Mental health services for homeless: patient profile and factors associated with suicide and homicide.

This study aimed to establish a profile of users of the mental health service for homeless in Cork, comparing this group with those attending a General Adult Service. The homeless group were significantly more likely to be male (89% v 46%), unemployed (96% v 68%), unmarried (98% v 75%) and under 65 (94% v 83%). Diagnostically, there was a significantly higher prevalence of schizophrenia (50% v 34%); personality disorder (37% v 11%) and substance dependence (74% v 19%) in the homeless service users. They were more likely to have a history of deliberate self harm (54% v 21%) and violence (48% v 10%). Severe mental illness has a high prevalence in the homeless population, with particularly high levels of factors associated with suicide and homicide. Poor compliance and complexity of illness lead to a requirement for significant input from multidisciplinary mental health teams members.This resource was contributed by The National Documentation Centre on Drug Use.

Vitamin D and Health

SACN reviewed the evidence on vitamin D and health to see if UK dietary recommendations, set in 1991, were still appropriate. In addition to the main report, you can read the SACN press release. In a change to previous advice, SACN is now recommending: a reference nutrient intake (RNI) of 10 micrograms of vitamin D per day, throughout the year, for everyone in the general population aged 4 years and older an RNI of 10 micrograms of vitamin D per day for pregnant and lactating women and population groups at increased risk of vitamin D deficiency a ‘safe intake’ of 8.5 to 10 micrograms per day for all infants from birth to 1 year of age a ‘safe intake’ of 10 micrograms per day for children aged 1 to 4 years The RNI and safe intakes were developed to ensure that the majority of the UK population has enough vitamin D to protect musculoskeletal health, all year round. SACN did not take account of sunlight exposure in making recommendations because of the number and complexity of factors that affect skin synthesis of vitamin D. The RNI and safe intakes refer to intake from all dietary sources: natural food sources fortified foods (including infant formula milk) supplements They also refer to average intakes over a period of time, such as a week, and take account of day-to-day variations in intake.
