Teenagers with more siblings have worse mental health: studyBy Ian Sample / The GuardianFrom Cain and Abel and the Brothers Karamazov to Cinderella, the warmth and support provided by siblings has hardly been taken for granted. In China, the teenagers with no siblings fared best for mental health. In the US, children who had no siblings or only one were found to have similar mental health. Overall, mental health was worse the more siblings the teenagers had, with greater impacts seen for teenagers with older siblings, and when brothers and sisters were closely spaced in age.
