Re: Cardiovascular risk profile among industrial workers in North India: A cross-sectional study

In this study, Mohan et al found that, of the 15,527 industrial workers in Ludhiana, North India, 22% had hypertension, of which 85% was undiagnosed and 11% had diabetes. Three methodological issues discussed in this commentary are worthy of consideration: firstly, the implications of the largely migrant male workforce for generalisability; secondly, the lack of a structured cardiovascular risk-scoring system to put individual risk factor prevalence into context; and, thirdly, the need to consider occupational exposures (such as noise, shift work and heat stress) as separate cardiovascular risk factors not included in the study's risk profile.
