Precipitants of constipation during early childhood.

BACKGROUND: Childhood constipation is a common problem, accounting for 3% of visits to pediatric clinics and 30% of visits to pediatric gastroenterologists. Estimates of the prevalence of childhood constipation vary from 0.3% to 28% with younger children being affected most often. We were unable to find any studies that specifically examine the causes of constipation in young children. Our objective of the study was to determine precipitants to constipation during early childhood. METHODS: Findings from 125 families visiting their primary care physician for the first time with a child aged between 2 and 7 years with the complaint of constipation were compared with findings from 95 children between 2 and 7 years without any history of constipation. Parents answered questions concerning family history, toilet training, and bowel habits. Parents of constipated children were asked to describe events that occurred during the 3 months before the onset of constipation and whether these events contributed to the child's constipation. RESULTS: The age and sex of children who did and did not suffer from constipation were comparable (P > .3). When compared with control children, constipated children were no more likely to have a parent (30% vs 40%, P = .14) or sibling (17% vs 14%, P = .54) with a history of constipation. Constipated children did not begin toilet training earlier than did control children (28 +/- 7 vs 27 +/- 6 months, P = .30). When compared with parents of control children, parents of constipated children reported more difficulties with toilet training (P < .001). Parents of constipated children indicated their children had more difficult and more painful defecation experiences than did parents of control children (P < .001), and constipated children were more likely to express worry about future painful defecation than were control children (P < .001). Parents of constipated children described a number of events that occurred before the onset of constipation; however, they did not consider many of the events important contributors to the constipation. Painful defecation was the event most often reported as causing the constipation. CONCLUSION: Painful defecation is the primary precipitant of constipation during early childhood. Parents should be counseled to be attentive to such experiences and taught to intervene quickly to lessen the risk that their child will develop persistent constipation or fecal soiling.

[Case-control study of risk factors associated with constipation. The FREI Study].

BACKGROUND: Children represent one of the patient groups most affected by constipation. Our objective was to identify and describe the risk factors associated with childhood constipation. PATIENTS AND METHODS: The study had a case-control, retrospective, open and multicenter design. Clinical data on possible risk factors were collected through an ad-hoc questionnaire. Two groups were studied: children with and without constipation. RESULTS: Nine hundred twenty-one children were recruited; of these, 898 (97.6%) were included in the statistical analysis. There were 408 (45.4%) children in the constipated group and 490 (54.5%) in the non-constipated group. Most of the children with constipation (53.6%) had a maternal history of constipation compared with 21.4% of children without constipation (p < 0.05). More than half (53.2%) of the constipated children reported a lack of regularity in their toilet habits while 64.9 % of the children without constipation went to the toilet regularly. Toilet training started slightly earlier (at 3 years) in children without constipation (93.2%) than in those with the disorder (83.8%) (p < 0.05). At school, 57.4% of the children with constipation never used the toilet compared with 26.8% of those without constipation (p < 0.05). A total of 73.4% of children with constipation drank less than four glasses of water per day compared with 47.1% of those without constipation (p < 0.05). Consumption of vegetables and legumes in the diet was significantly lower in children with constipation than in those without (p < 0.05). The risk factors linked to childhood constipation found in this study were a familial history of constipation, irregular toilet habits, low dietary fiber contents and no fruit intake. The main preventive factors against constipation were water and vegetable consumption and training on the use of the toilet at school. CONCLUSIONS: Daily toilet training and dietary changes are needed to prevent constipation among children and to achieve regular defecation. This preventive intervention should be reinforced at school.
