CRC/C/BTN/CO/2 page 12 (b) Undertake a comprehensive and multidisciplinary study to assess the scope of adolescent health problems including mental health issues; (c) Take into account the Committee’s general comment No. 4 (2003) on adolescent health and development in the context of the Convention on the Rights of the Child.. Standard of living 56. The Committee welcomes the improved access to safe drinking water and basic sanitation and notes that the objective of the Ninth Five Year National Development Plan was to improve the poor living conditions of large segments of the population, in particular in rural areas and to provide the entire population with access to safe drinking water, sanitation and health services. The Committee however is concerned about the lack of data on the percentage of the population which has access to these basic provisions. 57. The Committee recommends that, in accordance with articles 4 and 27 of the Convention, the State party improve its coordination and reinforce its efforts to allocate adequate human and financial resources to provide support and material assistance, with a particular focus on the most marginalized and disadvantaged families, and to guarantee the right of children to an adequate standard of living. In this regard, the State party is furthermore encouraged to seek international cooperation and assistance. HIV/AIDS 58. The Committee welcomes the State party’s policy on providing free antiretroviral therapy. Furthermore, it notes the relatively low HIV/AIDS prevalence rate and that State party is formulating a comprehensive prevention policy. However, the Committee is concerned that the reported cases of HIV are increasing; including through mother-to-child transmission and that infected children may face stigmatization. The Committee is also concerned over the low use of condoms. 59. The Committee recommends that the State party, while taking into account the Committee’s general comment No. 3 (2003) on HIV/AIDS and the rights of the child and the international guidelines on HIV/AIDS and human rights by OHCHR and the Joint United Nations Programme on HIV/AIDS (2006): (a) Strengthen its preventive efforts by conducting campaigns and programmes in order to raise awareness on HIV/AIDS including on prevention methods and the use of contraceptives; (b) Strengthen measures to prevent mother to child transmission; (c) Provide psycho-social support to HIV/AIDS infected and affected children and their families as well as advocacy on early interventions;
