RESUMO
OBJECTIVE@#This study aimed to evaluate the risk factors of radiation-induced caries by using a multiple linear regression equation and to provide the basis for the effective prevention of radioactive caries.@*METHODS@#A total of 166 patients with head and neck cancer who underwent radiotherapy were selected as subjects. The number of decayed, missing or filled surfaces were recorded. Questionnaire contents included age, sex, radiation dose, and radiotherapy techniques. Multiple stepwise regression analyses were performed to identify the risk factors of radiation-induced caries.@*RESULTS@#Multiple stepwise regression analyses indicated that the main risk factors of radiation-induced caries were plaque index, radiotherapy techniques, time after radiotherapy, and radiotherapy dose.@*CONCLUSIONS@#The awareness of dental care and caries treatment should be improved to reduce the occurrence of radiation-induced caries in patients with head and neck cancer. In addition, intensity modulated radiation therapy should be employed to decrease the radiation exposure dose received by teeth.

Objective To evaluate the intervention effects of peer support education mode for type 2 diabetes control in rural residents.Methods A random cluster sampling method has been used,including 300 rural residents aged above 18 years old from three villages (184 in control group,116 in intervention group),in order to proceed the physical check-up and health education programs.Unchanged rate,transfer rate of patients,rate of impaired glucose tolerance,turn normal rate and other biochemical indicators of patients and people with impaired glucose tolerance from control group and intervention group were analyzed,to evaluate the intervention effects of peer support education mode.Results The glycemic control rate of intervention group for patients and people with impaired glucose tolerance (72.2％ and 71.4％) were higher than control group (43.6％ and 26.7％),but the unchanged rate of intervention group (13.9％ and 0.0％) were lower than control group (42.3％ and 73.3％).Patients with diabetes or glucose intolerance in the education group improved significantly in waist-to-hip ratio,uric acid,total cholesterol and HDL-C.Glycemic hemoglobin level also improved significantly in diabetes patients of the education group.Conclusion Peer support for education intervention seemed beneficial for diabetic control.The combination of education and effect evaluation was important in the evaluation of diabetes prevention and control.Peer support education also benefited the blood glucose control in general population.

RESUMO
Objective Health education was provided among driving coaches with overweight or obesity to improve their self-healthcare awareness.Methods Of 116 driving coaches from Changping District who underwent physical examinations and biochemical tests, 79 were confirmed to have overweight or obesity and received body weight management.Results Following 3 years of health management, 79 overweight or obese participants showed significant improvement in waist circumference ((93.5±8.4) vs (92.0±9.5) cm), systolic blood pressure ((130.8±12.4) vs (127.8±11.6) mm Hg, 1 mm Hg=0.133 kPa), diastolic blood pressure ((87.0±9.7) vs (85.6±9.3) mm Hg), high-density lipoprotein cholesterol ((1.1±0.4) vs (1.2±0.3) mmol/L), and glucose ((5.6±1.5) vs (5.4±1.6) mmol/L) (all P0.05).Conclusion Overweight and obesity in middle-aged adults is of concern and needs long-term effective interventions.
RESUMO
Objective To explore the relationship of hypertension prevalence and body weight in children and teenagers in Changping district of Beijing. Methods With stratified cluster sampling, 4 247 students (2 090 female and 2 157 male) aged 7~18 yrs from primary and middle schools in Changping district were investigated in May to October, 2007, and examined on their body height, weight, systolic pressure, diastolic pressure, fasting blood glucose, etc. Data was analyzed with SPSS11.5. Result The rate of overweight and obesity was 13.47% 572 / 4 247); Hypertension 30.02% (1 275 / 4 247); The prevalence rates of hypertension in children-teenagers with overweight & obesity and with normal weight were 53.15% and 27.40%, respectively,(?2=153.74, P
