Objective To investigate the health literacy level among Chongqing residents and its influencing factors.Methods Based on the methods of multi-stage cluster random sampling and probability-proportional-to-size sampling（PPS）

a total of 1 918 Chongqing residents aged 15 to 69 years participated in this survey.A questionnaire was used to investigate the health literacy level of these residents.Results After weighted adjustment

the health literacy level among Chongqing residents in 2015 was 10.16%.The univariate analysis showed that

the health literacy level in urban areas was higher than that in suburb or county areas（P<0.05）;street residents had a higher health literacy level than village or town residents（P<0.05）;a higher educational level was associated with a higher health literacy level（P<0.05）;non-peasant residents had a higher health literacy level than peasants（P<0.05）;and the health literacy level also varied significantly with the annual household income per-capita（P<0.05）.The multiple Logistic regression analysis revealed that

the main factors influencing the health literacy level of Chongqing residents were educational level and annual household income per-capita:residents with junior middle school or above education had a higher health literacy level than illiterate or semi-illiterate residents;residents with an annual household income greater than 5 000～10 000 RMB had a higher health literacy level than those with an annual household income less than 3 000 RMB.Conclusion The influencing factors on the health literacy level among Chongqing residents include educational level and annual household income per-capita.Health education and promotion practitioners should adopt appropriate approaches to provide population-specific health promotion initiatives.
