Table 3. Adjusted analyses for associations between geohelminth parasite species and parasite burdens in mothers and in children up to and at 5 years of age, and wheeze and allergen skin test (SPT) reactivity to any allergen at 8 years and asthma between 5 and 8 years
SPT – allergen skin prick test reactivity to any of 9 allergens. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression and adjusted for maternal allergy and ethnicity, area of residence, sex, birth order, contact with large farm animals, geohelminths in the child to 5 years (for maternal geohelminths), maternal geohelminths (for childhood geohelminths), and presence of other species of geohelminth parasite. Infection intensity categories are: A. lumbricoides , light (<5,000 epg), moderate/heavy (>5,000 epg); T. trichuira , light (<1000 epg), moderate/heavy (>1,000 epg). P<0.05 are shown in bold. Denominators for geohelminth prevalence versus intensity results differ because it was not possible to do Kato-Katz examinations on all samples where sample volume was insufficient. P<0.05 are shown in bold.
