Relación edad y accidentabilidad en trabajadores del sector forestal en Chile / The relation ship between age and accident rates in workers from the forest industry

Atendiendo a las tendencias observadas sobre envejecimiento de la población mundial y su incidencia en la fuerza laboral, la Asociación Chilena de Seguridad realizó un estudio de aproximación a dicho problema en empresas forestales e industrias de la madera afiliadas, investigando la evolución de la tasa de accidentalidad, tasa de siniestralidad por incapacidades temporales y promedio de días perdidos por accidente según rangos de edad en trabajadores lesionados entre los años 2004 y 2008. El universo del estudio comprendió una población media de 55.098 trabajadores, distribuidos en un promedio de 1.871 empresas. En forma complementaria se realizó también un análisis comparativo casuístico sobre evolución de la participación porcentual de los trabajadores lesionados según rango de edad entre los quinquenios1998-2002, 2001-2005 y 2004-2008.Los resultados generales revelan que luego de una bajísima accidentalidad y siniestralidad en trabajadores menores de 18 años, estos indicadores pasan violentamente a valores máximos en el rango 18-20 años, para luego declinar progresivamente, como es el caso permanente en la tasa de accidentalidad. En cambio, para la tasa de siniestralidad por incapacidades temporales la disminución se detiene alrededor de los 40 años, edad desde la cual se reinicia un incremento lento y permanente hasta los 60-99 años. Por otro lado, el promedio de días perdidos por accidente presenta una relación directa de aumento en gravedad con el avance en edad, el que mantiene una fuerte inclinación positiva. Respecto al porcentaje de lesionados según edad, este valor aumenta entre quinquenios desde el rango 36-40 años en adelante.

In accordance with tendencies of world population ageing and its incidence in workforce, the Asociación Chilena de Seguridad conducted an approximation study of ageing in forest companies and wood industries. The evolution of accident rate, risk rate and average lost time per accident were analyzed according to age range in workers injured between 2004 and 2008. The universe of the study was constituted by a mean population of 55,098 workers distributed through an average of 1,871 companies. Additionally, a comparative case-based analysis about evolution of percentage participation of injured workers was also carried out, according to age range between five-year periods: 1998-2001, 2001-2005 and 2004-2008. General results indicate that after a very low accident and loss rates in workers under 18 years of age, these indicators drastically change into maximum values in age range 18-20 years, and subsequently decrease gradually. This is a permanent case in the accident rate, but results for the loss rate due to temporary incapacity show that this decrease stops about the 40 years of age, from which starts a low and permanent increase until the age range 60-99 years of age. On the other hand, the mean of lost days due to accident presents a direct relationship of increase in seriousness with the advance of age that maintains a strong positive tendency. With regard to the percentage of injured workers according to age, this value is higher between five-year periods from 36-40 years on.
