Healthy 20s, Healthy 40s

Maintaining a healthy lifestyle from young adulthood into your 40s is strongly associated with low cardiovascular disease risk in middle age, according to a new study in journal Circulation.

According to the study's authors, even people with a family history of heart problems were able to have a low cardiovascular disease risk profile if they started living a healthy lifestyle when they were young. This supports the notion that lifestyle may play just as prominent a role as genetics.

This is the first study to show the association of a healthy lifestyle maintained throughout young adulthood and middle age with low cardiovascular disease risk in middle age. The majority of people who maintained five healthy lifestyle factors from young adulthood (including a lean body mass index (BMI), no excess alcohol intake, no smoking, a healthy diet and regular physical activity) were able to remain in this low-risk category in their middle-aged years.

In the first year of the study, when the participants' average age was 24 years old, nearly 44 percent had a low cardiovascular disease risk profile. Twenty years later, overall, only 24.5 percent fell into the category of a low cardiovascular disease risk profile. Sixty percent of those who maintained all five healthy lifestyles reached middle age with the low cardiovascular risk profile, compared with fewer than 5 percent who followed none of the healthy lifestyles.

Bonnie: This is how a preventive study should be structured. Twenty years is the ideal time to gauge the impact of optimal lifestyle adherence. The fact that the study started in young people was key.
