BACKGROUND Body image perception (BIP) is a multidimensional construction focused on physical appearance and functioning of the body (Sabiston et al., 2019). BIP determine behaviors related to body weight, physical activity and eating, and are influenced by several psychological and social factors. PURPOSE: To describe and identify relationships between BIP, physical activity and eating habits in a Latin American adult sample. METHODS: A descriptive cross-sectional study, in which participate 131 adults (71 females and 60 males) from Argentina (65.6%), Colombia (32.8%), Mexico (0.8%) and Uruguay (0.8%), who voluntarily answered a pro forma online survey (age: 36.78 ± 10.73 years; weight: 71.22 ± 14.61 Kg.; height: 168 ± 10 cm.). Self-reported variables were weight, height, BIP, active or inactive physical participation, according to World Health Organization exercise recommendations (WHO Ex. Rec.) and eating habits. RESULTS: 50.4% of the sample reported not ideal BIP (60.6% females); and 60.3% (both males and females) reported being active according to WHO Ex. Rec. The Body Mass Index (BMI), determined by self-reported weight and height, was normal for 58.8% (females 70.4%), 29% overweight, 11.5% obese, and 0.8% underweight. Moderate correlation coefficient (r) was found between BIP and BMI (r = 0.58; p < 0.05), greater in females (r = 0.73; p < 0.05). Pearson's Chi-square test is not significant (ns) between BIP and physical activity (3.367; p = 0.186). Spearman test is ns between BIP and eating habits (r = -0.10; p = 0.257). In addition, 40% of population chooses health as high priority option, when considering their daily food intake, and 67.9% showed unhealthy eating habits. CONCLUSION: Based on the results, we conclude that BIP has a moderate r with BMI, mainly for females, who reported BIP profile which is more real and representative to the diagnosis of body weight. Also, in this sample, physical activity habits were adequate, but eating habits were predominantly unhealthy.
