Prognostic Factors Tied to Lifestyle in Young Community-Dwelling Stroke Survivors
A Guangzhou cohort compared young and older stroke survivors, finding that lifestyle factors like exercise and social interaction may influence functional outcomes more than age alone.
Stroke incidence among young adults aged 18 to 50 has risen over recent decades, creating a growing population with long post-stroke life expectancy and substantial disability burden. Traditional vascular risk factors do not fully explain this trend, and unhealthy modern lifestyles are increasingly implicated. A recent study enrolled community-dwelling adults from three communities in Guangzhou to identify prognostic factors associated with contemporary lifestyles in young stroke survivors, comparing them with an older cohort.
The study stratified participants into a young adult group (18–49 years) and an older adult group (50 years and older). Baseline questionnaires collected demographic data, education, occupation, medical and family histories, lifestyle factors, and the Essen Stroke Risk Score (ESRS). A one-year telephone follow-up assessed stroke recurrence, modified Rankin Scale (mRS) scores, and changes in ESRS from baseline.
Young adults had higher educational attainment and a distinct occupational distribution. The older group showed more preexisting medical conditions and more frequent family histories of coronary heart disease and cancer. Young participants reported less physical exercise, domestic chores, and social interaction, but better sleep quality and higher rates of cohabitation. In unadjusted analysis, the young group had a lower proportion of favorable functional outcomes (mRS 0–1: 60% vs. 65%), with an odds ratio of 0.789 (95% CI: 0.670–0.930). After adjustment, this disparity attenuated and became non-significant (OR 0.904, 95% CI: 0.730–1.120, p = 0.355). Ischemic stroke recurrence rates were comparable (4% vs. 6%), while the older group showed a more pronounced change in ESRS scores.
The authors conclude that the initially observed disparity in functional outcomes between young and older stroke patients appears heavily influenced by distinct, modifiable lifestyle factors. Early identification and timely intervention against these prognostic factors may help reduce stroke recurrence and long-term sequelae in young adults. However, the study is limited by its community-based design, reliance on self-reported lifestyle data, and one-year follow-up. Findings are observational and do not establish causation.
