ABSTRACT
An epidemiological evaluation was conducted on 270 patients who died at the General Hospital, Port-of-Spain after presenting with deliberate self-poisoning between January, 1986 and June, 1990. The cause of death was confirmed by autopsy and toxicological analysis. Epidemiological variables of age, sex, race, precipitating factors and types of poison used were assessed. It was found that the male to female ratio was 2.7:1. East Indians accounted for 54.4%, Africans 42.0%, people of mixed ethnic origin 3% and Caucasians 0.6%. The majority of cases (52.6%) were seen in the age group 11-34 years. "Lovers' quarrels" (35.4% of cases), psychiatric illness (27.8% of cases) and family disputes (27% of cases) were reported as the most frequent precipitating events in suicide. East Indians predominated in those suicides precipitated by "lovers' quarrels" and family disputes, accounting for 63.2% and 58.9% of these cases, respectively; while for those suicides in which psychiatric illnesses were the main precipitating event, Africans were represented by 53.3% and East Indians 45.3%. Depression was the most common psychiatric illness diagnosed. Paraquat was the most popular poison used in 63.7% of the suicidal cases, and other agrochemicals were used in 20% of the cases.
