Abstract

BACKGROUND

Cardiovascular disease remains the leading killer of women in most developed areas of the world. Rates of physical inactivity and poor nutrition, which are two of the most important modifiable risk factors for cardiovascular disease in women, are substantial. This study sought to examine the effectiveness of a community-based lifestyle-modification program on increasing women's physical activity in a randomized trial guided by community-based participatory research (CBPR) methods.

METHODS

A total of 335 healthy, 25-64 years old women who had been selected by a multiple-stage stratified cluster random sampling method in Bushehr Port/I.R. Iran, were randomized into control and intervention groups. The intervention group completed an 8-week lifestyle modification program for increasing their physical activity, based on a revised form of Choose to Move program; an American Heart Association Physical Activity Program for Women. Audio-taped activity instructions with music and practical usage of the educational package were given to the intervention group in weekly home-visits by 53 volunteers from local non-governmental and community-based organizations.

RESULTS

Among the participants, the percentage who reported being active (at lease 30 minutes of moderate intensity physical activity for at least 5 days a week, or at least 20 minutes of vigorous physical activity for at least three days a week) increased from 3% and 2.7% at baseline to 13.4% and 3% (p < 0.0001) at the ending of the program in the intervention and control groups, respectively. The participants in the intervention group reported more minutes of physical activity per week (mean = 139.81, SE = 23.35) than women in the control group (mean = 40.14, SE = 12.65) at week 8 (p < 0.0001). The intervention group subjects exhibited a significantly greater decrease in systolic blood pressure (-10.0 mmHg) than the control group women (+2.0. mmHg). The mean ranks for posttest healthy heart knowledge in the intervention and control groups were 198.91 and 135.77, respectively (P < 0.0001).

CONCLUSION

An intervention based on CBPR methods can be effective for the short-term adoption of physical activity behavior among women. The development of participatory process to support the adequate delivery of lifestyle-modification programs is feasible and an effective healthcare delivery strategy for cardiovascular community health promotion.

摘要

背景

在世界上大多数发达地区，心血管疾病仍是女性的主要死因。身体活动不足和营养状况不佳是女性心血管疾病最重要的两个可改变风险因素，其发生率很高。本研究旨在通过一项以社区参与性研究（CBPR）方法为指导的随机试验，检验一项基于社区的生活方式改变项目对增加女性身体活动的有效性。

方法

通过多阶段分层整群随机抽样方法，在伊朗布什尔港共选取了335名年龄在25 - 64岁之间的健康女性，随机分为对照组和干预组。干预组基于修订版的“选择行动”项目（美国心脏协会女性身体活动项目），完成了一项为期8周的旨在增加身体活动的生活方式改变项目。来自当地非政府组织和社区组织的53名志愿者每周进行家访，向干预组提供带有音乐的活动指导录音带以及教育包的实际使用指导。

结果

在参与者中，报告有身体活动的百分比（每周至少5天进行至少30分钟中等强度身体活动，或每周至少3天进行至少20分钟剧烈身体活动）在干预组和对照组中分别从基线时的3%和2.7%增加到项目结束时的13.4%和3%（p < 0.0001）。在第8周时，干预组参与者报告的每周身体活动分钟数（均值 = 139.81，标准误 = 23.35）多于对照组女性（均值 = 40.14，标准误 = 12.65）（p < 0.0001）。干预组受试者的收缩压下降幅度（-10.0 mmHg）显著大于对照组女性（+2.0 mmHg）。干预组和对照组在测试后健康心脏知识的平均秩分别为198.91和135.77（P < 0.0001）。
