ABSTRACT
OBJECTIVE: The objective of this systematic review is to synthesize studies on economic burden and economic impact of noncommunicable diseases (NCDs) in the World Health Organization South-East Asian Region (WHO SEAR) countries. INTRODUCTION: WHO SEAR countries represent 8.6% of the world's population and 75% of all deaths in this region are attributable to NCDs. In addition, there is a pattern of low government spending on health in SEAR countries, leading to a high proportion of health financing by patients', risking impoverishment for households. INCLUSION CRITERIA: We will consider observational (cross-sectional, cohort, and case-control) and interventional (either single arm or comparative) studies that report economic burden (direct and indirect costs, out-of-pocket expenditure) and economic impact (catastrophic health expenditure, hardship financing, impoverishment, and gross domestic product impact at individual, household, and/or country levels). This includes government surveys, surveillance, and secondary data analyses for one or more NCDs prevalent in the WHO SEAR. METHODS: We will conduct a comprehensive search for relevant studies in databases, including PubMed (MEDLINE), Embase (Ovid), Scopus, Web of Science, Google Scholar, and gray literature with no date limits. Two independent reviewers will screen titles and abstracts, followed by full-text screening. Included studies will be critically appraised for quality. Data will be extracted accordingly and, if possible, random effects meta-analyses will be conducted on the pooled data for resource utilization and costs (including burden and impact), presenting the degree of variation between studies. The characteristics and results of the included studies will be narratively summarized with accompanying tables. REVIEW REGISTRATION: PROSPERO CRD42023421302.
ABSTRACT
Background: After the National Mental Health Survey in 2016, multiple individual studies showed inconsistencies in the prevalence rates of psychiatric disorders in India. We performed a meta-analysis to estimate an up-to-date pooled estimate of the prevalence of depression, alcohol use disorder (AUD), anxiety disorder (AD), intellectual disability, suicidal attempt/death, autism, and bipolar disorder (BD) in India. Materials and Methods: We performed a systematic bibliographic search in Pub Med, Global Health Data Exchange (GHDx), and Google Scholar, along with a manual search for peer-reviewed epidemiological studies reporting the prevalence of depression, AUD, AD, MR, suicidal attempt/death, autism, and BD in India from January 1980 till March 2022. Adopting a random-effects model, we performed the meta-analysis using "MetaXL" software. Results: A total of 79 studies were included: depression (n = 28), AUD (n = 14), AD (n = 12), intellectual disability (n = 8), suicidal attempt/death (n = 7), autism (n = 6) and BD (n = 4). The pooled prevalence of depression and AUD was 12.4% (95% CI 9.4-15.9) (P < 0.001, I2 = 100%) and 21.5% (95% CI 14.1-30.0) (P < 0.001, I2 = 100%), respectively. AD, intellectual disability and suicidal attempt/death showed a prevalence of 11.6% (95% CI 8.1-15.7) (P < 0.001, I2 = 99%), 1% (95% CI 0.5-1.6) (P < 0.001, I2 = 98%) and 0.5% (95% CI 0.3-0.8) (P < 0.001, I2 = 100%), respectively. The meta-analysis in autism and BD showed pooled prevalence of 0.3% (95% CI 0.1-0.6) (P < 0.001, I2 = 96%) and 0.3% (95% CI 0.2-0.4) (P < 0.001, I2 = 78%), respectively. Subgroup analysis showed an increased prevalence of AD in the urban [24.3% (95% CI 3.7-52.9)] and younger [16.7% (95% CI 5.1-32.7)] population. The prevalence of depression and AD increased during the last two decades on decadal prevalence analysis. Discussion: The findings could be used for appropriate policy measures and guiding subsequent national mental health surveys.
