This paper aims to emphasize the significance of creating subnational nutrition action plans in regions with high variation in nutrition challenges and evaluates their projected return on investment in Kenya. Despite steady progress, undernutrition in Kenya remains high, costing the country an estimated US$ 4.2 billion or 7% of its GDP annually. Under Kenya's decentralized government system, numerous counties developed sectoral County Nutrition Action Plans (CNAPs) in 2018 to identify and prioritize essential nutrition actions to target undernutrition at the subnational level. In this paper, the authors present findings from county investment cases (CICs) in five counties - Nandi, Busia, Makueni, Vihiga, and Elgeyo Marakwet-including the costs, health impacts, and benefit to cost ratios of implementing high-impact nutrition interventions. Data was collected on the target coverage and cost of interventions prioritized in each county's CNAPs for the 2018 to 2022 period. A monetized DALY approach, using the value of a statistical life methodology was used for cost-benefit analysis and the Optima Nutrition tool was used for cost-effectiveness analysis. The estimated cumulative impact of the five CNAPs was projected as 1,800 child and 115 maternal deaths averted; preventing and treating 19,000 cases of stunting and 4,700 cases of wasting in children under five and averting 67,000 cases of anaemia in pregnant women and adolescent girls. The county-level benefit-cost ratios range from $5:1 to $14:1 (at a default 3% discount rate). This analysis demonstrates that localized subnational plans can be advantageous for policymaking and prioritization to better address subnational disparities in undernutrition and offer a high return on investment.
本文旨在强调在营养挑战差异较大的地区制定次国家级营养行动计划的重要性,并评估其在肯尼亚的预计投资回报率。尽管取得了稳步进展,但肯尼亚的营养不良状况仍然严重,估计该国每年为此付出42亿美元,占其国内生产总值的7%。在肯尼亚的分权政府体制下,许多县在2018年制定了部门性的县营养行动计划(CNAP),以确定并优先开展基本营养行动,在次国家级层面解决营养不良问题。在本文中,作者介绍了五个县——南迪、布西亚、马库埃尼、维希加和埃尔盖约-马拉奎特——的县投资案例(CIC)的研究结果,包括实施高影响力营养干预措施的成本、对健康的影响以及成本效益比。收集了2018年至2022年期间各县CNAP中优先干预措施的目标覆盖范围和成本数据。采用货币化伤残调整生命年方法,利用统计生命价值法进行成本效益分析,并使用Optima营养工具进行成本效益分析。预计这五项CNAP的累计影响为避免1800例儿童死亡和115例孕产妇死亡;预防和治疗19000例五岁以下儿童发育迟缓病例和4700例消瘦病例,并避免67000例孕妇和少女贫血病例。县级成本效益比在5:1至14:1之间(默认贴现率为3%)。该分析表明,本地化的次国家级计划有利于政策制定和优先排序,以更好地解决次国家级层面营养不良方面的差异,并提供高投资回报率。
