| Abstract: | The objective of this study was to assess the relationship between mode of delivery at birth and asthma by following all children born in Rochester, Minn, between 1976 and 1982. From the birth certificate, the authors determined mode of delivery (cesarean section vs vaginal delivery). Asthma status during the first 7 years of life was ascertained from comprehensive medical record reviews. The association between mode of delivery and asthma status was evaluated in a proportional hazards model adjusted for sex, birth weight, maternal education, and maternal age. The cumulative incidence rates of asthma among children who were born by cesarean section and vaginal delivery were 3.2% versus 2.6%, 4.6% versus 4.6%, 4.6% versus 5.8%, and 5.7% versus 6.7% at the 1st, 3rd, 5th, and 7th years of life, respectively. The adjusted hazard ratios for cesarean section in predicting asthma and wheezing episode were 0.93 (95% CI, 0.6-1.4; P=.71) and 0.93 (95% CI, 0.7-1.3; P=.67), respectively. |

| Discussion: | Unfortunately the authors could not contrast 'in labor cesareans' and 'non-labor cesareans'. We can assume that in this population born between 1976 and 1982 most c-sections occurred during labor. |
