Background. The effectiveness of lifestyle behavior interventions with
children to reduce chronic disease risks in adulthood assumes stabili
ty in the lifestyle behaviors across time. The transition out of high
school is a time when many changes occur in social roles, e.g., changi
ng schools, leaving the parents' home, changing peers, finding employm
ent, getting married, and becoming a parent. Cancer risk behaviors may
increase as a result of some of these social role changes. Methods. C
oncepts relevant to the stability or change in lifestyle behaviors thr
ough the transition out of high school are presented, Literature conce
rning diet, smoking, smokeless tobacco, alcohol, physical activity, se
xual practices, and sun exposure behaviors through the transition is r
eviewed. Results. Most lifestyle behaviors display increasing cancer r
isk around the transition out of high school. Different levels of chan
ge were associated with different pathways through the transition. Inc
onsistent findings were obtained in the pattern of co-occurrence of th
ese behaviors. Conclusion. Priority research includes establishing the
pattern of co-occurrence of lifestyle behaviors through the transitio
n, identifying the pattern of tracking of each behavior through the tr
ansition, and identifying the primary influences on the group values a
nd tracking of the behaviors. Longitudinal research is needed to contr
ol for preexisting differences between pathways through the transition
