Although period prevalence figures, which are those generally provided in research into rates of mental disorder among prisoners, are useful for planning improvements to services within prisons, the fact that almost all of these men had a lifetime prevalence of at least one mental disorder suggests a much wider need for improving services, including community services, for this group.

The data from a Spanish prison population showed that ID levels were higher than those in the community, especially amongst prisoners requiring specialized psychiatric care. What is also evident is that adequate resources are required in prisons and in the community to provide better care for people with intellectual disabilities who are in the pathway of the criminal justice system.

Old age population is growing steadily during last decades (WHO 2017). Old population suffer from more morbidity including mental disorders (De Lorito,2018). This fact also applies for prison population (Yortons 2006) and in the lasts years has been an increasing interest for this topicThe aging of the world population is reflected in the penitentiary setting, with a progressive increase of elderly inmates. These prisoners present complex clinical processes with multiple comorbidities, requiring a specialized approach. In the 2020, the old age population in prison (considered over 60 years old) is around 5% in Catalonia (377 inmates,), same proportion (5%) in Spain.If we consider the cut-off point 50 y.o. (as other research) the proportion is 12% Our aims are to describe sociodemographical and clinical characteristics of old age inmates (over 50 y. o.) who required to be admitted to psychiatric unit in Catalan prisons between 2016 and 2020. The asample of this study will be around 150 inmates admitted in our unit. Elderly inmates present a high prevalence of substance abuse (especially alcohol), affective symptoms (depression) and cognitive deterioration. Likewise, is observed a significant presence of personality disorders, anxiety, post-traumatic disorders, psychotic disorders, and physical comorbidities. Prisoners over 50 have a different profile from the rest of the prison population. They suffer more physical and mental illnesses, so they require specific health and social approach. It would be advisable to adapt clinical care by optimizing resources, developing prison psychogeriatrics and establishing specific evaluation and treatment method Disclosure No significant relationships.

The succes results in the pegylated interferon plus rivabarina therapy in HCV-infected people has made an increase of the prescription of this treatment in the last years. Side-effects of the pegylated inclose the neuropsychiatric symptoms as depressive and anxiety both simptoms and disorders. The prevalence of depressive disorders has been described between 22%-38%, while the depressive symptoms between 21% and 64%. In the penitentiary field, both the prevalence of HCV and depression are higher than in general population. The aim our study is to know the prevalence od depressive disorders in a population of HCV- infected inmates treatede with pegylated interferon. This inmates in the Centre Penitenciario Quatre Camins, (n:40) were administered the following depression scales. Hamilton Depression Scale (HDRS), Montgomery-Asberg Depression Scal (MADRS) and Hospitalary Anxiety and Depression Scale (HAD). These scales were passed at basal, 1-month, 3-month, ending of treatment and 3 month after finising the treatment. Data was collected regarding HCV infection(genotype, interferon dose, etc.), comorbidity, and psychiatric background and psychopharmacological treatment. All the particpants were informed about the study and ask about their agreement.Inmates population in CP Quatre Camins (Prison) is about 1800, which 723 have positive serology to HCV. From this group 40 inmates were treated with interferon. Regarding the genotype of HCV, 55% were genotype 1, l 33% genotype 3 and 12% genotype 4. HIV Comorbidy is the l 21%.Preliminary data about depression disorder point to a prevalence of a modertae depressive disorder in 12,5% of inmates.

Introduction: The relationship between violent offences, mental disorder and substance-use disorders has been widely analyzed but has produced contradictory results. Studies examining this relationship in prison populations are scarce. Objectives: The aim of the study was to analyze the relationship between violent crime, substance-use disorders and mental disorder. Method: This is a descriptive, cross-sectional, epidemiological study of 707 male prisoners. Socio-demographic, clinical and penal data were collected by trained interviewers. Penal data were confirmed using penitentiary records. The clinical version of the Structured Clinical Interview (SCID 1) for DSM-IV Axis I Disorders was used for diagnosis of Axis I mental disorders (including substance-use disorders). Inmates who have lifetime substance-use disorders were classified by type and number of substances used. We considered violent offences: homicide and attempted homicide, aggravated assault, common assault, robbery, threatening behavior, harassment, arson and any sexual offence. Results: Violent offences in inmates who used drugs (n=370) were more prevalent than in inmates who did not (84.6% vs.15,3%, p<0.0001).The risk of committing a violent crime is double for people using a substance compared to those who do not and those who are not repeat offenders (OR= 2.03 CI 95%: 1.08-3.78). This risk increases when considering repeat offenders and those who use more than one substance . The presence of a mental disorder turns out not to be significant (OR= 1.38 CI 95%: 0.98-1.95). Conclusions: In our study, the greatest risk factors for committing a violent offence were being a re-offender and using more than one substance. Mental disorder was not found to be a risk factor for violent offences.
