Risk factors on dietary pattern were presented as follows: ( 1 )boys: having the food pattern Ⅰ and Ⅱ showed a strong positive association with the place where they live (OR= 1.67, 95％CI: 0.87-3.19; OR= 1.51,95％CI: 0.79-2.88), eating place (OR=1.63,95％CI: 1.O3-2.59; OR= 1.83, 95％CI: 1.04-3.23), level of mother' s education (OR=2.52,95％CI: 1.07-5.95; OR=3.38, 95％CI: 1.50-7.63), family income (OR=2.24, 95％CI: 1.30-3.88;OR=3.06, 95％ CI: 1.77-5.29) and the status of passive smoking (OR= 1.80, 95％CI: 0.70-4.59;OR=1.83, 95％CI: 0.75-4.45). Inverse correlations was found on the level of mother's education (OR=0.56,95％CI: 0.17-1.79). The food pattern Ⅳ showed a strong positive association with place of eating(OR= 1.83,95％CI: 1.04-3.23) but having an inverse correlation with the level of mother's education (OR=0.56, 95％CI: 0.17-1.79).
