(Umea University) The coexistence of both undernutrition and overweight/obesity, a phenomenon called double burden of malnutrition, is a global public health challenge existing at all levels from the individual to the population, especially in low-to middle-income countries. Research on malnutrition in Indonesia found that about 20 percent of households exhibit double burden of malnutrition. Umeå University researcher Masoud Vaezghasemi emphasizes the importance of social and contextual determinants in fighting against both forms of malnutrition.
