AB  - Introduction:The prevalence of Asthma and Allergic rhinitis has been shown to be increasing over the last few decades both in developed and developing countries.This study evaluated the changing trends in the prevalence of Asthma and Allergic rhinitis among children in Mysore,South India.Methodology:The trends were evaluated among children aged 6-14 years via the ISAAC core questionnaire which was self administered by the parents in 1998,2003,2008,2013. Univariate and multivariate analysis was conducted to evaluate independent association of early life factors and asthma and allergic rhinitis.Results:In 2013, a total of 1800 questionnaire were distributed and 1307 questionnaire were returned,response rate: 72.6%.The prevalence of asthma was estimated to be 17.14% and allergic rhinitis was 21.29%.The corresponding prevalence in 1998,2003,2008 for asthma was 4.%,6% and 9% and allergic rhinitis was 6.%,9% and 13% respectively.Twin children were found to have higher risk of asthma [2.95%{1.43-6.06}]on multivariate analysis and attending child care facility was found to be protective[o.68%{0.49-0.94}].Presence of elder siblings were found to have a higher risk for allergic rhinitis on multivariate analysis and younger siblings,term delivery and normal birth weight were protective.Conclusion:The increasing trend observed over 1998 to 2008 showed a steeper increase over the last five years,which needs further evaluation.
