Tempo de afastamento por doença em trabalhadores do Estado do Amapá no período de 2008 a 2012

Abstract

Work-health–disease relations always been observed throughout mankind history, and despite being initially unexplored, with the development of new production methods and technological advances, came the need to better understand the mechanisms and patterns of disease in workers. In this context, the working-age population with affiliation to the Brazilian social security system is important to identify the morbidity situation of Brazilian workers. This research aimed to evaluate the morbidity in workers, identifying the most frequent deseases, the average work-lost in days of labour disability and its association with disease variables, gender, age, profession, city of residence and salary of workers in Brazilian state of Amapá covering 2008-2012 period. This research used the cross-sectional approach and quantitative data analysis, retrieved from National Institute of Social Security (INSS) informations systems. Statistical analysis was performed to determine the measures of central tendency and variation of the dependent variable and the independent variables, as well as assess the statistical significance (alpha=0.05), and to determine the association among work-lost in days and research variables. This study identified 10,216 cases of temporary work disability benefits in the state of Amapá during 2008-2012 period, 69.3 % of cases were men , 83.4 % temporary non work-related disability benefit, were aged 30-39 years ( 29.6 %), monthly income corresponding to one Brazilian minimum wage (50.6 %), formal employees (65.1 %), 84.2 % from Amapá municipalities and 86.1 % workers from service sector. This research identified average of 61.5 work-lost days due deseases. Diseases identified as External Causes (41.2 %), Other Diseases (15.9%) and Musculoskeletal Deseases (14.1%) accounted for the largest number cases and average 73, 28 and 57 work-lost days, respectivily. The variables age, salary, type of social security affiliation, city of residence, work sector and type of desease influenced the time of work-lost days. At the period Amapá presented a median of 53 days and the interquartile range in the interval between 29 and 83 days, and this range considered normal in this population. The practical use of these information can serve as a basis for the development of information systems that can support dynamic evaluations of work disability to better define the optimal time of work-lost days for a population taking as variables local standards. Through the results, it is expected to broaden the debate on the policies of the worker’s health in Amapa, as well in Amazon region, since the identification of the characteristics of morbidity in the study area will allow comparative analyzes with other areas of the country
