１９９０～１９９３年对山东省农村贫困地区３０００余名学龄前儿童开展了营养监测与改善工作。基线调查表明，儿童膳食植物性食物占９０％以上，动物性食物摄入量少且品种单调。每日蛋白质、热量及其它大部分营养素的摄入量未达到供给量标准．营养不良发生率为１４．９％～１６．８％，血红蛋白低下率平均为６２．２％。针对存在问题，实施了营养干预措施。１９９３年调查表明，血红蛋白低下率已降至１３．３％，群众营养知识水平已有较大提高。建议进一步加强营养知识宜教，国家应该从立法上对营养工作给予保障。
From 1990 to 1993, more than 3,000 preschool children in rural poverty-stricken areas in Shandong Province were monitored and improved their nutrition.

Daily intake of protein, calories and most other nutrients did not meet the supply standards. The incidence of malnutrition was 14.9% ~ 16.8%, the average hemoglobin low rate was 62.2%. In response to the problem, nutrition interventions were implemented. In 1993, the survey showed that the low hemoglobin rate has dropped to 13.3%, and the mass nutrition knowledge level has been greatly improved. Proposal to further strengthen nutrition knowledge should be taught, the state should from the legislative protection of nutrition work.
