RESUMO
Epidemiological studies have shown that the prevalence of Helicobacter pylori infection in a community and occupational health are closely related to lifestyle and socio-economic status. There is little information on H. pylori profile in industrial workers in the literature. The aim of this study was to investigate the prevalence rate of H. pylori profiles among low socio-economic workers in the United Arab Emirates (UAE). This study was undertaken by determining IgG H. pylori antibody profiles among industrial exposed and referent workers, sera. Presence of anti-H. pylori antibodies in the frozen stored sera was determined by ELISA. Also, data on dietary and lifestyle were obtained. The result was considered positive if IgG anti-H. pylori antibody titers was > 300. People with seropositive levels of IgG antibodies to H. pylori were assumed to be infected with H. pylori. Most of the industrial workers lived in less modern accommodation, were less educated, ate their vegetable products unwashed and did not have drinking water facilities, when compared to referents. H. pylori serology by IgG was positive in 167 industrial workers (78.4%) and 137 in referent workers (64.3%) respectively, (p < 0.002). The sensitivity and specificity of the IgG serology assay were 94.5%, and 97.2% respectively. There was statistically significant difference between the exposed industrial and non-exposed control groups in respect of their H. pylori profiles.
