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%).
