Mother and Infant Predictors of Rapid Infant Weight Gain.

Objective. To examine characteristics of the infant and mother associated with rapid infant weight gain (RIWG). Methods. Electronic health records (N = 4626) of term infants born were reviewed. Multivariable logistic regression examined the presence of RIWG (vs not) using participant characteristics in the whole sample and in stratified groups. Results. The prevalence of RIWG was 18.7%. Predictors of RIWG were infant male sex, younger infant gestational age, firstborn (vs later born) status, maternal Black or Other (Asian, American Indian, etc), non-Hispanic race/ethnicity (vs White non-Hispanic), Medicaid (vs non-Medicaid insurance), and maternal cigarette smoking status (vs never smoker). The regression model explained between 7.0% and 11.4% of the variance in RIWG. There were few differences in predictors of RIWG in stratified samples. Conclusions. Early childhood obesity intervention efforts may target the modifiable risk factors for RIWG starting prenatally.

Donuts on our daughters: Gender differences in food categories on children's apparel.

OBJECTIVE: Recent trends in children's fashion have featured food-graphics on children's apparel. Little attention has been paid to the food-graphic content of children's apparel. The objectives of this study were to describe and quantify food-graphics appearing on children's apparel, to examine characteristics of children's apparel items associated with the presence versus absence of food-graphics, and to examine gender differences in food-graphics. METHODS: A content analysis of food-graphics on children's apparel from major apparel retailer websites was performed. Images of food-graphic apparel were reliably coded for food-graphic categories. Multivariable analyses examined the association of apparel item characteristics with food-graphic presence. Bivariate analyses tested the association of presence or absence of each food category with gender of apparel item. RESULTS: Of the 3870 apparel items coded, 8.2% (318) had food-graphics. In multivariable analysis, food-graphics were more likely to be present on girls' (versus boys') apparel (RR = 1.73, 95% CI 1.34-2.12). Content analysis of food-graphic items revealed categories including "pastries", "frozen desserts", "pizza", "fast food", "fruit", and "love of food". Girls' (versus boys') food-graphic apparel was more likely to have categories of "pastries" (33% versus 12%), "frozen desserts" (20% versus 9%), and "fruit" (30% versus 11%) and less likely to have categories of "pizza" (9% versus 30%), and "fast food" (3% versus 23%). The "love of food" category did not differ by gender. All p-values ≤.01. CONCLUSIONS: Food-graphics on children's apparel are fairly common, especially on apparel marketed for girls. Children's apparel may represent a novel cultural influence on children's eating and food perceptions.
