RESUMO
HEALTHY was a 3-year middle school-based primary prevention trial to reduce modifiable risk factors for type 2 diabetes in youth. The study was conducted at seven centers across the country. This paper describes the recruitment and retention activities employed in the study. Schools and students were the focus of recruitment and retention. Each center was responsible for the recruitment of six schools; eligibility was based on ability to enroll a sufficient number of predominately minority and lower socioeconomic status students. Study staff met with district superintendents and school principals to verify the eligibility of schools, and to ascertain how appropriate the school would be for conducting the trial. Sixth grade students were recruited employing a variety of techniques; students and their parents did not know whether their school was randomized to the intervention or control arm. This cohort was followed through sixth, seventh and eighth grades. In the eighth grade, an additional sample of students who were not originally enrolled in the study was recruited in a similar manner to participate in data collection to allow for cross-sectional and dose-response secondary analyses. Parents signed informed consent forms and children signed informed assent forms, as per the needs of the local Institutional Review Board. Parents received a letter describing the results of the health screening for their children after data collection in sixth and eighth grades. Retention of schools and students was critical for the success of the study and was encouraged through the use of financial incentives and other strategies. To a large extent, student withdrawal due to out-migration (transfer and geographical relocation) was beyond the ability of the study to control. A multi-level approach that proactively addressed school and parent concerns was crucial for the success of recruitment and retention in the HEALTHY study.

The HEALTHY study was a randomized, controlled, multicenter, middle school-based, multifaceted intervention designed to reduce risk factors for the development of type 2 diabetes. The study randomized 42 middle schools to intervention or control, and followed students from the sixth to the eighth grades. Participants were a racially, ethnically and geographically diverse cohort from across the United States. Here, we describe the conceptual underpinnings and design of the social marketing-based communications component of the HEALTHY study intervention that combined changes in the school nutrition and physical education (PE) environment with behavior change initiatives. The communications intervention component coordinated multiple elements to deliver campaigns that served to integrate and support all aspects of the HEALTHY intervention. The campaigns unfolded across five semesters of middle school, each targeting a specific theme related to the HEALTHY objectives. Communications campaigns comprised (1) core elements such as branding, posters, banners and visual and verbal messaging, (2) student events supporting the nutrition, PE and behavior intervention components through the application of social marketing and communications strategies, including the incorporation of student-generated media and (3) distribution of premiums and theme enhancers to extend the visibility of the study beyond the intervention environment. Formative research conducted with students, parents and school administrators was used to refine the communications strategy. Student peer communicators selected from the student body were involved to influence the normative student environment. Marketing and creative design experts developed a brand, logo, activities and materials. In the latter half of the study, student-generated messages and media were used to reflect local interests and culture and enhance peer influence. The HEALTHY intervention delivery and impact were strengthened by the communications strategies. The HEALTHY experience provides practical considerations for systematically incorporating a social marketing-based communications approach within future school-based health behavior interventions.

The purpose of this study was to describe cardiovascular (CV) health promotion practices of nurse practitioners (NPs) and physicians (MDs). Clinical practice was described for three age groups of children both with and without parental premature heart disease. Differences in clinical practice by type of provider and by age and risk level of the child were examined. A 42-question survey was mailed to all family NPs in North Carolina and to MDs randomly selected from the roster of the North Carolina Academy of Family Physicians; 94 responded. A high level of blood pressure measurement for all children and counseling regarding smoking for 13 to 19 year olds was found among all participants. Fewer health promotion activities were reported for other risk factors for the oldest group and for the younger children in general. Health promotion practices increased with the age of the child. Nurse practitioners had significantly higher total CV health promotion scores than did MDs, regardless of the age or risk level of the child. An increase in counseling about prudent diet and increased physical activity is needed for all children, regardless of risk level. In addition, there should be an increase in CV health promotion activities with younger children.
