[Association between fruit availability at home and fruit-related eating behavior among sixth-grade schoolchildren in Sakado City, Japan].
OBJECTIVE
The recommended daily intake of fruits in Japan is 200 g, but average actual intake is much lower. We examined associations between self-reported fruit availability at home and fruit-related eating behavior among sixth-grade schoolchildren in Sakado City, Saitama Prefecture, Japan.


METHODS
As part of a larger study of school children in Sakado City, 659 sixth-grade from all 13 primary schools in the city completed a survey in their classroom in October 2007 (valid respondent rate 92%). Dietary intake over the previous 1-month period was assessed with a brief, self-administered diet history questionnaires for 10-year-olds. A second questionnaire also assessed health, dietary knowledge, attitudes and behaviors, and perceived food availability at home. Children reported fruit availability at home using the four options of always, often, sometimes, or never. Associations between fruit availability at home and fruit-related eating behaviors were statistically tested, including perception of the importance of and self-efficacy in eating fruits for health as well as the frequency of eating fruit by children and their family, with all analyses conducted separately by gender.


RESULTS
Mean fruit intake was the highest among those children who reported that fruits were always available at home (boys 54 g/1,000 kcal, girls 65 g/1,000 kcal), followed by those reporting availability as often (31 g/1,000 kcal, 37 g/1,000 kcal), sometimes (16 g/1,000 kcal, 13 g/1,000 kcal), or never (9 g/1,000 kcal, 12 g/1,000 kcal). Availability was positively associated with intake (P for trend < 0.001). Additionally, it was positively associated with childrens' perception of the importance of eating fruit for better health (boys only, P < 0.001), self-efficacy in eating more fruit (P < 0.001), and the family frequency of eating fruit (P < 0.001).


CONCLUSIONS
These findings suggest that fruit availability at home is a significant factor in fruit-related eating behavior, consistent with results of similar studies in western countries.
