk consumption was observed in the intervention group.

Conclusions:

• A community-based health education program can effectively reduce and maintain lower systolic blood pressure levels through non-pharmacological interventions.
• Lifestyle modifications, including dietary changes and physical activity, are key components of successful community-based hypertension control.
• This program offers a viable strategy for primary prevention of cardiovascular disease by managing hypertension at the community level.
