“…We also found one general-adult, population-based estimate for the pooled prevalence of any mental disorder, covering all countries in SA except Maldives and presented as a rate per 1000 (95% CI): 122.0 (8.0-252.0) (Ranjan and Asthana, 2017). In addition, we found two meta-analyses reporting SUDs prevalence of 0.0% (0.0-1.0) to 32.0% (6.0-78.0) (Naveed et al, 2020;Zuberi et al, 2021), one on dementia prevalence (2.0% (2.0-3.0)) (Choudhary et al, 2021) and one on ASD prevalence (0.1% (0.0-0.2)) (Chauhan et al, 2019). These are not presented in Figure 2.…”

Mental disorders are increasing in South Asia (SA), but their epidemiological burden is under-researched. We carried out a systematic umbrella review to estimate the prevalence of mental disorders and intentional self-harm in the region. Multiple databases were searched and systematic reviews reporting the prevalence of at least one mental disorder from countries in SA were included. Review data were narratively synthesised; primary studies of common mental disorders (CMDs) among adults were identified from a selected subset of reviews and pooled. We included 124 reviews. The majority (n = 65) reported on mood disorders, followed by anxiety disorders (n = 45). High prevalence of mental disorders and intentional self-harm was found in general adult and vulnerable populations. Two reviews met our pre-defined criteria for identifying primary studies of CMDs. Meta-analysis of 25 primary studies showed a pooled prevalence of 16.0% (95% CI = 11.0–22.0%, I 2 = 99.9%) for depression, 12.0% (5.0–21.0%, I 2 = 99.9%) for anxiety, and 14.0% (10.0–19.0, I 2 = 99.9%) for both among the general adult population; pooled estimates varied by country and assessment tool used. Overall, reviews suggest high prevalence for mental disorders in SA, but evidence is limited on conditions other than CMDs.

“…This would equate to approximately 3.9 million people living with dementia in India, when based on population projections for older adults living in India in 2021 ( National Commission on Population, 2020 ). One systematic review estimated the dementia prevalence to be 2% in India 1 ( Choudhary et al, 2021 ). Despite high quality synthesis, we should be cautious not to assume that such estimates are definitive.…”

“…As a result of differences between prevalence estimates and individual study reporting styles, it can be difficult for systematic reviews to extract data to obtain more granular estimates (e.g., age, sex) in a meta-analysis. For example, very few systematic reviews (e.g., Choudhary et al, 2021 ) from India have provided prevalence of dementia split by age and sex, despite individual studies reporting on them. In addition, there are also considerable gaps in the existing evidence base, which makes it difficult to compile such data.…”

Estimating the number of people living with dementia at different stages of the condition in India: A Delphi process

Introduction Numerous studies have previously estimated the dementia prevalence in India. However, as these estimates use different methodologies and sampling strategies, generating definitive prevalence estimates can be difficult. Methods A Delphi process involving eight clinical and academic experts provided prevalence estimates of dementia within India, split by sex and age. The experts were also asked to estimate the number of people potentially living at different stages of the condition. A priori criteria were used to ascertain the point in which consensus was achieved. Results Our consensus estimates generated a dementia prevalence of 2.8% (95% CI = 1.9 to 3.6) for those aged 60 years and above in India. Consensus was achieved across age and sex prevalence estimates, with the exception of one (females aged 60–64). Our experts estimated that 42.9% of people living with dementia in India had a mild severity. Conclusions The findings indicate that there could be approximately 3.9 million people living with dementia in India, of which 1.7 million could be living with dementia of mild severity. Such estimates can better help researchers and policy makers to estimate the true cost and impact of dementia in India and can inform resource allocation decisions.
