Families in the intervention communities reported a significantly lower sugar propensity and a higher water propensity compared with families in the control communities, while fat and fruit and vegetables propensities were similar. No significant diet differences between intervention and control children were present at the baseline survey (T0).
Further results on effects of the intervention on consumption of water and sugar we recommend following article:

Recommendation: The enhancement of moderate to vigorous physical activity (MVPA) should have an outstanding place and role in any health-related recommendation. 1 hour/day MVPA may be an unrealistically high target for preschool children.
In boys and girls, no significant differences in physical activity (PA) and sedentary time (ST) were found between intervention and control groups over 2 years. Strong temporal effects were found in the total sample of boys and girls: the percentage of time spent in light PA per day decreased (by 4 percentage points) in both boys and girls between baseline and follow-up, while time spent in ST per day increased (by 4 percentage points) in both sexes over time. Percentage of time spent in moderate to vigorous PA (MVPA) per day remained stable over time in boys and girls.
Despite the socio-ecological approach and implementation of a culturally adapted intervention in each country, no effects of the IDEFICS intervention were found on children’s objectively measured PA and ST. Behavioural interventions for children may need to enhance specificity and intensity at the family level using other behaviour change techniques and more direct strategies to reach parents.
Further results on effects of the intervention on physical activity and sedentary behaviour we recommend following article:

IDEFICS recommends 11 hours or more sleep for pre-school children and 10 hours for school children (6-10 years). Promotion of sufficient sleep should be part of any health-related recommendations.
A small intervention effect was seen on weeknight sleep duration in that the decrease in sleep duration over 2 years was smaller in the intervention (15 min.) as compared with control regions (19 min). There was no overall intervention effect on weekend sleep duration or on the presence of a TV in the bedroom. A small significant time effect between baseline and follow-up was found on bedroom TV presence depending on self-reported intervention exposure. Children without a TV in the bedroom had longer nocturnal sleep duration.
