Table 1. Frequencies of maternal and childhood geohelminth infections to 5 years of age and potential confounders and associations with 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) for univariable associations were estimated using logistic regression. P<0.05 are shown in bold. Ethnicity ‘other’ represents: 1,417 Mestizo/8 Indigenous. Numbers of missing values (brackets) were: maternal allergy (14) and pneumonia during first 13 months (85). §Socioeconomic status (SES) represents tertiles of z scores obtained using a factor analysis with 1 representing the lowest and 3 the highest SES. ¶ Household overcrowding is defined as the number of people living in the household per sleeping room. ‡ Any of cows, pigs, mules, donkeys, and horses. Other helminths: mother (S. stercoralis , 4.0%;Hymenolepis spp., 0.5%); child (hookworm, 1.1%; S. stercoralis , 1.5%; Hymenolepis spp., 4.2%).
