A child once approached me, hunched over, carrying a vacuum cleaner like a walking stick. In a wobbly voice, he asked: “Do you want to play grannies?”

The idea came from the children’s TV show Bluey, which  has  episodes,  a book,  magazine  editions and an  image filter  about dressing up as “grannies”.

Children are also dressing up as 100-year-olds to mark their first “100 days of school”, an idea  gaining popularity  in Australia.

Is this all just harmless fun?

How stereotypes take hold

When I look at the older people in my life, or the patients I see as a geriatrician, I cannot imagine how to suck out the individual to formulate a “look”.

But Google “older person dress-ups” and you will find  Pinterests  and  Wikihow pages  doing just that.

Waistcoats, walking sticks, glasses and hunched backs are the key. If you’re a “granny”, don’t forget a  shawl and tinned beans. You can buy “old lady”  wigs  or an “old man”  moustache and bushy eyebrows.

This depiction of how older people look and behave is a stereotype. And if dressing up as an older person is an example, such stereotypes are all around us.

What’s the harm?

There is  some debate  about whether stereotyping is intrinsically wrong, and if it is, why. But there is plenty of research about the harms of  age  stereotypes or ageism. That’s harm to current older people and harm to future older people.

The World Health Organization  defines ageism  as: “the stereotypes (how we think), prejudice (how we feel) and discrimination (how we act) towards others or ourselves based on age.”

Ageism  contributes to  social isolation, reduced health and life expectancy and costs economies  billions of dollars  globally.

When it comes to health, the impact of negative stereotypes and beliefs about ageing may be even  more harmful  than the discrimination itself.

In laboratory studies, older people perform  worse  than expected on tasks such as memory or thinking after being shown negative stereotypes about ageing. This may be due to a “stereotype threat”. This is when a person’s performance is impaired because they are worried about confirming a negative stereotype about the group they belong to. In other words, they perform less well because they’re worried about acting “old”.

Another theory is “stereotype embodiment”. This is where people absorb negative stereotypes throughout their life and come to believe decline is an inevitable consequence of ageing. This leads to biological, psychological and physiological changes that  create  a self-fulfilling prophecy.

I have seen this in my clinic with people who do well, until they realise they’re an older person – a birthday, a fall, a revelation when they look in the mirror. Then, they stop going out, stop exercising, stop seeing their friends.

Evidence for “stereotype embodiment” comes from studies that show people with more negative views about ageing are more likely to have higher levels of stress hormones (such as cortisol and C-reactive protein) and are  less likely  to engage in health behaviours, such as exercising and eating healthy foods.

Younger adults with negative views about ageing are  more likely  to have a heart attack up to about 40 years later. People with the most negative attitudes towards ageing have a lower life expectancy by as much as  7.5 years.

Children are particularly susceptible to absorbing stereotypes, a process  that starts  in early childhood.

Ageism is all around us

One in two people  have ageist views, so tackling ageism is complicated given it is socially acceptable and normalised.

Think of all the birthday cards and jokes about ageing or phrases like “geezer” and “old duck”. Assuming a person (including yourself) is “too old” for something. Older people say it is harder to  find work  and they face discrimination in  health care.

How can we reduce ageism?

We can reduce ageism through laws, policies and education. But we can also reduce it via  intergenerational contact, where older people and younger people come together. This helps break down the segregation that allows stereotypes to fester. Think of the TV series  Old People’s Home for 4 Year Olds  or the follow-up  Old People’s Home for Teenagers. More simply, children can hang out with their older relatives, neighbours and friends.

We can also challenge a negative view of ageing. What if we allowed kids to imagine their lives as grandparents and 100-year-olds as freely as they view their current selves? What would be the harm in that?The Conversation
