Improved bone health during adolescence can have lifelong implications, reducing the risk of bone fragility.
This study aims to evaluate the effectiveness of an e-book in increasing knowledge about and promoting healthy practices related to bone health among Malay adolescents in Kuala Lumpur, Malaysia.
A total of 72 adolescents (female: n=51, 71%; age: mean 15, SD 0.74 y) were recruited from selected secondary schools. The participants answered a pretest web-based questionnaire on sociodemographic data, knowledge about osteoporosis, and physical activity. A video call was conducted to assess dietary calcium intake. Participants were provided with a link to an e-book on bone health and instructed to read it within 2 weeks. Postintervention assessments included those for knowledge, physical activity, dietary calcium intake, and acceptance of the e-book.
There was a significant increase in the median knowledge score, which was 40.6% (IQR 31.3%-46.9%) during the pretest and 71.9% (IQR 53.9%-81.3%) during the posttest (P<.001). However, no changes were observed in dietary calcium intake or physical activity levels. Most participants did not meet the recommended calcium requirements (61/62, 98%) and exhibited sedentary behavior (pretest: 51/62, 82%; posttest: 48/62, 77%). The e-book, however, was well accepted, with the majority reporting that they understood the contents (70/72, 97%), liked the graphics (71/72, 99%), and approved of the layout (60/72, 83%) and font size (66/72, 92%) used.
The developed e-book effectively increases knowledge levels related to bone health and is well accepted among participants. However, this educational material did not improve bone health practices. Additional strategies are necessary to bridge the gap between knowledge and behavior change.
青春期骨骼健康状况的改善会产生终身影响，降低骨骼脆弱的风险。
本研究旨在评估一本电子书在增加马来西亚吉隆坡马来青少年对骨骼健康的了解并促进其相关健康行为方面的有效性。
从选定的中学招募了72名青少年（女性：n = 51，占71%；年龄：平均15岁，标准差0.74岁）。参与者回答了一份基于网络的预测试问卷，内容包括社会人口统计学数据、骨质疏松症知识和身体活动情况。通过视频通话评估膳食钙摄入量。为参与者提供了一本关于骨骼健康的电子书链接，并要求他们在两周内阅读。干预后的评估包括对知识、身体活动、膳食钙摄入量以及电子书接受度的评估。
中位数知识得分显著提高，预测试时为40.6%（四分位间距31.3% - 46.9%），后测试时为71.9%（四分位间距53.9% - 81.3%）（P <.001）。然而，膳食钙摄入量或身体活动水平未观察到变化。大多数参与者未达到推荐的钙需求量（61/62，98%），且表现出久坐行为（预测试：51/62，82%；后测试：48/62，77%）。然而，这本电子书很受欢迎，大多数人报告他们理解了内容（70/72，97%），喜欢图表（71/72，99%），并认可所使用的布局（60/72，83%）和字体大小（6,6/72，92%）。
所开发的电子书有效提高了与骨骼健康相关的知识水平，且在参与者中很受欢迎。然而，这种教育材料并未改善骨骼健康行为。需要额外的策略来弥合知识与行为改变之间的差距。
