WHO report claiming half of India's population is physically unfit is based on extrapolations: Nadda
The Hindu
WHO report on India's physical activity levels questioned by Union Health Minister due to methodological issues.
The WHO's recent report stating that half of India's adult population is physically unfit relied on data collected only from three states and one UT, and the results were extrapolated through a modelling technique indicating inbuilt methodological issues, Union Health Minister J P Nadda told the Lok Sabha on Tuesday.
Responding to a question, Mr. Nadda said the WHO defines 'sufficient physical activity' as 150 minutes of moderate intensity physical activities per week (brisk walk, lifting light load etc.) or 75 minutes of vigorous intensity activity per week (running, digging, construction work, outdoor games etc.).
The activity level so quantified is based on a self-reported response to questions about physical activity lasting at least for 10 minutes.
The National NCD Monitoring Survey of Indian Council of Medical Research (ICMR) 2020 has assessed, inter alia, physical activity amongst Indian adults and found that 58.7 per cent had conformed to the WHO recommendations, Mr. Nadda told the Lok Sabha.
He informed that the ICMR in another study entitled 'Physical activity and inactivity patterns in India' results from the ICMR-INDIAB Study (phase 1) conducted in 2014 has found that 54.4% of the sampled adult population were insufficiently physically active.
The study findings were based on the data collected from three States — Tamil Nadu, Maharashtra and Jharkhand — and Union Territory of Chandigarh.
Based on this ICMR-INDIAB Study (Phase 1) data, the WHO in collaboration with Lancet published an article entitled "National, regional and global trends in insufficient physical activity among adults from 2000 to 2022: a pooled analysis of 507 population based surveys with 5.7 million participants" and reported enhanced prevalence of insufficient physical activity among Indians between 2000 (22.3%) and 2022 (49.4%).
