Q

“Habitual Caffeinated beverage consumption and
headaches among adults with episodic migraine: A
prospective cohort study”
MR Mittleman et al. Headache,2024:64: 299-305.
 https://doi.org/10.1111/head.14673
 “Abstract
 Objective
 To examine the relationship between habitual caffeinated beverage consumption and
headache frequency, duration, and intensity in a prospective cohort of adults with episodic
migraine.
 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

A

 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.”
