The effects on children of participating in studies of minors' access to tobacco.

BACKGROUND

Ethical concerns about the effect on children of participating in studies of minors' access to tobacco are frequently raised by human subjects' committees but have not been assessed empirically. Data on the effects of such participation on the smoking-related behavior of minors are needed.

METHOD

Forty-eight children were screened and selected in 1993 to participate in a study of minors' access to tobacco. All 48 attended tobacco-education workshops, none were smokers, and all denied an intention to smoke in the future. Thirty-six of them were (randomly) assigned to the experimental group who made 2,567 purchase attempts (PAs) between 1993 and 1994, and 11 were assigned to a control group who made no PAs. Two years after screening (1 year after completion of the study) all were sent a follow-up questionnaire assessing current intentions to smoke and other smoking-related behaviors.

RESULTS

Minors who made PAs were significantly less likely than those who did not to indicate an intention to smoke in the future; only 12.5% of experimental vs 71.4% of control group minors intended to (or might) smoke in the future. Minors who made PAs also were significantly more likely than those who had not to discuss smoking with peers and to encourage peers and family to quit smoking or to avoid initiating smoking. In 2,567 PAs, minors were never physically threatened, touched, or harmed, and they were treated with verbal hostility in only 73 (2.8%) of their PAs.

CONCLUSIONS

These findings suggest that participating in a study of minors' access to tobacco does not increase smoking or intentions to smoke among the minors. Rather, such participation may be associated with low intentions to smoke and with increased tobacco-control efforts on the part of the minors. The effects of participating in such studies may be positive for the minors, their families, and their peers. Participating in such studies does not place minors at risk for physical harm, and their risk for verbal abuse is low.
