The prevalence of head and face pain decreased from 1997 to 2017 in Switzerland.

Background: Pain in the head and the face is highly prevalent but may have changed during the past years. This study aimed to analyze changes in the prevalence of pain in the head and the face in Switzerland from 1997 to 2017.

Methods: This is a secondary analysis of data collected in the Swiss Health Surveys of 1997-2017. Included persons were 15 years and older. Besides studying demographic data, we analyze the item assessing the presence of "headache, pressure in the head, or facial pain" during the past 4 weeks. Percentages with their Wilson confidence intervals are reported for each response option of categorical variables. Moreover, we calculate the age-standardized number of persons affected by the pain.

Results: While 41% reported head and face pain in 1997, the proportion dropped to 31% in 2017. There was a decrease of 19.5% in women and 29.4% in men; after age standardization, the decrease was 16.5% in women and 25.4% in men. The most considerable numerical changes in the percentages of women with pain occurred in those aged 55-69 and 85 and above. In men, the changes were not limited to specific age groups.

Conclusions: The proportion of people reporting headaches, pressure in the head, or facial pain has dropped in Switzerland from 1997 to 2017. However, in women, the prevalence diminished more strongly and consistently in the middle-aged and the elderly than in the young.
