海南省461例0 ~ 3岁儿童维生素A营养状况及其影响因素分析

Analysis of factors associated with vitamin A nutritional status among 461 children aged 0 – 3 years in Hainan Province

  • 摘要:
    目的 了解海南省0 ~ 3岁儿童血清维生素A营养状况,并探讨其影响因素,为应对维生素A缺乏问题提供科学依据。
    方法 采用分层随机抽样的方法,抽取海南省5个市县在乡镇卫生院进行健康体检的461例0 ~ 3岁儿童为研究对象,收集其人口学特征、喂养情况等信息,采用高效液相色谱法对其进行血清维生素A含量测定,分析比较不同特征儿童血清维生素A水平和维生素A缺乏情况的差异。
    结果 461例儿童中男276例、女185例,血清维生素A水平为(369.12 ± 134.81)ng/mL,边缘缺乏率为24.73%,缺乏率为9.33%。不同性别的儿童维生素A营养状况比较差异无统计学意义(P > 0.05)。各年龄段儿童血清维生素A水平差异有统计学意义(P < 0.05),0 ~ < 6月龄组边缘缺乏率(45.98%)和缺乏率(22.99%)最高,随月龄增加边缘缺乏率和缺乏率均降低(r = − 0.414,P < 0.05)。城市儿童血清维生素A水平高于农村儿童,边缘缺乏率和缺乏率低于农村儿童,差异均有统计学意义(均P < 0.05)。每天摄入水果、维生素A补充剂的儿童血清维生素A水平均高于摄入频率 ≤ 6次/周的儿童,边缘缺乏率和缺乏率均低于摄入频率 ≤ 6次/周的儿童,差异均有统计学意义(均P < 0.05)。分层回归分析显示,控制人口学特征变量后,摄入水果情况能解释维生素A营养状况2.10%的变异。
    结论 海南省0 ~ 3岁儿童维生素A缺乏状况属于轻度公共卫生问题,应提高3岁以下儿童维生素A缺乏情况的监测力度,及时通过添加维生素A补充剂、合理膳食等手段加以干预。

     

    Abstract:
    Objective To investigate nutritional status of serum vitamin A among children aged 0 – 3 years in Hainan Province and factors associated with it, so as to provide scientific evidence to address vitamin A deficiency problem.
    Methods Stratified random sampling method was used to recruit 461 children aged 0 – 3 years who underwent health checkups at township health centers in 5 cities and counties in Hainan Province as study subjects. High-performance liquid chromatography was used to assess serum vitamin A levels, while information of the children’s demographic and feeding characteristics were collected. The serum vitamin A levels and vitamin A deficiency of children with different characteristics were analyzed and compared.
    Results There were 276 males and 185 females. The average serum vitamin A levels was (369.12 ± 134.81) ng/mL, with a marginal deficiency rate of 24.73% and a deficiency rate of 9.33%. There was no difference in the serum vitamin A levels between different gender (P > 0.05), while the differences between children of different age groups were statistically significant (P < 0.05). The highest marginal deficiency rate (45.98%) and the deficiency rate (22.99%) were in the 0 − < 6 months age group, and the marginal deficiency rate and the deficiency rate decreased with months (r = − 0.414, P < 0.05). Urban children had higher serum vitamin A levels and lower marginal deficiency and deficiency rates than those of rural children (P < 0.05). Children who had fruit and vitamin A supplements intake daily had higher serum vitamin A levels and lower marginal deficiency and deficiency rates than those whose intake frequency ≤ 6 times/week (P < 0.05). Stratified regression analysis showed that fruit intake interpreted 2.10% of the variation in vitamin A nutritional status after controlling for demographic variables.
    Conclusion Vitamin A deficiency among children aged 0 – 3 years in Hainan Province is a mild public health issue. Monitoring should be enhanced, and timely vitamin A supplements intake and balanced diet should be the main intervention strategies.
