Smoking and overweight or obesity are preventable causes of disease and death. Women are reluctant to quit smoking because of concerns about postcessation weight gain, underscoring the need to elucidate patterns of weight concerns and associated psychosocial factors that may affect smoking cessation outcomes. The present study aimed to subtype women smokers based on psychosocial and behavioral factors associated with smoking and weight, and examine the utility of these subtypes to predict abstinence and postcessation weight gain.
Weight-concerned women (N = 343) were randomized to 1 of 2 smoking cessation counseling adjuncts and 1 of 2 cessation medication conditions. At baseline, women were weighed and completed measures of depression, weight or appearance concerns, and eating behaviors. At 3-, 6-, and 12-months after the target quit date, women were weighed and completed self-report and biochemical smoking assessments.
Latent profile (LP) analyses supported a 3-profile model. The groups had typical (53%, LP1), minimal (33%, LP2), and high (14%, LP3) levels of depressive symptoms and weight concerns. At 12-months posttarget quit date, women in LP3 were more likely to relapse than women in LP1 (odds ratio, OR = 2.93). Among abstinent women, those in LP2 and LP3 gained more postcessation weight than those in LP1.
Heterogeneity in symptoms of depression, weight or appearance concerns, and eating behaviors was captured by three groups of women smokers, with unique risks for relapse and postcessation weight gain. The distinct profiles identified may help personalize the delivery of care for smoking cessation and, ultimately, reduce disease risk. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
吸烟和超重或肥胖是可预防的疾病和死亡原因。女性不愿意戒烟是因为担心戒烟后体重增加，这突显出需要阐明与吸烟和体重相关的担忧模式以及可能影响戒烟结果的相关心理社会因素。本研究旨在根据与吸烟和体重相关的心理社会和行为因素对女性吸烟者进行亚型分类，并研究这些亚型对预测戒烟成功和戒烟后体重增加的作用。
体重担忧的女性（N=343）被随机分配到 2 种戒烟咨询辅助方法和 2 种戒烟药物条件之一。在基线时，女性被称重并完成抑郁、体重或外貌担忧以及饮食行为的测量。在目标戒烟日期后的 3、6 和 12 个月，女性被称重并完成自我报告和生物化学吸烟评估。
潜在剖面（LP）分析支持 3 种模型。这些组具有典型（53%，LP1）、最低（33%，LP2）和最高（14%，LP3）水平的抑郁症状和体重担忧。在 12 个月的目标戒烟日期后，LP3 组的女性比 LP1 组的女性更有可能复发（优势比，OR=2.93）。在戒烟的女性中，LP2 和 LP3 组在戒烟后体重增加比 LP1 组更多。
抑郁症状、体重或外貌担忧和饮食行为的异质性由三组女性吸烟者所表现出，这三组女性具有独特的复发和戒烟后体重增加的风险。所确定的不同特征可能有助于为戒烟提供个性化护理，最终降低疾病风险。
