Insights
Most infants received adequate nutrition through breastfeeding and complementary feeding (CF). However, many delayed introducing fish, legumes, and eggs, while overconsuming meats, impacting optimal infant nutrition.
Area of Science:
- Pediatric Nutrition
- Infant Health
- Dietary Guidelines Compliance
Background:
- Adequate infant nutrition involves breastfeeding, infant formula, and complementary feeding (CF).
- Understanding protein intake from CF is crucial for healthy infant development.
Purpose of the Study:
- To assess compliance with protein intake recommendations from complementary feeding in healthy infants aged 7 to 24 months.
Main Methods:
- A questionnaire collected data on demographics, feeding practices, and CF protein intake in 85 healthy infants.
- Statistical analysis included Chi-square tests and one-way ANOVA using STATA v13.
Main Results:
- 84.7% of infants started CF at 6 months; however, only 37.6% met fish, 49.4% legume, and 45.8% egg incorporation recommendations.
- Older infants (13-24 months) consumed excessive meat (83%) and insufficient fish (83.2% below recommendations), with many never having tried fish.
- 62% of formula-fed infants on CF received adequate protein (≥ 1 g/kg/day) from formula.
Conclusions:
- While most infants initiated complementary feeding appropriately, significant delays occurred in introducing key protein sources like fish, legumes, and eggs.
- Dietary patterns in older infants showed excessive meat consumption and inadequate fish intake, deviating from recommended guidelines.
Introduction:
Adequate nutrition includes breastfeeding, infant formula, and the incorporation of complementary feeding (CF).
Objective:
To describe compliance with the recommendations for protein intake from CF in healthy infants between 7 and 24 months old.
Patients And Method:
Healthy infants from an outpatient center were studied. To collect the variables under study, we designed and applied a questionnaire. We obtained demographic data, breastfeeding, use of formula, and incorporation and compliance with protein intake data. The analysis of variables was carried out with STATA software version 13, and the Chi-square test and one-way ANOVA were applied.
Results:
85 infants were stu died, 54% were female, 68% of infants were exclusively breastfed until 6 months old, and 84.7% star ted complementary feeding at that age. 37.6% complied with the incorporation of fish, 49.4% with legumes, and 45.8% with egg. 52% of infants aged between 10 and 12 months and 83% of infants bet ween 13 and 24 months consumed more beef, chicken, or turkey. This data was associated with being the first child and older age, as well as egg consumption where infants older than 12 months ate more than recommended. We observed lower than recommended fish consumption in 78% of infants aged between 10 and 12 months and 83.2% of infants between 13 and 24 months, of which 35% and 2.7% had never eaten fish, respectively. 45 infants were fed only with formula and complementary feeding, 28 (62%) of them received ≥ 1 g/kg/day of protein from infant formula.
Conclusions:
Most infants were exclusively breastfed until 6 months old and incorporated complementary feeding at that age. Most infants incorporated legumes, eggs, and fish later than recommended, and there was excessive consumption of beef, chicken, or turkey and little consumption of fish, especially at older ages.
