Risks and Comorbid Factors of Frequent Headaches during Childhood and Adolescence

Background: The prevalence of headache during adolescence is very high. In most studies, the prevalence of headache is higher in females. The objective of the present study was to evaluate statistically significant associations between high headache frequency and multiple variables obtained in a National Survey. Methods: The included variables were demographic and socioeconomic; other health complaints; sleep characteristics and complaints; current adolescents´ habits concerning multimedia/electronic tools and nutrition variables; risk behaviors; social support and school satisfaction with the final purpose of building a risk association model for adolescents´ frequent headaches by means of a logistic regression. This survey is a component of the Health Behavior in School-Aged Children (HBSC) study. The Portuguese HBSC survey included 3476 pupils (53.8 % girls) in the 8th (45.9%) and 10th grades (54.1%) with a mean age was 14.9 years (SD=1.26). Results: The prevalence of high-frequency headaches was 22.2% and their major comorbidities were other health complaints with special reference to abdominal pain and dizziness and psychopathological symptoms, namely sadness, irritability, nervousness and low energy. Furthermore, they had lower family support, lower academic success, unfair treatment, loneliness and nobody to share or to worry about their problems and lower quality of life; e-media and excessive mobile phone use, tobacco and alcohol use, and some violent behaviors were also associated with the presence of frequent headaches. Conclusion: In spite of these significant associations, the logistic regression model explaining 38% of the variance included mostly other health complaints.
