将膳食因素与锌摄入量作多元线性回归分析，得出多元回归方程：锌摄入(mg)=-0.426+0.053×蛋白质摄入(g)+0.003×磷摄入(mg)+0.234×锌贮留(mg)+0.078×粗纤维摄入(g)(n=27，P＜0.001，R2=0.927)。初步认为5～6岁儿童每日摄入5～6mg锌就能保证发育，这个锌摄入水平可能是目前膳食条件下锌的需要量。从多元回归方程可以看出，锌的需要量受膳食因素影响。各国各地区居民膳食因素不同，所以锌需要量也不完全一致。

Based on present Chinese dietary composition、 nutritional condition and zinc metabolic balance, we suggest that 5-6mug di- etary zinc intake is enough for children 5 - 6 years old. 5 - 6mg zinc intake could be the zinc requirement for them at present. We gave a multiple regression formula to estimate zinc intake:Zinc in- take = - 0. 426 + 0. 053×protein intake(g) + 0. 003×phosphorus intake(mg) + 0.234×zinc retention(mg) + 0.078×fiber intake (g). Dietary factors influencing zinc requirements have been iden- tified. Zinc requirements will change with the different levels of di- etary factors.
