Abstract
Background: The impact of the burgeoning policies and programmes aimed at optimising the population’s preconception health requires evaluation through national surveillance. As initial steps towards a national surveillance infrastructure, we present the first national-level report card on the state of preconception health of women in England based on indicators routinely recorded through maternity services and identify 10 initial priority indicators for ongoing surveillance.
Methods: This cross-sectional population-based study used data from 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). Data on 32 indicators were routinely collected at booking appointments. We analysed the prevalence of each indicator across the overall population and sociodemographic subgroups. Ten of these indicators were prioritised for ongoing surveillance based on modifiability, prevalence, data quality and ranking by multidisciplinary UK experts.
Findings: The three most prevalent indicators were: proportion of smokers who did not quit smoking during the year before pregnancy (85.0%), 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, most strongly and consistently for smoking around the time of conception and pre-existing mental health conditions. The 10 indicators prioritised were: not taking folic acid supplementation before pregnancy, obesity, complex social factors, living in a most deprived area, smoking around the time of conception, overweight, pre-existing mental health condition, pre-existing physical health condition, previous pregnancy loss and previous obstetric complication.
Interpretation: Our findings suggest important opportunities to improve the state of preconception health and reduce sociodemographic 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.
