[A cross-sectional study of prevalence of chronic kidney disease and related factors in adults in Anhui province].

Objective: To understand the prevalence of chronic kidney disease (CKD) and related factors in adults in Anhui province based on the data of Chinese Chronic Diseases and Nutrition Surveillance program (2018) in Anhui. Methods: Multi-stage stratified cluster random sampling was used to select participants aged ≥18 years. Moreover, questionnaire survey, body measurements and laboratory tests were conducted. The complex weighting method was used to estimate the prevalence of CKD in residents with different characteristics, and complex sampling data logistic regression model was used for multivariate analysis to identify related risk factors. Results: A total of 7 181 participants were included. The overall prevalence of CKD was 11.06% in adults in Anhui, and the prevalence was 12.49% in women and 9.59% in men (P<0.05). The moderate, high and very high risk for CKD progression were 8.66%, 2.02% and 0.38%, respectively. Multivariate analysis showed that age (OR=1.03, 95%CI: 1.00-1.05), BMI (OR=1.05, 95%CI: 1.01-1.09), being woman (OR=1.38,95%CI: 1.22-1.55), hypertension (OR=2.50, 95%CI: 1.76-3.56), diabetes (OR=2.28, 95%CI: 1.51-3.43), dyslipidemia (OR=1.26, 95%CI: 1.11-1.43) and hyperuricemia (OR=2.16, 95%CI: 1.68-2.78) were risk factors for CKD. Conclusion: The prevalence of CKD in adults in Anhui was relatively high and age, gender, BMI, hypertension, diabetes, dyslipidemia and hyperuricemia were found to be associated with the prevalence of CKD. To prevent CKD and its complications, attention should be paid to the management of related risk factors, including overweight and obesity, hypertension, diabetes, dyslipidemia and hyperuricemia.

[Study on the relationships between precollege sexual abuse experiences at different stages and adult attachment in college students].

Objective: To explore the association between precollege sexual abuse experiences at different periods and adult attachment in college students. Methods: In October 2018,a total of 4 034 college students were selected from 4 colleges in Hefei City by using the stratified cluster sampling method. A self-designed questionnaire was used to investigate the demographic characteristics, sexual abuse experience, and attachment style of participants. Multivariate linear regression analysis was performed to analyze the association between different periods, types of precollege sexual abuse experiences and attachment style in college students. Results: The rate of total precollege sexual abuse, noncontact sexual abuse, and contact sexual abuse was 14.1% (569), 12.7% (512) and 5.4% (219), respectively. Multivariate linear regression analysis showed that secure attachment [ß(95%CI)=-0.205 (-0.292, -0.117)] was negatively correlated with total precollege sexual abuse experiences, whereas anxiety attachment [ß(95%CI)=0.211 (0.110, 0.310)], avoidant attachment [ß(95%CI)=0.117 (0.020, 0.216)] were positively correlated with total precollege sexual abuse experiences. The number of periods of precollege noncontact sexual abuse was negatively correlated with secure attachment [ß(95%CI)=-0.106(-0.171, -0.041)]and positively correlated with anxiety attachment [ß(95%CI)=0.158 (0.084, 0.231)]and avoidant attachment [ß(95%CI)=0.080 (0.008, 0.152)]. The noncontact [ß(95%CI)=0.427 (0.018, 0.775)] and contact sexual abuse [ß(95%CI)=0.468 (0.251, 0.687)] in high school were positively correlated with anxiety attachment (P<0.05). Conclusion: Different periods, types of precollege sexual abuse experiences were all associated with adult attachment in college students.

[Association between suffering experiences from precollege peer bullying at different stages and the quality of health-related life among college students].

Objective: To explore the effects of precollege peer bullying at different stages, on quality of life (QOL) among college students. Methods: A stratified cluster sampling method was used to select participants in October, 2018. Cluster sampling method was adopted to recruit a sample of 4 034 college students from four universities in Hefei city, Anhui province. Relations between peer bullying at different stages before entering college, and the quality of life, were investigated. t test and analysis of variance were used to compare the differences of QOL in different groups. Multiple linear regression models were used to assess the associations between various types of peer bullying at different stages and the QOL at precollege days. Results: Among all the 4 034 college students under study, mean scores of the 4 dimensions of QOL appeared as physical (12.61±2.02), psychological (14.09±2.62), social relationship (13.72±2.71) and environment (13.77±2.46), respectively. After adjusting the confounding factors, data from multiple linear regression showed that, factors as verbal bullying victimization during primary school (ß=-0.21)/secondary school (ß=-0.27)/or at both periods (ß=-0.56), relational (ß=-0.21) and physical (ß=-0.38) bullying victimization in secondary school, and physical bullying victimization in both periods (ß=-0.67) were negatively correlated with the physical dimension of QOL. Verbal bullying victimization in both periods (ß=-0.41) and relational bullying victimization in secondary school (ß=-0.42) were negatively correlated with psychological dimension of QOL. Factors as relational (ß=-0.32) and physical (ß=-0.51) bullying victimization in secondary school, physical/cyber bullying victimization in both periods (ß=-0.57) were negatively correlated with the social dimension of QOL. Verbal bullying victimization during primary school (ß=-0.20) and both periods (ß=-0.46), relational bullying perpetration during primary school (ß=-0.35) or at both periods (ß=-0.90) were negatively correlated with the environmental dimension of QOL (All P<0.05). Index related to bullying victimization (ß=-0.33, -0.36, -0.30, -0.33) and bullying perpetration ß=-0.28, -0.31, -0.23, -0.28) were both negatively correlated to all the 4 dimensions (physical, psychological, social relationship and environment) of QOL (P<0.001). Conclusions: Various forms of peer bullying experiences occurring before college, were associated with the decreased scores of QOL in different domains, among the university students. Programs on prevention and control of peer bullying in different stages before college days seemed important thus should be strengthened.
