巴马在广西壮族自治区西北部,是地势高的大山区,其自然条件与人们的生活型式,长期以来都具有相对稳定的特点。对90岁以上的老年人作一历史与现状的调查,可能找出有关营养与健康的关系的因素。山区的自然与社会状况尽管比城市单纯,但环境与社会对机体的影响仍然是多方面的且往往又是综合的,因而本调查仅涉及营养和与营养有关的一部分医学因素。

Physical check and some biochemical tests have been done.Being chiefly vegetarians corn is the most common food that provides the needed protein s. But beans like soybeans,lima beans and lentils are their favourites and a special oil seed, Canabi s Sativa L,provides them with plenty of saturated fatty acid.The protein in the diet is about 10% of the calorie and is equivaelent to about 1 gram per Kg body weight in about 1410 Kcal daily. The pulse rate of the old folks normal. 72.41 per minute.Blood lipid also quite normal, plasma cholesterol 142.3±33.87 per 100ml.The life pattern of the old folks here may drop some hints as to the mystery of longevity.
