Iodine nutritional status of residents in coastal areas of Fujian province / 中国地方病学杂志

Objective To investigate the iodine nutritional status of residents in coastal areas of Fujian province,and to provide evidence for effective implementation of preventive strategy of scientific supplying of iodine.Methods In 2009,in Fujian province,6 cities were selected,then one area in every city was selected.A District Office was selected in every area,and then 1 Residents Committee in every District Office was selected.Eleven counties were selected,1 township in each county was selected,and then 1 village in each township was selected.Thirty families were selected in each Residents Committee(village),and then iodine content in household drinking water and salt were tested.The per capita salt intake in the households was calculated using 3 days weighing method.Twenty adults aged 18 to 45 were selected to test their urinary iodine; thirty pregnant and lactating women and 50 children aged 8 to 10 in each street(township ) were selected to test their urinary iodine(UI).Results One hundred and fifty three,30,94,183 and 62 families in coastal cities,inland cities,inland rural areas,coastal rural areas,and coastal mountain areas were surveyed,respectively.The median iodine content of salt was 28.4 - 30.8 mg/kg.The coverage rate of iodized salt and the qualified iodized salt consumption rate were all above 90％ in coastal cities,inland cities,inland rural areas and coastal mountain areas.The coverage rate of iodized salt and the qualified iodized salt consumption rate were 86.9％(159/183) and 83.6％(153/183) in coastal rural areas.In coastal cities,coastal rural areas,inland rural areas,inland cities and coastal mountain areas,258,300,110,160 and 101 children aged 8 - 10 were surveyed,respectively,and the median UI were 191.0,165.6,267.7,269.0 and 161.0 μg/L,respectively.One hundred and one,123,118,63 and 41 adults were surveyed,respectively,and the median UI were 197.6,203.4,174.7,302.8 and 154.9 μg/L,respectively.One hundred and fifty one,181,50,101 and 63 pregnant were surveyed,respectively,and the median UI were 156.5,141.7,116.2,163.0 and 126.2 μg/L,respectively.One hundred and fifty four,184,40,111 and 70 lactating women were surveyed,respectively,and the median UI were 130.3,118.8,110.9,154.6 and 175.9 μg/L,respectively.Conclusions The iodine nutritional level of residents in coastal areas is suitable,and iodine excess does not exists.Coastal areas still need to supply iodized salt.We should be highly concerned about the status of iodine nutrition of pregnant women and put this part of population into routine monitoring.

Study on the public health emergent events in Fujian province in 2004-2007 / 中华流行病学杂志

Objeetive To study the public health emergent events(PHEE)in Fujian province，from 2004 to 2007.Methods Descriptive and analytic methods were Used to analyze the PHEE in Fujian province aecording to the internet.based surveillance reports.Results From 2004 to 2007.there were 304 emergency events being surveyed.Of all the events，there were 7(2.30％)belonged to serious-degree of grade II，57(18.75％)to gradeⅢand 240(78.95％)t0 gradeⅣ，but with no grade I.Results showed that the attack rate in affected population WaS 25.82‰.the mortality rate was 0.08‰and the fatalky rate Was 0.32％.The numbers of emergency events decreased 2.82％on average.each year.A total number of 169(55.60％)events occurred in schools with 71(23.36％)in the countryside.Numbers due to infectious disease-born Was 233(76.64％)including avian flu，cholera and dengue fever were predominant pathogens of the grade II and grade emergency events.57(18.75％)of the events was due to food poisoning.The epi.garph showed that there were two peaks.I.e.in Mar-Apr and Sep.contributed 43.1％to the total number of events.Conclusion Emergency events showed a stable decrease in FujJan province with communicable disease and food poisoning the two major sources and more commonly seen in schools and countryside.We suggest that the government and community pay more attention to the emergency events of avian flu,cholera and dengue fever.

Study on the epidemiology and etiologic agent of Dengue fever outbreaks in Fuzhou in 2004 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.</p><p><b>METHODS</b>Data on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody. The sources of infection were traced by nucleotide sequencing.</p><p><b>RESULTS</b>During the epidemic, 93 cases occured consistently with the region entomoplily growth and decay. The viruses of 6 strains isolated from 10 patients' blood specimens were identified as dengue virus type 1. Phylogenetic evidence suggested that the viral isolate had high genetic relation with the isolates from Kampuchea (DENV-1/KHM/2001; GenBank Accession No. L0904278).</p><p><b>CONCLUSION</b>The epidemic was caused by introduction of patients migrating into Fuzhou.</p>

Study on the timeliness of the notifiable communicable diseases surveillance system in Fujian province, China, 2004 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the timeliness of the notifiable communicable diseases surveillance system in Fujian province.</p><p><b>METHODS</b>Database from the internet based communicable diseases reporting system was used.</p><p><b>RESULTS</b>The 50th percentile of time between the disease diagnosed and report recorded in medical faculties was 1 day in 2004 which was 6 days less than that in 2001 - 2003. The timeliness rate of 0 day was 46.46%, a 2.7 times over that in 2001 - 2003. The timeliness of notifiable communicable diseases surveillance system in different administrative areas, reporting units and on different diseases was significantly different. Time between the disease diagnosed and report recorded was the shortest in those cases reported by hospitals and traditional Chinese medicine(TCM) hospitals at the county level and above, with 50th percentile as 0 day, but the timeliness rate of 0 day was 50.76% with 70.04% of the cases were reported from hospitals and TCM hospitals of county level and above. Length between the disease diagnosed and reported was the longest in those cases recorded by Centers for Disease Control and Prevention(CDCs) with the 50th percentile as 3 days. The source of cases recorded by CDCs came from hospitals at the township level, where there was no connection to internet but the reporting cards had to be sent to local CDCs. Time between the disease being diagnosed and reported was 2 days in those cases reported by hospitals at the township level. 21.21% of cases were recorded by hospitals of township level and CDCs. The 50th percentile of time shown between the reported records and confirmed by CDCs was 4 hours The 24 hour timeliness rate was 63.65%.</p><p><b>CONCLUSION</b>The timeliness of the notifiable communicable diseases surveillance system had been improved significantly after the medical personnel recording the cases directly through internet. Timeliness could be further improved through access to internet at the hospitals of township level, training of staff and better hospital management systems.</p>
