Physical activity and headache: results from the Nord-Trøndelag Health Study (HUNT)

Associations of Electronic Device Use and Physical Activity with Headaches in Saudi Medical Students

Background and Objectives: Primary headaches are highly prevalent among medical students, negatively impacting their health and academic performance. Excessive electronic device use has been implicated as a risk factor, in contrast to physical activity, which may be a protective factor; however, comprehensive data are lacking, especially for Saudi medical trainees. This study aims to investigate the associations between device use, exercise, and headaches among Saudi medical students. Materials and Methods: In this cross-sectional study, 504 medical students at Jazan University completed an online survey collecting sociodemographic factors, headache characteristics/triggers, electronic device habits, exercise frequency, and headache impacts. Descriptive analyses summarized sample characteristics. Logistic regression identified predictors of 12-month headache prevalence. Results: Overall, 83% reported experiencing headaches in the past year. High headache prevalence was observed among females (86.6%) and third-year students (88.3%). Using electronic devices ≥4 h daily was associated with higher adjusted odds of headaches (OR 13.89, 95% CI 1.96-98.54) compared to ≤1 h daily. Low physical activity (exercising 1 day vs. 7 days a week) also increased headache odds (OR 3.89, 95% CI 1.61-9.42). Headaches impairing productivity (OR 4.39, 95% CI 2.28-8.45) and exacerbated by exercise (OR 10.37, 95% CI 2.02-53.35) were further associated with headache susceptibility. Conclusions: Excessive electronic device use and physical inactivity appear to be modifiable risk factors for frequent headaches in Saudi medical students. Multifaceted interventions incorporating education campaigns, skills training, and support services focused on promoting responsible technology habits, and regular exercise may help mitigate headaches in this population. Robust longitudinal studies and trials are warranted to establish causal mechanisms between lifestyle factors and headaches among medical undergraduates.

Prevalence and Associated Factors of Depression among Adults Suffering from Migraine in Spain

Considering the significance of migraine and the limited amount of research conducted on its association with depression in population-based studies in Spain, this study aimed to determine the prevalence and change of depression from 2017 to 2020 among adults with migraine in Spain and to analyze the sociodemographic and health-related variables linked to depression in migraine sufferers. A cross-sectional study on 5329 adults with migraine from the Spanish National Health Survey 2017 and the European Health Survey in Spain 2020 was performed. Binary logistic regression was used to examine the factors related to depression. A total of 26.32% of people with migraine suffered from depression. No significant changes in that prevalence between 2017 and 2020 were observed. The risk factors associated with depression included being between the ages of 25 and 44 (p = 0.018), being separated or divorced (p = 0.033), being unemployed (p < 0.001), not engaging in recreational physical activity (p = 0.016), perceiving one's health as average, poor, or very poor (p < 0.001), experiencing moderate to severe pain in daily activities (p = 0.011, p = 0.004, p < 0.001, respectively), and having 1-2 or ≥3 chronic conditions (p = 0.003, p < 0.001, respectively). Conversely, being married (p = 0.001) and alcohol consumption (p = 0.007) were identified as protective factors.

Migraine and obesity: what is the real direction of their association?

INTRODUCTION

In recent decades, studies have addressed the issue of how migraine and obesity are related and have suggested obesity as a risk factor for migraine headache. However, the exact direction of this relationship remains under debate. In this review, the authors summarize the evidence that have suggested migraine as a risk factor for obesity and overweightness.

AREAS COVERED

This article reviews the results of the previous research published on PubMed and Scopus databases (from 2000 to 2020) concerning the association between migraine and obesity to determine the actual direction of their association. Special attention has been given to the common mechanistic pathways involved in the pathophysiology of migraine and obesity.

EXPERT OPINION

The majority of research conducted thus far has considered obesity as a risk factor for migraine. However, because of the cross-sectional design of available research, we cannot be certain of the proposed direction of this association. There is evidence supporting the hypothesis that obesity can serve as a consequence of migraine through the effects of neuropeptides, inflammatory mediators, adipokines, gut microbiota and modifications in eating behavior and lifestyle. However, the real direction of the relationship between migraine and obesity should be further investigated in large prospective studies.

Relationship between Self-Efficacy and Headache Impact, Anxiety, and Physical Activity Levels in Patients with Chronic Tension-Type Headache: An Observational Study

Background

Chronic tension-type headache is the primary headache with the highest prevalence. The present study is aimed at analyzing the associations between patient self-efficacy and headache impact with pain characteristics, kinesiophobia, anxiety sensitivity, and physical activity levels in subjects with chronic tension-type headache.

Materials and Methods

An observational descriptive study was carried out. A total sample of 42 participants was recruited at university environment with diagnosis of tension-type headache. Headache characteristics (frequency, intensity, and duration), physical activity levels, pain related-self-efficacy, kinesiophobia, anxiety sensitivity, and headache impact were measured.

Results

The HIT-6 (61.05 ± 6.38) score showed significant moderate positive correlations with the ASI-3 score (17.64 ± 16.22; r = 0.47) and moderate negative correlations with the self-efficacy in the domains of pain management (31.9 ± 10.28; r = −0.43) and coping with symptoms (53.81 ± 14.19; r = −0.47). ASI-3 score had a negative large correlation with self-efficacy in the domains of pain management (r = −0.59), physical function (53.36 ± 7.99; r = −0.55), and coping with symptoms (r = −0.68). Physical activity levels showed positive moderate correlations with the self-efficacy in the domain of physical function (r = 0.41). Linear regression models determined that the self-efficacy and anxiety sensitivity with showed a significant relationship with the HIT-6 score (R² = 0.262; p = 0.008) and with the ASI-3 score (R² = 0.565; p < 0.001). In addition, no correlations were found between pain intensity, duration or frecuency with psychosocial factors, or headache impact.

Conclusions

The present study showed that patients with chronic tension-type headache had a great negative impact on daily tasks and physical activity levels, which were associated with higher anxiety levels and lower self-efficacy.

Lifestyle impact on migraine during home confinement

Background

The COVID-19 lockdown has influenced people lifestyle, behaviour, physical activity (PA), and working habits as well as, possibly, migraine. The aim of the study was to assess the impact of lockdown on the burden of migraine attacks during COVID-19 lockdown.

Methods

Patients were interviewed, and data about demographics, PA, daily behaviour, working habits, disability (HIT-6) and characteristics of migraine and drugs consumption were compared between the first month of the lockdown in Italy (March 2020), and a reference month prior the lockdown (January 2020).

Results

37 patients were analysed, classified as migraine without aura (MwoA) (n = 26) and migraine with aura (MwA) plus migraine with and without aura (MwA/MwoA) (n = 11). During the lockdown, a greater proportion of patients with insufficient PA (65% vs 31%; p = 0.012) were found. Reduced mean headache duration [3 h, (2–12) vs 2 h (1–8); p = 0.041] and HIT score [59 (51–63) vs 50 (44–57); p = 0.001] were found in MwoA patients during the lockdown, while no changes found in patients with MwA + MwA/MwoA.

Conclusions

Lockdown induced significant changes in PA and working habits of people with migraine and was found to be associated with improved migraine-related symptoms which might depend by different lifestyle habits.

Effects of Different Therapeutic Exercise Modalities on Migraine or Tension-Type Headache: A Systematic Review and Meta-Analysis with a Replicability Analysis

The primary aim of this study was to review the effect of exercise in comparison with a non-active treatment on pain intensity, frequency of headache episodes, headache duration, quality of life, medication use, and psychological symptoms, in patients with migraine or tension-type headache (TTH). A systematic search was conducted in various electronic databases to identify all relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of exercise interventions in patients with primary headaches were selected. Methodological quality was evaluated using the Cochrane Risk of Bias Tool and PEDro scale and qualitative analysis was based on classifying the results into levels of evidence according to the GRADE. 19 studies (2776 participants; 85% female) were included. The meta-analysis showed statistically significant differences in pain intensity for aerobic training in patients with migraine (SMD = -0.65; 95% CI = -1.07 to -0.22, very low certainty evidence) and for strength training in patients with TTH (SMD = -0.84; 95% CI = -1.68 to- -0.01, very low certainty evidence). Statistically significant differences were also found in the medication use (SMD = -0.51; 95% CI = -0.85 to -0.17, low certainty evidence). Low transparency, replicability and high risk of bias were found. Aerobic training has a small to moderate clinical effect on pain intensity and medication use on migraine patients, with very low to low certainty of evidence. Strength training showed a moderate clinical effect with very low quality of evidence in patients with TTH. Exercise could be considered as clinically relevant for the management of patients with primary headaches, but the presence of low certainty of evidence and low transparency and replicability limited its clinical application. PERSPECTIVE: This article presents current evidence about exercise interventions in patients with primary headaches, including migraine and tension-type headache. Existing findings are reviewed, and relevant data are provided on the effectiveness of each exercise modality, as well as its certainty of evidence and clinical applicability.

A Prospective Real-World Study Exploring Associations Between Passively Collected Tracker Data and Headache Burden Among Individuals with Tension-Type Headache and Migraine

Introduction

Prevalence and burden of headache disorders in real-world settings is relatively unstudied. We explored the associations between passively collected activity data, headache burden, and quality of life in headache sufferers.

Methods

Data from wearable activity tracking devices and daily short questionnaires were collected over 12 weeks to assess occurrence of headache, activity, quality of life and self-rated health. Variables were analyzed using a series of mixed-effects models and stratified based on headache type. Multiple linear and logistic regressions were used to analyze treatment preferences.

Results

Behaviors inferred from activity tracker data suggested that individuals slept more, had reduced physical activity, and had lower maximum heart rate on days with headache. As headache-specific impact on quality of life increased, activity and maximum heart rate decreased and sleep increased. Headache days with higher self-rated health were associated with less napping, higher step count and maximum heart rate, correlating with increased activity. Migraineurs experienced greater burden in everyday life compared with tension-type headache sufferers.

Conclusion

This study adds to existing evidence that activity trackers can be used to quantify headache burden in real-world settings and aid in understanding symptom management.

Mental pain and pain-proneness in patients with migraine: results from the PAINMIG cohort-study

BACKGROUND

Pain has been qualified under four categories: nociception, perception of pain, suffering, and pain behaviors. Most of the literature on migraine has devoted attention to the first two. The aim of the present cohort study was to investigate patients with migraine enrolled at a tertiary care unit to study suffering and mental pain and identify potential risk factors for migraine.

METHODS

An observational cross-sectional study was carried out on patients with chronic migraine (CM) and episodic migraine (EM), and healthy subjects (HS). The three groups were matched for age and sex. A comprehensive assessment of migraine disability, pain, psychiatric disorders, psychosomatic syndromes, depressive and anxious symptoms, euthymia, psychosocial variables, mental pain, and pain-proneness (PP) was performed.

RESULTS

Three hundred subjects were enrolled (100 CM, 100 EM, and 100 HS). Based on the multiple regression analyses, those presenting PP (social impairment: odds ratio [OR] = 3.59, 95% confidence interval [CI] = 1.14-11.29; depressive symptoms: OR = 3.82, 95% CI = 1.74-8.41) were more likely to be CM than HS. Those with higher levels of PP (social impairment: OR = 4.04, 95% CI = 1.60-10.22; depressive symptoms: OR = 2.02, 95% CI = 1.26-3.24) were more likely to be EM than HS. Those presenting higher levels of mental pain were more likely to be CM than EM (OR = 1.45, 95% CI = 1.02-2.07).

CONCLUSION

Migraine is an unpleasant sensory and emotional experience associated with psychosocial manifestations that might contribute to the level of suffering of the individuals. Mental pain resulted to be the variable that most differentiated patients with CM from EM.

Headache disability, lifestyle factors, health perception, and mental disorder symptoms: a cross-sectional analysis of the 2013 National Health Survey in Brazil

OBJECTIVE

To evaluate the past 2-week headache disability and explore its association with lifestyle factors, health perception, and mental disorder symptoms in the PNS 2013 survey.

BACKGROUND

The prevalence of headache disorders has been associated with lifestyle factors, mental disorders, and health perception. However, less is known regarding their influence on headache-related disability.

METHODS

In a cross-sectional analysis, chi-squared tests and logistic regression models computed the associations between headache-related disability (defined as days lost from work, school, or household chores in the past 2 weeks) and the variables of interest, compared to other disease-related disabilities groups or no day lost group. The adjusted models controlled for the effects of age, sex, income, and educational levels.

RESULTS

In the sample aged ≥ 18 years (n = 145,580), 10,728 (7.4%) participants reported any disease-related disability in the past 2 weeks (median interquartile range (IQR) for age = 47 (33-59) years, 62% women), with the median (IQR) days lost = 5 (2-14). Headache disability represented 5.3% (572/10,728) of all diseases, constituting the 4th most prevalent disease-related disability [median (IQR) days lost = 3 (3-4)]. Among people aged 18-25 years, headache disorders ranked 2nd as the most prevalent disability (13%), headache-related disability positively associated with physical inactivity, poorer health perception, and frequent mental disorders symptoms, and negatively associated with overweight, obesity, and alcohol consumption.

CONCLUSION

Headache disability represents a leading cause of disease-related disability in Brazil and associates with unhealthy lifestyle factors, poorer health perception, and frequent mental disorder symptoms.

Physical inactivity and headache disorders: Cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

BACKGROUND

Physical inactivity has been linked to headache disorders but estimates based on the current World Health Organization physical activity guidelines are unknown.

OBJECTIVE

To test the associations between headache disorders and physical inactivity in the ELSA-Brasil cohort.

METHODS

In a cross-sectional analysis, linear (continuous variables) and logistic regression models (categorical variables) tested the associations of physical activity levels in the leisure time, commuting time, and combined leisure time physical activity + commuting time physical activity domains with headache disorders, adjusted for the effects of sociodemographic data, cardiovascular risk variables, psychiatric disorders, and migraine prophylaxis medication.

RESULTS

Of 15,105 participants, 14,847 (54.4% women) provided data on physical activity levels and headache. Higher physical activity levels (continuous values) in the leisure time physical activity domain associated with lower migraine and tension-type headache occurrence and lower headache attack frequency, while in the commuting time physical activity domain it associated with more frequent headache attacks. Compared to people who met World Health Organization physical activity levels in the leisure time physical activity or combining leisure time physical activity + commuting time physical activity domains (i.e. ≥150 min.wk^-1 of moderate and/or ≥75 min.wk^-1 of vigorous physical activity), physical inactivity associated with higher migraine occurrence, while somewhat active (i.e. not meeting World Health Organization recommendations) associated with higher migraine and tension-type headache occurrence. Physical inactivity in the commuting time physical activity domain associated with higher tension-type headache in men and lower migraine in women. Physical inactivity within vigorous leisure time physical activity intensity, but not moderate leisure time physical activity, associated with higher migraine, mostly in women. Finally, physical inactivity associated with higher headache attack frequency regardless headache subtype.

CONCLUSION

Physical inactivity and unmet World Health Organization physical activity levels associate with primary headaches, with heterogeneous associations regarding headache subtype, sex, physical activity domain/intensity, and headache frequency in the ELSA-Brasil study.

Effectiveness of Exercise and Manual Therapy as Treatment for Patients with Migraine, Tension-Type Headache or Cervicogenic Headache: An Umbrella and Mapping Review with Meta-Meta-Analysis

The aim of the study was to perform a mapping and umbrella review with meta-meta-analysis (MMA) to synthesise and critically evaluate the effectiveness of manual therapy (MT) and aerobic exercise (AE) in relation to pain intensity, frequency, disability and quality of life in patients with migraines, tension-type headaches (TTH) and cervicogenic headaches (CGH). A systematic search was conducted in PubMed, PEDro, Scielo and Google Scholar up to December 2020. A total of 18 articles met the inclusion criteria, and only 8 were included in the quantitative analysis. The MMA showed results in favour of the interventions in terms of pain intensity and quality of life in migraine, TTH and CCH. Data were also in favour of the intervention in terms of pain frequency in migraine and in terms of disability in TTH. However, there were no significant effects on pain frequency in TTH and CGH. The results showed moderate evidence to suggest that AE reduces pain intensity in patients with migraine. In addition, the evidence in favour of MT or a mixed intervention (including therapeutic exercise) was also moderate in terms of reducing pain intensity in patients with TTH.

Multinational descriptive analysis of the real-world burden of headache using the Migraine Buddy application

BACKGROUND AND PURPOSE

A large proportion of headache sufferers do not routinely seek medical care. App-based technologies permit the collection of real-world data over time and between countries that can help assess true burden of headache. This study used a mobile phone application to collect information on the real-world burden of self-diagnosed headache and to describe its impact on daily life in headache sufferers who do not routinely seek medical advice.

METHODS

This retrospective, non-interventional, cross-sectional study analysed self-reported data from users of the 'Migraine Buddy' app. The main objective was to describe self-reported characteristics of headache and migraine (triggers, duration, frequency), treatment patterns and impact on daily activity in headache sufferers from Australia, Brazil, France, Germany and Japan. Data including demographics, self-diagnosed episode type (headache/migraine), duration, potential triggers and impact on daily activity are reported. All analyses were exploratory and performed per country.

RESULTS

Self-reported data were collected from 60,474 users between August 2016 and August 2018. Approximately 90% of users were females; >60% were aged 24-45 years. Over one-third of users reported having two to five episodes of headache or migraine per month; impact included impaired concentration, being slower and missing work or social activities. Variations across countries were observed; within countries, episode characteristics were very similar for self-diagnosed headache versus migraine.

CONCLUSIONS

Headache tracking was used to describe the experience, impact and self-management approaches of migraine and headache sufferers in a real-world setting. Headache disorders present a range of important issues for patients that deserve more study and reinforce the need for better approaches to management.

Social Distancing in Chronic Migraine during the COVID-19 Outbreak: Results from a Multicenter Observational Study

BACKGROUND

The restrictions taken to control the rapid spread of COVID-19 resulted in a sudden, unprecedented change in people's lifestyle, leading to negative consequences on general health. This study aimed to estimate the impact of such changes on migraine severity during 2020 March-May lockdown.

METHODS

Patients affected by migraine with or without aura, diagnosed by expert physicians, completed a detailed interview comprehensive of: assessment of migraine characteristics; measure of physical activity (PA) levels; measure of the intake frequency of main Italian foods; the Insomnia Severity Index (ISI) questionnaire investigating sleep disorders.

RESULTS

We included 261 patients with a mean age of 44.5 ± 12.3 years. During social distancing, 72 patients (28%) reported a headache worsening, 86 (33%) an improvement, and 103 (39%) a stable headache frequency. A significant decrease of the PA levels during COVID-19 quarantine in the whole study sample was observed (median total metabolic equivalent task (METs) decreased from 1170 to 510; p < 0.001). Additionally, a significant difference was reported on median ISI scores (from 7 to 8; p < 0.001), which were increased in patients who presented a stable or worsening headache.

CONCLUSIONS

Our study confirmed that the restrictions taken during the pandemic have affected the practice of PA levels and sleep quality in migraine. Hence, PA and sleep quality should be assessed to find strategies for an improvement in quality of life.

Exercise in Treatment of Migraine Including Chronic Migraine

PURPOSE OF REVIEW

With this review, we aimed to investigate the effect of exercise on migraine and explored the possibility of exercise as a treatment option for migraine.

RECENT FINDINGS

A close association of physical activity and exercise with migraine has been reported in clinical and population-based studies. Recent randomized controlled trials investigating the effect of aerobic exercise as a migraine-preventive treatment have revealed a notable improvement in migraine symptoms. Data on the effect of anaerobic exercise and exercise for flexibility, coordination, and relaxation on migraine are currently insufficient to make any recommendations. Possible pathways for the attenuation of migraine by exercise include the endogenous opioid and cannabinoid systems, brain-derived neurotrophic factor, inflammation, and behavioral/psychological factors. Regarding efficacy, side effects, and health benefits, aerobic exercise is a potentially beneficial strategy in the preventive treatment of migraine. Further studies are needed to delineate an evidence-based exercise program for migraine treatment.

Lifestyle Modifications to Help Prevent Headache at a Developmental Age

Headache is the world's seventh most significant cause of disability-adjusted-life in people aged between 10 and 14 years. Therapeutic management is based on pharmacological approaches and lifestyle recommendations. Many studies show associations between each migraine-promoting lifestyle, behavioral triggers, frequency, and intensity of headaches. Nevertheless, the overall aspects of this topic lack any definitive evidence. Educational programs advise that pediatric patients who suffer from migraines follow a correct lifestyle and that this is of the utmost importance in childhood, as it will improve quality of life and assist adult patients in avoiding headache chronicity, increasing general well-being. These data are important due to the scarcity of scientific evidence on drug therapy for prophylaxis during the developmental age. The "lifestyle recommendations" described in the literature include a perfect balance between regular sleep and meal, adequate hydration, limited consumption of caffeine, tobacco, and alcohol, regular physical activity to avoid being overweight as well as any other elements causing stress. The ketogenic diet is a possible new therapeutic strategy for the control of headache in adults, however, the possible role of dietary factors requires more specific studies among children and adolescents. Educational programs advise that the improvement of lifestyle as a central element in the management of pediatric headache will be of particular importance in the future to improve the quality of life of these patients and reduce the severity of cephalalgic episodes and increase their well-being in adulthood. The present review highlights how changes in different aspects of daily life may determine significant improvements in the management of headaches in people of developmental age.

Prospective cohort study of routine exercise and headache outcomes among adults with episodic migraine

OBJECTIVE

To evaluate the association of routine exercise with headache frequency, intensity, and duration among adults with episodic migraine (EM).

BACKGROUND

A comprehensive management plan for EM must aim at reducing disability and cost of care; to do so requires optimizing acute and preventive medications, and behavior changes. Prophylactic medication use is associated with adverse events and contraindications with comorbidities. Aerobic exercise is reported to decrease migraine frequency. However, no study has evaluated a potential synergistic relation between regular exercise and preventive medication use among patients with EM.

DESIGN AND METHODS

This was a secondary analysis of data from a prospective cohort study of adults with EMs. In that study, adults with EM (using International Classification of Headache Disorders-3 criteria confirmed by study physicians) were recruited from three academic medical centers in Boston, MA. At baseline, participants provided information on exercise, clinical and demographic characteristics, and lifestyle behaviors. We prospectively collected daily information on headaches and health behavior over at least 6 weeks using electronic questionnaires from 94 participants. We assessed the association between baseline self-reported moderate-vigorous exercise at least three times per week, at baseline, and prospectively recorded headache frequency, intensity, and duration. We further assessed whether these associations differed by the prevalent use of prophylactic migraine medication.

RESULTS

Data from 94 of 98 eligible participants were used in the analysis as 4 participants had missing data on routine exercise frequency or intensity at baseline. On average, patients who reported moderate-vigorous exercise at least three times per week at enrollment had 1.5 fewer headache days per month (-1.5 headache days/month; 95% confidence interval [CI] -3.1 to 0.1) compared to less exercise; this was not statistically significant (p = 0.066). The association between exercise and headache days per month varied by baseline use of migraine prophylaxis (p-value of interaction = 0.009). Among those who reported regular use of migraine prophylaxis, a report of moderate-vigorous exercise at least three times per week was associated with 5.1 fewer headache days (-5.1: 95% CI -8.2 to -2.0; p = 0.001) compared to those who reported lower levels of exercise. However, among those not using migraine prophylaxis, we observed only 0.4 fewer headache days per month (-0.4: 95% CI -2.2 to 1.3; p = 0.636) associated with moderate-vigorous exercise at least three times/week, a result that was not statistically significant. There was no association of self-reported moderate-vigorous exercise at least three times a week with headache intensity or duration.

CONCLUSION

In patients with EM, those who reported moderate-vigorous exercise at least three times per week had fewer headache days per month, though not statistically significant. This association was significantly stronger in those who used prophylactic medication for migraines. Exercise appeared not to be associated with the severity or duration of headaches. Routine moderate-vigorous exercise may be an important adjunctive strategy for improving headache burden in patients eligible for migraine prophylaxis.

Prevalence and risk factors of migraine and non-migraine headache in older people - results of the Heinz Nixdorf Recall study

BACKGROUND

The prevalence of migraine and non-migraine headache declines with age.

METHODS

Data from the third visit (2011-2015) of the population-based Heinz Nixdorf Recall study were analysed (n = 2038, 51% women, 65-86 years). Possible risk factors for headache activity (obesity, education, smoking, sports, alcohol, partnership status, living alone, having children, sleep quality, depression, hypertension, diabetes mellitus, stroke, coronary heart disease, medication), and headache symptoms were assessed. We estimated the lifetime prevalence and the prevalence of current active headache of migraine with and without aura, and non-migraine headache. The associations between possible risk factors and headache activity (active vs. inactive) were estimated by age and sex-adjusted odds ratios and 95% confidence intervals (OR [95% CI]) using multiple logistic regression.

RESULTS

The lifetime prevalence of migraine was 28.6% (n = 584). One hundred and ninety-two (9.4%) had still-active migraine, 168 (3.5%) had migraine with aura, and 416 (5.9%) had migraine without aura. One hundred and sixty-eight (8.2%) had "episodic infrequent migraine, 0-8 headache days/month", 10 (0.5%) had "episodic frequent migraine, 9-14 headache days/month", and five (0.2%) had "chronic migraine, ≥15 headache days/month". Overall, 10 (0.5%) had "chronic headache, any headache on ≥15 days/month". Female gender and younger age were the most important associated migraine risk factors. Depression (1.62 [1.06; 2.47]) and poor sleep (1.06 [1.00; 1.12]) were associated with migraine and headache activity in general. Antihypertensives were associated with headache remission (0.80 [0.64; 1.00]). Additionally, undertaking less sports (0.72 [0.51; 1.03]) was associated with higher migraine activity.

CONCLUSIONS

Headaches and migraines are not rare in the older population. They are related to mood and sleep disturbance, and migraine even to less physical activity. Antihypertensives are related to headache remission.

Migraine and Sport in a Physically Active Population of Students: Results of a Cross-Sectional Study

OBJECTIVE

In this study, we explored the relationship between migraine and sport in a physically active population of students, analyzing the risk of migraine among sporty students.

BACKGROUND

The relationship between sport and migraine is controversial; moreover, several studies report on sport as a migraine trigger, but there is evidence that physical activity could have a relevant role in migraine prevention.

METHODS

A cross-sectional survey was conducted using the validated ID-migraine questionnaire including specific demo-anthropometric (gender, age, weight, height) and sports variables on a potentially active student population of the University of Palermo. Evaluation in putative migraine subjects of clinical features and disability was explored through the administration of the Italian version of the Migraine Disability Assessment Scale. Statistical analyses were performed using univariate and logistic regression analyses.

RESULTS

Three hundred and ninety-three out of 520 students (210 F, mean age: 23.5 ± 0.7 years; 183 M; mean age: 20.5 ± 0.7 years) participated in this study. Migraine screened positive in 102 subjects (26.0%) and its prevalence was significantly higher among females (P < .001). An increased risk of migraine was found in females, and a protective effect of sport on the risk of migraine among females, but not among males.

CONCLUSIONS

The role of exercise in migraine is still unclear. This study supports a protective role of sport in migraine reporting a protective effect in females. Further studies are needed to deepen the association between sport and migraine.

Physical exercise enhances vulnerability to migraine headache associated with CGRP up-expression in trigeminal nucleus caudalis of stressed rats

OBJECTIVES

There is conflicting evidence on the effect of physical exercise on migraine development. Present study investigated the impact of treadmill exercise on migraine - associated symptoms and changes in calcitonin gene-related peptide (CGRP) expression in rats with and without maternal deprivation stress (MD).

METHODS

Two days after birth, the male Wistar pups were randomly divided into four groups (n = 6) as follows: intact, exercise, MD, and MD plus exercise. The animals in the MD groups were separated from their dams 4 h per day for 2 weeks. At 8 weeks of age, the rats were exercised on a motor-driven treadmill for 4 weeks. Then, nitroglycerin (NTG) (5 mg/kg/IP) was used to induce migraine and pain-related symptoms were recorded for 90 min. NTG-related thermal hyperalgesia was measured by tail flick and hot plate methods. Finally, immunofluorescence staining of CGRP in trigeminal subnucleus caudalis (Vc) was performed.

RESULTS

NTG - produced a significant headache symptoms and thermal hypersensitivity, which were aggravated following physical exercise in stressed or unstressed groups. Besides, NTG administration increased CGRP expression in the Vc of rats. Such effect was overpowered by treadmill running only in rats exposed to MD stress.

CONCLUSION

These findings highlight the worsening effects of treadmill exercise for migraine in rats with and without MD stress. However, inflammatory response can further exacerbate in stressed rats.

Does intensive interdisciplinary pain treatment improve pediatric headache-related disability?

Purpose: To examine the effectiveness of intensive interdisciplinary pain treatment for improving disability in children with chronic headache using the International Classification of Functioning, Disability and Health model as a conceptual framework for disability assessment.Materials and methods: Children with chronic headache (n = 50; ages 10-19 years; 62% female) attended an intensive interdisciplinary pain treatment program 8 h/day, 5 times/week for 2-7 weeks. Disability measures were administered at admission, discharge, and 6-8 week follow-up. Disability outcomes were analyzed retrospectively. Wilcoxon signed rank tests and Friedman's analyses of variance were used to compare scores across two and three longitudinal time points, respectively.Results: After rehabilitation, disability reduced on the Headache Impact Test-6 from severe impact at admission to some impact at follow-up (p < 0.001). Median time on the modified Bruce protocol increased from 13.1 min (interquartile range = 12.6-14.1) to 14.4 min (interquartile range = 12.9-16.3), p < 0.001, with gains maintained at follow-up. Improvements in pain and disability were associated with improvements in school participation.Conclusions: Findings of this study support the effectiveness of intensive interdisciplinary pain treatment for improving disability in children with chronic headache.Implication for rehabilitationIntensive interdisciplinary pain treatment is effective for improving pain and disability in children with chronic headaches.Application of the ICF model to disability assessment suggests that children with chronic headaches may experience significant disability, even when standardized assessments of physical capacity are normal.The modified Bruce protocol, Pediatric Evaluation of Disability Inventory - Computerized Adaptive Tests, and Headache Impact Test-6 appear particularly valuable in understanding the nature of disability in children with chronic headaches.

The effectiveness of an aerobic exercise training on patients with neck pain during a short- and long-term follow-up: a prospective double-blind randomized controlled trial

Objective:

To examine the effect of adding aerobic exercise (AE) to neck-specific exercise treatment for patients with neck pain (NP) to reduce pain and disability.

Design:

A prospective multicentre randomized controlled trial.

Setting:

Physiotherapy outpatient clinics.

Subjects:

Patients with nonspecific NP.

Intervention:

Patients with NP were randomly assigned to six weeks of neck-specific exercise with and without the addition of AE.

Measures:

Patients were classified as having a successful or non-successful outcome according to the Global Rating of Change (GROC). Outcome measures included Visual Analogue Scale (VAS), Neck Disability Index (NDI), Fear Avoidance Beliefs Questionnaire (FABQ) and cervicogenic headache. Assessments were performed at six-week, and three- and six-month follow-ups.

Results:

A total of 139 participants (mean age: 54.6 ± 10.5 years) were recruited ( n = 69 AE, n = 70 control). According to GROC, 77.4% of the AE group reported a successful outcome at six months vs. 40% in the control group ( P < 0.001). There was a significant reduction in VAS from baseline to six months in the AE vs. control group 6.73 (±1.69) to 1.89 (±1.37) vs. 6.65 (±1.67) to 3.32 (±1.82), respectively ( P  < 0.001). Significant improvements were also obtained for NDI and FABQ from baseline to six weeks in the AE group: NDI from 16.10 (±4.53) to 7.78 (±4.78) vs. 17.01 (±4.84) to 11.09 (±5.64) in the control group ( P = 0.003); FABQ from 33.53 (±9.31) to 20.94 (±841) in the AE vs. 33.45 (±10.20) to 26.83 (±10.79) in the control group ( P < 0.001). The AE group also demonstrated significant reduction in cervicogenic headache from baseline to six months ( P = 0.003).

Conclusion:

Adding AE to long-term neck-specific exercises is an effective treatment for reducing NP and headache in patients with NP.

Time trends of major headache diagnoses and predictive factors. Data from three Nord-Trøndelag health surveys

AIMS

The primary aim of this study was to investigate time trends of major headache diagnoses using cross-sectional data from two population-based health surveys. In addition, we aimed to perform a longitudinal assessment of baseline characteristics and subsequent risk for having headache at 22-years' follow-up among those participating in three health surveys.

METHODS

Data from the Nord-Trøndelag Health Study (HUNT) performed in 1995-1997 (HUNT2), 2006-2008 (HUNT3) and 2017-2019 (HUNT4) were used. The 1-year prevalence time trends of major headache diagnoses were estimated among 41,460 participants in HUNT4 and among 39,697 participants in HUNT3, two surveys with identical headache questions. 16,118 persons participated in all three surveys, and among these, a Poisson regression was used to evaluate health-related baseline information in HUNT2 and the risk ratios (RRs) with 95% confidence interval (CIs) of consistently reporting headache during follow-up.

RESULTS

Compared with the 1-year prevalence in HUNT3, a higher proportion of participants in HUNT4 had tension-type headache (20.7% vs. 15.9%, p < 0.001), whereas a lower 1-year prevalence was found for migraine (11.1% vs. 12.0%, p < 0.001) and medication overuse headache (MOH) (0.3% vs. 1.0%, p < 0.001). Participants in the age group 20-39 years at baseline nearly three times increased risk (RR = 2.8, 95% CI 2.5-3.1) of reporting headache in HUNT2, HUNT3 and HUNT4 than persons aged 50 years or more. Female sex, occurrence of chronic musculoskeletal complaints and high score of depression or anxiety at baseline doubled the risk of having headache in all three surveys.

CONCLUSIONS

The 1-year prevalence of migraine and MOH was lower in HUNT4 than in HUNT3. Young age, female sex, and occurrence of musculoskeletal complaints and high score of anxiety and/or depression were all associated with substantially increased risk of reporting headache in all three surveys.

Evaluation and Treatment of Primary Headaches in Adolescents

Headache is a common episodic and chronic pain syndrome in adolescents. Evaluation of headaches in primary care requires a comprehensive assessment including lifestyle behaviors and physical examination, as well as an understanding of when to pursue appropriate testing. Primary headache disorders seen in adolescents include migraine and tension-type headache. Pharmacologic management for primary headache includes both acute and prophylactic treatment strategies.

Circulating Biomarkers in Migraine: New Opportunities for Precision Medicine

Background:

Migraine is the most common neurological disorder and the second most disabling human condition, whose pathogenesis is favored by a combination of genetic, epigenetic, and environmental factors. In recent years, several efforts have been made to identify reliable biomarker(s) useful to monitor disease activity and/or ascertain the response to a specific treatment.

Objective:

To review the current evidence on the potential biological markers associated with migraine.

Methods:

A structured search of peer-reviewed research literature was performed by searching major publications databases up to December 2017.

Results:

Several circulating biomarkers have been proposed as diagnostic or therapeutic tools in migraine, mostly related to migraine’s inflammatory pathophysiological aspects. Nonetheless, their detection is still a challenge for the scientific community, reflecting, at least in part, disease complexity and clinical diagnostic limitations. At the present time, calcitonin generelated peptide (CGRP) represents probably the most promising candidate as a diagnostic and/or therapeutic biomarker, as its plasma levels are elevated during migraine attack and decrease during successful treatment. Other molecules (including some neuropeptides, cytokines, adipokines, or vascular activation markers) despite promising, do not possess the sufficient prerequisites to be considered as migraine biomarkers.

Conclusion:

The characterization of migraine-specific biomarkers would be fundamental in a perspective of precision medicine, enabling risk assessment and tailored treatments. However, speculating on the clinical validity of migraine biomarkers may be premature and controlled clinical trials are presently needed to investigate both the diagnostic and therapeutic value of these biomarkers in migraine.

Cardiovascular fitness and risk of migraine: a large, prospective population-based study of Swedish young adult men

OBJECTIVES

To examine the longitudinal relationship between cardiovascular fitness in young adult men and future risk of migraine and to estimate eventual differential effects among categories of body mass index (BMI) and blood pressure.

DESIGN

National, prospective, population-based cohort study.

SETTING

Sweden 1968-2014.

PARTICIPANTS

18-year-old Swedish men (n=1 819 828) who underwent mandatory military conscription examinations during the years 1968-2005.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome was the first dispensation of prescribed migraine-specific medication, identified using the Swedish Prescribed Drug Register. The secondary outcome was documented migraine diagnosis from the Swedish National Hospital Register.

RESULTS

During follow-up, 22 533 men filled a prescription for migraine-specific medication. After confounding adjustment, compared with high cardiovascular fitness, low and medium fitness increased the risk of migraine-specific medication (risk ratio (RR)_low: 1.29, 95% CI 1.24 to 1.35; population attributable fraction: 3.6%, 95% CI 1.7% to 5.3% and RR_medium: 1.15, 95% CI 1.12 to 1.19; population attributable fraction: 8.0%, 95% CI 4.0% to 11.7%). To assess potential effect measure modification, stratified analyses of these association by levels of BMI and blood pressure showed that lower fitness levels increased risk of migraine across all groups except among underweight men or men with high diastolic blood pressure.

CONCLUSIONS

Young men with a lower cardiovascular fitness had a higher long-term risk of developing pharmacological prescription-requiring migraine. This study contributes with information regarding risk factors for migraine in men, an understudied population in migraine research.

Sports, physical activity and headache in the classical age: historical descriptions from the first sports textbook, "De arte gymnastica", by Girolamo Mercuriale

BACKGROUND AND OBJECTIVES

The relationship between physical activity, sports and headache presents a growing interest, testified by numerous papers recently published. The correlation between headache and sporting activities or physical exercise dates back to the classical age. We aim at promoting the development of more studies focused on the relationship between headache and physical activity.

METHODS

We analysed the book "De arte gymnastica", written by Girolamo Mercuriale (Forlì, Italy, 1530-1606), and considered the first "sports medical textbook". We discuss these classical literature findings in the light of the International Classification of Headache Disorders, 3rd edition.

RESULTS

The Author's work derives from the systematic revision of Greek, Roman and Arabic literatures about the matter. Despite some references to inveterate headaches or cold-related pains, Mercuriale does not gather specific clinical characterisations of different types of headache. However, interestingly, he reports detailed descriptions of how the same sport, or the same physical activity, could cause or give relief from head pain, depending on the precise way of practising. Mercuriale summarises 18 sports or physical activities that can give relief from headache; conversely, running or heavy activities, such as boxing, appear among the 12 contraindicated sports for people suffering from headache.

CONCLUSIONS

"De arte gymnastica", by Girolamo Mercuriale, is the first textbook on sports medicine. Headache if often cited along the treatise: different sports and physical activities, or various ways of practising the same action could produce opposite effects for people suffering from headache.

The association between migraine and physical exercise

BACKGROUND

There is an unmet need of pharmacological and non-pharmacological treatment options for migraine patients. Exercise can be used in the treatment of several pain conditions, including. However, what exact role exercise plays in migraine prevention is unclear. Here, we review the associations between physical exercise and migraine from an epidemiological, therapeutical and pathophysiological perspective.

METHODS

The review was based on a primary literature search on the PubMed using the search terms "migraine and exercise".

RESULTS

Low levels of physical exercise and high frequency of migraine has been reported in several large population-based studies. In experimental studies exercise has been reported as a trigger factor for migraine as well as migraine prophylaxis. Possible mechanisms for how exercise may trigger migraine attacks, include acute release of neuropeptides such as calcitonin gene-related peptide or alternation of hypocretin or lactate metabolism. Mechanisms for migraine prevention by exercise may include increased beta-endorphin, endocannabinoid and brain-derived neurotrophic factor levers in plasma after exercise.

CONCLUSION

In conclusion, it seems that although exercise can trigger migraine attacks, regular exercise may have prophylactic effect on migraine frequency. This is most likely due to an altered migraine triggering threshold in persons who exercise regularly. However, the frequency and intensity of exercise that is required is still an open question, which should be addressed in future studies to delineate an evidence-based exercise program to prevent migraine in sufferers.

Intentional avoidance of physical activity in women with migraine

Given the benefits of habitual physical activity for migraine management and overall health, it is important to understand the reasons for low physical activity levels in those with migraine. Beliefs that physical activity can trigger and/or worsen migraine pain may contribute to low physical activity levels via intentional avoidance of physical activity, particularly of higher intensities. This study evaluated intentional avoidance of physical activity at varying intensity levels and its association with (a) leisure-time physical activity levels, (b) beliefs that physical activity will trigger and/or worsen migraine, and (c) migraine characteristics. Participants were women ( n = 100) who screened positive for migraine on the IDMigraine and completed an online survey on physical activity and migraine. The majority of the sample (78%) reported avoiding physical activity to manage migraine attacks at least once in the past month, and most reported avoidance of both moderate- and vigorous-intensity activity. Among those who reported avoidance, moderate- and vigorous-intensity physical activity was avoided on an average of 4.0 ± 2.0 and 4.1 ± 2.2 days/week, respectively. More frequent avoidance of vigorous-intensity physical activity (but not moderate-intensity) was significantly correlated with lower vigorous-intensity physical activity indicated by fewer days/week ( r = −0.28, p = 0.016) and fewer minutes/day ( r = −0.29, p = 0.011). The frequency of physical activity avoidance was significantly correlated with stronger expected likelihood that physical activity, at both intensity levels, will both trigger ( r = 0.39–0.43, p < 0.01) and worsen ( r = 0.24–0.25, p < 0.05) migraine attacks. Individuals who avoided physical activity reported a significantly higher number of migraine attacks in the past month and were more likely to have chronic migraine, compared to those who did not report avoidance. Intentional avoidance of moderate- and vigorous-intensity physical activity is a common migraine management strategy that is associated with lower levels of vigorous-intensity physical activity, stronger beliefs that physical activity will trigger or worsen migraine, and more frequent migraine attacks. Individuals with migraine who avoid physical activity may benefit from targeted intervention to address beliefs about physical activity and migraine, which has the strong potential to improve both migraine and health outcomes.

Redox Mechanisms in Migraine: Novel Therapeutics and Dietary Interventions

SIGNIFICANCE

Migraine represents the third most prevalent and the seventh most disabling human disorder. Approximately 30% of migraine patients experience transient, fully reversible, focal neurological symptoms (aura) preceding the attack. Recent Advances: Awareness of the hypothesis that migraine actually embodies a spectrum of illnesses-ranging from episodic to chronic forms-is progressively increasing and poses novel challenges for clarifying the underlying pathophysiological mechanisms of migraine as well as for the development of novel therapeutic interventions. Several theories have evolved to the current concept that a combination of genetic, epigenetic, and environmental factors may play a role in migraine pathogenesis, although their relative importance is still being debated.

CRITICAL ISSUES

One critical issue that deserves a particular attention is the role of oxidative stress in migraine. Indeed, potentially harmful oxidative events occur during the migraine attack and long-lasting or frequent migraine episodes may increase brain exposure to oxidative events that can lead to chronic transformation. Moreover, a wide variety of dietary, environmental, physiological, behavioral, and pharmacological migraine triggers may act through oxidative stress, with clear implications for migraine treatment and prophylaxis. Interestingly, almost all current prophylactic migraine agents exert antioxidant effects.

FUTURE DIRECTIONS

Increasing awareness of the role of oxidative stress and/or decreased antioxidant defenses in migraine pathogenesis and progression to a chronic condition lays the foundations for the design of novel prophylactic approaches, which, by reducing brain oxidative phenomena, could favorably modify the clinical course of migraine.

Lifestyle factors and risk of migraine and tension-type headache. Follow-up data from the Nord-Trøndelag Health Surveys 1995-1997 and 2006-2008

AIMS

The aim of this population-based historical cohort study was to investigate the influence of lifestyle factors on the risk of developing migraine or tension-type headache (TTH).

METHODS

Data from the Nord-Trøndelag Health Study performed in 1995-1997 and 2006-2008 was used. A total of 15,276 participants without headache at baseline were included. A Poisson regression was used to evaluate the associations between lifestyle factors and risk ratios (RRs) of migraine and TTH 11 years later. Precision of the estimates was assessed by 95% confidence interval (CIs).

RESULTS

Increased risk of migraine (RR 1.30, 95% CI 1.11-1.52) was found in smokers (past or current) compared to those who had never smoked. Hard physical exercise 1-2 hours per week reduced the risk of migraine (OR 0.71, 95% CI 0.54-0.94) compared to inactivity, and the risk of migraine was also lower among those who consumed alcohol (RR 0.73, 95% CI 0.57-0.94) compared to abstainers. No association was found between smoking, physical activity, alcohol use and risk of TTH.

CONCLUSIONS

The main finding was that current and previous smoking was associated with increased risk of migraine, but not of TTH.

The effects of aerobic exercise for persons with migraine and co-existing tension-type headache and neck pain. A randomized, controlled, clinical trial

Aim To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activities. Pain frequency, intensity, and duration; physical fitness, level of physical activity, well-being and ability to engage in daily activities were assessed at baseline, after treatment and at follow-up. Results Fifty-two persons completed the study. Significant between-group improvements for the exercise group were found for physical fitness, level of physical activity, migraine burden and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Within the exercise group, significant reduction was found for migraine frequency, pain intensity and duration, neck pain intensity, and burden of migraine; an increase in physical fitness and well-being. Conclusions Exercise significantly reduced the burden of migraine and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Exercise also reduced migraine frequency, pain intensity and duration, although this was not significant compared to controls. These results emphasize the importance of regular aerobic exercise for reduction of migraine burden.

Effect of Vitamin D Deficiency on the Frequency of Headaches in Migraine

Background and Purpose

The risk of vitamin D deficiency varies with the season. The frequency of vitamin D deficiency in migraine patients and its association with migraine are unclear.

Methods

We retrospectively evaluated first-visit migraine patients between January 2016 and May 2017, and investigated the demographics, season, migraine subtypes, frequency, severity, and impact of migraine, psychological and sleep variables, climate factors, and vitamin D levels. The nonfasting serum 25-hydroxyvitamin D concentration was measured to determine the vitamin D level, with deficiency of vitamin D defined as a concentration of <20 ng/mL.

Results

In total, 157 patients with migraine aged 37.0±8.6 years (mean±standard deviation) were analyzed. Their serum level of vitamin D was 15.9±7.4 ng/mL. Vitamin D deficiency was present in 77.1% of the patients, and occurred more frequently in spring and winter than in summer and autumn (89.1%, 85.7%, 72.4%, and 61.7%, respectively; p=0.008). In multivariate Poisson regression analysis, monthly headache was 1.203 times (95% confidence interval=1.046–1.383, p=0.009) more frequent in patients with vitamin D deficiency than in those without deficiency after adjusting for demographics, season, migraine subtype, depression, anxiety, and sleep quality. These associations were consistently noted in subgroup analysis of episodic migraine (odds ratio=1.266, p=0.033) and chronic migraine (odds ratio=1.390, p=0.041).

Conclusions

Our study found that a larger number of monthly days with headache was related to vitamin D deficiency among migraineurs. Future studies should attempt to confirm the causal relationship between vitamin D deficiency and migraine.

Pain worsening with physical activity during migraine attacks in women with overweight/obesity: A prospective evaluation of frequency, consistency, and correlates

Background Migraine is a neurological disease involving recurrent attacks of moderate-to-severe and disabling head pain. Worsening of pain with routine physical activity during attacks is a principal migraine symptom; however, the frequency, individual consistency, and correlates of this symptom are unknown. Given the potential of this symptom to undermine participation in daily physical activity, an effective migraine prevention strategy, further research is warranted. This study is the first to prospectively evaluate (a) frequency and individual consistency of physical activity-related pain worsening during migraine attacks, and (b) potential correlates, including other migraine symptoms, anthropometric characteristics, psychological symptoms, and daily physical activity. Methods Participants were women (n = 132) aged 18-50 years with neurologist-confirmed migraine and overweight/obesity seeking weight loss treatment in the Women's Health and Migraine trial. At baseline, participants used a smartphone diary to record migraine attack occurrence, severity, and symptoms for 28 days. Participants also completed questionnaires and 7 days of objective physical activity monitoring before and after diary completion, respectively. Patterning of the effect of physical activity on pain was summarized within-subject by calculating the proportion (%) of attacks in which physical activity worsened, improved, or had no effect on pain. Results Participants reported 5.5 ± 2.8 (mean ± standard deviation) migraine attacks over 28 days. The intraclass correlation (coefficient = 0.71) indicated high consistency in participants' reports of activity-related pain worsening or not. On average, activity worsened pain in 34.8 ± 35.6% of attacks, had no effect on pain in 61.8 ± 34.6% of attacks and improved pain in 3.4 ± 12.7% of attacks. Few participants (9.8%) reported activity-related pain worsening in all attacks. A higher percentage of attacks where physical activity worsened pain demonstrated small-sized correlations with more severe nausea, photophobia, phonophobia, and allodynia (r = 0.18 - 0.22, p < 0.05). Pain worsening due to physical activity was not related to psychological symptoms or total daily physical activity. Conclusions There is large variability in the effect of physical activity on pain during migraine attacks that can be accounted for by individual differences. For a minority of participants, physical activity consistently contributed to pain worsening. More frequent physical activity-related pain worsening was related to greater severity of other migraine symptoms and pain sensitivity, which supports the validity of this diagnostic feature.

Unbalanced plasma TNF-α and IL-12/IL-10 profile in women with migraine is associated with psychological and physiological outcomes

Increased plasma pro-inflammatory and decreased anti-inflammatory cytokines have been implicated in physiological and behavioural aspects of mood- and pain-related disorders, including migraine. In this case-control study, we assessed mood scores, cardiorespiratory fitness (VO_2Peak), and plasma concentrations of TNF-α, IL-1β, IL-6, IL-8, IL-10, and IL-12p70 interictally in women with episodic migraine with/without aura (ICHD-II), taking no preventive medicine, and in healthy women recruited from São Paulo Hospital and local community, respectively. Thirty-seven participants (mean±SD age=34±10 and BMI=26.5±4.9) were assessed. Groups (Control, n=17; Migraine, n=20) showed no differences in age, BMI, and VO_2Peak. Migraine patients showed higher tension (p=0.019) and anxiety scores (p=0.046), TNF-α (p<0.01), and IL-12p70 (p=0.01), while IL-6 (p<0.01), IL-8 (p<0.01), and IL-10 (p<0.01) were decreased compared to control group. Multiple linear regression models showed that migraine was positively associated with TNF-α and IL-12p70, and negatively associated with IL-6, IL-8, and IL-10. Anxiety scores were positively associated with IL-12p70, and VO_2Peak was negatively associated with TNF-α. In conclusion, an exaggeratedly skewed cytokine profile, in particular the TNF-α and 12p70/IL-10 balance may be related to migraine pathomechanisms, and its psychiatric comorbidities and functional capacity. Additional studies are needed to confirm these results.

Provocation of Migraine after Maximal Exercise: A Test-Retest Study

BACKGROUND

Exercise is often recommended in migraine treatment, but strenuous physical activity is also reported as a migraine trigger. The main aim of this study was to evaluate whether migraine can be triggered by a maximal exercise test, using a prospective test-retest method. A secondary aim was to compare the participants who responded to the maximal exercise test with a migraine attack with those who did not suffer a migraine attack after the test.

METHODS

A total of 19 patients reporting exercise as a potential trigger for their migraines were included in the study. After a baseline period of 1 month with measurements of migraine frequency, a cycle ergometer test until exhaustion was used twice on each patient.

RESULTS

A total of 14 patients were test-retested, and of these, 3 reported migraine following both tests, 5 after one of the tests, and 6 did not report migraine after either test. We observed a higher risk of migraine after 1 or 2 tests in patients with a higher baseline migraine frequency (p = 0.036).

CONCLUSION

In conclusion, the study showed that although maximal aerobic exercise can trigger migraine attacks, it does not always provoke an attack even in those who report exercise as a migraine trigger.

Level of physical activity, well-being, stress and self-rated health in persons with migraine and co-existing tension-type headache and neck pain

Background

The prevalence of migraine with co-existing tension-type headache and neck pain is high in the general population. However, there is very little literature on the characteristics of these combined conditions. The aim of this study was to investigate a) the prevalence of migraine with co-existing tension-type headache and neck pain in a clinic-based sample, b) the level of physical activity, psychological well-being, perceived stress and self-rated health in persons with migraine and co-existing tension-type headache and neck pain compared to healthy controls, c) the perceived ability of persons with migraine and co-existing tension-type headache and neck pain to perform physical activity, and d) which among the three conditions (migraine, tension-type headache or neck pain) is rated as the most burdensome condition.

Methods

The study was conducted at a tertiary referral specialised headache centre where questionnaires on physical activity, psychological well-being, perceived stress and self-rated health were completed by 148 persons with migraine and 100 healthy controls matched by sex and average age. Semi-structured interviews were conducted to assess characteristics of migraine, tension-type headache and neck pain.

Results

Out of 148 persons with migraine, 100 (67%) suffered from co-existing tension-type headache and neck pain. Only 11% suffered from migraine only. Persons with migraine and co-existing tension-type headache and neck pain had lower level of physical activity and psychological well-being, higher level of perceived stress and poorer self-rated health compared to healthy controls. They reported reduced ability to perform physical activity owing to migraine (high degree), tension-type headache (moderate degree) and neck pain (low degree). The most burdensome condition was migraine, followed by tension-type headache and neck pain.

Conclusions

Migraine with co-existing tension-type headache and neck pain was highly prevalent in a clinic-based sample. Persons with migraine and co-existing tension-type headache and neck pain may require more individually tailored interventions to increase the level of physical activity, and to improve psychological well-being, perceived stress and self-rated health.

Association between Physical Activity Levels and Physical Symptoms or Illness among University Students in Korea

Background

Low levels of physical activity can cause various physical symptoms or illness. However, few studies on this association have been conducted in young adults. The aim of this study was to investigate the association between physical activity levels and physical symptoms or illness in young adults.

Methods

Subjects were university students who participated in a web-based self-administered questionnaire in a university in Seoul in 2013. We obtained information on physical activities and physical symptoms or illness in the past year. Independent variables were defined as symptoms or illness which were associated with decreased academic performance. Logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) of each physical symptom or illness with adjustment for covariables.

Results

A total of 2,201 participants were included in the study. The main physical symptoms or illness among participants were severe fatigue (64.2%), muscle or joint pain (46.3%), gastrointestinal problems (43.1%), headache or dizziness (38.6%), frequent colds (35.1%), and sleep problems (33.3%). Low physical activity levels were significantly associated with high ORs of physical symptoms or illness. Multivariable-adjusted ORs (95% CIs) in the lowest vs. highest tertile of physical activity were 1.45 (1.14–1.83) for severe fatigue, 1.35 (1.07–1.70) for frequent colds, and 1.29 (1.02–1.63) for headaches or dizziness. We also found that lower levels of physical activity were associated with more physical symptoms or bouts of illness.

Conclusion

Low physical activity levels were significantly associated with various physical symptoms or illness among university students. Also, individuals in the lower levels of physical activity were more likely to experience more physical symptoms or bouts of illness than those in the highest tertile of physical activity.
