RESUMO
Mainstream preventive interventions often fail to reach poor populations with a high risk of cardiovascular diseases (CVDs) in Pakistan. A community-based CVD primary prevention project aimed at developing approaches to reduce risk factors in such populations was established by Heartfile in collaboration with the National Rural Support Program in the district of Lodhran. The project implemented a range of activities integrated with existing social and health service mechanisms during a three year intervention period 2000/01-03/04. These were targeted in 4 key settings: community health education, mass media interventions, training of health professionals and health education through Lady Health Workers. The project received support from the Department for International Development, U.K. At the community level, a pre-test-post-test quasi-experimental design was used for examining project outcomes related to the community component of the intervention. Pre and post-intervention (training) evaluations were conducted involving all health care providers in randomly selected workshops in order to determine baseline levels of knowledge and the impact of training on knowledge level. In order to assess practices of physician and non-physician health care providers patient interviews, with control comparisons were conducted at each health care facility. Significant positive changes were observed in knowledge levels at a community level in the district of intervention compared with baseline knowledge levels particularly in relation to a heart healthy diet, beneficial level of physical activity, the causes of high blood pressure and heart attack and the effects of high blood pressure and active and passive smoking on health. Significant changes in behaviors at a practice level were not shown in the district of intervention. However the project played a critical role in spurring national action for the prevention and control of non-communicable diseases and introducing sustainable public health interventions for poor communities in Pakistan.

OBJECTIVE: To investigate the effectiveness of posters as a tool, for imparting information related to high blood pressure. METHODS: The intervention involved hanging posters conveying information about blood pressure, in the waiting rooms of 339 health facilities. The impact of this intervention was assessed after 30 days of hanging the posters with the main assessment component of the survey aimed at the target audience at the facilities. 1017 people attending the facilities were interviewed. RESULTS: Mean age of this population was 40.4 (SD 11.06) years. There were 79% males and 21% females. 80.2% (n=816) of the respondents had noticed the posters. 84.5% of the people were of the opinion that the poster was good. 63.7% of the people understood the overall message of the poster correctly. Regarding change in behaviour, 96.7% (n=789) of the people thought that the poster was asking them to do something; 85.9% (n=501) of these got their blood pressure checked compared to 60.9% (n=14) of those who did not think the poster was asking them to do anything (p=0.004). Of those who said that the poster was asking them to do something, there were varied responses as to what they thought the poster was asking them to do. If the response was that they should have their blood pressure checked, it was taken as a correct response. 87.3% of those who said that the poster was asking them to get their blood pressure checked, actually got their blood pressure checked compared to 83.7% of those who did not understand this message (p=0.241). CONCLUSIONS: Given the limitations of the study it is difficult to assess the effectiveness of the poster in changing people's behaviour regarding blood pressure check up. This experience will serve as a pilot for a larger prospective study to assess poster as a tool for prompting people to get their blood pressure checked.
