New cancer danger identified – Grandma and Grandpa
Grandparents may be contributing to their grandchildren’s long-term risk of cancer by spoiling them with sweets, say researchers.
Grandparents are a potential health hazard for children and may even increase their risk of cancer, say scientists.
They spoil their grandchildren with sweet “treats” and big helpings of fattening food, and expose their young lungs to second-hand tobacco smoke, it is alleged.
The extraordinary claims are based on a review of research into the influence grandparents have on lifestyle factors that can sow the seeds of cancer in later life.
Lead author Dr Stephanie Chambers, from the University of Glasgow’s Public Health Sciences Unit, said: “While the results of this review are clear that behaviour such as exposure to smoking and regularly treating children increases cancer risks as children grow into adulthood, it is also clear from the evidence that these risks are unintentional.
“Currently grandparents are not the focus of public health messaging targeted at parents and in light of the evidence from this study, perhaps this is something that needs to change given the prominent role grandparents play in the lives of children.”
Previous research has looked at the way parents can affect their children’s susceptibility to cancer and other diseases, but less attention has been paid to the role of part-time carers such as grandparents, said the scientists
The Glasgow team analysed data from 56 studies from 18 countries that included information about the influence of grandparents on their grandchildren.
Overall, grandparents were found to have an adverse effect – despite meaning well. In many cases, such as rewarding good behaviour with sweets, they were putting the health of their grandchildren at risk with kindness.
Smoking, poor diet, excess weight and lack of physical activity are all known to increase the risk of cancer, said the researchers.
Factors associated with long-term cancer risk were first experienced within the family setting.
Social trends, such as the growing proportion of women in the workforce, rising childcare costs, and increasing numbers of single parents, had meant that more children were being placed in the care of their grandparents.
The research found that “excessive feeding” of children was a significant grandparent problem, as was providing meals that may be made from scratch but with unhealthy ingredients.
There was also evidence that the poverty and hunger some grandparents experienced themselves as children led them to believe extra weight was a sign of good health.
Grandparents smoking in the home was identified as having a negative impact, both by setting a bad example and exposing children to second hand tobacco smoke.
The research found no significant evidence of grandparents influencing alcohol consumption or sun exposure.
To some extent, the negative impact on diet and weight was balanced by a more positive finding with respect to physical activity, the scientists found.
None of the reviewed studies took account of the positive emotional benefit of children spending time with their grandparents, the authors pointed out.
Dr Chambers added: “From the studies we looked at, it appears that parents often find it difficult to discuss the issues of passive smoking and over-treating grandchildren.
“Given that many parents now rely on grandparents for care, the mixed messages about health that children might be getting is perhaps an important discussion that needs to be had.”
The findings are published in the online journal Public Library of Science ONE.
Professor Linda Bauld, from the charity Cancer Research UK which co-funded the study, said: “Children’s health can be affected by range of factors, and this study reinforces the importance of the broader family picture.
“Children should never be exposed to second hand smoke. But it’s also important for children to maintain a healthy weight into adulthood, and in today’s busy world it’s often the wider family who have a role to play in keeping youngsters healthy. If healthy habits begin early in life, it’s much easier to continue them as an adult.”
Tam Fry, chairman of the National Obesity Forum, said: “Finding a doting grandparent who is confident enough to follow rules laid down by mum and to the letter is frequently a rarity.
“Both nan and grandpa can leave themselves wide open to manipulative and increasingly savvy grandchildren in their desire to please the little darlings.
“They bring out the biscuits at the slightest hint of a tantrum and, as the researchers report, they are also often too protective in loco parentis.
“The thought of losing children when out in the park may result in the kids being under house arrest – sweeties on demand and woefully short on exercise.
“Unfortunately, despite the researchers’ suggested messaging, it may ever be so, as parents increasingly need to rely on this free form of childminding.”
