Most reports suggest that BMD is highest in African-Americans, lowest in Asians, and intermediate in Caucasians, yet Asians have lower fracture rates than Caucasians.

Bone density at all skeletal sites was statistically significantly greater in black than in white subjects; on average, adjustment for covariates reduced the percentage density differences by 42% for men and 34% for women.Results: In general, bone mineral density (BMD) as determined by the T-score was highest in mixed martial arts fighters (T-score = 3.1 ± 0.9) and football players (T-score = 2.7 ± 0.7) followed by resistance-trained (RT) males (T-score = 1.9 ± 1.2).
What race is at highest risk for osteoporosis
White and Asian women, aged 50 and over. While men and women of all races can develop osteoporosis, post-menopausal white and Asian women are at highest risk.
Bone biopsy studies show that blacks have greater bone volume. The rate of fractures and cardiovascular diseases are also less frequent. Further studies are required to better understand the cellular and molecular bases of these racial differences in bone mineral metabolism and thus better treat patients.Among black Americans, 4.2 percent have osteoporosis and 29.7 percent have low bone mass. African Americans have a lower risk of breaking a bone in their lifetime, compared to white Americans and other ethnic groups.Although Asians have lower areal bone mineral density (aBMD, g/cm2) (by dual‐energy X‐ray absorptiometry [DXA]),(1–3) rates of hip and wrist fractures are lower among Asian compared with white adults,(1,4,5) and fracture incidence is also lower in Asian children and adolescents compared with their white peers.
Indians have low BMD as compared to the western Caucasians. This could be attributed to differences in skeletal size; however, the high prevalence of vitamin D deficiency is a major factor in the low BMD and poor bone health of Indians.
Do Skinny people have higher bone density
It's well known that there's a direct correlation between bone density and body weight. Thin people generally get lower bone density readings on DEXA scans, and as a group, people whose body mass index classifies them as “underweight” experience more hip fractures than persons of “normal” weight.
Compared with omnivores, vegetarians and vegans had lower BMD at the femoral neck and lumbar spine and vegans also had higher fracture rates. Conclusions: Vegetarian and vegan diets should be planned to avoid negative consequences on bone health.
10 Things to Know About Racial Differences in Bone Health
- Prevalence of osteoporosis and low bone mass (osteopenia) varies among racial and ethnic groups in the United States.
- African Americans have a lower risk of breaking a bone in their lifetime, compared to white Americans and other ethnic groups.

Being Asian is a risk factor for osteoporosis. Having a thin, small boned frame (or low bone mass), low physical activity and low calcium intake also are risk factors. As much as 90% of Asian Americans may be lactose intolerant, therefore obtaining calcium from dairy products proves problematic.The femur is one of the most well-described bones of the human skeleton in fields ranging from clinical anatomy to forensic medicine. Because it is the longest and strongest bone in the human body, and thus, one of the most well-preserved in skeletal remains, it makes the greatest contribution to archaeology.The skull thickness in Black and White adults of both sexes was studied in Rhodesia by two methods. White women have the thickest, and White men the thinnest skulls.A recent study, published in the Journal of the American Geriatrics Society, found Native Americans have denser bones than Caucasians, yet they don't eat a lot of dairy foods. Hip and other bone fractures are often the result of weak bones, caused by osteoporosis, a degenerative bone disease.
DLX3 belongs to the so-called homeobox genes, which regulate the development of tissues including hair follicles, bone, and teeth buds.Past studies suggest that genetic differences may account for more than half the variance in bone mineral density between people. Previous genome-wide association studies identified 24 genetic regions that influence bone mineral density.The risk of osteoporosis and fractures is different in various populations. Individuals of African descent have higher bone density and fewer fractures than Caucasians, whereas Asians have lower fracture rates despite lower bone density.Fragile bones
The research found that although the bones of obese people are denser, they are not as strong as they need to be based on their weight. So, the bone density is not proportionate to their body weight.
Weight-bearing exercises, such as walking, jogging, and climbing stairs, can help you build strong bones and slow bone loss. Avoid substance abuse. Don't smoke. If you are a woman, avoid drinking more than one alcoholic drink each day.Some people might confuse bone size with bone density, which refers to the concentration of minerals in your bones. Like large bones, dense bones may add only a few pounds to your frame.Conclusions: Asians had smaller bones, thicker and denser cortices, and more plate-like trabeculae, but biomechanical estimates of bone strength did not differ between groups.Past studies suggest that genetic differences may account for more than half the variance in bone mineral density between people.
Unbreakable bones – the LRP5 gene
However, a different mutation in the LRP5 gene can also cause an uncommon disorder in which bone density is greatly increased making the bones very strong and resistant to fractures.This may be related to differences in body composition, which is known to differ between ethnic groups. 62, 105 More specifically, black adults were found to have a relatively higher muscle mass (leading to a lower sarcopenia prevalence) compared to whites and Asians.
