Does a vigorous feeding style influence early development of adiposity?

Area of Science:

• Pediatrics
• Human Physiology
• Developmental Biology

Background:

• Early adiposity in infants is a growing concern with potential long-term health implications.
• Understanding the factors that influence infant body composition is crucial for developing effective health strategies.
• Infant feeding behaviors are hypothesized to play a significant role in the development of early adiposity.

Purpose of the Study:

• To investigate the factors influencing the development of early adiposity in healthy infants from birth to 2 years of age.
• To examine the relationship between infant suckling behaviors, parental education, and adiposity measures.
• To identify specific feeding patterns associated with increased or decreased adiposity.

Main Methods:

• A prospective cohort study observed healthy infants from birth to 2 years.
• Infant suckling was measured in a laboratory setting during the first month of life.
• Multiple regression analyses were used to assess the influence of feeding behaviors and parental education on adiposity.

Main Results:

• Parental education and suckling interval between bursts explained 18% of triceps skinfold variance at 1 year.
• Lower parental education and shorter suckling interburst intervals were linked to increased adiposity.
• Suckling pressure and number of feeds per day explained 21% of skinfold thickness variance at 2 years.
• Fewer, larger feeds and higher suckling pressure were associated with greater adiposity.
• Breast-feeding showed a protective effect against early adiposity only up to 6 months.

Conclusions:

• Vigorous infant feeding styles, characterized by rapid, high-pressure sucking with specific durations and intervals, are associated with higher caloric intake and adiposity.
• The early emergence of these feeding styles suggests a potential genetic basis.
• Parental education and specific infant feeding behaviors are significant predictors of early adiposity development.
