Verbal and figural memory tasks at baseline and after one year were completed using a standardized, computerized cognitive test battery. Use of wireless devices was inquired by questionnaire and operator recorded mobile phone use data was obtained for a subgroup of 234 adolescents. RF-EMF dose measures considering various factors affecting RF-EMF exposure were computed for the brain and the whole body. Data were analysed using a longitudinal approach, to investigate whether cumulative exposure over one year was related to changes in memory performance. All analyses were adjusted for relevant confounders.\n\nResults: The kappa coefficients between cumulative mobile phone call duration and RF-EMF brain and whole body dose were 0.62 and 0.67, respectively for the whole sample and 0.48 and 0.28, respectively for the sample with operator data. In linear exposure-response models an interquartile increase in cumulative operator recorded mobile phone call duration was associated with a decrease in figural memory performance score by -0.15 (95% CI: -0.33, 0.03) units. For cumulative RF-EMF brain and whole body dose corresponding decreases in figural memory scores were -0.26 (95% CI: -0.42, -0.10) and -0.40 (95% CI: -0.79, -0.01), respectively. No exposure-response associations were observed for sending text messages and duration of gaming, which produces tiny RF-EMF emissions.\n\nConclusions: A change in memory performance over one year was negatively associated with cumulative duration of wireless phone use and more strongly with RF-EMF dose. This may indicate that RF-EMF exposure affects memory performance.\"\n","attachments":[],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-6402","tags":["sleep-cognition","research-evidence"],"source_hash":"592c38e33c25b08ab971ed5da529e95ce716eeb6415b16a86c812627c0babf5c","slug":"sleep-cognition-comment-6402","classification":{"id":"HHS-OASH-2026-0397-6402","body_sha256":"3a8446fc8dea8f201057a43ce13b22c7da77e9314cd6e69a9d0f0f1c8dab38cb","status":"ai_reviewed","primary_topic":"research","topics":[{"id":"research","evidence":" to radiofrequency electromagnetic fields: A prospective cohort study in adolescents\" \n\n\"Abstract\nBackground: The aim of this study is"},{"id":"children","evidence":"gnetic fields: A prospective cohort study in adolescents\" \n\n\"Abstract\nBackground: The aim of this study is to investigate"},{"id":"neurological","evidence":"ohort study with 439 adolescents.
