a
Due to colinearity between percent condom use in the last week and the number of times used condoms in the last week, it was excluded from the multivariate model
b
Condom use in the last week was calculated by a percent of the number of vaginal sex acts reported in question 2 divided by the number of condoms reported in the past week. If participants reported more condoms than sex acts, the percent could be more than 100 %
