An observational study in Tension-Type Headache, Sleep Disturbance and Smartphone Addiction, sponsored by Assiut University. Not yet recruiting. Open to participants aged 18 Years to 60 Years. Per ClinicalTrials.gov, last updated 2026-08-24.
Sponsored by Assiut University · Observational
To estimate the prevalence of tension-type headache among adults attending the outpatient clinics at Assiut University Hospitals, and to assess its association with smartphone use, sleep quality, and quality of life.
Tension-type headache (TTH) is the most prevalent primary headache disorder and one of the most common neurological disorders. It is characterized by recurrent episodes of mild to moderate headache that are typically bilateral, pressing or tightening in quality, and is not aggravated by routine physical activity. Unlike migraine, TTH is usually not accompanied by nausea or vomiting, although either photophobia or phonophobia may be present. The diagnosis of TTH is based on the International Classification of Headache Disorders, 3rd edition (ICHD-3) criteria.
Tension-type headache is classified according to attack frequency into three main types:
There is a strong association between tension-type headache and smartphone use. There is also increasing evidence for the association of TTH with sleep quality, causing sleep disturbances including insomnia, poor sleep quality, excessive daytime sleepiness, and insufficient sleep. However, there are limited studies in Egypt that have examined the associations between tension-type headache, smartphone use, sleep quality, and quality of life.
143 studies on the registry are indexed under Tension-Type Headache; 42 are open to participants now.
This study's planned enrollment of 199 is above the median of 165 across 30 observational studies indexed under Tension-Type Headache.

Prevalence of Tension-type Headache (TTH) among Adults
Number of adults with tension-type headache diagnosed according to the International Classification of Headache Disorders, 3rd edition (ICHD-3) criteria among those attending the outpatient clinics at Assiut University Hospitals.
Time frame: 1year
Association between Tension-type Headache (TTH) and Smartphone Use
Association between tension-type headache and smartphone use assessed by a structured questionnaire on smartphone usage patterns.
Time frame: 1year
Association between Tension-type Headache (TTH) and Sleep Quality
Association between tension-type headache and sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI). The PSQI is a 19-item questionnaire with a global score ranging from 0 to 21, where higher scores indicate worse sleep quality.
Time frame: 1 year
Impact of Tension-type Headache (TTH) on Quality of Life
Impact of tension-type headache on quality of life assessed by the Short Form-36 Health Survey (SF-36). The SF-36 has scores ranging from 0 to 100, where higher scores indicate better quality of life.
Time frame: 1 year
