BACKGROUND: Caffeine is a commonly ascribed headache trigger in adults with migraine and clinicians may counsel patients to avoid caffeinated beverages; however, few studies have examined this association. METHODS: From March 2016 to August 2017, 101 adults with physician-confirmed episodic migraine completed baseline questionnaires, including information about caffeinated beverage consumption. For 6 weeks, they reported headache onset, duration, and pain intensity (scale 0-100) on twice-daily electronic diaries. Ninety-seven participants completed data collection. We examined associations between self-reported habitual caffeinated beverage consumption at baseline and headache outcomes prospectively captured over the following 6 weeks, adjusting for age, sex, and oral contraceptive use. RESULTS: The adjusted mean headache days per month was similar among the 20 participants reporting no habitual intake (7.1 days, 95% confidence interval [CI] 5.1-9.2), the 65 participants reporting 1-2 servings/day (7.4 days, 95% CI 6.1-8.7), and the 12 participants reporting 3-4 servings/day (5.9 days, 95% CI 3.3-8.4). Similarly, mean headache duration (no servings/day: 8.6 h, 95% CI 3.8-13.3; 1-2 servings/day: 8.5 h, 95% CI 5.5-11.5; 3-4 servings/day: 8.8 h, 95% CI 2.3-14.9) and intensity (no servings/day: 43.8, 95% CI 37.0-50.5; 1-2 servings/day: 43.1, 95% CI 38.9-47.4; 3-4 servings/day: 46.5, 95% CI 37.8-55.3) did not differ across levels of caffeinated beverage intake, though estimates were imprecise. CONCLUSIONS: We found no association between habitual caffeinated beverage intake and headache frequency, duration, or intensity. These data do not support a recommendation that patients with episodic migraine should avoid consuming caffeine. Further research is needed to understand whether deviating from usual caffeine intake may trigger migraine attacks.","journal":"Headache The Journal of Head and Face Pain","year":2024,"id":455291,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":6,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9619,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":343041,"name":"Elizabeth Mostofsky","orcid":null,"position":1,"is_corresponding":false},{"id":341268,"name":"Angeliki Vgontzas","orcid":"0000-0002-5191-1475","position":2,"is_corresponding":false},{"id":328274,"name":"Suzanne M.
