The effect of participation in the WIC program on preschoolers' diets

OBJECTIVE: To evaluate nutrient, food intake, and snacking behavior by participation in the WIC (Special Supplemental Nutrition Program for Women, Infants, and Children) program. STUDY DESIGN: Secondary data analysis of a nationally representative cross-sectional survey conducted by USDA in 1994 to 1996 and 1998. METHODS: Statistical analysis was performed correcting for sample design effects and weighting for children in two income groups (<130%, n=1772 and 130% to 185% of poverty, n=689). RESULTS: Among WIC participants, the prevalence of snacking was significantly lower (68%) compared with nonparticipants (72%) (chi(2)=5.9, P=.01). For those <130% of poverty, WIC had a beneficial effect on the intake of fat, carbohydrates, added sugar, and fruit from the total diet as well as on added sugar from snacks. These were independent of food stamp participation. For those with higher incomes, the beneficial effects were limited to added sugar, iron density, and fruit intake for the total diet. A similar significant effect of decreased added sugar intake from snacks was also seen. CONCLUSIONS: Our results are in line with previous research showing beneficial effects of WIC participation among preschoolers, primarily for nutrients targeted by the program. This study shows that the effect can reach beyond those targeted nutrients.     

The effect of diazepam enema on the rectal mucosa of rats

The use of undiluted intravenous diazepam solution administered as an enema has been recommended for the acute management of seizures when intravenous access cannot be obtained. It is well absorbed, rapidly effective, and generally accepted as being safe when used in this manner. The effect of intravenous diazepam solution on the rectal mucosa has not been studied. This study demonstrates that there are no acute changes in the rectal mucosa of adult rats after administration of 10 to 20 times the recommended human dose.     

The effect of age, sex, race, and economic status on dental caries experience of the permanent dentition. Committee to Review the Ten-State Nutrition Survey of 1968-1970.

The Ten-State Nutrition Survey data show a consistent, dramatic, and meaningful difference in dental caries experience between black and white children at all ages. This difference transcends socioeconomic grouping, nutritional level, and developmental status. This study also has shown an apparently protective effect of poverty insofar as dental caries is concerned. Children from lower-income families experienced less dental caries than children from higher-income families.
