摘要
目的了解山东大学区机关事业单位老年人群维生素D营养状况。方法在本院公费医疗单位分层随机抽取老年人564例，年龄60～91岁，平均（69．5±6．5）岁。将564例入选者分为60～74岁组和≥75岁组。采用酶联免疫吸附法测定血25－羟维生素D（25（0H）D2水平，据此确定维生素D营养状况。应用SPSS13．0软件进行统计分析。结果≥75岁组老年人维生素D营养缺乏、不足、临界和充足所占比例分别为9．8％、53．0％、27．3％和9．8％，与60～74岁组（5．3％、38．0％、33．3％、23．4％）比较，差异有统计学意义（χ2＝19．097，P〈0．01）。女性维生素D缺乏及不足所占比率较男性高，差异有统计学意义（χ2＝11．445，P〈0．01）。结论山东大学区机关事业单位老年人群普遍存在维生素D缺乏及不足，且随着年龄的增加更加显著，女性较为严重。
Objective To study the vitamin D nutritional status in the elderly people from organs and institutions in Jinan urban district. Methods 564 cases were available from institutions enioying a public medical care in Qianfoshan Hospital by stratified random sampling. The subjects aged （69.5±6.5）years were divided into two groups.. 60-74 years and ≥75 years. The [25（OH）D] levels was measured by enzyme-linked immunosorbent assay （ELISA）. It was defined that [25 （OH） D] levels ≥ 75 nmol/L was sufficient, 50.0-74.9 nmol/L was critical, 25.0-49.9 nmol/L were insufficient and 〈25 nmol/L was deficient. All data processing and statistical analysis were finished by SPSS13.0. Results The numbers of sufficient, critical, insufficient and deficient vitamin D in 564 subjects were 114（20.2%）, 180（31.9%）, 234（41.5%） and 36（6.4%）, in subjects aged ≥75 years were 13（9.8%）, 36（27.3%）, 70（53.0%） and 13（9.8%）, and in subjects aged 60-74 years were 101 （23.4%）, 144 （33.3%）, 164 （38.0%）, 23 （5.3%）, respectively. There was significant difference in the vitamin D nutritional status between the two age groups （χ2= 19. 097,P〈0.01）. The numbers of sufficient, critical, insufficient and deficient vitamin D in the 246 male were 57 （23.2%）, 91（37.0%）, 86 （35.0%） and 12（4.9%）, in the 318 female were 57（17.9%）, 89 （28.0%）, 148（46.5%） and 24（7.5%）. The percentages of insufficient and deficient vitamin D in the female were higher than in the male （χ2 =11. 445 ,P〈0.01）. Conclusions Insufficient and deficient vitamin D nutritional states are common in the elderly people from organs and institutions in Jinan urban district and are increasing with age, especially in the female.
