Maladaptive eating styles are patterns of eating-related behavior that are detrimental to overall health. Risky eating behaviors are specific components of eating styles. The objective, to analyze maladaptive eating styles and risky eating behaviors associated with sociodemographic characteristics in adults living in northern Chile. A total of 802 women (60.1%) and men (38.9%) from northern Chile participated. The Dutch eating behavior questionnaire and the E-TONA structured interview were used. Mean difference, Pearson’s chi-square and odds ratios tests were performed. Women presented higher levels in all the maladaptive eating styles evaluated, although significant differences were only evidenced in emotional eating. Additionally, with respect to risky eating behaviors, there is parity in the presence between men and women, although the behaviors performed by men are linked to overeating while in women to the management of negative emotions. The influence of sociodemographic characteristics and the eating environment needs to be further explored.
