Bone Health and Osteoporosis Screening: What Working Adults Should Know

Bones feel permanent, but they are living tissue that is constantly broken down and rebuilt. From around our 30s, the balance gradually shifts and we start losing more bone than we build. In some people this loss goes far enough to cause osteoporosis: bones that are thinner, weaker and more likely to break.

The challenge is that osteoporosis usually has no symptoms until a fracture happens. Osteoporosis screening can identify low bone density earlier, when steps can be taken to protect the bones. This article explains who may benefit, how screening works and what everyday habits support bone health. It is general information, not medical advice.

Understanding osteoporosis and osteopenia

• Osteopenia means bone density is lower than average for a young adult, but not low enough to be classed as osteoporosis.
• Osteoporosis means bone density is low enough to significantly increase fracture risk.

Fractures related to osteoporosis commonly affect the hip, spine and wrist. Spinal fractures can sometimes happen with little or no trauma and may show up only as back pain, loss of height or a stooped posture.

Who is at higher risk?

Several factors raise the risk of low bone density:

Risk factor	Why it matters
Being a woman, especially after menopause	Falling oestrogen speeds up bone loss
Older age	Bone density naturally declines
Early menopause or missed periods for long spells	Less time with protective hormones
Family history of osteoporosis or hip fracture	Genetics affect peak bone mass
Low body weight	Associated with lower bone density
Long-term use of certain medicines, such as steroids	Can weaken bone
Smoking and heavy alcohol use	Both harm bone health
Low physical activity	Bones need load to stay strong
Low calcium intake or vitamin D deficiency	Key building blocks for bone
Conditions such as rheumatoid arthritis, thyroid overactivity or malabsorption	Can affect bone metabolism

Vitamin D deficiency is widely reported in India despite plentiful sunshine, partly because of indoor work, covered clothing and limited dietary sources. That makes it a relevant issue for office-based workforces.

How osteoporosis screening works

DEXA scan

The standard test is a dual-energy X-ray absorptiometry (DEXA or DXA) scan, usually of the hip and lower spine. It is quick, painless and uses a very low dose of radiation. You lie on a table while a scanner arm passes over you.

Understanding the T-score

DEXA results are reported as a T-score, which compares your bone density with that of a healthy young adult. The WHO's widely used definitions are:

T-score	Category
−1.0 or higher	Normal bone density
Between −1.0 and −2.5	Low bone density (osteopenia)
−2.5 or lower	Osteoporosis

You may also see a Z-score, which compares you with people of the same age and sex. Doctors often use it for younger adults and premenopausal women.

Fracture risk tools

Bone density is only part of the picture. Doctors may use risk calculators, such as FRAX, that combine bone density with age, sex, weight and other risk factors to estimate the chance of a fracture over the next ten years.

Who should consider osteoporosis screening?

Recommendations vary between guidelines, but doctors commonly consider screening for:

• Women after menopause, particularly with risk factors
• Older women and men
• Adults who have had a fracture from a minor fall
• People on long-term steroid treatment
• Anyone with conditions known to affect bone health

If you fall into one of these groups, ask your doctor whether a DEXA scan is appropriate.

Related blood tests

Blood tests do not measure bone density, but a doctor may order them to look for factors affecting bone:

• Vitamin D
• Calcium and phosphorus
• Thyroid function
• Kidney function
• Alkaline phosphatase

Reference ranges vary between labs, and there is ongoing discussion among experts about ideal vitamin D levels, so results should be interpreted by a doctor.

Protecting your bones at any age

1. Move with impact and resistance. Walking, climbing stairs, dancing and strength training all help bones. Long hours of sitting do not.
2. Get enough calcium. Dairy, ragi, sesame, leafy greens and fortified foods are common sources in Indian diets.
3. Support vitamin D. Safe sun exposure and diet help; supplements should be taken only as advised by a doctor.
4. Eat enough protein. Bones need protein as well as minerals.
5. Avoid smoking and limit alcohol.
6. Prevent falls. Good lighting, clear walkways and attention to balance and eyesight matter, especially as we age.

What employers can do

• Include bone health in women's health programs, with awareness sessions around menopause
• Offer DEXA scans as part of executive or over-40 checkups where a doctor considers it appropriate
• Encourage movement through walking challenges, stretch breaks and stair-friendly offices
• Address workplace fall risks such as poor lighting, wet floors and cluttered walkways

Frequently Asked Questions

Is a vitamin D blood test the same as a bone density test?

No. A vitamin D test measures one nutrient that supports bone health. A bone density (DEXA) scan measures the bones themselves. Normal vitamin D does not rule out low bone density, and vice versa.

Can men get osteoporosis?

Yes. It is more common in women after menopause, but men can develop it too, particularly with older age, long-term steroid use, smoking, heavy alcohol use or low testosterone.

Is a DEXA scan safe?

A DEXA scan uses a very low dose of X-rays and is quick and painless. Tell the technician if you are or might be pregnant, or if you recently had a scan using contrast.
