title: Body mass index of tannery workers in Kanpur, India.
abstract: During two cross sectional surveys in 1988 and 1994 the body mass index among tannery workers in Kanpur, India and its association with exposure to chemicals, dust and awkward ergonomic conditions, socio-economic and health status were studied. Fifty six per cent of the workers had in 1988 a BMI of less than 18.50, the cut-off value for malnutrition. In 1994 the proportion of malnourished workers had decreased to 41 per cent, being statistically significant lower than in 1988. Workers with a high exposure to lifting weights of more than 20 kg had significantly lower BMI than workers without this exposure. No other differences in mean BMI were found between workers without exposure to chemicals, dust and other awkward ergonomic conditions and workers with high or very high exposures, nor did the mean BMI of workers with occupational related conditions such as dermatitis, work related respiratory symptoms and low back pain differ from those without these conditions. There was no association between mean BMI and industrial modifications. In the 1994 survey workers who took sick leave in the year prior to the survey, workers of small/medium sized tanneries and workers without an ESI card had significantly lower BMI than workers without sick leave, workers of large tanneries and workers with an ESI card. Mean BMI of labourers with a monthly income of less than Rs 550 was significantly lower than that of tannery staff not engaged in leather work in this income group. No association was found between mean BMI and smoking, use of alcohol, educational level and income. The nutritional status of labourers in developing countries deserves more attention within the field of occupational health and safety.
