To investigate the longitudinal impacts of pubertal timing and weight status on Internet use in adolescents.
Three waves of data on a longitudinal cohort of 7th grade students (N = 2430) were retrieved from the Taiwan Youth Project. Univariate and multivariate regression models were applied using crude and adjusted odds ratios (OR) with 95% confidence intervals (CI) to examine the concomitant impacts of pubertal timing and weight status on adolescent Internet use.
The dataset identified 210 (8.7%) students using the Internet for more than 20 hours/week, and 81 (3.3%) were viewing pornographic material online. Early maturing and thin-weight adolescents were at 35% and 46% increased risks of spending long hours on Internet use, respectively. While early puberty was associated with online pornography viewing among males (adjusted OR 1.84, 95% CI 1.04-3.28), early puberty was contrarily a protective factor against online gaming in females (adjusted OR 0.59, 95% CI 0.36-0.96).
Early puberty was found to be positively related to adolescent Internet use. Appropriate health education and guidance regarding Internet use should be provided to those with different developing needs.
探讨青春期发育时间和体重状况对青少年互联网使用的纵向影响。
从台湾青少年项目中获取了三批关于 7 年级学生的纵向队列数据（N=2430）。使用未调整和调整后的优势比（OR）及 95%置信区间（CI），通过单变量和多变量回归模型，考察青春期发育时间和体重状况对青少年互联网使用的共同影响。
该数据集确定了 210 名（8.7%）学生每周上网超过 20 小时，81 名（3.3%）学生在线观看色情材料。早熟和消瘦的青少年分别有 35%和 46%的风险增加长时间上网的风险。虽然青春期提前与男性在线观看色情内容有关（调整后的 OR 为 1.84，95%CI 为 1.04-3.28），但青春期提前对女性在线游戏是一个保护因素（调整后的 OR 为 0.59，95%CI 为 0.36-0.96）。
青春期提前与青少年互联网使用呈正相关。对于具有不同发展需求的青少年，应提供关于互联网使用的适当健康教育和指导。
