What is normal body weight? Perceptions around "average" and "healthy" body weight among adolescents in Indiana.

Abstract

Biological normalcy is a framework that investigates relationship(s) between statistical norms and normative views/beliefs around particular traits. This study assessed the relationships between perceptions of average body weight, healthy body weight, and weight status among adolescents. Adolescents recruited in southcentral Indiana, United States (n=123) completed online questionnaires for demographics and body weight perceptions. Silhouettes from the Stunkard Figure Rating Scale measured perceived weight status, perceived average body weight, and perceived healthy body weight. Height and weight were measured to calculate body mass index-for-age percentiles. A subsample (n=11) provided descriptions of "average," "healthy," and "normal" bodies during semi-structured interviews. As perceived average body weight increased, selections of "healthy" silhouettes shifted downward, with smaller female silhouettes being marked healthy more often and larger male silhouettes being marked healthy less often. Additionally, perceived weight status was positively associated with perceptions around average body weight and lowest body weight perceived to be healthy for female and male silhouettes. Qualitative data demonstrated significant overlap in adolescents' descriptions of "average," "healthy," and "normal" bodies as well as dual meanings for the term "normal" in adolescents' views of body weight. Perceived weight status appears to play a role in adolescents' conceptualizations of average and healthy body weight. Additionally, Qualitative and quantitative data indicated that perceived body weight norms were associated with normative perceptions around what healthy bodies look like. This study demonstrates relationships between statistical norms and normative views around body weight, underscoring the duality in how body weight is understood to be "normal" among adolescents.
