  1. Notes: Results from 3 regression models of each outcome on full set of explanatory variables. Separate categories for “Refused to answer” and “Don’t know/Missing” were included in the model (see Table 6 in Appendix for these results). Models adjusted for blocking variables (category of school and presence of home economics class). Ref reference category, IRR incidence rate ratios, obtained from a Poisson regression, OR Odds ratios, obtained from logistic regression, msgs messages, CI confidence interval, SD standard deviation, IQR Interquartile range
