Diabetes patients in China is large in number, low level of health literacy, and their self management mainly relies on community doctor's health propaganda and education, as a result, it is very important to train community healthcare professionals to improve their communication skills with patients.Guided by the Social Cognitive Theory (SCT), the researchers developed a literacy-addressing training model specifically through: 1) low literacy healthcare education materials written in plain language, simple text, maximal white space, and behavior-oriented images or pictograms;2) a standardized health communication curriculum to promote simple communication with decreased jargon usage, teach teach back, and enhance shared goal-setting;3) use of standardized patients to enhance doctor-patient communication training;and 4) MOOC and a series of videos demonstrating doctor-patient communication scenarios.The novel training model can be used in continuing medical education through traditional on-site classes or by E-learning platform.It is expected to improve the communication skills of community doctors and patients, improve the satisfaction of both doctors and patients, and the effect of patients' self-management.

Factors in uterus may be important in the aetiology of type 2 diabetes.Malnutrition during early life can affect insulin secretion and result in insulin resistance,and such effects are markedly exaggerated when facing over-nutrition in later life.This paper gives a review about the population evidence and epigenetic mechanism in the generational susceptibility to type 2 diabetes.

To reduce morbidity and mortality and improve quality of life for patients with diabetes,the China Da Qing Diabetes Prevention Study was initiated as health education and behavior intervention in the 1980s in Daqing City.576 subjects with impaired glucose tolerance (IGT) were recruited and randonized into a clinical trial,either to a control group or to one of three active treatment groups:diet only,exercise only,or diet plus exercise.Follow-up evaluation examinations were conducted 2-year intervals over a 6-year period and after 20-year period to identify subjects who developed diabetes mellitus.Diet and/or exercise interventions led to a significant decrease in the incidence of diabetes over a 6-year and 20-year period among those with IGT.The implementation of this study indicates that diabetes can be prevented through health education and behavioral intervention,and the prevention of diabetes and other chronic diseases should also focused on strengthening the muhi-sectoral cooperation,developing professional skills of health care providers,re-orientating health care services toward prevention of illness and promotion of health.

OBJECTIVETo study the relationship between obesity at different ages and the risk of endometrial cancer in urban Shanghai, China.

METHODSIn a population-based case-control study conducted in urban Shanghai, in-person interviews and anthropometric measurements were completed for 497 women at age 30 to 69 and an equal number of controls frequency-matched to cases on age distribution. All cases were newly diagnosed with endometrial cancer from January 1, 1997 to June 30, 2000. Unconditional logistic regression model was employed to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of the obesity at different ages.

RESULTSAfter adjustment for some potential confounding variables, neither adolescent height nor weight was significantly related to endometrial cancer. Obesity in adulthood, except around 20 years old, was associated with elevated risks, with odds ratios for the highest versus lowest quartile of body mass index (BMI) being 1.5 (95% CI: 1.0 - 2.1), 1.7 (95% CI: 1.2 - 2.4), 1.9 (95% CI: 1.3 - 2.8) and 1.7 (95% CI: 1.0 - 2.7) at ages 30, 40, 50 and 60, respectively. Weight gain of more than 7.5 kg at different 10-year intervals in adulthood were associated with increased risk of endometrial cancer, whereas only weight gain more than 15% of initial weight from 40 to 50 years old significantly related to the risk. Only weight loss from ages 20 to 30 was inversely associated with endometrial cancer risk (OR = 0.4, 95% CI: 0.2 - 0.8). Current body weight, BMI and waist-to-hip ratio (WHR) were independent risk factors to endometrial cancer while standing height and sitting-to-standing height ratio were unrelated to the risk of endometrial cancer.

CONCLUSIONResults indicated that adolescent obesity was unrelated to endometrial cancer. General obesity in adulthood, as well as body fat distribution, were associated with the risk of endometrial cancer independently. Weight changes before and after age 30 had different effects on the risk of endometrial cancer.

Objective To investigate the levels of literacy and numeracy in type 2 diabetes patients with poor glycemic status in communities of Shanghai,China,and to evaluate their associations with blood glucose level.Methods A total of 800 type 2 diabetes patients with recent HbA1c≥7.5％ or fasting plasma glucose level ≥10 mmol/L were recruited from 8 communities in Minhang district and Changning district of Shanghai,China,and were interviewed using a structured questionnaire during February 2015 and March 2016.Literacy and numeracy levels of all patients were evaluated using the validated Health Literacy Management Scale (HeLMS) and the 5-item version Diabetes Numeracy Test (DNT-5),respectively.Results The patients included in this study were observed to have higher levels of health literacy,with a median score of HeLMS being 116 [interquartile range (IQR),108-120] and a median correct rate of DNT-5 of 80％ (IQR,60％-100％).Age,educational level and occupation were significantly related with health literacy levels and numeracy.Sex and income were closely related with health literacy levels.HeLMS score was not significantly associated with HbA1c level (P =0.383),while the lower correct rate of DNT-5 was linked with a higher level of HbA1c.The median HbA1c level was 8.3％ (IQR 7.7％-9.4％) in the patients with the lowest tertile of DNT-5 correct rate,significantly higher than 8.2％ (IQR:7.5％-9.2％) in the medium and 8.0％ (IQR:7.5 ％-8.8 ％) in the highest tertile group (P =0.009).Conclusions Diabetes patients with poor glycemic status in communities of Shanghai have high levels of health literacy,which was significantly related with age,sex,educational level,occupation and income.Ability in numeracy may be a more important influence factor than health literacy for glycemic status of diabetes patients.

Background and objective Low-dose spiral computed tomography(LDCT)has been recommended for lung cancer screening in high-risk populations.However,evidence from Chinese populations was limited due to the dif-ferent criteria for high-risk populations and the short-term follow-up period.This study aimed to evaluate the effectiveness in Chinese adults based on the Lung Cancer Screening Program in Minhang District of Shanghai initiated in 2013.Methods A total of 26,124 subjects aged 40 years or above were enrolled in the Lung Cancer Screening Program during the period of 2013 and 2017.Results of LDCT examination,and screen-detected cancer cases in all participants were obtained from the Report-ing System of the Lung Cancer Screening Program.The newly-diagnosed cases and their vital status up to December 31,2020 were identified through a record linkage with the Shanghai Cancer Registry and the Shanghai Vital Statistics.Standardized incidence ratio(SIR)and 95％CI were calculated using the local population at ages of 40 or above as the reference.Proportions of early-stage cancer(stage 0-Ⅰ),pathological types,and 5-year observed survival rates of lung cancer cases were estimated and compared between the cases derived from the screened and non-screened populations.Cox regression models were applied to evaluate the hazard ratio(HR)and 95％CI of LDCT screening with all-cause death of the lung cancer cases.Results The crude and age-standardized incidence of lung cancer in screened population were 373.3(95％CI:343.1-406.1)and 70.3 per 100,000 person-years,respectively,with an SIR of 1.8(95％CI:1.6-1.9),which was observed to decrease with following-up time.The early-stage cancer accounted for 49.4％of all lung cancer cases derived from the screened population,significantly higher than 38.4％in cases from the non-screened population during the same period(P＜0.05).The proportion of lung adenocarcinoma(40.7％vs 35.9％)and 5-year survival rate(53.7％vs 41.5％)were also significantly higher in the cases from the screened popu-lation(all P＜0.05).LDCT screening was associated with 30％(HR=0.7,95％CI:0.6-0.8)reduced all-cause deaths of the cases.Conclusion The participants of the screening program are at high-risk of lung cancer.LDCT favors the early-detection of lung cancer and improves 5-year survival of the screened cases,indicating a great potential of LDCT in reducing the disease burden of lung cancer in Chinese populations.

Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in adult residents of Shanghai Pudong New Area. Methods A total of 5584 residents aged 20-80 years old were randomly selected from Shanghai Pudong New Area through multistage sampling and interview between April and July 2008. Fasting blood samples and morning urine samples were collected to detect Scr and urinary albumin and creatinine. Urine albumin to creatinine ratio (ACR) and glomerular filtration rate (GFR) was calculated to estimate the renal function. Logistic regression model was used to examine the associations of demographic and lifestyle factors with indicators of kidney damage. Results The age-standardized prevalence of albuminuria, reduced renal function and CKD was 9.9% (male 8.0%, female 12.4%), 1.1% (male 1.3%, female 0.9%) and 11.0%(male 8.8%, female 12.7%), respectively. The prevalence of CKD was higher in female and increased with age. No significant difference in the prevalence was observed between urban and rural areas. Elder, female, high blood pressure, high fasting glucose, dyslipidemia and obesity were associated with CKD independently. Conclusions The prevalence of CKD in Shanghai Pudong New Area is comparable to that previously reported in China or other developed countries, and even higher. CKD is going to be a public health problem and warrants the community-integrated control strategy to prevent the incidence of end-stage renal disease (ESRD) and related complications.

Objective To evaluate the association between birth weight and subsequent risk of type 2 diabetes (T2DM) across two generations in Chinese females.Methods A cross-sectional survey was conducted among 10 324 blood-related females in Shanghai from November 2012 to January 2013.A structured questionnaire was used to collect data about demographic information,birth weight,lifestyle factors and diagnosis of T2DM.Path analysis was performed to estimate the matemal effect of birth weight and diabetes status on their offspring,and mediation analysis was conducted to test whether birth weight mediates the association between maternal and daughters' diabetes status.Results A positive association was observed between maternal and daughters' birth weight.One kg increase in maternal birth weight was associated with an average of 0.335 (95％CI:0.307-0.363) kg elevated birth weight in female offspring.Maternal diabetes status was also related with an average of 0.066 (95％ CI:0.025-0.107) kg increase in birth weight and tripled risk of subsequent T2DM (OR=3.173,95％CI:1.946-5.174) in female offspring.In all subjects aged ≥20 years,no significant relationship was observed between birth weight and risk of T2DM subsequently after adjusting for age.Offspring' s birth weight,as a mediator of maternal and daughters' diabetes status,explained 2.8％ of their association.Conclusion Maternal birth weight and diabetes status may influence their female offspring' s birth weight and subsequent risk of T2DM.
