00:04In our general understanding
00:06Asians have generally been shorter than Europeans and Americans in terms of average height.
00:10However, in recent decades
00:12Height differences among different countries and ethnic groups in Asia
00:15The gap is also quietly widening.
00:18The Nikkei Asian Review, citing data from a global height research institution, pointed out...
00:23Compared with 30 years ago
00:24Average height of Chinese and Koreans
00:27It has clearly surpassed the Japanese.
00:30In contrast, Japan is the only one of the three countries with an average height of [missing information].
00:34Countries that have clearly stagnated or even shown a downward trend
00:38Although height is largely influenced by parental genes
00:42ring
00:42However, the report quoted expert analysis as saying...
00:45The factors that come into play are also subtly influencing that person.
00:51high
00:51The report points out that as early as 1985
00:54Japanese men have the highest average height at 170.4 cm, surpassing both China and South Korea.
01:00The average height for women is 157.8 centimeters.
01:04Also ahead of China and South Korea
01:06But more than 30 years later in 2019
01:09Average height of 19-year-old boys in China and South Korea
01:12They have already reached 175.7 cm and 175.5 cm respectively.
01:18Japanese men, however, have remained at 172.1 cm.
01:23The gap with China and South Korea has widened to more than 3 centimeters.
01:25The height difference between the girls was as high as 5 centimeters.
01:28Experts emphasize that genetics is not the cause of physiology in men and women in China, Japan, and South Korea.
01:34The main reason for the widening gap
01:36The real culprit is actually related to three major acquired environmental factors.
01:42What exactly is it?
01:43The first major flaw lies in the overly strict weight management of pregnant women.
01:48In the past, Japan had a policy to prevent male childbirth.
01:50It is generally recommended that pregnant women strictly control their weight gain throughout the entire pregnancy.
01:55long
01:55In addition, there has always been a societal phenomenon of giving birth to young children and raising them to adulthood.
02:00This kind of traditional concept
02:01This resulted in a birth weight of less than 2.5 kg in Japan.
02:06This means that the proportion of newborns with low birth weight is as high as 10%.
02:11Studies have found that the average height of these low-birth-weight children as adults is...
02:16They are generally about 2 to 3 centimeters shorter than children with normal birth weight.
02:21rice
02:21This indirectly affects the average height of the entire generation.
02:24That means they might have lost at the starting line during their fetal stage.
02:28Diet and sleep habits after birth also affect height.
02:32Important acquired factors
02:34Influenced by Japan's culture of eating less and the trend of convenience stores serving smaller meals.
02:39The average Japanese person consumes approximately fewer calories per day than the Chinese and South Koreans.
02:44More than 800 calories
02:46That's equivalent to eating about 3 fewer bowls of rice.
02:49Not only that
02:51Japanese people also rank relatively low globally in protein intake.
02:55Ranked only 89th
02:57Such a daily diet may lead to problems during the growth stage.
03:01Insufficient energy and protein intake
03:04at the same time
03:05In Japan, children aged 0 to 3 years old sleep an average of only 11 hours a day.
03:1037 minutes
03:12It is also shorter than China's 12 hours and 30 minutes.
03:15Insufficient nutrition and insufficient sleep can both affect children.
03:21and normal development of adolescents
03:23They missed the crucial growth spurt during their development.
03:27If we look at the global picture, the differences in height between different regions are even more pronounced.
03:32Already
03:32In the global height ranking
03:34European countries almost swept the top 10 spots.
03:37In the Netherlands, the average height for men is 184 cm.
03:41170 cm for women
03:43Dominating the world
03:45And what about East Asia?
03:47Young people in China and South Korea have an average height of approximately 175 centimeters.
03:51Gao stood out
03:52What about Southeast Asian countries like those in the East Titria region?
03:55It is located at the tail end of the global scale.
03:59anyway
03:59What about the height rivalry between China and South Korea?
04:02This also shows us the impact of postnatal nutrition and lifestyle habits on the physical fitness of the next generation.
