IJERPH Submission Guide: MDPI Process and Indexing (2026)

IJERPH is not a stronger or weaker version of a subscription public-health journal. It is a different model. MDPI built it around speed and soundness-based review: the editorial question is whether the work is methodologically sound, in scope, and tied to health promotion, not whether it ranks among the most selective findings of the year. Two things follow.

First, the scope filter is real and specific. IJERPH explicitly expects every study to show how the results have a direct impact on health promotion, and it asks that regional studies be framed within a global context. This is not boilerplate. A clean environmental-chemistry or basic-biology paper with no population-health payoff is exactly the kind of manuscript the journal was criticized for publishing before the 2023 Web of Science delisting, and the editorial pre-check now screens for it harder than authors expect.

Second, the pre-check is fast and partly template-driven, so completeness and claim discipline are rewarded and incompleteness is punished early. A technically competent study that overstates what a cross-sectional design can show, or that ships with a stub ethics statement, can be returned before a reviewer sees it, while a sound, in-scope, well-declared study moves quickly.

The honest caveat: what slows or sinks an IJERPH submission

After the delisting, MDPI cut IJERPH's monthly output sharply and reset the editorial bar around content relevance. For an author, that means the journal is more selective on scope than its older reputation suggests, and the scope question is now the first thing to get right.

Two things slow real submissions: a reviewer search that stalls when the topic is narrow, and a pre-check return for scope or claim-discipline problems that a quick self-audit would have caught. The journal is fast when your package is clean and in scope; it is not fast when the editor has to send it back.

The core fit for most submissions is the original research article. It works best when the public-health question is central, the methods are reproducible from the text, the claims match the design, and the declarations and reporting package are complete on first upload.

Ask these questions before you submit:

• does the study name a concrete impact on health promotion or disease prevention, or is the health link only implied?
• do the claims match the design, or does a cross-sectional or survey study slide into causal language in the abstract and discussion?
• is the sample described honestly, or is a small convenience sample generalized to a whole population?
• are the ethics, consent, and data statements complete and specific, or are they still stub text?

If the answers are uncertain, the scope-and-claims problem is usually more important than the data problem.

The pre-check editor is answering a short list of questions fast.

On scope, the editor asks whether the manuscript belongs in a public-health journal and whether it shows a direct health-promotion impact. If the health link is thin, implied, or bolted on, the paper is returned or redirected. The editor has read thousands of openings that bury the public-health payoff under method detail, and a paper that does this is already losing before the data is read.

On claim discipline, the editor checks whether the conclusions are sized to the design. Cross-sectional and survey work that uses causal verbs, or a small sample presented as representative, reads as an integrity risk, not an ambitious finding. On integrity, the editor checks whether ethics approvals, consent, image-integrity expectations, and data availability are all in order; MDPI runs integrity and plagiarism checks at pre-check, and gaps trigger fast returns.

On completeness, the editor looks for the declarations block. A manuscript missing Author Contributions, Funding, Data Availability, or Conflicts of Interest reads as not ready, even when the science is fine.

Manuscript structure: IJERPH expects a defined section set: Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion, Conclusions, plus the declarations block. The journal sets no fixed maximum length, but it expects the text to be concise; a sprawling manuscript reads as unfocused. The abstract is the first thing the pre-check editor reads, so the public-health question and the health-promotion payoff both need to be visible there, not held back for the discussion.

Reporting and methods readiness: Provide full experimental and analytical detail so results can be reproduced, and follow the design-appropriate guideline: STROBE for observational studies (cohort, case-control, cross-sectional), PRISMA for systematic reviews and meta-analyses with a registered protocol, CONSORT for randomized trials, ARRIVE for animal work. A study whose methods do not map cleanly onto its reporting checklist is the most common reviewer-stage friction point in public-health submissions.

Claim calibration: Walk every conclusion back to the design. For a cross-sectional study, the strongest honest claim is association under stated assumptions, and the limitations paragraph should name confounding, temporality, and selection explicitly. This is editorial work you do before upload, not a revision you wait for a reviewer to demand.

Declarations and ethics: Draft the Institutional Review Board statement (with an approval number), Informed Consent statement, Author Contributions (by initials), Funding, Data Availability, and Conflicts of Interest sections before you upload. At MDPI these are pre-check gates, not post-acceptance paperwork.

Figures, supplementary, and assets: A graphical abstract is optional but common; if supplied, use a high-resolution PNG, JPEG, or TIFF. Supplementary materials carry the detail that would slow the main narrative, including the completed reporting checklist. ORCID is expected for the submitting author, and the system asks for suggested reviewers.

In our pre-submission review work with IJERPH manuscripts, four failure patterns generate the most consistent pre-check returns and reviewer friction, and each is testable against your own draft before you upload. The four named patterns are scope drift, overstated causality, convenience-sample overreach, and an incomplete declarations block.

Across our IJERPH pre-submission reviews, the pattern that surprises authors most is that the pre-check is not a quality filter in the Nature sense; it is a scope-and-claim-discipline filter sharpened by the 2023 Web of Science content-relevance episode. The manuscripts that get returned fastest are rarely bad science. They are competent studies whose health-promotion link, claim sizing, sample framing, or declarations block is not ready for a fast, template-driven screen. Manuscripts coming through pre-submission review for IJERPH split cleanly along these four lines.

Scope drift: a study with no direct health-promotion payoff

The single most common pattern we see is a manuscript whose public-health relevance is downstream rather than central. The study is really environmental chemistry, basic toxicology, geospatial analysis, or a methods paper, and a sentence about "potential implications for public health" is added so the work can target IJERPH.

Because IJERPH expects a direct health-promotion or disease-prevention payoff, the pre-check editor returns or redirects these fast. The testable version: read your own abstract and ask whether a public-health editor could name the health-promotion outcome from the first paragraph alone. If the health link only appears as a closing "future work" sentence, the scope is too thin, and the fix is to rebuild the introduction and abstract around the population-health question rather than around the method or the exposure measurement.

Cross-sectional and survey designs with overstated causal claims

The second pattern is a claim-to-design mismatch. An IJERPH manuscript reports a cross-sectional survey, an ecological correlation, or a single-timepoint association, and then the abstract and discussion use causal language: the exposure "reduces," "improves," or "leads to" the outcome.

Reviewers in public health are trained to flag this, and the pre-check editor often catches it first. The testable version: search your own abstract, results, and conclusions for causal verbs, and for every one, confirm the design actually supports causation. If it is cross-sectional, the honest claim is association, and the limitations paragraph must name confounding and temporality. This is the highest-leverage single edit for most IJERPH submissions, because it converts an integrity concern into a defensible, publishable finding.

Small convenience samples framed as generalizable

The third pattern is a sample-framing problem. The study recruits a small or non-probability convenience sample, often from a single clinic, campus, or region, and then the manuscript generalizes the result to a national or global population without a representativeness argument or a sample-size justification.

IJERPH asks that regional studies be framed within a global context, and that is not an invitation to overclaim; it is a request for honest positioning. The testable version: state your sampling frame and sample size explicitly in the methods, add a power or sample-size rationale, and in the discussion describe who the findings apply to and who they do not. A small study that is honest about its reach is publishable at IJERPH; a small study dressed up as a population estimate is not.

Missing ethics, reporting-standard, and data-availability elements

The fourth pattern is an incomplete declarations and reporting block. We repeatedly see human-subjects studies with no IRB approval number, observational studies with no STROBE checklist, systematic reviews with no PRISMA diagram and no registered protocol, and a Data Availability Statement that reads only "available on request." MDPI treats these as pre-check gates, so a single missing element can return the manuscript before review.

The testable version: for every claim that touches participants, exposure data, or animals, confirm a corresponding ethics statement with a real identifier; attach the design-matched reporting checklist (STROBE, PRISMA, CONSORT); and make the Data Availability Statement name where the data actually lives.

Each of these is something you can check against your own draft before you commit the submission. This guide tells you what IJERPH editors look for; the review tells you whether YOUR paper passes the pre-check before you upload.

Across the public-health and environmental-health manuscripts Manusights has reviewed, the scope-drift and overstated-causality patterns above are the two most common reasons authors lose a fast pre-check, and both are fixable before upload. Paid Manusights reviews include a 60-day money-back guarantee, and we do not train models on submitted manuscripts. Run an IJERPH submission package check to see whether your scope framing, claim discipline, and declarations block will clear the MDPI pre-check.

IJERPH reports a median first decision near 30 days, and author-reported SciRev data puts the first review round at roughly 5.4 weeks. Treat these as planning ranges, not promises: manuscripts that clear pre-check and enter reviewer search in a narrow subfield can run longer.

• Day 0: Submission via SuSy. The portal accepts the package and routes it to the section or topic editor for pre-check.

• Days 1 to 3: Editorial pre-check. The editor screens health-promotion scope, claim discipline, ethics completeness, integrity and plagiarism checks, and basic soundness.

The fastest returns happen here, before any reviewer is invited.

• Days 3 to 10: Reviewer invitation. Manuscripts that pass pre-check enter single-blind reviewer search, typically targeting two or more reviewers in the relevant public-health or environmental-health subfield.

• Days 10 to 30: Peer review and first decision. Reviewer reports return and the editor issues the first decision, with a median near 30 days from submission.

Major revision is the most common outcome for papers that clear pre-check.

• Days 30 to 55: Revision and acceptance. Revisions are usually requested on a short clock; resubmission and a second review cycle commonly land acceptance inside a few weeks for in-scope, complete packages.

• Days 45 to 50: Production and publication. MDPI production is fast, so the slow part of the calendar is reviewer search and revision, not typesetting.
