Self-Efficacy in Children with Functional Constipation Is Associated with Treatment Success.

OBJECTIVES: To assess the relationship between self-efficacy, the belief that an individual can succeed at a goal, and short-term treatment outcome in children with functional constipation. STUDY DESIGN: Patients with functional constipation age 8-16 years completed the Self-Efficacy for Functional Constipation Questionnaire (SEFCQ), consisting of 14 statements about performing tasks needed for defecation. Patients completed SEFCQ before, immediately after, and 3 weeks after their clinic visit. Treatment success was defined as ≥3 bowel movements into the toilet and no fecal incontinence in the third week. RESULTS: 75% of patients had a successful outcome. Scores were higher in the group that was successful than in those that failed before, immediately after the visit, and 3 weeks later (P < .001). Self-efficacy improved at all time points in the group that was successful (P < .001). In the group that failed, scores improved immediately after clinic visit (P < .01) but were unchanged at follow-up (P > .05). CONCLUSIONS: Improved self-efficacy is associated with successful outcomes in children with functional constipation, thus, it may be beneficial to enhance self-efficacy for defecation during treatment.

Age of Onset of Functional Constipation.

In a review of 538 children with functional constipation, we analyzed ages of presentation and onset, symptom duration, and behavioral/developmental problems. We divided the subjects into quartiles (Q1-Q4) based on age of onset. Median onset age was 2.3 years. The oldest group had the shortest symptom duration before referral at 1.8 ±â€Š1.8 years (compared with Q3 to Q1, P = 0.039, P = 0.001, P < 0.001, respectively). Of the Q4 subjects, 22% had a behavioral/developmental problem (P < 0.001 compared with Q1-Q3). We conclude that most children develop functional constipation as infants and toddlers, but those with later onset are more likely to have behavioral/developmental issues and see a specialist sooner.

Prevalence of obesity in International Special Olympic athletes as determined by body mass index.

The heights and weights of 1,749 Special Olympics athlete volunteers participating in the Special Olympics Games in 1999 and 2001 were measured, and body mass index (BMI) was computed. Results indicated that athletes from the United States (US) under 18 years of age had a significantly (P<.001) higher prevalence of being overweight or at risk of being overweight compared with athletes from other countries. Similarly, adult athletes from the United States were at least 3.1 times more likely to be overweight or obese compared with their non-US counterparts. The risk of obesity in US Special Olympic athletes parallels the prevalence of obesity in the general US population. There is a clear need for further research, surveillance, and treatment of the risky health behaviors that contribute to the development of obesity in this group.

The seroprevalence of Helicobacter pylori in a referral population of children in the United States.

OBJECTIVES: The purpose of this study was to determine the prevalence of serum antibodies directed against Helicobacter pylori (H. pylori) in children referred to children's hospitals or medical centers throughout the United States. METHODS: This multisite cross-sectional prospective study involved 992 children from 12 states using a validated anti-H. pylori IgG enzyme immunoassay. The children were recruited into two groups: those without any GI complaints (non-GI referral, n = 619) and those who were referred for endoscopy because of abdominal pain (GI referral, n = 373). RESULTS: GI referral children had a higher rate of seropositivity (22.5%) than non-GI referral children (14.1%) from the same geographic regions. In both groups, older children were more likely to be seropositive for H. pylori, as were nonwhite children and those with lower socioeconomic status. H. pylori seropositivity rates were higher in GI referral children with four or more household members (relative risk [RR] = 1.47; CI 1.01-2.14). Multivariate analysis controlling for age, ethnicity, and household income, showed that presence of GI symptoms were associated with a nearly 2-fold risk for H. pylori seropositivity (odds ratio = 1.77, CI 1.27-2.47). Epigastric pain (RR = 2.21; CI = 1.33-3.66) and having three or more episodes of abdominal pain in the last 3 months (RR = 0.59, CI = 0.35-0.99) were the only specific symptoms significantly associated with H. pylori seropositivity. CONCLUSIONS: The H. pylori seropositivity rate of GI referral children with symptoms of abdominal pain was significantly higher. H. pylori infection in early childhood was found to be associated primarily with the child's household size and socioeconomic status.
