维生素D缺乏性佝偻病(简称佝偻病)是婴幼儿的一种常见病。一般认为,佝偻病的患病率、沉重度与纬度有关,在我国北方较南方多发而且病情较重。广西地处祖国南疆,属亚热带气候,位于北纬21°32′～26°27′,年日照量达1600～1900小时。但佝偻病并不少见。南方佝偻病的患病因素与防治对策,很值得研究。 1979年在区卫生局领导下,佝偻病协作组开展了全区性婴幼儿佝偻病的调查工作,分别於春、秋两季对12190名婴幼儿进行了调查,现将调查结果报告如下: Vitamin D deficiency rickets (referred to as rickets) is a common disease in infants and young children.
