Table 2 Intervention effects of the BRA-study on vegetable outcome from baseline to follow-up 2

From: Long-term effects of a cluster randomized controlled kindergarten-based intervention trial on vegetable intake among Norwegian 3–5-year-olds: the BRA-study

 Intervention effect*
Baseline to follow-up 2
Estimate (95% CI)P
Frequency of vegetable intake (times/day)a− 0.1 (− 0.5, 0.2)0.44
Variety in vegetable intake (kinds/month)a− 0.2 (− 1.0, 0.7)0.70
Amount of vegetables consumed (g/day)b− 15.0 (− 38.0, 8.0)0.19
  1. * Fixed effects parameter estimates. Adjusted for kindergarten clustering, time, child gender, child year of birth, maternal education and kindergarten ownership (private or public) and if the child attended school or not
  2. aFrequency and variety of vegetable intake was calculated based on data from Q1. Participants were included in the analyses if they had data on baseline and/or follow-up 1 and/or follow-up 2 and all covariates, n = 462 (n = 236 in the control group and n = 226 in the intervention group)
  3. bAmount of vegetables consumed in one day was calculated based on data from Q2. Participants were included in the analyses if they had data on baseline and/or follow-up 1 and/or follow-up 2 and all covariates, n = 459 (n = 233 in the control group and n = 226 in the intervention group)
