The study was conducted on 82 simple goiter patients and 91 Basedow patients after at least one year using iodized salt daily. The results showed that the uptake of radioactive iodine (RAIU) by the thyroid gland of simple goiter and Basedow patients decreased after 2 and 24 hours taking an oral dose of radioactive iodine. Especially, the decrease was 40-50% in simple goiter patients. The concentration of T3, T4, TSH in the sera was as following: in the simple goiter patients, the concentrations of T3 and TSH were slightly decreased, and the T4 serum concentration was increased. However, all the values were still within the normal range of euthyroidism. In Basedow patients, the concentrations of T3, T4, and TSH have not changed.

OBJECTIVETo draft out the simplified scheme of iodized salt monitoring program to compare with the current scheme, and to study its feasibility.

METHODS8 counties from 4 provinces were selected at different coverage rate of iodized salt. Conduct the monitoring program using the current scheme and the simplified scheme, then compare the results.

RESULTSThe monitoring results of the current scheme showed the coverage rate of iodized salt and adequate iodized salt were 88.1% and 84.8% and the data of the simplified scheme were 85.2% and 79.8% respectively. Five counties reached above 90% of both the coverage rates of iodized salt and adequate iodized salt and the results showed no significant difference between the two schemes. The rates of other three counties were low, and the difference was significant between Dulan and Linxia counties. To the whole samples, the difference was also significant.

CONCLUSIONThe simplified scheme could be applied to those that the coverage rate of iodized salt was quite high or the non-iodized salt was well-distrbuted. However, for those areas with low coverage rate, it might not be suitable. As for the whole nation, it might not be popularized due to the gap of coverage rate between western and eastern areas.

This study was intended to investigate the sodium-related perception, dietary behavior, and practicability of methods for reducing sodium intake(RSI) according to the stage of change in consumers. The survey was conducted to 770 housewives, among them 553 subjects who answered the key questions for the stage of change were categorized into ''aintenance (M)' stage (maintaining reduced salt intake for more than 6 months; n = 287, 51.90%), 'Action (A)' stage (maintaining reduced salt intake for less than 6 months; n=139, 25.14%), and 'Pre-Action (P)'stage (not starting reduced salt intake; n = 127, 22.97%). The subjects in M and A were significantly older than those in P (p < 0.01). The scores of desirable dietary habit and dietary balance were the highest in M followed by A and P. When eating out, the subjects in P considered 'price' more and 'healthiness of food' less than those in M and A did. Among the guidelines for RSI, 'Avoid Processed Foods', 'Eat enough vegetables and fruits' and 'Add little amount of dipping sauce for fried food' were selected as the three easiest items to perform. With regard to the sodium-related perception, the subjects in M considered eating-out food to be more salty than homemade dishes, read nutrition labels more, avoided table salt or dipping sauce for fried food more, and had 'own low-sodium recipe' than those in P (p < 0.001). It is suggested that practicability of actions for RSI and the stage of change should be considered to develop effective personalized education program and nutrition guidance.

This study was to develop and evaluate a nutrition education program to reduce dietary sodium. The school children (218 boys, 226 girls), from 8 elementary schools in the city of Daegu, Korea, were involved in this study. This research was based on the data from two groups of elementary school children, the "education" group (n = 240), and "no-education" group (n = 204). Educational media and programs were developed to educate the education group for four weeks and were presented on the web (www.saltdown.com). After education, the preference for a non-salty taste in the education group increased 10%, compared with those who preferred a non-salty taste before education. There was a significant change away from a preference for a salty taste and a rise in the mean score for nutrition knowledge and dietary attitude in the education group compared to the no-education group (p < 0.05). This study indicates that school children can reduce their dependency on preference for a salty taste and change their high-salt dietary behavior after the education.

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.

OBJECTIVETo analyze the nutritional ingredients of daily consumed pre-packaged foods in Chinese adult residents.

METHODSFrom October to December 2013, the nutrition labels of pre-packaged foods consumed in continuous 7 days by 706 adult residents were collected by multi-stage stratified cluster random sampling in 18 communities with 360 households in 9 cities in China including Beijing, Shanghai, Chongqing, Shenyang, Haerbin,Jinan,Zhengzhou, Changsha and Nanning. The contents of energy, protein, fat, carbohydrate, sodium and the percentages of low-fat and low-sodium foods were compared among 7 different kinds of foods including baked foods, convenient foods, leisure foods, puffed foods, milk, beverages and seasonings.

RESULTS871 kinds of pre-packaged foods were collected. The median (min, max) of energy contents of puffed foods, baked foods and leisure foods were 2 155(1 638-2 785) kJ/100 g, 1 980 (582-2 639) kJ/100 g, 1 575 (353-3 015) kJ/100 g respectively. The median (min, max) of fat contents of puffed foods, baked foods and leisure foods were 30.0 (5.0-40.9) g/100 g, 20.5 (0.3-40.5) g/100 g, 15.1 (0-71.4) g/100 g respectively. The contents of carbohydrate of baked foods, convenient foods and puffed foods were high relatively, the medians (min, max) of which were 58.1(19.8-82.5), 56.5(0-90.7), and 56.1(42.6-75.8)g/100 g respectively. The sodium content of seasoning was the highest, which was 2 177 (20-12 000) mg/100 g. The protein content of beverage was the lowest, which was 0.4(0-17.8)g/100 ml.

CONCLUSIONThe energy and fat contents of puffed foods, baked foods and leisure foods were high. The carbohydrate contents of baked foods, convenient foods and puffed foods were high relatively. The sodium content of seasonings was high. The protein contents of beverages were low.

PURPOSE: The purpose of the study was to identify teacher's knowledge about sodium, dietary behaviors related to sodium, attitudes towards a low-salt diet, and meal attitude guidance as well as examine the relationship between these variables. METHODS: The participants were 351 teachers at an elementary school in the Jeonbuk area. The data were analyzed using ANOVA, Duncan test, and Pearson correlation coefficients with SPSS v. 20.0. RESULTS: The score for teachers' knowledge about sodium was 12.92 points of a possible 16, the score for dietary behavior related to sodium was 46.85 points of a possible 70, and the score for attitude towards a low-salt diet was 33.63 points of a possible 50. Their score for meal attitude guidance was 59.95 points of a possible 80. The knowledge showed significant differences by hypertension drug (p < 0.05) and stress level (p < 0.05). The dietary behavior of sodium use showed significant differences by gender (p < 0.01), work experience (p < 0.05), BMI (p < 0.01), drinking (p < 0.05), concern about health (p < 0.05), and stress level (p < 0.05). The attitude towards a low-salt diet showed significant differences by gender (p < 0.05), marital status (p < 0.05), work experience (p < 0.05), drinking (p < 0.05), concern about health (p < 0.001), and stress level (p < 0.05). Meal attitude guidance showed a significant difference by marital status (p < 0.001), age (p < 0.001), work experience (p < 0.001), drinking (p < 0.01), regularity of health checkup (p < 0.001), concern about health (p < 0.001), and stress level (p < 0.05). There was a low positive correlation between knowledge about sodium and dietary behavior related to sodium as well as between dietary behavior related to sodium and attitudes towards a low-salt diet. Attitudes towards a low-salt diet showed a positive correlation with meal attitude guidance. CONCLUSION: Therefore, it is necessary to consider educational programs on increasing knowledge and attitudes towards a low-salt diet in teachers for improvement of meal attitude guidance activities for students.
