RESUMO

Childhood stunting remains a public health burden worldwide. Although many studies have examined early life and in-utero risk factors; most have been observational and have used analytic techniques that make inferences limited to population means, thereby obscuring important within-group variations. This study addressed that important gap. Using data from a birth cohort of Ugandan infants (n = 4528), we applied group-based trajectory modelling to assess diverse patterns of growth among children from birth to 1-year old. A multinomial regression model was conducted to understand the relationship between risk factors and observed patterns across groups. We found that the onset of stunting occurred before birth and followed four distinct growth patterns: chronically stunted (Group 1), recovery (Group 2), borderline stunted (Group 3) and normal (Group 4). The average length-for-age z-score (LAZ) at birth was -2.6, -3.9, -0.6 and 0.5 for Groups 1-4, respectively. Although both Groups 1 and 2 were stunted at birth, stunting persisted in Group 1 while children in Group 2 recovered by the fourth month. Group 3 exhibited mild stunting while Group 4 was normal. Wasting and underweight were observed in all groups, with the highest prevalence of underweight in Group 1. Wasting gradually increased among children born already stunted (Groups 1 and 2). This showed the importance of distinguishing children by their growth patterns rather than aggregating them and only comparing population averages against global growth standards. The design of nutrition interventions should consider the differential factors and potential for growth gains relative to different risks within each group.

RESUMO

Despite data suggesting that older adolescence is an important period of risk for HIV acquisition in Uganda, tailored HIV prevention programming is lacking. To address this gap, we developed and tested nationally, InThistoGether (ITG), a text messaging-based HIV prevention program for 18-22 year-old Ugandan youth. To assess feasibility and acceptability, and preliminary indications of behavior change, a randomized controlled trial was conducted with 202 youth. Participants were assigned either to ITG or an attention-matched control group that promoted general health (e.g., self-esteem). They were recruited between December 2017 and April 2018 on Facebook and Instagram, and enrolled over the telephone. Between 5-10 text messages were sent daily for seven weeks. Twelve weeks later, the intervention ended with a one-week 'booster' that reviewed the main program topics. Measures were assessed at baseline and intervention end, 5 months post-randomization. Results suggest that ITG is feasible: The retention rate was 83%. Ratings for the content and program features met acceptability thresholds; program experience ratings were mixed. ITG also was associated with significantly higher rates of condom-protected sex (aIRR = 1.68, p < 0.001) and odds of HIV testing (aOR = 2.41, p = 0.03) compared to the control group. The odds of abstinence were similar by experimental arm however (aOR = 1.08, p = 0.86). Together, these data suggest reason for optimism that older adolescent Ugandans are willing to engage in an intensive, text messaging-based HIV prevention programming. Given its wide reach and low cost, text messaging should be better utilized as an intervention delivery tool in low-income settings like Uganda. Findings also suggest that ITG may be associated with behavior change in the short-term. (Trial registration: ClinicalTrials.gov ID# NCT02729337).


RESUMEN: A pesar de que los datos sugieren que la adolescencia mayor es un período importante de riesgo de contraer el VIH en Uganda, hace falta una programación de prevención del VIH personalizados. Para abordar esta brecha, desarrollamos y probamos a nivel nacional, InThistoGether (ITG), un programa de prevención del VIH basado en mensajes de texto para jóvenes ugandeses de 18 a 22 años. Para evaluar la viabilidad y aceptabilidad, y las indicaciones preliminares del cambio de comportamiento, se realizó un ensayo controlado aleatorio con 202 jóvenes. Los participantes fueron asignados a ITG o a un grupo de control de atención que promovía la salud general (p.ej., la autoestima). Fueron reclutados entre diciembre de 2017 y abril de 2018 en Facebook e Instagram y se inscribieron por teléfono. Se enviaron entre 5 y 10 mensajes de texto diariamente durante siete semanas. Doce semanas después, la intervención terminó con un "refuerzo" de una semana que repasó los principales temas del programa. Las medidas se evaluaron al inicio y al final de la intervención, 5 meses después de la aleatorización. Los resultados sugieren que ITG es factible: la tasa de retención fue 83%. Las calificaciones del contenido y las características del programa alcanzaron los umbrales de aceptabilidad; las calificaciones de experiencia del programa fueron mixtas. La ITG también se asoció con tasas significativamente más altas de relaciones sexuales protegidas con condón (aIRR = 1.68, p < 0.001) y probabilidades de pruebas de VIH (aOR = 2.41, p = 0.03) en comparación con el grupo de control. Sin embargo, las probabilidades de abstinencia fueron similares en el grupo experimental (ORa = 1,08, p = 0,86). Juntos, estos datos sugieren razones para el optimismo de que los adolescentes ugandeses mayores están dispuestos a participar en un programa intensivo de prevención del VIH basado en mensajes de texto. Dado su amplio alcance y bajo costo, los mensajes de texto deberían utilizarse como una herramienta de entrega de intervenciones en lugares de bajos ingresos como Uganda. Los hallazgos también sugieren que ITG puede estar asociada con cambios de comportamiento a corto plazo.

RESUMO

Growth faltering in early childhood is prevalent in many low resource countries. Poor maternal dietary diversity during pregnancy has been linked with increased risk of fetal growth failure and adverse birth outcomes but may also influence subsequent infant growth. Our aim is to assess the role of prenatal maternal dietary diversity in infant growth in rural Uganda. Data from 3291 women and infant pairs enrolled in a birth cohort from 2014 to 2016 were analysed (NCT04233944). Maternal diets were assessed using dietary recall in the second or third trimesters of pregnancy. Maternal dietary diversity scores (DDS) were calculated using the FAO Minimum Dietary Diversity for Women (MDD-W). Cox regression models were used to evaluate associations of the DDS with the incidence of underweight, stunting and wasting in infants from 3 to 12 months, adjusting for confounding factors. The median DDS for women was low, at 3.0 (interquartile range 3.0-4.0), relative to the threshold of consuming five or more food groups daily. Infants of women in highest quartile of DDS (diverse diets) were less likely to be underweight (adjusted hazard ratio: 0.70, 95% confidence interval: 0.61, 0.80) compared with infants of women in Quartile 1 (p for trend <0.001) in models controlling for maternal factors. There was no significant association between DDS and stunting or wasting. Our findings suggest a relationship between higher maternal dietary diversity and lower risk of underweight in infancy. These findings suggest that programmes to improve infant growth could additionally consider strengthening prenatal dietary diversity to improve child outcomes globally.

RESUMO

BACKGROUND: Approximately 20.5 million infants were born weighing <2500 g (defined as low birthweight or LBW) in 2015, primarily in low- and middle-income countries (LMICs). Infants born LBW, including those born preterm (<37 weeks gestation), are at increased risk for numerous consequences, including neonatal mortality and morbidity as well as suboptimal health and nutritional status later in life. The objective of this study was to identify predictors of LBW and preterm birth among infants in rural Uganda. METHODS: Data were derived from a prospective birth cohort study conducted from 2014-2016 in 12 districts across northern and southwestern Uganda. Birth weights were measured in triplicate to the nearest 0.1 kg by trained enumerators within 72 hours of delivery. Gestational age was calculated from the first day of last menstrual period (LMP). Associations between household, maternal, and infant characteristics and birth outcomes (LBW and preterm birth) were assessed using bivariate and multivariable logistic regression with stepwise, backward selection analyses. RESULTS: Among infants in the study, 4.3% were born LBW (143/3,337), and 19.4% were born preterm (744/3,841). In multivariable analysis, mothers who were taller (>150 cm) (adjusted Odds Ratio (aOR) = 0.42 (95% CI = 0.24, 0.72)), multigravida (aOR = 0.62 (95% CI = 0.39, 0.97)), or with adequate birth spacing (>24 months) (aOR = 0.60 (95% CI = 0.39, 0.92)) had lower odds of delivering a LBW infant Mothers with severe household food insecurity (aOR = 1.84 (95% CI = 1.22, 2.79)) or who tested positive for malaria during pregnancy (aOR = 2.06 (95% CI = 1.10, 3.85)) had higher odds of delivering a LBW infant. In addition, in multivariable analysis, mothers who resided in the Southwest (aOR = 0.64 (95% CI = 0.54, 0.76)), were ≥20 years old (aOR = 0.76 (95% CI = 0.61, 0.94)), with adequate birth spacing (aOR = 0.76 (95% CI = 0.63, 0.93)), or attended ≥4 antenatal care (ANC) visits (aOR = 0.56 (95% CI = 0.47, 0.67)) had lower odds of delivering a preterm infant; mothers who were neither married nor cohabitating (aOR = 1.42 (95% CI = 1.00, 2.00)) or delivered at home (aOR = 1.25 (95% CI = 1.04, 1.51)) had higher odds. CONCLUSIONS: In rural Uganda, severe household food insecurity, adolescent pregnancy, inadequate birth spacing, malaria infection, suboptimal ANC attendance, and home delivery represent modifiable risk factors associated with higher rates of LBW and/or preterm birth. Future studies on interventions to address these risk factors may be warranted.

RESUMO

BACKGROUND: Uganda's maternal mortality remains unacceptably high, with thousands of women and newborns still dying of preventable deaths from pregnancy and childbirth-related complications. Globally, Antenatal care (ANC) attendance has been associated with improved rates of skilled births. However, despite the fact that over 95% of women in Uganda attend at least one ANC, over 30% of women still deliver at home alone, or in the presence of an unskilled birth attendant, with many choosing to come to hospital after experiencing a complication. We explored barriers to women's decisions to deliver in a health care facility among postpartum women in rural southwestern Uganda, to ultimately inform interventions aimed at improving skilled facility births. METHODS: Between December 2018 and March 2019, we conducted in-depth qualitative face-to-face interviews with 30 post-partum women in rural southwestern Uganda. The purposeful sample was intended to represent women with differing experiences of pregnancy, delivery, and antenatal care. We included 15 adult women who had delivered from their homes and 15 who had delivered from a health facility in the previous 3 months. Women were recruited from 10 villages within 20 km of a regional referral hospital. Interviews were conducted and digitally recorded in a private setting by a trained native speaker to elicit experiences of pregnancy and birth. Translated transcripts were generated and coded. Coded data were iteratively reviewed and sorted to derive descriptive categories using an inductive content analytic approach. RESULTS: Regardless of where they decided to give birth, women wished to deliver in a supportive, respectful, responsive and loving environment. The data revealed six key barriers to women's decisions to deliver from a health care facility: 1) Fear of unresponsive care, fueling a fear of being neglected or abandoned while at the facility; 2) fear of embarrassment and mistreatment by health care providers; 3) low perception of risk associated with pregnancy and childbirth; 4) preferences for particular birthing positions and their outcome expectations; 5) perceived lack of privacy in public facilities; and 6) perceived poor clinical and interpersonal skills of health providers to adequately explain birthing procedures or support expectant or laboring women and their newborn. CONCLUSION: Anticipation of unsupportive, unresponsive, disrespectful treatment, and a perceived lack of tolerance for simple, non-harmful traditions prevent women from delivering at health facilities. Building better interpersonal relationships between patients and providers within health systems could reinforce trust, improve patient-provider interaction, and facilitate useful information transfer during ANC and delivery visits. These expectations are important considerations in developing supportive health care systems that provide acceptable patient-friendly care. These findings are indicative of the vital need for midwives and other health care providers to have additional training in the role of communication and dignity in delivery of quality health care.

RESUMO

BACKGROUND: Utilization of perinatal services in Uganda remains low, with correspondingly high rates of unskilled home deliveries, which can be life-threatening. We explored psychosocial and cultural factors influencing birthing choices for unskilled home delivery among postpartum women in rural southwestern Uganda. METHODS: We conducted in-depth qualitative face-to-face interviews with 30 purposively selected women between December 2018 and March 2019 to include adult women who delivered from their homes and health facility within the past three months. Women were recruited from 10 villages within 20 km from a referral hospital. Using the constructs of the Health Utilization Model (HUM), interview topics were developed. Interviews were conducted and digitally recorded in a private setting by a native speaker to elicit choices and experiences during pregnancy and childbirth. Translated transcripts were generated and coded. Coded data were iteratively reviewed and sorted to derive categories using inductive content analytic approach. RESULTS: Eighteen women (60%) preferred to deliver from home. Women's referent birth location was largely intentional. Overall, the data suggest women choose home delivery (1) because of their financial dependency and expectation for a "natural" and normal childbirth, affecting their ability and need to seek skilled facility delivery; (2) as a means of controlling their own birth processes; (3) out of dissatisfaction with facility-based care; (4) out of strong belief in fate regarding birth outcomes; (5) because they have access to alternative sources of birthing help within their communities, perceived as "affordable," "supportive," and "convenient"; and (6) as a result of existing gender and traditional norms that limit their ability and freedom to make family or health decisions as women. CONCLUSION: Women's psychosocial and cultural understandings of pregnancy and child birth, their established traditions, birth expectations, and perceptions of control, need, and quality of maternity care at a particular birthing location influenced their past and future decisions to pursue home delivery. Interventions to address barriers to healthcare utilization through a multipronged approach could help to debunk misconceptions, increase perceived need, and motivate women to seek facility delivery.

RESUMO

BACKGROUND: Environmental enteric dysfunction (EED), characterized by altered intestinal permeability/inflammation, microbial translocation, and systemic inflammation (SI), may be a significant contributor to micronutrient deficiencies and poor growth in infants from low-resource settings. OBJECTIVE: We examined associations among EED, SI, growth, and iron status at 6 mo of age. METHODS: We performed a cross-sectional analysis of 6-mo-old infants (n = 548) enrolled in a Ugandan birth-cohort study (NCT04233944). EED was assessed via serum concentrations of anti-flagellin and anti- LPS immunoglobulins (Igs); SI was assessed via serum concentrations of ɑ1-acid glycoprotein (AGP) and C-reactive protein (CRP); iron status was assessed via serum concentrations of hemoglobin (Hb), soluble transferrin receptor (sTfR), and ferritin. Associations were assessed using adjusted linear regression analysis. RESULTS: At 6 mo, ∼35% of infants were stunted [length-for-age z score (LAZ) < -2] and ∼53% were anemic [hemoglobin (Hb) <11.0 g/dL]. Nearly half (∼46%) had elevated AGP (>1 g/L) and ∼30% had elevated CRP (>5 mg/L). EED and SI biomarkers were significantly correlated (r = 0.142-0.193, P < 0.001 for all). In adjusted linear regression models, which included adjustments for SI, higher anti-flagellin IgA, anti-LPS IgA, and anti-LPS IgG concentrations were each significantly associated with lower LAZ [ß (95% CI): -0.21 (-0.41, 0.00), -0.23 (-0.44, -0.03), and -0.33 (-0.58, -0.09)]. Furthermore, higher anti-flagellin IgA, anti-flagellin IgG, and anti-LPS IgA concentrations were significantly associated with lower Hb [ß (95% CI): -0.24 (-0.45, -0.02), -0.58 (-1.13, 0.00), and -0.26 (-0.51, 0.00)] and higher anti-flagellin IgG and anti-LPS IgG concentrations were significantly associated with higher sTfR [ß (95% CI): 2.31 (0.34, 4.28) and 3.13 (0.75, 5.51)]. CONCLUSIONS: EED is associated with both low LAZ and iron status in 6-mo-old infants. Further research on the mechanisms by which EED affects growth and micronutrient status is warranted.

RESUMO

In Uganda, HIV prevention programming for older adolescents is noticeably lacking, even though HIV incidence rates increase dramatically from adolescence into young adulthood. Here we describe the development of In This toGether (ITG), the first-of-its-kind, comprehensive text messaging-based HIV prevention program for both sexually active and abstinent 18- to 22-year-old Ugandans. Five iterative development activities are described: (1) conducting focus groups (FGs) to better understand the sexual decision-making of older adolescents across Uganda and to gain 'voice' of older adolescents; (2) the drafting of intervention content based on FG data; (3) testing of the drafted content with two Content Advisory Teams (CATs) that reviewed and provided feedback on the messages; (4) alpha-testing the program among the research team; and (5) beta-testing the intervention and protocol with people in the target population. Participants were recruitment nationally via Facebook and Instagram, and enrolled over the telephone by research staff. Results suggest that men were easier to reach and engage across all intervention development steps. As such, specific efforts to enroll women were made to ensure that feedback from both sexes was taken into account. FG participants said they were interested in learning more about sexual positions, how to prepare for sex, the consequences of unprotected sex, benefits of protected sex, masturbation, and how to be a good sexual partner. In both the FGs (n = 202) and CATs (n = 143) however, some noted that masturbation, oral sex, and anal sex were particularly sensitive topics. These messages were rewritten to address the cultural sensitivity. Feedback from beta test participants (n = 34) suggested that text messaging-based HIV prevention programming that is intense (e.g., 5-11 messages per day) and extends for two months, is both feasible and acceptable. In conclusion, the engagement of older adolescents at each step of the iterative intervention development process increased the likelihood that the final product would resonate with 18- to 22-year-old Ugandan youth across the country. Furthermore, social media appears to be a feasible method for recruiting national samples of Ugandan older adolescents into HIV-focused research.

RESUMO

Aflatoxins are toxic metabolites of Aspergillus moulds and are widespread in the food supply, particularly in low- and middle-income countries. Both in utero and infant exposure to aflatoxin B1 (AFB1 ) have been linked to poor child growth and development. The objective of this prospective cohort study was to investigate the association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes, primarily lower birth weight, in a sample of 220 mother-infant pairs in Mukono district, Uganda. Maternal aflatoxin exposure was assessed by measuring the serum concentration of AFB1 -lysine (AFB-Lys) adduct at 17.8 ± 3.5 (mean ± SD)-week gestation using high-performance liquid chromatography. Anthropometry and birth outcome characteristics were obtained within 48 hr of delivery. Associations between maternal aflatoxin exposure and birth outcomes were assessed using multivariable linear regression models adjusted for confounding factors. Median maternal AFB-Lys level was 5.83 pg/mg albumin (range: 0.71-95.60 pg/mg albumin, interquartile range: 3.53-9.62 pg/mg albumin). In adjusted linear regression models, elevations in maternal AFB-Lys levels were significantly associated with lower weight (adj-ß: 0.07; 95% CI: -0.13, -0.003; p = 0.040), lower weight-for-age z-score (adj-ß: -0.16; 95% CI: -0.30, -0.01; p = 0.037), smaller head circumference (adj-ß: -0.26; 95% CI: -0.49, -0.02; p = 0.035), and lower head circumference-for-age z-score (adj-ß: -0.23; 95% CI: -0.43, -0.03; p = 0.023) in infants at birth. Overall, our data suggest an association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes, particularly lower birth weight and smaller head circumference, but further research is warranted.

RESUMO

Environmental enteric dysfunction (EED), a subclinical disorder of the small intestine, and poor growth are associated with living in poor water, sanitation, and hygiene (WASH) conditions, but specific risk factors remain unclear. Nested within a birth cohort study, this study investigates relationships among water quality, EED, and growth in 385 children living in southwestern Uganda. Water quality was assessed using a portable water quality test when children were 6 months, and safe water was defined as lacking Escherichia coli contamination. Environmental enteric dysfunction was assessed using the lactulose:mannitol (L:M) test at 12-16 months. Anthropometry and covariate data were extracted from the cohort study, and associations were assessed using linear and logistic regression models. Less than half of the households (43.8%) had safe water, and safe versus unsafe water did not correlate with improved versus unimproved water source. In adjusted linear regression models, children from households with safe water had significantly lower log-transformed (ln) L:M ratios (ß: -0.22, 95% confidence interval (CI): -0.44, -0.00) and significantly higher length-for-age (ß: 0.29, 95% CI: 0.00, 0.58) and weight-for-age (ß: 0.20, 95% CI: 0.05, 0.34) Z-scores at 12-16 months. Furthermore, in adjusted linear regression models, ln L:M ratios at 12-16 months significantly decreased with increasing length-for-age Z-scores at birth, 6 months, and 9 months (ß: -0.05, 95% CI: -0.10, -0.004; ß: -0.06, 95% CI: -0.11, -0.006; and ß: -0.05, 95% CI: -0.09, -0.005, respectively). Overall, our data suggest that programs seeking to improve nutrition should address poor WASH conditions simultaneously, particularly related to household drinking water quality.

RESUMO

Background: Adverse birth outcomes, including preterm birth and stunting at birth, have long-term health implications. The relation between adverse birth outcomes and chronic, asymptomatic gastrointestinal inflammation (environmental enteric dysfunction-EED) is poorly understood. Objective: We aimed to examine the relation between maternal EED and adverse birth outcomes in a sample of pregnant Ugandan women and their newborn infants. Design: We conducted a prospective cohort study in Mukono, Uganda. A total of 258 pregnant women were enrolled at their first prenatal visit (∼18 weeks of gestation). EED was measured by urinary lactulose:mannitol (L:M) ratio and serum concentrations of antibodies to the bacterial components flagellin and LPS. Covariates were obtained from survey data collected at 2 time points. Associations were assessed through the use of unadjusted and adjusted simple linear regression models. Results: Complete birth outcome data were recorded for 220 infants within 48 h of delivery. Mean ± SD gestational age was 39.7 ± 2.1 wk, and 7% were born preterm. Mean ± SD length and length-for-age z score (LAZ) at birth were 48.1 ± 3.2 cm and -0.44 ± 1.07, respectively. L:M ratio was not associated with any birth outcome. In adjusted models, higher concentrations of natural log-transformed anti-flagellin immunoglobin G (IgG) and anti-LPS IgG were significantly associated with shorter length of gestation (ß: -0.89 wk; 95% CI: -1.77, -0.01 wk, and ß: -1.01 wk; 95% CI: -1.87, -0.17 wk, respectively) and with reduced length (ß: -0.80 cm; 95% CI: -1.55, -0.05 cm, and ß: -0.79 cm; 95% CI: -1.54, -0.04 cm, respectively) and LAZ at birth (ß -0.44 z score; 95% CI: -0.83, -0.05, and ß: -0.40 z score; 95% CI: -0.79, -0.01, respectively). Conclusion: Maternal anti-flagellin and anti-LPS IgG concentrations in pregnancy, but not L:M ratio, were associated with shorter gestation and reduced infant length at birth. Further research on the relation between maternal EED and birth outcomes is warranted.

RESUMO

BACKGROUND: In 2010, Uganda began developing its first multisectoral nutrition plan, the Uganda Nutrition Action Plan (UNAP), to reduce malnutrition. While the UNAP signals high-level commitment to addressing nutrition, knowledge gaps remain about how to successfully implement such a plan. OBJECTIVE: We tracked the UNAP's influence on the process of priority setting and funding for nutrition from 2013 to 2015. METHODS: This study used a longitudinal mixed methods design to track qualitative and budgetary changes related to UNAP processes nationally as well as in 2 study districts. Qualitative changes were assessed through interviews, news content, and meeting notes. Changes in allocations and expenditures were calculated based on budget documents, work plans, and validation interviews. RESULTS: Important enabling factors named by stakeholders included identity, human resources, sustainable structures, coordination, advocacy, and adaptation of the UNAP to local needs. Evidence suggests that the UNAP facilitated improvements in the last 3 factors. We found no systematic increases in planned nutrition activities, nor did we find increases in allocations or expenditures for nutrition between fiscal years 2013-2014 and 2014-2015. Expenditure data were not always available for all funding mechanisms. In the 2 study districts, there was little flexibility within financing structures to allow for additional nutrition activities. CONCLUSIONS: Results suggest the UNAP has played an important role in strengthening the enabling environment for nutrition action. The next UNAP will need to translate these improvements into a greater number of nutrition activities and higher levels of funding at the national and subnational levels.

RESUMO

BACKGROUND: The 2011 Uganda Nutrition Action Plan (UNAP) established 2016 maternal and child nutrition targets. However, there is a lack of routine district-level data collection to assess UNAP implementation. OBJECTIVE: To use Nutrition Innovation Lab (NIL) data to inform policy makers on the progress of UNAP-related indicators. METHODS: The NIL collected serial household-level survey data (n = 3600) in 6 districts, including 2 UNAP implementation districts, in 2012 and 2014. Questionnaires focused on food security, nutrition, and health, among others, and included specific indicators relevant to UNAP's targets. RESULTS: In 2012, outcomes in Kisoro and Lira districts were below national average for some UNAP key indicators, including dietary diversity and anemia prevalence, but above average for others (exclusive breastfeeding and underweight among women and children). The prevalence of child stunting was higher than national averages in Kisoro but below national averages in Lira. In 2014, anemia among women and children decreased significantly. Kisoro also saw improvements in several other UNAP target indicators including underweight, breastfeeding, and stunting. CONCLUSION: Although the study showed improvements in key UNAP indicators, there is a need to invest in appropriate methods to gauge its progress because the NIL was not designed to assess UNAP. Since the quality of implementation of complex multisectoral programs can differ widely across different contexts, it is critical that effective monitoring of progress be part of such programs. National endorsement of nutrition plans doesn't in itself result in desired outcomes, hence, the allocation of scarce resources has to be based on rigorous evidence.
