Objective To understand the situation of iodine deficiency disorders and iodine nutrition of children in Yunnan Province after the implementation of new standard of salt iodine,and provide the basic data for prevention and control of iodine deficiency disorders.Methods Using multistage sampling method,Yunnan provincial evaluations for iodine deficiency disorders elimination were carried out.According to the comparative analysis of 2010 (pre-adjustment) and 2015 (post-adjustment) evaluation results,the changes of the median of salt iodine,the coverage rate of iodized salt,the qualified rate of iodized salt,the rate of qualified iodized salt consumption,goiter rate of school children aged 8-10 and the median of urinary iodine were evaluated.Salt iodine was tested using the "Salt Industry General Test Method for Determination of Iodine" (GB/T 13025.7-1999);thyroid volume examination of children using B-scan ultrasonography,thyroid volume calculation and enlargement judgment using "Diagnostic Criteria for Endemic Goiter" (WS 276-2007);and urinary iodine detection using "Urinary Iodine Arsenic Cerium Catalytic Spectrophotometry" (WS/T 107-2006).Results The medians of salt iodine in 2010 and 2015 were 30.6 and 22.4 mg/kg,respectively,the difference was statistically significant (U =317 503.50,P ＜ 0.01).The coverage rates of iodized salt in 2010 and 2015 were 99.6％ (1 681/1 688) and 98.9％ (2 592/2 622),the qualified rates of iodized salt were 98.6％ (1 657/1 681) and 89.7％ (2 325/2 592),and the rates of qualified iodized salt consumption were 98.2％ (1 657/1 688) and 88.7％ (2 325/2 622),and the differences were statistically significant (x2 =6.42,125.11,130.18,P ＜ 0.01);the rates of children goiter in 2010 and 2015 were 0.8％ (25/3 272) and 1.4％(44/3 245),respectively;the medians of urinary iodine of children were 289.0 and 157.3 μg/L,respectively,the difference was statistically significant (U =1 121 669.50,P ＜ 0.01).Conclusion After decreasing of salt iodine level starting from 2012 in Yunnan Province,the children iodine nutrition condition is in a more proper level.

Objective:To understand the contents of edible salt iodine and urinary iodine of children and pregnant women in Yunnan Province, and to evaluate the iodine nutrition status, so as to provide a basis for scientific prevention and treatment of iodine deficiency disorders (IDD).Methods:From November to December 2020, one county (city) was selected from each prefecture (city), two townships (towns and streets) were selected from each county (city) and two villages (neighborhood committees) were selected from each township (town and street) from each of the 16 prefectures (cities) in Yunnan Province as the investigation sites. A total of 20 non-boarding children (male and female balanced) aged 8 - 10 years old were selected from each primary school in each village (neighborhood committee) to collect salt and urine samples. A total of 80 children were investigated in each county (city). A total of 20 pregnant women were selected from each township (town and street) to collect salt and urine samples. A total of 40 pregnant women were investigated in each county (city). All salt samples and urine samples were tested for iodine contents.Results:A total of 2 009 salt samples and 2 041 urine samples (1 375 for children, 666 for pregnant women) were collected from children aged 8 - 10 years old and pregnant women in 16 counties (cities) of Yunnan Province. Among them, the median salt iodine was 26.0 mg/kg, the coverage rate of iodized salt was 100.0% (2 009/2 009), the qualified rate of iodized salt was 98.7% (1 982/2 009), and the consumption rate of qualified iodized salt was 98.7% (1 982/2 009). The difference of salt iodine content in key populations in different counties (cities) was statistically significant ( H = 258.98, P < 0.01). The median urinary iodine of children aged 8 - 10 years old was 188.5 μg/L. There was statistically significant difference in urinary iodine content among children of different ages ( H = 29.45, P < 0.01), but there was no statistically significant difference in urinary iodine content among children of different genders ( H = 1.43, P > 0.05). In addition, the median urinary iodine of pregnant women was 141.9 μg/L, 52.1% (347/666) was < 150 μg/L. There was statistically significant difference in urinary iodine content of pregnant women in different counties (cities, H = 88.32, P < 0.01). Conclusions:The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in key populations of Yunnan Province are more than 90%, and the iodized salt supply is good. Iodine nutrition of children aged 8 - 10 years old is at an appropriate level (100 - 199 μg/L); iodine nutrition of pregnant women is in an state of iodine deficiency ( < 150 μg/L). It is suggested to strengthen IDD monitoring and health education among key populations, improve residents' awareness of disease prevention, and make scientific iodine supplementation.

Objective:To investigate the orthopedists' cognition on Chinese Osteoarthritis Guideline (2018 Edition).Methods:Questionnaire about Chinese Osteoarthritis Guideline (2018 Edition) was developed and sent to orthopedists via an invitation link to fill out after authorization from Chinese Osteoarthritis Association. The content of the questionnaire included the basic personal information of the physician, the awareness rate of the guidelines, the evaluation of the guidelines, and its application effects. The survey duration was from September 2019 to December 2019. Multivariate logistic regression and linear regression analysis were performed for the guideline awareness rate and comprehensive score, respectively.Results:A total of 628 physicians completed the questionnaire, of which 623 of 628 (99.2%) were available. About 72.4% of the orthopedists knew the guideline. The awareness rate was statistically related to the education of the physicians ( P<0.05). Respondents' overall score for the guideline was 8.39 with methodological score 8.28. A total of 41.2% of orthopedists thought that the guideline was very good compared with the European and American guidelines, and the clinical problem coverage rate was 78.6%. There is a statistically significant difference in the appraisal of the recommendations ( χ2=138.9, P<0.05) . More than 40% of orthopedists believed that the guidelines were of great help to orthopedists and patients, and that the guide could be promoted to the primary hospitals. Conclusion:After one year publication of Chinese Osteoarthritis Guideline (2018 Edition), most orthopedists have understood the present guideline and applied recommendations in clinical practice. However, the guideline need to be further promoted and disseminated in the future.

OBJECTIVEIn order to understand the iodine nutritional status, after the salt-iodine content was showed a reduction in 2012 and to evaluate the current situation after the new standards was brought into force to the general population in an experimental community of Yunnan province.

METHODSRandomly sampled urine and salt were collected, to test the iodine concentration in the study-site. Pre-and post-levels of the iodized salt under the provision of the new standards, were identified.

RESULTSof this study were gathered upon 3 weeks or 3 months, respectively. Results Data from the three randomly chosen study sites showed that the urine iodine concentration in the general populations was reducing gradually. In the general population, medians of Urine Iodine (MUI) were 279.71 µg/L, 239.64 µg/L and 226.26 µg/L, respectively. Proportion of the urine iodine value for 100-199 µg/L increased but ≥300 µg/L decreased, after the new standard was put into practice. Both homogeneity and stability of the new standard on iodized salt seemed to be good.

CONCLUSIONIodine nutrition in general population appeared reasonable under the use of newly set salt-iodine standards in general population living in Yunnan province.
