support children with disabilities and their families and to extend the services of rehabilitation treatment of disabled children and the financial support to cover the services. 2. Health Service (Article 24 of CRC) Basic Health of the Child (CRC/C/KOR/3-4, para. 324 and 331-339) 67. According to the 2009 Comprehensive Study on the Status of Children and Youth by the Ministry of Health and Welfare, the average frequency of medical checkup in a year among the children aged 19 or below recorded 0.6. The ratio of essential and optional vaccinations among the children aged 2 or below varied depending upon the family income level: 52% in the families below the poverty line; 64.3% in those immediately above the poverty line; and 78.4% in the other families. At present, the government subsidies are only applied to essential vaccinations, and the cost of vaccinations for the children in their early childhood varies widely, depending upon the presence or absence of the local government subsidy (by a margin of up to 420,000 won), the hospitals and the distribution channels of vaccinations. 68. According to the Youth Health data released by the Statistics Korea in 2010, the obesity ratio of the elementary and secondary school students was rated at 13.2%. The Comprehensive Study on the Status of Children and Youth reveals that 45.1% of the children aged 12~18 did little exercise all through the week while the largest percentage of the children aged 3~11 did some exercise for 1~3 hours a week. By age group and income level, the incidence of child obesity was the highest in the poor class among the children aged 11 or below, and in the class immediately above the poverty line among the children aged 12~18. The Government started the health management service for obese and weak children, as part of its investment in the local community services (voucher projects), in 2011 but the service is not available to all the children in need. The service is provided for a limited time of one year only to the children who have succeeded in making a timely application for the service. 69. The Government needs to increase the financial support for vaccinations to narrow the gap in vaccination ratios among the families of different income levels, with a view to promoting the basic health of children. Furthermore, the Government needs to resolve the difference in the vaccination cost caused by the local community subsidies, hospitals or distribution channels, by promoting equitability among different local communities and supervising and controlling the hospitals and distribution channels. In an effort to prevent child obesity, the Government needs to ensure that the child health management service is available in a universal and consistent way, not to a selected group or for a limited period of time.
