Abstract:
Objective To explore the mediation effect of appearance stress on the relationship between physical appearance perfectionism and mental health.Methods Seventy plastic and anesthetic surgery patients selected with random selection were surveyed with Physical Satisfaction Scale(PSS),Social Appearance Anxiety Scale(SAAS),Physical Appearance Perfectionism Scale(PAPS),Appearance Self-Esteem Scale(ASES),Appearance Stress Scale(ASS),and Body Image Concern Inventory(BICI)on the day before the operation.The data were analyzed with hierarchical regression and correlation.Results Significant correlations were found among worry,imperfection,appearance stress,and mental health(P<0.01).The appearance stress partially mediated the relationship between worry about imperfection and general physical satisfaction,facial satisfaction,and after introducing appearance stress,the standardized coefficient were reduced from 0.484 and 0.470 to 0.314 and 0.306,respectively,with significant differences(P<0.05).The appearance stress fully mediated the relationship between worry about imperfection and appearance self-esteem,and after introducing appearance stress,the standardized coefficient was reduced from 0.452 to 0.153,with a non-significant difference(P >0.05).The appearance stress did not mediate the relationship between worry about imperfection and social appearance anxiety,body image concern and figure satisfaction.Mediation of appearance stress was not existed between hope for perfection and mental health because there was no correlation between hope for perfection and appearance stress and mental health.Conclusion Physical appearance perfectionism could negatively influence mental health directly and also have negative effect on mental health indirectly through appearance stress.

Abstract:
Objective To investigate the association between occupational physical activity,body mass index(BMI)and uterine leiomyoma(UL)in middle aged and elderly women.Methods A hospital-based case control study was conducted.Totally 353 UL patients aged 35-62 years were selected as cases from the First Affiliated Hospital and the Third Affiliated Hospital of Liaoning Medical College and Jinzhou Women and Children's Hospitial.The controls(n=353)were patients suffering from diseases not related with UL.All subjects were interviewed using a structured interviewer-administrated questionnaire.The height and weight of the subjects were measured simultaneously.Then physical activities were investigated using International Physical Activity Questionnaire(IPAQ).The odds ratios(OR)and their 95% confidence intervals(95%CI)of UL for occupational physical activities and BMI were estimated with multiple logistic regression model.Results Socio-demographic characteristics(age,marital status,educational level,and familial income)were not significantly different between the two groups(P>0.05).However,the percentage of controls(34.28%)with number of live births ≥2 was significantly lower than the cases(44.19%)(P=0.026).Moderate occupational physical activity could decrease the risk of UL(OR=0.679,95%CI:0.480-0.925;P=0.007).Compared with the subjects with normal BMI,both overweight and obesity had higher odds of UL(OR=1.571,95%CI:1.053-2.182,;P=0.001;OR=1.875,95%CI:1.191-2.774;P=0.002,respectively).Moderate occupational physical activity could decrease the risk of UL in the subjects with normal BMI(OR=0.455,95%CI:0.215-0.960;P=0.039).After adjustment for multiple potential confounders,the results remained unchanged.For the subjects with higher BMI(24.00-27.99 kg/m2),the OR in third quartile of metabolic equivalents was 0.389(95%CI:0.182-0.832,P=0.015)compared to the lowest quartile.Conclusion Moderate physical activity and normal BMI can contribute to lower incidence of UL.

Objective To explore the prevalence of depression and its influencing factors among retirees in communities,and to offer basic data for community intervention.Methods The participants were selected with cluster sampling and general demographic scale,Geriatric Depression Scale-15(GDS-15),Well Being Index(WHO-5),Social Support Questionnaire and Self-Commitment Sleep Scale were used in the survey.The data were processed with EpiData 3.0 and analyzed with statistical package SPSS 18.0.Results The prevalence of depression symptoms was 23.7% among the community retirees.There were significant associations between depression and marital status,age,education level,insomnia,life satisfaction,and social support by univariate analysis(P<0.05).The results of multivariate logistic analysis indicated that the protective factors of depression symptoms included at the age of 60-69 years(odds ratio [OR]=0.53,95% confidence interval [95%CI]=0.36-0.78),at the age of 70-80 years(OR=0.47,95%CI=0.28-0.79),high school or equivalent education background or above(OR=0.49,95%CI=0.30-0.80),and with objective social support(OR=0.47,95%CI=4.69-11.99),while the risk factors included manual labor history(OR=1.67,95%CI=1.02-2.75)and having worse life satisfaction(OR=7.50,95%CI=4.69-11.99).Conclusion Improving life satisfaction,increasing social support and reducing insomnia are helpful for the control of depression symptoms among community retirees.
