Within the last 25 years, the average Vietnamese man became 5 cm taller, while the average Vietnamese woman became 4 cm. According to RIA ‘Novosti’, this was shown by the results of scientific monitoring carried out by Vietnamese specialists. Since 1996, the scientists have studied a large group of people within the ages of 6-20. The height of the average Vietnamese man today is 1,67 m, while his weight is 53,3 kg; the average Vietnamese woman is 1,54 m tall and weighs 47 kg. The Vietnamese suppose the these figures are comparatively small. For example, average heights and weights in China, Japan, Singapore are larger. Football-players from Vietnam are even smaller than sportsmen from neighbouring Laos. According to the scientists, the reason is that diet of the Vietnamese people is not balanced enough.
