Facing co-occurrence of underweight and overweight populations worldwide

Purpose - The purpose of this paper is to investigate the situation and trends regarding prevalence of underweight, overweight, and undernourished populations worldwide. Thus, we defend that the conditions of hunger, underweight, overweight, and obesity are seen as anomalies resulting from nutritional and dietary food insecurity related to the concept of malnutrition. Design/methodology/approach - This investigation was conducted through an ecological study, using indicators related to undernourishment, underweight, and overweight. Data, obtained through the WHO and United Nations, were analyzed through scatter plots and angular coefficient from linear regression. Findings - Evidence suggests that some nations have high levels of undernourished and overweight populations at the same time. Results showed a significant reduction in the prevalence of underweight children and a significant increase in the prevalence of overweight children worldwide. Western Pacific has shown declining trends in both overweight and underweight children. Southern Africa has shown a strong increase in its child overweight population and no downward trend in its underweight child population. Practical implications - The authors defend that programs and actions better aligned to diagnoses of some countries that face problems related to both underweight and overweight/obesity conditions are needed. This investigation can help public and private efforts to combat underweight and overweight diagnoses worldwide. Originality/value - The authors present evidence of the co-occurrence of underweight and overweight in child populations worldwide. Thus, the authors show alarming trends regarding to these diagnoses.
