LONDON — Authorities are considering taking an eight-year-old boy who weighs 218 pounds into protective custody unless his mother improves his diet, officials said yesterday.Social service officials will meet with family members today to discuss the health of Connor McCreaddie, who weighs more than three times the average for his age.

“The worst case would be Connor getting taken into care. He is well cared for,” the boy’s mother, Nicola McKeown, told ITV television.

A spokeswoman for health officials in Wallsend, North Tyneside, 300 miles north of London, said the hearing was part of a process that could eventually lead to Connor being taken into protective care. She declined to comment further.

The health agencies organising the meeting said they “have been working with the family over a prolonged period of time and will continue to do so.”

Officials would not say whether Connor suffered from a medical condition that led to his obesity, citing privacy issues.

An unidentified health official was quoted as telling The Sunday Times that taking custody of Connor would be a last resort, but said the family had repeatedly failed to attend appointments with nurses, nutritionists and social workers.

“Child abuse is not just about hitting your children or sexually abusing them, it is also about neglect,” the official was quoted as saying.

Dr. Colin Waine, the director of the National Obesity Forum in Nottingham, England, called Connor’s lifestyle “extremely dangerous,” adding he is at risk of developing diabetes in his early teens, and cardiovascular and nervous system problems in his 20s.

“He’s really at risk of dying by the time he’s 30,” Waine said.

Dr. Michael Markiewicz, a pediatrician, agreed.

“I’m not saying they can’t care for him, but what they are doing is through the way they are treating him and feeding him, they are slowly killing him,” he said.

Connor’s case attracted national attention after his mother allowed an ITV News crew to film his day-to-day life over the course of a month.

Connor’s mother said he steals and hides food, frustrating her efforts to help him. He eats double or triple what a normal seven-year-old would have, she said.

“If I didn’t give him enough at teatime then he would just go on at us all night for snacks and stuff,” she told ITV.
