In China, a full fat soy powder mixed with multiple micronutrient powders (Ying Yang Bao (YYB)) was developed, and the efficacy of YYB was shown in controlling anaemia and improving child growth and development. However, prior to 2008, there was no sustainable way to provide YYB to vulnerable populations, except through free distribution by the government. This study was to test the concept of public-private partnership (PPP) to deliver YYB and to evaluate the effectiveness of marketing YYB through PPP. Programme activities included development of a complementary food supplement (CFS) national standard, product concept test, product development and marketing, behavior change communication, monitoring and evaluation. Baseline and end-line surveys were used to evaluate product awareness, purchasing and the impacts of the project on anaemia and feeding practices. A Chinese CFS standard was approved. Caregivers and their 6- to-24-month-old children participated in the baseline (n=226) and the end-line survey (n=221). A concept test at the baseline survey showed that 78% of caregivers were willing to buy YYB at 0.1 USD. After developing the product and implementing the intervention for 8 months, 59.6% of surveyed caregivers purchased YYB. While not significant, the prevalence of anaemia was marginally lower at the end line (28.8%) than at the baseline (36.2%). For those purchasing YYB, the risk of anaemia was significantly reduced by 87% of odds (P<0.009). The end-line survey found that feeding practices had improved significantly following the intervention. An enabling policy and regulatory environment in which CFSs are defined and parameters for appropriate marketing are identified as a prerequisite for marketing YYB or other nutritious CFS. Public and private advocacy and marketing could successfully increase awareness of YYB and access and use through market channels. The YYB project may be effective for reducing anaemia and improving feeding practices.
在中国，开发了一种全脂大豆粉与多种微量营养素粉（阴阳宝（YYB））混合的产品，并证明了 YYB 在控制贫血和改善儿童生长发育方面的功效。然而，在 2008 年之前，除了政府免费分发之外，没有可持续的方法向弱势群体提供 YYB。本研究旨在测试公私合作伙伴关系（PPP）提供 YYB 的概念，并评估通过 PPP 营销 YYB 的效果。项目活动包括制定补充食品（CFS）国家标准、产品概念测试、产品开发和营销、行为改变沟通、监测和评估。使用基线和终线调查来评估产品意识、购买情况以及项目对贫血和喂养实践的影响。批准了中国 CFS 标准。看护人和他们 6-24 个月大的孩子参加了基线（n=226）和终线调查（n=221）。基线调查的概念测试表明，78%的看护人愿意以 0.1 美元的价格购买 YYB。在开发产品并实施干预 8 个月后，59.6%的调查看护人购买了 YYB。虽然不显著，但终线时贫血的患病率（28.8%）略低于基线时（36.2%）。对于那些购买 YYB 的人，贫血的风险降低了 87%（P<0.009）。终线调查发现，干预后喂养实践有了显著改善。一个有利的政策和监管环境，其中定义了 CFS 并确定了适当营销的参数，被认为是营销 YYB 或其他有营养的 CFS 的前提。公共和私营部门的宣传和营销可以成功提高对 YYB 的认识，并通过市场渠道增加获取和使用。YYB 项目可能对减少贫血和改善喂养实践有效。
