【摘要】 目的了解0～6岁儿童血清维生素A(Vit A)水平及相关影响因素。方法选取2017年4月～2019年4月于河北省沧州中西医结合医院儿科门诊就诊0～6岁儿童445名,进行问卷调查。检测血清Vit A水平,观察并分析0～6岁儿童在不同性别、季节和年龄间Vit A水平以及Vit A缺乏情况。结果不同性别Vit A水平及缺乏情况比较,差异均无统计学意义(P> 0.05)。不同季节间血清Vit A含量比较,差异有统计学意义(P <0.05),进一步两两比较,夏季、秋季Vit A显著高于冬季,差异有统计学意义(P <0.05)。不同年龄血清Vit A比较,差异有统计学意义(P <0.05),其中≤6个月儿童Vit A水平最低(P <0.05)。其他年龄儿童Vit A水平比较,差异无统计学意义(P> 0.05)。不同季节、年龄血清Vit A缺乏情况比较,差异有统计学意义(P <0.05)。回归分析显示,季节和年龄是Vit A水平的影响因素。结论针对冬季、低年龄段儿童及时进行Vit A检测及适量的Vit A补充是必要的。更多还原

【Abstract】 Objective To investigate the serum vitamin A(Vit A) levels and related influencing factors in children aged0 to 6 years. Methods From April 2017 to April 2019, a total of 445 children aged 0 to 6 years who were treated in the pediatric clinic of Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine of Hebei Province were selected for questionnaire survey. Serum Vit A levels were measured, and the levels of Vit A and the deficiency of Vit A among children aged 0 to 6 years of different gender, season and age were observed and analyzed.Results There were no significant differences in Vit A levels and deficiencies between different genders(P > 0.05).There was a statistically significant difference in serum Vit A levels between different seasons(P < 0.05). Further comparison, the Vit A levels in summer and autumn were significantly higher than those in winter, and the differences were statistically significant(P < 0.05). Comparison of serum Vit A at different ages, the differences were statistically significant(P < 0.05). Among them, the levels of Vit A were the lowest in children less than 6 months(P < 0.05). There were no significant differences in the levels of Vit A among children of other ages(P > 0.05). While the difference in serum Vit A deficiency was statistically significant(P < 0.05). Regression analysis showed that season and age were influencing factors of Vit A levels. Conclusion It is necessary to perform Vit A test and appropriate Vit A supplement in time for children in winter and low age.更多还原
