The study included 14,800 participants, and it found that the odds of adverse health outcomes in adulthood were 13% – 52% higher among those who reported having unmet health care needs during adolescence.
The reasons adolescents may not be obtaining proper care vary. 37.2% said proper care was perceived as having low importance in their life, 22.7% said they were worried about the negative consequences of health care, and 32% said they had issues with access to care. Other studies have shown that teenagers may forgo health care due to concerns about cost, confidentiality, staff unfriendliness, poor communications, and being treated with a lack of respect. 
The authors of this study found that unmet health care need was common in all insurance categories and sociodemographic groups. They concluded that reducing unmet health care needs among adolescents may be a highly effective investment to improve health outcomes.
