Brief summary

Four California school districts will be randomized to early implementation of California's SB 19 Pupil Nutrition Act or to business as usual. Over 5000 4th, 5th and 7th graders will be evaluated at baseline, 4-month, and 16-month follow-up in order to determine if the SB 19 nutrition and physical activity policies have had an impact on students' risk of excess body weight. The impact of early implementation of SB 19 on academic achievement will also be assessed.

Detailed description

Four California school districts will be randomized to early implementation of California's SB 19 Pupil Nutrition Act or to business as usual. The nutrition provisions in SB19 include assuring that NO elementary school sells carbonated beverages at any time and that no middle schools sell carbonated beverages until after the end of the lunch hour each day. The nutrition provisions also include some restrictions on the sale of high-fat, high-sugar snack foods as well as encouragement to make fruits and vegetables more available to students. The legislation further encourages school districts to invest more heavily in providing students with opportunities to be physically active. High schools are NOT affected by this legislation. Over 5000 4th, 5th, and 7th graders from 28 schools will be evaluated at baseline, 4-month and 16-month follow-up in order to determine if the SB 19 nutrition and physical activity policies have had an impact on students' risk of excess body weight. The principal outcome measure is sex- and age-adjusted BMI percentile as determined from the CDC growthchart percentiles. Other measures include waist circumference, time to complete one mile run/walk, and blood pressure. The impact of early implementation of SB 19 on academic achievement will also be assessed, using students' standardized math and language arts achievement test scores.
