Anxiety sensitivity and intentional avoidance of physical activity in women with probable migraine

Isolating unique variance in mental health outcomes attributable to personality variables and childhood emotional abuse

Introduction

University students are at high risk for anxiety and depression. Our main objective was to tease apart variance in symptom severity that was uniquely attributable to four associated variables that are frequently confounded: exposure to childhood emotional abuse, alexithymia, sensory processing sensitivity (SPS), and anxiety sensitivity (AS).

Methods

University students (N = 410) completed an online survey designed to measure our four key study variables along with several other potentially relevant variables including sex, physical activity levels, and perceived COVID-19 impacts.

Results

Over half of the participants reported moderate to extremely severe symptoms of anxiety and depression. Females reported stronger signs of SPS and AS and were more likely than males to have increased their moderate/vigorous exercise since the pandemic began. After controlling for the other variables, the best predictors of perceived COVID-19 impacts were SPS, childhood emotional abuse, and current levels of physical activity. Whereas all three personality variables and childhood emotional abuse emerged as significant predictors of both depression and anxiety, neither COVID-19 impacts nor physical activity levels accounted for unique variance in either model. Unexpectedly, male sex emerged as an additional risk factor for depression, raising the possibility that males experience unique stressors and societal pressures that increase their risk of depression.

Discussion

These findings help to clarify the links between childhood emotional abuse, personality traits implicated in emotional awareness and self-regulation, and mental health. They may have important implications for the development and implementation of individualized treatments for common mental disorders.

Therapeutic Exercise Parameters, Considerations, and Recommendations for Migraine Treatment: An International Delphi Study

OBJECTIVE

The goal of this study was to reach consensus about the best exercise prescription parameters, the most relevant considerations, and other recommendations that could be useful for prescribing exercise to patients with migraine.

METHODS

This was an international study conducted between April 9, 2022 and June 30, 2022. An expert panel of health care and exercise professionals was assembled, and a 3-round Delphi survey was performed. Consensus was reached for each item if an Aiken V Validity Index ≥ 0.7 was obtained.

RESULTS

The study included 14 experts who reached consensus on 42 items by the third round. The most approved prescription parameters were 30 to 60 minutes of exercise per session, 3 days per week of moderate-intensity continuous aerobic exercise, and relaxation and breathing exercises for 5 to 20 minutes every day. When considering an exercise prescription, initial exercise supervision should progress to patient self-regulation; catastrophizing, fear-avoidance beliefs, headache-related disability, anxiety, depression, physical activity baseline level, and self-efficacy could influence the patients' exercise participation and efficacy; and gradual exposure to exercise could help improve these psychological variables and increase exercise efficacy. Yoga and concurrent exercise were also included as recommended interventions.

CONCLUSION

From the experts in the study, exercise prescriptions should be adapted to patients with migraine considering different exercise modalities, such as moderate-intensity aerobic exercise, relaxation, yoga, and concurrent exercise, based on the patients' preferences and psychological considerations, level of physical activity, and possible adverse effects.

IMPACT

The consensus reached by the experts can help prescribe exercise accurately to patients with migraine. Offering various exercise modalities can improve exercise participation in this population. The evaluation of the patients' psychological and physical status can also facilitate the adaptation of the exercise prescription to their abilities and diminish the risk of adverse events.

Effect of genetic liability to migraine and its subtypes on breast cancer: a mendelian randomization study

BACKGROUND

The relationship between migraine and breast cancer risk has generated conflicting findings. We attempted to assess the association between migraine and breast cancer risk using Mendelian randomization (MR) analysis.

METHODS

We selected genetic instruments associated with migraine from a recently published genome-wide association studies (GWAS). Inverse variant weighted (IVW) analysis was adopted as the main method, and we also performed the weighted-median method and the MR‒Egger, MR pleiotropy residual sum and outlier (MR-PRESSO), and MR Robust Adjusted Profile Score (MR-RAPS) methods as supplements.

RESULTS

Our MR suggested that any migraine (AM) was a risk factor for overall breast cancer (IVW: odds ratio (OR) = 1.072, 95% confidence intervals (CI) = 1.035-1.110, P = 8.78 × 10- 5, false discovery rate (FDR) = 7.36 × 10- 4) and estrogen receptor-positive (ER+) breast cancer (IVW: OR = 1.066, 95% CI = 1.023-1.111, P = 0.0024; FDR = 0.0108) but not estrogen receptor-negative (ER-) breast cancer. In its subtype analysis, women with a history of migraine without aura (MO) had an increased risk of ER- breast cancer (IVW: OR = 1.089, 95% CI = 1.019-1.163, P = 0.0118, FDR = 0.0354), and MO was suggestively associated with the risk of overall breast cancer (FDR > 0.05 and IVW P < 0.05). No significant heterogeneity or horizontal pleiotropy was found in the sensitivity analysis.

CONCLUSION

This study suggested that women with AM have an increased risk of overall breast cancer and ER + breast cancer. MO was suggestively associated with the risk of overall breast cancer and ER- breast cancer.

Effects of Exercise Testing and Cardiac Rehabilitation in Patients with Coronary Heart Disease on Fear and Self-Efficacy of Exercise: A Pilot Study

BACKGROUND

Exercise fear and low exercise self-efficacy are common in patients attending cardiac rehabilitation (CR). This study tested whether exercise prescription methods influence exercise fear and exercise self-efficacy. We hypothesized that the use of graded exercise testing (GXT) with a target heart rate range exercise prescription, relative to standard exercise prescription using rating of perceived exertion (RPE), would produce greater reductions in exercise fear and increase self-efficacy during CR.

METHOD

Patients in CR (N = 32) were randomized to an exercise prescription using either RPE or a target heart rate range. Exercise fear and self-efficacy were assessed with questionnaires at three time points: baseline; after the GXT in target heart rate range group; and at session 6 for the RPE group and CR completion. Items were scored on a five-point Likert-type scale with higher mean scores reflecting higher fear of exercise and higher self-efficacy. To analyze mean differences, a mixed effects analysis was run.

RESULTS

There were no significant changes in exercise self-efficacy between baseline and discharge from CR; these were not statistically significant (mean differences baseline - 0.63; end - 0.27 (p = 0.13)). Similarly, there was no change in fear between groups (baseline 0.30; end 0.51 (p = 0.37)).

CONCLUSION

Patients in the RPE and target heart rate groups had non-significant changes in exercise self-efficacy over the course of CR. Contrary to our hypothesis, the use of GXT and target heart rate range did not reduce fear, and we noted sustained or increases in fear of exercise among patients with elevated baseline fear. A more targeted psychological intervention seems warranted to reduce exercise fear and self-efficacy in CR.

Sex-related differences in migraine clinical features by frequency of occurrence: a cross-sectional study

OBJECTIVES

The sex-related differences of migraine hold clinical relevance to achieve a better diagnosis and treatment. The purpose of this cross-sectional study was to evaluate sex-related differences in migraine features, the impact, and health care resources for people who suffer from episodic migraine (EM) and chronic migraine (CM).

METHODS

184 patients (72 % women; 61.4 % with EM; mean (SD) age of 38.7 (10.4) years) were assessed through the Migraine Disability Assessment, the Short Form 36 Health Survey, the Beck Depression Inventory II and the State-Trait Anxiety Inventory. Additionally, medication intake and medical assistance were recorded. Multivariate analyses were performed, stratifying by frequency of occurrence (EM and CM) and sex (men and women).

RESULTS

The results showed that women presented a greater number of symptoms (p=0.03), pain intensity (p<0.01), pain duration (p=0.03), disability (p=0.01), amount of symptomatic medication (p=0.04) and medical visits (p=0.001), as well as a worse physical role (p=0.004) than men with EM. However, no significant differences between them were found for CM (p>0.05). Moreover, it was identified that there was a significant increase in medication intake among people with CM compared to EM (p<0.001). It is worth noting that there were no significant differences by diagnosis and sex in emotional status (p>0.05).

CONCLUSIONS

Migraine features, impact and health care resources were greater in women than men with EM; yet no significant differences between them were found for CM. The findings of the present study may contribute to a better diagnosis and treatment response in people with migraines.

Mechanisms of change in posttraumatic headache-related disability: A mediation model

OBJECTIVE

To explore whether the association between change in headache management self-efficacy and posttraumatic headache-related disability is partially mediated by a change in anxiety symptom severity.

BACKGROUND

Many cognitive-behavioral therapy treatments for headache emphasize stress management, which includes anxiety management strategies; however, little is currently known about mechanisms of change in posttraumatic headache-related disability. Increasing our understanding of mechanisms could lead to improvements in treatments for these debilitating headaches.

METHODS

This study is a secondary analysis of veterans (N = 193) recruited to participate in a randomized clinical trial of cognitive-behavioral therapy, cognitive processing therapy, or treatment as usual for persistent posttraumatic headache. The direct relationship between headache management self-efficacy and headache-related disability, along with partial mediation through change in anxiety symptoms was tested.

RESULTS

The mediated latent change direct, mediated, and total pathways were statistically significant. The path analysis supported a significant direct pathway between headache management self-efficacy and headache-related disability (b = -0.45, p < 0.001; 95% confidence interval [CI: -0.58, -0.33]). The total effect of change of headache management self-efficacy scores on change in Headache Impact Test-6 scores was significant with a moderate-to-strong effect (b = -0.57, p = 0.001; 95% CI [-0.73, -0.41]). There was also an indirect effect through anxiety symptom severity change (b = -0.12, p = 0.003; 95% CI [-0.20, -0.04]).

CONCLUSIONS

In this study, most of the improvements in headache-related disability were related to increased headache management self-efficacy with mediation occurring through change in anxiety. This indicates that headache management self-efficacy is a likely mechanism of change of posttraumatic headache-related disability with decreases in anxiety explaining part of the improvement in headache-related disability.

Migraine in university students: A systematic review and meta-analysis

BACKGROUND

Migraine is a complex, neurobiological disorder usually presenting as a unilateral, moderate to severe headache accompanied by sensory disturbances. Migraine prevalence has risen globally, affecting 14% of individuals and 16% of students and carries many negative impacts in both cohorts. With no recent meta-analysis of global migraine prevalence or associated factors in students, this systematic review and meta-analysis were conducted.

DATABASES AND DATA TREATMENT

The review was registered with PROSPERO (CRD42020167927). Electronic databases (n = 12) were searched for cross-sectional studies (1988 to August 2021, IHS criteria). Ninety-two articles were meta-analysed and 103 were narratively reviewed. The risk of bias was assessed using an established tool.

RESULTS

The risk of bias ranged from low to moderate. Migraine pooled prevalence (R-Studio) was demonstrated at 19% (95% CI, 16%-22%, p < 0.001, I^2 98%): females 23% (95% CI, 19%-27%, p < 0.001), males 12% (95% CI, 9%-15%, p < 0.001). Gender (p < 0.0001), geographical region (p = 0.01), migraine types (p = 0.0002) and prevalence timeframes (p = 0.02) may be influencing the substantial heterogeneity. Migraine triggers were primarily behavioural and environmental and treatments were predominantly pharmaceutical. Impacts ranged from academic performance impairment to psychological co-morbidities.

CONCLUSIONS

This study offers the most comprehensive overview of migraine prevalence and associated factors in university students. Migraine prevalence in university students has increased and has many negative effects. Enhancing migraine recognition and management at university may have positive implications for an improved educational experience, as well as for the burden migraine currently incurs, both in university and beyond.

SIGNIFICANCE

This global systematic review and meta-analysis of 92 studies and narrative review of 103 studies provide the most comprehensive synthesis to date of migraine prevalence and associated factors in university students. Pooled prevalence has increased to 19%. The significant heterogeneity demonstrated is influenced by gender, geographical region, migraine type and prevalence timeframes. Students manage migraines primarily with pharmaceuticals. Further studies conducted in low and middle-income countries, following headache protocols and reporting frequency of treatment-seeking and medication usage are warranted.

Behavioral Management of Episodic Migraine: Maintaining a Healthy Consistent Lifestyle

PURPOSE OF REVIEW

To describe the most recent findings related to lifestyle behaviors and migraine.

RECENT FINDINGS

An individualized conceptualization of how lifestyle factors impact migraine activity has increased our understanding of the role of behavioral interventions for episodic migraine. Healthy diets of several types have been associated with migraine attack reduction, whereas disruptions in diet like skipping meals are associated with migraine attack onset. Both aerobic activity and lower intensity yoga interventions show promise for migraine prevention. Sleep disruption has been associated with migraine day and may have a bi-directional relationship. Both increases and decreases in stress have been associated with migraine activity. Evidence is converging around the principle that highly unusual disruptions in daily routine are particularly associated with migraine attack onset and that a consistent healthy lifestyle is a key feature of effective behavioral migraine prevention strategies.

The importance of an early onset of migraine preventive disease control: A roundtable discussion

Background:

Newly approved migraine preventive therapies have allowed for rapid control of migraine activity, offering potential to minimize the burden of migraine. This report summarizes a roundtable discussion convened to analyze evidence for early onset of prevention, ascertain its clinical relevance, and provide guidance for healthcare professionals in crafting goals and treatment expectations for patients with migraine initiating preventive therapy.

Methods:

A virtual roundtable meeting of migraine clinicians, researchers, and patient advocates convened in October 2020. Participants reviewed and discussed data summarizing patient and healthcare professional perceptions of migraine prevention and evidence from the peer-reviewed and gray literature to develop corresponding recommendations.

Summary:

Evidence from clinical studies of anti-calcitonin gene-related peptide monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) and the chemodenervation agent onabotulinumtoxinA indicate that patients may experience reduction of migraine activity within 7 days of drug administration and early attainment of disease control is associated with improvements in clinically important outcomes. The roundtable of experts proposes that early onset be defined as demonstration of preventive benefits within 1 week of treatment initiation. We recommend focusing discussion with patients around “disease control” and potential benefits of early onset of prevention, so patients can set realistic preventive therapy goals and expectations.

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.

Fear, Avoidance, and Disability in Headache Disorders

PURPOSE OF REVIEW

The purpose of this review is to summarize the role of avoidance behavior in headache-related disability and overview relevant clinical implications.

RECENT FINDINGS

Avoidance occupies a central role in contemporary psychological perspectives on headache disorders and other chronic pain conditions. Several cognitive constructs of relevance to headache are influenced and maintained by avoidance behavior. A growing body of literature attests to the notion that avoidance of headache triggers, of stimuli that exacerbate headache, and of broader life domains can negatively affect headache progression, disability/quality of life, and comorbid psychiatric symptoms. Interventions targeting avoidance behavior, such as therapeutic exposure to headache triggers, mindfulness, and acceptance and commitment therapy (ACT), hold promise for headache disorders but need to be tested in larger trials. Researchers and clinicians are encouraged to attend to functional impairment as a critically important treatment outcome. Comprehensive understanding of headache disorders necessitates attention not merely to diagnostic symptoms and their reduction, but to patterns of avoidance behavior that inadvertently exacerbate headache and contribute to functional impairment.

Psychometric Properties of the Chinese Version of Anxiety Sensitivity Index-3 in Women Diagnosed With Breast Cancer

Background

Anxiety sensitivity (AS) is a trait-like predisposing factor for the prevalence of anxiety in patients diagnosed with breast cancer. The Anxiety Sensitivity Index-3 (ASI-3) has been widely used in both general and clinical samples for measuring AS. However, the data about its psychometric properties in women with breast cancer are deficient. In addition, there is no evidence proving the measure equivalence of ASI-3 across sociodemographic variables in the specific sample. Thus, the present study examined the psychometric properties and conducted measure equivalence testing of ASI-3 in Chinese women diagnosed with breast cancer.

Methods

This study included 815 Chinese women diagnosed with breast cancer. Single group confirmatory factor analysis (CFA) was administrated to detect the factorial validity of ASI-3, and multigroup CFAs were conducted to test the measurement equivalence of ASI-3 across various sociodemographic variables. The reliability of ASI-3 was tested by Cronbach's alpha coefficient, Guttman split-half coefficient, McDonald's omega coefficient, and test-retest coefficient. The standardized factor loadings, construct reliability, and the average variance extracted of factors were used to measure the construct validity of ASI-3, and the partial correlations were conducted to examine the criterion-related validity of ASI-3.

Results

The ASI-3 had satisfactory reliability and validity in Chinese women diagnosed with breast cancer; three-factor model fitted the data well in CFA and reached partial strict invariances across age, education, and residence groups.

Conclusion

This study explored the psychometric properties and measurement invariance across sociodemographic variables of ASI-3 in Chinese women diagnosed with breast cancer. Our results not only proved that the ASI-3 is an appropriate instrument for measuring AS but also deepened the understanding of ASI-3 in Chinese women with malignancy.
