Declarations
:
: This study was based on a secondary analysis of an existing dataset which were conducted by the former National Health and Family Planning Commission (NHFPC) of China in 2017. We used only tabulated data from the survey without any individual information, and human subject protection is not an issue here. All methods of the survey were carried out in accordance with relevant guidelines and were approved by the IRB of the former NHFPC of China, a state organization. Informed consent was obtained from all participants (or their parent or legal guardian in the case of all minor participants) before the questionnaire was administered.
