Recurrent headache in adolescents: nonreferred versus clinic population

OBJECTIVE: To compare headache activity, psychosocial measures, and cold pressor response between referred and nonreferred adolescents with frequent headache. DESIGN: Thirteen boys and 19 girls with a mean age of 13.4 +/- 0.9 years who had been referred to a hospital-based behavioral treatment program for recurrent headache were compared with an age- and sex-matched school-based population of nonreferred students consisting of 31 adolescents with frequent headaches and 32 adolescents with infrequent or no headaches. All subjects completed the Spielberger State-Trait Anxiety Inventory/Trait form, the Children's Depression Inventory, the Childhood Somatization Inventory, and measures of headache activity and related functional disability. Additionally, all subjects reported interval discomfort scores on a 40-second cold pressor test with arm immersion in a 10 degrees +/- 1 degree C cold water bath. RESULTS: Subjects from both headache groups reported significantly more anxiety than those with infrequent or no headaches. The school-based nonreferred adolescents reported more depressive symptoms than the clinic-based referred subjects. In addition, the latter group reported headaches of longer duration and more school days missed due to headaches than both other groups. Whereas school-based subjects and those with infrequent or no headaches reported relatively low initial cold pressor test scores and gradually reported increasing scores with time, clinic-based subjects rated their discomfort as high at the initial interval report and maintained high levels throughout the test. No differences in somatization were found among groups. CONCLUSION: Although adolescents who seek behavioral treatment for recurrent headache do not report more psychological symptoms than nonreferred adolescents with frequent headaches, they report headaches of longer duration, miss more school days due to headache, and report higher initial sustained discomfort scores to a standardized noxious stimulus.     

Emotional/behavioural, social correlates and one-year predictors of frequent pains among early adolescents: influences of pain characteristics.

In a one-year longitudinal study, emotional/behavioural correlates and predictors of four common pain complaints (headaches, stomach, back and limb pain), were examined in a representative school sample of 2360 adolescents aged 12- to 15-years. At first assessment, 18.3% reported being bothered by a frequent pain (at least once a week) and 40% of the pain sufferers had two or more pain locations, more commonly reported by girls. Subjects having any of the four frequent pains reported having fewer friends and were more often absent from school. Frequency and number of reported pains among adolescents were positively related to levels of internalising and externalising problems. These latter problems were consistently and significantly higher among adolescents with frequent back and limb pains, however, when coexistence of another frequent pain was controlled, differences were small. Number of pains at the one-year follow-up was significantly predicted by frequent back pain and headache, depressive symptoms scores, somatic complaints (other than pain), number of friends and reduced leisure time activities during the follow-up period. Frequent back pain and depressive symptoms also predicted multiple frequent pains (vs single frequent pain) at the follow-up as did recent parental divorce. It is concluded that various emotional and behavioural problems, and which are commonly regarded as being specifically related to pain type or location among adolescents, depend rather on frequency and coexistence of multiple frequent pains. Assessment of adolescents with frequent and multiple pains should, therefore, include broad screening of internalising as well as externalising problems as well as various aspects of impairment.     

One-year incidence, course, and outcome predictors of frequent headaches among early adolescents

OBJECTIVE: To examine the prevalence rate, course, annual incidence, and predictors of frequent headaches (at least once a week) in a 1-year longitudinal study of a representative school sample of 2355 adolescents aged 12 to 14 years. METHODS: Information was gathered by means of questionnaires administered to the subjects at school. RESULTS: The overall prevalence estimates of frequent headaches, including those subjects reporting another type of frequent pain, were 8.1% and 8.9% at the two assessment points (T(1) and T(2)), and 3.3% to 4% for frequent headaches without other frequent pain complaints. Both forms of frequent headaches were about three times more common among girls than boys. Persistence of frequent headaches (with possible pain comorbidity) was high, in that more than one-third of adolescents reporting frequent headaches continued to have such headaches 1 year later. Persistence also increased with age, in particular among 13- to 14-year-old girls. The overall annual incidence of frequent headaches in the whole sample was 6.5%. While incidence was about twice as high among adolescent girls than boys, there was a steady increase among girls, whereas the rates were stable in boys. The results of multivariate regression analyses showed that frequent headaches at 1-year follow-up could be significantly predicted by frequent headaches at first assessment, impairment (reduced leisure time activities), and high depressive symptom scores, in addition to gender (girls had a worse outcome). CONCLUSIONS: Frequent headaches, among girls in early adolescence in particular, should be carefully evaluated, and treatment offered to those who are impaired in their daily life functioning.     

Kopf‑, Bauch- und Rückenschmerzen bei Kindern und Jugendlichen in Thüringen

Recurring pain in children and adolescents can have a negative impact on health and well-being. This study investigates recurring headache, abdominal pain, and back pain in children and adolescents in Thuringia. Data is based on a representative sub-sample from the federal state module Thuringia (2010–2012, n?=?4096, 3–17 years), carried out in KiGGS wave 1 (first follow-up interview of the “German Health Interview and Examination Survey for Children and Adolescents”). The 3?month prevalence of recurrent headache, abdominal pain, and back pain is reported according to socio-demographic factors and is compared with the prevalence for the whole of Germany. In addition, possible associated factors of recurring headache, abdominal pain, and back pain in the previous 3 months are analyzed. Results for Thuringia show that 3? to 10-year-old children were most frequently affected by recurrent abdominal pain (girls: 24.1%; boys: 16.7%), while 11- to 17-year-old adolescents were most frequently affected by recurrent headaches (girls: 36.8%; boys: 20.6%). There were isolated socio-economic differences in the 3?month prevalences of recurrent headache and back pain to the detriment of the low status group. Compared to peers in the whole of Germany, girls and boys in Thuringia did not report headache, abdominal pain, and back pain in the previous 3 months more frequently. The investigated associated factors—fair to very poor self-rated health, emotional problems such as anxiety and depressive symptoms, chronic diseases and other health complaints, migraine, use of a general medical practice, as well as practices for orthopedics and neurology, and in-patient treatment at a hospital—were positively related to the 3?month prevalence of recurrent headache, abdominal pain, and back pain. Overall, the results confirm that recurring pain is a common phenomenon in childhood and adolescents and, therefore, underline the public health relevance of pain in this young age group.     

The prevalence of migraine and tension-type headaches among adolescents in Norway. The Nord-Trøndelag Health Study (Head-HUNT-Youth), a large population-based epidemiological study

The aim of this study was to examine the prevalence of headache and primary headache disorders like migraine and tension-type headaches among adolescents, and to explore the differences in headache prevalence and frequency by gender and age. This cross-sectional study was conducted in Nord-Tr?ndelag county, Norway, during the years 1995-97. In total, 8984 (88%) out of 10 202 invited adolescents aged 12-19 years participated in the youth part of the Nord-Tr?ndelag Health Study [Helseunders?kelsen i Nord-Tr?ndelag (HUNT)]. The total study population in this study consisted of 8255 individuals after exclusion of invalid questionnaires and students outside the target range of 13-18 years of age. The students completed a comprehensive questionnaire, and one of the questions was whether the students had experienced any headaches during the last 12 months. In addition, 5847 of these students were also subject to an interview in which they were asked whether they had experienced recurring headaches during the last year and, if so, were they classified as migraine (MI), tension-type headache (TTH) or non-classifiable headache. In the total questionnaire-based population, 76.8% reported having had headaches during the last 12 months (69.4% boys and 84.2% girls). Among those who also were interviewed, 29.1% reported having recurrent headaches (21.0% boys and 36.5% girls). The overall 1-year prevalence of migraine was 7%, of tension-type headache 18%, and of non-classifiable headache 4.8%. Higher prevalence rates were found for girls in all age groups and for all headache categories. The overall frequency of recurrent headaches did not vary significantly with age, but girls had significantly more frequent headaches than boys. We concluded that headache in general, and recurrent primary headache disorders like migraine and tension-type headaches, are common somatic complaints among Norwegian adolescents, especially among girls.     

Patient-centered outcomes for frequent headaches

OBJECTIVE: To identify clinical outcomes that headache sufferers consider meaningful. BACKGROUND: Several standardized instruments have been developed to assess the severity of headaches and the impact of headaches on an individual's quality of life. To our knowledge, however, little research has been conducted to determine which of these many clinical endpoints are considered by headache sufferers themselves to be most important. METHODS: We conducted 4 focus groups with patients with frequent headaches who had recently participated in a randomized clinical trial. Subjects were informed that the purpose of the focus groups was to help healthcare providers learn how to better recognize if their patients' headache conditions improved or worsened over time. RESULTS: Five salient topics emerged from the discussions: (1) severity of pain associated with headaches; (2) definition of meaningful symptom relief; (3) uncertainty regarding timing and severity of headaches; (4) devaluation of the impact of headaches on sufferers; and (5) assessments of pain. Participants stated unambiguously that headache pain is one of the most important aspects of their headache experience. Each of the 4 groups agreed that an increase in the number of pain-free days would be meaningful. Participants also reported that daily headache diaries are not overly burdensome to complete and that the diaries helped them identify useful trends over time. CONCLUSIONS: Our findings suggest that severity and frequency of headache pain are important clinical outcomes from patients' perspective, and that headache diaries are a feasible and useful method of assessing meaningful clinical change over time. Although standardized questionnaires that assess functional status, disability, or health-related quality of life may help quantify patients' response to treatment for frequent headaches, participants in this study did not consider such questionnaires particularly informative. Further research is needed to validate headache diaries among patients with headache in the primary care setting.     

Age-dependent relationships among pain, depressive symptoms, and functional disability in youth with recurrent headaches

OBJECTIVE: To assess age differences associated with depressive symptoms and functional disability in children and adolescents with recurrent headache. BACKGROUND: Research has indicated that psychological factors, especially depression, are related to the extent and nature of functional disability experienced from headaches. There is a lack of research examining how age impacts the relationship between pain, psychological factors, and activity restriction in children and adolescents with recurrent headache. METHODS: Seventy-seven participants from a pediatric neurology clinic completed self-report measures of pain intensity, depressive symptoms, and functional disability. RESULTS: Findings demonstrated a significant positive correlation between pain and functional disability, and depressive symptoms and functional disability for children. Correlations for adolescents failed to reach significance. Functional disability emerged as a mediator between headache pain and depressive symptoms for children but not for adolescents. CONCLUSIONS: Results indicate potentially important age differences when examining the impact of functional disability on depressive symptoms in this sample. Findings suggest that functional disability may contribute to depressive symptoms differently for children versus adolescents with recurrent headache. Age-specific interventions that differentially focus on the specific roles that pain, depressive symptoms, and disability have for children and adolescents with recurrent headache may be warranted.     

Psychosocial,mechanical, and metabolic factors in adolescents’ musculoskeletal pain in multiple locations: A cross‐sectional study

Recent studies indicate that adolescents often experience musculoskeletal pains in two or more body locations. However, previous studies have mainly focused on localized pains, and the determinants of multiple musculoskeletal pains in adolescents are not well known. The present study was set to evaluate the role of psychosocial, mechanical, and metabolic factors in adolescents’ musculoskeletal pains in multiple locations. The study population consisted of the 1986 Northern Finland Birth Cohort; 15‐ to 16‐year‐old adolescents (n=6986), who responded to a mailed questionnaire in 2001. We assessed the associations of emotional and behavioral problems, physical activity, sitting time, sleeping time, overweight and smoking with musculoskeletal pains using multinomial logistic regression. Multiple pains were common, 23% of boys and 40% of girls reported feeling pain in at least three locations over the past 6 months. These pains were not only associated with anxious/depressed symptoms, withdrawn/depressed symptoms, somatic complaints, rule‐breaking and aggressive behavior, social problems, thought and attention problems, but also with high physical activity level, long sitting time, short sleeping time and smoking, among both boys and girls. In addition, pain in three to four locations associated with overweight in girls. A high number of psychosocial, mechanical and metabolic factors associated strongly with multiple pains. In conclusion, multiple musculoskeletal pains were strongly associated with psychosocial complaints, but also with mechanical and metabolic factors. Reported musculoskeletal pains in multiple locations in adolescence may have both peripheral (trauma, decreased regenerative ability) and central (sensitivity) causes.     

Headache and dysfunction of the masticatory system in adolescents

An epidemiologic group of 285 17-year-old adolescents was studied with the aid of a questionnaire for frequency and intensity of headache and for symptoms of dysfunction of the masticatory system. They were also subjected to a functional examination of the masticatory system. Recurrent headaches occurred significantly more often among the girls (18%) than the boys (6%). Girls also reported significantly more intense headaches than boys. Fatigue in the jaws and difficulties in chewing were commoner in those with frequent and more intensive headaches. Tenderness to palpation of the masticatory muscles and impaired mandibular mobility were significantly commoner findings among those with recurrent headaches and those with more intense headaches. Tooth-grinding and clenching were related to frequency but not to intensity of headache. The investigation showed a significant relationship between frequency and intensity of headaches and signs and symptoms of dysfunction of the masticatory system.     

Disability is the major determinant of the severity of depressive symptoms in primary headaches but not in low back pain

Pain syndromes are often associated with depression. In a prospective study we analysed if determinants of depression differ among patients with different primary headaches and between headaches and non-headache pain. During a 2-year period between 1 February 2002 and 31 January 2004, 635 subjects (migraine n = 231; tension-type headache n = 176; cluster headache n = 11; patients with low back pain n = 103; and healthy subjects n = 114) seen by two neurologists filled in a questionnaire on pain characteristics, the MIDAS questionnaire and the Beck Depression Inventory. A multivariate general regression model was used to identify independent predictors of the severity of depressive symptoms. Pain was most frequent in chronic tension-type headache and most intense in the cluster subgroup (P < 0.001, Kruskal-Wallis ANOVA). In univariate tests gender, age, pain frequency, pain intensity and disability were all significantly associated with the severity of depressive symptoms. In the multivariate model disability was the most important independent determinant of the severity of depressive symptoms in the pooled headache group as well as in the migraine and tension-type headache subgroups. In contrast to patients with headache, pain frequency and pain intensity were the significant independent predictors of the severity of depressive symptoms in patients with low back pain. In a multivariate model, after controlling for other factors, determinants of the severity of depressive symptoms were different in headache and non-headache pain subjects, suggesting a different mechanism for developing depression in primary headaches and in other pain syndromes.     

Prevalence and predictors of headaches in US adolescents

OBJECTIVES: To examine the prevalence of headaches among US adolescents; to explore the differences in prevalence by sex, race, and age; and to test the nature of the association between headaches and depression, self-esteem, and insomnia. METHODS: This longitudinal study used a nationally representative sample of adolescents (n = 6072) who were interviewed in 1995 (wave 1) and then interviewed a year later in 1996 (wave 2). Path analyses were used to test for the relationships among headaches, insomnia, depression, and self-esteem. RESULTS: More than 90% of subjects had experienced one or more headaches during the past 12 months. Of that 90%, about 30% reported recurrent headaches occurring weekly or more frequently. Girls tended to report more recurrent headaches (37.6%) than boys (21.3%). American Indians experienced the highest rate (35. 6%) of recurrent headaches followed by white adolescents (32.1%). Depression and low self-esteem in wave 1 were found to precede the headaches in wave 2 in girls, but not in boys. No causal relationship was found between insomnia and headaches. CONCLUSIONS: Headaches are prevalent among US adolescents, especially in girls and American Indians. This study suggests the existence of different paths involving different factors in headache-presenting behavior for boys and girls. Further studies are needed to illustrate the different mechanisms of headache in the two sexes.     

Prevalence and Burden of Headache and Migraine in Germany

Objective.— To determine prevalence and burden of headache and migraine in the general population in Germany including patterns of healthcare and medication use.
Methods.— Telephone interviews were conducted on a representative sample of the general population in Germany aged ≥18 years (n = 7341). Migraine was diagnosed according to the International Headache Society criteria.
Results.— One-year prevalence was: headache 60.2%, migraine 10.6%, nonmigrainous severe headache 24.7% (women 66.6%, 15.6%, and 27.1%; men 53.0%, 5.3%, and 22.2%). Approximately 60% of headache sufferers reported severe headaches, 30% of which were migrainous. Migraineurs reported more often frequent headaches, disability, use of analgesics, and medical consultation than individuals with nonmigrainous severe headaches. Only 42% of migraineurs had consulted a physician and the majority relied exclusively on over-the-counter medication.
Conclusion.— Migraine accounts for a great part of the healthcare impact of headaches in Germany. However, the majority of migraineurs do not seek medical care and may not be optimally treated.     

An Epidemiological Study of Headaches Among Medical Students in Athens

In order to study the prevalence of frequent headaches among the medical students of Athens University, an epidemiological survey was carried out among 588 medical students (318 men and 270 women), with mean age 23.5 years. Two questionnaires were designed for the study: one general, consisting of 10 questions and a second one, specific for headache sufferers, consisting of 117 questions. All those with headache who voluntarily completed the two questionnaires also underwent a neurological examination. Thirty point eight percent of men and 50.3% of women reported various headache attacks during the previous 6 months (39.6% in both sexes). However, only the 11.9% of students (from both sexes) reported that they suffered from disturbing headaches. The 6-month prevalence of migraine was 2.4% and 9.5% for tension-type headache (in both sexes). Cluster headache was not traced. The prevalence of nonclassifiable headaches (according to the criteria of the International Headache Society) was 0.85%. Headache was correlated to sex (more frequent among women) and anxiety level (Hamilton scale for anxiety). Headache prevalence was not correlated to smoking and social class.     

Quality of life in adolescents with chronic pain in the head or at other locations

The differences in quality of life and school absence were studied in one hundred adolescents from the open population who had reported chronic headache or chronic, physically unexplained, pain at other locations. The adolescents kept a 3-week diary about their pain and completed a quality of life questionnaire. Of all chronic pain sufferers in this study, it was the adolescents with headache who showed the least frequent pain, but they reported the poorest quality of life and the largest school absence due to their pain. Adolescents with headache or adolescents with back pain showed the highest negative correlations between pain parameters and quality of life. Headache sufferers showed highly negative relationships between pain parameters and most quality of life domains (median r = -0.46), and only in headache sufferers did this involve both intensity and frequency of pain. Qualitative studies are needed to reveal the background to these differences.     

Psychosocial Functioning in Schoolchildren With Recurrent Headaches

The psychosocial functioning of 113 schoolchildren (8 to 15 years old) reporting headaches at least once a month was compared to a group of headache-free control subjects matched for sex and age. Thirteen percent of the headache sufferers had migraine headaches, 28% had episodic tension-type headaches, 30% had chronic tension-type headaches, and 29% had migraine coexisting with tension-type headaches.
Overall, the headache sufferers experienced more somatic complaints, stress, and psychological symptoms, in addition to being absent from school (due to illness), more often and reported fewer caring persons as compared to headache-free controls. Although few differences between the four headache groups emerged in the children's psychosocial functioning levels, children with migraine coexisting with tension-type headaches had significantly more frequent somatic complaints than those having episodic tension-type headaches. In addition, children with migraine or migraine coexisting with tension-type headaches were more often absent from school than those having tension-type headaches only. A significant but weak relationship between children's headache severity and their somatic complaints was noted.     

Headache in schoolchildren: association with other pain, family history and psychosocial factors

Limited information exist about associations between different headache types and other pains, family history of pain, and psychosocial factors among children from the general population suffering from less severe headache. We interviewed 130 schoolchildren together with a parent to find out whether such factors differ between children with mainly infrequent and moderate migraine or tension-type headache as compared to those without primary headache. Children with headache, especially those with migraine reported other pains and physical symptoms more frequently than children without primary headache. Coherently, parents of children suffering from migraine reported their children to have significantly more somatic symptoms than parents of children without primary headache. In addition, first-degree relatives of children with headache suffered from more migraine, other pains, and physical symptoms compared with first-degree relatives of children without primary headache. Children with migraine visited the school nurse, used medication and were absent from school because of headache more often than those with tension-type headache. Few other differences in psychosocial factors were found between the three groups. Migraine among first-degree relatives and the total sum of physical symptoms in children were the strongest predictors of headache in logistic regression analysis. It is concluded that in schoolchildren with mainly infrequent and moderate headache, pain and physical symptoms cluster within individuals as well as their families, however, psychological and social problems are uncommon.     

Headache prevalence among adolescents--the German DMKG headache study

This population-based cross-sectional study examined the 3-month prevalence of headache, migraine and tension-type headache (TTH) among adolescents aged 12-15 years in Germany. Students (n = 3324) from 20 schools completed a questionnaire on general and headache-specific pain which included a sociodemographic module. The headache-specific questionnaire complied with the respective revised criteria of the International Headache Society (IHS). 'Modified criteria' changed the item 'duration' in migraine (>30 min instead of > 4 h). The overall 3-month prevalence of headache was 69.4% (boys 59.5%, girls 78.9%), with 4.4% of the adolescents suffering from frequent (>or=14 days/3 months) and severe (grade 8-10 on a 10-point visual analogue scale) headache and 1.4% (boys 0.9%, girls 1.9%) from headache >or= 15 days/month. The 3-month prevalence of migraine was 2.6% (boys 1.6%, girls 3.5%) applying strict IHS criteria and 6.9% (boys 4.4%, girls 9.3%) with modified criteria; 12.6% (boys 8.3%, girls 16.7%) suffered from probable migraine, 0.07% fulfilled the criteria for chronic migraine, 4.5% (boys 4.6%, girls 4.3%) suffered from TTH, 0.2% from chronic TTH and 15.7% (boys 14.5%, girls 16.9%) from probable TTH. Headache and migraine were more common in girls than in boys and in teenagers, especially in girls, aiming at higher education. Recurrent headache and primary headache disorders are common complaints among German adolescents, especially among girls.
