Indians in white-collar jobs more prone to obesity, chronic health risks
Indians in white-collar jobs, with low levels of activity in their workday, have a higher average body mass index (BMI)--an indicator of obesity--than those in blue-collar occupations, according to a new study.
Engineers, technicians, mathematicians, scientists and teachers, for example, had higher BMIs than farm workers, fisherpeople and housekeepers, concluded the study published in the journal Economics and Human Biology.
BMI is derived by dividing an individual’s body mass by the square of the body height and is expressed in units of kg/m2. The average BMI of men in white-collar jobs was 1.17 kg/m2 higher than those in blue-collar occupations; among women, the difference was 1.51kg/m2, the study showed. A lower BMI is better than higher.
Individuals are categorised as underweight if their BMI is under 18.5 kg/m2, normal if it is in the range of 18.5 to 25 kg/m2, overweight if it is somewhere between 25 and 30 kg/m2 and obese if the index surpasses 30 kg/m2, according to the standards prescribed by the World Health Organization (WHO).
India has experienced high rates of economic growth in the last two decades, and the resultant increase in income is related to a rise in the proportion of those who are obese, according to this study.
India currently has the third highest number of overweight or obese individuals among all countries--20% of its adults and 11% of adolescents can be categorised as obese, according to this September 2014 paper, that has been cited in this study.
