Background: With smartphone use widespread worldwide, smartphone addiction is an emerging epidemic. This study aims to investigate the prevalence of smartphone addiction among freshmen medical students and to explore its association with personal factors, mental health, and professional identity. Methods: This cross-sectional study was conducted from October 10th to November 10th, 2020 and included 2,182 first-year college students at Wannan Medical College, China. The smartphone addiction test, professional identity, and a 12-item general health questionnaire were used for this cross-sectional survey. Pearson’s correlation coefficient (r) was employed to examine the correlations between smartphone addiction and mental health and professional identity. Binary logistic regression analysis was carried out to assess the factors influencing smartphone addiction. Of the 2,182 students, 866 (39.7%) were identified as having smartphone addiction. The logistic regression analysis shows that four factors (professional identity scale, poor mental health, smartphone use before sleep, and perceived study pressure) were significantly associated with smartphone addiction. Conclusions: This cross-sectional study suggests that smartphone addiction is common among Chinese freshmen medical students. Smartphone addiction was common among the freshmen medical students surveyed. The findings imply that promotional programs, aimed at enhancing mental health and professional identity among freshmen medical students, help to reduce smartphone addiction in this population.

Objective: This study aimed to assess Chinese medical students’ smartphone addiction and its effects on subhealth and insomnia. Methods: A cross-sectional survey was conducted from October 14, 2020 to November 14, 2020 by administering an online questionnaire to Wannan Medical College students. Results: Of 2741 students who completed the survey, 1,447 (52.8%) had smartphone addiction. Medical specialty (p = 0.004), alcohol consumption (p = 0.001), smartphone use in bed (p = 0.000), depression (p = 0.000) and anxiety (p = 0.000) were strongly associated with smartphone addiction. The impacts of smartphone addiction on subhealth (p = 0.000) and insomnia (p = 0.000) were significant. Conclusion: This survey shows that the smartphone addiction detection rate among medical students was 52.8%. Students who did not like their medical specialty, consumed alcohol, used their smartphones in bed, and suffered from depression and anxiety had a higher smartphone addiction detection rate. The subhealth and insomnia of medical students are adversely associated with smartphone addiction.

This study aimed to investigate the suboptimal health status or subhealth status and their relationship with mental health and smartphone addiction among Chinese medical students. A cross-sectional survey was conducted at Wannan Medical College of China in Wuhu. A total of 2,741 students were surveyed in October 2020. Of 2,741 Chinese medical students who completed the survey, 904 (33%) participants reported to have had subhealth status. Anxiety status (p<0.001), depression status (p<0.001), and smartphone addiction status (p<0.001) have strong association with subhealth status. This survey shows that the detection rate of subhealth status in Chinese medical students was 33%. Anxiety, depression, and smartphone addiction students had a higher detection rate of subhealth status. The anxiety, depression, and smartphone addiction of Chinese medical students are associated with subhealth status.

Background: With the acceleration of population aging, depressive symptoms in older adults have become an urgent global public health issue. It is critical to understand how to prevent and intervene the epidemic of depressive symptoms. Several studies have reported the prevalence of depressive symptoms among older adults in urban and rural China, but there is a lack of cross-sectional studies on the prevalence of depressive symptoms among older adults in Anhui Province after the COVID-19 pandemic.Methods: Between December 2023 and February 2024, we used convenience sampling to randomly recruit 1,175 older people over 60 years old in Anhui Province, China. The PHQ-9 depressive symptom scale, frailty scale, and social frailty scale were used in the study. Logistic regression was used to analyze the association between frailty, social frailty, family health and depressive symptoms in older adults.Result: Of the 1,175 participants, 406 (34.6%) had depressive symptoms. Binary logistic regression results showed that Status of body pain (p < 0.001), Number of hospitalizations in the past year (p < 0.001), Status of social frailty (p < 0.001) and Status of frailty (p < 0.001) were highly correlated with depressive symptoms in older adults. While family health (OR = 0.53, 95% CI = 0.26–1.11, p = 0.092) was a protective factor for depressive symptoms in older adults.Conclusion: The prevalence of depressive symptoms among older adults is high in Anhui Province, China. Frailty, social frailty, and poor family health are associated with higher prevalence of depressive symptoms in older adults. Public health departments should pay more attention to the construction of mental health protection in the three environmental contexts of individual, family and society to promote healthy aging.

This study aimed to assess the attitudes of Chinese residents toward COVID-19 vaccines and explore the potential drivers for Chinese residents' vaccine hesitancy. A cross-sectional survey was conducted from February 16 to March 16, 2021, by administering an online questionnaire to the Chinese residents. Of 5240 residents who completed the survey, 464 (8.9%) participants reported to have had one shot, and 348 (6.6%) reported to have had 2 shots. At the time the questionnaire was administered, 2298 (43.9%) participants reported they wanted to get vaccinated, while 2255 (43.0%) declared that they still did not know, and 687 (13.1%) respondents declared vaccine refusal. Overall, 2255 (43%) participants were categorized as vaccine hesitancy. Female participants (p=0.000), <20 years old (p=0.000), have low risk of COVID-19 (p=0.000) infection and strong associations of vaccine hesitancy. eHealth literacy was a protective factor. The results of this study show high rates of vaccine hesitancy in China. This could pose a serious threat to the preventive measures that aimed at controlling COVID-19 spread in the country. The government and different media platforms should encourage the dissemination of correct information about vaccines, the communities and medical staff to improve residents' knowledge about vaccines, and strive to improve residents' electronic health literacy.

Background: Over the past three years, the COVID-19 pandemic has brought an overwhelming impact on China’s hospital system and health care workers, which can lead to post traumatic stress disorder (PTSD) symptoms. Previous research has shown that the COVID-19 pandemic had long-term adverse effects on the mental health of health care workers. Indeed, PTSD symptoms have emerged as one of the significant mental health issues for health care workers arising from the COVID-19 pandemic. Therefore, we conducted this cross-sectional survey to investigate the prevalence of PTSD symptoms in health care workers and its relationship with the fear of COVID-19 and the COVID-19 burden after the full liberalization of COVID-19 prevention and control policy in China. Methods: This study was conducted three years after the global COVID-19 pandemic (January 15 to January 16, 2023). This study was conducted via the Wenjuanxing platform and used the Chinese versions of the scales PC-PTSD-5, COVID-19 Anxiety Scale (FCV-19S), Social Support Scale, COVID-19 Stress Scale, GAD-2, and PHQ-2. Results: The prevalence of PTSD symptoms in health care workers was 24.3% (232/955). depression(P < 0.001), anxiety(P < 0.05), the fear of COVID-19(P < 0.001), and COVID-19 burden(P < 0.001) were highly correlated with PTSD symptoms in health care workers. Social support(P < 0.05) was a protective factor of PTSD symptoms. Conclusions: This survey shows that PTSD symptoms were highly prevalent among Chinese health care workers after the COVID-19 pandemic. Governments and leaders of medical institutions should, through psychological interventions, address the current situation of PTSD symptoms among health care workers and develop targeted programs and strategies to reduce their psychological problems.
