Bridging the Gap between Data and Instruction to Promote School Readiness

States are increasingly endorsing collecting data in the early childhood classroom to measure instructional quality, as well as to enhance classroom- and school-based improvement efforts (Meisels, 2006; National Association for the Education of Young Children, 2009). While an increase in available data has the potential to inform decisions in the classroom, many educators report a need for clearer guidance in analyzing, interpreting, and using the data they collect (Sandall, Schwartz, & Lacroix, 2004; U.S. Department of Education, 2009). Thus, efforts must be made to improve resources and training to provide early childhood educators the opportunity to build their capacity for data proficiency and decision-making within schools. As professionals build their capacity for data-informed decision-making (DIDM), children will benefit from instruction that is responsive to real-time information, and interventions that are tailored to their individual needs

Effects of Daily Zinc, Daily Multiple Micronutrient Powder, or Therapeutic Zinc Supplementation for Diarrhea Prevention on Physical Growth, Anemia, and Micronutrient Status in Rural Laotian Children: A Randomized Controlled Trial.

ObjectivesTo evaluate the optimal zinc supplementation strategy for improving growth and hematologic and micronutrient status in young Laotian children.Study designIn total, 3407 children aged 6-23 months were randomized to receive either daily preventive zinc tablets (7 mg/d), high-zinc, low-iron micronutrient powder (10 mg/d zinc, 6 mg/d iron, and 13 other micronutrients), therapeutic zinc supplementation for diarrhea (20 mg/d for 10 days per episode), or daily placebo powder; all were followed for ~9 months. Anthropometry, hemoglobin, zinc, and iron status were assessed at baseline and endline. Analyses were by intention-to-treat, using linear and modified Poisson regression.ResultsAt baseline, mean (±SD) age was 14.2 ± 5.1 months and stunting and anemia prevalence were 37.9% and 55.6%, respectively. At endline, zinc deficiency in the preventive zinc (50.7%) and micronutrient powder (59.1%) groups were significantly lower than in the therapeutic zinc (79.2%) and control groups (78.6%; P < .001), with no impact on stunting (37.1%-41.3% across the groups, P = .37). The micronutrient powder reduced iron deficiency by 44%-55% compared with other groups (P < .001), with no overall impact on anemia (P = .14). Micronutrient powder tended to reduce anemia by 11%-16% among children who were anemic at baseline (P = .06).ConclusionsDespite improving zinc status, preventive zinc and micronutrient powder had no impact on growth. The micronutrient powder improved iron status and tended to reduce anemia among the subset of previously anemic children.Trial registrationClinicalTrials.govNCT02428647

Are dietary intake and nutritional status influenced by gender? The pattern of dietary intake in Lao PDR:a developing country

BACKGROUND: Recognition of discrepancies between men and women in nutritional intake is important to tackle food and nutrition insecurity and the often-double burden of malnutrition. The purpose of this study was to assess nutritional status and dietary intake of the Lao population, with a focus on possible influences of gender. METHODS: Dietary intake was assessed in a national cross-sectional study of 1771 randomized participants aged from 1.01 to 89 years, using 24-h dietary recall. Dietary reference intakes were used to assess nutrient insufficiency. Chi-square test was used to evaluate gender differences and multiple univariate logistic regression to examine associations between gender, nutritional status, demographics and nutrient insufficiency. RESULTS: Nutrient insufficiencies were higher among pregnant and lactating women than other adult men and women, especially for protein and micronutrients such as vitamin B3, B1, C and other vitamins. Dietary intake and BMI were similar between men and women; all had insufficient intake of all types of nutrients, except sodium. However, women had lower intake than men for almost all nutrients and age groups. The prevalence of overnutrition was higher among those aged 18 years and over for both sexes. Among adult women (15-49.9 years old) and older adult women (50 years old or above), the proportions were: underweight 8.6% (both groups), overweight 18.4 and 20.5%, and obese 34.2 and 39.1%, respectively. Among pregnant and lactating women, the rates of underweight were 7.5 and 1.4%, of overweight were 17.8 and 27.1%, and obese, 21.9 and 40.0%. Among adult and older men, 3.2 and 8.3% were underweight; 21.0 and 18.6% were overweight and 28.2 and 27.6% were obese. Multiple univariate logistic regressions revealed that the factors rural area, dry season and Northern-Lowland region were associated with inadequate micronutrient intake among children, adolescents and adults of both genders. CONCLUSIONS: Dietary intakes were alarmingly micronutrient-insufficient. Macronutrient imbalance and double burden of malnutrition were confirmed in both sexes. Gender differences were limited; men and women had similarly insufficient intakes, but pregnant and lactating women were disproportionately affected. Nutritional interventions should also take men and older people into account to solve nutrition problems

Developing a national health research agenda for Lao PDR:prioritising the research needs of stakeholders

BACKGROUND: Currently the health research system in Lao PDR is fragmented and largely donor led. Capacity among national public health institutes is limited to select priority research questions for funding. OBJECTIVE: The objective of this capacity building and practice-oriented study is to describe the process and outcome of the first National Health Research Agenda for Lao PDR and how the agenda contributes to institutional capacity of the Ministry of Health, in order to contribute to evidence-informed public health policy making. METHOD: This activity used a mixed-methods approach. The overall design is based on principles of the interactive Learning and Action approach and consists out of 6 phases: (1) identification of needs, (2) shared analysis and integration, (3) nation-wide prioritization of research domains, (4) exploring specific research questions, (5) prioritization of research avenues, (6) dialogue and planning for action. The process involved interviews with experts in health policy and research (n = 42), telephone-based survey with district, provincial and national health staff (n = 135), a two-round Delphi consultation with experts in health policy and research (n = 33), and a workshop with policymakers, researchers, international organisations and civil society (n = 45) were held to gather data and conduct shared analysis. RESULTS: 11 research domains were identified and prioritised: Health-seeking behaviour; Health system research; Health service provision; Mother and child health (MCH); Sexual & reproductive health; Health education; Non-communicable diseases (NCDs); Irrational drug use; Communicable diseases (CDs); Road traffic accidents; Mental health. Within these domains over 200 unique research questions were identified. CONCLUSION: Our approach led to a comprehensive, inclusive, public health agenda for Lao PDR to realise better informed health policies. Questions on the agenda are action-oriented, originating in a desire to understand the problem so that immediate improvements can be made. The agenda is used within the MoH as a tool to fund and approve research

Comparison of haemoglobin assessments by HemoCue and two automated haematology analysers in young Laotian children.

BackgroundHaemoglobin (Hb) assessment by Hemocue is used widely for anaemia screening in both adults and children. However, few studies have compared the diagnostic accuracy of Hemocue with an automated haematology analyser in young children.AimTo compare Hb concentrations by Hemocue Hb301 and two automated haematology analysers in young children in rural communities of Lao PDR.MethodsCapillary blood was collected from 6-month-old to 23-month-old children (n=1487) for determination of Hb concentration by Hemocue Hb301. On the same day, venous blood was collected for complete blood count using one of two haematology analysers (XT-1800i, Sysmex, and BC-3000Plus, Mindray Medical International). In a subsample of children (n=129), venous Hb was also measured by HemoCue Hb301. Agreement between the two methods was estimated using Bland-Altman plots.ResultsMean capillary Hb by Hemocue was significantly higher than mean venous Hb by haematology analysers combined (108.4±10.3 g/L vs 102.3±13.1 g/L; P<0.001), resulting in a significantly lower anaemia prevalence (Hb <110 g/L) by Hemocue (53.7% vs 73.9%; P<0.001). The Bland-Altman assessment of agreement showed a bias of 6.1 g/L and limits of agreement were -11.5 g/L to 23.7 g/L. Mean venous Hb concentration by Hemocue Hb301 (113.6±14.0 g/L) was significantly higher than mean capillary Hb concentration by Hemocue Hb301 (110.0±10.7; P=0.03 g/L), which in turn was significantly higher than mean venous Hb concentration by the Mindray BC-3000Plus (102.3±17.4 g/L).ConclusionCapillary and venous Hb concentrations assessed by Hemocue Hb301 showed poor agreement compared with venous Hb by automated haematology analysers, resulting in significantly different anaemia prevalences
