Barbara Paterson, deputy director of health and wellbeing at PHE East of England said: "Although we have not seen a huge increase in child obesity rates in the region, these latest figures should still be a wake-up call as no child should suffer with obesity - our children need every opportunity to enjoy a healthy life when they are young and to avoid developing serious health problems such as diabetes, heart and liver disease".
Record numbers of children are leaving primary school fat with one in five now obese, shocking figures suggest.
Regional data included in the 2016-17 report show how obesity prevalence varies by local authority.
In Kingston upon Thames, south-west London, 4.8% of children in reception are obese, compared with 13.5% in Wolverhampton.
In year 6, 11.3 per cent of pupils in Rutland were obese, rising to 29.2 per cent in Barking and Dagenham.
"Childhood obesity is the challenge of a generation and we need to take collective joined-up action both locally and nationally to give our children the future they deserve". A measurement between 25 and 30 is considered overweight, and a measurement in excess of 30 is considered obese.
Deprived areas of the country are particularly affected by obesity, with more than double the number of obese children compared to more affluent areas.
Caroline Cerny, head of the Obesity Health Alliance, a coalition of more than 40 organisations including charities, said: "Each year the childhood obesity statistics tell the same devastating story".
"At a time when action is badly needed, councils are struggling to find funds to support childhood obesity prevention and the government's childhood obesity plan is over-reliant on voluntary measures and working with industry, despite its welcome commitment to the sugar levy". But a real commitment to tackling obesity means also getting to grips with the environment in which our children grow up.
But it is important to note the Government is already taking some steps.
However, this personal duty on families must also be matched with Government action at a time when over £500m is being cut from public health grants to local councils.
