This self-matching eliminated the potential for factors such as sex, age, and other individual demographic, behavioural and environmental factors to confound the data. The researchers further matched headache incidence by day of the week, eliminating weekend versus week day habits that may also impact migraine occurrence.
Self-matching also allowed for the variations in caffeine dose across different types of beverages and preparations. "One serving of caffeine is typically defined as eight ounces or one cup of caffeinated coffee, six ounces of tea, a 12-ounce can of soda and a 2-ounce can of an energy drink," said Mostofsky. "Those servings contain anywhere from 25 to 150 milligrammes of caffeine, so we cannot quantify the amount of caffeine that is associated with heightened risk of migraine.The researchers saw no association between one to two servings of caffeinated beverages and the odds of headaches on the same day, but they did see higher odds of same-day headaches on days with three or more servings of caffeinated beverages.
However, among people who rarely consumed caffeinated beverages, even one to two servings increased the odds of having a headache that day, researchers said. "Despite the high prevalence of migraine and often debilitating symptoms, effective migraine prevention remains elusive for many patients," said Suzanne M Bertisch from BIDMC.
