Insights
Cesarean section delivery significantly impacts infant gut microbiota development, potentially leading to long-term health issues. Interventions like probiotics and breastfeeding may help restore healthy neonatal gut microbiota.
Area of Science:
- Microbiology
- Neonatal Health
- Immunology
Background:
- The neonatal gut microbiota is crucial for immune development and overall health.
- Delivery mode is a key factor influencing early gut microbial colonization.
- Rising cesarean section rates pose a global public health challenge.
Purpose of the Study:
- To analyze the impact of vaginal delivery versus cesarean section on neonatal gut microbiota establishment.
- To explore potential long-term health consequences of altered neonatal gut microbiota.
- To review interventions for mitigating cesarean section-associated gut microbiota dysbiosis.
Main Methods:
- Comprehensive literature review of studies on neonatal gut microbiota.
- Analysis of factors influencing microbial colonization, focusing on delivery mode.
- Evaluation of interventions aimed at correcting gut microbiota defects.
Main Results:
- Cesarean section alters the composition and diversity of the neonatal gut microbiota compared to vaginal delivery.
- These alterations may be linked to increased risk of certain diseases later in life.
- Breastfeeding, probiotics, prebiotics, vaginal seeding, and fecal microbiota transplantation show promise in addressing these alterations.
Conclusions:
- Delivery mode profoundly influences neonatal gut microbiota development with potential lifelong implications.
- Targeted interventions can help ameliorate negative effects of cesarean section on infant gut microbiota.
- Further research is needed to optimize strategies for promoting healthy microbial colonization in infants born via cesarean section.
Abstract:
Recent research has emphasized the critical importance of establishing the neonatal gut microbiota for overall health and immune system development, prompting deeper studies about the early formation of neonatal gut microbiota and its influencing factors. Various factors, including maternal and environmental factors, affect the early formation of neonatal gut microbiota, in which delivery mode has been considered as one of the most crucial influencing factors. In recent years, the increasing trend of cesarean section during childbirth has become a serious challenge for global public health. This review thoroughly analyzes the effects of vaginal delivery and cesarean section on the establishment of neonatal gut microbiota and the potential long-term impacts. In addition, we analyze and discuss interventions such as probiotics, prebiotics, vaginal seeding, fecal microbiota transplantation, and breastfeeding to address the colonization defects of the neonatal gut microbiota caused by cesarean section, aiming to provide theoretical basis for the prevention and treatment of colonization defects and related diseases in infants caused by cesarean section in clinical practice and to provide a theoretical foundation for optimizing the development of neonatal gut microbiota.
