Motivational interventions in community hypertension screening
American Journal of Public Health
|April 1, 1977
Summary
Home visits by trained community members are more effective for identifying new hypertension cases than passive methods like letters or gift offers. Active outreach significantly increases the detection of previously undiagnosed high blood pressure.
Area of Science:
- Public Health
- Cardiovascular Health
- Community Outreach
Background:
- Hypertension is a major public health concern, particularly in urban, predominantly Black communities.
- Effective strategies are needed to increase blood pressure measurement (BPM) uptake and identify undiagnosed hypertension.
- Previous motivational techniques have shown varying degrees of success in community health interventions.
Purpose of the Study:
- To compare the effectiveness of different motivational interventions for encouraging community residents to undergo blood pressure measurements.
- To identify which outreach strategies yield the highest number of newly diagnosed hypertensive individuals.
- To assess the impact of passive versus active motivational techniques on hypertension detection.
Main Methods:
- Five comparable inner-city areas with predominantly Black populations were selected for the study.
- Four areas received different motivational interventions, including home visits and informational mailings.
- One area served as a control group, receiving no specific intervention.
Main Results:
- Home visits by community members trained in blood pressure measurements (BPMs) significantly increased the identification of new hypertension cases compared to passive methods.
- Informational letters, even those specifying visit times, did not reduce refusals or improve the yield of new hypertension diagnoses.
- Passive motivational techniques identified a higher proportion of previously known hypertensive individuals than active outreach efforts.
Conclusions:
- Active, in-home outreach by trained community members is a highly effective strategy for detecting previously undiagnosed hypertension.
- Passive motivational techniques are less effective for identifying new cases but may reach individuals with known hypertension.
- Future interventions should prioritize active outreach strategies for maximizing hypertension case finding in community settings.
