Headache yesterday in Russia: its prevalence and impact, and their application in estimating the national burden attributable to headache disorders

Abstract

BackgroundEvaluation of the prevalence and impact of headache on the preceding day (“headache yesterday”; HY) is a new approach, allowing more precise estimation of headache-attributed burden without recall error. The aim of the study was to estimate the national burden attributable to headache disorders in Russia by applying measures of prevalence of HY and its impact on productivity and daily activities in the general population.MethodsWe interviewed a representative population-based sample face-to-face by visiting randomly selected households throughout Russia. We randomly selected one adult aged 18–65 years from each. We followed a structured questionnaire including diagnostic questions, enquiry into occurrence of HY and various aspects of attributed burden.ResultsParticipation rate was 74.3%. One in seven participants (14.5%; men 9.1%: women 19.3%) reported HY. Approximately half of these had one of the subtypes of headache occurring on ≥15 days/month; the remainder had episodic migraine or tension-type headache almost equally. Mean duration of headache was 6.0 ± 4.4 hours. In 88.3% headache intensity was moderate or severe (mean 2.1 on a scale 1–3) and in 73.9% HY impaired daily activity. Loss of productivity at work due to headache totalled 2.6 million person-years/year, or 4.0% of workforce capacity. This estimate exceeded by 70% a previous estimate from the same survey based on recall over the preceding 3 months. There was greater impact on other daily activities.ConclusionRecall-error-free estimation shows lost productivity every day due to headache in the Russian population is enormously high. Measures to redress these losses – effective structured health-care services supported by educational programmes – should be seen as a public-health priority while almost certainly being cost-saving.

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

“…However, China reported a very similar 1.8 % [15]. In terms of pain intensity, the mean of 2.0 on a scale of 1–3 was much the same as the 2.1 reported in Russia [16], and expected to be disabling. The consequences were seen in the per-person lost productivity of 50.7 % and population-level lost productivity of 3.0 %.…”

“…While we calculated that 1.7 % of the adult population in Karnataka had headache at any moment in time, in Russia, the proportion was much higher (3.6 % [16])–more than double. However, China reported a very similar 1.8 % [15].…”

Peculiar features of gastroesophageal reflux disease in the patients suffering from migraine

“…Результаты последнего эпидемиологического масштабного исследования распространенности го-ловной боли в России, опубликованные в 2015 г., по-казали, что 14,5% россиян трудоспособного возраста страдают ежемесячной или ежедневной головной бо-лью [9]. Выявленная высокая частота коморбидной ГЭРБ у пациентов с хронической мигренью свиде-тельствует об актуальности данной проблемы и тре-бует дальнейшего изучения.…”

Clinical significance of nausea in migraine

“…Мигрень (М) является широко распространенным заболеванием, значительно снижающим качество жизни больных и требующим больших экономических затрат. По данным популяционных исследований [1], распространенность М в России со-ставляет 15-20%, при этом в половине случаев заболевание проявляется достаточно частыми приступами головной боли, которые приводят к прогрессированию эпизодической (М) (ЭМ) в хроническую (ХМ) [2]. Несмотря на существование большого числа препаратов, рекомендованных для терапии ЭМ, успех от превентивной терапии и привержен-ность ей пациентов остаются низкими.…”
