This study aimed at assessing the effectiveness regarding implementation and impact of a take-home nutrition supplementation programme, the Protein Energy Malnutrition (PEM) Scheme, that targets malnourished pre-school children and pregnant and lactating women in the Northern Cape Province of South Africa.
In assessing implementation of the PEM Scheme, a cross-sectional descriptive study was undertaken over a 6-month period in the six regions of the Northern Cape Province. Interviews were conducted with programme managers and health personnel at clinics who were responsible for implementing the PEM Scheme. In assessing the impact of the PEM Scheme on growth, a retrospective review was done of the clinic records (including anthropometric data) of children enrolled in the PEM Scheme over a 1-year period.
About 76% of the budget allocated to the PEM Scheme had been utilised over the 1-year period. The budget for the following financial year was based solely on food supplements purchased in the previous year. Coverage of malnourished pre-school children and eligible pregnant and lactating women for enrolment was estimated to be 50% and 60%, respectively. Eighty-five per cent of health facilities in the province participated in the PEM Scheme. Some of the main problems identified included: lack of training, inappropriate targeting of certain groups, incorrect application especially of discharge criteria for pregnant and lactating women, inadequate assessment for nutrition-related disease, inadequate nutrition counselling and no standardised monitoring. Of the 319 children enrolled over a year, the mean age was 16.2 (standard deviation 16.2) months, 41% had been low-birth-weight and 18% had been diagnosed with tuberculosis. Ten per cent of the children with a weight-for-age Z-score of <-2 moved into the normal Z-score range after being on the PEM Scheme for a mean duration of 8 months. There was an overall improvement in the weight-for-age Z-scores of 25% of the sample, with a significant difference between the mean weight-for-age Z-scores at enrolment and follow-up This was mainly related to significant improvement in the mean weight-for-age Z-scores of children <2 years.
Numerous problems with the PEM Scheme have been identified which could have limited its impact. Recommendations are proposed for improving the effectiveness and impact of the PEM Scheme in the province.
本研究旨在评估一项家庭营养补充计划——蛋白质能量营养不良(PEM)计划的实施效果及其影响。该计划针对南非北开普省营养不良的学龄前儿童以及孕妇和哺乳期妇女。
在评估PEM计划的实施情况时,于北开普省的六个地区进行了为期6个月的横断面描述性研究。对负责实施PEM计划的项目经理和诊所的卫生人员进行了访谈。在评估PEM计划对生长发育的影响时,对参与PEM计划的儿童在1年期间的诊所记录(包括人体测量数据)进行了回顾性分析。
在这1年期间,分配给PEM计划的预算约76%已被使用。下一个财政年度的预算仅基于上一年购买的食品补充剂。据估计,营养不良学龄前儿童以及符合条件的孕妇和哺乳期妇女的登记覆盖率分别为50%和60%。该省85%的卫生设施参与了PEM计划。发现的一些主要问题包括:缺乏培训、某些群体的目标定位不当、特别是孕妇和哺乳期妇女出院标准的错误应用、营养相关疾病评估不足、营养咨询不足以及缺乏标准化监测。在1年中登记的319名儿童中,平均年龄为16.2(标准差16.2)个月,41%为低出生体重,18%被诊断患有结核病。年龄别体重Z评分<-2的儿童中,10%在参与PEM计划平均8个月后进入正常Z评分范围。样本中25%的年龄别体重Z评分总体有所改善,入组时和随访时的平均年龄别体重Z评分之间存在显著差异。这主要与2岁以下儿童的平均年龄别体重Z评分的显著改善有关。
已确定PEM计划存在诸多问题,这些问题可能限制了其影响。针对提高该省PEM计划的有效性和影响提出了建议。
