Obesity ‘link to same-sex parent’

There is a strong link in obesity between mothers and daughters and fathers and sons, but not across the gender divide, research suggests.

A study of 226 families by Plymouth’s Peninsula Medical School found obese mothers were 10 times more likely to have obese daughters.

The researchers believe the link is behavioural rather than genetic.
They say the findings mean policy on obesity should be re-thought.

Researchers said it was “highly unlikely” that genetics was playing a role in the findings as it would be unusual for them to influence children along gender lines.

Instead, they said it was probably because of some form of “behavioural sympathy” where daughters copied the lifestyles of their mothers and sons their fathers.
It is because of this conclusion that experts believe government policy on tackling obesity should be re-thought.

Much of the focus so far in the UK – in terms of targets and monitoring – has been targeted at younger age groups in the belief that obese children become obese adults.
But the researchers said the assumption ignored the fact that eight in 10 obese adults were not severely overweight when they were children.

In fact, they said their findings suggested the opposite was true – that obese adults led to obese children, the International Journal of Obesity reported.

Study leader Professor Terry Wilkin said: “It is the reverse of what we have thought and this has fundamental implications for policy.

“We should be targeting the parents and that is not something we have really done to date.”
