Home Delivery and ANC Emerge as the Most Workable Routes for BEP Supplements
Delivering balanced energy and protein supplements to pregnant and breastfeeding women is not just a nutrition problem. It is a logistics problem, a counseling problem, and in many low- and middle-income countries, a question of whether the health system can physically move food-based support to the women who need it most.
A scoping review in PLOS Global Public Health examined where those delivery systems appear to work, drawing on direct evidence for BEP supplements and indirect evidence from iron and folic acid or multiple micronutrient supplements. The review focused on low- and middle-income countries and searched both facility and community settings. Across 48 studies, 22 looked specifically at BEP delivery, while 26 examined iron and folic acid or multiple micronutrient supplements as a proxy for delivery feasibility.
The pattern that emerged was practical rather than elegant. Home delivery was the most frequently mentioned BEP platform, appearing in 11 of 22 direct-evidence studies. Community-level feeding centers, often supported by frontline community health workers and offering cooked meals or take-home rations, appeared in 8 of 22 studies. Antenatal care at health facilities appeared in 6 of 22 studies, sometimes alongside other platforms. The evidence base is not large, but it points to a core implementation reality: supplementation reaches women more reliably when delivery is embedded in the places they already live, seek care, and interact with the health system.
Why Delivery Platform Choice Matters for Maternal Nutrition
Undernutrition during pregnancy is tied to pre-eclampsia, stillbirth, and small-for-gestational-age births. Those outcomes are exactly why WHO recommends BEP supplementation in settings where underweight affects at least 20% of women of reproductive age. The biological rationale is straightforward: when maternal energy and protein intake are inadequate, fetal growth, placental development, and maternal physiologic reserve all come under strain. BEP supplements are intended to correct that deficit before it translates into poor birth outcomes.
The operational problem is less straightforward. WHO’s 2016 antenatal guidance supports BEP supplementation but gives limited direction on how to deliver it. In particular, the guideline does not settle which platform is most suitable and acknowledges that distribution through local facility-based antenatal care may not always be feasible. In many settings, the bottleneck is not whether supplementation is indicated. The bottleneck is whether the supplement can be delivered consistently, acceptably, and at enough touchpoints to matter.
One sentence in the review captures the central tension in maternal nutrition programs: the recommendation is broad, but the delivery system is local.
Home Distribution Carries the Strongest Acceptability Signal
Only four studies examined preferred BEP delivery platforms, which leaves a thin evidence base for patient preference. Even so, the direction was clear. Pregnant and breastfeeding women favored home over facility-based delivery. The review links that preference to the nutrition education and behavior change communication that accompanied home delivery.
That matters clinically because supplementation adherence is rarely driven by calories alone. Adherence depends on trust, understanding, and repeated reinforcement. A food supplement delivered without explanation can be misunderstood, shared, delayed, or discarded. A supplement delivered with counseling may be more likely to be accepted as part of pregnancy care rather than as an isolated commodity. Home delivery also reduces the burden of travel, waiting time, and competing household responsibilities, all of which can weaken uptake in women balancing pregnancy with work, caregiving, and limited mobility.
Community health workers appear repeatedly in the review because they solve a different problem: continuity. They can extend the reach of antenatal services into neighborhoods, reinforce use of the supplement, and provide the behavior change messaging that turns a distribution event into an intervention.
Community Health Workers Bridge the Gap Between Facility Care and Daily Life
The review points to community-level feeding centers anchored by frontline community health workers as another common platform for BEP supplements. These centers can offer cooked meals or take-home rations, which may be especially relevant where local food availability, household food insecurity, or cooking constraints limit the usefulness of a purely clinic-based model.
There is a clinical logic to that structure. Pregnancy nutrition interventions work best when delivery is repeated, visible, and easy to integrate into routine care. Community health workers can identify women earlier, maintain contact across pregnancy and postpartum, and support breastfeeding women as well as pregnant women. They also provide the kind of practical counseling that can improve fidelity to the intervention. In settings where the health facility is distant or overloaded, that kind of decentralized support may be the difference between nominal coverage and real coverage.
The review does not claim that one model replaces another. It shows that platform choice depends on what the system can sustain. Facility delivery may be feasible where antenatal care is strong. Home delivery may be more acceptable where transport is a barrier. Community feeding may work when local infrastructure and frontline personnel are in place.
Facility-Based ANC Still Has a Role, Especially When Reinforced
Antenatal care at health facilities appeared in 6 of the 22 BEP studies and was also relevant in the indirect evidence from iron and folic acid or multiple micronutrient supplementation. The broader supplement literature suggests that strengthening facility delivery with behavior change communication and home visits may improve compliance. That indirect evidence does not prove the same effect for BEP, but it does support a plausible service model: facility contact establishes the intervention, while community follow-up sustains it.
For program planners, this is the most actionable shape of the evidence. BEP supplementation does not have to be delivered through a single rigid pathway. It can be layered. Antenatal care can identify eligible women and initiate supplementation. Community health workers can reinforce use, solve access barriers, and extend follow-up beyond the clinic. Home delivery can increase acceptability where women are unlikely to return frequently to a facility.
A market-based approach remained poorly studied across all of the interventions reviewed. Commercial or market distribution may someday matter more, but the current evidence base is too thin to treat it as a reliable scaling strategy.
What the Review Can and Cannot Support
This is a scoping review, so the purpose is mapping rather than proving superiority. It does not establish which platform produces the best maternal or infant outcomes, and it does not measure the full costs, supply chain demands, or equity effects of each delivery model. It also blends direct BEP evidence with indirect evidence from iron and folic acid or multiple micronutrient supplementation, which broadens the practical lens but introduces a clear difference in intervention type.
Even with those limits, the evidence points in one direction: BEP supplements are most likely to reach pregnant and breastfeeding women when delivery is close to home, supported by frontline community health workers, and anchored where women already enter care. Facility-based antenatal care remains relevant, but on its own it may not be enough in settings with weak access or low continuity.
Scale-up decisions will still depend on local health-system capacity, staffing, and the feasibility of pairing supplements with counseling. The review leaves one practical question open: which hybrid delivery model can be sustained at scale without losing adherence, acceptability, or reach across the women WHO guidelines are meant to protect.
