Mothers' involvement in a school-based fruit and vegetable promotion intervention is associated with increased fruit and vegetable intakes – The Pro Children study

Table 4 Unadjusted values for fruit and vegetable intake and adjusted regression coefficients reflecting difference in intake at follow up between the different groups for the level of involvement

	Intake at baseline (mean +/- SD)	Intake at first follow-up (mean +/- SD)	Regression coefficient¹	95% CI
Total fruit and vegetable intake (gram/day)
Low involved (< 3)	261.8 +/- 172	247.8 +/- 155	ref
Medium involved (3–4)	259.7 +/- 197	284.5 +/- 190	43.8	7.3 – 80.4
High involved (≥ 5)	313.0 +/- 206	339.4 +/- 225	94.7	43.6 – 145.9

¹ Analyses are adjusted for baseline intake level, country and clustered design
Regression coefficient reflects difference in intake at first follow-up compared to the reference group adjusted for baseline values.
