RESUMO
Objective @#To understand the current situation and influencing factors of occupational burnout among vaccination personnels in Haining.@*Methods @#The vaccination staffs of all vaccination clinics in Haining were investigated by the general questionnaire and Maslach Burnout Inventory. Logistic regression model was used to analyze the influencing factors for job burnout of vaccination personnels. @*Results @#A total of 160 questionnaires were distributed and 158 valid questionnaires were collected. The effective rate of questionnaires was 98.75%. A total of 91 vaccination staffs suffered from occupational burnout,accounting for 57.59%. Among them,the median（inter-quartile range）of the scores of emotional exhaustion,depersonalization and personal achievement were 13.00（14.00）,4.00（6.00）and 26.50（17.00）,respectively,which were all lower than the normalized scores（22.19,7.12 and 36.53,P<0.05）. The results of logistic regression analysis showed that having confidence in vaccination was a protective factor for emotional failure（OR=0.175,95%CI：0.058-0.523）and low sense of achievement（OR=0.272,95%CI：0.079-0.937）in vaccination personnels;having experience in adverse event following immunization（AEFI）was a risk factor for depersonalization（OR=3.125,95%CI：1.472-6.633）and occupational burnout（OR= 2.391,95%CI：1.189-4.807）in vaccination personnels. @*Conclusion @#A certain proportion of vaccination staffs in Haining suffered from occupational burnout. The experience of AEFI was a risk factor for their occupational burnout.
RESUMO
Objective To evaluate the effects of preventive and control measures on iodine deficiency disorders (IDD) in Hanning City in 2009-2014,we investigated the status of iodine nutrition level and IDD.Methods The wholesale salt was sampled irregularly for salt iodine test yearly in Haining City,Zhejiang Province.In the investigation,a random sampling was carried out as following:in 2009-2011,2 towns were selected from each of the east,west,south,north areas of the city,1 town was selected from the middle area of the city,4 villages were selected from each town,and edible salt samples were collected in 8 households from each village.However,in the year of 2012-2014,only 1 town was selected from 5 areas (east,west,south,north,middle) of the city,still 4 villages were selected from each town,and then edible salt samples were collected in 15 households from each village.A central primary school was selected in each sampled town,at least 40 students aged 8-l0 years old were selected for detection of thyroid volume,and at least 20 of these students' instant urine samples were collected for detecting urinary iodine.Salt iodine was tested using direct titration method,thyroid volume was measured by palpation method;urinary iodine was tested using arsenic cerium catalytic spectrophotometry.Results A total of 339 wholesale salt samples were tested,the median of salt iodine was 25.08-32.64 mg/kg in 2009-2013,and all the sampled wholesale salt samples were found to be qualified.A total of 1 764 household salt samples were collected in 2009-2014,the median of salt iodine was 23.40-28.15 mg/kg,and the consumption rates of qualified iodized salt were all higher than 90％ each year.Monitoring results of 1241 children aged 8-10 years old showed the goiter rates were all equal or lower than 2％,urinary iodine medians were 102.5-210.5 μg/L in 708urine samples,the proportion of urinary iodine under 50 μg/L was less than 20％,while the urinary iodine proportion in appropriate level in 100-＜ 200μg/L rose significantly over the last two years.Conclusions Measures with iodized salt as the principal way have good effects in Haining.However,the government needs to strengthen the regulation of salt industry market in the future to prevent unqualified salt come into the market.
