To evaluate the effectiveness of an educational video on osteoporosis at increasing knowledge and preventive health behaviors.
A total of 195 women between 35 and 80 years of age without documented osteopenia or osteoporosis, who presented for a gynecological examination in an outpatient setting, were enrolled. Of this number, 98 women were randomly assigned to the intervention group that viewed the video before their office visit, and 97 women were assigned to a control group and saw their physician in a routine manner. After their visit, all participants answered a questionnaire that assessed their knowledge of osteoporosis and baseline health-related behaviors. Three months later, a follow-up questionnaire was mailed to participants, eliciting whether preventive behavior had commenced. Frequencies were compared using the Fisher exact test (2-tailed). Continuous variables were analyzed using the Student's t test.
The two groups had no statistically significant differences in demographics. The intervention group scored a mean of 92% compared with a mean of 80% in the control group on the initial osteoporosis assessment questionnaire (P < 0.001). The 3-month follow-up questionnaire demonstrated that significantly more women in the intervention group started taking calcium supplements (26.5% v 4.9%; P < 0.001), started taking vitamin D supplements (20.6% v 6.6%; P = 0.02), started a program of weight-bearing exercise (13.3% v 1.7%; P = 0.03), and started hormone therapy (8% v 1%; P = 0.04).
The use of an educational video on osteoporosis seems to improve patient knowledge and may positively impact health-related behaviors.
评估一部关于骨质疏松症的教育视频在增加知识和促进预防保健行为方面的效果。
招募了195名年龄在35至80岁之间、无骨质疏松或骨质减少记录的女性，她们在门诊接受妇科检查。其中，98名女性被随机分配到干预组，在就诊前观看视频；97名女性被分配到对照组，按常规方式看医生。就诊后，所有参与者都回答了一份问卷，评估她们对骨质疏松症的知识和基线健康相关行为。三个月后，向参与者邮寄了一份随访问卷，询问是否开始了预防行为。使用Fisher精确检验（双侧）比较频率。连续变量使用学生t检验进行分析。
两组在人口统计学方面无统计学显著差异。在初始骨质疏松症评估问卷上，干预组的平均得分是92%，而对照组为80%（P < 0.001）。3个月后的随访问卷显示，干预组中开始服用钙补充剂的女性显著更多（26.5%对4.9%；P < 0.001），开始服用维生素D补充剂的女性显著更多（20.6%对6.6%；P = 0.02），开始进行负重锻炼计划的女性显著更多（13.3%对1.7%；P = 0.03），开始激素治疗的女性显著更多（8%对1%；P = 0.04）。
使用关于骨质疏松症的教育视频似乎能提高患者知识，并可能对健康相关行为产生积极影响。
