Background. The aim of the present study was to estimate prevalence rates of psychiatric and substance use disorders in male and female prisoners on admission to prison in the north of France and compare the frequency of these disorders to the general population. Methods. This cross-sectional survey on Mental Health in the Prison Population (MHPP), conducted between March 2014 and April 2017, interviewed 653 randomly selected men and women who had recently been committed to the French general population prison system in the Nord and Pas-de-Calais departments. For each subject, the Mini International Neuropsychiatric Interview (MINI), a standardized psychiatric interview, was used to screen for psychiatric and substance use disorders. The prevalence rates were then compared with data from the Mental Health in the General Population (MHGP) survey, a general population survey that used the same assessment methodology as MHPP in the Nord and Pas-de-Calais departments. A control sample was taken from the MHGP survey with a ratio of one case (MHPP) to three controls (MHGP) matching on age and sex. Results. The sample was primarily composed of French men, most of them single with low educational levels at the time of imprisonment. The mean age was 31.7 (standard deviation = 9.9; min = 18; max = 67). Most of the subjects included were first-time prisoners. The prevalence of affective disorders among newly incarcerated individuals was 31.2% with higher rates for major depressive disorder (27.2%). The prevalence of anxiety disorders was 44.4% with higher rates for generalized anxiety disorder (25.2%). The prevalence of psychotic syndromes was 6.9%. The prevalence of substance use disorders was 53.5% and a suicide risk was identified in 31.4% of the prisoners interviewed. Higher prevalence rates were found in the MHPP when compared with the MHGP for all psychiatric and substance use disorders assessed except for dysthymia and current isolated psychotic syndrome. Conclusions. Our study shows very high levels of prevalence for psychiatric and substance use disorders in recently committed French prisoners.

入狱时的精神障碍：流行率研究以及与法国北部社区样本的比较

背景。本研究的目的是估计法国北部入狱时男性和女性囚犯精神和物质使用障碍的患病率，并将这些障碍的频率与一般人群进行比较。方法。这项关于监狱人口心理健康 (MHPP) 的横断面调查于 2014 年 3 月至 2017 年 4 月期间进行，采访了随机选择的 653 名男性和女性，这些男性和女性最近被关押在 Nord 和 Pas-de 的法国普通监狱系统中- 加来部门。对于每个受试者，迷你国际神经精神病学访谈 (MINI) 是一种标准化的精神病学访谈，用于筛查精神病学和物质使用障碍。然后将流行率与普通人群中的心理健康（MHGP）调查的数据进行比较，一项一般人口调查，该调查使用与北部省和加来海峡省的 MHPP 相同的评估方法。对照样本取自 MHGP 调查，其中一个病例 (MHPP) 与三个对照 (MHGP) 的年龄和性别匹配。结果。样本主要由法国男性组成，他们中的大多数在监禁时单身且受教育程度低。平均年龄为 31.7（标准偏差 = 9.9；最小值 = 18；最大值 = 67）。包括的大多数受试者是初犯。新入狱者中情感障碍的患病率为 31.2%，重度抑郁症的患病率更高 (27.2%)。焦虑症的患病率为 44.4%，广泛性焦虑症的患病率为 25.2%。精神病综合征的患病率为 6.9%。物质使用障碍的患病率为 53。5%，31.4% 的受访囚犯有自杀风险。与 MHGP 相比，除了心境恶劣和当前孤立的精神病综合征之外，所有精神病和物质使用障碍的患病率都高于 MHPP。结论。我们的研究表明，在最近入狱的法国囚犯中，精神疾病和物质使用障碍的患病率非常高。
