Oregon 2016-2020 Pregnancy Risk Assessment Monitoring System (PRAMS) Survey Analysis: Association between Postpartum Cannabis Use and Breastfeeding Duration Among Washington County Mothers. Público

Abstract

Background: Conflicting study results and limitations of prior study designs have made it difficult to determine the impact of postpartum marijuana use on breastfeeding duration.

 

Research Aims: (1) Report demographics of Washington County, Oregon mothers who used marijuana 0 – 6 months postpartum; (2) to examine the association between postpartum marijuana use and breastfeeding duration.

Methods: Secondary cross-sectional survey data collected between 2016 and 2020 by the Organ Health Authority were analyzed using R studio. Analytic sample consisted of 25,059 (weighted) mothers who participated in the 2016 – 2020 Oregon Pregnancy Risk Assessment Monitoring System (PRAMS) survey. Chi-square analyses were conducted to understand the differences in breastfeeding duration based on select demographic criteria. The association of postpartum marijuana use on breastfeeding duration (defined as breastfeeding or providing expressed milk to an infant for at least 3 months) was evaluated using logistic regression modeling and adjusted odds ratios (aOR).

 

 Results: The total number of participants on the analytic sample for this study was n=25059. Among women in our study sample n = 20596 (82.2%) breastfed for ≥3 months. Among mothers who breastfed for ≥3months, 2.7% (n=547) self-reported postpartum marijuana use.  After controlling for postpartum depression, mother’s race/ethnicity, mothers age, and postpartum cigarette use, no association between postpartum marijuana use and breastfeeding duration was found. Women who experienced postpartum depression breastfed less when compared to women who did not experience postpartum depression (aOR= 0.4493, CI [0.24, 0.85]).

Conclusion: There was no association between postpartum marijuana use and breastfeeding duration among women in our sample; however postpartum depression was associated with breastfeeding duration ≤3months. Further programmatic interventions should focus on increasing rates of breastfeeding among women who experience postpartum depression. Future surveillance planning should make significant efforts towards developing methods for collecting data from non-respondents.
