About two-thirds of 90 clinics treating phenylketonuria (PKU) now recommend indefinite continuation of a low phenylalanine diet as compared to 1978 when fewer than one-fourth had this policy. The percentage of children maintained on diet has increased markedly for six to eight year-olds. Greater conservatism in clinic diet recommendations likely reflects reports of adverse consequences following diet discontinuation and negative individual clinic experiences.
与1978年相比,如今治疗苯丙酮尿症(PKU)的90家诊所中约有三分之二建议无限期持续采用低苯丙氨酸饮食,而在1978年,只有不到四分之一的诊所有此政策。6至8岁儿童坚持饮食治疗的比例显著增加。诊所饮食建议方面更大的保守性可能反映了有关停止饮食后出现不良后果的报告以及个别诊所的负面经验。
