To describe a rural, hospital-based public health intervention program and to evaluate its effectiveness in cardiovascular disease (CVD) risk reduction using cross-sectional studies and a panel study.
A rural population of 158,000 located in New York state comprised the intervention population. A similar but separate population was used for reference. A multifaceted, multimedia 5-year program provided health promotion and education initiatives to increase physical activity, decrease smoking, improve nutrition, and identify hypercholesterolemia and hypertension. To evaluate the effectiveness of the intervention, surveys were conducted at baseline in 1989 (cross-sectional) and at follow-up in 1994-95 (cross-sectional and panel). For cross-sectional studies, a random sample of adults was obtained using a three-stage cluster design. Self-reported and objective risk factor measurements were obtained. Comparison of pre- to post- changes in intervention versus reference populations was done using 2 x 2 randomized block ANOVA, 2 x 2 mixed ANOVA. and extension of the McNemar test.
Smoking prevalence declined (from 27.9% to 17.6%) in the intervention population. Significant adverse trends were observed for high-density lipoprotein cholesterol and triglycerides. Systolic blood pressure was reduced while diastolic blood pressure remained stable. Body mass index increased significantly in both populations.
This rural. 5-year CVD community intervention program decreased smoking. The risk reduction may be attributable to tailoring of a multifaceted approach (multiple risk factors, multiple messages, and multiple population subgroups) to a target rural population. The study period was too short to identify changes in CVD morbidity and mortality.
描述一项以医院为基础的农村公共卫生干预项目,并通过横断面研究和队列研究评估其在降低心血管疾病(CVD)风险方面的有效性。
干预人群为纽约州的15.8万农村人口。使用了一个类似但独立的人群作为对照。一项为期5年的多方面、多媒体项目提供了健康促进和教育举措,以增加身体活动、减少吸烟、改善营养,并识别高胆固醇血症和高血压。为了评估干预的有效性,于1989年进行了基线调查(横断面研究),并于1994 - 1995年进行了随访(横断面研究和队列研究)。对于横断面研究,采用三阶段整群设计获取成年人的随机样本。获取了自我报告和客观的风险因素测量值。使用2×2随机区组方差分析、2×2混合方差分析以及McNemar检验的扩展方法,对干预组和对照组人群干预前后的变化进行比较。
干预人群的吸烟率下降(从27.9%降至17.6%)。高密度脂蛋白胆固醇和甘油三酯出现显著的不良趋势。收缩压降低,而舒张压保持稳定。两组人群的体重指数均显著增加。
这项为期5年的农村CVD社区干预项目降低了吸烟率。风险降低可能归因于针对目标农村人群量身定制的多方面方法(多种风险因素、多种信息和多个人口亚组)。研究期过短,无法确定CVD发病率和死亡率的变化。
