- Brief Summary
The study is a before-after trial to evaluate whether the study formula containing moderately hydrolyzed protein and low lactose will be able to improve mild gastrointestinal disorders (MGDs) in infants. The study plans to recruit 90 infants between 7 days and 6 months old in Huantai Maternal and Child Health Care Hospital in Shandong Province and intervene for 14 consecutive days. On Day 0 (the time of enrolling group, but the intervention which infants recruited are asked to drink study formula begins on Day 1), Day 7, Day 14, Infant Gastrointestinal Symptoms Questionnaire-13 (IGSQ-13) is used to collect infants gastrointestinal comfort, related behaviors and other information.
- Detailed Description
Mild gastrointestinal disorders in infants belong to the category of functional gastrointestinal disorders. It refers that the infants fed with formula have mild digestive dysfunction that can not be explained by organic lesions or biochemical abnormalities, mainly including intestinal colic, spitting milk, diarrhea, constipation, etc. Mild gastrointestinal disorders are common in infants aged 0 to 1 year old. A study across 15 cities in China on the prevalence of common gastrointestinal disorders in infants shows that about 1/3 of the infants have one or more types of gastrointestinal disorders, among of which diarrhea and spitting milk are most common, and most of them occur within the age of 6 months. To solve this problem, a special kind of formulas for infants containing moderately hydrolyzed protein and low lactose has been developed, and our study formula is one of them. The study formula has been already marketed in China and passed the test hosted by the comprehensive testing center of the Chinese academy of inspection and quarantine, but whether it can significantly improve the mild gastrointestinal disorders in Chinese infants remains to be evaluated.
The purpose of the study is to evaluate whether the study formula containing moderately hydrolyzed protein and low lactose will be able to improve mild gastrointestinal disorders (MGDs) in infants. After informed consent, 90 infants between 7 days and 6 months old with mild gastrointestinal disorders are included and asked to drink the study formula for 14 consecutive days as intervention. On Day 0 (the time of enrolling group, but the intervention begins on Day 1), Day 7, Day 14, the information on gastrointestinal comfort and related behaviors is collected through the Infant Gastrointestinal Symptoms Questionnaire-13 (IGSQ-13). Information on feeding, family background, anthropometric measurements and defecation is also collected. The primary endpoint of this study is gastrointestinal comfort calculated by IGSQ-13. The secondary endpoints include crying frequency, spitting milk frequency, flatulence frequency, stool frequency and consistency score, formula acceptability and satisfaction, adverse event, etc.

Parents (caregivers) are asked to recall specific symptoms experienced in the past week. Possible index scores range from 13 to 65; higher scores indicate higher GI burden, while lower scores indicate less GI burden.
- Secondary Outcome Measures
Name Time Method Crying frequency On Day 0, Day 7 and Day 14 Collected by Infant Gastrointestinal Symptoms Questionnaire-13 (IGSQ-13)
Formula acceptability and satisfaction On Day 14 Collected by a structured questionnaire，which is designed for this study specially, including 5 questions, and will be analyzed separately for each question (no total score used).
Spitting milk frequency On Day 0, Day 7 and Day 14 Collected by Infant Gastrointestinal Symptoms Questionnaire-13 (IGSQ-13)
Stool frequency and consistency On Day 1, Day 2 and Day 3 Collecting infants stool photos
