Lifestyle, quality of life, nutritional status and headache in school-age children.
Headache has been described as a factor with significant negative impact on the quality of life of school-aged children with a high risk of developing in chronic and persistent form in adulthood. Among other headache associated triggers or aggravating factors, lifestyle and obesity has been investigated, but results are still conflicting. To evaluate the prevalence of headache in school-aged children and its relationship to anthropometric characteristics, lifestyle, and quality of life. A cross-sectional study was conducted in six schools located in two cities in southern Brazil, involving 750 students aged 7 to 14 years. Information was collected on sociodemographic characteristics, clinical variables (presence of headache and menarche), anthropometric data, lifestyle, and quality of life. A total of 185 (24.7%) students reported having headache crises in the last 3 months. Among students aged 10 to 14 years, presence of headache was associated with female sex, affecting 32.2% of girls vs. 23.3% of boys (p = 0.042, chi-square test). Anthropometric parameters (data on overweight/obesity) were consistent with national prevalence rates, and there was no association between Body Mass Index (BMI) and headache. Regarding lifestyle, 2.0% of students reported smoking and 1.6% consuming alcohol occasionally, and neither was associated with headache. Quality of life, especially aspects of social life, appeared to be affected by the presence of headache. This study found a high prevalence of headache in school-aged children, which was associated with female students aged 10-14 years and quality of life.
