Insights
Breastfeeding infants is linked to lower consumption of juice and sugar-sweetened beverages (SSBs) in the first year of life. This supports early intervention for healthier beverage habits.
Area of Science:
- Pediatric Nutrition
- Public Health
- Maternal and Child Health
Background:
- Breastfeeding in infancy is associated with healthier beverage choices later in childhood.
- Limited data exists on the relationship between breastfeeding and beverage consumption during infancy.
Purpose of the Study:
- To investigate the association between breastfeeding and the consumption of 100% juice and sugar-sweetened beverages (SSBs) during the first year of life.
- To examine early-life beverage consumption patterns in a birth cohort in the Southeastern United States.
Main Methods:
- Longitudinal study of 666 infants in a birth cohort (2013-2018).
- Multivariable adjusted models estimated monthly rates of 100% juice and SSB consumption.
- Comparison between exclusively/partially breastfed infants and non-breastfed infants.
Main Results:
- By 12 months, infants consumed juice 9.1 times/week and SSBs 3.6 times/week.
- Breastfed infants showed significantly lower incidence rates of weekly juice consumption (38% lower) and SSB consumption (57% lower) compared to non-breastfed infants.
- Key demographic factors included median maternal age of 26.5 years, 71% identifying as Black/African-American, and 61% with household incomes <$20,000/year.
Conclusions:
- Consumption of obesogenic beverages may commence before one year of age.
- Focusing on the earliest beverage consumption is crucial for understanding early-life dietary health correlates.
- Findings highlight the protective role of breastfeeding against less healthy beverage intake in infancy.
Background And Objectives:
Breastfeeding during infancy is associated with healthier beverage consumption later in childhood, but little is known about this relation during infancy. This was a longitudinal study of breastfeeding and less healthy beverage consumption during the first year of life, in a birth cohort study conducted 2013-2018 in the Southeastern United States (n = 666).
Methods:
We estimated monthly rates of 100% juice and sugar-sweetened beverage (SSB) consumption comparing infants who were exclusively or partially breastfed, versus those who were not, in multivariable adjusted models.
Results:
Mothers had a median age of 26.5 years, 71% identified as Black/African-American, and 61% reported household incomes <$20 000/year. The prevalence of any breastfeeding during the first month was 78.2% and 18.7% at month 12. By age 12 months, infants consumed juice a mean (SD) 9.1 (10.1) times per week and SSBs 3.6 (9.5) times per week. Breastfed infants had a 38% lower incidence rate of weekly juice consumption (95% CI 52%, 15%, p = 0.003) and a 57% lower incidence rate of weekly SSB consumption (95% CI 76%, 22%, p = 0.006), compared with infants who were not breastfed.
Conclusions:
Research on early-life correlates of dietary health should focus on the earliest beverages, given evidence that consumption of obesogenic beverages may begin prior to age 1 year.
