Background. Weight-loss behaviours are highly prevalent among adolescents, and body weight perception motivates weight control
practices. However, little is known about the association of body weight perception, and weight control practices among teenagers
in Mauritius. The aim of this study is to investigate the relationships between actual body weight, body weight perception, and
weight control practices among teenagers. Methods. A questionnaire-based survey was used to collect data on anthropometric
measurements, weight perception and weight control practices from a sample of 180 male and female students (90 boys and 90
girls) aged between 13 and 18 years old. Results. Based on BMI, 11.7% of students were overweight. Overall, 43.3% of respondents
reported trying to lose weight (61.1% girls and 25.6% boys). Weight-loss behaviours were more prevalent among girls. Among the
weight-loss teens, 88.5% students perceived themselves as overweight even though only 19.2% were overweight. Reducing fat intake
(84.6%), exercising (80.8%), and increasing intake of fruits and vegetables (73.1%) and decreasing intake of sugar (66.7%) were the
most commonly reported methods to lose weight. Conclusion. Body weight perception was poorly associated with actual weight
status. Gender difference was observed in body weight perception
