Statistics from


Vietnam is experiencing a significant change in its economic conditions, such a change has been accompanied by significant changes in the pattern of morbidity and mortality. The country’s Gross Domestic Product (GDP) is increasing at a fast pace: from US$31 176 000 000 in 2000 to US$241 272 000 000 in 2018; and the country has experienced remarkable gains in combatting poverty and hunger. Gross National Income per capita has increased from US$110 in 2000 to US$2400 in 2018.1 At the moment the country is ranked in the low middle income countries by the world population review. Parallel with the economic growth, the country has experienced a fast and wide process of urbanisation. Over the past 20 years, more and more Vietnamese have moved from the rural areas to large urban areas with a projected urbanisation rate of 40% by early 2020. The rapid urbanisation has been accompanied by environment deterioration, increased air pollution, deterioration of lifestyle habits (including physical inactivity and diet changes) and a big strain in healthcare services.2–4 This remarkable financial success has been accompanied by a significant reduction in communicable diseases that have been substituted in the ranking of major causes of mortality and morbidity by non-communicable diseases (NCDs), as shown in figure 1. The burden of communicable diseases in Vietnam has significantly diminished from representing 38% and 33% of the morbidity and mortality burden in 1996 to a projected 18% and 6%, respectively, in 2026. The projected mortality burden of 6% for communicable diseases is significantly lower than the projected average burden for other countries in South East Asia (SEA). The successful efforts in combatting communicable diseases has been the main reason for the observed increase in life expectancy. The average life expectancy in Vietnam in 2017 was 79.2 years for women and 70 years for men, with an increase of (6.5 years in women and 5 years in men between 1990 and 2017). Vietnam is one of SEA countries with the highest number of elderly individuals (60+)5 (11 million people, representing 11.95% of the population in 2017). Two million out of these 11 million people are over 80 years old. It is estimated that in 2038 the elderly will represent approximately 20% of the population. This rapid and significant shift in the age distribution of the population will create a significant increase in the demand of healthcare services for elders.

The shift in some of the leading causes of death is represented in table 1.6 7 Cardiovascular disease (CVD) represents the most important cause of death followed by cancer. In terms of both death and disability, CVD remains the first cause followed by road injuries, diabetes and lung cancer. For CVD, the leading cause of death and disability is stroke followed by ischaemic heart disease (IHD), these two causes of death represent by themselves the two leading single cause of death in Vietnam. Road injuries represent the third leading cause of death and disability.

Leading causes of death in 1990 and 2017

This shift has resulted in a parallel shift in healthcare expenditures with the expenditures for NCD representing the biggest single cause of health expenditures in 2013 (table 2).

Health expenditure by disease types

Cancers represent the second leading cause of death, with liver cancer being the leading cause of death in men and breast cancer in women. In terms of prevalence, table 3 showed that liver and lung cancer represent the most prevalent cancers in men while breast and colorectal cancer are the most prevalent cancers in women.

Disease factors


Vietnam Heart Association adopted the definition of American College of Cardiology/American Heart Association of prehypertension as systolic pressure between 120 to 139 mm Hg or diastolic pressure between 80 to 89 mm Hg and hypertension as systolic pressure more than 140 mm Hg or diastolic pressure more than 90 mm Hg.8

High blood pressure both prehypertension (41.8%) and hypertension (20.7%) prevalence is high in Vietnam, with men showing higher prevalence than women and inhabitants of rural areas showing the highest prevalence rate.

Of significant concern is the fact that only 26% of the Vietnamese are aware of their hypertension status. This challenge is particularly relevant in rural areas where only 24% of hypertensive are aware of their high blood pressure (in contrast to 38.4% in urban areas). The data on control of hypertension underlines the need for educational campaigns both in the population and in the medical community. Successful treatment amounts to 32.4% of the treated hypertensives and only 2.8% of all hypertensives have their blood pressure under control. As for the awareness figures men and residents of rural areas are among the groups with lower level of control.


Diabetes is on the rise as well in Vietnam with the number of Vietnamese with diabetes increasing steadily over time. Unfortunately the projections indicate that this rise will continue in the foreseeable future with prevalence of diabetes almost doubling between 2010 (2.9%) and 2030 (4.4%) (figure 2).9 10

National surveys reported that low-density lipoprotein levels experienced a significant increase of 36.6% in 2017 comparing to levels of 2007.

Lifestyle factors

Lifestyle factors like diet and nutrition, physical inactivity, smoking and alcohol uses also contribute significantly to the death and disability burden in Vietnam.11

Diet and nutrition

The traditional Vietnamese diet is considered to be a healthy one. Like many Asian diets, the Vietnamese diet is low in fat, with small amounts of meat and fish, and rich in vegetables, with regional variation and a higher consumption of vegetables in the northern regions.11 12 The healthy profile of the traditional Vietnamese diet from the cardiovascular point of view is confirmed by the data from the 2015 national survey on the risk factors for non-communicable disease that indicate that Vietnamese adults have low average levels of serum cholesterol (181.8 mg/dL in women and 166.3 mg/dL in men). Unfortunately, the national nutrition surveys indicate that the diet of Vietnamese is rapidly changing and while great improvement have been made in the past 20 to 30 years in improving micronutrient and macronutrient deficiencies, the data show a significant increase in the percentage of food intake from animal sources from 12% in 1985 to 21% in 2010. The mean intake per capita per day of meat and poultry steadily increased from 11 g in 1985 to 84 g in 2010. Oil and fat consumption increased 500% between 1985 and 2010. On the contrary consumption of vegetables has gradually decreased from 214 g/capita/day in 1985 to 190 g/capita/day in 2010.13 The recent wave of fast food products brought into the country by international operators is imposing a significant and rapid shift in the dietary habits of Vietnamese and a further worsening of the traditional habits of men and women, especially in the young age groups.

Physical inactivity

The traditional life of Vietnamese is characterised by high-calorie-expenditure, due mostly to rural work and manual labour. These pattern is rapidly changing due to the rapid urbanisation and the type of jobs and work activities that characterise work in an urban setting. In order to replace the calories traditionally expended in work activities, urban Vietnamese need to focus on increasing their leisure physical activity. Unfortunately, data from a survey from the Ministry of Health shows that 70% of adult Vietnamese do not engage in vigorous physical activity and that office workers walk, on average, only 600 steps a day, instead of the recommended 10 000. A recent international study places Vietnam among the countries in the world with the lowest average number of steps walked on a daily basis. More worrisome are the data showing that the new generations of Vietnamese have adopted a lifestyle characterised by high level of sedentary behaviour with only 18% of fifth graders in Ho Chi Minh City meeting the physical activity guidelines.

Overweight and obesity

Of particular concern are the temporal trends in overweight and obesity with prevalence increasing 550% nationally between 1993 and 2015, as shown in figure 3. The highest prevalence of overweight and obesity is observed in urban areas and in women older than 35 years of age. While the absolute values of the prevalence of obesity are still significantly lower than many industrialised countries, the rapid increasing trends are of concern.

Unfortunately, while the Vietnamese traditional diet can be considered healthy from the point of view of the sources and the amount of fats and vegetables, it is characterised (like many other traditional Asian diets) by a high intake of salt. Vietnamese studies indicate that the average daily consumption of salt is approximately 18 to 22 g/day, an amount that is significantly more than the WHO recommended daily intake of 5 g/day.14 Major sources of salt intake in Vietnam are instant noodles and canned foods. Unfortunately, the popular and beloved morning food: pho, may represent by itself a significant source of salt in the diet of Vietnamese with an average content of 2 to 3 g salt in a bowl.


Vietnam has experienced a significant change in the consumption of alcohol that has paralleled the observed improvement in GDP. Vietnam represents the third largest beer consumer in Asia and the per capita consumption of liquor has increased 90% between 2010 and 2017. Vietnamese men drink when celebrating occasion including Lunar New Year, holidays, wedding, housewarmings as well as in regretful circumstance like funeral or death anniversaries. In addition, alcohol is used to facilitate business transactions. Heavy drinkers comprises of 25.1% of Vietnamese males above the age of 15. The effects of this heavy drinking are seen with the high level of liver cirrhosis and road traffic injuries. Prevalence of alcohol use disorders and dependence are reported to be around 9.8% and 5.9%, respectively. The alcohol-attributable year of life lost score for Vietnam is 4, higher compared with other countries in the region.15 16 In addition, alcohol consumption is associated with other dangerous behaviours like smoking and unprotected sex.15 Drinking and driving is responsible for 75% of deaths due to road traffic injuries. The government has enacted a number of national interventions in order to reduce the harms related to alcohol use and abuse (ie, excise tax on alcohol, legal minimum age of 18 for purchasing and consumption of alcoholic beverages). The latest intervention has been implemented on 1st January 2020 lowering the level of alcohol content for driving while intoxicated to less than 0.05 g/100 mL. As previously indicated, it appears that this intervention may have reduced the number of road accidents but not the fatality rate.

Active and passive smoking

Smoking is an important risk factors for numerous causes of death and disability. As for the other lifestyle risk factors the figures are worrisome especially in men, with the most recent data showing a prevalence of smoking of approximately 45% in men and 1.1% in women. These figures represent a 5.3% reduction from the 2010 figures. While the trends are favourable, the observed reduction was lower than expected and efforts need to intensify in order to accelerate this positive trends.17

The high prevalence of smoking is relevant not only for the smokers themselves but for all the people who are unintentionally exposed to passive smoking. Data from the World Bank indicates that home and workplace are the leading source of secondhand smoking exposure in Vietnam with 67.6% of non-smokers exposed in their homes and 49% exposed in the workplace (figure 4).18

Environmental factors

Air pollution

Finally, in addition to individually determined exposure based on lifestyle habits we need to consider environmental exposures that affects the life and the quality of life of individuals and communities in Vietnam. Among these, air pollution represents a significant threat both for the significant impact it has on human health and the significant exposures present in Vietnam especially in urban areas.

Air pollution has been linked, among many other diseases, to CVD, lung disease and cancer and acute lower respiratory infection in children.

SEA is the part of the world were air pollution and its health sequelae are significantly higher than other parts of the world and, unfortunately temporal trends indicate that this negative primacy has not been adequately addressed.

Data from Vietnam indicate that transportation and industrial production represent the major causes of production of carbon monoxide, nitric oxide, sulphur oxide and volatile organic compounds, an important target for prevention strategies (table 4).19

Road injuries

Despite the decreasing trend of death related to road injuries in six consecutive years since 2012, their mortality toll is still relatively high. In 2018, 24 970 people died from traffic injuries in Vietnam. It is one of the leading causes of death and in the top three of premature death after stroke and ischaemic heart diseases. The burden for road injuries are among the top five causes of health expenditure. Drinking and driving and the non-use of helmet are considered the two major causes of traffic-related injuries. Other causes include use of mobile phones while driving, and the quality of helmets for motorcycle riders. The issuance of the obligatory helmet law in 2007 by the government resulted in a significant decrease in traffic injuries.20 Since 1st January 2020 the government has implemented a new law of alcohol harm prevention that appears to have reduced the number of road injuries by 18% in the period of celebration of the Lunar New Year of 2020 comparing to that of 2019 (Vietnam Ministry of Health report). Unfortunately, during the same period, mortality from road injuries has increased by 12%. The data indicates that this new traffic safety law has had some impact, but there is need to further evaluate this discrepancy between the reduction in road injuries and the increase in road fatalities.

Reflections, comments and conclusions

Cardiovascular disease is the leading killer in Vietnam with its two major components: stroke and IHD, representing by themselves the leading causes of death. At a variance with what is seen in industrialised countries stroke claims more victims than IHD every year. This pattern is not unique to Vietnam and is shared by other countries in SEA and the rest of Asia (eg, China). The reason for this primacy of stroke over IHD are not known but it has been observed and discussed for a number of years. Many hypotheses have been put forward including the relatively low intake of protein and the high intake of salt. The diet heart hypothesis suggests that the impact of hypertension, diabetes, smoking and other risk factors in a population characterised by a low atherogenic diet is more significant in the arteries of the brain than in those of the heart. As the diet of these countries changes toward a more westernised diet the CVD pattern changes and IHD becomes more prominent than stroke.21 22 The success in the prevention and treatment of communicable diseases has been the most critical force behind the observed increase in life expectancy of Vietnamese. The challenge the nation faces now, in order to ensure that this gain in life expectancy, morbidity and disability is sustained and improved, is to avoid the worsening of the lifestyle habits that are major risk factors for cardiovascular disease and to successfully treat the conditions (eg, high blood pressure, diabetes, high blood cholesterol) that are major causes of IHD, stroke, other CVD manifestations and other debilitating chronic conditions and causes of death. The figures regarding the prevalence, awareness and control of hypertension are alarming especially the very low level of hypertensives who are aware, under treatment and successfully controlled. These figures indicate the need to implement education strategies for both the community at large and the healthcare professionals.

Diabetes is increasing as well with its prevalence estimated to almost double by 2030. Low level of physical activity, overweight and obesity play an important role in determining the projected increase.

Unfortunately, as described, the major lifestyle habits of Vietnamese are quickly changing toward an unhealthier pattern that will affect the long-term improvements observed to date in Vietnam.

The westernisation of the traditional Vietnamese diet with its high density of calories, and high content of fats, animal fats, simple sugars, low intake of fruits and vegetables will eventually be reflected in an increase in cardiovascular disease burden, especially if this is not accompanied by comprehensive strategies to prevent and successfully treat high blood pressure and diabetes and successful campaign to reduce smoking and its powerful deleterious impact not only on smokers but to those who live and work around them. Overweight and obesity prevalence are low in Vietnam and the current figure place Vietnam among the countries in the world with the lowest prevalence of obesity, however the trend observed are worrisome and if unchecked the current trends will seriously impact the health of the Vietnamese people. Smoking and heavy alcohol consumption represent a significant public health challenge that is limited, for the most part to men in both rural and the urban areas. Education and prevention strategies have been implemented but their success to date has been minimal.

Finally, air pollution represents a significant threat to human health and well-being in whole SEA and Vietnam in particular. In the urban areas, traffic represents a significant source of air pollution. The best approach to address this use is by increasing the public transportation options, especially those with low emission (train, electric buses and so on). The reduction of high emitting cars, scooters and motorcycle can significantly improve the air quality of urban areas. Another significant source of air pollution in Vietnam is the industry and the thermal electricity generation through coal-fired plants especially with regard to nitric oxide and sulphur oxide.

Recognising the effects of harmful use of alcohol, tobacco smoking, pollution, nutrition and life style change on people health, Vietnam government has enacted policies and regulations to reduce these risk factors. Recently the government strengthened the laws that can prevent alcohol abuse and its health consequences, these include: severe penalties for drinking and driving, sale of alcoholic beverages not allowed to individuals under 18 years of age, stores and restaurants nearby hospitals and schools are not allowed to sell alcohol, prohibition of advertisement for alcohol products with an alcohol content of 15 degrees or more. These legislative efforts have been coupled with educational campaigns like those aimed at educating people to control their alcohol consumption and to learn skills that would allow individuals to refuse if they are pressured to drink by the social circumstances. The law on tobacco harm prevention aimed at reducing smoking and its harmful effects has been in place since 2012 and include the banning of tobacco advertising, the setting of 18 as the age for the purchase of tobacco products, ban of cigarette vending machine. In term of traffic safety, in 2007 the law mandating the use of helmet for motorbikes/scooters drivers was enacted and since then the country has experienced a 4.6% reduction in fatalities due to road accidents.

Vietnam is a dynamic country that is experiencing a fast and significant change in its economy with dramatic modifications in the economic and social conditions of many Vietnamese. This transformation has been associated with significant changes in the pattern of morbidity and mortality with a significant increase of life expectancy (21 years over the past 50 years) and a predominance chronic diseases as the main cause of death and disability. It is important, in order to sustain and improve the gains in life expectancy, to address the environmental and lifestyle risk factors that have been identified as playing a major role in the aetiology and pathogenesis of chronic diseases. The current trends in these risk factors is unfavourable, and it is important that a multipronged approach be embraced by individuals and communities; an approach that includes legislative action and education campaigns, aimed at the public and healthcare professionals, that will help in understanding the health impacts of behaviours and the critical importance of preventing and treating them when identified.
