A primary health-care intervention on pre- and postnatal risk factor behavior to prevent childhood allergy. The Prevention of Allergy among Children in Trondheim (PACT) study
Background: This study aimed to evaluate the impact of a primary prevention intervention program on risk
behavior for allergic diseases among children up to 2 years of age. The setting was in ordinary pre- and postnatal
primary health care in Trondheim, Norway.
Methods: The Prevention of Allergy among Children in Trondheim, Norway (PACT) study invited all pregnant
women and parents to children up to 2 years of age in the community to participate in a non-randomized,
controlled, multiple life-style intervention study. Interventional topics was increased dietary intake of cod liver oil
and oily fish for women during pregnancy and for infants during the first 2 years of life, reduced parental smoking
and reduced indoor dampness. A control cohort was established prior to the intervention cohort with âfollow up
as usualâ. Questionnaires were completed in pregnancy, 6 weeks after birth and at 1 and 2 years of age. Trends in
exposure and behavior are described.
Results: Intake of oily fish and cod liver oil increased statistically significantly among women and infants in the
intervention cohort compared to the control cohort. There was a low postnatal smoking prevalence in both
cohorts, with a trend towards a decreasing smoking prevalence in the control cohort. There was no change in
indoor dampness or in behavior related to non- intervened life-style factors.
Conclusions: The dietary intervention seemed to be successful. The observed reduced smoking behavior could
not be attributed to the intervention program, and the latter had no effect on indoor dampness

Early eczema and the risk of childhood asthma: a prospective, population-based study
<p>Abstract</p> <p>Background</p> <p>Severe eczema in young children is associated with an increased risk of developing asthma and rhino-conjunctivitis. In the general population, however, most cases of eczema are mild to moderate. In an unselected cohort, we studied the risk of current asthma and the co-existence of allergy-related diseases at 6 years of age among children with and without eczema at 2 years of age.</p> <p>Methods</p> <p>Questionnaires assessing various environmental exposures and health variables were administered at 2 years of age. An identical health questionnaire was completed at 6 years of age. The clinical investigation of a random subsample ascertained eczema diagnoses, and missing data were handled by multiple imputation analyses.</p> <p>Results</p> <p>The estimate for the association between eczema at 2 years and current asthma at 6 years was OR=1.80 (95% CI 1.10-2.96). Four of ten children with eczema at 6 years had the onset of eczema after the age of 2 years, but the co-existence of different allergy-related diseases at 6 years was higher among those with the onset of eczema before 2 years of age.</p> <p>Conclusions</p> <p>Although most cases of eczema in the general population were mild to moderate, early eczema was associated with an increased risk of developing childhood asthma. These findings support the hypothesis of an atopic march in the general population.</p> <p>Trial registration</p> <p>The Prevention of Allergy among Children in Trondheim study has been identified as ISRCTN28090297 in the international Current Controlled Trials database</p
