Vietnam's surprising surge in average height over the past decade has put the country in the spotlight, but it's not just a numbers game. While it's true that Vietnamese men have grown an impressive 3.7 cm and women 2.6 cm, ranking fourth in Southeast Asia, there's more to this story than meets the eye. In this article, I'll delve into the factors driving this growth, the challenges that remain, and the broader implications for Vietnam's workforce and society.
A Surprising Rise
What makes Vietnam's height gain particularly fascinating is the pace at which it has occurred. Truong Hong Son, director of the Vietnam Institute of Applied Medicine, notes that the country's average male height has reached 168.1 cm and female height 156.2 cm, a significant jump from previous decades. This surge has lifted Vietnam past Indonesia and the Philippines, placing it just behind Singapore, Malaysia, and Thailand in Southeast Asia.
But in the modern global context, Vietnam's growth is still slow. The country is placed in the bottom 30% of nations measured by the NCD Risk Factor Collaboration, and Vietnamese young men remain roughly 3 cm shorter than the global male average of 171 cm. So, while Vietnam has made impressive strides, there's still a long way to go.
The Drivers of Growth
So, what's driving Vietnam's height gain? Son points to three key factors: diets short on micronutrients, unscientific lifestyles, and low rates of physical activity among school-age children. Of the four factors shaping stature, he says, genetics accounts for about 23% and nutrition for 32%, with the rest driven by exercise and sleep.
In my opinion, the fact that Vietnam's schools have not built consistent fitness habits or evenly distributed nutrition education across the system is particularly concerning. While genetics and nutrition are important, the role of exercise and sleep cannot be understated. A lack of physical activity and poor sleep habits can significantly impact growth, especially in children and adolescents.
The Challenges That Remain
Despite Vietnam's impressive progress, there are still significant challenges to overcome. Son notes that the country's growth rate is still slow, and Vietnamese young men remain roughly 3 cm shorter than the global male average. This highlights the need for continued efforts to address the factors that are holding back growth, such as diets short on micronutrients and low rates of physical activity.
One thing that immediately stands out is the need for a three-pronged intervention covering nutrition, exercise, and applied research. This approach, framed by officials, is crucial to addressing the complex factors that impact growth. However, it's not just about intervention; it's also about creating a culture that values health and wellness.
Broader Implications
Vietnam's height gain has broader implications for the country's workforce and society. A resolution issued by the Politburo in 2025 calls for adding at least 1.5 cm to the average height of Vietnamese aged 1 to 18 by 2030. If current trends hold, Vietnamese men could reach roughly 172 cm and women 159 cm by then.
From my perspective, this raises a deeper question: how can Vietnam ensure that its workforce remains competitive in a global economy? While height may be one factor, it's not the only one. Vietnam needs to focus on building a healthy and skilled workforce that can compete on the global stage.
Conclusion
In conclusion, Vietnam's surprising surge in average height is a testament to the power of addressing the right factors. However, it's not just a numbers game. Vietnam needs to continue addressing the challenges that remain, such as diets short on micronutrients and low rates of physical activity, to ensure that its workforce remains competitive in a global economy. As Son notes, the country's growth rate is still slow, and there's still a long way to go. But with continued efforts, Vietnam can build a healthier and more competitive workforce for the future.
