CRC/GC/2003/4 page 7 private institutions for adolescents (schools, institutions for disabled adolescents, juvenile reformatories, etc.), and training and monitoring of personnel in charge of institutionalized children or who otherwise have contact with children through their work, including the police; and (b) interpersonal violence among adolescents, including by supporting adequate parenting and opportunities for social and educational development in early childhood, fostering non-violent cultural norms and values (as foreseen in article 29 of the Convention), strictly controlling firearms and restricting access to alcohol and drugs. 24. In light of articles 3, 6, 12, 19 and 24 (3) of the Convention, States parties should take all effective measures to eliminate all acts and activities which threaten the right to life of adolescents, including honour killings. The Committee strongly urges States parties to develop and implement awareness-raising campaigns, education programmes and legislation aimed at changing prevailing attitudes, and address gender roles and stereotypes that contribute to harmful traditional practices. Further, States parties should facilitate the establishment of multidisciplinary information and advice centres regarding the harmful aspects of some traditional practices, including early marriage and female genital mutilation. 25. The Committee is concerned about the influence exerted on adolescent health behaviours by the marketing of unhealthy products and lifestyles. In line with article 17 of the Convention, States parties are urged to protect adolescents from information that is harmful to their health and development, while underscoring their right to information and material from diverse national and international sources. States parties are therefore urged to regulate or prohibit information on and marketing of substances such as alcohol and tobacco, particularly when it targets children and adolescents4. III. INFORMATION, SKILLS DEVELOPMENT, COUNSELLING, AND HEALTH SERVICES 26. Adolescents have the right to access adequate information essential for their health and development and for their ability to participate meaningfully in society. It is the obligation of States parties to ensure that all adolescent girls and boys, both in and out of school, are provided with, and not denied, accurate and appropriate information on how to protect their health and development and practise healthy behaviours. This should include information on the use and abuse, of tobacco, alcohol and other substances, safe and respectful social and sexual behaviours, diet and physical activity. 27. In order to act adequately on the information, adolescents need to develop the skills necessary, including self-care skills, such as how to plan and prepare nutritionally balanced meals and proper personal hygiene habits, and skills for dealing with particular social situations such as interpersonal communication, decision-making, and coping with stress and conflict. States parties should stimulate and support opportunities to build such skills through, inter alia, formal and informal education and training programmes, youth organizations and the media. 28. In light of articles 3, 17 and 24 of the Convention, States parties should provide adolescents with access to sexual and reproductive information, including on family planning and contraceptives, the dangers of early pregnancy, the prevention of HIV/AIDS and the prevention and treatment of sexually transmitted diseases (STDs). In addition, States parties should ensure that they have access to appropriate information, regardless of their marital status
