Although rapid diagnostic tests (RDTs) enable timely screening, false-negative results and delays in confirmatory microscopy can hinder early treatment in resource-limited settings. This study developed and evaluated an automated machine learning (AutoML)-based framework for early malaria risk prediction using demographic, household, and socioeconomic data from the nationally representative Nigeria Malaria Indicator Survey (MIS) 2021. Initially, 43 candidate variables were selected and subsequently reduced to 13 statistically significant predictors through preprocessing and statistical dependency testing. Five machine learning models, namely Logistic Regression (LR), Decision Tree (DT), Support Vector Classifier (SVC), Extreme Gradient Boosting (XGBoost), and H2O AutoML, were developed and evaluated using stratified train\u2013test splitting and 10-fold cross-validation. To reduce the influence of regional information, Agglomerative Hierarchical Clustering (AHC) was performed using the eight most important predictors after excluding regional identifiers, yielding two optimal population subgroups (Silhouette Score\u2009=\u20090.3939). For the overall dataset, H2O AutoML Generalized Linear Model (GLM) achieved the highest F\n                    <jats:sub>2<\/jats:sub>\n                    -score (79.38%) with a recall of 83.08%, whereas XGBoost achieved the highest test accuracy (75.54%). Cluster-specific analyses demonstrated that H2O GLM provided the best recall-oriented performance in Cluster 1 (F\n                    <jats:sub>2<\/jats:sub>\n                    -score\u2009=\u200983.31%), while XGBoost performed best in Cluster 2 (F\n                    <jats:sub>2<\/jats:sub>\n                    -score\u2009=\u200983.25%). These findings demonstrate that H2O AutoML provides a robust and automated framework for malaria risk prediction, while cluster-specific modeling further improves predictive performance by accounting for population heterogeneity. The proposed framework has the potential to support early malaria risk assessment and complement conventional diagnostic strategies in resource-limited public health settings.\n                  <\/jats:p>","DOI":"10.1371\/journal.pdig.0001736","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T17:28:25Z","timestamp":1790184505000},"page":"e0001736","update-policy":"https:\/\/doi.org\/10.1371\/journal.pdig.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Early malaria risk screening in Nigerian minors using AutoML and cluster-based analysis of non-clinical survey data"],"prefix":"10.1371","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1999-3041","authenticated-orcid":true,"given":"Ashiqur Rahman","family":"Khan","sequence":"first","affiliation":[{"name":"Bangladesh University of Engineering and Technology (BUET)","place":["Dhaka, Bangladesh"],"department":["Department of Industrial and Production Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5891-3107","authenticated-orcid":true,"given":"Nafisa","family":"Mahbub","sequence":"additional","affiliation":[{"name":"Bangladesh University of Engineering and Technology (BUET)","place":["Dhaka, Bangladesh"],"department":["Department of Industrial and Production Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ridwan Al","family":"Aziz","sequence":"additional","affiliation":[{"name":"Bangladesh University of Engineering and Technology (BUET)","place":["Dhaka, Bangladesh"],"department":["Department of Industrial and Production Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3868-1861","authenticated-orcid":true,"given":"Mahamudul Hassan","family":"Siddique","sequence":"additional","affiliation":[{"name":"Bangladesh University of Engineering and Technology (BUET)","place":["Dhaka, Bangladesh"],"department":["Department of Industrial and Production Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahidul Islam","family":"Sayeem","sequence":"additional","affiliation":[{"name":"Bangladesh University of Engineering and Technology (BUET)","place":["Dhaka, Bangladesh"],"department":["Department of Industrial and Production Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"pdig.0001736.ref001","unstructured":"World Health Organization.
