Guys, it's to help kids actually access health care:
Concerns about privacy can prevent adolescents from seeking care.4 In two large nationally representative surveys, approximately a quarter of middle and high school students reported having forgone health care they needed.5 In one of these, a third of students who did not seek care reported that one of their reasons was "not wanting to tell their parents."6 The impact of privacy concerns when adolescents require specific services to address sensitive health issues is likely much higher. For example, half of single, sexually active females younger than 18 years surveyed in family planning clinics in Wisconsin reported that they would stop using the clinics if parental notification for prescription contraceptives were mandatory; another one in 10 reported that they would delay or discontinue use of specific services, such as services for STDs.7 Furthermore, only 1% of adolescent girls who indicated they would stop using family planning services reported that they would also stop having intercourse; the vast majority reported that they would continue to have sex, but use less effective contraceptive methods or none at a11.8
