Object The study aimed to evaluate the prevalence and associated factors of under‐reporter (UR) and over‐reporter (OR) of energy intake (EI) in Latin American (LA) adolescents and adults participating in the ELANS study. Methods Multicenter cross‐sectional study including a representative sample of urban population from eight LA countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Venezuela). Two 24‐h dietary recalls and physical activity data using IPAQ‐long version questionnaire were collected from 9218 participants (15–65 years old). Misreporting was identified using ±1.5SD cut‐off points to statistically compare reported EI with predicted total energy expenditure. Associations between misreporting of EI and covariates were examined by Chi‐square test (p<0.05). Results In average, 13% were UR and 14% were OR. Chile had the highest percentage of UR (22%), the lowest percentage of OR (7%) and showed the highest obesity prevalence. Peru showed the lowest percentage of UR (5%) and Ecuador the highest percentage of OR (20%). We found no differences between the prevalence of misreporting and sex. Individuals with lower educations showed the highest percentage of misreporting (UR=14%, OR=15%). We observed more UR and fewer OR among overweight and obese subjects. UR was associated with higher weight, waist and neck circumference and body mass index (p<0.05). Also, UR was significantly associated with lower intake of energy, fats and carbohydrates, and higher protein intake. In relation to plausible respondents, EI on average was 32% lower in UR and 43% higher in OR. Proportion of UR was higher in older group (15%), widowers (19%), high socioeconomic level (15%), undefined race (18%), physically active (14%) and obese (21%). The proportion of OR was higher in adolescents (21%), single (16%), low socioeconomic level (15%), non‐Caucasian (16%), physically active (15%) and underweight (37%). Conclusion Our study supports other findings that it is important not only to identify individuals that do not accurately report food intake, but also the factors that determine this misreporting, improving the interpretation of diet‐related diseases.
