Women's preconception health in England: a report card based on cross‐sectional analysis of national maternity services data from 2018/2019.

Objective: To present the first national‐level report card on the state of women's preconception health in England. Design: Cross‐sectional population‐based study. Setting: Maternity services, England. Population: All pregnant women in England with a first antenatal (booking) appointment recorded in the national Maternity Services Dataset (MSDS) from April 2018 to March 2019 (n = 652 880). Methods: We analysed the prevalence of 32 preconception indicator measures in the overall population and across socio‐demographic subgroups. Ten of these indicators were prioritised for ongoing surveillance based on modifiability, prevalence, data quality and ranking by multidisciplinary UK experts. Results: The three most prevalent indicators were the proportion of the 22.9% of women who smoked 1 year before pregnancy who did not quit smoking before pregnancy (85.0%), those who had not taken folic acid supplementation before pregnancy (72.7%) and previous pregnancy loss (38.9%). Inequalities were observed by age, ethnicity and area‐based deprivation level. The ten indicators prioritised were not taking folic acid supplementation before pregnancy, obesity, complex social factors, living in the most deprived areas, smoking around the time of conception, overweight, pre‐existing mental health condition, pre‐existing physical health condition, previous pregnancy loss and previous obstetric complication. Conclusions: Our findings suggest important opportunities to improve the state of preconception health and reduce socio‐demographic inequalities for women in England. In addition to MSDS data, other national data sources that record further and possibly better quality indicators could be explored and linked to build a comprehensive surveillance infrastructure.
