Objective: This study aims to identify Nutrition Transition (NT) profiles in Argentina (2005?2013), and to assess their association with obesity in the adult population.Design: A large cross sectional study was performed considering datasets of nationally representative surveys. A Multiple Correspondence Analysis coupled with a Hierarchical Clustering was conducted to detect geographical clusters of association among sociodemographic and NT indicators. Multilevel logistic regression models were used to assess the effect of NT profile (proxy variable of contextual order) on obesity occurrence. Setting: Firstly, we used geographically aggregated data about the adult and child populations in Argentina. Secondly, we defined the population of adults who participated in the National Survey of Chronic Disease Risk Factors (2013) as the study population.Subjects: 24 geographical units that make up the territory of Argentina and 32,365 individuals over 18 living in towns of at least 5,000 people.Results: Three NT profiles were identified and called: 1) ?Socionutritional lag? (characterised by undernutrition and socioeconomically disadvantaged conditions), 2) ?Double burden of malnutrition? (undernutrition and overweight in highly urbanized scenarios), and 3) ?Incipient socionutritional improvement? (low prevalence of malnutrition and more favourable poverty indicator values). Profiles 1) and 2) were significantly associated with a higher risk of obesity occurrence in adults (OR=1.16, 95%CI 1.02, 1.32 and 1.44, 95%CI 1.26, 1.64, respectively), compared with profile 3. Conclusion: Argentina is facing different NT processes, where sociodemographic factors play a major role in shaping diverse NT profiles. Most of the identified profiles were linked to obesity burden in adults.
