简介：多重行为变化干预措施中常缺少有关吸烟和食用水果、蔬菜的信息，特别是对于高危的蓝领工人。针对建筑工人的恶性肿瘤预防干预措施--健康工具，能有效地、独立地获得戒烟和蔬菜、水果食用习惯改变。本项试验研究含有吸烟和水果、蔬菜食用的干预措施是否能改变吸烟者在这两方面的行为习惯。同时，研究上述2个行为阈中行为变化相关性的可能解释。

    方法：一项临床试验在建筑工人中研究戒烟和水果、蔬菜食用干预措施。本研究对上述试验所得数据进行回顾性研究。采用来自300名参与者的调查数据，回答我们的研究问题：基线状态下吸烟参与者，在干预结束是否成功戒烟，是否增加水果和蔬菜的食用。采用16个小型团体讨论的定量数据来帮助阐述这些结果。

    结果：在健康工具研究中，大部分参与者在干预期间获得戒烟效果，而且水果、蔬菜食用增加。

    结论：本项研究显示含有戒烟和增加水果、蔬菜食用的干预措施能成功诱导高危蓝领工人的多重行为变化。此外，我们的结果也为研究戒烟和增加水果、蔬菜食用为什么有互补作用提供了可能的方向。

Abstract

INTRODUCTION: Few multiple behavior change interventions have addressed tobacco use in conjunction with fruit and vegetable consumption, particularly among high-risk blue-collar workers. Tools for Health, a cancer prevention intervention for construction laborers, was effective in achieving behavior change for smoking cessation and fruit and vegetable consumption separately. This study examines whether addressing smoking and fruit and vegetable consumption was successful in achieving positive change for both behaviors. We also explored possible explanations for the relationship between behavior changes in these 2 behavioral domains.

METHODS: We retrospectively analyzed data from a randomized controlled trial testing a smoking cessation and fruit and vegetable consumption intervention for construction workers. We used survey data from 300 intervention participants to answer our primary research question: Did participants who reported being smokers at baseline successfully quit smoking and increase their fruit and vegetable consumption by the end of the intervention? We used qualitative data from 16 small group discussions to help interpret these results.

RESULTS: Tools for Health participants achieved substantial levels of smoking cessation and increased their fruit and vegetable consumption, concurrently, during the course of the intervention.

CONCLUSION: This study provides evidence that pairing smoking cessation with increasing fruit and vegetable consumption can be successful in a multiple behavior change intervention designed for high-risk blue-collar workers. Further, our findings provide potential directions for examining why this pairing might be complementary.
