OBJECTIVE
To investigate the effects of a long-term, individualized and family-based lifestyle intervention on physical activity, sedentary behavior and diet quality in children.

METHODS
We carried out a 2-year intervention study in a population sample of 506 children aged 6-8 years 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.

RESULTS
Total physical activity (+9 min/d in intervention group vs. -5 min/d in control group, p=0.001 for time*group interaction), unsupervised physical activity (+7 min/d vs. -9 min/d, p<0.001) and organized sports (+8 min/d vs. +3 min/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 (+9 min/d vs. +19 min/d, p=0.003). Consumption of vegetables (+12 g/d vs. -12 g/d, p=0.001), high-fat vegetable-oil based margarine (+10 g/d vs. +3 g/d, p<0.001) and low-fat milk (+69 g/d vs. +11 g/d, p=0.042) and intake of dietary fiber (+1.3 g/d vs. +0.2 g/d, p=0.023), vitamin C (+4.5 mg/d vs. -7.2 mg/d, p=0.042) and vitamin E (+1.4 mg/d vs. +0.5 mg/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 (+2 g/d vs. -1 g/d, p=0.002).

CONCLUSIONS
Individualized and family-based lifestyle intervention increased physical activity, attenuated increase in sedentary behavior and enhanced diet quality in children.
