Risk factors for symptoms of childhood asthma, allergic rhinoconjunctivitis and eczema in the Pacific: an ISAAC Phase III study.
METHODS
Phase III of the International Study of Asthma and Allergies in Childhood (ISAAC) was conducted in eight Pacific countries, five of which (Samoa, Fiji, Tokelau, French Polynesia and New Caledonia) collected environmental questionnaire (EQ) data. We report the findings of the EQ analyses below.


RESULTS
The major factors associated with current wheeze were regular margarine consumption (prevalence odds ratio [POR] 1.19, 95%CI 1.01-1.40), paracetamol use (POR 1.35, 95%CI 1.11-1.64), electric cooking (POR 1.42, 95%CI 1.11-1.80), regular exercise (POR 1.44, 95%CI 1.18-1.75) and maternal smoking (POR 1.16, 95%CI 1.01-1.33). Protective factors included having older siblings (two or more POR 0.69, 95%CI 0.58-0.82; one POR 0.86, 95%CI 0.71-1.05), and being born in the country of the survey (POR 0.74, 95%CI 0.63-0.87). Risk factors for rhinoconjunctivitis included regular consumption of meat, butter, margarine and nuts, regular exercise, regular television viewing, paracetamol use and passive smoking. Eczema was associated with regular meat, pasta and butter consumption, regular television viewing, paracetamol use and passive smoking.


CONCLUSIONS
Regular meat and margarine consumption, paracetamol use, electric cooking and passive smoking are risk factors for symptoms of asthma, rhinoconjunctivitis and eczema in the Pacific. However, most of these associations were weak, and account for only a small proportion of cases.
