Associations between early introduction to complementary foods, subsequent cereal-added bottle feeding and daily macronutrient intake among infants.

Introducing complementary foods early during infancy has been associated with an increased risk of overweight later in life, but the pathway is an understudied topic. Hence the study was conducted with low-income and primarily minority mother-infant dyads to: 1) understand how the introduction of complementary foods prior to 4 months was associated with socio-demographic characteristics and food security status; 2) determine the association between early introduction to complementary foods and breastfeeding and adding cereal into the bottle in later infancy (i.e., at 6 and 9 months), and; 3) examine how adding infant cereal into the bottle was related to daily calorie and macronutrient intake in infancy. We conducted interviews with mothers (n = 201) at 4 months of age and 24-h feeding recalls at age 6 and 9 months. Results indicated that 29% of the infants were fed complementary foods before 4 months of age. Introducing complementary foods early was negatively associated with breastfeeding and positively associated with adding cereal into the bottle at 6-months. This practice was more common among those who experienced marginal to very low levels of food security. Comparing by race/ethnicity, Latinx mothers were significantly less likely to introduce solids early. After controlling for sex, infants fed cereal in the bottle were consuming significantly more calories compared to their counterparts. Specifically, adding cereal into the bottle resulted in approximately 10% additional daily calorie intake among infants. Understanding how these feeding practices affect appetite development and weight status during infancy is warranted.

Food and housing insecurity: do they affect the continuation of breastfeeding at four months of age?

To examine the relationship between food and housing insecurity and the continuation of breastfeeding, interviews were conducted with 203 birthing parents in English or Spanish. The study was conducted between August 2019 and March 2021 in the southeastern U.S. The breastfeeding rate among participants was 52%. Multivariate analysis indicated that birthing parents experiencing housing insecurity were less likely to be breastfeeding at 4 months of infant's age (p = 0.019). Future research is warranted to understand how housing insecurity might contribute to the discontinuation of breastfeeding through stress, poor rent affordability and the lack of clean and safe environments.
