{"pk":50346,"title":"EEG Delta-Beta Coupling in 2-year-old Offspring of Pregnant Persons Receiving a Diet-and-Exercise Intervention: A Randomized Controlled Trial Follow-up","subtitle":null,"abstract":"Background: Delta-beta coupling (DBC) is a neural marker of emotion regulation (ER), with elevated DBC linked to cortical over-processing of emotional stimuli. This study investigates the effects of the Be Healthy in Pregnancy (BHIP) intervention, combining a high-protein, energy-controlled diet, nutrition counseling, and physical activity, on offspring DBC.\nMethods: Pregnant individuals received either the BHIP intervention or usual care. Twenty-four offspring at follow-up completed resting-state EEG at age two using a 128-channel system. DBC was quantified as the correlation coefficient between delta (2–4Hz) and beta (13–30Hz) power across epochs. Group differences were analyzed using Fisher's Z-tests.\nResults: BHIP offspring exhibited significantly lower DBC in frontal (p=.017), central (p=.014), and parietal (p=.009) regions compared to controls.\nConclusion: Reduced DBC reflects a neural profile linked to efficient ER, enabling context-appropriate cognitive resource allocation. These findings suggest prenatal diet and exercise potentially modulate neurodevelopment, warranting validation in larger, more diverse cohorts.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Neuroscience; Psychology; Emotion; Speech recognition; Clinical methods; cognitive neuropsychology; Electroencephalography (EEG)"}],"section":"Member Abstracts with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0d83j59r","frozenauthors":[{"first_name":"Kian","middle_name":"","last_name":"Yousefi Kousha","name_suffix":"","institution":"McMaster University","department":""},{"first_name":"John","middle_name":"","last_name":"Krzeczkowski","name_suffix":"","institution":"Brock University","department":""},{"first_name":"Neda","middle_name":"","last_name":"Moratji","name_suffix":"","institution":"McMaster University","department":""},{"first_name":"Ryan","middle_name":"","last_name":"Van Lieshout","name_suffix":"","institution":"McMaster University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T10:00:00-08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/50346/galley/38308/download/"}]}
