Mahjong Playing and Leisure Physical Activity Alleviate Cognitive Symptoms in Older Community Residents.

Leisure activities, particularly physically and cognitively stimulating leisure activities, mitigate cognitive decline. The present study aimed to examine the relationship between mahjong playing, leisure physical activity, and mild cognitive impairment (MCI). Older adults with and without MCI were recruited (n = 489, healthy group; and n = 187, MCI group). The regression results showed that years of mahjong playing (odds ratio = 0.595, 95% confidence interval [0.376, 0.961], p = .032) and physical activity (odds ratio = 0.572, 95% confidence interval [0.381, 0.849], p = .012) were associated with reduced odds of having MCI after adjusting for a series of covariates. Leisure physical activity and mahjong playing interacted with each other and produced combined effects on the odds of having MCI. Combined cognitive and physical interventions may produce larger benefits on cognition than either intervention alone.

Changes in the Incidence of Retinopathy of Prematurity in Extremely Low Birth Weight Infants in South China From 2004 to 2018.

PURPOSE: To report the changes in incidence and risk factors of retinopathy of prematurity (ROP) in extremely low birth weight (ELBW) infants over a 15-year period in South China. METHODS: The medical records of ELBW infants were retrospectively reviewed through established database of Shenzhen Screening for ROP Cooperative Group. The incidence and severity of ROP were compared among three successive 5-year periods (P1: 2004-2008, P2: 2009-2013, P3: 2014-2018). Gestational age, birth weight, plurality, mode of delivery and gender were analyzed as risk factors for ROP in ELBW infants. RESULTS: Among the 1099 included ELBW infants, 557 (50.7%) had ROP, and 328 (29.9%) had severe ROP. The highest incidence of ROP (87.5%) and severe ROP (82.5%) were seen in P1. From P2 to P3, the incidence of ROP and severe ROP increased from 45.9% to 50.3% for ROP (P < .05) and from 26.4% to 28.3% for severe ROP (P < .05), respectively. Multivariate logistic regression analysis found only gestational age has a significant effect on the incidence of ROP and severe ROP. CONCLUSIONS: From 2004 to 2018, the incidence of ROP and severe ROP in ELBW infants in South China was 50.7% and 29.9%, respectively. Controlling for the other risk factors, only gestational age was statistically associated with ROP in ELBW infants.

COMPARISON OF INTRAVITREAL INJECTION OF RANIBIZUMAB VERSUS LASER THERAPY FOR ZONE II TREATMENT-REQUIRING RETINOPATHY OF PREMATURITY.

PURPOSE: To compare the efficacy of intravitreal injection of ranibizumab (IVR) monotherapy and laser therapy for treatment-requiring retinopathy of prematurity (ROP) in Zone II. METHODS: A prospective, randomized, controlled single-center trial was applied from January 2014 to December 2014; infants who were diagnosed as Zone II treatment-requiring ROP (i.e., Zone II Stage 2 or 3 ROP with plus disease) were randomly assigned to receive IVR monotherapy or laser therapy, and the follow-up interval was at least 6 months. Any eyes that developed recurrence of ROP underwent crossover re-treatment. RESULTS: A total of 100 eyes of 50 ethnic Han Chinese infants were enrolled. At the last follow-up, 26 eyes of 13 infants developed recurrence of ROP in the IVR group and 2 eyes of 1 infant developed recurrence of ROP in the laser therapy group. There was a significant statistical difference in the rate of ROP recurrence between IVR and laser therapy to treat Zone II treatment-requiring ROP (P = 0.001). CONCLUSION: Although IVR appears to regress ROP to certain levels and continue to promote the vascularization of peripheral retinal vessels, a substantial proportion of infants developed recurrence of ROP after a single-dose IVR. Therefore, IVR is not recommended as a single-dose monotherapy for Zone II treatment-requiring ROP.

Cell phone-based health education messaging improves health literacy.

BACKGROUND: The ubiquity of cell phones, which allow for short message service (SMS), provides new and innovative opportunities for disease prevention and health education. OBJECTIVE: To explore the use of cell phone-based health education SMS to improve the health literacy of community residents in China. METHODS: A multi-stage random sampling method was used to select representative study communities and participants ≥ 18 years old. Intervention participants were sent health education SMSs once a week for 1 year and controls were sent conventional, basic health education measures. Health literacy levels of the residents before and after the intervention were evaluated between intervention and control groups. RESULTS: Public health literacy scores increased 1.5 points, from 61.8 to 63.3, after SMS intervention for 1 year (P<0.01); the increase was greater for males than females (2.01 vs. 1.03; P<0.01) and for Shenzhen local residents than non-permanent residents (2.56 vs. 1.14; P<0.01). The frequency of high health literacy scores was greater for the intervention than control group (22.03% to 30.93% vs. 22.07% to 20.82%). With health literacy as a cost-effective index, the cost-effectiveness per intervention was 0.54. CONCLUSION: SMS may be a useful tool for improving health literacy.

Prevalence of depressive symptoms and work-related risk factors among nurses in public hospitals in southern China: a cross-sectional study.

Poor mental health among nurses not only hinders professional performance but also affects the quality of healthcare provided. To improve the prevention and management of depression among nurses in mainland China, we investigated the association between working conditions and depressive symptoms using a cross-sectional study with a sample of 3474 nurses with more than 1 year of work experience in public hospitals in Shenzhen in southern China. Participants completed a structured questionnaire and a validated measure of depressive symptoms. Multivariable linear mixed models were used to identify work-related risk factors for depressive symptoms scores. An estimated 38% of nurses had depressive symptoms. More than 10% of the nurses often experienced workplace violence, and 64.22% encountered it occasionally. Depressive symptoms were associated with frequent workplace violence, long working hours (more than 45 hours per week), frequent night shifts (two or more per week), and specific departments. These findings indicate that interventions to minimize workload and improve nurse-patient relationships are essential to combat depressive symptoms among nurses. Additionally, in the prevention and management of depression among nurses, we must consider inter-department differences.

[The status and risk factors of self-health management among community residents in Shenzhen].

OBJECTIVE: To analyze the risk factors of the self-health management among Shenzhen's community residents by surveying the status of the self-health management. METHODS: Multi-stage cluster random sampling was used in this study. The estimated sample size was 6 400 of the study, and the actual number of the subjects was 6 413, who were from 32 communities in Shenzhen. All the subjects were investigated by using a self-devised questionnaire on July 2012. The contents of the questionnaire included sociodemographic characteristics of genders, age, household register, marriage suatus, degrees of education, income, investment of health, family population, the status of self-health management, self-health assessment, illness and injury in the last two weeks, chronic diseases and in hospital last year. Through binary logistic regression, factors influencing the self-health status were analyzed. RESULTS: The proportion of self-health management among the residents was 29.47% (1 890/6 413), and the proportion was 37.26% (392/1 052) among the first ten chronic disease patients. The proportions of diabetes mellitus, anemia, cardiovascular disease, chronic bronchitis and hypertension patients were higher, which were 46.67% (35/75) , 41.94% (26/62), 38.96% (30/77) , 38.95% (37/95) and 38.93% (102/262) respectively. The binary regression analysis results showed that the effect factors of the self-health management were high age (OR = 1.22, 95% CI: 1.15-1.30) , females (OR = 1.20, 95% CI: 1.07-1.34) , high culture (OR = 1.24, 95% CI: 1.15-1.34) , high monthly income (OR = 1.07, 95% CI: 1.00- 1.13) , large family population (OR = 1.23, 95%CI: 1.10-1.38) , household register in Shenzhen (OR = 1.13, 95% CI: 1.00-1.29) , chronic diseases (OR = 1.22, 95% CI: 1.05-1.42). CONCLUSION: The proportion of self-health management among the community residents in Shenzhen was not high. We should put more effort on construction of health management system, and take action on intervention of the risk factor of health management status.

Prevalence of anxiety and depressive symptoms and related risk factors among physicians in China: a cross-sectional study.

BACKGROUND: Physicians' poor mental health not only hinders their professional performance and affects the quality of healthcare provided but also adversely affects patients' health outcomes. Few studies in China have evaluated the mental health of physicians. The purposes of this study are to quantify Chinese physicians' anxiety and depressive symptoms as well as evaluate associated risk factors. METHODS: In our study, 2641 physicians working in public hospitals in Shenzhen in southern China were recruited and interviewed by using a structured questionnaire along with validated scales testing anxiety and depressive symptoms. Multivariable logistic regression models were used to identify risk factors for anxiety and depressive symptoms. RESULTS: An estimated 25.67% of physicians had anxiety symptoms, 28.13% had depressive symptoms, and 19.01% had both anxiety and depressive symptoms. More than 10% of the participants often experienced workplace violence and 63.17% sometimes encountered it. Among our study population, anxiety and depressive symptoms were associated with poor self-reported physical health, frequent workplace violence, lengthy working hours (more than 60 hours a week), frequent night shifts (twice or more per week), and lack of regular physical exercise. CONCLUSIONS: Our study demonstrates that anxiety and depressive symptoms are common among physicians in China, and the doctor-patient relationship issue is particularly stressful. Interventions implemented to minimize workload, improve doctor-patient relationships, and assist physicians in developing healthier lifestyles are essential to combat anxiety and depressive symptoms among physicians, which may improve their professional performance.

[Studies on direct and indirect economic burden of disease and related factor in countryside of Qingdao city in 2001].

OBJECTIVE: To study the condition of economic burden of disease in the countryside and to explore the related factors. METHODS: Human capital method and two-step method were used in the calculation of economic burden of disease. RESULTS: The total economic burden of disease among 3359 persons was 3072 225 Yuan. Noncommunicable conditions were accounted for 62.95%, while communicable disease, maternal and perinatal conditions accounted for 24.25%, and injury accounted for 9.83% respectively. The direct economic burden of disease was 1,559,619 Yuan and the indirect economic burden of disease was 1,472,606 Yuan. The economic burden of disease for each person was 914 Yuan. The equal burden of disease among patients with disability and without disability were 3070 Yuan and 680 Yuan respectively (P < 0.001). There was significant difference among different age groups. The influencing factors were found to include having noncommunicable disease, age, disability and the condition of marriage. CONCLUSION: Corresponding policy to cope with conditions of different age groups needs to be developed to reduce the economic burden of disease in the countryside.
