Insights
Prolonged bottle feeding beyond age one in children is linked to increased milk and calcium intake. This study found no evidence of negative impacts on total calories, iron, or obesity risk factors.
Area of Science:
- Pediatric Nutrition
- Childhood Dietary Habits
- Public Health
Background:
- Limited data exists on the nutritional consequences of prolonged bottle feeding beyond one year of age.
- Understanding dietary patterns in early childhood is crucial for long-term health outcomes.
Purpose of the Study:
- To assess the impact of prolonged bottle feeding on caloric intake and dietary composition in children at 3.5 years of age.
- To provide evidence-based information for pediatricians and parents regarding bottle-feeding practices.
Main Methods:
- A 24-hour dietary assessment was conducted on 165 children followed from infancy.
- Children were categorized into bottle-fed and weaned groups at 3.5 years old.
- Nutritional intake, including milk, calories, macronutrients, and iron, was analyzed.
Main Results:
- Bottle-fed children consumed significantly more milk and had higher daily calcium intake.
- Bottle-fed children received fewer calories from carbohydrates and a greater percentage of calories from protein.
- No significant differences were observed in total caloric intake, iron intake, juice volume, or calories from fat.
Conclusions:
- Continuing bottle feeding beyond age one is associated with increased milk and calcium consumption.
- Prolonged bottle feeding was not linked to decreased iron intake or increased risk factors for adiposity in this cohort.
- Findings can inform pediatricians advising parents on appropriate feeding practices.
Abstract:
Little is known about the consequences to children of bottle feeding prolonged beyond age 1 year on caloric intake and overall dietary composition. To obtain these data, 165 children, followed up from infancy, were assessed in these respects for a 24-hour period at age 3 1/2 years. Bottle-fed children (n = 14) consumed more milk than their weaned counterparts (p < 0.001), had a higher mean daily calcium intake (p < 0.05), received fewer calories from carbohydrates (p = 0.034), and received a greater percentage of calories from protein (p = 0.033). There were no significant differences between the groups in total caloric intake, total iron intake, total volume ofjuice, or calories from fat. Pediatricians questioned about the effects of continuing to offer children nutritive liquids from bottles as well as cups (versus offering cups alone) may inform parents that this feeding practice is associated with significantly greater milk consumption and daily calcium intake. However, this study could not find evidence that prolonged bottle feeding at age 3 1/2 years is associated with a significantly decreased total daily iron intake or an increased risk for factors associated with adiposity such as a greater daily calorie intake, a higher body mass index, or greater percentage of total calories derived from fat.
