NOTE: All percentages are weighted to the Connecticut population and adjusted for differential selection probabilities, rates of nonresponse, and poststratification. Adjusted percentages control for respondent age and race/ethnicity and for other respondent and relative characteristics that were significantly associated with unknown cancer history in final logistic regression models. Cells for variables that were not applicable to a particular model are labeled NA; cells for variables that were eliminated through backward stepwise regression are blank.

  • *Same or younger generation as the respondent includes siblings, children, and/or nieces and nephews; older includes parents, aunts, and uncles; oldest includes grandparents.
