Community preventive programs appear to be effective at reducing the 10-year CVD risk according to systematic reviews of the literature [4,5]. There is a wide range in the degree of risk reduction among the different CVD preventive programs; some of them have marginal effects limiting their feasibility to only high risk communities . Insufficient information exists as to the optimal intervention and duration for community CVD preventive programs; however, one review demonstrated that longer interventions, greater number of interventions, and matching intervention with support appear have a positive correlation [4,5].
The cost associated with multi-year and multi-intervention primary CVD prevention programs is a problem for cash strapped communities, inner-city and rural communities in particular. For these communities, the ideal program is a onetime, low cost intervention that produces immediate and long lasting changes.
We surveyed all attendees to De Todo Corazón Women’s Conference that took place in Austin, Texas. Our primary goal was to determine the effectiveness in terms of immediate knowledge gain of a one-time, low cost CVD community teaching program for Hispanic Women.
Participants received pre- and post-conference questionnaires and handouts about hypertension and stroke from the Center for Diseases and Control at the registration desk, where they were asked to complete the pre-conference questionnaire right away before the beginning of the activities and the post-conference questionnaire at the end of all the activities. The questionnaires had written instructions when and how to complete them. The pre-conference questionnaire asked demographics (i.e. age group, gender, marital status, level of education, primary language(s), and race/ethnic group) and ten multiple choice questions about CVDs, primary prevention and early symptom recognition. The post-conference questionnaire asked the same ten multiple choice questions plus four five-point Likert scale questions to rate the talk, presenter, slides, and handouts.
Both questionnaires, including the Spanish versions, had been previously validated using small group presentations. The target language level was 6th grade. The topics of the questions were covered throughout the different activities of the event. The first year resident had previously received training on how to deliver an oral presentation from an experienced educator. Analysis was conducted using descriptive statistics, t-tests, and regression models. The study was exempt from IRB approval under 45 C.F.R.§46.101(b)(2),(3), and (5).

Participants with middle school education had the highest gains in score (on average 5.2 points) (p>.0001), all of which were Hispanics, followed by participants with the lowest pre-conference scores (see Figure 3). As to age and race/ ethnic group, participants who identified themselves as African-American and in the age groups 26 – 35 and 66 – 75 years old also increase the average post-conference scores, although not statistically significant.

Figure 4 presents how participants rated on a 5-point Likert scale the importance of the talk, the presenter, the slides, and the handouts. Due to the lack of data variability, all 5-poiint Likert scales were summed up to form an overall satisfaction score to find any association with the other variables. African- American participants were significantly less satisfied with the overall presentation even though the gender, race and language concordance with the resident physician delivering the talk (p .0079). Participants aged 56-65 and those with a middle school education or less were somewhat more satisfied (p .03 and .05, respectively).
