山西省太谷县服务业人群血清硒状况研究

Study on serum selenium level of people in service sectors in Taigu County,Shanxi Province

目的测定非缺硒地区成年居民血清硒水平。方法从参加体检的山西省太谷县服务业从业人员中随机抽取793名,采用荧光分光光度法测定其血清硒含量,并收集性别、年龄、职业、文化程度信息,进行数据统计分析处理和组间血清硒比较。结果全人群(年龄20～67岁)、男性和女性平均血清硒含量分别为(0.0913±0.0186)、(0.0947±0.0184)和(0.0887±0.0184)μg/ml,男性血清硒显著高于女性。按照年龄、职业和文化程度分组进行比较,发现不同组间血清硒差异没有统计学意义。将各年龄组男女血清硒进行对比分析,发现20～29岁组、30～39岁组内男性血清硒显著高于女性,大于40岁各组男女血清硒差异没有显著性;30～39岁男性血清硒最高,而女性却最低;40岁以后男性血清硒有所降低,而女性血清硒增加较多。结论太谷县成人居民并不缺硒,但与在国际上发达地区人群硒营养水平相比仍然处于中等偏下水平;20～40岁人群男性血清硒水平显著高于女性,40岁以后男女间血清硒差异变小。

Objective To detect serum selenium level of people in non-selenium-deficiency region. Methods A total of 793 subjects were recruited by random sampling from people engaged in service sectors in Taigu county, Shanxi province. Information about gender,age,occupation and educational level were collected and the content of serum selenium was measured by fluorospectrophotometry. All data were statistically analyzed with SPSS software version 13. 0. Results The age distribution for these samples ranged from 20 to 67 years old. Their average serum selenium level and standard deviation （ SD） were （ 0. 0913 ± 0. 0186 ） μg /ml,（ 0. 0947 ± 0. 0184 ） μg /ml and （0. 0887 ± 0. 0184）μg/ml for total,male and female,respectively,and the level of male was significantly higher than that of female. There were no significant differences of serum selenium in each group of different ages, occupation,and educational level. Serum selenium in male were significantly higher than in female in both 20 - 29 years old group and 30 - 39 years old group,but there were no significant differences in groups older than 40. In 30 - 39 years old group,male had the highest serum selenium,but female occurred just the opposite. There was a decrease of serum selenium in male older than 40,but a great increase in female. Conclusion The serum selenium level of adults in this area was adequate,but compared with progressed areas in the world,it could be categorized as low-middle level,serum selenium in male of 20 - 40 years old was significantly higher than in female,but thedifferences turn to be narrow in people older than 40 years old.
