Background: Middle childhood and adolescence are critical times for the growth, development, and establishment of healthy eating habits. The Europe and Central Asia (ECA) region has been through economic and nutrition transitions over the past 20 years, which are likely to have affected the nutritional status of this group. Objective: This review aimed to collate data on the nutritional status and dietary patterns of school-aged children (SAC) and adolescents (5-19 years) across the ECA region in order to inform policy and programming decisions. Methods: A systematic search of the literature in Pubmed, Cochrane, and ScienceDirect databases was conducted (April 2019), complemented by a systematic review of nationally representative surveys. Inclusion criteria were any data on micronutrient deficiencies, overweight, stunting, wasting, thinness, or dietary patterns in SAC and adolescents in the 21 UNICEF-defined countries of ECA, published since the year 2000. Results: Results included 134 published papers and 6 sources of survey data. The majority of studies were conducted in Turkey (56%), with all other countries having fewer than 10 studies each; 8 countries in the region having no studies on this age group at all. The most significant nutrition issue was overweight and obesity. Micronutrient deficiencies, particularly anemia, emerge as a further challenge. Dietary patterns were worse in urban areas and boys. Conclusions: The findings of this review suggest that there are 3 critical areas that need immediate attention: the promotion of healthy diets and physical activity to address high levels of overweight/obesity, anemia prevention efforts, and addressing the considerable data gaps for SAC and adolescent nutrition.

Recognizing the multiple interacting layers of pedagogical content knowledge, in this article, we present the findings from a study that examined the extent to which participation in case-based instruction about self-generated visual representations (VRs) supported special education pre-service teachers ( N = 25) in enhancing their (a) knowledge of VRs, specifically what and how to teach, as a strategy for solving mathematics problems, and (b) applied instructional practices, specifically analysis of student knowledge and instructional planning, about VRs for students with disabilities (SWDs) to solve mathematics problems. The data revealed that case-based instruction about VRs in a special education mathematics methods course enriched pre-service teachers personal understanding about VRs and their ability to target SWDs learning needs regarding VRs. Implications for pre-service teacher preparation and research are provided.

Background Community health workers (CHWs) perform a range of important tasks; however, limited evidence is available regarding the association between their workload and the quality of care they provide. Objective To analyze the quality of preventive and curative care provided by two groups of CHWs with different workloads in southern Bangladesh. Methods One group of CHWs provided preventive care in addition to implementing community case management (CCM) of acute respiratory infection and diarrhea, and another group additionally treated severe acute malnutrition (SAM). Preventive care was measured by case management observation at a routine household visit. Curative care was measured by case scenarios. Qualitative methods were used to contextualize CHWs' performance by examining their perceptions of challenges related to their workload. A total of 338 CHWs were assessed. Results CHWs managing cases of SAM worked significantly more hours than the other group (16.7 ± 6.9 hours compared with 13.3 ± 4.6 hours weekly, p < .001) but maintained quality of care on curative and preventive work tasks. Effectively treating cases of SAM appeared to motivate CHWs. Conclusions This was one of the first trials adding the treatment of SAM to a CHW workload and suggests that adding SAM to a well-trained and supervised CHW's workload, including preventive and curative tasks, does not necessarily yield lower quality of care. However, increased workloads had consequences for CHWs' domestic life, and further increases in workload may not be possible without additional incentives.
