The location of this research is PKU Muhammadiyah Gamping Yogyakarta with a sample of 30 respondents and the sampling technique is Simple Random Sampling. The data analysis technique used in this research is chi square. Research Results: Factors related to the incidence of blighted ovum pregnancy are parity factors as indicated by a p-value of 0.004 where the p-value is smaller than the significance value with an error rate of 5% (0.05). This shows that there is a relationship between the parity variable and the incidence of blighted ovum pregnancy. For the nutrition variable, the p-value is 0.151 where the p-value is greater than the significance value with an error rate of 5% (0.05).
