SHS Treatment for Postpartum African American Smokers

描述(由申请人提供)：在美国，每天有超过1900万儿童暴露在二手烟(SHS)中。婴儿最容易受到SHS的伤害，对于五岁以下的儿童来说，暴露于SHS导致的死亡比所有儿童意外伤害的总和还要多。为了响应2010年健康人目标和NCI优先事项，这项试验旨在减少服务不足的城市非裔美国人(AA)人群中婴儿SHS的暴露，同时在产后(PP)母亲中促进戒烟。这项拟议的为期16周的试验名为“Philadelphia Fresh(建立无烟家庭的家庭规则)”，将450名两岁以下儿童的PP母亲随机分成两组。被随机接受多模式个性化治疗(MIT)的母亲将获得1。)儿科医生建议，2。)两次密集的、以家庭为中心的家庭行为咨询会议。一份对文化敏感的治疗手册分四个部分邮寄，从第一周和第四周开始每两周一次。)七次后续电话咨询会议。标准护理控制(SCC)组的母亲将接受儿科医生的评估、建议和一本全面的自助手册，其中包含关于SHS及其减少、戒烟和预防复发的信息。我们预测，通过12个月的随访，MIT组将比SCC组表现出更好的婴儿SHS暴露和母亲吸烟结果(通过自我报告、婴儿尿可替宁和母亲唾液可替宁来衡量)。我们的试验还将通过纳入治疗成分来测试社会支持、婴儿对SHS的易感性以及对吸烟结果的负面影响，以增强和维持自然的母体支持系统，增加对SHS风险和减少SHS的好处的知识，并改善情绪管理。我们假设这些变量的改善将对治疗结果产生积极影响。最后，我们的试验将测试基线体重担忧和抑郁症状的缓解效果。我们假设基线体重担忧和抑郁对结果的主要影响以及交互作用：与SCC相比，基线体重担忧和抑郁程度更高的母亲在MIT的结局会更好。我们将使用GEE分析来检验假设的吸烟行为在基线、8周、16周(EOT)、3个月和12个月随访时间点的变化，并探索缓和变量的影响。通径分析将检验中介变量对结果的影响。

DESCRIPTION (provided by applicant): More than 19 million children in the U.S. are exposed to second-hand smoke (SHS) on a daily basis. Infants are the most susceptible to SHS harm, and for children under five, SHS exposure causes more deaths than all unintentional childhood injuries combined. In response to Healthy People 2010 goals and NCI priorities, this trial aims to reduce infant SHS exposure in an under-served urban African American (AA) population while simultaneously promoting smoking cessation among the postpartum (Pp) mothers. The proposed 16-week trial, "Philadelphia FRESH (Family Rules for Establishing Smoke-free Homes)," will randomize 450 Pp mothers of children up to two years old into two treatment groups. Mothers randomized to the multimodal, individualized treatment (MIT) will receive 1.) pediatrician advice, 2.) two intensive, family-centered, in-home behavioral counseling sessions, 3.) a culturally-sensitive treatment manual mailed in four sections, biweekly starting week 1, and 4.) seven follow-up phone counseling sessions. Mothers in the standard care control (SCC) group will receive pediatrician assessment, advice, and one comprehensive self-help manual with information on SHS and its reduction, smoking cessation, and relapse prevention. We predict that through 12-month follow-up, the MIT group will demonstrate better infant SHS exposure and maternal smoking outcomes (measured by self-report, infant urine cotinine, and maternal saliva cotinine) than the SCC group. Our trial will also test the mediating influence of social support, perceived infant vulnerability to SHS, and negative affect on smoking outcomes by incorporating treatment components to boost and sustain natural maternal support systems, increase knowledge of SHS risks and benefits of SHS reduction, and improve mood management. We hypothesize that improvements in these variables will positively impact treatment outcome. Finally, our trial will test the moderating effects of baseline weight concerns and depression symptoms. We hypothesize a main effect for baseline weight concerns and depression on outcomes, as well as an interaction: moms with greater baseline weight concern and depression will have better outcomes in MIT compared to SCC. We will use GEE analysis to test hypothesized smoking behavior changes across baseline, 8-week, 16-week (EOT), 3-mo and 12-month follow-up time points and explore the influence of moderating variables. Path analysis will test mediating variables' influence on outcomes.
