To investigate the effects of a long-term, individualized and family-based lifestyle intervention on physical activity, sedentary behavior and diet quality in children.
We carried out a 2-year intervention study in a population sample of 506 children aged 6-8years in Finland in 2007-2012. We allocated the participants at baseline in the intervention and control group. We assessed physical activity and sedentary behavior by questionnaires and diet by food records.
Total physical activity (+9min/d in intervention group vs. -5min/d in control group, p=0.001 for time*group interaction), unsupervised physical activity (+7min/d vs. -9min/d, p<0.001) and organized sports (+8min/d vs. +3min/d, p=0.001) increased in the intervention group but not in the control group. Using computer and playing video games increased less in the intervention group than in the control group (+9min/d vs. +19min/d, p=0.003). Consumption of vegetables (+12g/d vs. -12g/d, p=0.001), high-fat vegetable-oil based margarine (+10g/d vs. +3g/d, p<0.001) and low-fat milk (+69g/d vs. +11g/d, p=0.042) and intake of dietary fiber (+1.3g/d vs. +0.2g/d, p=0.023), vitamin C (+4.5mg/d vs. -7.2mg/d, p=0.042) and vitamin E (+1.4mg/d vs. +0.5mg/d, p=0.002) increased in the intervention group but not in the control group. Consumption of butter-based spreads increased in the control group but not in the intervention group (+2g/d vs. -1g/d, p=0.002).
Individualized and family-based lifestyle intervention increased physical activity, attenuated increase in sedentary behavior and enhanced diet quality in children.

探讨长期、个性化且基于家庭的生活方式干预对儿童身体活动、久坐行为和饮食质量的影响。
2007年至2012年，我们在芬兰对506名6至8岁儿童的人群样本进行了一项为期2年的干预研究。在基线时将参与者分配到干预组和对照组。我们通过问卷评估身体活动和久坐行为，通过食物记录评估饮食情况。
干预组的总身体活动增加（干预组增加9分钟/天，对照组减少5分钟/天，时间*组交互作用p = 0.001），无监督身体活动增加（干预组增加7分钟/天，对照组减少9分钟/天，p < 0.001），有组织的体育活动增加（干预组增加8分钟/天，对照组增加3分钟/天，p = 0.001），而对照组没有变化。干预组使用电脑和玩电子游戏的增加量低于对照组（干预组增加9分钟/天，对照组增加19分钟/天，p = 0.003）。干预组蔬菜摄入量增加（干预组增加12克/天，对照组减少12克/天，p = 0.001），以植物油为基础的高脂肪人造黄油摄入量增加（干预组增加10克/天，对照组增加3克/天，p < 0.001），低脂牛奶摄入量增加（干预组增加69克/天，对照组增加11克/天，p = 0.042），膳食纤维摄入量增加（干预组增加1.3克/天，对照组增加0.2克/天，p = 0.023），维生素C摄入量增加（干预组增加4.5毫克/天，对照组减少7.2毫克/天，p = 0.042），维生素E摄入量增加（干预组增加1.4毫克/天，对照组增加0.5毫克/天，p = 0.002），而对照组没有变化。对照组以黄油为基础的涂抹酱摄入量增加，干预组没有变化（干预组减少1克/天，对照组增加2克/天，p = 0.002）。
个性化且基于家庭的生活方式干预增加了儿童的身体活动，减缓了久坐行为的增加，并提高了饮食质量。
