The relationship between wasting and stunting in young children: A systematic review

In 2014, the Emergency Nutrition Network published a report on the relationship between wasting and stunting. We aim to review evidence generated since that review to better understand the implications for improving child nutrition, health and survival. We conducted a systematic review following PRISMA guidelines, registered with PROSPERO. We identified search terms that describe wasting and stunting and the relationship between the two. We included studies related to children under five from low- and middle-income countries that assessed both ponderal growth/wasting and linear growth/stunting and the association between the two. We included 45 studies. The review found the peak incidence of both wasting and stunting is between birth and 3 months. There is a strong association between the two conditions whereby episodes of wasting contribute to stunting and, to a lesser extent, stunting leads to wasting. Children with multiple anthropometric deficits, including concurrent stunting and wasting, have the highest risk of near-term mortality when compared with children with any one deficit alone. Furthermore, evidence suggests that the use of mid-upper-arm circumference combined with weight-for-age Z score might effectively identify children at most risk of near-term mortality. Wasting and stunting, driven by common factors, frequently occur in the same child, either simultaneously or at different moments through their life course. Evidence of a process of accumulation of nutritional deficits and increased risk of mortality over a child's life demonstrates the pressing need for integrated policy, financing and programmatic approaches to the prevention and treatment of child malnutrition.     

More than just a seat at the table: the power of youth voice in ending youth homelessness in the United States

ABSTRACT

Each year, over 600 youth under the age of 25 experience literal homelessness in Austin, Texas. Of these youth, 76% have a history of involvement with foster care or the juvenile justice system—far exceeding the rates of system involvement observed among homeless youth in other large communities in the United States (approximately 54%; Voices of Youth Count, 2017). Recently, Austin was selected by the U.S. Department of Housing & Urban Development as one of ten communities nationwide to participate in the Youth Homelessness Demonstration Program (YHDP), a federal initiative designed to effectively end youth homelessness by 2020. Youth with lived experience are central players in the development and implementation of Austin's response to the youth homelessness crisis. A group of twelve of these youth (the “Austin Youth Collective to End Youth Homelessness,” or AYC) serve as key decision-making partners within the Austin YHDP team. Representatives of the AYC are deeply involved at every level of the community planning process, from the development of youth-centric housing options to system redesign efforts to ensure that youth do not exit the foster care or juvenile justice systems to homelessness. The article provides an overview of the development and contributions of the AYC—including their programmatic recommendations and advocacy work—as well as key recommendations for communities looking to leverage youth voice at the systems level.     

Exploring the half-life of glyphosate in human urine samples

Background

The International Agency for Research on Cancer (IARC) has recently classified glyphosate as a Group 2A ‘probably carcinogenic to humans’. Due to this carcinogenic classification and resulting international debate, there is an increased demand for studies evaluating human health effects from glyphosate exposures. There is currently limited information on human exposures to glyphosate and a paucity of data regarding glyphosate's biological half-life in humans.
