Greater numbers of children are on the move than ever before. In 2015, the number of forcibly displaced people across the globe reached 65.3 million. Of the more than 1 million migrants, asylum seekers, and refugees who arrived in Europe in 2015, nearly one third were children, and 90,000 of these children were unaccompanied.Child migrants are among the most vulnerable, even after arriving at their destination. The health of migrant children is related to their health status before their journey, the conditions during their journey and at their destination, and the physical and mental health of their caregivers. These children may have experienced numerous forms of trauma including war, violence, separation from family, and exploitation. They may suffer from malnutrition and communicable diseases including vaccine-preventable diseases. Pregnant women, newborns, and unaccompanied minors are particularly vulnerable groups. Social isolation is a major risk factor for all migrant children that compound other health risks even after settlement in their new home. Lack of health information, language, and cultural differences serve as major barriers to adequate, timely, and appropriate healthcare. In spite the challenges they face, migrant children demonstrate remarkable resilience that can be nurtured to promote good mental and physical health.Migrant children, irrespective of their legal status, are entitled to healthcare of the same standard provided to children in the resident population, as stated in the UN Convention on the Rights of the Child. It is imperative that the health sector includes informed health workers who are able to identify the health risks and needs of these children and provide culturally competent care. In order to achieve this and promote the rights of migrant children to optimal health and well-being, ISSOP recommends that⢠Programmes and activities designed to promote and protect migrant child health and well-being must be designed in collaboration with all sectors involved, including the education and social sectors, and should always include the voices of migrant children and their families.⢠Health services should be readily available and easily accessible for preventive, maintenance, and curative care regardless of the child's legal status. Care should be of the same standard as care provided to the local population.⢠Health information should be provided that is culturally sensitive and readily available in a language that migrant children and families can understand.⢠Medical interpreters and cultural mediators should be available during healthcare encounters, and personnel working with migrants should receive training in cultural competence.⢠Health professionals should not participate in age determination until methods with acceptable scientific and ethical standards have been developed.⢠Professionals working with migrant children and families should have access to emotional support services.⢠Evidence-based best practices in the care of migrant children should be identifie...
