Screening school personnel for cardiovascular disease risk factors: short-term impact on behavior and perceived role as promoters of heart health.
BACKGROUND
Few controlled studies have evaluated the impact of community-based screening to detect risk factors for cardiovascular disease (CVD) on behavior change. This study examined the short-term impact of school-based screening on smoking, leisure time exercise, and fat consumption of personnel working in schools offered CVD risk factor screening. Also, the impact of screening on the perceptions that teachers have of their role in promoting heart health at school and the frequency of discussing heart health issues with students was investigated.


METHODS
The impact of screening was investigated in a before-after study design comparing behaviors of staff working in eight inner-city elementary schools offered the screening with those of staff working in eight matched comparison schools. Data were collected in self-administered questionnaires 2 weeks before and 4 months after screening.


RESULTS
A total of 209 subjects in the intervention schools completed the baseline questionnaire. Of these, 125 (59.8%) participated in the screening and completed the 4-month follow-up questionnaire. In the comparison schools, 135 of 177 subjects who completed the baseline questionnaire (76.3%) also completed the follow-up questionnaire. Multivariate analysis of covariance detected no changes in cigarette or fat consumption, but subjects exposed to the screening significantly increased their level of physical activity. Also, teachers exposed to screening increasingly supported the notion that teachers have a role in promoting heart-healthy behaviors among their students.


CONCLUSIONS
Although several methodological limitations might have influenced the results, these data suggest that screening and counseling for CVD risk factors is an effective strategy to positively influence level of physical activity. If screening does increase motivation and interest among teachers to become heart-health role models or educators, the benefits of school-based screening could extend well beyond those who actually participate.
