Stunting cases in DI Yogyakarta itself are at 16.6%, even though this figure is below the national rate (30.8%) and the problem of stunting in Sleman Regency is low at 6.88%, but we still must be vigilant because if left unchecked the impact is very serious on the formation of the quality of human resources.
