为了了解贵阳市城区儿童少年肥胖状况及肥胖的相关因素，采用体重测量法对贵阳城区数所小学共４ １９５ 名学生进行肥胖流行病调查。同时使用１∶１ 配对研究方法，随机抽取１３５ 名单纯性肥胖儿童与对照组进行２４ ｈ 膳食营养及生活行为习惯、机能状态等相关因素的比较研究。结果显示：肥胖率为６－６５ ％ ，其中男学生８－４８ ％ ，女学生４－７５ ％ ，肥胖的高峰年龄是１０ ～１２ 岁，主要表现为轻度肥胖（６６－６７ ％ ） 。肥胖儿童的各营养素摄入量均高于对照组儿童，并存在明显家族遗传倾向，同时表现为不好运动，机能状态较差等（ Ｐ＜ ０－０５） 。根据本调查的结果，认为贵阳市儿童少年的肥胖检出率比较高，造成肥胖的原因有营养摄入多而运动少，并有一定的家族遗传性。
