We evaluate the effectiveness of a swim skill acquisition intervention among Latino youths, ages 3-14, a minority population at increased risk of drowning.
Parents were recruited through community institutions to have their children participate in group swim lessons. Each child's swim ability was assessed at baseline, and they were then exposed to swim lessons over an 8-week period, taught by trained professionals. The swim skill curriculum focused on water safety, flotation and endurance, at five levels of increasing skill acquisition. Final swim ability was assessed on the last day of the child's participation. Programme effectiveness was measured using direct pre-post comparisons with and without adjustment for key moderators (age and gender) and a mediator (number of practices). We also present a bias-adjusted estimate comparing low with high practice volume relying on a propensity score analysis.
Among the 149 participating children, average acquisition was 12.3 swim skills (95% CI 10.7 to 14.1). Skill acquisition varied by age category (3-5, 6-9 and 10-14 years) and by gender. We found a strong practice intensity effect, with skill acquisition accelerated for those participating in 10 or more swimming lessons. The propensity-adjusted estimate of the impact of 10 or more compared with 9 or fewer lessons was 8.2 skills (95% CI 4.8 to 11.8).
An 8-week swim intervention is effective at building skills in a community-based sample of Latino children, ages 3-14 years. The number of swimming lessons was a far stronger correlate of skill acquisition than were age or gender.
评估一项针对 3-14 岁拉丁裔青少年游泳技能习得干预的效果，这些青少年是溺水风险增加的少数群体。
通过社区机构招募家长，让他们的孩子参加集体游泳课。在基线评估每个孩子的游泳能力，然后让他们在 8 周的时间内接受由专业人员教授的游泳课程。游泳技能课程侧重于水上安全、漂浮和耐力，分为五个技能习得等级。在孩子参与的最后一天评估最终的游泳能力。通过直接进行干预前后比较（不调整和调整关键调节因素（年龄和性别）和中介因素（练习次数））来衡量计划的有效性。我们还根据倾向评分分析，提供了一个比较低练习量和高练习量的偏差调整估计值。
在 149 名参与的儿童中，平均习得 12.3 项游泳技能（95%置信区间 10.7-14.1）。技能习得因年龄组（3-5 岁、6-9 岁和 10-14 岁）和性别而异。我们发现练习强度有很强的影响，参加 10 次或更多游泳课程的儿童技能习得速度加快。参加 10 次或更多次课程与参加 9 次或更少次课程相比的影响的倾向调整估计值为 8.2 项技能（95%置信区间 4.8-11.8）。
在一个基于社区的拉丁裔儿童样本（3-14 岁）中，为期 8 周的游泳干预措施在技能培养方面是有效的。游泳课程的次数与技能习得的相关性远强于年龄或性别。
