Heart failure and stroke are rare diagnoses among young people. However, according to a study by the University of Gothenburg, they are now clearly increasing in men under the age of 40. Scientists have discovered an association between obesity in the late teens and weakness.
This study Internal Medicine JournalContains data on 1,258,432 men who served in Sweden between 1971 and 1995 with an average age of 18.3.
Men’s weight, height, Physical fitness Information on enlistment was integrated with data from the National Board of Health and Welfare’s National Patient Registration and Cause of Death Registration from 1991 to 2016. Therefore, men have been monitored for over 20 years since they joined the army.
The percentage of participants who were overweight at the time of enlistment, that is, the percentage of participants with a body mass index (BMI) of 25-30, increased from 6.6% to 11.2% between 1971 and 1995. obesity (BMI over 30) increased from 1.0 to 2.6%. At the same time, the level of physical strength at the time of enlistment also dropped slightly.
Increased heart failure and stroke
“These factors are overweight, obesity, and weakness. heart failure David Avery, an associate professor at the Saar Glenska Academy at Gothenburg University and a specialist at Saar Glenska University Hospital, is the lead author of this study.
“It’s nice to see these young men have a fairly sharp decrease in heart attacks and a reduction in cardiovascular mortality, despite the increase in obesity,” he continues. I will.
Studies show that cases of heart failure within 21 years of enlistment increased by 69%, from 0.49 per 1,000 men enlisted in the first five years (1971-75) to 0.83 / 1,000 enlisted men. Did. The last five (1991–95).
The number of stroke cases (cerebral infarction and cerebral hemorrhage) showed a similar tendency.increase of cerebral infarction From 0.68 in the first five-year cohort to 0.9 per 1,000 people in the last, it was 32%. For cerebral hemorrhage, the increase was 20%, from 0.45 to 0.54 per 1,000.
Strong support for physical activity
In contrast, heart attacks within 21 years of enlistment decreased by 43% from 1.4 to 0.8 per 1,000 people in the first and last enlisted cohorts, respectively. The rate of death from all cardiovascular diseases has also decreased by 50%, from 1.5 to 0.74 per 1,000.
The fact that trends in cardiovascular disease move in different directions over time suggests that other unknown factors are also involved. According to researchers, weight trends after enlistment may be one such factor, but stress and substance use may be other factors. Researchers believe that a sharp decline in smoking underlies the decline, especially in the case of heart attacks. However, the fact remains that overweight and obesity have an impact.
“We see it heart Without the increase in overweight and obesity, the attacks would have been further reduced. Therefore, our results strongly support the belief that obesity and, to some extent, weakness by age 18 affect early-onset cardiovascular disease. Therefore, at the social level, it is important to try more physical activity, not to sit down, and to establish good eating habits already by puberty, “concludes David Åberg.
