Abstract： Objective To study the temporal trends in gonorrhoea incidence in China between 1991 and 2016.Methods We obtained gonorrhoea surveillance data from the National Center for STD Control and population data from the National Bureau of Statistics in China.Joinpoint regression was performed to assess temporal trends of gonorrhoea incidence stratified by age and gender.Results Male-to-female incidence ratios of gonoeehoea have been increasing during the study period,ranging from 1.60 to 5.08.After the earlier increases,gonorrhoea incidence rates were found to have declined from the early 2000s.However,stalls or reversals of declining trends were observed in sexually active age groups in recent years,particularly a sharp increase (18.5％ per year) among males aged between 15 and 19 years.Conclusions Gonnorrhoea incidence increased sharply from 1991 to 1999 and then declined significantly until 2012.Further observations are needed for slight and nonsignificant increases of incidence in recent years,and more effective interventions targeting adolescents or other high risk populations are needed for disease control and prevention.
