ABSTRACT
Objective To explore the relationship between environmental factors as urinary cadmium and type 2 diabetes mellitus (DM) in adults.Methods Case-control study was adopted,including 166 cases and 427 controls.General characteristics of the subjects were collected by a structured questionnaire.FPG,biochemical indexes and urinary cadmium (UCd) were detected respectively,while UCd was corrected with creatinine.Unconditioned logistic regression model was applied to analyze the relationship between UCd and DM.Results Levels of UCd appeared higher in cases with the following characteristics as:having primary school education (P=0.016),being female (P=0.013),being non-smokers (P=0.014) or non-alcoholic (P=0.025),and with BMI＞25.00 kg/m2 (P=0.040,P=0.025) than those appeared in the control group.Same results were shown in the 60-69 years (P=0.024) old group.Data from the unconditional logistic regression analysis showed that family history of DM (OR=3.19,95％ CI:1.45-7.03),education status (OR=1.50,95％CI:1.08-2.08) and UCd (OR=1.61,95％CI:1.08-2.41) were influencing factors on DM.Conclusion A close association between UCd and DM was noticed.UCd appeared a risk factor on DM that called for setting up related prevention program to reduce the exposure of Cd and to control the risk on DM.

ABSTRACT
Objective This paper aims to describe the prevalence of unhealthy weight control behaviors and its related factors amongst female medical college students. Method Questionnaire surveys were conducted among a total of 798 medical students recruited by cluster random sampling in Jining Medical College from April 5 to 16, 2013. Result A total of 728 valid questionnaires were collected; 29 participants (4.0%) were overweight and 9 participants (1.2%) were obese; 250 participants (34.3%) were losing weight. Among participants who had experience of losing weight, unhealthy weight control methods mainly included not eating staple food (17.3%), drinking diet tea (16.1%), fasting (12.9%), taking diet drug (8.6%), inducing diarrhea (5.4%), inducing vomiting (2.0%), enema (1.5%), etc.; 29.0% (211/728) of participants had unhealthy weight control behaviors. The rates of being weak (c2=19.681, P=0.000), failure to concentrate (c2=12.031, P=0.001), dizziness (c2=5.461, P=0.019), irregular menstruation (c2=24.628, P=0.000), anorexia (c2=32.008, P=0.000), insomnia (c2=11.021, P=0.001) and anxiety (c2=14.402, P=0.000) among participants who had unhealthy weight-control behaviors were higher than those of participants without unhealthy weight?control behaviors. Multinomial logistic regression indicated that the factors associated with unhealthy weight control behaviors were senior class (OR=2.041;95%CI:1.336-3.111), high average family income (OR=1.758;95%CI:1.183-2.611), weight loss intention (OR=6.756;95%CI:1.541-29.626),not hesitating to delay learning (OR=1.594;95%CI:1.078-2.359),insisting on weight loss process regardless of discomfort (OR=2.008;95%CI:1.245-3.238), slimming purpose (body beauty) (OR=1.786;95% CI: 1.095-2.913), and slimming purpose (fashion) (OR=3.169; 95%CI: 1.545-6.498). Subjects with longer dinner time (OR=0.556; 95% CI: 0.341-0.907) and preferring light diet (OR=0.593; 95% CI: 0.406-0.865) had lower rate of unhealthy weight control behaviors. Conclusion Part of female college students are lacking proper understanding of self body shape and unhealthy weight control behaviors and had done harm to their health.
