Typologies of common maternal mental disorders and associated factors: a quantitative life course study applied to...

We aim to identify trajectories of probable maternal common mental disorders (CMD), as well as risk and protective factors associated with maternal mental health among postpartum women during the pandemic using life course theory approach.

Prospective individual level cohort study from the Iracema-COVID Study.

Mothers (n=335) at postpartum period who delivered during the COVID-19 pandemic in the fourth largest city in Brazil.

Probable CMDs were accessed using validated instruments in five cohort waves at postpartum period. Sequence analyses (SA) were employed to extract CMD trajectories, and a set of generalised binomial logistic and log-Poisson multivariable regression models with robust variance were employed to assess risk and protective factors for probable CMDs diagnosis.

Trajectories patterns of probable maternal common mental disorders.

Fit indices demonstrated a two-cluster-SA solution of probable CMD. The patterns of probable CMDs indicated that 335 mothers were clustered into occasional/transitory (n=240, 71.64%) and mostly/persistent (n=95, 28.36%) CMD trajectories. We found that mothers with low education (OR: 2.44; 95% CI 1.13 to 5.23), single (OR: 1.97; 95% CI 1.03 to 3.75) or in a stable union (OR: 2.00; 95% CI 1.02 to 3.90) and travel time spent to access the nearest primary healthcare unit (OR: 1.02; 95% CI 1.006 to 1.04) were associated with increased OR of belonging to the mostly/persistent CMD trajectory. Deprived green areas acted as a risk factor to maternal CMDs prevalence (OR: 1.37; 95% CI 1.002 to 1.87).

This study provides evidence that individual vulnerabilities and neighbourhood deprivation play an important role in understanding maternal mental health, beyond the patterns and trajectories of probable maternal CMD due to issues confronted during the COVID-19 outbreak in the northeastern region of Brazil. Policies to prevent and treat maternal mental health issues and improvement in neighbourhood deprivation need to be developed and addressed to avoid exacerbation of probable maternal CMDs.
