Prolonged bottle use and its association with iron deficiency anemia and overweight: a preliminary study
Insights
Prolonged bottle feeding in young children is common and linked to obesity and iron deficiency anemia (IDA). Limiting bottle use may improve child health outcomes.
Area of Science:
- Pediatric Nutrition
- Public Health
- Childhood Obesity
Background:
- Prolonged bottle feeding is a prevalent practice in young children.
- Obesity and iron deficiency anemia (IDA) are significant public health concerns in early childhood.
Purpose of the Study:
- To investigate the prevalence of prolonged bottle feeding.
- To examine the association between bottle feeding and body mass index (BMI) and IDA in WIC-enrolled children.
Main Methods:
- Cross-sectional survey study conducted at three WIC sites in the Bronx, NY.
- 95 caregivers of children aged 18-56 months completed questionnaires.
- Prevalence of prolonged bottle feeding, overweight/obesity (BMI), and IDA were assessed.
Main Results:
- Two-thirds (63%) of children received daily bottles with milk or sweet liquids.
- Bottle use was significantly associated with obesity (p<0.0005) and IDA.
- No significant association was found between bottle use and being overweight (p<0.06).
Conclusions:
- Prolonged bottle feeding is common among WIC-enrolled children.
- Bottle feeding is a significant risk factor for childhood obesity and IDA.
- Interventions targeting bottle feeding practices may help reduce obesity and IDA prevalence.
Abstract:
To determine the prevalence of prolonged bottle feeding practices in young children, and its association with body mass index (BMI) and iron deficiency anemia (IDA), we conducted a cross-sectional survey study at 3 Bronx, NY, WIC sites. Caregivers of 95 predominantly Hispanic and African-American WIC-enrolled children aged 18-56 months presenting for recertification completed questionnaires. Half were overweight (>85th% BMI) and 36% were obese (>95th% BMI); 21% met CDC criteria for anemia. Two thirds (63%) received daily bottles of milk or sweet liquids. Daily bottle use ranged from 3 to 10 (mean=3.3, median=3). Bottle use was significantly associated with obesity (>95th% BMI, p<0.0005), not significant with overweight (>85th% BMI, p<0.06) and statistically significant with IDA.
