Infant formula feeding practices in a prospective population based study.

Area of Science:

• Pediatrics
• Infant Nutrition
• Public Health

Background:

• Standard whey-based infant formula is recommended for formula-fed infants.
• Limited data exists on parental adherence to whey-based formula for the first year.
• Parental motivations for infant formula selection are largely unknown.

Purpose of the Study:

• To describe the use of whey-based and non whey-based infant formula by parents in the first year of life.
• To identify reasons for parental formula switching.

Main Methods:

• Utilized data from the Cork BASELINE Birth Cohort Study.
• Examined infant feeding at 2, 6, and 12 months.
• Employed descriptive analysis and logistic regression.

Main Results:

• Whey-based formula use decreased significantly over the first year (62.4% at 2 months to 12.8% at 12 months).
• No consistent parental or infant factors influenced whey-based formula use.
• Perceived infant hunger was the primary reason for switching to non whey-based formula.

Conclusions:

• Most infants start on whey-based formula but transition to non whey-based formula before 12 months.
• Parental perception of satiety, not professional advice, is the main driver for formula changes.
• Further research is needed on the growth effects of different infant formulas.
