PROCOMIDA, a Food-Assisted Maternal and Child Health and Nutrition Program, Contributes to Postpartum Weight Retention in Guatemala: A Cluster-Randomized Controlled Intervention Trial.

ABSTRACT: BACKGROUND:Food-assisted maternal and child health and nutrition (FA-MCHN) programs are widely used to reduce household food insecurity and maternal and child undernutrition in low- and middle-income countries. These programs, however, may unintentionally lead to excessive energy intake and unhealthy weight gain, especially in food-secure populations. OBJECTIVE:We evaluated the impact of an FA-MCHN program implemented in Guatemala on maternal weight from pregnancy to 24 mo postpartum. The program was earlier shown to reduce stunting. METHODS:We used a longitudinal, cluster-randomized controlled trial with arms varying in family ration size [full (FFR), reduced (RFR), none (NFR)] and individual maternal ration type [corn-soy blend (CSB), lipid-based nutrient supplement (LNS), micronutrient powder (MNP)]: A: FFR + CSB; B: RFR + CSB; C: NFR + CSB; D: FFR + LNS; E: FFR + MNP; F: control. Weight was measured during pregnancy and at 1, 4, 6, 9, 12, 18, and 24 mo postpartum. We used linear mixed models controlling for pregnancy weight with random cluster and mother effects. Data on 3535 women were analyzed. RESULTS:Significant (P < 0.05) or marginally significant (P < 0.10) effects of 0.50-0.65 kg were found at all time points (except 9 mo) in arm A. Similar-sized effects were found in arms B (1, 4, 6, and 12 mo) and C (1 and 12 mo). Marginally significant effects (0.51-0.66 kg) were found in arm D (1, 6, 9, and 12 mo); in arm E, marginally significant effects (0.48-0.75 kg) were found from 6 to 24 mo. CONCLUSIONS:The effect on maternal postpartum weight is of concern because of the high existing prevalence of overweight. Programs need to include "double-duty" objectives and actions, to ensure that addressing child undernutrition does not exacerbate the problem of unhealthy weight gain. This trial was registered at clinicaltrials.gov as NCT01072279.

Project description:BackgroundFood-assisted maternal and child health and nutrition (FA-MCHN) programs may foster child growth during the first 1000 d (pregnancy and the first 2 y of a child's life), but evidence is scant.ObjectiveWe evaluated the impact of an FA-MCHN program, PROCOMIDA, on linear growth (stunting [length-for-age z score (LAZ) < -2] and length-for-age difference [LAD]) among children aged 1-24 mo. PROCOMIDA was implemented in Guatemala by Mercy Corps and was available to beneficiaries throughout the first 1000 d.MethodsWe used a longitudinal, cluster-randomized controlled trial with groups varying in family ration sizes [full (FFR), reduced (RFR), and none (NFR)] and individual ration types provided to mothers (pregnancy to 6 mo postpartum) and children (6-24 mo of age) [corn-soy blend (CSB), lipid-based nutrient supplement (LNS), micronutrient powder (MNP)]: 1) FFR + CSB (n = 576); 2) RFR + CSB (n = 575); 3) NFR + CSB (n = 542); 4) FFR + LNS (n = 550); 5) FFR + MNP (n = 587); 6) control (n = 574). Program impacts compared with control, and differential impacts between groups varying family ration size or individual ration type, were assessed through the use of linear mixed-effects models and post hoc simple effect tests (significant if P < 0.05).ResultsPROCOMIDA significantly reduced stunting at age 1 mo in FFR + CSB, RFR + CSB, and FFR + MNP groups compared with control [5.05, 4.06, and 3.82 percentage points (pp), respectively]. Stunting impact increased by age 24 mo in FFR + CSB and FFR + MNP relative to control (impact = 11.1 and 6.5 pp at age 24 mo, respectively). For CSB recipients, the FFR compared with RFR or NFR significantly reduced stunting (6.47-9.68 pp). CSB reduced stunting significantly more than LNS at age 24 mo (8.12 pp).ConclusionsFA-MCHN programs can reduce stunting during the first 1000 d, even in relatively energy/food-secure populations. Large family rations with individual rations of CSB or MNP were most effective. The widening of impact as children age highlights the importance of intervening throughout the full first 1000 d. This trial was registered at clinicaltrials.gov as NCT01072279.

Project description:BACKGROUND:North Carolina Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) resources improve child body mass index (BMI) when the resources are introduced by nurses to child care providers, and offered with workshops and incentives. In San Francisco, public health and child care agencies partnered to adapt NAP SACC resources into an annual "Healthy Apple" quality improvement program (HAP). METHODS:This cluster randomized controlled trial pilot-tested integration of the HAP with bi-annual public health screenings by nurses. All child care centers that participated in Child Care Health Program (CCHP) screenings in San Francisco in 2011-2012 were offered routine services plus HAP in 2012-2013 (CCHP?+?HAP, n?=?19) or routine services with delayed HAP in 2014-2015 (CCHP?+?HAP Delayed, n?=?24). Intention-to-treat analyses (robust SE or mixed models) used 4 years of screening data from 12 to 17 CCHP?+?HAP and 17 to 20 CCHP?+?HAP Delayed centers, regarding 791 to 945 children ages 2 to 5y, annually. Year-specific, child level models tested if children in CCHP?+?HAP centers had greater relative odds of exposure to 3 index best practices and smaller Autumn-to-Spring changes in BMI percentile and z-score than children in CCHP?+?HAP Delayed centers, controlling for age, sex, and Autumn status. Multi-year, child care center level models tested if HAP support modified year-to-year changes (2013-2014 and 2014-2015 vs 2011-2012) in child care center annual mean Autumn-to-Spring BMI changes. RESULTS:In 2011-2012, the CCHP?+?HAP and CCHP?+?HAP Delayed centers had similar index practices (<15% of children were exposed to a physical activity curriculum, staff joining in active play, and drinking water pitchers) and annual BMI changes. In 2013-2014: 60% of children in CCHP?+?HAP centers were exposed to the 3 index practices vs 19% in CCHP?+?HAP Delayed centers; Mean (SE) child BMI percentile (-2.6 (0.9), p?=?0.003) and z-score (-0.08 (0.03), p?=?0.007) decreased more in CCHP?+?HAP vs CCHP?+?HAP Delayed centers. In 2014-2015, after all centers were offered HAP, the index practices and BMI changes were improved for all centers vs 2011-2012. CONCLUSIONS:Integration of the HAP with existing public health nursing services was associated with significantly more children exposed to best practices and improvement in child BMI change. The results warrant continued integration of HAP into local public health infrastructure. TRIAL REGISTRATION:ISRCTN18857356 (24/04/2015) Retrospectively registered.

Project description:BackgroundLittle is known about the impact of food-assisted maternal and child health programs (FA-MCHN) on child wasting.ObjectivesWe assessed the impact of Tubaramure, a FA-MCHN program in Burundi, on child (0 to 24 months) wasting and the differential impacts by socio-economic characteristics and age. The program targeted women and their children during the first 1000 days and included 1) food rations, 2) strengthening and promotion of use of health services, and 3) behavior change communication (BCC).MethodsWe conducted a 4-arm, cluster-randomized, controlled trial (2010-2012). Clusters were defined as "collines" (communities). Impact was estimated using repeated cross-sectional data (n = ∼2620 children in each round). Treatment arms received household and individual (mother or child in the first 1000 days) food rations (corn-soy blend and micronutrient-fortified vegetable oil) from pregnancy to 24 months (T24 arm), from pregnancy to 18 months (T18), or from birth to 24 months (TNFP). All beneficiaries received the same BCC for the first 1000 days. The control arm received no rations or BCC.ResultsWasting (weight-for-length Z-score <2 SD) increased from baseline to follow-up in the control group (from 6.5% to 8%), but Tubaramure had a significant (P < 0.05) protective effect on wasting [treatment arms combined, -3.3 percentage points (pp); T18, -4.5 pp] and on the weight-for-length z-score (treatment arms combined, +0.15; T24, +0.20; T18, +0.17). The effects were limited to children whose mother and household head had no education, and who lived in the poorest households. The largest effect was found in children 6 to 12 months of age: the group with the highest wasting prevalence.ConclusionsFA-MCHN programs in highly food-insecure regions can protect the most disadvantaged children from wasting. These findings are particularly relevant in the context of the economic crisis due to the coronavirus disease 2019 pandemic, which is expected to dramatically increase child wasting.

Project description:BackgroundStunting rates remain unacceptably high in many regions, including sub-Saharan Africa. Agricultural programs have led to increased yields and household incomes but showed limited success in improving nutritional status.ObjectivesWe assessed whether linear growth could be improved through a potentially scalable, integrated program adding nutrition-specific and nutrition-sensitive components to an existing agricultural program.MethodsIn this cluster-randomized controlled trial in rural Western Kenya, we randomized children aged 6-35 months from farming families to an agricultural intervention without (control group) or with a bundle of interventions (intervention group), including distribution of micronutrient powders (MNP), poultry to increase egg consumption, seeds of greens and onions, and soap and chlorine solution, as well as provision of monthly behavior change trainings. The primary outcome was the change in height-for-age z-score (HAZ) over 2 years of follow-up. We assessed safety through active morbidity and passive adverse event monitoring. We conducted an intention-to-treat analysis, followed by per-protocol and prespecified subgroup analyses.ResultsFrom March to April 2018, we enrolled 1927 children from 126 clusters (control, 942 children in 63 clusters; intervention, 985 children in 63 clusters). Data on HAZ were available for 1672 (86.6%) children after 2 years. Adherence was >80% for use of MNP, chlorine, and greens and receipt of soap, and ∼40% for egg and red onion consumption. The intention-to-treat analysis indicated a greater change in HAZ over 2 years in the intervention group (adjusted effect size, 0.11; 95% CI: 0.02-0.19). We found a slightly stronger effect in the per-protocol analysis (adjusted effect size, 0.15; 95% CI: 0.06-0.24). Dietary diversity and consumption of iron-rich foods were improved in the intervention group, and reported instances of fever, lower respiratory tract infections, and diarrheal episodes were lower in the intervention group.ConclusionsThis study found a modest improvement in linear growth, indicating the need for multiple, integrated interventions to achieve benefits. The trial was registered with clinicaltrials.gov as NCT03448484.

Project description:IntroductionEver since the 1960s, Guatemala has been a principle site for global academic research on child growth and nutrition. Nevertheless, Guatemala still has one of the highest rates of child stunting in the world. Since 2012, Guatemala has had a comprehensive national policy on stunting, calling for a renewed investment in innovative, multilevel nutrition interventions and implementation science. Our objective was to perform a systematic search and scoping review of the literature on stunting in Guatemala to identify gaps in research and opportunities for responding to this unique policy opportunity.MethodsWe conducted a systematic search and scoping review on stunting in Guatemala, searching the PubMed, Web of Science and PsycINFO databases. Eligible articles were of any design or format, published in English and Spanish from 2000 to 2018. Articles were thematically grouped by those published before (2000-2011) and after (2012-2018) the new national policy initiatives.ResultsWe identified a total of 1934 articles through database searches. After full-text review, 104 were included in the synthesis. The volume of published articles on stunting increased from a mean of 3.2 to 9.4 articles/year before and after 2012. There was a shift toward articles generating new data on priority populations, including rural indigenous Maya populations (34% vs 61%, χ2 test, p=0.01). However, the proportion of studies conducting implementation evaluations or testing new interventions was low and did not change significantly (34% vs 18%, χ2 test, p=0.07). Among 17 identified intervention studies, only 4 tested multilevel interventions, and there were no published interventions incorporating nutrition-sensitive interventions.ConclusionsA systematic search and scoping review of the literature on child stunting in Guatemala identified critical opportunities for new research in multilevel interventions, nutrition-sensitive interventions and implementation science.

Project description:BackgroundFood-assisted maternal and child health and nutrition programs are a widely used approach to address undernutrition. Little is known about the effects of these programs' combined household and individual food rations on household and individual food consumption. Tubaramure in Burundi targeted women and children during the first 1000 d of life, and included: 1) food rations (corn-soy blend and micronutrient-fortified vegetable oil); 2) health services strengthening and promotion of their use; and 3) behavior change communication on nutrition, hygiene, and health practices.ObjectivesThe objectives were: 1) to assess Tubaramure's impact on household food consumption and food security, maternal dietary diversity, and infant and young child feeding practices; 2) to explore the role of the food rations; and 3) assess 6-8 mo impacts around 8 mo after the end of the program.MethodsWe used a 4-arm cluster-randomized controlled repeated cross-sectional design (11,906 observations). The treatment arms received the same food ration but differed in the ration timing and duration: 1) the first 1000 d; 2) from pregnancy through 17.9 mo of age; or 3) from birth through 23.9 mo of age.ResultsTubaramure significantly (P < 0.05) improved the percentage of food secure households [from 4.5 to 7.3 percentage points (pp)], and increased household energy consumption (from 17% to 20%) and micronutrient consumption. The program had a positive effect on maternal dietary diversity (+0.4 food groups, P < 0.05) and increased the proportion of children aged 6-23.9 mo consuming ≥4 food groups (from 8.0 to 9.6 pp, P < 0.05). The effects on many outcomes were attributable to the food rations. Postprogram effects (P < 0.05) were found on household food security, maternal dietary diversity, and younger sibling's complementary feeding practices.ConclusionsPrograms such as Tubaramure have the potential to improve food security and household and individual energy and micronutrient consumption in severely resource-constrained populations, as seen in rural Burundi. This trial was registered at clinicaltrials.gov as NCT01072279.
