[Suicide risk and suicide attempt in North Pas de Calais Region. Lessons from the survey Mental Health in General...

The Santé Mentale en Population Générale Survey (Mental Health in General Population Survey (MHGP)) is a multicentre international research and action project initiated by the World Health Organisation Collaboration Centre for research and training in mental health. Its aims are to assess the prevalence of the major mental health disorders in the general adult population and from this to record perceptions associated with "mental illness", "madness" and "depression" together with different means of assistance and specialist or lay care. In this work we present the analysis of data on risks of suicide and past history of suicide attempts in the Nord pas de Calais region. We present the qualitative features of these phenomena and correlations with socio-economic, cultural and psychopathological factors, which are discussed in terms of both protective and vulnerability factors. Risk of suicide is present in 15% of the Nord pas de Calais population and is divided into 10.44% slight risk, 2.37% moderate risk and 2.2% high risk. A comparison with data from the MHGP survey in other regions reveals the high risk of suicide in the NPDC region. A risk of suicide is present is 13% of the population in other SMPG survey regions, broken down into 9.1% low risk, 2.1% medium risk and 1.7% high risk. Compared to the 2.2% high risk figure for NPDC, the population in this category is 21% larger. In terms of risk and protective factors, a bivariate analysis of socio-economic and cultural factors confirms the classical risk factors of sex, marital, occupational and educational status and income. The odds-ratio for these socio-economic and cultural factors can be calculated from logistic regression and the protective factors ranked in decreasing order from religion (Muslim versus other religions), martial status (marked versus separated), age (over 58 years old), occupational status (working or retired versus unemployed), income (more than 1300 euros versus less than 840 euros), sex (men versus women) and immigration. For mental illness, the bivariate analysis confirms that the risk of suicide is significantly higher regardless of the mental disorder in question. Logistic regression categorises the mental illnesses as risk factors in the following order: depression, psychotic disorders, anxiety, alcohol abuse disorders, other drugs and insomnia. Suicide attempts have been made by 9.7% of the study population. This figure should be compared with the 8% of the study population in other regions in the survey and represents 29% more attempts. For the risk and protective factors the results of the bivariate analysis of socio-economic on cultural and psychopathological factors are superimposeable on those found for risk of suicide. The ranking of protective factors obtained from logistic regression places age in first position followed in decreasing order by religion, martial status, income, employment status and finally sex and immigration. The same ranking of mental illnesses by logistic regression places depression as the greatest risk factor followed by anxiety, psychotic disorders, alcohol abuse disorders, drugs and insomnia.
