This journal article describes a study looking at associations between severe pregnancy complications in New Jersey and municipal spending on services for residents.
Primary Takeaways
The authors found that levels of severe pregnancy complications varied considerably by city. They also found that in cities that spent more on services such as transportation, health, housing, libraries, and welfare, women were less likely to have severe pregnancy complications, compared to women in cities that spent less on those same resident services. Conversely, in cities that spent more on police, women were more likely to have severe pregnancy complications.
Overview and Objectives
The United States has a high rate of death related to pregnancy, which is often linked to complications of pregnancy, and New Jersey is one of the states with the highest rates of severe pregnancy complications. The authors wanted to know whether severe pregnancy complication rates vary by city in New Jersey. They also wanted to see whether city spending that is directly or indirectly related to health (including during pregnancy) contributes to rates of pregnancy complications.
Hypothesis or Approach
The authors analyzed over one million New Jersey birth files, covering a ten-year period (2008–2018). They matched the birth records to maternal hospital discharge records and data on city spending. They used hospital discharge codes and Centers for Disease Control and Prevention criteria to identify women with severe pregnancy complications.
How This Influences Change
“The findings from this study indicate that place matters for Severe Maternal Morbidity (SMM) and that interventions at the municipal level that go beyond reproductive healthcare may be an effective approach for reducing SMM,” the authors write.

Importance: Severe maternal morbidity (SMM) is a major cause of maternal mortality, yet little is known about geographic variation in SMM or factors associated with geographical variation at the local level. Municipal governments incur substantial expenditures providing services that are an essential part of residents’ lives, but associations between municipal expenditures and SMM have not been previously examined.
Objective: To investigate variation in rates of SMM across municipalities in New Jersey (NJ), the contributions of individual-level characteristics and municipal expenditures to that variation, and associations between municipal expenditures that are directly or indirectly related to health and SMM.
Design: This cross-sectional study analyzed 2008-2018 NJ birth files linked to maternal hospital discharge records and U.S. Census municipal expenditures data.
Setting: The birth files contain all birth records for NJ and hospital discharge records contain information from all in-patient hospitalizations in NJ over the study period.
Participants: 1,005,240 birth records were matched to maternal discharge records and expenditures data.
Exposures: Individual-level characteristics and municipality per capita expenditures on education; public health; fire and ambulance; parks, recreation, and natural resources; housing and community development; public welfare; police; transportation; and libraries.
Main Outcome and Measure: Women with SMM were identified using diagnosis and procedure codes for indicators of SMM based on criteria developed by the Centers for Disease Control and Prevention.
Results: Of 1,005,240 women (45% white, 15% Black, 11% Asian, 28% Hispanic), 20,071 (2%) had SMM. There was substantial municipality-level variation in SMM that was not fully explained by demographic characteristics. Municipal expenditures on fire/ambulance, transportation, health, housing, libraries, and welfare were negatively associated with SMM; $1,000 higher annual expenditure per capita in these categories was associated with 27-60% (odds ratios: 0.40 [95% CI, 0.19–0.82] to 0.73 [95% CI, 0.56–0.94]) lower odds of SMM. Expenditures on police were positively associated with SMM (odds ratio, 1.14; 95% CI, 1.04– 1.25).
Conclusions and Relevance: The findings that various types of municipal expenditures were strongly associated with SMM suggest that interventions at the municipal level that go beyond reproductive health care may be an effective approach for reducing SMM and potentially maternal mortality.
