Background: A close association has been reported between depression and migraine. However, information concerning the impacts of migraine on the clinical presentation and prevalence of depression in a population-based study is currently limited., Methods: Data from the Korean Headache-Sleep Study, a nationwide survey about headache and sleep for adults aged 19-69 years were used. Depression was defined when Patient Health Questionnaire-9 score ≥ 10., Results: Of 2,695 participants who included in this study, 116 (4.3%), 143 (5.3%), and 1130 (41.9%) had depression, migraine, and non-migraine headache, respectively. Migraine (24/116 [20.5%] vs. 119/2579 [4.7%], p < 0.001) and non-migraine headache (67/116 [58.1%] vs. 1063/2579 [41.3%], p < 0.001) was more prevalent in the group of participants with depression than among participants without depression. Among participants with depression, there was no statistically differences in total Patient Health Questionnaire-9 (PHQ-9) scores among migraine, non-migraine headache, and non-headache groups (median with interquartile range, 12.0 [10.2-18.0] vs. 13.0 [11.0-16.0] vs. 12.0 [10.0-15.2], p = 0.514). Among subcomponent scores of PHQ-9, all subcomponent scores did not significantly differ by headache status except feeling tired or having little energy scores (non-migraine headache 2.0 [2.0-3.0] vs. non-headache 2.0 [1.0-2.0], p = 0.010)., Limitations: Diagnosis of depression based on PHQ-9 questionnaire and small sample size in subgroup analyses., Conclusions: Participants with depression exhibit an increased risk of migraine and non-migraine headache compared with participants without depression. Among participants with depression, the severity of depression did not significantly differ on the basis of headache status., Competing Interests: Conflict of Interest Statement Dong Hyun Lee: None.

Anxiety, depression, and insomnia are highly prevalent among migraineurs and are associated with negative health consequences. Anxiety and depression, however, unlike insomnia, are usually underdiagnosed, due to less self-reporting of these two conditions. The aim of the present study was to evaluate the risk of anxiety and depression in migraineurs with self-reported insomnia, using a general population-based sample. We used data from a nationwide population-based survey on headache and sleep, the Korean Headache-Sleep Study. Of all 2,695 participants, 143 (5.3%), 268 (10.0%), 116 (4.3%), and 290 (10.8%) were classified as having migraine, anxiety, depression, and self-reported insomnia, respectively. The risk of anxiety (odds ratio [OR] = 7.0, 95% confidence interval [CI] = 3.0-16.7) and depression (OR = 3.3, 95% CI = 1.3-8.5) was significantly increased in migraineurs with self-reported insomnia. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for anxiety in migraineurs with self-reported insomnia were 46.5%, 89.0%, 64.5%, and 79.5%, respectively. For depression, the sensitivity, specificity, PPV, and NPV were 41.7%, 82.4%, 32.3%, and 87.5%, respectively. Self-reported insomnia is likely to be comorbid with anxiety and depression in migraineurs and could thus be a useful predictor of anxiety and depression in migraine.

Objective: This study was conducted to investigate sex differences in the prevalence and clinical presentation of migraine and probable migraine in a general population-based sample., Background: While there is research on sex differences in clinical characteristics and their impact on migraine headache, only few studies have investigated sex differences in probable migraine in population-based settings. Moreover, compared with Western countries, the prevalence of probable migraine in Asia is relatively high. This cross-sectional study was designed to investigate sex differences in the prevalence and clinical presentation of migraine and probable migraine in a general population-based sample., Methods: We used the data of the Korean Headache-Sleep Study, which is a nationwide survey on headache and sleep., Results: We interviewed 7430 people, and 3114 of them agreed to participate in our study (rejection rate, 58.1%). Among these people, 419 withdrew their participation during the interview. Ultimately, 2695 people completed our survey (cooperation rate, 36.3%). The prevalence of overall migraine and probable migraine was 350/1350 (25.9%) for women and 172/1345 (12.8%) for men (P < .001, respectively). The prevalence of migraine (107/1350 [7.9%] vs 36/1345 [2.7%], P < .001) and probable migraine (243/1350 [18.0%] vs 136/1345 [10.1%], P < .001) was significantly higher among women than among men. Headache frequency per month (median [interquartile range]) (1.0 [0.3-3.0] vs 0.8 [0.3-2.0], P = .037), the visual analog scale score for headache intensity (5.0 [4.0-7.0] vs 5.0 [3.0-6.0], P = .019), and the impact of headache {Headache Impact Test-6 score (47.0 [42.0-54.0] vs 44.0 [42.0-51.8], P = .013)} were significantly higher among women with probable migraine than men. Headache frequency per month (2.0 [0.4-4.0] vs 1.0 [0.3-2.0], P = .073), headache intensity (6.0 [5.0-8.0] vs 6.0 [4.2-7.0], P = .281), and the impact of headache (55.0 [48.0-61.0] vs 49.0 [46.3-60.8], P = .225) were not significantly different between women and men with migraine. Other comorbidities or associated symptoms, such as anxiety and depression, were not significantly different between women and men with migraine and probable migraine, except for nausea in probable migraine., Conclusion: Women experience more severe symptoms and a higher impact of headache than men among participants with probable migraine. Our findings suggest that women with PM need a more intensive evaluation and treatment than men with PM., (© 2019 American Headache Society.)

Background Although probable migraine (PM) is common among headache sufferers, there is little knowledge of the prevalence and impacts of comorbid anxiety and depression in patients with PM. We assessed the prevalence and impact of anxiety and depression among PM sufferers in the general population. Methods We recruited Korean individuals aged 19-69 years via stratified random sampling and assessed headache type, anxiety, and depression among them using structured interviews. Results In a representative sample of 2695 individuals, 143 (5.3%) and 379 (14.1%) had migraine and PM, respectively. Fewer patients with PM had anxiety (17.7% vs. 30.1%, p = 0.002) and depression (8.7% vs. 16.8%, p = 0.007) compared to those with migraine. Prevalence of anxiety and depression was lower in people with PM than in those with migraine in univariable analysis, but insignificant after including headache intensity and headache frequency for adjustment. Headache frequency, headache intensity, and impact of headache were significantly higher among PM and migraine patients with anxiety and depression than among those without. Conclusions The prevalence of anxiety and depression was lower among individuals with PM compared to those with migraine. However, they were still prevalent and associated with an exacerbation of symptoms among individuals with PM.

Background: Insomnia is a common complaint among individuals with migraine. The close association between insomnia and migraine has been reported in clinic-based and population-based studies. Probable migraine (PM) is a migrainous headache which fulfills all but one criterion in the migraine diagnostic criteria. However, an association between insomnia and PM has rarely been reported. This study is to investigate the association between insomnia and PM in comparison with migraine using data from the Korean Headache-Sleep Study., Methods: The Korean Headache-Sleep Study is a nation-wide cross-sectional survey for all Korean adults aged 19-69 years. The survey was performed via face-to-face interview using a questionnaire on sleep and headache. If an individual's Insomnia Severity Index score was ≥15.5, she/he was diagnosed as having insomnia., Results: Of 2695 participants, the prevalence of migraine, PM and insomnia was 5.3, 14.1 and 3.6 %, respectively. The prevalence of insomnia among subjects with PM was not significantly different compared to those with migraine (8.2 % vs. 9.1 %, p = 0.860). However, insomnia prevalence in subjects with PM was significantly higher than in non-headache controls (8.2 % vs. 1.8 %, p < 0.001). Insomnia Severity Index score was significantly higher in subjects with migraine compared to those with PM (6.8 ± 5.8 vs. 5.5 ± 5.8, p = 0.012). Headache frequency and Headache Impact Test-6 score were significantly higher in subjects with migraine and PM with insomnia compared to those without insomnia. Multivariable linear analyses showed that anxiety, depression, headache frequency and headache intensity were independent variables for contributing the ISI score among subjects with PM., Conclusions: The prevalence of insomnia among subjects with PM was not significantly different compared to those with migraine. Anxiety, depression, headache frequency and headache intensity were related with ISI score in subjects with PM.

Although tension-type headache (TTH) is a frequent type of headache disorder and imposes a significant burden, there is scant information about the prevalence and impact of comorbid anxiety and depression among individuals with TTH. We investigated the prevalence and clinical impact of anxiety and depression among patients with TTH in the general population. We recruited Korean participants aged 19-69 years using a two-stage clustered random sampling method. To identify the presence of headache type, anxiety, and depression, we used a semi-structured interview using certain questionnaires. To assess the level of anxiety and depression, we used the Goldberg Anxiety Scale and Patient Health Questionnaire-9, respectively. Among 2,695 participants, 570 people (21.2%) had TTH during previous 1 year. In participants with TTH, the prevalence of anxiety (9.5% vs. 5.3%, p = 0.001) and depression (4.2% vs. 1.8%, p = 0.001) was significantly higher than that of non-headache participants. The prevalence of anxiety among TTH participants with >15 attacks per month [21.4%, odds ratio (OR): 4.0] and 1-14 attacks per month (13.1%, OR: 2.2) was higher than that in those with <1 attack per month (6.4%), however this tendency was not observed in participants with depression. Visual Analogue Scale (VAS) score [median 5.0 vs. 4.0, p = 0.010] and Headache Impact Test-6 (HIT-6) score [median 45.5 vs. 42.0, p < 0.001] were significantly higher among those with anxiety. Furthermore, VAS scores [median 5.0 vs. 4.0, p = 0.010] and HIT-6 scores [median 45.5 vs. 42.0, p = 0.027] were also significantly higher among TTH patients with depression than among those without depression. In conclusion, anxiety and depression were more prevalent in participants with TTH than in non-headache participants. These two conditions were associated with an exacerbation of headache symptoms in individuals with TTH., Competing Interests: The authors have declared that no competing interests exist.

Objective: Insomnia and depression are prevalent disorders that often co-occur. This study aimed to investigate the impact of clinically significant insomnia symptoms on the prevalence and clinical presentation of clinically significant depressive symptoms and vice versa. Methods: This study used data from the Korean Headache-Sleep Study (KHSS), a nationwide cross-sectional population-based survey regarding headache and sleep. Clinically significant insomnia symptoms were defined as Insomnia Severity Index (ISI) scores ≥ 10 and clinically significant depressive symptoms were defined as Patient Health Questionnaire-9 (PHQ-9) scores ≥ 10, respectively. We referred clinically significant insomnia symptoms and clinically significant depressive symptoms as insomnia symptoms and depressive symptoms, respectively. Results: Of 2,695 participants, 290 (10.8%) and 116 (4.3%) were classified as having insomnia and depressive symptoms, respectively. The prevalence of depressive symptoms was higher among participants with insomnia symptoms than in those without insomnia symptoms (25.9 vs. 1.7%, respectively, P < 0.001). Among participants with depressive symptoms, the PHQ-9 scores were not significantly different between participants with and without insomnia symptoms (P = 0.124). The prevalence of insomnia symptoms was significantly higher among participants with depressive symptoms than in those without depressive symptoms (64.7 vs. 8.3%, respectively, P < 0.001). The ISI scores were significantly higher among participants with insomnia and depressive symptoms than in participants with insomnia symptoms alone (P < 0.001). Conclusions: Participants with depressive symptoms had a higher risk of insomnia symptoms than did those without depressive symptoms. The severity of depressive symptoms did not significantly differ based on insomnia symptoms among participants with depressive symptoms; however, the severity of insomnia symptoms was significantly higher in participants with depressive symptoms than in those without depressive symptoms.

Objective: The aim of this study was to evaluate sleep characteristics associated with drowsy driving in an adult population.Methods: The study subjects consisted of 1675 adults aged 19 years or older who completed a population-based questionnaire survey on sleep habits. Experiences of drowsy driving were obtained from self-reported data. We investigated sleep-related variables including sleep duration, sleep efficiency, chronotype, subjective sleep perception, daytime sleepiness, sleep quality, and snoring. We performed multivariate logistic regression analysis to determine sleep characteristics independently associated with drowsy driving.Results: The mean age of the subjects was 43.2 years, and 66.3% were men. The prevalence of self-reported drowsy driving was 23.6% (396 of 1675), and 33.1% of subjects experienced dozing at the wheel at least once a month. Multivariate analysis demonstrated that men, office and manual workers, excessive daytime sleepiness, depression, habitual snoring, and perceived insufficient sleep were independently associated with drowsy driving. Subgroup analyses revealed that reduced weekday sleep duration was a risk factor of drowsy driving in adults with perceived sufficient sleep. On the other hand, frequent alcohol drinking significantly increased risk of drowsy driving in the subgroup with perceived sleep insufficiency. Furthermore, ordinal regression analyses confirmed the association between sleep characteristics and drowsy driving across different drowsy driving frequencies.Conclusion: Excessive daytime sleepiness, depression, habitual snoring, and perceived insufficient sleep were sleep-related risk factors for drowsy driving. In addition to maintaining healthy sleep habits, individuals at high risk should be encouraged to evaluate underlying sleep disorders or psychiatric problems to prevent drowsy driving.
