BMJ Open protocol maps climate change strategies for women and children
Climate change has moved from an environmental abstraction to a direct clinical concern for women and children, two populations that often carry the earliest and most durable health consequences of heat, displacement, food insecurity, and disrupted care. A scoping review protocol published in BMJ Open sets out to chart the range of strategies used to address climate-related harms in these groups, with attention to health services, community action, and policy responses. The project is designed to map what exists, where the evidence sits, and how researchers and health systems are responding to the growing burden.
The review is structured as a protocol rather than a results paper, so its value lies in the architecture of the search and the clarity of the clinical question. The investigators plan to follow Joanna Briggs Institute methodological guidance and PRISMA-ScR standards, a combination that is intended to promote transparency, reproducibility, and consistency in study selection. In practical terms, that means the final review should not only describe the evidence base, but also make clear how that evidence was found and why particular sources were included or excluded.
Climate stress does not affect women and children in a uniform way. Pregnancy can amplify vulnerability to heat and environmental instability, while children face risks tied to immature thermoregulation, airway development, nutrition, and dependence on caregivers and infrastructure. When extreme weather disrupts antenatal visits, vaccinations, school attendance, water safety, or nutrition programs, the clinical consequences often appear quickly and then persist. A review focused on strategies, rather than only harms, is therefore clinically relevant because it can identify interventions that preserve care delivery even when the surrounding environment becomes less predictable.
A broad search strategy across clinical, community and policy settings
The protocol calls for a broad search across major bibliographic databases and grey literature sources. That choice is important because climate adaptation work often appears outside the traditional clinical journal pathway. Public health agencies, nongovernmental organizations, community programs, and policy reports may contain interventions that are highly relevant to women’s and children’s health but are easy to miss if the search is too narrow.
Study selection will be handled independently by two reviewers using predefined eligibility criteria. Independent screening reduces the chance that one reviewer’s assumptions will shape the evidence map. For a scoping review, where the goal is breadth rather than effect-size estimation, that design choice matters because it determines whether the final synthesis reflects a genuinely wide capture of the literature or a truncated one.
Only studies published in English, Portuguese, or Spanish will be included. This language restriction is explicit and clinically important. Climate-related health strategies are often tested in regions where other languages dominate, and some relevant work may never appear in the final map if it falls outside those three languages. The protocol also states that no formal critical appraisal of methodological quality will be performed, which fits the logic of a scoping review but leaves the eventual synthesis focused on availability and range of evidence rather than confidence in individual study quality.
There is a practical reason protocol-driven reviews matter in this area. Climate adaptation research can be scattered across maternal health, pediatrics, emergency preparedness, environmental medicine, urban planning, and health systems research. Without a structured map, a hospital administrator trying to protect neonatal services during heat waves may never see the same evidence as a policymaker designing community cooling interventions, even when both are responding to the same physical threat.
Why women and children require a separate evidence map
A climate strategy that works in the general population may fail when applied to pregnancy, infancy, or childhood. Care pathways for these groups are more time-sensitive, more dependent on continuity, and more vulnerable to social disruption. Maternal health services rely on scheduled contact points that can be derailed by extreme weather, transport barriers, or infrastructure damage. Pediatric systems depend on immunization, growth monitoring, nutrition support, and family engagement, all of which can unravel when a community is under environmental strain.
The protocol’s emphasis on health services, communities, and policy contexts reflects that reality. Health service interventions may include delivery redesign, outreach, continuity planning, or emergency readiness. Community-level strategies may involve local support networks, education, or environmental protections. Policy responses can shape the conditions in which families access care, shelter, food, clean water, and public health messaging. Each layer acts on a different part of the causal chain, from exposure to care access to downstream illness.
One sentence captures the bedside relevance plainly: climate adaptation is no longer an abstract policy discussion when an obstetric clinic loses power or a pediatric ward is overwhelmed by heat-related illness.
The protocol does not test a drug, a device, or a single clinical pathway. Its aim is different and broader: to assemble the existing strategies and determine where the field has already generated usable answers. For clinicians, that distinction matters because the final review may identify gaps as well as examples of workable adaptation, especially in settings with limited resources or high climate exposure.
What the finished review may clarify for practice and policy
Because this is a scoping protocol, the most important output will come later, after the evidence has been collected and charted. Even so, the design signals several likely payoffs. It should help define which types of climate strategies have been studied most often, which populations are represented, and whether the evidence is concentrated in high-income settings or dispersed across different health systems. It may also reveal whether interventions are aimed primarily at preventing harm, improving resilience, or restoring services after disruption.
For women’s and children’s health, the stakes are concrete. Heat exposure, food insecurity, displaced care, and contaminated water do not remain theoretical hazards for long. They can present as preterm birth risk, dehydration, missed vaccinations, interrupted antenatal monitoring, respiratory illness, or worsening nutritional status. A well-constructed evidence map can help identify which responses are grounded in actual field experience and which areas remain thinly studied.
The protocol’s strongest feature is its breadth. The chief limitation is built into its eligibility rules: evidence published outside English, Portuguese, or Spanish may be missed, and no formal quality appraisal will be applied to the included sources. Those constraints do not weaken the review’s purpose, but they do define its scope. The final paper will be most useful as a map of the terrain, not a ranking of the best available intervention. That is the right starting point for a field where the clinical consequences of climate change are already arriving faster than many care systems can adapt.
