How Long Do Short People Live? Exploring Height and Longevity

Are you curious about the connection between height and lifespan? Do short people live longer? At HOW.EDU.VN, we delve into the research to uncover the potential link between stature and longevity, exploring factors like genetics, lifestyle, and disease risk that may contribute to a longer lifespan for shorter individuals. Discover how variations in the FOX03 gene, body size composition, and reduced risk of certain health conditions might play a role in increased lifespan.

1. Do Short People Really Live Longer?

Longevity refers to a “long life” or the duration of a life. While it’s a common assumption that being tall equates to a healthier and longer life, numerous studies suggest otherwise. Genetics and a healthy lifestyle also significantly impact health and longevity.

Here’s what the research reveals regarding height and lifespan:

1.1 The Role of the FOX03 Gene

Variations in the FOX03 gene are linked to longevity in both humans and animals. This gene is also associated with body size and various biological processes crucial for maintaining health throughout life, including substrate metabolism (chemical reactions), protein turnover, and cell survival and death.

Variations of this gene can also provide protection against certain diseases, including type 2 diabetes, cardiovascular disease, cancer, and neurological disorders.

A 2014 observational study published in PLOS One examined the FOX03 genotype and its correlation with height and lifespan in Japanese American men. The researchers discovered that men who were 5 feet, 2 inches or shorter were more likely to possess the protective FOX03 gene variant and experience longer lifespans. Conversely, those taller than 5 feet, 4 inches were found to have shorter lifespans and less protection.

1.2 Height Above Average and Increased Risk of Early Death

A 2017 study investigated the correlation between height and longevity among former professional basketball players. The researchers discovered that a taller body might lead to a reduced lifespan.

This study included 3,901 living and deceased players who played basketball between 1946 and 2010. The players had an average height of 6 feet, 5 inches. The top 5% in height experienced earlier deaths compared to the players at the bottom 5% in height.

It’s important to note that genetics, socioeconomic status, healthcare access, weight, education, smoking habits, nutrition, and exercise can also influence lifespan.

1.3 Taller Men Living Shorter Lives

A long-term observational study published in 2012 revealed that Italian men under 5 feet, 3 inches lived at least two years longer than their taller counterparts. The study analyzed death rates among men born between 1866 and 1915 in the same Italian village.

Researchers discovered that while the average lifespan for that specific group was 70 years, taller men lived approximately two years less than shorter men. Interestingly, when the study participants were born, the average height in their village was around 5 feet, 2 inches, considered short by today’s standards.

1.4 Body Size and Sex

Research has explored body size differences between men and women and their effects on lifespan. Women generally live longer than men, and researchers often attribute this to the impact of disease on males versus females.

The average height for individuals assigned female at birth in the United States is 5 feet, 4 inches, while it is 5 feet, 9 inches for individuals assigned male at birth.

Globally, women live one to 11 years longer than men. It is possible that having smaller bodies or being shorter gives people assigned female at birth an advantage over their peers assigned male at birth when it comes to longevity.

1.5 Associated Health Risks

Certain health risks are associated with human height:

Venous thromboembolism (VTE): VTE is a life-threatening condition where blood clots form in the veins and block blood flow. A 2017 study examined the link between height and VTE among 2 million Swedish siblings.

The study found that men shorter than 5 feet, 3 inches had a 65% lower risk of VTE compared to men taller than 6 feet, 2 inches. Additionally, pregnant individuals who were 5 feet, 1 inch or shorter had a 69% lower risk of VTE compared to pregnant individuals 6 feet and taller.

Researchers theorize that people with longer legs and tall people experience greater leg stasis (blood collection in the lower legs) due to increased hydrostatic pressure (pressure exerted by liquids within blood vessels).
All causes and cancer: A 2016 study examined the connection between height, cancer risk, and death from all causes by analyzing the death certificates of 14,440 men and 16,390 women aged 25 and older.

The researchers determined that each additional inch in height meant a 2.2% higher risk of death from all causes for men and a 2.5% higher risk for women. They also found that each additional inch meant a 7.1% increased risk of death from cancer for men and a 5.7% increased risk of death from cancer for women.
Atrial fibrillation (A-fib): A-fib is a dangerous heart rhythm disorder. Research from the European Society of Cardiology found that taller and larger-framed women were up to 3 times more likely to develop A-fib than shorter, smaller-framed women.

According to the 16-year study, the larger the body as a young adult, the higher the likelihood of developing A-fib. This is potentially due to the increased size of the atria in the heart in larger people, which could disrupt electrical pathways and put extra pressure on the lungs due to body size.

2. Why Might Height Affect Life Expectancy?

Research on mortality has shown that smaller, shorter bodies tend to have lower death rates and fewer diet-related chronic or serious illnesses. This finding has been consistent across both human and animal studies. Examples of diet-related conditions include high blood pressure, diabetes, obesity, osteoporosis, and gallstones.

While factors like nutrition and access to healthcare play a role in longevity, the specific reasons why shorter people might live longer are not fully understood.

Here are some potential explanations:

Caloric needs: Taller individuals may require a higher caloric intake to maintain proper bodily functions. They have longer and heavier bones and larger internal organs.
Fewer cells: Taller individuals have millions more cells than shorter individuals. This increased cell count can lead to greater exposure to free radicals (unstable molecules produced by cell metabolism that can damage DNA) and both external and internal toxins.
Less cell repair: As the body ages, it must work harder to repair tissues. The more cells a person has, the more repairing is required, which may affect lifespan.

3. Factors Affecting Life Expectancy

Life expectancy has generally increased over the past several decades but has slowed and even decreased after 2014. A major contributor to this increase in mortality is rising death rates from specific causes among young and middle-aged adults, including drug overdoses, suicides, organ system diseases, and, since 2020, COVID-19.

Beyond illness, suicide, and overdose, multiple factors influence mortality and life expectancy:

Sex: On average, females live longer than males. According to the Centers for Disease Control and Prevention (CDC), the life expectancy in 2022 was 80.2 years for U.S. females and 74.8 years for U.S. males.
Genetics: Variations in genes contribute to the risk of many health conditions that can affect overall mortality.
Prenatal or childhood conditions: Poor conditions in utero (in the womb), at birth, or in early childhood could reduce your lifespan.
Higher socioeconomic status: A higher socioeconomic status could lead to improved longevity due to better access to healthcare for both physical and mental health, and participation in a healthier lifestyle, such as exercise, not smoking, maintaining a healthy weight, and eating a healthier diet.
Ethnicity: Some ethnicities tend to live longer. According to the CDC, life expectancy among Hispanic people is higher than among non-Hispanic Blacks or Whites.

3.1 Life Expectancy in the United States

In 2022, life expectancy in the United States was 77.5 years, representing an average of:

Males: 74.8 years
Females: 80.2 years

4. How to Live Longer and Healthier: Expert Advice

While size and genetics play a role in health and mortality risks, other controllable factors, such as diet, exercise, smoking status, and alcohol use, significantly impact lifespan.

Adopting the following healthy habits can help you live longer and healthier:
