Many factors can contribute to suicide. The psychological drivers, however, are most examined. This focus on mental factors is supported by the global hegemony of the medical-psychiatric model. This is reflected in the global focus on preventing suicide by detecting and treating mental risk factors. Other factors that contribute to suicide, such as culture, receive less attention.

This paper examines the relationship between transnationalism, cultural preservation, and transgenerational trauma in the United States (US) Indo population. The information being analysed was compiled by the author from two separate surveys which took place between 2012 and 2021. This data was initially intended to act as a census for the scattered US Indo community however the salient information necessitated that the census be ongoing and that another survey be developed to measure effects of lingering trauma which has been passed down generationally.

Because of the rapidly increasing number of randomised controlled trials (RCTs) and meta-analyses in many fields, there is an urgent need to step up from meta-analyses to higher levels of aggregation of outcomes of RCTs. Network meta-analyses and umbrella reviews allow higher levels of aggregation of RCT outcomes, but cannot adequately cover the evidence for a whole field.

Question: Effective prevention of suicide requires a comprehensive understanding of risk factors.

Study selection and analysis: Five databases were systematically searched to identify psychological autopsy studies (published up to February 2022) that reported on risk factors for suicide mortality among adults in the general population. Effect sizes were pooled as odds ratios (ORs) using random-effects models for each risk factor examined in at least three independent samples.
