This overview of systematic reviews has identified good quality evidence that short course antibiotics are as effective as longer courses for most common infections managed in ambulatory care. The impact on antibiotic resistance and associated treatment failure requires further study.

IntroductionThe extent that the dual burden of undernutrition and overnutrition affects refugee children before resettlement in the US is not well described.ObjectiveTo describe the prevalence of wasting, stunting, overweight, and obesity among refugee children ages 0–10 years at their overseas medical screening examination prior to resettlement in Washington State (WA), and to compare the nutritional status of refugee children with that of low-income children in WA.MethodsWe analyzed anthropometric measurements of 1047 refugee children ages 0–10 years old to assess their nutritional status at the overseas medical screening examination prior to resettlement in WA from July 2012—June 2014. The prevalence estimates of the nutritional status categories were compared by country of origin. In addition, the nutritional status of refugee children age 0–5 years old were compared to that of low-income children in WA from the Center for Disease Control and Prevention’s Pediatric Nutrition Surveillance System.ResultsA total of 982 children were eligible for the study, with the majority (65%) from Somalia, Iraq and Burma. Overall, nearly one-half of all refugee children had at least one form of malnutrition (44.9%). Refugee children ages 0–10 years were affected by wasting (17.3%), stunting (20.1%), overweight (7.6%) and obesity (5.9%). Among children 0–5 years old, refugee children had a significantly higher prevalence of wasting (14.3% versus 1.9%, p<0.001) and stunting (21.3% versus 5.5%, p<0.001), and a lower prevalence of obesity (6.2% versus 12.9%, p<0.001) than low-income children in WA.ConclusionThe dual burden of under- and over-nutrition among incoming refugee children as well as their overall difference in prevalence of nutritional status categories compared to low-income children in WA provides evidence for the importance of tailored interventions to address the nutritional needs of refugee children.

Reducing the burden of stunting in childhood is critical to improving health in low- and middle-income settings. However, because many aetiologies underlie linear growth failure, stunting has proved difficult to prevent and reverse. Understanding the contributions these aetiologies make to the burden of stunting can help the development of targeted, effective interventions. To begin to frame these causes, a qualitative and a quantitative framework of the primary drivers of stunting in low-resource settings were developed. Population attributable fractions (PAF) were estimated to inform the quantitative framework. According to these estimates, infectious diseases were responsible for large attributable fractions in all settings, and a combination of dietary indicators also comprised a large fraction in Africa. However, the PAF calculation was found to have several limitations, including a requirement for a binary outcome and sensitivity to confounding, which necessitate broad interpretation of the results. More robust tools to model complex causality are needed in order to understand the causal aetiology of stunting.
