CRC/C/DZA/CO/3-4 (b) Limited post-natal care which only one third of women benefit from; (c) The problem of availability of medicines in the State party; (d) The nutritional status of young children which has not improved since 2002; one child in ten being underweight and one in five being stunted; and (e) The poor conditions of work of health-care professionals. 58. The Committee reiterates its recommendation (CRC/C/15/Add.269, para. 57, 2005) that the State party ensure that appropriate resources be allocated for the health sector, and develop and implement comprehensive policies and programmes for improving the health situation of children and to facilitate greater and equal access to quality primary-health services by mothers and children in all areas of the country in order to end the disparities in health-care provision between the different areas. The Committee also urges the State party to take more effective measures to address the nutritional status of young children. The Committee draw the attention of the State party to the fact that ensuring decent conditions of work for professionals in the health sector is essential to the provision of quality services for children. Adolescent health 59. The Committee is concerned that sexual and reproductive health services for adolescents are scarce and that sexual and reproductive health education remains underdeveloped. The Committee is also concerned that knowledge of HIV transmission and prevention is low among adolescents. 60. Taking into account the Committee’s general comment No. 4 (2003) on adolescent health, the Committee urges the State party to design and implement an inter-sectoral public policy for health, sexual and reproductive rights aimed at adolescents within and outside the educational system and taking into account sexual and reproductive rights, healthy sexuality, prevention of unplanned pregnancies, sexually transmitted diseases, HIV/AIDS, and the accessibility and use of condoms and other contraceptives. Standard of living 61. The Committee notes as positive the significant progress made by the State party to eradicate poverty and in particular the increase in social investment and social transfer programmes. The Committee is however concerned that structural and long-term investment measures to maintain families out of poverty have been insufficient to maintain families out of poverty and to reduce the high level of disparities in the quality and level of access to social services, with rural regions and city suburbs being in the most disadvantaged situation. The Committee is also concerned that: (a) Over a million of families live in slums and millions in precarious housing conditions due to the housing crisis. The Committee is also concerned that families displaced during the “black decade” have not benefited from any programme to facilitate their safe return to their place of origin or to meet their specific housing needs in localities where they currently live; (b) Social programmes targeting families in the most vulnerable situations such as the free education and health services and social housing programmes hardly reach the poorest children; (c) Families and children of disappeared persons are requested to obtain a court declaration stating that the disappeared relative has died to obtain social security benefits including child education benefits; and 14
