摘要
目的研究通过社区群组干预改善生活方式对高血压前期人群血压的影响。方法采用社区随机对照试验设计。干预组188人参与群组干预,对照组234人进行常规指导,用重复测量方差分析比较干预开展前、开展后6、12、18个月各指标变化情况。结果单因素重复测量方差分析结果显示,干预组中所有指标随时间变化均有统计学意义(均有P<0.05),其中饮酒量、吸烟量、油摄入量、盐摄入量、千步当量数、收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)7个方面呈线性趋势;其中饮酒量通过干预减少了5.94 g/d,油、盐摄入量分别减少了4.47 g/d和0.56 g/d,千步当量数增加了10.10/d,SBP从(124.54±5.87)mm Hg降低到(122.40±8.32)mm Hg,DBP从(79.47±4.86)mm Hg降低到(77.14±6.05)mm Hg;而对照组中只有吸烟量、体质指数(body mass index,BMI)和DBP随时间变化有统计学意义且呈线性趋势(均有P<0.05)。多因素重复测量方差分析结果显示,吸烟量、盐摄入量、千步当量数、BMI和DBP的组间差异均有统计学意义(均有P<0.05),且后4个方面存在分组与时间的交互作用。结论社区群组干预对高血压前期人群的生活方式有改善作用,同时也有控制血压的效果。
Objective To investigate the effect of improving lifestyle on people with prehypertension by group intervention.Methods A community-based randomized controlled trial was conducted among 4 streets.188 objects in intervention group took part in the intervention activities and 234 objects in control group were not given the regular guidance.Data collected through questionnaire at baseline,6 months,12 months and 18 months after intervention were compared through repeated ANOVA measurement.Results All the subjects in the intervention group showed statistical significance （all P 〈0.05） and alcohol consumption,smoking,oil intake,salt intake,number of thousand step equivalent,systolic blood pressure （SBP）,diastolic blood pressure （DBP） showed linear trends over time by univariate test of repeated measurement ANOVA.The alcohol consumption decreased 5.94 grams per day after intervention.The oil intake decreased 4.47 grams per day while salt intake decreased 0.56 grams per day.The number of thousand step equivalent increased 10.10 per day,and SBP decreased from （124.54±5.87） mmHg to （122.40 ± 8.32） mmHg.DBP decreased from （79.47 ± 4.86） mmHg to （77.14 ±6.05） mmHg.Only smoking,body mass index （BMI） and DBP had significant change over time in the control group.Smoking,salt intake,number of thousand step equivalent,BMI and DBP were significantly different （all P 〈 0.05） between control and intervention groups,and the effect of interaction between groups and time span were statistically significant （all P 〈 0.05） on indicators as salt intake,number of thousand step equivalent,BMI and DBP,by multivariate test of repeated measurement ANOVA.Conclusions Group intervention can be used to improve lifestyle of prehypertension people in community and control their blood pressure.
