According to a survey by the C.S. Mott Children's Hospital, obesity, bullying and drug abuse were the top three childhood health concerns in 2015, as cited by nearly 2,000 adults aged 18 and older. Internet safety and sexting came in at fourth and sixth place, respectively; notably, sexting moved dramatically from 13th place in 2014. Researchers pointed out that many problems highlighted in the poll are health issues without clear cures, including internet safety concerns and cyberbullying, which adds to adults’ uncertainty about the best prevention and coping options.
