摘要
目的 调查河南电业基层３６ 个单位３１６ 名从事脑力劳动者腰椎的骨矿含量。方法 应用美国ＨＯＬＯＧＩＣ公司双能Ｘ 线４５００Ｗ 型骨密度仪，行腰椎前后位和侧位骨矿含量检测，重点分析了腰椎侧位感兴趣区ＢＭＤ。结果 在被检测的３１６ 名脑力劳动者中，腰椎前后位和侧位ＢＭＤ 男女组均于３０～３９ 岁达峰值，以后随年龄增长ＢＭＤ 呈下降趋势，腰椎侧位感兴趣区ＢＭＤ 显著低于腰椎侧位ＢＭＤ，经统计学处理Ｐ＜ ０．００１；轻度骨质疏松３４ 例（占１０．７５％ ）；中度骨质疏松６４ 例（占２０．２５％ ）；重度骨质疏松２５ 例（占７．９１％ ）；总计骨质疏松发生率为３９．９１％ 。结论 腰椎侧位感兴趣区骨矿含量检测能早期反映ＢＭＤ 的变化；分析脑力劳动者骨质疏松原因之一是户外活动和体力劳动相对减少。
Objective\ Bone mineral densities (BMD) of lumbar vertebrae in 316 mental workers of 36 electric power enterprises in Henan were determined. Methods\ BMD of anterior\|posterior and lateral lumbar vertebrae were measured by dual energy X\|ray absorptionmetry with emphasis on BMD of area of interest (ROI) in lumbar vertebrae. Results\ Peak values of BMD of lumbar vertebrae occurred in age group 30\|39 years of both sexes, and BMD gradually diminished with increasing age. Slight osteoporosis (OP) occurred in 64 (20.5%),and severe OP in 25(7.91%), the total OP incidence being 39.9%. Conclusion\ Determination of BMD in ROI of lateral lumbar vertebrae can reveal early change of BMC. OP in mental workers is attributed to rather little outdoor activity and physical labor.
