Dietary patterns in infancy are associated with child diet and weight outcomes at 6 years

Area of Science:

• Pediatric Nutrition
• Childhood Obesity Research
• Dietary Pattern Analysis

Background:

• Infant feeding practices significantly influence long-term health outcomes.
• Understanding early dietary patterns is crucial for preventing childhood obesity.
• Previous research identified distinct infant dietary patterns based on milk and solid food intake.

Purpose of the Study:

• To determine if infant dietary patterns at 9 months of age are associated with children's diet and weight status at 6 years.
• To investigate the predictive value of early-life food consumption on later childhood eating behaviors and body mass index (BMI).

Main Methods:

• Utilized data from the Infant Feeding Practices Study II and Year 6 Follow-Up Studies.
• Employed latent class analysis to define five distinct infant dietary patterns.
• Controlled for confounding variables to assess the association between infant dietary patterns and 6-year-old outcomes.

Main Results:

• Infants with higher fruit and vegetable intake at 9 months showed similar consumption at 6 years.
• Dietary patterns high in energy-dense foods in infancy correlated with higher intake of these foods and increased overweight prevalence (43%) at 6 years.
• Formula-fed infants exhibited higher sugar-sweetened beverage intake and lower fruit/vegetable intake compared to breastfed infants at 6 years.

Conclusions:

• Early infant feeding choices, including milk type and solid food introduction, can predict later dietary habits and obesity risk.
• Exposure to energy-dense foods in infancy is associated with sustained consumption and elevated risk of overweight in childhood.
