title: [Occupational accidents in Municipio Maracaibo, Estado Zulia, Venezuela, 1979-1990. Determination of the frequency and risk factors which play a role in their production].
abstract: During the period of 1979-1990 job-related injuries were studied in Maracaibo, Zulia state, in order to analyze frequencies and causes. This information was obtained from annual reports on job-related injuries Form Number 15-411 of the Venezuelan Institute of Social Security (IVSS) which has been implemented nationally since 1982. Accidents that caused loss of man-hours were considered; variables considered were: age, risk category, day of the week, work shift, month, type of accident, agent, type of lesion, mechanical cause, body part affected and type of the activity in which the company is involved. The results were expressed as absolute values (mean +/- SE) and relative values. The mean accidents/year was 1651 +/- 177.97, most of them occurring in the age groups of 20-29 years (368.8) and 30-39 years (359.8). The triannual mean rate was higher for the group of the non-serious accidents (50%). Tuesday was the day of higher accidental incidence (22%) in addition to the morning shift between 9 and 11 hours (55%). Manufacturing was the economic activity most affected (43%). The most common causative agents were materials, substances and radiations (35%). The use of defective tools were the most frequent causes of mechanical accidents (31%). Upper limbs (46%) and between the type of lesion contusions or/and bruises (53%). It was concluded that, although the number of workers and accidents slowly diminished, the accidents rate slightly increased.
