广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.     

梅县2000～2005年农村饮用水质卫生状况分析

目的查清梅县2000—2005年农村生活饮用水源水质卫生状况，为农村改水防病工作提供科学依据。方法采用定期监测与随机抽样相结合的方法，水源水质按《生活饮用水标准检验方法》（GB5750—85），依《农村实施〈生活饮用水卫生标准〉准则》评价。结果3年共抽查1202例水样，其水源以井水、泉水、河水为主，水质总合格率为62．73％。其中，井水合格率为52．81％，泉水合格率为63．5l％，自来水合格率为94．87％，河水合格率为44．12％。结论梅县水源水质自然本底较好，但农村生活饮用水源水质受到不同程度的自然和人为污染。水源选择、卫生防护等方面还有缺陷。建议加强水源防护及水质净化消毒。
