Estimating infants' and toddlers' inhalation exposure to fragrance ingredients in baby personal care products.

ABSTRACT: Fragrance ingredients are commonly added to many personal care products to provide a pleasant scent, including those intended for babies. While fragrance chemicals have a long history of safe use, at sufficiently high concentrations some may act as respiratory irritants or sensitizers. Little data have been reported on the inhalation exposures to fragrance compounds to infants and toddlers during bathing and lotion applications. This study demonstrates an in vitro method for measuring breathing zone air concentrations of fragrances from bath products and lotions. It employed simulated infant bathing and lotion application events and a robot to mimic a toddler's movement within a bathroom setting. The air concentrations in an infant's breathing zone were between <1 and 5 ?g/m3 for each of seven common fragrance ingredients, while that in the breathing zone of toddlers in the bathroom was ? 1?g/m3. The air concentrations from the bathing additive were linearly related to their Henry's law constants and from the lotion inversely related to their octanol-air coefficients. The proposed approach can help refine risk estimates from inhalation exposure to fragrances used in baby products and guide future risk assessments of new products' safety for their use in baby bath products.

Project description:BackgroundThe prevalence of obesity and type 2 diabetes continues to increase. These conditions disproportionately affect minorities and are associated with poor nutrition early in life. Current food-consumption patterns can inform pending dietary guidelines for infants and toddlers.ObjectiveThe aim of this study was to describe infant feeding, complementary feeding, and food and beverage consumption patterns of 0- to 23.9-mo-olds in the general population.MethodsThe Feeding Infants and Toddlers Study 2016 is a cross-sectional survey of caregivers of children aged <4 y. Dietary data were collected from a national random sample by using a 24-h dietary recall (n = 3235). The percentage of children consuming foods from >400 food groups was calculated. Differences in the percentage consuming between Hispanic, non-Hispanic white, and non-Hispanic black children aged 0-23.9 mo were evaluated with the use of ORs and 95% CIs.ResultsEighty-three percent of 0- to 23.9-mo-olds (n = 2635) were ever breastfed, 34% of 0- to 3.9-mo-olds (n = 305) and 15% of 4- to 5.9-mo-olds (n = 295) were exclusively breastfed, and 24% of 12- to 14.9-mo-olds (n = 412) consumed breast milk on the day of the recall. Complementary foods were more likely to be introduced before 4 mo in formula-fed infants (27%) than in infants who did not consume formula (5%). Half of 4- to 5.9-mo-olds consumed iron-fortified infant cereal, but few consumed iron-rich meats. Among toddlers (12-23.9 mo; n = 1133), >20% consumed no servings of fruit or vegetables on the day of the recall, approximately half consumed 100% fruit juice, and one-quarter to one-third consumed a sugar-sweetened beverage (SSB).ConclusionsBreastfeeding initiation and duration have improved, but exclusivity remains low. Low consumption of iron-rich foods, fruit, and vegetables and lack of variety in vegetable consumption are problems. Efforts to reduce the consumption of SSBs and 100% fruit juice are warranted in early childhood.

Project description:IntroductionUnderstanding which foods are introduced in the diet and when provides valuable information on complementary feeding. Fortified baby rice cereal is the most common first solid food given to infants, often followed by other baby cereals. The objective of this study was to examine food patterns among infants and toddlers consuming rice or non-rice baby cereals versus non-consumers.MethodsNHANES 2001-2014 data were used to assess dietary intake, nutrient adequacy, and food specific patterns of infants and toddlers. Groups were: baby cereal non-consumers (n = 3,910), non-rice baby cereal consumers (n = 711), and rice baby cereal consumers (n = 966). Those consuming both non-rice cereal and rice cereal were included in the rice cereal group (n = 9, 48, 61, and 10 for those 0-3, 4-6, 7-11, and 12-23 mos, respectively). Least-square means ± SEs were determined for nutrient intake and food group consumption by using covariate controlled regression analyses (p < 0.01).ResultsBaby cereal consumer groups, compared to non-consumers, had higher intakes of carbohydrates, iron, calcium, magnesium, zinc, and vitamin E, with lower percentage having intakes below the Estimated Average Requirement for iron, calcium, and vitamin E. Infants 0-3 mos and 4-6 mos in both baby cereal consumption groups consumed other solid foods, including baby foods and beverages, sweetened beverages, coffee and tea, 100% juice, vegetables (excluding potatoes), fruit, sugars, milk and yogurt, and mixed dishes. The baby cereal consumers and non-consumers groups had intakes aligned with the "American diet". Baby cereal non-consumers had a significantly higher percentage of exclusively breast fed at ages 0-3 mos and a lower percentage formula fed.ConclusionThis study provides detailed information on the introduction of baby cereals which was associated with better nutrient intakes and other complementary foods and intakes of nutrients that require special attention during early life. Further, cow's milk products and solid foods were introduced prior to the American Academy of Pediatrics' age recommendations.
