LAINEZ, M. J. A. et al. Impact of several illnesses on Health Related Quality of Life on workers. An. Med. Interna (Madrid) [online]. 2007, vol.24, n.1, pp.3-11. ISSN 0212-7199.

Foundation and objective: To make a comparative study of the degree of impact of different diseases in the health related quality of life (HRQoL) of workers. Material and methods: A questionnaire including the measure of HRQoL SF-36, was sent by mail and fulfilled by employees of the Pfizer company in Spain. Differences in the impact in HRQoL between subjects with and without several characteristics, with less or more degree of work productivity and with and without antecedents of several diseases and current treatment, were assessed by means of statistical tests of U Mann-Whitney and Kruskal-Wallis. Results: In a sample of 399 valuable subjects, 35.8±6.5 years (mean±standard deviation), with a 63.7% of men, worst HRQoL scores in the Physical Summary Component of SF-36 were observed among subjects with history of some disease (52.6±5.9 days versus 55.9±2.6), migraine (46.2±5.9 versus 54.7±4.1), musculoskeletal (49.7±7.2 versus 53.9±5.1) and digestive diseases (51.5±6.6 versus 54.1±4.9), and/or taking some current treatment (50.2±6.4 versus 55.0±4.4); p<0.05 for all comparisons. In the Physical Summary Component of SF-36 worst HRQoL scores were observed among subjects with history of some disease (51.4±7.1 versus 53.4±5.9), digestive (49.9±8.3 versus 52.5±6.3) and mental disorders (46.0±8.8 versus 52.4±6.4); p<0.05 for all comparisons. Conclusions: The impact of the disease in the HRQoL was associated to the type of pathological antecedents, being migraine that hit more negatively in the Physical Health, and mental disorders in the Mental Health.
