OBJECTIVE
First, to explore item pools developed to measure the physical home environment of pre-school children and assess the psychometric properties of these item pools; second, to explore associations between this environment and vegetable consumption among Norwegian 3-5-year-olds.

DESIGN
Data were collected in three steps: (i) a parental web-based questionnaire assessing the child's vegetable intake and factors potentially influencing the child's vegetable consumption; (ii) direct observation of the children's fruit, berry and vegetable intakes at two meals in one day in the kindergarten; and (iii) a parental web-based 24 h recall.

SETTING
The target group for this study was pre-school children born in 2010 and 2011, attending public or private kindergartens in the counties of Vestfold and Buskerud, Norway.

SUBJECTS
A total of 633 children participated.

RESULTS
Principal component analysis on the thirteen-item pool assessing availability/accessibility resulted in two factors labelled 'availability at home' and 'accessibility at home', while the eight-item pool assessing barriers resulted in two factors labelled 'serving barriers' and 'purchase barriers'. The psychometric properties of these factors were satisfactory. Linear regression of the associations between vegetable intake and the factors showed generally positive associations with 'availability at home' and 'accessibility at home' and negative associations with 'serving barriers'.

CONCLUSIONS
This age group has so far been understudied and there is a need for comparable studies. Our findings highlight the importance of targeting the physical home environment of pre-school children in future interventions as there are important modifiable factors that both promote and hinder vegetable consumption in this environment.
