Hansen, Tonje Elisabeth; Evjenth, Bjørg; Holt, jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)<p><i>Aim - </i>The aim of this study was to identify possible risk factors for current asthma revealed by two studies in Northern Norway in 1985 and 2008 and to evaluate these factors contributing to the increased prevalence of asthma over these 23 years. <p><i>Methods - </i>As part of the ‘Asthma and allergy study among schoolchildren in Nordland county’ we performed a case–control study (70.0% ... -
The prevalence and possible risk factors of asthma in a subarctic child population. A study of asthma and allergy among schoolchildren i Nordland county
Hansen, Tonje Elisabeth (Doctoral thesis; Doktorgradsavhandling, 2019-05-07)Astmaepidemien de siste årtiene, har ført til at astma er blitt den vanligste kroniske sykdommen blant barn i den vestlige verden. Selv om studier fra ulike steder viser stor variasjon i forekomsten av astma, allergisk øye- og nesekatarr (rhinokonjunktivitt) og eksem, har man på tross av utstrakt forskning ikke funnet årsaken til sykdommene eller entydige forebyggende tiltak. Denne avhandlingen ... -
