Abstract: Objective: To evaluate the effectiveness of an eight session intervention meant to increase physical activity and reduce the fat intake of seventh graders.

Design: Experimental study, described as a quasi-experimental design. Participants assigned to intervention or control group based on classrooms.

Subjects and Setting: N=103 seventh-grade students enrolled in a Midwestern urban public middle school. Response rate of 77% and a retention rate of 77%. All students could read and speak English. Intervention took place over a one-month period.

Interventions: Eight sessions held in a computer laboratory, with one student per computer. Interventions composed of two to three minute videos and 40-minute Internet based program on consciousness raising, self-reevaluation, improving access to healthy foods and physical activity, reducing barriers to healthy foods and exercise, and the benefits of eating healthfully and exercising.

Outcome Measures: Participant completion of workbook and tailored feedback as well as discussion board answers about eating and exercise habits. Food habit questionnaire.

Results: Students in the intervention group who completed more than half of the sessions showed an increase in moderate to vigorous exercise by an average of 22 minutes. Participants in the control group showed a decrease in activity of approximately 46 minutes (p=.05). Participants who participated in the intervention group and attended more than half of the sessions showed a decrease in percentage of dietary fat intake from 30.7% to 29.9% (p=.008). The control groupís numbers showed 31.5% dietary fat on the pretest, and 31.6% on the posttest. Interventions were effective for all racial groups in the study.

Conclusions: Limitations of study include a lack of measurement for family interventions, and potential lack of subject access to healthy food. Limitations also include subject self-report. Suggest that school nurses could utilize the interventionís modality. © Center on Media and Child Health
