Metabolic syndrome is prevalent among Vietnamese adults, especially those aged 50-65 years. This study evaluated the effectiveness of a 6 month community-based lifestyle intervention to increase physical activity levels and improve dietary behaviours for adults with metabolic syndrome in Vietnam.
Ten communes, involving participants aged 50-65 years with metabolic syndrome, were recruited from Hanam province in northern Vietnam. The communes were randomly allocated to either the intervention (five communes, n = 214) or the control group (five communes, n = 203). Intervention group participants received a health promotion package, consisting of an information booklet, education sessions, a walking group, and a resistance band. Control group participants received one session of standard advice during the 6 month period. Data were collected at baseline and after the intervention to evaluate programme effectiveness. The International Physical Activity Questionnaire - Short Form and a modified STEPS questionnaire were used to assess physical activity and dietary behaviours, respectively, in both groups. Pedometers were worn by the intervention participants only for 7 consecutive days at baseline and post-intervention testing. To accommodate the repeated measures and the clustering of individuals within communes, multilevel mixed regression models with random effects were fitted to determine the impacts of intervention on changes in outcome variables over time and between groups.
With a retention rate of 80.8%, the final sample comprised 175 intervention and 162 control participants. After controlling for demographic and other confounding factors, the intervention participants showed significant increases in moderate intensity activity (P = 0.018), walking (P < 0.001) and total physical activity (P = 0.001), as well as a decrease in mean sitting time (P < 0.001), relative to their control counterparts. Significant improvements in dietary behaviours were also observed, particularly reductions in intake of animal internal organs (P = 0.001) and in using cooking oil for daily meal preparation (P = 0.001).
The prescribed community-based physical activity and nutrition intervention programme successfully improved physical activity and dietary behaviours for adults with metabolic syndrome in Vietnam.

代谢综合征在越南成年人中普遍存在，尤其是年龄在50 - 65岁的人群。本研究评估了一项为期6个月的基于社区的生活方式干预措施对提高越南患有代谢综合征的成年人身体活动水平和改善饮食行为的有效性。
从越南北部的河南省招募了10个社区中年龄在50 - 65岁患有代谢综合征的参与者。这些社区被随机分配到干预组（5个社区，n = 214）或对照组（5个社区，n = 203）。干预组参与者接受了一套健康促进方案，包括一本信息手册、教育课程、一个步行小组和一条弹力带。对照组参与者在6个月期间接受了一次标准建议。在基线和干预后收集数据以评估项目效果。国际体力活动问卷简表和一份改良的STEPS问卷分别用于评估两组的身体活动和饮食行为。干预组参与者仅在基线和干预后测试时连续7天佩戴计步器。为了适应重复测量和社区内个体的聚类情况，采用了具有随机效应的多级混合回归模型来确定干预对随时间和组间结果变量变化的影响。
保留率为80.8%，最终样本包括175名干预组参与者和162名对照组参与者。在控制了人口统计学和其他混杂因素后，与对照组相比，干预组参与者在中等强度活动（P = 0.018）、步行（P < 0.001）和总身体活动（P = 0.001）方面有显著增加，平均久坐时间减少（P < 0.001）。饮食行为也有显著改善，特别是动物内脏摄入量减少（P = 0.001）以及日常做饭食用油用量减少（P = 0.001）。
所规定的基于社区的身体活动和营养干预方案成功改善了越南患有代谢综合征的成年人的身体活动和饮食行为。
