Stress is a well-known trigger for primary headache yet its impact is difficult to demonstrate in large epidemiological studies. Israeli national TV news is often referred to as the "tribal fire", as many Israelis watch national news coverage following terror attacks or military operations. We examined the association between exposure to television news and their content with headache related Emergency Department visits. This retrospective cohort study included data on daily Emergency Department visits with a chief complaint of headache in Soroka University Medical Center, during 2002-2012. Data on daily television news viewership ratings were obtained from the Israeli Audience Research Board and its content from Channel 2 headlines, the highest rated TV news program. To estimate the short-term effects of news rating during the evening news on the number of daily headache visits, we applied generalized linear mixed models. 16,693 Emergency Department visits were included in the analysis. An increase in five units of daily rating percentages was associated with increase in Emergency Department visits the following day, relative risk (RR) = 1.032, (95% CI 1.014-1.050). This association increased with the age of the patients; RR = 1.119, (95% CI 1.075-1.65) for older than 60-year-old, RR = 1.044 (95% CI 1.010-1.078) for ages 40-60 and RR = 1.000 (95% CI 0.977-1.023) for younger than 40-year-old. We did not find a specific content associated with ED visit for headache. Higher television news ratings were associated with increased incidence of Emergency Department headache related visits. We assume that especially among older persons, news viewership ratings provide an indirect estimate of collective stress, which acts as a headache trigger for susceptible subjects.
