Maternal characteristics have significantly changed over two decades, with trends varying by socioeconomic status. These shifts provide context for obstetric outcomes and inform health planning.
Area of Science:
- Reproductive Health
- Public Health
- Sociology
Background:
- Understanding evolving maternal demographics is crucial for public health.
- Socioeconomic disparities can influence maternal health and obstetric care.
Purpose of the Study:
- To analyze changes in maternal characteristics stratified by socioeconomic status.
- To provide context for recent trends in obstetric procedures and outcomes.
- To inform health planning initiatives.
Main Methods:
- Study included all Nova Scotia residents who delivered between 1988 and 2007.
- Maternal data sourced from the Nova Scotia Atlee Perinatal Database.
- Socioeconomic status linked via federal income tax files (1988-2003).
Main Results:
- Births to women under 20 increased in lower income groups, while decreasing in higher income groups.
- Births to women aged 35+ increased by 136%; births to women weighing over 90 kg also rose.
- Smoking rates decreased across all socioeconomic groups; births following a perinatal death declined by 52%.
Conclusions:
- Significant secular changes in maternal characteristics have occurred over two decades.
- The impact of these changes on maternal and infant health varies by socioeconomic status.
- These findings are vital for targeted public health interventions and resource allocation.
