【摘要】：目的评价青海省重点监测地区营养改善计划实施3年后学生营养状况及贫血检出率变化,以促进营养改善工作的有效开展。方法采用自身前后对照的现场干预试验方法,比较2012年和2015年青海省3个县(区)监测学生的身高、体重、营养不良和贫血的患病状况。结果与2012年相比,2015年监测点9~11岁男生的平均身高分别增加了1.9,1.8和4.8 cm,差异均有统计学意义(P值均0.05);9~12岁女生的平均体重分别增加了1.1~2.6 kg,差异均有统计学意义(P值均0.05)。经过3年的营养改善计划干预,9~11岁学生消瘦和营养不良的检出率明显降低,差异均有统计学意义(χ~2值分别为7.2,7.1,P值均0.05);6~15岁学生的贫血检出率从2012年的10.5%下降到2015年的4.3%,差异有统计学意义(χ~2=56.1,P0.01)。结论青海省营养改善项目对重点监测地区中小学生的身高、体重及贫血有明显的改善效果,各级政府应持续并加大对"计划"项目的投入力度,从而有效改善全省农村中小学生的营养健康水平。
[Abstract]:Objective to evaluate the changes of nutritional status and anemia detection rate of students in Qinghai province after the implementation of nutritional improvement plan for 3 years in order to promote the effective development of nutritional improvement. Methods A self-controlled field intervention trial was conducted to compare the prevalence of height, weight, malnutrition and anemia among students in three counties (districts) of Qinghai Province in 2012 and 2015. Results compared with 2012, the average height of boys aged 9 ~ 11 years in 2015 increased by 1.910 ~ 1.8 cm and 4.8 cm, respectively, and the difference was statistically significant (P = 0.05). The average body weight of girls aged 12 years was increased by 1.1 ~ 2. 6 kg, respectively, and the difference was statistically significant (P = 0.05). After 3 years of intervention, the prevalence of wasting and malnutrition among students aged 11 years was significantly decreased. The difference was statistically significant (蠂 ~ 2 = 7.2 ~ 7.1 P = 0.05). The prevalence rate of anemia decreased from 10.5% in 2012 to 4.3% in 2015. The difference was statistically significant (蠂 ~ (2 / 2) 56.1g / (P) 0.01). Conclusion the nutrition improvement project of Qinghai Province has obvious effect on improving the height, weight and anemia of primary and middle school students in key monitoring areas. Governments at all levels should continue and increase their investment in the "Plan" project. So as to effectively improve the nutritional health of rural primary and secondary school students in the province.
