However, some studies have found prevalence rates of between22% and 17% in the country, depending on the age group included and the scope of the study.
Studies conducted in recent decades in children under the age of six have found prevalence in a 20 to 70% range.
Dr. Piot said that surveys in the states of Maharashtra, Andrha Pradesh and Tamil Nadu, each with populations of at least 55 million, have found prevalence rates of at least 2percentt among pregnant women and more than 10percentt among patients with other sexually transmitted diseases.
The found prevalence rate in our study is thus located in the lower range of previously reported rates.
In addition, we found prevalence rates of 2.02 % for TTH, 0.85 % for MIG, 3.79 % for CH, and 3.63 % for UNC among all study participants.
Studies using the first International Headache Society criteria (IHS, 1988) found prevalence rates of between 3 and 11% in the general population [5, 6].
Studies of PTSD among military and police personnel have found prevalence estimates of 8.3% (Defence Health 2016) and 10 12% (Rose et al. 2002) for these populations respectively, compared with 4 6% of the general population (Cooper et al. 2014).
Drawing on diverse studies of AI/AN populations, Buchwald et al. (2000) found prevalence estimates of abuse ranging from 2% to 46% among AI/AN populations (Minton and Soule 1990; John 1995 in Buchwald et al. 2000) (Table 3).
A population-based study in South Africa and another in Zambia found prevalence of depression between 5 15% [25], [43].
Recent X-ray surveys performed in three RJ prisons found prevalence rates of active TB ranging from 4.6 to 8.6% [4], [5].
A recent study in Mumbai found prevalence rates of MDR TB to be 24% among newly diagnosed, previously untreated patients and rates of 41% among first-line drug failures[20].
