Changes in Body Weight Perception Could Undermine Public Health Interventions to Tackle Obesity<\/p>

A study involving more than 745,000 adolescents from 41 countries across Europe and North America identified an increase in the amount of teenagers who underestimate their body weight.<\/p>

Tracking data from 2002 to 2018, the peer-reviewed findings, published in Child and Adolescent Obesity<\/a>, demonstrate a noticeable decrease in those who overestimate their weight too.<\/p>

The team of international experts, who carried out the research, warn these shifting trends in body weight perception could reduce the effectiveness of public health interventions aimed at weight reduction in young people.<\/p>

\u201cDuring this impressionable age, body weight perception may influence a young person\u2019s lifestyle choices, such as the amount and types of food they eat and their exercise habits,<\/i>\u201d says lead author Doctor Anouk Geraets<\/a>, from the Department of Social Sciences, at the University of Luxembourg.<\/p>

\u201cSo it\u2019s concerning that we\u2019re seeing a trend where fewer adolescents perceive themselves as being overweight \u2013 as this could undermine ongoing efforts to tackle increasing levels of obesity in this age group. Young people who underestimate their weight and therefore do not consider themselves to be overweight may not feel they need to lose excess weight and, as a result, they may make unhealthy lifestyle choices.<\/i>\u201d<\/p>

A person\u2019s perception of their body weight may not accurately reflect their actual weight. A discrepancy in body weight perception (BWP) may either be an underestimation (where actual weight is higher than perceived weight) or an overestimation (where actual weight is lower than perceived weight).<\/p>

In the present study, the researchers examined survey data from 746,121 11-, 13- and 15-year-olds from 41 countries collected at four-yearly intervals between 2002 and 2018 in the International Health Behaviour in School-Aged Children (HBSC), a WHO collaborative study.<\/p>

The team modeled trends in BWP among adolescents across different countries over time, making adjustments for age, gender, and family socioeconomic status. They found:<\/p>
