Ying Yang Bao (YYB) is a soybean powder-based complementary food supplement containing vitamin A, D, B1, B2, B6, folic acid, calcium, iron and zinc. YYB can be used as a home fortification product in complementary feeding through adding it to porridge, noodles and other homemade complementary foods. YYB has been evidenced improving nutrition status such as a decrease in anemia, low weight and stunting, while demonstrating an increasing cognitive performance in 6- to 24-mo-old infants in a series of observations in poor rural regions in China. In 2012, the Ministry of Health initialed the project “Improving Children’s Nutrition in Poor Regions,” targeted to cover all 6- to 24-mo-old infants with YYB in poor rural counties integrated with distribution of nutrition knowledge to the guardians. By the end of 2014, Chinese government had continuously invested 400 million RMB for purchase of YYB product and distribution to the families in 300 poor counties and 12 million infants had been covered. Monitoring and evaluation data conducted by China CDC in 1,800 infants and their guardians from 6 counties in Shanxi, Yunnan and Hubei provinces showed on average: the anemia rate significantly dropped from 32.9% to 26.0%, the stunting rate from 10.1% to 8.4%, the diarrhea rate from 14.2% to 9.4%, and the cost for clinic payment from 98.8 RMB to 74.4 RMB, while the nutrition knowledge of guardians increased from 29.6% to 38.5% after 1 year’s intervention of the project from March, 2013 to March, 2014. The consumption duration is 7.2 mo, coverage of YYB is 85.9% and application of YYB is 52.0%. The project planned to invest 500 million RMB for 2015 to enlarge the coverage to 341 counties, and about 137 million infants will benefit.
