Prepregnancy Diabetes and Perinatal Mental Illness: A Population-Based Latent Class Analysis

Area of Science:

• Reproductive Health
• Endocrinology
• Psychiatry

Background:

• Prepregnancy diabetes is a significant health concern for women of reproductive age.
• Perinatal mental illness poses risks to both mother and child.
• Understanding the specific risks associated with diabetes in pregnancy is crucial for effective intervention.

Purpose of the Study:

• To investigate the association between prepregnancy diabetes and the risk of perinatal mental illness.
• To explore how diabetes duration, complexity, and intensity of care influence this risk.
• To identify specific subgroups of women with diabetes who may benefit from enhanced mental health support.

Main Methods:

• Population-based cohort study in Ontario, Canada (2005-2015).
• Inclusion of women aged 15-49 with singleton livebirths and no recent mental illness.
• Latent class analysis to categorize women with diabetes based on duration, complexity, and care intensity; modified Poisson regression to estimate risks.

Main Results:

• Women with prepregnancy diabetes had a higher likelihood of developing perinatal mental illness (18.1% vs. 16.0%).
• Three distinct latent classes of diabetes were identified, with varying risk profiles.
• Elevated perinatal mental illness risk was observed across all diabetes classes compared to women without diabetes, though not significant for one class after adjustment.

Conclusions:

• Prepregnancy diabetes is linked to an increased risk of perinatal mental illness.
• Diabetes management strategies and preconception care should incorporate mental health screening and support.
• Further research into tailored interventions for different diabetes profiles is warranted.
