Recent data on the incidence and trends for recurrent strokes in China are scarce. We assessed the temporal trends in recurrent stroke incidence using in rural China. The age-standardized incidences of recurrent stroke, within 5 years of the incident stroke event, were estimated for 3 time periods: 1992–1998, 1999–2005, and 2006–2012. Among the 768 documented incident stroke cases, 26.3% of the patients experienced recurrent stroke within 5 years. The overall age-adjusted recurrent stroke incidence was 43.93 per 100,000 person-years (1992–2012). During the 2006–2012 period, the recurrent stroke incidence per 100,000 person-years was 107.79 in men, and 557.76 in individuals ≥65 years old. There were significant upward tendencies observed in this population across sex, age, or type of stroke (except for among individuals ≥65 years old with incident intracerebral hemorrhages). Compared with the recurrent stroke incidence observed in the 1992–1998 period, that observed during the 2006–2012 period was more than 3-fold higher; the greatest increase (6.8-fold) was observed in women. These findings suggest an urgent need to improve risk factor management and implement appropriate medical resources to contain this upward trend in recurrent stroke incidence and reduce the overall stroke burden in China.
