Introduction and Objectives: Both asthma prevalence and the percentage of cesarean sections have increased in parallel in recent years. Research studies suggest an increased risk of developing atopic diseases and asthma after cesarean section birth compared to vaginal delivery. The main objective of this study is to analyze the risk of asthma admission after cesarean section birth compared to vaginal delivery in the pediatric population.
Population and Methods: Retrospective observational analytical case-control study from 1993 to 2020. The cases include all admitted patients to our health area hospital, for patients aged 7 to 16 diagnosed with asthma. For each case, a control without a diagnosis of asthma is selected with the same age, and that has also caused an episode of admission.
Results: A total of 290 admission episodes with a diagnosis of asthma were obtained, caused by 155 patients. Out of these, 145 cases with documented delivery types were selected. For cases, 155 controls were selected. The historical proportion of cesarean sections in the asthmatic group is 18.6%, compared to 14.2% in the non-asthmatic group. There is a statistically non-significant difference of 4.4% more cesarean sections in the asthmatic group compared to the control group.
Discussion: We have not demonstrated a statistically significant association between being born by cesarean section and an increased risk of asthma admission. Based on this finding, we cannot conclude that there is an association between being born by cesarean section and a higher risk of suffering from asthma, unlike what has been postulated in other research studies.
