The relationships among body size, biological sex, ethnicity, and healthy lifestyles in adolescents

Abstract

Purpose. The purposes of this study were to (a) determine whether actual weight, biological sex, and race/ethnicity were related to differences of weight perception, nutrition and activity knowledge, perceived difficulty, attitudes, and choices about living a healthy lifestyle in adolescents; and (b) describe the relationships among these variables. Design and Methods. This was a cross-sectional descriptive, correlational design with 404 adolescents. Results. Perception of weight was more accurate in overweight adolescents. Teens who reported difficulty in leading a healthy lifestyle reported less healthy choices, attitudes, and knowledge. Practice Implications. Findings suggest tailored interventions should consider biological sex and race/ethnicity. © 2011, Wiley Periodicals, Inc.
