Secular trends in rural China demonstrated an increase in first-ever stroke incidence from 124.5 per 100,000 person-years in 1992-1998 to 318.2 in 2006-2012, an annual increase of 6.5% (p<0.05).

Rising stroke incidence signals growing rural burden; extends trends data but leaves causal factors and interventions open.

Stroke incidence in rural China increased rapidly from 1992 to 2012, alongside a significant rise in risk factors such as obesity and high fasting glucose.
Wang et al. (2014) conducted a cohort in Stroke (n=15,438). Time period (2006-2012) vs. Time period (1992-1998) was evaluated on Age-standardized incidence of first-ever stroke per 100,000 person-years (6.5% annual increase, p=< 0.05). Secular trends in rural China demonstrated an increase in first-ever stroke incidence from 124.5 per 100,000 person-years in 1992-1998 to 318.2 in 2006-2012, an annual increase of 6.5% (p<0.05).
