为了评价和改进噪声作业工人营养健康状况,对135名接触噪声作业的工人进行了营养调查。调查发现:男工摄入碳水化合物、VB_2、VC、钙、铜不足或偏低(分别为RDA的70.14％、61.80％、55.21％、76.50％),女工摄入钙、锌、铜不足或偏低(分别为RDA的46.77％、79.57％、79.00％;热能和其他营养素摄入量均达到RDA的80％以上,基本能满足机体需要。男、女工早餐热能摄入偏低(占总热能的14～21％),晚餐较高(占总热能43～51％)。血清总蛋白、血清白蛋白、血红蛋白水平低于正常者分别为17％、11％,7％(男)、38％(女)。尿中VB_1、VB_2、VC低于正常者分别为:4％、28％、71％。部分工人出现舌乳头肥大、舌肿大、齿龈萎缩等营养缺乏体征。因此,应向工人群众宣传合理营养知识,并适当调整膳食结构,使达到平衡膳食。
In order to evaluate and improve the nutrition and health status of noise-exposed workers, 135 nutrition workers were interviewed for noise. The survey found that male workers’ intake of carbohydrates, VB_2, VC, calcium and copper was low or low (70.14%, 61.80%, 55.21% and 76.50% of RDA, respectively) Low (respectively RDA 46.77%, 79.57%, 79.00%; thermal and other nutrients intake reached more than 80% of the RDA, basically to meet the needs of the body.Male and female workers breakfast calorie intake is low (total heat 14 to 21%), dinner was higher (43 ~ 51% of the total heat), serum total protein, serum albumin and hemoglobin were 17%, 11%, 7% Female) .The urinary VB_1, VB_2, VC were lower than normal were: 4%, 28%, 71% .There were some workers with tongue nipple hypertrophy, swollen tongue, gingival recession and other nutritional deficiencies.Therefore, workers should be Propagate reasonable nutrition knowledge and adjust dietary structure appropriately to achieve a balanced diet.
