Malnutrition in infants under six months old is a pressing global health issue, with over 10 million infants currently estimated to be underweight. A recent study published in BMJ Global Health analyzed data from 56 low- and middle-income countries to assess the prevalence of malnutrition among infants.
The study, led by researchers at the London School of Hygiene & Tropical Medicine (LSHTM) and the Emergency Nutrition Network (ENN), utilized data from nationally-representative household surveys to determine the weight, height, and age of over 50,000 infants under six months old. The findings revealed alarming rates of underweight, wasting, stunting, and low birth weight among these infants.
According to the study, approximately 17.4% of infants were underweight, 15.5% showed signs of wasting, 19.9% were stunted, and 15% were born with a low birth weight. When extrapolated to all low- and middle-income countries globally, these numbers suggest that millions of infants are affected by malnutrition.
Marko Kerac, Clinical Associate Professor at LSHTM and lead author of the study, emphasized the devastating impact of malnutrition on child mortality rates. He highlighted the importance of national datasets like the Demographic and Health Surveys (DHS) in tracking and addressing this hidden problem. Without access to reliable data, progress in combating infant malnutrition could be hindered.
Marie McGrath, Technical Director at ENN and co-author of the study, emphasized the need for targeted interventions within national health services to identify and manage cases of malnutrition in infants. Growth monitoring and early vaccination play a crucial role in detecting and addressing malnutrition in this vulnerable population.
The study also raised concerns about the lack of data on other indicators of malnutrition and the outdated nature of some survey data. The researchers suggested that underweight scores may be a better indicator of malnutrition in infants under six months and supported the updated WHO malnutrition guidelines that include underweight as a criteria for intervention.
Overall, the study underscores the urgent need for global health organizations, governments, and communities to prioritize the well-being of infants under six months old. Addressing malnutrition in this vulnerable population is essential for reducing child mortality rates and ensuring healthy development for future generations.
