Objective: Verifying the ability of reproducibility of a scale that assesses the attitude to obesity and develops percentile standard for university students from the region of Maule (Chile). Material and Methods: A survey was conducted on 918 university students (535 men and 383 women) from the region of Maule (Chile). Weight and height were evaluated. Body mass index (BMI) was calculated and attitude scale was applied to obesity. The LMS method was used to develop percentile curves. Results: The scale of attitude to obesity (EAO) showed acceptable values of Cronbach's alpha (0.70 men) and women 0.73). The percentile references were dealers in P15, P50 and P85 by allowing value indicator (Preference/Rejection, Concern/Selflessness and Will/Apathy), age range and gender. Conclusions: The EAO is a reliable reference percentile and proposals are an alternative to diagnose, control and monitor obesity attitude of university students.
