Trial Information


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.
