A Cross-sectional study on the relationship between birth order and asthma among 1st and 2nd year students of the College of Medicine of De La Salle-Health Sciences Campus, Academic Year 2006-2007. Objective: To determine if there is an association between birth order and asthma among 1st and 2nd year medical students of DLS-HSC 2006-2007. Design: The research design was cross sectional since birth order, and the presence and absence of asthma, is at one point in time. Setting: College of Medicine of De La Salle-Health Sciences Campus Dasmariñas, Cavite. Subjects: The study included 1st and 2nd year medical students of DLS-HSC. The sample size was 152; simple random sampling was used for data collection. Each student was given questionnaires and was compiled into a database using the Epi Info Software 2000. Baseline characteristics of subjects were analyzed using descriptive statistics. Chi square test was done to determine statistical significance of presence of asthma on first born and later born. Prevalence ratio was computed to determine the association between asthma and birth order. Results: Among the 152 medical students, the mean age was 21.5 and the mode was 21. Majority of the study population based on sex was female and based on civil status majority were single. The proportion of 1st and 2nd year medical students having the presence of asthma was 23%. The proportion of first born who has presence of asthma was 30.4% and who has absence of asthma was 69.6%. The proportion of later born who has presence of asthma was 15.1% and who has absence of asthma was 84.9%. The Chi square showed that the p value was 0.041. The prevalence ratio was 2.01. Conclusion: First born were 2.01x more likely to have asthma than later born. Birth order has an effect on the presence and absence of asthma. Recommendations: It is recommended to use laboratory test to test for any atopic diseases to know there was really any history of asthma.
