Grandparents help grandkids in many ways—but the reverse may be true too, U-M poll suggests

Less loneliness, better mental health seen in those who visit, care for grandchildren often

As many Americans prepare to gather with their families for the holidays, a new University of Michigan poll shows the importance of grandchildren in grandparents' lives.

The poll shows that having grandkids and seeing them regularly may have a link to older adults' mental health and risk of loneliness. Although the poll can't show cause and effect, the findings suggest a need to study the role of grandparenting in older adults' lives as part of a broader effort to address social isolation.

At the same time, the poll found that many grandparents support their grandchildren under 18 in some way, from covering major expenses to providing child care or babysitting regularly, or even daily.

The data come from the National Poll on Healthy Aging, based at the University of Michigan's Institute for Healthcare Policy and Innovation. The poll is supported by AARP and Michigan Medicine, U-M's academic medical center.

In all, the poll shows, 60% of adults aged 50 and over have at least one grandchild, including step-grandchildren, adopted grandchildren and great-grandchildren. That includes the 27% who said they have five or more grandkids. Those over age 65 were much more likely than those in their 50s and early 60s to say they have one or more grandchildren, at 76% vs. 46%.

People with at least one grandchild were more likely than those without grandkids to say they hardly ever feel isolated. In all, 72% of those with grandchildren say they hardly ever feel isolated compared with 62% of those without grandchildren. People without grandkids were also more likely to say their mental health is fair or poor compared with those who have grandchildren, 13% versus 9%.

"For many older people, becoming a grandparent is a major milestone in their lives. Our findings show there are many dimensions to grandparenting, and possible positive effects of grandparenting, some of which may not be widely recognized," said Kate Bauer, associate professor of nutritional sciences at the U-M School of Public Health who worked with the poll team.

"With growing attention by policymakers to the role of social interaction in the well-being of people over age 50, and also the struggles of older adults who are raising children under 18, we hope our findings will inform those policy discussions."

Poll director Jeffrey Kullgren, U-M associate professor of internal medicine and a physician at the VA Ann Arbor Healthcare System, said health care providers should consider asking their older patients whether they are active in their grandchildren's lives and encourage more involvement among those who are struggling with loneliness or depression.

Caring for children

Nearly half, or 49%, of those with grandchildren under age 18 provide care for them at least once every few months. In all, 20% of those with grandkids under 18 care for one or more at least once a week, with 8% providing daily or near-daily care. Ten percent of grandparents aged 50 to 64 reported providing daily or near-daily care, compared with 6% of those 65 and older.

Older adults who identified as Hispanic were more likely to say they take care of a grandchild under 18 every day or nearly so-15% compared with 7% of non-Hispanic white and 9% of non-Hispanic Black older adults who have grandchildren under age 18. With the high cost and limited availability of childcare in the U.S., grandparents who provide regular care for their grandkids are giving their families a valuable resource, Bauer notes.

Seeing grandchildren

The poll asked older adults who have grandkids under age 18 how often they see them. In all, 18% of grandparents see their grandchild or grandchildren every day or nearly every day, an additional 23% see them at least once a week and 23% see them once or twice a month, while 36% said they only see them every few months or less.

In general, grandparents who see their grandkids more often were less likely to say they feel isolated. Overall, 78% of those who see grandchildren under 18 every day or nearly every day said they hardly ever feel isolated, compared with 65% of those who see them every few months or less. Also, 73% of those who see their grandchildren at least weekly or once or twice a month said they hardly ever feel isolated.

There was a similar trend when the poll team looked at those who reported hardly ever feeling a lack of companionship. In all, 57% of grandparents who see their grandkids only every few months reported feeling this way, compared with around 70% of those who see them more frequently.

Those grandparents who see their grandchildren only every few months or less were more likely to say their mental health is fair or poor, 13%, compared with those who see them at least once a week, 4%, or once or twice a month, 8%. There was no difference for physical health status.

Eating with or cooking with grandchildren

Bauer's research focuses on social factors related to children's eating behaviors and weight. The poll asked older adults who have grandchildren ages 1 to 17 whether they had engaged in food-related activities with their grandchildren in the past month.

In all, 61% of these older adults said they had shared at least one meal with a grandchild or grandchildren in the past month, and 47% said they had prepared food for them, while an equal percentage said they had bought food for their grandkids. And a sizable percentage, 36%, said they had baked or cooked with their grandchildren in the past month.

"Eating, and especially cooking, with grandchildren can be an opportunity for older adults to make important social and cultural connections, such as passing down knowledge and recipes," Bauer said. "Given how many grandparents are frequently engaging with their grandchildren around food and eating, it is important that they relay positive and healthy messages about nutrition and body size."

Paying for grandchildren's expenses

Overall, nearly one-third, or 32%, of older adults who have grandchildren under age 18 say they have helped provide financial support to them in some way in the past year.
This includes 23% who helped with day-to-day expenses such as clothes, meals and groceries; 10% who paid for educational expenses; and 10% who provided support for other big expenses such as summer camps, sports and day care.

Living with grandchildren

Among all adults aged 50 and older who have grandchildren, 6% live in the same home as at least one of their grandchildren. This percentage was higher among Black older adults (9%) and Hispanic older adults (9%) compared with white older adults (5%), and among older adults in their 50s and early 60s (8%) compared with those over age 65 (4%).

Also, among those who have grandchildren, 3% said they have primary custody or primary parental responsibility of a grandchild aged 17 and younger. The percentage was higher (6%) among grandparents who are aged 50 to 64, compared to those 65 and older (1%).

Bauer notes the grandparents who take on full-time roles caring for grandchildren-forming what are sometimes called "grandfamilies"-can play a critical role in providing stability during challenging times in children's lives. More research is needed on their role.

Michigan findings

Thanks to funding from the Michigan Health Endowment Fund, the poll team was also able to look at grandparenting among 1,174 Michigan residents aged 50 and over. In all, 63% of Michiganders in this age group have at least one grandchild, including 51% of those in their 50s and early 60s and 74% of those 65 and older.

Older adults living in northern, central and southwestern Michigan were more likely to be grandparents than those in the southeastern part of the state.

When it came to providing daily or nearly daily care for grandkids under age 18, Michiganders reported doing so at about the same percentages as those in the rest of the country. But 25% of older Black Michigan residents said they provide daily or near-daily care to a grandchild or grandchildren, higher than the national percentage, while the rate of daily or near-daily grandchild care among white Michiganders was around 6%, similar to the national figure.

In addition, 30% of Black Michigan grandparents said they see their grandchildren every day or nearly every day compared with 15% of white Michigan grandparents. Also, older Michigan women were more likely to say they see their grandchildren every day or nearly every day compared with men (21% vs. 11%).

Grandparents living in the southeastern region were more likely to be part of 'grandfamilies' by having custody of at least one grandchild, with 5% saying they do, compared with 3% or less elsewhere in the state.

The poll findings come from a nationally representative survey conducted by NORC at the University of Chicago for IHPI and administered online and via phone in August 2024 among 3,486 adults aged 50-94 across the United States. The Michigan sample included 1,174 respondents aged 50-94. The samples were subsequently weighted to reflect the U.S. and Michigan populations.
