Association between Helicobacter pylori infection and growth outcomes in children: A meta-analysis

Abstract

Background: Multiple studies have reported the association between Helicobacter pylori (H. pylori) infection and children's growth. The results of these studies are controversial. Our meta-analysis aimed to evaluate the association between H. pylori infection and growth outcomes in children.

Methods: We searched PubMed, Embase, Web of Science, and Cochrane Library, as well as two Chinese databases, Wanfang, and CNKI from inception to September 2019. Odds ratios (ORs) and standardized mean differences (SMDs) with their 95% confidence interval (95% CI) were selected as the effect size. We assessed pooled data using a random-effects model. Subgroup and sensitivity analyses were conducted.

Results: In total, 29 studies provided data from 9384 subjects. The meta-analysis results indicated a significant association of H. pylori infection with ponderal growth disorders (OR: 2.47; 95% CI: 1.13, 5.37; p = 0.02) and linear growth disorders (OR =1.76; 95% CI: 1.15, 2.69, p = 0.01). H. pylori infection has an adverse impact on children's height-for-age Z (HAZ) scores (SMD = -0.41; 95% CI: -0.69, -0.13; p < 0.01). Pooling SMDs by other outcomes (height, weight, BMI, weight-for-age and BMI-for-age Z scores, weight-for-age percentile scores, and linear and ponderal growth velocity with/without infection and eradication/non-eradication) all indicated no significant association.

Conclusion: The current evidence supports the hypothesis that H. pylori infection is associated with growth outcomes in children, mainly HAZ scores. Clinicians might consider H. pylori infection in investigating linear growth disorders in children.
