Eating Patterns Linked too Increased Osteoporosis Risk: New Research from japan

AsianScientist (Sep. 27, 2025) – Osteoporosis, a skeletal disorder marked by weakened bones and a higher risk of fracture, is typically associated wiht aging, hormonal changes, and lifestyle factors such as exercise, alcohol consumption and smoking. However, much less is understood about how dietary habits contribute to the risk of osteoporotic fractures.
Now, new research from Japan suggests that everyday eating patterns, such as skipping breakfast or eating late at night, coudl also raise the risk of osteoporosis.
The study, published in the Journal of the Endocrine Society, studied the connection between eating habits and osteoporotic fractures, shedding light on this overlooked risk factor.
“We found skipping breakfast and having late dinners was associated with an increased risk of osteoporosis,” said author Hiroki Nakajima,MD,PhD,of Nara Medical University in Nara,japan.
“Furthermore, these unhealthy eating habits were found to be linked with the accumulation of other lifestyle risk factors such as physical inactivity, smoking and insufficient sleep,” Nakajima added.
Skipping breakfast and eating late dinners have been linked to obesity, type 2 diabetes, and cardiovascular disease, the study states. Skipping breakfast has also been associated with lower bone mineral density (BMD) and a higher risk of fractures,though some genetic studies found no clear link. While a few studies have looked at breakfast skipping and fractures over time,none have examined how late dinners might effect osteoporosis.
Osteoporosis: A Silent Disease
Osteoporosis is a bone disease that develops when bone mineral density and bone mass decreases, or when the structure and strength of bone changes.This can lead to a decrease in bone strength that can increase the risk of broken bones. It is indeed called a “silent” disease as one typically does not have symptoms,and may not even know they have the disease until they break a bone.
It is also the major cause of fractures in postmenopausal women and in older men. Fractures can occur in any bone but happen most often in bones of the hip, vertebrae in the spine, and wrist.
Unhealthy Habits,Higher Risks
The researchers used a large health checkup cohort of 927,130 adults,aged 20 years and older,from the DeSC claims database in Japan. Of the
Further Exploration: Understanding Bone Mineral density
Bone Mineral Density (BMD) is a key measurement used to diagnose osteoporosis. It’s typically measured using a Dual-energy X-ray absorptiometry (DEXA) scan. Here’s a simplified breakdown of BMD categories:
| Category | T-score | Description |
|---|---|---|
| Normal | -1.0 and above | Healthy bone density. |
| osteopenia | Between -1.0 and -2.5
