The difference is statistically significant. 1015 people completed the survey of mental health status, the prevalence of depressive symptoms was 8.87%, the monthly income of different families (χ2=13.96, P=0.01), the self-assessed health status (χ2=128.56, P<0.05), the presence or absence of chronic diseases (χ2 =4.78, P=0.03), the difference was statistically significant; the prevalence of anxiety symptoms was 3.84%, different regions (χ2=12.26, P<0.05), occupations (χ2=11.65, P<0.05), household monthly income (χ2=12.65, P=0.01), self-rated health status (χ2=151.11, P<0.05), and chronic diseases (χ2=7.77, P=0.01), the differences were statistically significant; the prevalence of insomnia symptoms was 7.98 % different age (χ2=18.45, P<0.05), region (χ2=5.11, P=0.02), monthly household income (χ2=12.68 P=0.01), self-assessed health status (χ2=91.71, P<0.05), There was a statistically significant difference between those with or without chronic diseases (χ2=33.25, P<0.05); 557 elderly people over 65 years old completed the cognitive dysfunction screening, the prevalence of cognitive dysfunction was 17.41%, and the different self-assessed health status (χ2=96.24, P<0.05) and with or without chronic diseases (χ2=107.09, P<0.05), the difference was statistically significant. Conclusion The mental health literacy and status of residents has not improved significantly during the second outbreak of the epidemic, indicating that under the normalization of epidemic prevention and control, more attention should be paid to the mental health of residents, and targeted health education and psychological intervention should be carried out to avoid relative adverse events.
