在拉丁裔成人中，外展信息的数量和金钱激励对戒烟治疗参与度的影响如何？

study_design_and_methods

This pragmatic randomized clinical trial used a 3 × 2 factorial design.

这项实用的随机临床试验采用了3×2析因设计。

The first factor, monetary incentives, comprised 3 conditions: (1) receiving a small fixed amount ($5.00) when enrolling, (2) receiving a chance to win a large amount ($200.00) when enrolling, and (3) no monetary incentive when enrolling.

第一个因素是金钱激励，包括3种情况：（1）在登记时获得一小笔固定金额（5.00美元），（2）在登记时获得赢得一大笔金额（200.00美元）的机会，以及（3）在登记时没有金钱激励。

The second factor, number of cycles, comprised 2 conditions: (1) 1 cycle of messages and (2) 4 cycles of messages.

第二个因素，即周期数，包括2种情况：（1）1个周期的信息传递和（2）4个周期的信息传递。

Latino adults who smoke (n = 2,826) were identified in electronic medical records.

在电子病历中识别出吸烟的拉丁裔成人（n = 2,826）。

Participants were randomized in a 1:1:1 ratio to receive 1 of 3 monetary incentive conditions and in a 1:2 ratio to receive 1 or 4 cycles of messages.

参与者按1:1:1的比例随机分配到三种金钱激励条件之一，并按1:2的比例随机接受1个周期或4个周期的消息干预。

The main outcome was enrollment in a smoking cessation text messaging intervention.

主要结果是参与戒烟短信干预计划的登记情况。

Results

Enrollment rates ranged from 1.3% for the group that received no monetary incentive for enrollment and 1 cycle of messages to 5.4% for the group that received a fixed amount for enrollment and 4 cycles of messages.

入组率从接受无金钱激励和1个周期信息的组的1.3%到接受固定金额入组费和4个周期信息的组的5.4%不等。

Receiving 4 cycles of messages was associated with a higher likelihood of enrollment compared with receiving 1 cycle of messages (OR, 1.92 [95% CI, 1.22-3.01]; P < .01).

接受4个周期的信息与接受1个周期的信息相比，与更高的入组可能性相关（OR，1.92 [95% 置信区间，1.22-3.01]；P < .01）。

Monetary incentives were not associated with enrollment.

金钱激励与入组之间没有关联。

interpretation

Among Latino adults, enrollment in smoking cessation treatment increased significantly with an increasing number of cycles.

在拉丁裔成年人中，随着周期数的增加，戒烟治疗的入组率显著提高。

In contrast, monetary incentives did not increase enrollment.

相比之下，金钱激励并未增加入组率。

Although modest, the 5.3% enrollment rate found among participants who received 4 cycles of messages and no monetary incentive can inform future population-level efforts to advance smoking cessation among Latino adults.

尽管入组率仅为5.3%，但接受4轮信息推送且无金钱激励的参与者所显示出的入组率，可以为未来在拉丁裔成人中推进戒烟的人群水平努力提供参考。
