An analysis of more than five decades of health data on 10,000 adults revealed that close to 5% experienced a stroke during the follow-up period, with the risk for ischemic stroke being more than twice as high in women who had obesity as teens or young adults. The risk was even higher for hemorrhagic stroke in both men and women with a history of obesity in youth.
“Our findings suggest that being overweight may have long-term health effects, even if the excess weight is temporary,” lead author Ursula Mikkola, BM, an investigator in the Research Unit of Population Health at the University of Oulu, Oulu, Finland, said in a news release.
“Health care professionals should pay attention to overweight and obesity in young people and work with them to develop healthier eating patterns and physical activity — however, conversations with teens and young adults about weight should be approached in a nonjudgmental and nonstigmatizing manner,” she added.
The study was published online in Stroke.
Gender Differences
Childhood obesity has been associated with a heightened risk for cerebrovascular disease later in life, but most studies have focused on body mass index (BMI) at a single time point without considering its fluctuations throughout life, the investigators noted.
For the study, investigators used data from the Northern Finland Birth Cohort 1966, a prospective, general population-based birth cohort that followed 10,491 individuals (5185 women) until 2020 or the first stroke, death, or moving abroad, whichever came first.
Mean (SD) follow-up for each participant was 39 years from age 14 onward and 23 years from age 31 onward. The analysis was conducted between 1980 and 2020.
BMI data were collected from participants at the age of 14 and 31 years. Age 14 covariates included smoking, parental socioeconomic status, and age at menarche (for girls). Age 31 covariates included smoking and participants’ educational level.
During the follow-up period, 4.7% of participants experienced stroke. Of these events, 31% were ischemic strokes and 40% were transient ischemic attacks. The remainder were hemorrhagic or other cerebrovascular events.
Using normal weight as a reference, researchers found that the risk for ischemic stroke was over twice as high for women who had been overweight at ages 14 (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.44-4.31) and 31 (HR, 2.13; 95% CI, 1.14-3.97) years. The risk was also considerably higher for women who had obesity at ages 14 (HR, 1.87; 95% CI, 0.76-4.58) and 31 (HR, 2.67; 95% CI, 1.26-5.65) years.
The risk for hemorrhagic stroke was even higher, both among women (HR, 3.49; 95% CI, 1.13-10.7) and men (HR, 5.75; 95% CI, 1.43-23.1) who had obesity at age 31.
No similar associations were found among men, and the findings were independent of earlier or later BMI.
The risk for any cerebrovascular disease related to overweight at age 14 was twice as high among girls vs boys (HR, 2.09; 95% CI, 1.06-4.15), and the risk for ischemic stroke related to obesity at age 31 was nearly seven times higher among women vs men (HR, 6.96; 95% CI, 1.36-35.7).
“Stroke at a young age is rare, so the difference of just a few strokes could have an outsized impact on the risk estimates,” the study authors said. “Also, BMI relies solely on a person’s height and weight; therefore, a high BMI may be a misleading way to define obesity, especially in muscular people who may carry little fat even while weighing more.”
Caveats
In an accompanying editorial, Larry Goldstein, MD, chair of the Department of Neurology, University of Kentucky, Lexington, Kentucky, and codirector of the Kentucky Neuroscience Institute, said the study “provides additional evidence of an association between overweight/obesity and stroke in young adults.”
However, Dr. Goldstein added that “while it is tempting to assume that reductions in overweight/obesity in younger populations would translate to lower stroke rates in young adults, this remains to be proven.”
Moreover, it is “always important to acknowledge that associations found in observational studies may not reflect causality.”
This study was supported by Orion Research Foundation, Päivikki and Sakari Sohlberg Foundation, and Paulo Foundation. Dr. Mikkola reported no relevant financial relationships. The other authors’ disclosures are listed on the original paper. Dr. Goldstein reported no relevant financial relationships.
