title: Clustering of (Un)Healthy Behaviors in Adolescents from Dunedin, New Zealand.
abstract: OBJECTIVE
  Healthy lifestyle habits set the stage for healthy behaviors in adulthood. We examined clustering of health behaviors (physical activity [PA], screen time, fruit and vegetable [F&V] intake) and weight status in New Zealand adolescents.
  
  
  METHODS
  Adolescents from Dunedin, New Zealand (N = 1300; 49.0% male; 15.3±1.4 years) completed a questionnaire about PA, screen time (TV/computer/video games), and F&V intake. Height and weight were measured. A 2-step cluster analysis was completed.
  
  
  RESULTS
  Few adolescents met individual guidelines (17.9% PA, 14.2% screen time, 29.8% F&V intake) and only 2.5% met all 3 guidelines. Weight status was 3.2%/69.6%/20.5%/6.8% for underweight/healthy weight/overweight/obese. Six clusters were identified: (1) non-adherent (not meeting any guideline) adolescents with healthy weight (38.8%); (2) non-adherent with unhealthy weight (15.4%); (3) semi-adherent (meeting some guidelines) with unhealthy weight (11.8%); (4) physically active with healthy weight (13.4%); (5) low screen time with healthy weight (7.1%); and (6) healthy F&V intake with healthy weight (13.5%).
  
  
  CONCLUSIONS
  Few adolescents met recommended health behavior guidelines; yet, two-thirds had a healthy weight. The identified clusters had distinct sociodemographic and lifestyle characteristics. Future interventions should be comprehensive and consider socioeconomic structural factors.
