The accelerating rate of youth obesity in the United States indicates that this generation of children will grow into the most overweight generation of adults in United States history. The purpose of this study was to determine the relationships between body mass index, daily step count, and television viewing time in children ages 10 to 13. Participants included 66 girls and 87 boys from three private schools in the Midwest. Students were from various ethnic groups (62% Caucasian, 30% Hispanic, 8% Other). Sixty-two percent of the students qualified for the free and reduced lunch program. Data were collected during four consecutive school days (Monday-Thursday). First, height and weight values were charted on the Center for Disease Control and Prevention Body Mass Index Values Table to obtain BMI scores. Second, the Self Administered Physical Activity Checklist (SAPAC) was used to measure mean television viewing time. Finally, the Yamax Digi-Walker SW-200 was used to record step counts. Results indicated mean scores for body mass index at 20.2 for girls and 20.4 for boys. Mean television viewing time for both genders was 2.5 hours/day. Boys recorded more steps than girls with scores of 12,283 and 10,316, respectively. Pearson correlation for average step count and BMI was -.191, which was significant at the 0.05 level (2-tailed). Average step count and TV viewing time results indicated a significant correlation of -.244 at the 0.01 level (2-tailed). BMI and TV viewing time indicated a significant correlation of .484 at the 0.01 level (2-tailed). The present findings have implications for schools to provide and promote interventions and physical education curriculums which allow for sufficient, high-quality physical activity during school days. If children are encouraged to be active at school, they are more likely to engage in desirable physical activity, and remain active after school. Future research should continue to focus on habitual activity levels with this population to challenge whether the current recommended levels of steps per day is adequate.Keyword(s): exercise/fitness/physical activity, obesity issues, physical education PK-12
