Relation between headache in childhood and physical and psychiatric symptoms in adulthood: national birth cohort study.

OBJECTIVE To elucidate the associations between frequent headache and psychosocial factors in childhood and to determine whether such children are at an increased risk of headache, multiple physical symptoms, and psychiatric symptoms in adulthood. DESIGN Population based birth cohort study. SETTING General population. PARTICIPANTS People participating in the national child development study, a population based birth cohort study established in 1958. MAIN OUTCOME MEASURES Headache, multiple physical symptoms, and psychiatric morbidity at age 33. RESULTS Headache in childhood was associated with several psychosocial factors. Prospectively, children with frequent headache had an increased risk in adulthood of headache (odds ratio 2.22, 95% confidence interval 1.62 to 3.06), multiple physical symptoms (1.75, 1.46 to 2.10), and psychiatric morbidity (1.41, 1.20 to 1.66). The outcomes of headache and multiple physical symptoms were not accounted for by psychiatric morbidity. CONCLUSION Children with headache are at an increased risk of recurring headache in adulthood and may complain of other physical and psychiatric symptoms. Strategies for coping with psychosocial adversity in childhood may improve the prognosis in adulthood.
