The GBD2010 DW for the ictal state of TTH was only 0.04 [34], so the mean estimated disability attributed to TTH per adult with the disorder would be quite low.
The mean proportion of total time spent in the ictal state was 7.3% (100*[1.5*34.9]/[30*24]%) and the disability level (mean disability attributed to TTH per adult with the disorder) was 0.27% (0.037*7.3%).
The World Health Organization (WHO) has estimated that 40% of disability attributed to anxiety reflects the fact that many potential anxiety patients never reach health care [ 1].
Disability level (the mean disability attributed to migraine per adult with the disorder), estimated by applying the GBD2013 DW of 0.441 for the ictal state of migraine [29], was 5.2% (0.441*11.7%).
At the same time, the study found that the prevalence of disability attributed to other chronic conditions decreased, while the prevalence of significant mental distress remained unchanged.
This was the mean estimated disability attributed to migraine per adult with the disorder in Zambia.
Disability level (mean disability attributed to pMOH per adult with the disorder) was 13.4% (0.223*60.2%).
Anxiety, depressive and substance use disorders account for three quarters of the disability attributed to mental disorders and frequently co-occur.
This trial is registered with the Australian and New Zealand Clinical Trials registry, ACTRN12613000723785. Substance use, anxiety and depressive disorders account for three quarters of the disability attributed to mental disorders [ 1].
Thus the mean estimated disability attributed to MOH per adult with this disorder would be 8.3% (0.220*37.5%).
