Editorial: Equity/inequality, diversity and inclusion in child and adolescent mental health - a perspective from the South Asian region.

Over 1.8 billion people, about a quarter of the world's population live in the seven countries of South Asia: Afghanistan, Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. The population is characterized by a significant demographic youth bulge, with over 40% under the age of 18. This young population poses challenges related to ensuring their well-being and development. Issues such as poverty, undernutrition, lack of early stimulation, limited access to quality education and health care, and gender disparities persist in large parts of South Asia, affecting the lives of many children and adolescents. The promotion of child and adolescent mental health remains a challenge. Accumulating evidence suggests that early interventions can provide long-term health and socioeconomic benefits by prevention of the onset of mental health problems and their development into chronic disorders. This needs to be coupled with specialist services that can cater to the needs of children with greater needs, and support the community and schools-based non-specialist led services. Addressing child and adolescent mental health in South Asia presents a window of opportunity, because this regional youth bulge can contribute significantly to the global economy of the future.
