To find out the frequency of osteopenia and associated risk factors among young female students.
This observational, cross-sectional study was conducted at the Dow University of Health Sciences, Karachi, from August 2011 to January 2012, and comprised young female students. Convenient sampling method was used. Age, residence, sun exposure, menstrual status, level of physical activity, exercise, vitamin D, calcium intake were variables of interest. Dual-energy X-ray absorptiometry scan was used to measure bone mineral density on the lumbar spine, hip, femur and distal forearm. SPSS 16 was used for data analysis..
A total of 100(76.9%) students were included in this study. The age range was 20-30 years. Overall,70(70%)participants were osteopenic, while 30(30%) were normal. Age<25 years, living with less exposure to sun, less physical activity and diet low in calcium and vitamin D were common risk factors.
The frequency of osteopenia was significantly high among young female students.
了解年轻女学生中骨质减少的发生率及相关危险因素。
本观察性横断面研究于2011年8月至2012年1月在卡拉奇的道健康科学大学进行，研究对象为年轻女学生。采用方便抽样法。年龄、居住情况、日晒情况、月经状况、身体活动水平、锻炼情况、维生素D、钙摄入量为感兴趣的变量。采用双能X线吸收法扫描测量腰椎、髋部、股骨和前臂远端的骨密度。使用SPSS 16进行数据分析。
本研究共纳入100名（76.9%）学生。年龄范围为20 - 30岁。总体而言，70名（70%）参与者骨质减少，30名（30%）正常。年龄<25岁、日照少、身体活动少以及钙和维生素D含量低的饮食是常见危险因素。
