This study assessed the effects of the Health Works for Women (HWW) intervention on improving multiple behaviors including nutrition and physical activity among rural female blue-collar employees in North Carolina.
Nine small to mid-size workplaces were randomly assigned to either intervention or delayed intervention conditions. After a baseline survey, an intervention consisting of two computer-tailored magazines and a natural helpers program was conducted over 18 months. Delayed worksites received one tailored magazine. Approximately 77 and 76% of baseline respondents completed follow-up surveys at 6 and 18 months, respectively, and 538 women (63%) completed all three surveys.
At the 18-month follow-up, the intervention group had increased fruit and vegetable consumption by 0.7 daily servings compared to no change in the delayed group (P < 0.05). Significant differences in fat intake were observed at 6 months (P < 0.05) but not at 18 months. The intervention group also demonstrated improvements in strengthening and flexibility exercise compared to the delayed group. The rates of smoking cessation and cancer screening did not differ between study groups.
The HWW project was a successful model for achieving certain health behavior changes among blue-collar women.
本研究评估了“女性健康行动”（HWW）干预措施对改善北卡罗来纳州农村女性蓝领员工多种行为（包括营养和身体活动）的影响。
九个中小型工作场所被随机分配到干预组或延迟干预组。在基线调查之后，在18个月内开展了一项由两本计算机定制杂志和一个自然辅助计划组成的干预措施。延迟干预的工作场所收到一本定制杂志。分别约有77%和76%的基线受访者在6个月和18个月时完成了随访调查，538名女性（63%）完成了所有三项调查。
在18个月的随访中，干预组的水果和蔬菜摄入量每天增加了0.7份，而延迟干预组没有变化（P < 0.05）。在6个月时观察到脂肪摄入量存在显著差异（P < 0.05），但在18个月时没有。与延迟干预组相比，干预组在力量和柔韧性锻炼方面也有所改善。研究组之间的戒烟率和癌症筛查率没有差异。
“女性健康行动”项目是在蓝领女性中实现某些健康行为改变的成功模式。
