Abstrakt:	Objectives: The goals of this study were to determine the prevalence of H. pylori antibodies in children, to establish the relationship between child and mother serostatus, and to identify potential risk factors for contamination. Material and Methods: A cross-sectional study was conducted over a 3-month period. All children between 6 months and 5 years of age examined in the Pediatrics Department of the University Hospital Center in Yopougon, Côte d'Ivoire were included after obtaining informed consent from their mothers. Testing for H. pylori antibodies using Pylorix (Acon) was performed in both children and mothers. Based on test results, children were divided into two groups, i.e. case group with H. pylori antibodies and control group without H. pylori antibodies. Case and control groups were compared according to the H. pylori status of their mother and several potential lifestyle and environmental factors. Results: A total of 101 children and 101 mothers were included. The prevalence of H. pylori antibodies was 40.6% in mothers and 24.8% in children. The mean age of children (53% male) was 22.8 +/- 15.6 months (median, 18 months). The mean age of the mothers was 29.6 +/- 5.5 years (range, 19 to 46 years; median, 29 years). Most mothers, i.e., 78.2%, lived in two-parent households but 19% lived in single-parent settings (community or shacks). The number of persons living in the same house ranged from 2 to 20 people (mean, 7.2 +/- 3.8; median, 6 people). Mean monthly household income was 226,188 +/- 161,425 FCFA (range: 30,000 - 750,000 FCFA). In the case group, 80% of children had mothers infected with H. pylori. In the control group, 73.7% of children had non-infected mothers (OR = 11.2, p < 0.001). Median income was less than 150 000 FCA in 76% of families with seropositive children in comparison to 46.1% of families with seronegative children (p = 0.009). Conclusion: This study confirms the early occurrence of H. pylori infection in children. Findings also showed that poor socio-economic condition was a risk factor for infection but the greatest risk factor was living with a mother infected with H. pylori.
