Insights
Infants diagnosed with colic have a higher risk of developing irritable bowel syndrome (IBS) later in childhood. Early understanding of infantile colic may help reduce functional gastrointestinal disorders.
Area of Science:
- Gastroenterology
- Pediatrics
- Epidemiology
Background:
- The association between infantile colic and later development of irritable bowel syndrome (IBS) is not well understood.
- Infantile colic is a common condition affecting infants, but its long-term health implications require further investigation.
Purpose of the Study:
- To investigate the association between infantile colic and the subsequent risk of developing IBS in childhood.
- To evaluate the long-term risk of IBS in individuals with a history of infantile colic.
Main Methods:
- A large cohort study involving 917,707 children born in Korea between 2007-2008.
- Infantile colic was defined by ICD-10 codes R10.4 or R68.1 between 5 weeks and 4 months of age.
- Irritable bowel syndrome (IBS) was defined by ICD-10 code K58.X after 4 years of age. Propensity score inverse probability of treatment weighting (IPTW) was used to analyze the risk.
Main Results:
- The infantile colic group (359,842 children) showed a statistically significant increased risk of developing IBS in childhood (HR [95% CI], 1.12 [1.10–1.13]) compared to the control group (363,528 children).
- Subgroup analyses confirmed the significant association across various factors including feeding status, birth weight, sex, and economic status.
Conclusions:
- Infantile colic is a significant risk factor for developing IBS later in childhood.
- Understanding the pathogenesis of infantile colic may lead to strategies for reducing the prevalence and severity of functional gastrointestinal disorders throughout life.
Background/Aims:
Little is known about the association between infantile colic and the later onset of irritable bowel syndrome (IBS).
Methods:
This study examined all 917 707 children who were born in Korea between 2007 and 2008. Infantile colic was defined with 1 or more diagnoses of ICD-10 code R10.4 or R68.1 at the age of 5 weeks to 4 months, and infants with a diagnosis of infantile colic and without were allocated into the infantile colic group and the control group. IBS was defined as 2 or more diagnoses of ICD-10 code K58.X after 4 years of age. Each child was traced until 2017. The risk of IBS with infantile colic was evaluated using a Cox proportional hazards model with propensity score inverse probability of treatment weighting (IPTW).
Results:
After IPTW, 363 528 and 359 842 children were allocated to the control group and the infantile colic group, respectively. The infantile colic group had a higher risk of developing IBS in childhood (hazard ratio [95% CI], 1.12 [1.10 to 1.13]) than the control group. Moreover, the subgroup analyses according to the feeding status, birth weight, sex, or economic status, showed that the risk of IBS with former infantile colic remained statistically significant.
Conclusions:
Children with a diagnosis of infantile colic during the infant period had a significant risk of developing IBS after 4 years of age. Understanding the pathogenesis of infantile colic in the neonatal period may reduce the prevalence and severity of functional gastrointestinal disorders from childhood to adolescence to adulthood.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
