Health professions students are exposed to severe academic stress and multiple lifestyle\u2010related factors that may influence autonomic regulation. This study aimed to evaluate HRV profiles in health professions students and examine associations with academic stress and lifestyle factors. A cross\u2010sectional study was conducted among 237 students (81.4% females). HRV was assessed under standardized resting conditions using time\u2010domain, frequency\u2010domain, and Poincar\u00e9 plot\u2010derived geometrical indices. Autonomic status was classified as normal autonomic function (NAF), low HRV (LHRV), parasympathetic dominance (PD), or sympathetic dominance (SD). Associations with body mass index, smoking, physical activity, sleep quality, and perceived stress were analyzed using chi\u2010square and correlation tests. Normal autonomic function was observed in 65.0% of students, while 35.0% exhibited autonomic imbalance (16.9% PD, 16.9% SD, and 1.3% LHRV). No significant associations were found with lifestyle factors (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05).

In conclusion, most students demonstrated preserved autonomic function, although approximately one\u2010third showed autonomic imbalance. Academic stress was significantly associated with autonomic function, particularly among female students.\n                  <\/jats:p>","DOI":"10.14814\/phy2.71012","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T04:54:40Z","timestamp":1783400080000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Heart rate variability and autonomic function in health professions students: Associations with academic stress and lifestyle factors"],"prefix":"10.14814","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9512-2098","authenticated-orcid":false,"given":"Azza","family":"Alawad","sequence":"first","affiliation":[{"name":"Faculty of Medicine Al\u2010Neelain University  Khartoum Sudan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4827-8338","authenticated-orcid":false,"given":"Tarig","family":"Merghani","sequence":"additional","affiliation":[{"name":"RAK College of Medical Sciences RAK Medical and Health Sciences University  Ras Al\u2010Khaimah UAE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3167-8241","authenticated-orcid":false,"given":"Nishaat","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"RAK College of Medical Sciences RAK Medical and Health Sciences University  Ras Al\u2010Khaimah UAE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5168-1969","authenticated-orcid":false,"given":"Hibat Alla","family":"Hisham","sequence":"additional","affiliation":[{"name":"RAK College of Medical Sciences RAK Medical and Health Sciences University  Ras Al\u2010Khaimah UAE"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,6]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.52338\/jocd.2025.4936"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0165-1781(89)90047-4"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/abm\/kaaa039"},{"issue":"5","key":"e_1_2_12_5_1","first-page":"1043","article-title":"Heart rate variability: Standards of measurement, physiological interpretation and clinical use","volume":"93","author":"Electrophysiology TF","year":"1996","journal-title":"Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology.
