Indeed, lots of calls for ambition and especially a 9pm watershed for tv junk food advertising. But, critical evidence should underpin these calls, such as this modelling study, which had been available in preprint for a while https://www.repository.cam.ac.uk/handle/1810/307169 https://twitter.com/R_S_P_H/status/1285527743195688960
Shows that if all HFSS advertising between 05.30 hours and 21.00 hours was withdrawn, UK children (n=13,729,000), would see on average 1.5 fewer HFSS adverts per day and decrease caloric intake by 9.1kcal (95 CI: 0.5kcal-17.7kcal)
...which would reduce the number of children (aged 5-17 yrs) with obesity by 4.6% (1.4%-9.5%) and with overweight (including obesity) by 3.6% (1.1%-7.4%) This is equivalent to 40,000 (12,000-81,000) fewer UK children with obesity, and 120,000 (34,000-240,000) fewer with overwt.
For children alive in 2015 (n=13,729,000) this would avert 240,000 (65,000-530,000) DALYs across their lifetime (i.e. followed from 2015 through to death), and result in a health-related net monetary benefit of £7.4 billion (£2.0 billion-£16 billion) to society.
Now that's a benefit worth having. And shouting about. So come on PH Twitter, do your stuff. Paper out in PLoS Med v soon. You're welcome...
