Objectives Abortion incidence is correlated with seasonal trends in conceptions and births. This retrospective review looks at monthly abortion incidence to detect a seasonal trend. Study design Data on abortion incidence in 2012 were obtained from the Kentucky Department of Vital Statistics. A regression analysis was performed to detect differences in abortion annualized rates by month. Results A total of 3810 abortions analyzed showed a trend in abortion incidence peaking in February and March with 444 and 378 abortions per month, respectively, compared to a mean of 299 in other months (p<.001). This trend persisted for second-trimester abortions with 64 and 56 abortions per month in February and March, respectively, compared to a mean of 30 in other months (p<.001). Conclusion The peak in first-trimester abortions correlate with the expected peaks of December conceptions. However, the same trend in second-trimester abortions suggests that women are delaying care.
