Maternal and child nutrition services associated with nutritional knowledge and practices, India.

Objective: To evaluate whether maternal and child nutrition activities provided through the Indian Integrated Child Development Services scheme in India were associated with improved nutritional knowledge and practices among beneficiary women. Methods: We used a multistage sampling design to randomly select 4400 pregnant women or mothers of children younger than 2 years for a cross-sectional telephone survey. The respondents were beneficiaries of the scheme from across 11 Indian states. We used multivariate regression models controlling for sociodemographic factors to estimate the association between: scheme activities and nutrition messages heard; and scheme activities and nutrition practices. We also estimated the proportion of the total association with nutrition practices which was mediated by nutrition messages. Results: Among 110 regression models testing unique pairs of seven activities and 18 nutrition messages, 103 showed a statistically significant positive relationship (median risk ratio, RR: 1.14). For activities and nine nutrition practices, 39 out of 54 tested pairs were significantly associated (median RR: 1.16). We observed statistically significant mediation through nutrition messages for 28 out of 42 tested pairs of activities and nutrition practices. Conclusion: Receipt of the scheme's activities was associated with improved nutrition knowledge and practices. Improvements in practices were statistically mediated by improvements in knowledge. These findings suggest that a large-scale nutrition scheme with a strong counselling component could successfully change beneficiary behaviours.

Anemia Etiology in Ethiopia: Assessment of Nutritional, Infectious Disease, and Other Risk Factors in a Population-Based Cross-Sectional Survey of Women, Men, and Children.

BACKGROUND: While the causes of anemia at an individual level (such as certain nutritional deficiencies, infections, and genetic disorders) are well defined, there is limited understanding of the relative burden of anemia attributable to each cause within populations. OBJECTIVES: We sought to estimate the proportion of anemia cases attributable to nutrition, infectious diseases, and other risk factors among women, men, and children in 6 regions of Ethiopia. METHODS: A population-based cross-sectional study was conducted. Data were obtained from 2520 women of reproductive age (15-49 y), 1044 adult men (15-49 y), and 1528 children (6-59 mo). Participants provided venous blood samples for assessment of their hemoglobin concentration; ferritin, folate, vitamin B12, and C-reactive protein levels; and the presence of malaria infection. Stool samples were collected to ascertain the helminth infection status. Sociodemographic questionnaires and a 24-h diet recall were administered. Population-weighted prevalences of anemia and risk factors were calculated. Multivariable-adjusted associations of risk factors with anemia and partial population attributable risk percentages were estimated using generalized linear models. RESULTS: The anemia prevalences were 17% (95% CI: 13%-21%) among women, 8% (95% CI: 6%-12%) among men, and 22% (95% CI: 19%-26%) among children. Low serum ferritin contributed to 11% (95% CI: -1% to 23%) of anemia cases among women, 9% (95% CI: 0%-17%) among men, and 21% (95% CI: 4%-34%) among children. The proportions of anemia attributable to low serum folate were estimated at 25% (95% CI: 5%-41%) among women and 29% (95% CI: 11%-43%) among men. Dietary iron intake was adequate for nearly all participants, while inadequacy was common for folate and vitamin B12. Inflammation and malaria were responsible for less than 1 in 10 anemia cases. CONCLUSIONS: Folate deficiency, iron deficiency, and inflammation appear to be important contributors to anemia in Ethiopia. Folic acid food fortification, targeted iron interventions, and strategies to reduce infections may be considered as potential public health interventions to reduce anemia in Ethiopia.

Assessing public financing for nutrition in Bhutan, Nepal and Sri Lanka.

The objective of this study was to assess public financing for nutrition in Bhutan, Nepal and Sri Lanka to identify limitations of available data and to discuss policy implications. A variant of the Scaling Up Nutrition Movement methodology was used. Budget allocations and expenditures for relevant government ministries during 2012-2018 were identified. Nutrition-related line items were tagged using definitions of nutrition-specific and nutrition-sensitive interventions. Data were aggregated by year and calculated in constant United States dollars (USD). Expenditures by year were presented as a proportion of gross domestic product and general government expenditures. The percent utilization of budget allocations and proportion of funding from central government sources were determined. Per capita expenditures on nutrition-specific interventions varied from USD 1.08-8.76 and for nutrition-sensitive interventions varied from USD 20.22-51.20. Nutrition-specific expenditures as a percent of gross domestic product ranged from 0.08% in Sri Lanka in 2017% to 0.34% in Nepal in 2016. The median utilization rate was 64% for nutrition-specific and 84% for nutrition-sensitive interventions. Nutrition-specific funding financed by the central government was 90.7% in Bhutan and 99.4% in Sri Lanka. This study revealed the need to prioritize and invest in evidence-based interventions, including balancing investments in nutrition-specific versus -sensitive interventions. Challenges in estimation of nutrition expenditures and cross-country comparison were also observed, highlighting the need for appropriate nutrition line item tagging and standardized systems for data collection.

The Global Diet Quality Score is Associated with Higher Nutrient Adequacy, Midupper Arm Circumference, Venous Hemoglobin, and Serum Folate Among Urban and Rural Ethiopian Adults.

BACKGROUND: Nutritionally inadequate diets in Ethiopia contribute to a persisting national burden of adult undernutrition, while the prevalence of noncommunicable diseases (NCDs) is rising. OBJECTIVES: To evaluate performance of a novel Global Diet Quality Score (GDQS) in capturing diet quality outcomes among Ethiopian adults. METHODS: We scored the GDQS and a suite of comparison metrics in secondary analyses of FFQ and 24-hour recall (24HR) data from a population-based cross-sectional survey of nonpregnant, nonlactating women of reproductive age and men (15-49 years) in Addis Ababa and 5 predominately rural regions. We evaluated Spearman correlations between metrics and energy-adjusted nutrient adequacy, and associations between metrics and anthropometric/biomarker outcomes in covariate-adjusted regression models. RESULTS: In the FFQ analysis, correlations between the GDQS and an energy-adjusted aggregate measure of dietary protein, fiber, calcium, iron, zinc, vitamin A, folate, and vitamin B12 adequacy were 0.32 in men and 0.26 in women. GDQS scores were inversely associated with folate deficiency in men and women (GDQS Quintile 5 compared with Quintile 1 OR in women, 0.50; 95% CI: 0.31-0.79); inversely associated with underweight (OR, 0.63; 95% CI: 0.44-0.90), low midupper arm circumference (OR, 0.61; 95% CI: 0.45-0.84), and anemia (OR, 0.59; 95% CI: 0.38-0.91) in women; and positively associated with hypertension in men (OR: 1.77, 95% CI: 1.12-2.80). For comparison, the Minimum Dietary Diversity-Women (MDD-W) was associated more positively (P < 0.05) with overall nutrient adequacy in men and women, but also associated with low ferritin in men, overweight/obesity in women, and hypertension in men and women. In the 24HR analysis (restricted to women), the MDD-W was associated more positively (P < 0.05) with nutrient adequacy than the GDQS, but also associated with low ferritin, while the GDQS was associated inversely with anemia. CONCLUSIONS: The GDQS performed capably in capturing nutrient adequacy-related outcomes in Ethiopian adults. Prospective studies are warranted to assess the GDQS' performance in capturing NCD outcomes in sub-Saharan Africa.

Energy needs in the treatment of uncomplicated severe acute malnutrition: Secondary analysis to optimize delivery of ready-to-use therapeutic foods.

Outpatient therapeutic feeding protocols for the treatment of uncomplicated severe acute malnutrition in children were initially based on weight gain data from inpatient settings and expert knowledge of the physiological requirements during recovery. However, weight gain and energy requirements from historic inpatient settings may differ from modern outpatient settings and therefore may not be appropriate to guide current therapeutic feeding protocols. We calculated the weight gain and average estimated total daily energy requirement of children successfully treated for uncomplicated severe acute malnutrition as outpatients in Niger (n = 790). Mean energy provided by six therapeutic feeding protocols was calculated and compared with average estimated energy requirements in the study population. Overall weight gain was 5.5 g·kg-1 ·day-1 among recovered children. Average energy requirements ranged from 92 to 110 kcal·kg-1 ·day-1 depending on the estimation approach. Two current therapeutic feeding protocols were found to provide an excess of energy after the first week of treatment in our study population, whereas four research protocols tended to provide less energy than the estimated requirement after the first week of treatment. Alternative feeding protocols have the potential to simplify and lead to important savings for programmes but should be evaluated to show adequacy to meet the energy needs of children under treatment, as well as feasibility and cost efficiency. Our findings rely on theoretical calculations based on several assumptions and should be confirmed in field studies.

MUAC as the sole discharge criterion from community-based management of severe acute malnutrition in Burkina Faso.

The use of mid upper arm circumference (MUAC) measurement to screen and determine eligibility for admission to therapeutic feeding programs has been established, but evidence and programmatic experience to inform guidance on the use of MUAC as a discharge criterion is limited. We present results from a large-scale nutritional program using MUAC for admission and discharge and compare program outcomes and response to treatment when determining eligibility for discharge by proportional weight gain versus discharge by MUAC. The study population included all children admitted to the Ministry of Health therapeutic feeding program supported by Médecins Sans Frontières in northern Burkina Faso from September 2007 to December 2011 (n = 50,841). Recovery was high overall using both discharge criteria, with low risks of death, nonresponse, and transfer to inpatient care and high daily gains in weight, MUAC, weight-for-height Z score, and height. When discharge was made by MUAC only, recovery increased, while all adverse program outcomes and length of stay decreased, with increasing MUAC on admission. MUAC-based programming, where MUAC is integrated into program screening, admission, and discharge, is one of several new approaches that can be used to target resources to the most at-risk malnourished children and improve program efficiency and coherency. This analysis provides additional programmatic experience on the use of MUAC-based discharge criterion, but more work may be needed to inform optimal discharge thresholds across settings.

Early childhood development coming of age: science through the life course.

Early childhood development programmes vary in coordination and quality, with inadequate and inequitable access, especially for children younger than 3 years. New estimates, based on proxy measures of stunting and poverty, indicate that 250 million children (43%) younger than 5 years in low-income and middle-income countries are at risk of not reaching their developmental potential. There is therefore an urgent need to increase multisectoral coverage of quality programming that incorporates health, nutrition, security and safety, responsive caregiving, and early learning. Equitable early childhood policies and programmes are crucial for meeting Sustainable Development Goals, and for children to develop the intellectual skills, creativity, and wellbeing required to become healthy and productive adults. In this paper, the first in a three part Series on early childhood development, we examine recent scientific progress and global commitments to early childhood development. Research, programmes, and policies have advanced substantially since 2000, with new neuroscientific evidence linking early adversity and nurturing care with brain development and function throughout the life course.

Stunting in Infancy Is Associated with Decreased Risk of High Body Mass Index for Age at 8 and 12 Years of Age.

BACKGROUND: Effects of early-life stunting on adiposity development later in childhood are not well understood, specifically with respect to age in the onset of overweight and obesity. OBJECTIVES: We analyzed associations of infant stunting with prevalence of, incidence of, and reversion from high body mass index-for-age z score (BMIZ) later in life. We then estimated whether associations of infant stunting with BMIZ varied by sex, indigenous status, and rural or urban residence. METHODS: Data were collected from 1942 Peruvian children in the Young Lives cohort study at ages 1, 5, 8, and 12 y. Multivariable generalized linear models estimated associations of stunting (height-for-age z score <-2) at age 1 y with risk of BMIZ > 1 and BMIZ > 2 prevalence, incidence (moving above a BMIZ threshold between ages), and reversion (moving below a BMIZ threshold between ages) at later ages. RESULTS: After adjustment for covariates, stunting at age 1 y was associated with a lower prevalence of BMIZ > 1 at age 8 y (RR: 0.81; 95% CI: 0.66, 1.00; P = 0.049) and 12 y (RR: 0.75; 95% CI: 0.61, 0.91; P = 0.004), as well as a lower prevalence of BMIZ > 2 at age 8 y. Stunting was not associated with incident risk of BMIZ > 1 or BMIZ > 2. Stunting was positively associated at age 5 y with risk of reversion from BMIZ > 1 (RR: 1.22; 95% CI: 1.05, 1.42; P = 0.008) and BMIZ > 2. We found evidence that the association of stunting with prevalent and incident BMIZ > 1 was stronger for urban children at ages 5 and 8 y, and for nonindigenous children at age 8 y. CONCLUSIONS: Stunting predicted a lower risk of prevalent BMIZ > 1 and BMIZ > 2, even after controlling for potential confounders. This finding may be driven in part by a higher risk of reversion from BMIZ > 1 by age 5 y. Our results contribute to an understanding of how nutritional stunting in infancy is associated with BMIZ later in life.

Participation in the Juntos Conditional Cash Transfer Program in Peru Is Associated with Changes in Child Anthropometric Status but Not Language Development or School Achievement.

BACKGROUND: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of the nutrition transition experienced by many low- and middle-income countries. OBJECTIVE: We estimated the association of participation in Peru's Juntos CCT with anthropometry, language development, and school achievement among children aged 7-8 y. METHODS: We used data from the Young Lives Study of a cohort born between 2001 and 2002. We estimated associations of the Juntos program with height-for-age z score (HAZ), body mass index-for-age z score (BAZ), stunting, and overweight at age 7-8 y separately for children participating in the program for ≥2 y (n = 169) and children participating for <2 y (n = 188). We then estimated associations with receptive vocabulary and grade achievement among children who had been assessed at age 4-6 y before enrollment in Juntos (n = 243). We identified control subjects using propensity score matching and conducted difference-in-differences comparisons. RESULTS: Juntos participation was associated with increases in HAZ among boys participating for ≥2 y [average effect of treatment among the treated (ATT): 0.43; 95% CI: 0.09, 0.77; P = 0.01] and for boys participating for <2 y (ATT: 0.52; 95% CI: 0.23, 0.80; P < 0.01). Among girls participating in the program for ≥2 y, BAZ declined (ATT: -0.60; 95% CI: -1.00, -0.21; P < 0.01) as did the prevalence of overweight (ATT: -22.0 percentage points; 95% CI: -42.5, -2.7 percentage points; P = 0.03). We observed no significant associations of Juntos participation with receptive vocabulary or grade attainment. CONCLUSIONS: CCT program participation in Peru was associated with better linear growth among boys and decreased BAZ among girls, highlighting that a large-scale poverty-alleviation intervention may influence anthropometric outcomes in the context of the nutrition transition.

No global consensus: a cross-sectional survey of maternal weight policies.

BACKGROUND: Growing evidence suggests that maternal prepregnancy weight and gestational weight gain are risk factors for perinatal complications and subsequent maternal and child health. Postpartum weight retention is also associated with adverse birth outcomes and maternal obesity. Clinical guidelines addressing healthy weight before, during, and after pregnancy have been introduced in some countries, but at present a systematic accounting for these policies has not been conducted. The objective of the present study was to conduct a cross-national comparison of maternal weight guidelines. METHODS: This cross sectional survey administered a questionnaire online to key informants with expertise on the subject of maternal weight to assess the presence and content of preconceptional, pregnancy and postpartum maternal weight guidelines, their rationale and availability. We searched 195 countries, identified potential informants in 80 and received surveys representing 66 countries. We estimated the proportion of countries with guidelines by region, income, and formal or informal policy, and described and compared guideline content, including a rubric to assess presence or absence of 4 guidelines: encourage healthy preconceptional weight, antenatal weighing, encourage appropriate gestational gain, and encourage attainment of healthy postpartum weight. RESULTS: Fifty-three countries reported either a formal or informal policy regarding maternal weight. The majority of these policies included guidelines to assess maternal weight at the first prenatal visit (90%), to monitor gestational weight gain during pregnancy (81%), and to provide recommendations to women about healthy gestational weight gain (62%). Guidelines related to preconceptional (42%) and postpartum (13%) weight were less common. Only 8% of countries reported policies that included all 4 fundamental guidelines. Guideline content and rationale varied considerably between countries, and respondents perceived that within their country, policies were not widely known. CONCLUSIONS: These results suggest that maternal weight is a concern throughout the world. However, we found a lack of international consensus on the content of guidelines. Further research is needed to understand which recommendations or interventions work best with respect to maternal weight in different country settings, and how pregnancy weight policies impact clinical practices and health outcomes for the mother and child.

Oral iron supplementation and anaemia in children according to schedule, duration, dose and cosupplementation: a systematic review and meta-analysis of 129 randomised trials.

INTRODUCTION: WHO guidelines on iron supplementation among children call for further research to identify the optimal schedule, duration, dose and cosupplementation regimen. METHODS: A systematic review and meta-analysis of randomised controlled trials was undertaken. Randomised controlled trials providing ≥30 days of oral iron supplementation versus placebo or control to children and adolescents aged <20 years were eligible. Random-effects meta-analysis was used to summarise the potential benefits and harms of iron supplementation. Meta-regression was used to estimate iron effect heterogeneity. RESULTS: 129 trials with 201 intervention arms randomised 34 564 children. Frequent (3-7/week) and intermittent (1-2/week) iron regimens were similarly effective at decreasing anaemia, iron deficiency and iron deficiency anaemia (p heterogeneity >0.05), although serum ferritin levels and (after adjustment for baseline anaemia) haemoglobin levels increased more with frequent supplementation. Shorter (1-3 months) versus longer (7+ months) durations of supplementation generally showed similar benefits after controlling for baseline anaemia status, except for ferritin which increased more with longer duration of supplementation (p=0.04). Moderate-dose and high-dose supplements were more effective than low-dose supplements at improving haemoglobin (p=0.004), ferritin (p=0.008) and iron deficiency anaemia (p=0.02), but had similar effects to low-dose supplements for overall anaemia. Iron supplementation provided similar benefits when administered alone or in combination with zinc or vitamin A, except for an attenuated effect on overall anaemia when iron was cosupplemented with zinc (p=0.048). CONCLUSIONS: Weekly and shorter duration iron supplementation at moderate or high doses might be optimal approaches for children and adolescents at risk of deficiency. TRIAL REGISTRATION NUMBER: CRD42016039948.

Iron supplementation and paediatric HIV disease progression: a cohort study among children receiving routine HIV care in Dar es Salaam, Tanzania.

BACKGROUND: Anaemia is common among HIV-infected children and iron supplementation is prescribed routinely for the prevention and management of anaemia among children. Limited evidence suggests iron supplementation may have adverse effects among HIV-infected populations. We aimed to estimate the effect of iron supplement use on mortality, disease progression and haematological outcomes among HIV-infected children in Dar es Salaam, Tanzania. METHODS: A prospective cohort study was conducted among HIV-infected children (aged 0-14 years) receiving antiretroviral treatment or supportive care between October 2004 and September 2014. Clinical data were recorded on morbidity and vital status, haematological status and prescriptions at each clinical visit. Cox proportional hazards models adjusted for time-varying covariates were used to estimate the association of time-varying iron supplementation on the hazard rate of mortality, HIV disease stage progression, tuberculosis incidence and anaemia and microcytosis persistence. RESULTS: In all, 4229 children were observed during 149 260 clinic visits for a mean follow-up of 2.9 years. After adjustment for time-varying clinical covariates, time-varying iron supplementation was associated with a 2.87 times higher hazard rate of mortality (95% CI: 1.70, 4.87) and a 1.48 times higher hazard rate of HIV disease stage progression (95% CI: 1.10, 1.98). Iron supplementation was also associated with a lower rate of anaemia persistence (HR = 0.47; 95% CI: 0.37, 0.61). No differences in the association between iron supplementation and clinical outcomes were observed by antiretroviral therapy or anaemia status. CONCLUSIONS: Iron supplementation may increase the risk of HIV disease stage progression and mortality among HIV-infected children, while reducing the risk of anaemia.

Risk of community- and hospital-acquired bacteremia and profile of antibiotic resistance in children hospitalized with severe acute malnutrition in Niger.

OBJECTIVE: To estimate the prevalence and antibiotic resistance profile of community- and hospital-acquired bacteremia among hospitalized children with severe acute malnutrition in Niger. METHODS: A descriptive, longitudinal study was conducted in an intensive nutritional rehabilitation center in Madarounfa, Niger. Children aged 6 to 59 months admitted for inpatient treatment of complicated severe acute malnutrition (n=2187) had blood specimens drawn at admission to assess prevalence of community-acquired bacteremia. Subsequent specimens were drawn per physician discretion to assess incidence of hospital-acquired bacteremia. Antibiotic susceptibility testing was performed on positive blood cultures. RESULTS: The prevalence of community-acquired bacteremia at admission was at least 9.1% (95% confidence interval [CI]: 8.1, 10.4%), with non-typhoid Salmonella identified in over half (57.8%) of cases. The cumulative incidence of hospital-acquired bacteremia was estimated at 1.2% (95% CI: 0.8, 1.7%), among which the most common organisms were Klebsiella pneumoniae (19.4%), Acinetobacter baumannii (16.1%), Enterococcus faecalis (12.9%), and Escherichia coli (12.9%). In community-acquired bacteremia, 58% cases were resistant to amoxicillin-clavulanate; 100% of hospital-acquired bacteremia cases were resistant to amoxicillin and amoxicillin-clavulanate. Mortality risk was elevated among children with hospital-acquired bacteremia (risk ratio [RR] = 9.32) and community-acquired bacteremia (RR = 2.67). CONCLUSION: Bacteremia was a significant contributor to mortality. Antibiotic resistance poses a challenge to effective clinical management of severe acute malnutrition.

Improving health service delivery in conflict-affected settings: Lessons from a nationwide strategic purchasing mechanism in Afghanistan.

BACKGROUND: Due to ongoing insecurity, the government of Afghanistan delivers health care to the country's population by contracting out service delivery to non-governmental organization service providers (SPs). In 2018, major changes to SP contracts were introduced, resulting in a new pay-for-performance service delivery model. This model, called "Sehatmandi", pays SPs based on the volume of 11 key services they provide. METHODS: A narrative review of Sehatmandi's key features is presented, as well as lessons learned during implementation. Counterfactual comparisons of service delivery data for 10 payment-related service indicators are made. The first comparison is between the rate of change in the volume of services delivered from 2018 to 2019 (ie, the first year of Sehatmandi implementation) relative to the rate change from 2017 to 2018 (ie, prior to the program). The second comparison is between the rate of change in the volume of services delivered in provinces under the pay-for-performance mechanism relative to provinces which were not financed using pay-for-performance. Time trends in non-payment service indicators and service quality are also examined. RESULTS: The increase in service volume in Sehatmandi provinces from 2018 to 2019 was higher than the increase from 2017 to 2018 for 8 out of 10 indicators. The median increase in the rate of change was 10 percentage points. Similar results were obtained when comparing pay-for-performance provinces to those not financed using pay-for-performance. Improvements were also observed for services that were not directly compensated by the pay-for-performance approach. Payment for service volume was not associated with reduced service quality. The narrative review suggests that the pay-for-performance system has stimulated more effective oversight of SPs by the government of Afghanistan and has incentivized innovative service delivery strategies by SPs. Sehatmandi may benefit from re-structuring its financial incentives to stimulate improved service quality and accelerate delivery of lagging services. CONCLUSIONS: The available evidence - though subject to some limitations - suggests that the introduction of a pay-for-performance system was associated with an expanded volume of service delivery in Afghanistan. This approach may be beneficial in other conflict-affected countries.

Improving estimates of the burden of severe wasting: analysis of secondary prevalence and incidence data from 352 sites.

INTRODUCTION: Estimates of incident cases of severe wasting among young children are not available for most settings but are needed for optimal planning of treatment programmes and burden estimation. To improve programme planning, global guidance recommends a single 'incidence correction factor' of 1.6 be applied to available prevalence estimates to account for incident cases. This study aimed to update estimates of the incidence correction factor to improve programme planning and inform the approach to burden estimation for severe wasting. METHODS: A global call was issued for secondary data from severe wasting treatment programmes including prevalence, population size, programme admission and programme coverage through a UNICEF-led effort. Site-specific incidence correction factors were calculated as the number of incident cases (annual programme admissions/programme coverage) divided by the number of prevalent cases (prevalence*population size). Estimates were aggregated by country, region and overall using inverse-variance weighted random-effects meta-analysis. RESULTS: We estimated incidence correction factors from 352 sites in 20 countries. Estimates aggregated by country ranged from 1.3 (Nigeria) to 30.1 (Burundi). Excluding implausible values, the overall incidence correction factor was 3.6 (95% CI 3.4 to 3.9). CONCLUSION: Our results suggest that incidence correction factors vary between sites and that the burden of severe wasting will often be underestimated using the currently recommended incidence correction factor of 1.6. Application of updated incidence correction factors represents a simple way to improve programme planning when incidence data are not available and could inform the approach to burden estimation.

The Global Cohort of Doctoral Students: Building Shared Global Health Research Capacity in High-Income and Low- and Middle-Income Countries.

Doctoral students in high- and low-income countries pursuing careers in global health face gaps in their training that could be readily filled through structured peer-learning activities with students based at partnering institutions in complimentary settings. We share lessons learned from the Global Cohort of Doctoral Students, a community of doctoral students based at the Harvard T. H. Chan School of Public Health, Haramaya University, University of Gondar, University of Botswana, and University of Rwanda College of Medicine and Health Sciences. Students in the Global Cohort program engage in collaborative research, forums for constructive feedback, and professional development activities. We describe the motivation for the program, core activities, and early successes.

Anemia, Iron Status, and HIV: A Systematic Review of the Evidence.

People living with HIV (PLWHIV) are at high risk of anemia due to inadequate iron intake, HIV and opportunistic infections, and inflammation, and as a side effect of antiretroviral therapy. Though iron supplementation can reduce iron deficiency anemia (IDA) in the general population, its role in anemia and in the health of PLWHIV is unclear due to concerns that iron supplementation may increase HIV replication and risk of opportunistic infections. We systematically reviewed the evidence on indicators of iron status, iron intake, and clinical outcomes among adults and children with HIV. The evidence suggests that anemia is associated with an increased risk of all-cause mortality and incident tuberculosis among HIV-infected individuals, regardless of anemia type, and the magnitude of the risk is greater with more severe anemia. High serum ferritin is associated with adverse clinical outcomes, although it is unclear if this is due to high iron or inflammation from disease progression. One large observational study found an increased risk of all-cause mortality among HIV-infected adults if they received iron supplementation. Published randomized controlled trials of iron supplementation among PLWHIV tend to have small sample sizes and have been inconclusive in terms of effectiveness and safety. Large randomized trials exploring approaches to safely and effectively provide iron supplementation to PLWHIV are warranted.

Determinants of Patient Delay in Diagnosis of Pulmonary Tuberculosis in Somali Pastoralist Setting of Ethiopia: A Matched Case-Control Study.

Background: Healthcare-seeking behavior is the basis to ensure early diagnosis and treatment of tuberculosis (TB) in settings where most cases are diagnosed upon self-presentation to health facilities. Yet, many patients seek delayed healthcare. Thus, we aimed to identify the determinants of patient delay in diagnosis of pulmonary TB in Somali pastoralist area, Ethiopia. Methods: A matched case-control study was conducted between December 2017 and October 2018. Cases were self-presented and newly diagnosed pulmonary TB patients aged ≥ 15 years who delayed > 30 days without healthcare provider consultation, and controls were patients with similar inclusion criteria but who consulted a healthcare provider within 30 days of illness; 216 cases sex-matched with 226 controls were interviewed using a pre-tested questionnaire. Hierarchical analysis was done using conditional logistic regression. Results: After multilevel analysis, pastoralism, rural residence, poor knowledge of TB symptoms and expectation of self-healing were individual-related determinants. Mild-disease and manifesting a single symptom were disease-related, and >1 h walking distance to nearest facility and care-seeking from traditional/religious healers were health system-related determinants of patient delay > 30 days [p < 0.05]. Conclusion: Expansion of TB services, mobile screening services, and arming community figures to identify and link presumptive cases can be effective strategies to improve case detection in pastoral settings.
