The pattern of morbidity and its effects on productivity of factory workers in Kenya.
A retrospective study was carried out from January to September 1990 in a factory that manufactures textiles in Eldoret, Kenya. Over the study period, 1400 factory workers had 303 episodes of illness resulting in a loss of 720 productive man-days. This is an incidence of 289 episodes of illness per 1000 workers per year. On average, each episode of illness resulted in 2.4 man-days loss. Of all the episodes of illness, 58.8% were attributable to infective and parasitic diseases, 10.9% to respiratory system disorders and 21.7% to other conditions. Malaria constituted 53.1% of all episodes of illness, acute respiratory infection (ARI) 10.9%, physical injuries 5.6%, gastro-enteric illnesses 3.4% and other conditions 21.7%. For the productive man-days lost, 53.2% were attributable to malaria, 12.8% to ARI, 5.7% to physical injuries and 28.3% to other conditions. Abortions and worm infections resulted in loss of 7.0 man-days per episode of illness, diarrhoea 3.2, myalgia 3.0, ARI 2.8, eye diseases 2.7 and the rest below the average of 2.4 days. Apart from the physical injuries, there were no other occupational illnesses in the textile factory workers. Episodes of illness that occur during the last and the first week of the month constitute 61.0% of all illnesses. Mondays had 24.4% of the episodes of illness, Sundays 7.9% with the other days of the week constituting an average 13.5%.
