Mind the Gap: Unraveling Mental Health Disparities in America's Diverse Landscape

Background: Mental health disparities persist as a significant public health concern in the United States, with certain populations experiencing disproportionate burdens of mental illness and barriers to care. This systematic review aims to synthesize current evidence on mental health disparities across various demographic groups and identify key factors contributing to these inequities. Methods: We conducted a comprehensive search of peer-reviewed literature published between 2010 and 2024 using PubMed, PsycINFO, and Scopus databases. Studies examining mental health outcomes, access to care, and treatment efficacy across racial/ethnic, socioeconomic, gender, sexual orientation, and geographic groups in the US were included. Two independent reviewers screened articles, extracted data, and assessed study quality. Results: Of 2,345 initially identified studies, 127 met inclusion criteria. Consistent disparities were observed across multiple domains, with racial/ethnic minorities, low-income individuals, LGBTQ+ populations, and rural residents experiencing higher rates of mental health disorders, lower access to quality care, and poorer treatment outcomes. Key contributing factors included systemic racism, socioeconomic barriers, stigma, lack of culturally competent care, and inadequate insurance coverage. Conclusion: This review highlights persistent and multifaceted mental health disparities in the US. Addressing these inequities requires comprehensive policy interventions, increased funding for community-based mental health services, improved cultural competence in healthcare delivery, and targeted research to develop effective, culturally-tailored interventions for underserved populations.
