Insights
Many infants in Brazil are not breastfed exclusively, with improper formula dilution and early introduction of solids. This raises concerns about nutrient intake and future chronic disease risk in young children.
Area of Science:
- Pediatrics
- Nutrition Science
- Public Health
Background:
- Infant feeding practices significantly impact child health and development.
- Understanding current dietary patterns is crucial for identifying potential health risks.
Purpose of the Study:
- To evaluate the feeding habits and nutritional consumption of healthy infants in Brazil.
- To identify inappropriate infant feeding practices and their potential long-term consequences.
Main Methods:
- A prospective study analyzed the 7-day food records of 179 infants (4-12 months) in three Brazilian municipalities.
- Infants were not exclusively breastfed; data was collected after nutritionist guidance.
- Dietary intake was calculated using the NutWin computer program.
Main Results:
- Over half of infants (50.3%) were not exclusively breastfed, with many receiving whole cow's milk.
- Infant formula dilution was incorrect in a majority of cases (76.2% and 65.3% for infants < and > 6 months).
- Complementary feeding and family diet introduction occurred early (median 4 and 5.5 months); significant micronutrient deficiencies (zinc, iron) were observed in older infants.
Conclusions:
- High prevalence of inappropriate feeding practices and inadequate dietary intake in Brazilian infants.
- These suboptimal practices may increase the risk of chronic diseases later in life.
Objective:
To assess feeding practices and dietary intake of healthy infants in three Brazilian municipalities.
Methods:
By means of a prospective study, we analyzed the food record of 7 consecutive days of an intentional sample (quota and weighted sampling) of 179 healthy infants, aged between 4 and 12 months, from the municipalities of Curitiba, São Paulo, and Recife, Brazil, who were not being exclusively breastfed. Mothers received oral and written information provided by a nutritionist with the purpose of standardizing the feeding data. The computer program NutWin was used to calculate the dietary intake.
Results:
The median of the infants' age was 6.8 months (4.0-12.6 months). We found that 50.3% of the infants were no longer being exclusively breastfed. Of these, 12.0 and 6.7% among the infants younger and older than 6 months, respectively, were fed with infant formulae instead of breast milk. Therefore, most infants received whole cow's milk. Infant formula dilution was correct in only 23.8 and 34.7% of the infants younger and older than 6 months old, respectively. With regards to complementary feeding, we found that the median age was 4 months for its introduction and 5.5 months for the introduction of family diet. There was high quantitative inappropriateness of micronutrient intake for infants between 6 and 12 months old who were not exclusively breastfed, mainly in terms of zinc (75%) and iron (45%).
Conclusion:
The present study showed a high frequency of inappropriate feeding practices and dietary intake in very young infants. These practices may lead to an increased risk of development of chronic diseases in the future.
