Urban African-American youth, aged 15-19 years, have asthma fatality rates that are higher than in whites and younger children, yet few programs target this population. Traditionally, urban youth are believed to be difficult to engage in health-related programs, both in terms of connecting and convincing.
Develop and evaluate a multimedia, web-based asthma management program to specifically target urban high school students. The program uses "tailoring," in conjunction with theory-based models, to alter behavior through individualized health messages based on the user's beliefs, attitudes, and personal barriers to change.
High school students reporting asthma symptoms were randomized to receive the tailored program (treatment) or to access generic asthma websites (control). The program was made available on school computers.
Functional status and medical care use were measured at study initiation and 12 months postbaseline, as were selected management behaviors. The intervention period was 180 days (calculated from baseline). A total of 314 students were randomized (98% African American, 49% Medicaid enrollees; mean age, 15.2 yr). At 12 months, treatment students reported fewer symptom-days, symptom-nights, school days missed, restricted-activity days, and hospitalizations for asthma when compared with control students; adjusted relative risk and 95% confidence intervals were as follows: 0.5 (0.4-0.8), p = 0.003; 0.4 (0.2-0.8), p = 0.009; 0.3 (0.1-0.7), p = 0.006; 0.5 (0.3-0.8), p = 0.02; and 0.2 (0.2-0.9), p = 0.01, respectively. Positive behaviors were more frequently noted among treatment students compared with control students. Cost estimates for program delivery were $6.66 per participating treatment group student.
A web-based, tailored approach to changing negative asthma management behaviors is economical, feasible, and effective in improving asthma outcomes in a traditionally hard-to-reach population.
15至19岁的城市非裔美国青年哮喘死亡率高于白人及年幼儿童,但针对该人群的项目却很少。传统上,人们认为城市青年在参与健康相关项目方面存在困难,无论是在联系还是说服方面。
开发并评估一个专门针对城市高中生的多媒体网络哮喘管理项目。该项目采用“个性化定制”,结合基于理论的模型,通过根据用户的信念、态度和个人改变障碍提供个性化健康信息来改变行为。
报告有哮喘症状的高中生被随机分为接受个性化定制项目(治疗组)或访问一般哮喘网站(对照组)。该项目可在学校电脑上使用。
在研究开始时和基线后12个月测量功能状态和医疗保健使用情况,以及选定的管理行为。干预期为180天(从基线开始计算)。共有314名学生被随机分组(98%为非裔美国人,49%为医疗补助计划参保者;平均年龄15.2岁)。在12个月时,与对照组学生相比,治疗组学生报告的症状天数、症状夜晚数、缺课天数、活动受限天数和哮喘住院次数更少;调整后的相对风险和95%置信区间如下:分别为0.5(0.4 - 0.8),p = 0.003;0.4(0.2 - 0.8),p = 0.009;0.3(0.1 - 0.7),p = 0.006;0.5(0.3 - 0.8),p = 0.02;0.2(0.2 - 0.9),p = 0.01。与对照组学生相比,治疗组学生更频繁地出现积极行为。每个参与治疗组学生的项目实施成本估计为6.66美元。
一种基于网络的、个性化定制的改变哮喘管理负面行为的方法在改善传统上难以接触人群的哮喘结局方面经济、可行且有效。
