Nutrition and exercise in middle-school childrenDietary fat intake significantly reduced in intervention-group girls for AA, Latino, AI/AN, and white children; significantly increased physical activity among those with lowest income among AA, Latino, Asian, and white childrenQuasi-experimental evaluation of a 4-session Internet and video intervention with healthy snack and gym labs; intervention occurred in 2 urban, low- to middle-income middle schools (gym lab in 1) in the MidwestAA: n = 58; white: n = 47; Asian: n = 9; Latino: n = 4; AI/AN: n = 4Small sample sizes from only 2 schools; unclear what control group received (if anything); unclear when postintervention evaluation occurred; no overall difference between intervention and control children in fat intake reduction; both groups actually decreased their amount of physical activity135
Immunization rates among 0- to 2-y-oldsNo statistically significant differences (vs white children) in postintervention population immunization rates for 24-mo-olds among AA and Latino children; no statistically significant difference (vs white children) in postintervention population immunization rate for Latino (but not AA) 12-mo-oldsPrepopulation/postpopulation study in Monroe County, New York, of impact of community-wide reminder, recall, and outreach system for childhood immunizations administered by lay outreach workers in 8 practices (expanded to 10 after 4 y). Outcomes were monitored in a 10% random sample selected from suburban practices and a 25% random sample from urban practices.Total sample: N = 20 132a9%–74% of cohort (depending on study region) did not receive intervention; immunization rates unadjusted (not adjusted for any potential confounders)136
