H. Wechsler et al., PROMOTING THE SELECTION OF LOW-FAT MILK IN ELEMENTARY-SCHOOL CAFETERIAS IN AN INNER-CITY LATINO COMMUNITY - EVALUATION OF AN INTERVENTION, American journal of public health, 88(3), 1998, pp. 427-433
Objectives. This study examined the effects of a school-based interven
tion designed to promote the consumption of low-fat white milk at lunc
htime in 6 elementary schools in an inner-city, primarily Latino neigh
borhood. Methods. A multifaceted intervention based on social marketin
g techniques was delivered at 3 randomly selected schools. The school
was the unit of assignment and analysis; 6902 children were involved i
n the study. Milk selection and consumption were measured by sampling
discarded milk and/or tallying milk carton disappearance at baseline,
immediately postintervention, and at 3 to 4 months follow-up. Results.
Immediately postintervention, the mean proportion of sampled milk car
tons that contained low-fat milk increased in the intervention schools
, from 25% to 57%, but remained constant at 28% in the control schools
. Differences between intervention and control schools remained signif
icant at 3 to 4 months follow-up. The intervention was not associated
with a decrease in overall milk consumption. Conclusions. A school-bas
ed intervention can lead to significant increases in student consumpti
on of low-fat milk.
