Area of Science:

• Public Health
• Health Communication
• Cardiovascular Disease Prevention

Background:

• Health education campaigns are crucial for cardiovascular disease (CVD) prevention.
• Low-resource settings require cost-effective health communication strategies.
• Evaluating intermediate impacts like knowledge and attitude change is vital for campaign assessment.

Purpose of the Study:

• To assess changes in knowledge and attitudes as intermediate measures of community impact.
• To evaluate the effectiveness of a health education campaign using newspaper articles for CVD prevention in Pakistan.

Main Methods:

• A 130-week health education campaign featuring prominently placed, illustrated newspaper articles by Heartfile was implemented nationwide in Pakistan.
• A cross-sectional telephone survey was conducted in a major city post-intervention to evaluate campaign reach and impact.
• Data analysis focused on readership, recall of articles, knowledge supplementation, and self-reported behavior changes regarding diet, exercise, and tobacco use.

Main Results:

• 93% of eligible newspaper readers recalled the Heartfile articles, with 87% reporting supplemented knowledge on diet, 77% on exercise, and 85% on smoking.
• Articles served as the sole information source for 5% (diet), 9% (exercise), and 4% (smoking).
• Reported behavior changes included dietary modifications (40%), exercise habit changes (39%), and reduced tobacco consumption (8%).

Conclusions:

• Newspaper articles are a valuable supplementary tool for health education within cardiovascular disease prevention programs.
• The Heartfile campaign in Pakistan offers a replicable model for similar low-resource health initiatives.
• This study highlights the potential of mass media, specifically newspapers, to drive significant public health awareness and behavioral shifts.
