particularly to meeting the educational and service needs of adolescents to enable them to deal in a positive and responsible way with their sexuality", taking into account the rights of the child to access to information, privacy, confidentiality, respect and informed consent, as well as the responsibilities, rights and duties of parents and legal guardians to provide, in a manner consistent with the evolving capacities of the child, appropriate direction and guidance in the exercise by the child of the rights recognized in the Convention on the Rights of the Child, and in conformity with the Convention on the Elimination of All Forms of Discrimination against Women. In all actions concerning children, the best interests of the child shall be a primary consideration. Support should be given to integral sexual education for young people with parental support and guidance that stresses the responsibility of males for their own sexuality and fertility and that help them exercise their responsibilities. 268. More than 15 million girls aged 15 to 19 give birth each year. Motherhood at a very young age entails complications during pregnancy and delivery and a risk of maternal death that is much greater than average. The children of young mothers have higher levels of morbidity and mortality. Early child-bearing continues to be an impediment to improvements in the educational, economic and social status of women in all parts of the world. Overall, early marriage and early motherhood can severely curtail educational and employment opportunities and are likely to have a long-term adverse impact on their and their children’s quality of life. 269. Sexual violence and sexually transmitted diseases, including HIV/AIDS, have a devastating effect on children’s health, and girls are more vulnerable than boys to the consequences of unprotected and premature sexual relations. Girls often face pressures to engage in sexual activity. Due to such factors as their youth, social pressures, lack of protective laws, or failure to enforce laws, girls are more vulnerable to all kinds of violence, particularly sexual violence, including rape, sexual abuse, sexual exploitation, trafficking, possibly the sale of their organs and tissues, and forced labour. 270. The girl child with disabilities faces additional barriers and needs to be ensured non-discrimination and equal enjoyment of all human rights and fundamental freedoms in accordance with the Standard Rules on the Equalization of Opportunities for Persons with Disabilities. 30/ 271. Some children are particularly vulnerable, especially the abandoned, homeless and displaced, street children, children in areas in conflict, and children who are discriminated against because they belong to an ethnic or racial minority group. 272. All barriers must therefore be eliminated to enable girls without exception to develop their full potential and skills through equal access to education and training, nutrition, physical and mental health care and related information. 273. In addressing issues concerning children and youth, Governments should promote an active and visible policy of mainstreaming a gender perspective into all policies and programmes so that before decisions are taken, an analysis is made of the effects on girls and boys, respectively. -111-
