Abstract: Objective To study the situation of common gastrointestinal problems among 1~12 months infants in 15 Chinese cities,and to provide theoretical basis for early-stage prevention and intervention against infantile gastrointestinal common problems. Methods Totally fifteen cities were chosen according to China′s geological and demographic distribution. Randomly cluster sampling method was used to choose a community within each city as the sample region. Infants aged 1~2 months were enrolled and their caregivers were interviewed by face-to-face questionnaire survey. Results Of 4 202 recruited infants,1 411 infants (33.6%) had common gastrointestinal problems. The prevalence of regurgitation,excessive crying,loose stools,dyschezia or dry stools were 14.4%,1.7%,23.0% and 8.5%,respectively. The prevalence of single regurgitation,excessive crying,loose stools,dyschezia or dry stools in infants with common gastrointestinal problems were 8.9%,0.7%,10.3% and 7.9%,respectively. Among complicated symptoms,the one with the highest rate was regurgitation and loose stools (4.3%);The prevalence rate peaked among infants aged 1~6 months,and the prevalence rate of regurgitation,excessive crying and loose stools dropped sharply with the age increased (P<0.05) while the prevalence rate of dyschezia or dry stools increased(P<0.05). Conclusions Gastrointestinal common problems in Chinese infants is increasingly prevalent. It is suggested to give related health education on gastrointestinal problems and feeding,thereby signifying the importance of primary prevention and intervention for infants and caregivers.
