“…This would have required at least one of the very few headache experts in the country to take time out from the health service in order to re-interview a subset of participants in the field; we could not justify this. The questionnaire already had a record of successful use in many countries and cultures [2, 17, 18, 30–35]. …”

BackgroundKnowledge of the epidemiology of primary headache disorders in sub-Saharan Africa (SSA) remains very limited. We performed a population-based survey in rural and urban areas of Ethiopia, using methods similar to those of an earlier study in Zambia and tested in multiple other countries by Lifting The Burden.MethodsIn a cross-sectional survey we visited households unannounced in four regions of Ethiopia: the mostly urban populations in Addis Ababa and its environs and rural populations of selected districts in Oromia, Amhara and South Nations Nationalities and People’s Regions States (SNNPRS). We used cluster-randomized sampling: within clusters we randomly selected households, and one adult member (18–65 years old) of each household. The HARDSHIP structured questionnaire, translated into the local languages, was administered face-to-face by trained interviewers. Demographic enquiry was followed by diagnostic questions based on ICHD-II criteria.ResultsFrom 2,528 households approached, 2,385 of 2,391 eligible members (1,064 [44.7%] male, 596 [25.0%] urban) consented to interview (participating proportion 99.8%). Headache in the preceding year was reported by 1,071 participants (44.9% [95% CI: 42.4–46.3]; males 37.7%, females 49.9%), and headache yesterday by 170 (7.1% [6.2–8.2]; males 45 [4.1%], females 125 [9.2%]). Adjusted for gender, age and habitation (urban/rural), 1-year prevalence of migraine was 17.7%, of tension-type headache (TTH) 20.6%, of all headache on ≥15 days/month 3.2%, and of probable medication-overuse headache (pMOH) 0.7%. The adjusted prevalence of headache yesterday was 6.4%. Very few cases (1.6%) were unclassifiable. All headache disorders were more common in females. TTH was less common in urban areas (OR: 0.3; p < 0.0001), but pMOH was very strongly associated (OR: 6.1; p < 0.0001) with urban dwelling. Education was negatively associated with migraine (OR: 0.5–0.7; p < 0.05) but (at university level) positively with pMOH (OR: 2.9; p = 0.067). Income above ETB 500/month showed similar associations: negatively with migraine (OR: 0.8; p = 0.035), positively with pMOH (OR: 2.1; p = 0.164).ConclusionsFindings for migraine and TTH in Ethiopia were quite similar to those from Zambia, another SSA country; pMOH was much less prevalent but, as in Zambia, essentially an urban problem. Primary headache disorders are at least as prevalent in SSA as in high-income western countries.

BackgroundSurveys enquiring about burden of headache over a prior period of time (eg, 3 months) are subject to recall bias. To eliminate this as far as possible, we focused on presence and impact of headache on the preceding day (“headache yesterday”).MethodsAdults (18-65 years) were surveyed from the general populations of Germany, Italy, Lithuania, Luxembourg and the Netherlands, from a work-force population in Spain and from mostly non-headache patient populations of Austria, France and UK. A study of non-responders in some countries allowed detection of potential participation bias where initial participation rates were low.ResultsParticipation rates varied between 11% and 59% (mean 27%). Non-responder studies suggested that, because of participation bias, headache prevalence might be overestimated in initial responders by up to 2% (absolute). Across all countries, 1,422 of 8,271 participants (15-17%, depending on correction for participation bias) had headache yesterday lasting on average for 6 hours. It was bad or very bad in 56% of cases and caused absence from work or school in 6%. Among those who worked despite headache, 20% reported productivity reduced by >50%. Social activities were lost by 24%. Women (21%) were more likely than men (12%) to have headache yesterday, but impact was similar in the two genders.ConclusionsWith recall biases avoided, our findings indicate that headache costs at least 0.7% of working capacity in Europe. This calculation takes into account that most of those who missed work could make up for this later, which, however, means that leisure and social activities are even more influenced by headache.

“…Comparison with Russia is of most interest because headache prevalences in China are much lower [23] and the data from the Eurolight study were not entirely population-based [24]. In Russia, 14.5 % of participants, also aged 18–65 years, reported HY [16].…”

Headache yesterday in Karnataka state, India: prevalence, impact and cost

BackgroundThe Global Campaign against Headache has pioneered evaluation of the prevalence and impact of headache on the preceding day (“headache yesterday”) as a new approach to the estimation of headache-attributed burden, avoiding recall error. We report its application in Karnataka State, southern India.MethodsIn a door-to-door survey, biologically unrelated adults (aged 18–65 years) were randomly sampled from urban and rural areas in and around Bengaluru and interviewed by trained researchers using a validated, structured questionnaire. Enquiry into headache applied ICHD-II diagnostic criteria and included questions about headache on the day preceding the interview (headache yesterday [HY]).ResultsThere were 2329 participants (participation proportion 92.6 %; males 1141 [49.0 %], females 1188 [51.0 %]; mean age 38.0 [±12.7] years; 1103 [47.4 %] from rural areas, 1226 [52.6 %] urban). HY was reported by 138 participants (males 33 [2.9 %], females 105 [8.8 %]): the 1-day prevalence of headache was 5.9 %. Mean duration of HY was 7.0 ± 8.5 h, so that 1.7 % of the population (5.9 % * 7.0/24), on average, had headache at any moment in time yesterday. Mean intensity on a scale of 1–3 was 2.0 [±0.8]. Lost productivity due to HY was reported by 83.3 % of participants with HY: 37.7 % able to do less than half of what they had planned and 13.0 % able to do nothing. Productivity loss at population level (being the productivity loss within the entire adult population, every single day, attributable to headache) was 3.0 %.ConclusionsThis method of enquiry, free from recall error, confirmed a very high level of headache-attributed burden in Karnataka: previous estimates based on 3-month recall may even have been too low. Until another study is done in the country, these are the best data for all India. They demonstrate need for action nationwide to mitigate this burden, and correct action will ultimately almost certainly be cost-saving.
