A cross-sectional nutrition survey was conducted in five different rural areas of Kenya. Plasma protein and plasma albumin levels, plasma amino acid ratio, urinary nitrogen: creatinine ratio, urinary inorganic sulfate sulfur: creatinine ratio, and the urinary hydroxy-proline index were determined in children aged 1-15 years. The biochemical results were compared with those from a dietary and anthropometric survey. It was concluded that the amino acid ratio, the urea nitrogen: creatinine ratio and the inorganic sulfate sulfur: creatinine ratio were the most useful biochemical tests to establish differences between communities associated with varying adequacy of protein-calorie intake.
在肯尼亚五个不同的农村地区进行了一项横断面营养调查。测定了1至15岁儿童的血浆蛋白和血浆白蛋白水平、血浆氨基酸比值、尿氮：肌酐比值、尿无机硫酸盐硫：肌酐比值以及尿羟脯氨酸指数。将这些生化结果与饮食和人体测量调查的结果进行了比较。得出的结论是，氨基酸比值、尿素氮：肌酐比值和无机硫酸盐硫：肌酐比值是确定与蛋白质-热量摄入充足程度不同相关的社区之间差异最有用的生化检测指标。
