Nutrition-education program improves preschoolers' at-home diet: a group randomized trial.

OBJECTIVE: This study evaluated whether a nutrition-education program in child-care centers improved children's at-home daily consumption of fruits and vegetables, at-home use of low-fat/fat-free milk, and other at-home dietary behaviors. MATERIALS AND METHODS: Twenty-four child-care centers serving low-income families were matched by region, type, and size, and then randomly assigned to either an intervention or control condition. In the 12 intervention centers, registered dietitian nutritionists provided nutrition education to children and parents separately during a 6- to 10-week period. They also held two training sessions for center staff, to educate them on healthy eating and physical activity policies at the centers, and distributed weekly parent newsletters that included activities and recipes. Parents (n=1,143) completed a mail or telephone survey at baseline and follow-up to report information on their child's fruit, vegetable, and milk consumption and other dietary behaviors at home. This study used general and generalized linear mixed models to evaluate program impacts, while accounting for the clustering of children within centers. This study included child age, child sex, household size, respondent race/ethnicity, respondent age, and respondent sex as covariates. RESULTS: The program had a substantial impact on children's at-home daily consumption of vegetables and use of low-fat/fat-free milk. This study also found a significant increase in the frequency of child-initiated vegetable snacking, which might have contributed to the significant increase in vegetable consumption. The program did not have a significant impact on fruit consumption or parental offerings of fruits and vegetables, child-initiated fruit snacking, or child fruit consumption. CONCLUSIONS: This intervention in child-care settings that emphasized children, parents, and teachers significantly increased at-home vegetable and low-fat/fat-free milk consumption among low-income preschoolers.

Factors influencing inadequate and excessive weight gain in pregnancy: Colorado, 2000-2002.

OBJECTIVES: To identify the biological, psychosocial, and behavioral characteristics that are associated with inadequate and/or excessive weight gain in pregnancy. METHODS: Univariate, bivariate, and multiple logistic regression analyses were conducted using data from Colorado's 2000-2002 Pregnancy Risk Assessment Monitoring System (PRAMS). Independent variables included biological risk factors (prepregnancy BMI, parity, preterm labor, maternal morbidity), psychosocial risk factors (pregnancy intention, WIC and Medicaid enrollment, area of residence, age, race/ethnicity, education, and stressors), and behavioral risk factors (smoking and drinking alcohol in the last trimester of pregnancy). RESULTS: In the bivariate analysis, all the biological risk factors were significantly associated with the pregnancy weight gain distribution, as were several of the psychosocial risk factors (WIC and Medicaid enrollment, area of residence, race/ethnicity, and maternal education). Smoking and alcohol use were not significant. After controlling for other variables through logistic regression, the only characteristics associated with inadequate weight gain were parity, underweight or obesity, preterm labor, nausea, residence in a rural area, low levels of education, and smoking. The characteristics associated with excessive weight gain were overweight or obesity, high blood pressure, and having 12 years of education. CONCLUSION: Having a pre-pregnancy BMI above 29 greatly increases the risk for both inadequate and excessive weight gain. Unfortunately, obesity, like the other major risk factors identified here (maternal education and parity) are not modifiable after a given pregnancy begins. To address these problems, a sustained approach to women's health, education, and well-being across the lifespan will be required, rather than a reliance upon targeted interventions during pregnancy.
