Insights
Term and preterm infants show similar bowel movement frequency from week two to 24 months. Breastfed infants had more frequent stools than formula-fed infants in the initial weeks.
Area of Science:
- Neonatal care
- Pediatric gastroenterology
- Infant nutrition
Background:
- Prospective studies on infant feeding and bowel habits are needed.
- Understanding term vs. preterm infant development is crucial.
Purpose of the Study:
- To describe and compare feeding and bowel habits.
- To analyze data from birth to 24 months in term and preterm infants.
Main Methods:
- 199 infants (126 preterm) aged 25-42 weeks gestation were studied.
- Bowel diaries recorded at 1-2 weeks, 3, 6, 12, and 24 months.
- Exclusion criteria: GI surgery, neurological, metabolic, or congenital diseases.
Main Results:
- Feeding frequency decreased in both groups over time.
- Breastfed infants had more defecations than formula-fed infants in weeks 1-2.
- Term infants had higher defecation frequency than preterm infants only in week 1.
Conclusions:
- Defecation frequency is comparable between term and preterm infants from week 2 to 24 months.
- Early differences in defecation frequency were observed.
Background And Aim:
New prospective studies concerning feeding and bowel habits of term and preterm infants from birth to 24 months of life are needed. The aim of the present study was to describe and compare feeding and bowel habits between term- and preterm-born infants starting from birth up to the age of 24 months.
Patients And Methods:
Between August and November 2006 all of the infants admitted to an academic and nonacademic neonatal care unit with gestational age 25 to 42 weeks participated in the study. Bowel diaries were recorded 1 and 2 weeks, and 3, 6, 12, and 24 months after birth. Infants with gastrointestinal surgery, neurological diseases, metabolic diseases, or congenital abnormalities were excluded.
Results:
A total of 199 (126 preterm) infants were eligible; 153 gave consent for participation. Although feeding frequency was higher in the first 3 months in the preterm born, overall feeding frequency decreased between the first 3 follow-up periods (P < 0.001) in both groups. In the first and second week, breast-fed infants had 2.41 more episodes of defecation per week compared with the formula-fed infants (P = 0.017 and P = 0.021, respectively). Higher median (10th percentile-90th percentile) defecation frequency was only found in week 1 in the term compared with the preterm group (24 [9.4-31.6] versus 16 [6.5-31]; P = 0.002). The overall median defecation frequency was 16 (7-30) per week from birth up to the age of 24 months over the total group of participating infants.
Conclusions:
Term and preterm infants have a comparable defecation frequency from the second week of life up to the age of 24 months.
