How Obesity Can Be Inherited From Parents
- A recent study highlights a notable trend: children of parents who experienced obesity in midlife are substantially more prone to obesity themselves at the same age.
- This research meticulously tracked two generations of families, aiming to unravel the transmission of obesity from one generation to the next.
- Despite these findings, the precise mechanisms underlying this intergenerational transmission of obesity remain inadequately understood.
New research from Norway looks into how obesity might be passed from parents to their kids. At an upcoming event called the European Congress on Obesity, scientists will share their findings that kids whose parents were obese around middle age are more likely to be obese at that age, too.
The study also showed that the body mass index (BMI), which is a way to measure body fat based on height and weight, of parents can affect their children's BMI in similar ways.
One of the researchers explained that if one or both parents were obese in middle age, their kids had a much higher chance of being obese at the same age.
An expert in the field, who wasn't part of this study, mentioned that this research builds on what we already know about obesity and how our genes might influence it.
Past studies have linked parents and their kids to obesity, but this new study specifically looks at how this link appears in middle age. The full details of this research have yet to be published in a scientific journal.
Children, Parents, And Obesity
In their study, the researchers found that kids whose parents were obese in their middle years were six times more likely to be obese at the same age compared to kids whose parents had a healthy weight.
Even if just one parent was obese, the risk for the kids was still three times higher than if neither parent was obese. The risk varied a little depending on which parent was obese: kids were more likely to be obese if their dad was obese compared to if their mom was.
They also discovered a clear link between how much body fat parents have, measured by BMI, and their kids' BMI. For example, if a mom's BMI increased by four points, her kids' BMI increased by about .8 points. And for dads, a rise of 3.1 in their BMI meant their kids' BMI went up by .74 points.
The researcher mentioned that while we've seen this connection between parents' and kids' BMI before, even in teenagers, only a few studies have looked at it in middle-aged adults.
Multi-Generational Obesity
In Norway, there's a study called the Tromsø study that tracks health information from many people. This study has been ongoing and collects data from different families across generations.
Researchers looked at information from over 2,000 families, focusing on parents and their children in middle age, between 40 to 59 years old. The parents participated in the study in the mid-90s, and their children joined about 20 years later, around 2015 and 2016.
When the scientists analyzed the data, they considered other factors that could affect the results, like the people's age, whether they were male or female, their education, and their activity level.
They found something interesting but only partially surprising. Parents and their kids' body mass indexes (BMI) – a way to measure if someone is a healthy weight for their height – were often similar. Especially if both parents were overweight, their children were more likely to be overweight during their teenage years, too.
Another study in Norway examinedund a similar link between parents' and children's BMI, especially during the children's more than 8,000 families and fo teenage years.
However, these studies need to find out exactly why this happens. They can see the pattern, but they need help explaining its reasons. Obesity, or being very overweight, is a complicated thing. It can be passed down through families, but it's not just about genes. The environment you live in, like what kind of food is available, how much you move, stress, and other factors also play a big role.
So, obesity is considered a "multifactorial disease," which means it doesn't just have one cause. It results from many different factors working together, including our genes and the world around us.
Health Risks and Economic Impact of Obesity
Obesity is a significant health issue all around the world.
In Europe, the situation is serious, too. A lot of adults are dealing with obesity. Over the years, the number of people who are obese has been going up. This isn't just a tiny increase; we're seeing a lot more cases of severe obesity as well.
Being obese can lead to many other health problems. Some of these include:
- High blood pressure
- Type 2 diabetes
- Strokes
- Anxiety and depression
- Heart disease
Because obesity can cause so many other health issues, it ends up costing a lot of money for healthcare. In Europe, the amount of money spent on dealing with obesity and its related health problems is enormous, running into billions of euros every year.
