To establish mediation, four equations were tested: 1) parent encouragement for PA predicting
adolescent body satisfaction; 2) parent encouragement for PA predicting the mediator (adolescent PA); 3) adolescent PA predicting body satisfaction; and 4) adolescent PA and parent encouragement of PA predicting
adolescent body satisfaction.
Examining the moderating effect of adolescent sex on this association revealed that adolescent PA no longer mediated the association between perceived encouragement for PA from fathers and
adolescent body satisfaction, and sex moderated this association.
Step 3: Predicting Age 16
Adolescent Body Satisfaction with Adolescent Leisure - time Exercise Behavior Measured at Age 15
Moderated mediation model for the associations between fathers» encouragement for PA at age 15 and
adolescent body satisfaction at age 16 as mediated by adolescent PA at age 15 and moderated by adolescent sex.
While previous research has found that PA and body satisfaction are positively associated [6, 40] and that parental encouragement for PA is associated with child PA [21 — 23], this is the first study to longitudinally examine the mediating influence of adolescent PA behavior on the association between parental encouragement for PA and
adolescent body satisfaction one year later.
Therefore, the purposes of this study were to: (1) longitudinally assess whether adolescent PA at age 15 mediates the effect of parental encouragement for PA at age 15 for predicting
adolescent body satisfaction at age 16, while controlling for body mass index (BMI), and (2) examine the extent that adolescent sex moderated the mediation of adolescent PA on the association between parental encouragement for PA and body satisfaction.
Step 4: Predicting Age 16
Adolescent Body Satisfaction with Fathers» Encouragement for Physical Activity and Adolescent Leisure - time Exercise Behavior Measured at Age 15
We hypothesized that perceived fathers» and mothers» encouragement for PA would positively predict adolescent PA and body satisfaction, and that greater adolescent PA would explain this relationship between parental encouragement for PA at age 15 and
adolescent body satisfaction at age 16 [6, 8, 21].

RESULTS: Experiencing parent encouragement to diet as an
adolescent was significantly associated with a higher risk of overweight or obesity, dieting, binge eating, engaging in unhealthy weight control behaviors, and lower
body satisfaction 15 years later as a parent, after adjusting for sociodemographics and baseline measures of the outcomes (P <.05).
Step 1: Predicting Age 16
Adolescents»
Body Satisfaction with Fathers» Encouragement for Physical Activity Measured at Age 15
Perceived encouragement for PA from fathers, but not mothers, at age 15, was significantly associated with
adolescent PA at age 15 and
body satisfaction scores at age 16.
Moreover, strength of the present study is that mothers» and fathers» encouragement for PA on
adolescent PA and subsequent
body satisfaction were examined separately.
Collectively, our findings suggest that additional longitudinal research among
adolescent boys and girls is needed examining different types of parental encouragement to better understand the influence of parental encouragement on
adolescent PA, as well as the link with
body satisfaction.
Importantly, findings from the present study also suggest that parental influence on
adolescent PA may vary by sex, such that perceived encouragement for PA from fathers, but not mothers, predicted
body satisfaction among their sons, but not daughters.
Adolescents reporting higher PA behavior and perceived encouragement for PA from fathers at age 15 had higher
body satisfaction scores at age 16.
Lastly, findings from the present study indicate
adolescent sex may moderate associations among parental encouragement for PA,
adolescent PA, and
body satisfaction; thus, future work should also consider examining the moderating effects of sex between same sex and opposite sex parents.
To confirm mediation, Models 1 - 3 need to be significant, but when
adolescent PA is added to model 4, encouragement for PA is no longer a significant predictor of
body satisfaction.
Specifically, fathers play an important role in promoting
body satisfaction by encouraging
adolescents to be physically active.
Two independent regression analyses were conducted to examine separately the contribution of perceived mother's and father's encouragement for PA at age 15 for predicting
adolescent body image
satisfaction at age 16.
In other words, fathers may play an instrumental role in
adolescents»
body image
satisfaction by positively influencing PA behavior.
Moreover, our small study sample size may explain the lack of support for our second hypothesis that
adolescent sex would moderate the association between
adolescent PA and
body satisfaction.
