Abstract
Aims This study evaluates the epidemiology of headache and migraine among adolescents aged 12 to 15. Methods A school-based cross-sectional study was conducted to collect and analyze data from students in grades 7-10 over the course of one month, using a simple random sampling method. The overall number of participants in this study was 692, with an average age of 13.9 years (SD = 1.3). Descriptive measures and Fisher's exact test were computed. Multivariate regression was calculated to assess the predictors of headache and migraine. Findings. Approximately one-half of the students reported having headaches: tension-type headaches (10.3%), migraines (4.8%), and other headache types (31.5%). Moreover, girl students in the age group of 14-15 reported more headaches and migraines. Conclusion The prevalence of headache and migraine in Jordan is high and increasing as students grow older. Health education programs led by school nurses and other healthcare practitioners are urgently needed.

Abstract
Tension-type headache (TTH) is the most prevalent neurological disorder worldwide and is characterized by recurrent headaches of mild to moderate intensity, bilateral location, pressing or tightening quality, and no aggravation by routine physical activity. Diagnosis is based on headache history and the exclusion of alternative diagnoses, with clinical criteria provided by the International Classification of Headache Disorders, third edition. Although the biological underpinnings remain unresolved, it seems likely that peripheral mechanisms are responsible for the genesis of pain in TTH, whereas central sensitization may be involved in transformation from episodic to chronic TTH. Pharmacological therapy is the mainstay of clinical management and can be divided into acute and preventive treatments. Simple analgesics have evidence-based effectiveness and are widely regarded as first-line medications for the acute treatment of TTH. Preventive treatment should be considered in individuals with frequent episodic and chronic TTH, and if simple analgesics are ineffective, poorly tolerated or contraindicated. Recommended preventive treatments include amitriptyline, venlafaxine and mirtazapine, as well as some selected non-pharmacological therapies. Despite the widespread prevalence and associated disability of TTH, little progress has been made since the early 2000s owing to a lack of attention and resource allocation by scientists, funding bodies and the pharmaceutical industry.

The Epidemiology of Migraine Headache in Arab Countries: A Systematic Review. ScientificWorldJournal 2020; 2020:4790254. [PMID: 32607079 PMCID: PMC7315321 DOI: 10.1155/2020/4790254] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Accepted: 05/08/2020] [Indexed: 01/26/2023] Open
Abstract
Background Recurring migraine disorders are a common medical problem, standing among the top causes of disability and sufferings. This study aimed to evaluate epidemiological evidence to report updated estimates on prevalence, risk factors, and associated comorbidities of migraine headache in the Arab countries. Design and Setting. A systematic review was conducted at the College of Public Health and Health Informatics, Riyadh, Saudi Arabia. Methods A systematic search in electronic databases, such as PubMed and Embase, as well as manual searches with cross-referencing was performed from 1990 up to 2019. Overall, 23 included papers were rated independently by two reviewers. Studies were eligible for inclusion only if they investigated migraine headache epidemiology in any Arab country and were published in English. Results Migraine prevalence among the general population ranged between 2.6% and 32%. The estimated prevalence of migraine headache among medical university students ranged between 12.2% and 27.9% and between 7.1% and 13.7% in schoolchildren (6 to 18 years). Females were found more likely to have migraine than males. The duration of migraine attacks became shorter with increasing age, while chronic (daily) migraine showed increasing prevalence with age. The most commonly reported comorbidities with migraine included anxiety, hypertension, irritable bowel syndrome, and depression. Most common headache-triggering factors included stress, fatigue, sleep disturbances, prolonged exposure to excessive sunlight or heat, and hunger. Conclusion The prevalence and risk factors of migraine headache in Arab countries are comparable to reports from western countries. Longitudinal studies are still needed to investigate the prognosis and predictors of chronicity in the arab countries.

Abstract
BACKGROUND Studies done in Saudi Arabia showed a high prevalence of headache among university students. Limited research was done to assess the relationship between headache and psychiatric disorders. The aim of this study was to assess the prevalence and association between migraine, tension-type headache, and depression among Saudi female students in Taif University. PARTICIPANTS AND METHODS A cross-sectional study using self-administered questionnaires about headache and depression was conducted at the Taif University on 1340 female students in the academic year 2016-2017. The Beck Depression Inventory, the ID Migraine™ screening tool, and the criteria of the International Headache Society were used to investigate the depressive symptoms and headache types. RESULTS The self-reported headache prevalence was 68.4%, and the prevalence of migraine, tension-type headache (TTH), and depression was 32.5%, 29.5%, and 6.2%, respectively. The main migraine trigger was stress or anxiety; 86.6% of migraineurs had a positive family history, and only 11.9% sought medical care for headache. Of students with TTH, 61.1% reported family history and only 12.4% sought medical care. Paracetamol was the commonly used analgesic for all headache types. Medical students and students in older grades showed significantly higher levels of all headache types. Depression prevalence was significantly higher among migraineurs and students who suffered higher headache frequencies. CONCLUSION The study demonstrated a high prevalence of headache among the studied students and an association between headache and depression. The study calls for increasing awareness towards headache and the importance of seeking medical consultation. Management strategies should be planned for the observed headache and depression comorbidity.

Abstract
Background Community pharmacists are the most accessible health professionals for patients seeking advice on minor ailments and over the counter supply. Objectives To assess the management of patients seeking advice for headache in community pharmacies in Jordan. Method A cross-sectional study was conducted using simulated patient in three cities in Jordan. A trained simulated patient enacted an advice-seeking scenario for the treatment of a headache. The visits were evaluated using pre-defined criteria relating to content and communication skills. Results Of 72 community pharmacies invited, 50 (69.4%) agreed to participate. Of these, 38 (76%) pharmacies were visited. The median duration of the visit was 2 min (20 s-4 min). All visits resulted in selling a drug. Paracetamol combinations often with caffeine were recommended in over 50% of visits. Drug sale recommendations were often made without obtaining essential information about symptoms or patient medical history. Only brand names and doses were often highlighted to the simulated patient. No written information was offered. Conclusion Community pharmacies in Jordan appear not to offer adequate counseling for patients seeking advice for headache. Both counseling and communication skills are suboptimal. Exploration of factors and reasons of suboptimal practice is recommended.

Abstract
Headache is considered one of the most common complaints affecting all ages: children, adolescents, and adults. A school-based, cross-sectional study was conducted to assess primary headache among high school students aged 16-18 in Grades 11-12, over a period of 3 weeks (May 2017). A questionnaire was designed, in accordance with the International Headache Society's criteria. The Pearson's χ2 test was computed to show the differences between the variables. Nearly two thirds of the students reported having headache (19.0% tension-type headache, 8.8% migraine, and 39.0% unknown type). Nearly a quarter sought help for headache, and the most frequently used analgesic was acetaminophen (82.2%) followed by aspirin (5.1%). The current study revealed that the prevalence of headache and migraine was initially high and increased with age. Moreover, headache is one of the major public health problems among high school students. An education program conducted by school nurses and other health-care providers regarding headache and migraine is needed.

Abstract
OBJECTIVES Headache is one of the most common complaints in medicine. Epidemiological and population-based studies reported that migraine has a variable prevalence worldwide. This study was done to estimate the prevalence of migraine across various age groups in Assiut district, Egypt. METHODS This is a door-to-door study. It included 4700 randomly selected individuals. RESULTS Headache was reported in 1668 subjects (35.49%), of them, 87.65% (n = 1462) had primary headaches. Migraine prevalence was 10.51% with female-to-male ratio of 2.4:1 particularly in ages of 20-40 years. The mean age of patients was 31.46 ± 13.39 years and age at onset was 24.16 ± 12.10 years. Nearly, 63.5% had frequent attacks, 65.2% of the attacks were severe enough to stop daily activities and lasted for >1 day in 32.5% of females compared to 40.7% and 14.5% for males. Chronic or daily migraine was more in females (35.3% versus 20.7% for males). Approximately, 5.6% had chronic migraine and 1.2% had daily migraine from the start, while 24.2% had transformation from episodic to chronic migraine within 6.1 ± 4.4 years. Migraine was prevalent among those with middle educational levels and labor workers. The duration of migraine attacks was found to reduce with age but the chronic/daily migraine increased with age. Hypertension, anxiety, irritable bowel syndrome, and depression were common comorbidities with migraine. CONCLUSIONS We believe that the work done in this study is informative as it determined the actual prevalence of migraine across various age groups and the important predictors of change in the severity, duration, and frequency of migraine in our locality.

Abstract
Background and Objective. Primary headaches is a major medical concern in certain Arabic countries, for example Oman, Jordan, and Qatar. This study was aimed at increasing understanding of the prevalence of headache in Arabic countries and identifying common medications used for treatment because of the lack of research done in this field in Yemen. Methods. This is a cross-sectional observational study conducted by recruiting case-series of adults and elderly who have primary headache within the age group from 18 to 85 years. 12640 subjects received a simple explanation for the aim of the study as ethical issue. The subjects were allowed to complete a self-conducted screening questionnaire. The data were diagnosed according to the International Headache Society's diagnostic criteria (2004). Results. The results showed that 76.5% of the primary headache is prevalent at least once per year, 27.1% of the tension type headache (TTH) was the maximum percentage of type of headache, and 14.48% of the migraine headache (MH) was the minimum percentage. On the other hand, the relationship between the primary headache and age of subjects was statistically significant (P < 0.05), while between primary headache and sex was not (P > 0.05). In addition, 70.15% of the subjects said that headache attacks affected their activity of daily livings (ADL). 62.26% of the subjects used the medications without medical advice regarding their headache. 37.73% of the subjects relied on medical professionals (physicians and pharmacist) regarding analgesics use. The most common agent used among the medications was paracetamol (38.4%). Others included ibuprofen, aspirin, diclofenac sodium, naproxen, mefenamic acid, ergotamine and (11.45%) were unknown agents. Conclusion. We concluded that absence of health attention from the Yemeni Community and education from the health system in the country regarding analgesics use and their potential risk led to abuse of such medications and could be a reason beyond high prevalence of headache in Yemen.

Abstract
OBJECTIVE/BACKGROUND This study aims to determine the prevalence of primary headache disorders using the second edition of international classification of headache disorders among urban slum dwellers. Headache is a common neurological disorder and one of the most common reasons for visiting the neurology clinics in Nigeria. Low socioeconomic status has been linked with primary headaches. Factors that may precipitate and sustain headaches are common in Africa especially in urban slums. There are limited population based data on the prevalence of headache from Nigeria and other African countries. METHODS A 3 phase cross-sectional descriptive study was done to survey at least 40% of the adult population (Igbos) living in an urban slum using the International Classification of Headache Disorders 2nd Edition (ICHD-I) criteria using a validated Igbo language adaptation (translation and back-translation into Igbo language) of a World Health Organization protocol for screening neurological disorders in the community. RESULTS The lifetime prevalence of headache of any type was 66.7% (95% confidence interval [CI] 64.2-69.2), significantly higher in females (70.2% [95% CI 67.0-73.4]) than in males (62.3% [95% CI 58.5-66.1]; P = .0.002). The prevalence of primary headaches was also significantly lower in males than in females (44.9% [95% CI 45.5-53.3] vs 53.2% (95% CI 49.3-57.1), P = .002). Female (52.1%) drinkers had a statistically higher prevalence of primary headaches than male drinkers (43.6%; P = .004). The prevalence of migraine was 6.4% (95% CI 5.1-7.7); 7.5% (95% CI 5.6-9.4) in females and 5% (95% CI 3.3-6.7) in males (P = .058). Migraine with aura was similar in both males and females. Migraine without aura was significantly higher in females (5.7%) than males (3.1%) (P = .022). Tension-type headache (TTH) had an overall prevalence of 13.8% (95% CI 11.3-16.3), males 12.2% (95% CI 9.7-14.7), and females 15.1% (95% CI 12.6-17.6; P = .118.) The peak decade for all primary headaches was 20-29 years for males (49.8%) and 60-69 years for females (57.5%). CONCLUSION Headache is a common health problem in an urban slum in Enugu south east Nigeria where 66.7% of participants had experienced headache in their lifetime, and 49.4% had experienced primary headaches. The prevalence of migraine and TTH were 6.4% (5% in males and 7.5% in females) and 13.8% (12.2% in males and 15.1% in females), respectively. The peak ages of migraine and tension-type headache were 30-39 and 60-69 years, respectively. The prevalence of primary headaches was significantly higher among subjects who used alcohol significantly.

Abstract
The mean global prevalence of tension-type headache (TTH) in adult is 42 %. To date, there have been no Italian studies on TTH prevalence in the adult general population. Therefore, we conducted a cross-sectional study, called PACE, aimed at detecting the prevalence of primary headaches in the city of Parma's adult general population. 904 subjects representative of Parma's adult general population were interviewed face to face by a physician of our Headache Centre. Crude past-year prevalence for definite TTH was 19.4 % (95 % CI 16.8-21.9; 18.4 %, 95 % CI 14.6-22.3 in men, and 20.1 %, 95 % CI 16.6-23.6 in women), namely, 9.0 % (95 % CI 7.1-10.8) for infrequent TTH, 9.8 % (95 % CI 7.9-11.8) for frequent TTH, and 0.6 % (95 % CI 0.1-1) for chronic TTH. Crude prevalence for probable TTH was 2.3 % (95 % CI 1.3-3.3; 2 %, 95 % CI 0.6-3.4 in men, and 2.6 %, 95 % CI 1.2-3.9 in women). Our results indicate a TTH prevalence (19.4 %) at the lower limit of data ranges for Western countries, and prevalence rates for infrequent forms (9 %) do not appear different from those of frequent forms (9.8 %).

The prevalence of headache may be related with the latitude: a possible role of Vitamin D insufficiency? J Headache Pain 2010; 11:301-7.

Abstract
According to recent observations, there is worldwide vitamin D insufficiency (VDI) in various populations. A number of observations suggest a link between low serum levels of vitamin D and higher incidence of chronic pain. A few case reports have shown a beneficial effect of vitamin D therapy in patients with headache disorders. Serum vitamin D level shows a strong correlation with the latitude. Here, we review the literature to delineate a relation of prevalence rate of headaches with the latitude. We noted a significant relation between the prevalence of both tension-type headache and migraine with the latitude. There was a tendency for headache prevalence to increase with increasing latitude. The relation was more obvious for the lifetime prevalence for both migraine and tension-type headache. One year prevalence for migraine was also higher at higher latitude. There were limited studies on the seasonal variation of headache disorders. However, available data indicate increased frequency of headache attacks in autumn–winter and least attacks in summer. This profile of headache matches with the seasonal variations of serum vitamin D levels. The presence of vitamin D receptor, 1α-hydroxylase and vitamin D-binding protein in the hypothalamus further suggest a role of vitamin D deficiency in the generation of head pain.
