RESUMO

There are little epidemiologic studies about headache in women; therefore, from January/1998 to June/2002 we prospectively evaluated 1101 pregnant women between 12-45 years of age, with a history of headache, at two prenatal clinics and an inpatient obstetric public hospital. The main purpose was to evaluate the presence of headache in women with previous history or new-onset headache during the current gestation, classify the findings according to the International Headache Society (IHS) criteria - 1988 and 2004, describe clinical characteristics and the outcome of headache, as well as to study the several types of headache that appeared for the first time during pregnancy. Women were interviewed with a semi-structured questionnaire during the first, second, and third gestation trimesters and immediately after delivery. All interviews were conducted by one of the authors, using the IHS classification (1988 and 2004). In 1029 women there was previous history of headache before the current pregnancy and 36 (3.4%) first experienced headache during this pregnancy. According to IHSC-1988 and 2004 criteria we found migraine in respectively 855 (83.09%) and 848/1029 (82.41%) women with pre-gestational headache. In the 36 women who initiate headache in pregnancy, migraine occurred in 22 (61,11%). There were 40 women that presented a new type of headache during pregnancy, whose more common cause was to the arterial hypertension in 22 (55%), but that also presented a prior headache, migraine in 35 (87.5%) of them (IHS - 1988 and 2004). It was possible to study the characteristics of headaches in 993 women. The most common character was throbbing in 617 (62.13%) pregnant; the most headache severity was the weak that becomes strong in 385 (38.77%) women; the most frequency headache was twice a month in 292 (29.41%); the most headache attack duration (hours) was 12 hours in 166 (17.03%) women; the headache location more common was bilateral frontal in 279 (28.1%) Among 993 women, 360 presented menstrually-related headache. Migraine crises occurred before menstruation in 55%. The outcome of headache patterns during pregnancy in 993 women with previous history of headache was improvement plus disappearance of pain in 511 (51.46%) women during first trimester, in 596 (60.02%) during second, and in 630 (63.44%) pregnant during third trimester. The 360 women with menstrually-related headache presented an improvement and disappearance during gestation (62.22% during the first trimester; 74.17% during the second trimester; 77.78% during the third trimester). The results of this study show that most of pregnant women presents headache before pregnancy, migraine, and it improves and disappears mainly during second and third trimesters. The menstrually-related headache presents larger percentile of improvement than the non-menstrual headaches, during trimesters. The most common headache in the group that presented headache for the first time during the pregnancy is migraine
