    • Results from the ACHA-NCHA IIc, Fall 2015 to Spring 2019

      Changes were made to the ACHA-NCHA IIb survey instrument beginning Fall 2015. The ACHA-NCHA IIc now includes E-cigarettes in items #8A and #9A. Items #20 (sexual partners) , #47 (sex and gender identity), and #48 (sexual orientation) have been revisited. A new variable has been computed based on sex at birth and gender identity. The new variable is used to sort cases into groups-female, male, non-binary, and missing for reporting purposes.
