title: All in the family: correlations between parents' and adolescent siblings' weight and weight-related behaviors.
abstract: OBJECTIVE
  To examine whether and how parents' and adolescent siblings' weight and weight-related behaviors are correlated. Results will inform which family members may be important to include in adolescent obesity prevention interventions.
  
  
  METHODS
  Data from two linked population-based studies, EAT 2010 and F-EAT, were used for cross-sectional analyses. Parents (n = 58; 91% females; mean age = 41.7 years) and adolescent siblings (sibling #1 n = 58, 50% girls, mean age = 14.3 years; sibling #2 n = 58, 64% girls, mean age = 14.8 years) were socioeconomically and racially/ethnically diverse.
  
  
  RESULTS
  Some weight-related behaviors between adolescent siblings were significantly positively correlated (i.e., fast food consumption, breakfast frequency, sedentary patterns, p < 0.05). There were no significant correlations between parents' weight and weight-related behaviors and adolescent siblings' same behaviors. Some of the significant correlations found between adolescent siblings' weight-related behaviors were statistically different from correlations between parents' and adolescent siblings' weight-related behaviors.
  
  
  CONCLUSIONS
  Although not consistently, adolescent siblings' weight-related behaviors were significantly correlated as compared with parents' and adolescent siblings' weight-related behaviors. It may be important to consider including siblings in adolescent obesity prevention interventions or in recommendations healthcare providers give to adolescents regarding their weight and weight-related behaviors.
