Insights
Synbiotic-enriched infant formula reduced infectious diseases and improved weight gain compared to standard formula. This suggests synbiotics may benefit infant health and growth.
Area of Science:
- Pediatrics
- Microbiology
- Nutrition Science
Background:
- Infectious diseases pose a significant public health challenge for infants.
- Synbiotic-enriched formulas aim to replicate the protective effects of human milk against infections.
- Infant feeding practices, particularly the transition to follow-on formulas, are critical for health outcomes.
Purpose of the Study:
- To evaluate the impact of synbiotic-enriched formula (EF) versus standard formula (SF) on infectious disease incidence in infants.
- To assess the effects of EF on infant growth parameters.
Main Methods:
- An observational study involving 771 healthy infants switching to follow-on formula.
- Data collection included family characteristics, medical history, growth, and infectious disease details (symptoms, severity, treatment).
- Outcomes were compared between EF and SF groups after adjusting for baseline characteristics.
Main Results:
- Infants fed EF experienced fewer overall infectious diseases (31.0%) compared to SF (40.6%).
- EF significantly reduced gastrointestinal infections (EF: 3.5%; SF: 6.8%).
- Higher weight gain was observed in infants fed EF (18.3 g/day) versus SF (16.9 g/day).
Conclusions:
- Synbiotic supplementation in infant formula may decrease the incidence of infectious diseases.
- Synbiotics appear to promote better growth in infants.
- Further research is required to establish optimal synbiotic formulations and dosages for infant formulas.
Aim:
Infectious diseases in infants are a major public health issue. Synbiotic-enriched formulas (EF) are intended to mimic the beneficial effects of human milk on infectious diseases. We performed an observational study in infants switching to follow-on formula to determine the effects of synbiotic-enriched formula compared to standard formula (SF).
Methods:
We recorded family characteristics, medical history and growth data, as well as the symptoms, severity and treatment of infectious diseases. Main outcome measures were compared after adjustments for baseline characteristics.
Results:
Between January and June 2007, 771 healthy infants were included in the study; 35.4% experienced at least one infectious disease during the 3-month study period. The most common were upper respiratory tract (24.1%), otitis (6.6%) and gastrointestinal infectious diseases (5.0%). Infants fed synbiotic-enriched formula had fewer infectious diseases overall (EF: 31.0%; SF: 40.6%; p = 0.005) and significantly fewer gastrointestinal infectious diseases (EF: 3.5%; SF: 6.8%; p = 0.03). During follow-up, weight gain was significantly higher (p = 0.0467) in infants fed synbiotic-enriched formula (18.3 ± 8.7 g/day) versus SF (16.9 ± 7.5 g/day).
Conclusions:
Supplementation with synbiotics may have beneficial effects on the incidence of infectious disease and growth in infants. Further studies are needed determine optimal doses and composition of synbiotics in infant formula.

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
