West Bengal, situated in eastern India, comprising 19 districts as of 2016 and consisting of 9.13 crore population, had been one of the participating states in the National Mental Health Survey, 2015-16.
To estimate the prevalence and pattern of mental disorders in a representative population in West Bengal.
Based upon a multi-stage stratified random cluster sampling with probability proportionate to each stage, 2646 eligible individuals were interviewed. Standard validated instruments in Bengali like socio-demographic profiles and Mini International Neuropsychiatric Interview (MINI) version 6 were used by trained data collectors with quality monitoring as per a standardized protocol.
The current prevalence of mental illness in the state of West Bengal is 13.07% (12.9-13.24 95% CI), which is more than the current national average of 10.56% (10.51-10.61 95% CI). The prevalence of severe mental illness of 2.32% and suicide risk of 1.75% (1.68-1.81 95% CI) is higher than the national average. The common mental illness prevalence is 11.29 (11.13-11.45 95% CI), which is similar to the national weighted average. In West Bengal, severe mental illness is more concentrated in the rural areas in contrast to the national trend. Also, the prevalence of alcohol use disorder is 3.04 (2.96-3.13 95% CI) and epilepsy is 0.03 (0.27-0.29 95% CI), which is less than the national average.
The prevalence of mental disorders in the state of West Bengal is higher than the national average, and for severe mental illness, the prevalence is the highest as compared to the national average.
西孟加拉邦位于印度东部，截至2016年包括19个区，人口达9130万，是2015 - 2016年全国精神卫生调查的参与邦之一。
估计西孟加拉邦具有代表性人群中精神障碍的患病率及模式。
基于多阶段分层随机整群抽样，各阶段按概率比例抽样，对2646名符合条件的个体进行访谈。经过培训的数据收集者使用孟加拉语的标准验证工具，如社会人口学概况和迷你国际神经精神访谈（MINI）第6版，并按照标准化方案进行质量监测。
西孟加拉邦目前精神疾病的患病率为13.07%（95%置信区间为12.9 - 13.24），高于目前全国平均水平10.56%（95%置信区间为10.51 - 10.61）。严重精神疾病的患病率为2.32%，自杀风险为1.75%（95%置信区间为1.68 - 1.81），高于全国平均水平。常见精神疾病的患病率为11.29（95%置信区间为11.13 - 11.45），与全国加权平均水平相似。与全国趋势相反，西孟加拉邦的严重精神疾病在农村地区更为集中。此外，酒精使用障碍的患病率为3.04（95%置信区间为2.96 - 3.13），癫痫患病率为0.03（95%置信区间为0.27 - 0.29），低于全国平均水平。
西孟加拉邦精神障碍的患病率高于全国平均水平，且严重精神疾病的患病率与全国平均水平相比最高。
