The New York City health department has launched the Healthy Teens Initiative, which aims to make sexual and reproductive health care more accessible. Service centers will receive a new tool kit aimed at making the facilities teen-friendly. Caregivers also are being offered training sessions to help implement tool kit recommendations. The program kicked off in the Bronx and will expand citywide. Officials say the initiative is necessary because about half of the city's teens are sexually active and are at risk of contracting HIV and other STDs.
