Background: Diabetes and mental health conditions frequently co-occur, with depression and anxiety affecting up to 20-30% of people with diabetes. These comorbidities worsen glycemic control, adherence, and quality of life, yet mental health is often neglected in diabetes care. Integrating mental health services into diabetes management is recommended by international organizations to improve patient outcomes. Objectives: To systematically review the evidence on integrated mental health interventions in diabetes care, compared to usual diabetes care, in improving patient outcomes (glycemic control, mental health, adherence, quality of life). Methods: We searched PubMed/MEDLINE, Embase, PsycINFO, and Scopus (2000 through July 2024) for studies of diabetes care integrating mental health support (e.g., collaborative care, co-location, stepped care, or digital interventions). Inclusion criteria were controlled trials or cohort studies involving individuals with type 1 or type 2 diabetes receiving an integrated mental health intervention, with outcomes on glycemic control and/or mental health. Two reviewers independently screened titles/abstracts and full texts, with disagreements resolved by consensus. Data on study design, population, intervention components, and outcomes were extracted. Risk of bias was assessed using Cochrane or appropriate tools. Results: Out of records identified, 64 studies met inclusion criteria (primarily randomized controlled trials). Integrated care models consistently improved depression and anxiety outcomes and diabetes-specific distress, and yielded modest but significant reductions in glycated hemoglobin (HbA1c) compared to usual care. Many interventions also enhanced treatment adherence and self-management behaviors. For example, collaborative care trials showed greater depression remission rates and small HbA1c improvements (~0.3-0.5% absolute reduction) relative to standard care. Co-located care in diabetes clinics was associated with reduced diabetes distress, depression scores, and HbA1c over 12 months. Digital health integrations (telepsychiatry, online cognitive-behavioral therapy) improved psychological outcomes and adherence, with some reporting slight improvements in glycemic control. Integrated approaches often increased uptake of mental health services (e.g., higher referral completion rates) and showed high patient satisfaction. A subset of studies reported fewer emergency visits and hospitalizations with integrated care, and one economic analysis found collaborative care cost-effective in primary care settings. Conclusions: Integrating mental health into diabetes care leads to better mental health outcomes and modest improvements in glycemic control, without adverse effects. Heterogeneity across studies is noted, but the overall evidence supports multidisciplinary, patient-centered care models to address the psychosocial needs of people with diabetes. Healthcare systems should prioritize implementing and scaling integrated care, accompanied by provider training and policy support, to improve outcomes and bridge the persistent treatment gap. Future research should focus on long-term effectiveness, cost-effectiveness, and strategies to reach diverse populations.

OBJECTIVE: Perinatal anxiety is one of the most common yet least systematically addressed complications of preg- nancy and childbirth. Despite abundant evidence that collaborative and integrated care models improve maternal outcomes, obstetric practice still lacks a defined operational standard for addressing anxiety alongside routine obstetric care. Fragmented screening, insufficient referral systems, and financing barriers continue to delay intervention, widening inequities across populations and settings. METHODS: This opinion article synthesizes recent evidence (2010-2025) from PubMed, Google Scholar, and professional guidelines to propose a practical framework for embedding mental health care within obstetric workflows. Drawing upon studies from high- and low-resource contexts, we outline a ten-point minimum standard for perinatal-anxiety management and a three-tier maturity model that describes the progressive integration of collaborative care-from basic screening to digitally supported, team-based systems. The model identifies measurable implementation metrics and policy levers that enable sustainability and equity. RESULTS: Rather than advocating new research, this article translates two decades of findings into a clinically actionable standard. It emphasizes the central role of ob- stetric teams in early detection, stepped care, and follow-up through coordination with mental-health professionals. CONCLUSIONS: Integrating mental health into obstetric practice is both a moral and operational imperative. By adopting the proposed minimum standard and maturity model, health systems can transform perinatal anxiety care from discre- tionary innovation to routine expectation-achieving faster response, broader access, and better maternal-infant out- comes worldwide.
