Summary of results

Around one in four pregnancies end in a miscarriage. Despite how common they are, there is a lack of research on the topic. We studied if miscarriage risk is different depending on level of education, income, or occupational status in the UK. We used survey data collected from individuals born in 1970, who have been interviewed several times over the years (British Cohort Study 1970). We did not find differences in miscarriage risk by education, income, or occupation status among those, who experienced pregnancies beteween ages 16 and 42. Understanding which characteristics are (not) associated with miscarriage risk can help improve miscarriage healthcare.

Surveys are an interesting source to study miscarriage, but respondents may not report all their miscarriage experiences, for example, because of recall issues, the sensitivity of the topic, or discomfort in disclosing a pregnancy loss. In this study, we estimated that almost all miscarriages (92%) were reported in the FECOND survey, conducted in France in 2010-11. We also found that around 14% of the pregnancies reported in the survey resulted in a miscarriage. While thise share did not vary bu education, older age at the start of the pregnancy was associated with an increasing miscarriage risk.
