A systematic literature review conducted by a team of researchers from the University of Connecticut, the Hispanic Health Council (Hartford), and the Connecticut Center for Eliminating Health Disparities among Latinos assessed the impact of peer education/counseling on nutrition and health outcomes among Latinos living in the United States.
The results, published in the July/August issue of the Journal of Nutrition Education and Behavior, provide evidence that peer nutrition education has a positive influence on diabetes self-management and breastfeeding outcomes, as well as on general nutrition knowledge and dietary intake behaviors, among Latinos in the US.
“Overall, these nutrition education demonstration studies suggest that peer education has the potential to change dietary behaviors among Latinos,” commented lead investigator Rafael Pérez-Escamilla, PhD. “There is a need to better understand how nutrition peer educators can be formally incorporated into the health care system within the Chronic Care Model community health worker (CHW) framework.” Latinos are the largest minority group in the United States, accounting for more than 12% of the population, and they are expected to be nearly 25% of the population by 2050. Latinos also have less access to nutritionally adequate and safe food—compared to 7.8% of non-Latino white individuals, almost 20% of Latinos are food insecure.
The group’s findings are consistent with studies conducted with non-Latino white and black individuals, which suggests that it is important to formally incorporate peer nutrition educators as part of the CHW framework and to integrate them as part of US public health and clinical health care management. This strategy could contribute to addressing the health disparities that seriously affect Latinos, as well as other minority groups.
Additionally, this review produced the surprising finding that researchers could not identify any experimental or quasi-experimental study assessing the impact of the Food Stamp Nutrition Education Program (FSNE) on Latinos, even though this major program has been in place for over a decade. As many states include peer nutrition educators as part for their FSNE delivery strategies, this represents a major gap in knowledge.
Researchers also found a need for longitudinal randomized trials testing the impact of peer nutrition education interventions for Latinos grounded on goal setting and culturally appropriate behavioral change theories. Operational research is needed to identify the optimal peer educator characteristics, the type of training that they should receive, the client loads and dosage (ie, frequency and amount of contact needed between peer educator and client) and the best educational approaches and delivery settings.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
