of the 1,475 participating in the survey) answered all five questions. It is not known if
the young people who failed to answer one or more of these questions are different in
any way to the young people who answered all five questions whose information is
presented below. If the young people who failed to answer all the questions are
different with respect to their risk factor prevalence then this would introduce a bias into
the survey results. Young people were told that their information was strictly confidential
and that it would not be possible to identify their answers or attribute specific answers to
individuals. They were also asked to complete all questions even those questions that
they felt were not relevant to them. Nevertheless, it is possible that young people may
have not answered the question as they did not want to admit that they has smoked,
drank alcohol, tried drugs, etc. Furthermore, it is possible that young people did not
answer the question as they felt it was irrelevant to them. It is also possible (particularly
for the youngest age groups) that young people ran out of time and that the questions at
the end of the questionnaire were incomplete (questionnaire order: exercise; 5-A-DAY;
alcohol; smoking; and drug use).
Table 162 gives the prevalence of multiple risk factors for boys by school year (Year 7
aged 11-12 years to Year 11 aged 15-16 years) as well as the total estimated number of
boys in Hull with this combination of risk factors. These figures should be interpreted
cautiously. For many combinations of risk factors, there are only one or two boys who
stated that they undertook that particular combination (out of the approximate 200 who
answered all five questions 51 ) and therefore when extrapolating to the total estimated
number of boys in Hull with this combination of risk factors the estimates could be quite
different (as the totals are based on percentages which potentially are subject to
considerable random variation).
