Objective To test a predictive model of the associations among prepregnancy body mass index (BMI), third-trimester biological and behavioral variables, and symptoms of depression at 4 weeks postpartum. Design Secondary data analysis from a longitudinal, biobehavioral repeated measures study of women during the third trimester of pregnancy through 6 months postpartum. Setting Communities surrounding a midwestern and a western U.S. city. Participants Participants were 111 women enrolled in their third trimesters of pregnancy who were studied through 4 weeks postpartum. Methods Whole blood and saliva were used for biological measures, and validated questionnaires were used for behavioral measures. Principal component analysis and path analysis with principal component variables were used to iteratively test the model. Results There were three statistically significant direct effects in the model: the path from prepregnancy BMI to inflammation, the path from prepregnancy BMI to stress, and the path from stress to symptoms of depression at 4 weeks postpartum. Indirect effects of prepregnancy BMI on postpartum depression through intervening variables were not statistically significant, nor was the model-based total effect of prepregnancy BMI on postpartum depression. Conclusion Stress was significantly linked to prepregnancy BMI and postpartum depression. This finding highlights continuing possibilities for improving outcomes for mothers, infants, and families through stress-mitigating preventative strategies.

The United States has greater prevalence of mental illness and substance use disorders than other developed countries, and pregnant women are disproportionately affected. The current global COVID-19 pandemic, through the exacerbation of psychological distress, unevenly affects the vulnerable population of pregnant women. Social distancing measures and widespread closures of businesses secondary to COVID-19 are likely to continue for the foreseeable future and to further magnify psychosocial risk factors. We propose the use of a social determinants of health framework to integrate behavioral health considerations into prenatal care and to guide the implementation of universal and comprehensive psychosocial assessment in pregnancy. As the most numerous and well-trusted health care professionals, nurses are ideally positioned to influence program and policy decisions at the community and regional levels and to advocate for the full integration of psychosocial screening and behavioral health into prenatal and postpartum care as core components.

Nurse-midwives provide significant health care to underserved and vulnerable women, yet there is limited information about the nature of nurse-midwifery practices and compensation for services. This study reports the results of a Colorado statewide survey of nurse-midwives (N = 217). Electronic survey was utilized to detail practice in seven areas: demographics, type of practice, compensation, leadership, legislative priorities,teaching involvement, and practice satisfaction. Responses (N = 114) were analyzed using SPSS 13.0. Results found wide variation in compensation and practice types. Respondents largely worked in urban settings, cared for low to moderate risk patients, and were generally older and White. Restriction from medical staff membership, prescriptive authority constraints, and liability issues were practice limitations. While teaching a wide variety of learners, nurse-midwives do limited mentoring of nurse-midwifery students, a finding which is concerning given the decreasing numbers of nurse-midwives. Findings are compared to known national data, with implications for the provision of health care services detailed.
