A similar highly significant trend was found for the prevalence of sex in students who drank more frequently (Pearsons χ 2 = 69.48, df3, p < 0.001; Linear-by-Linear Association χ 2 = 63.68, df1, p < 0.001).

Among drinkers, there was a significant trend for increased frequency of drinking by age (Pearsons χ 2 = 11.711, df3, p = 0.008; Linear by linear association χ 2 = 6.411, df1, p = 0.011).
The odds of having sex was higher among children responding negatively to school and general wellbeing indicators, however, these did not reach statistical significance.
