What is the most important genetic factor influencing whether someone will develop osteoporosis?
A
diet
B
gender
C
exercise
D
age
Explanation: 

Detailed explanation-1: -Family history. If your parents or grandparents have had osteoporosis or any signs of osteoporosis, such as a fractured hip after a minor fall, you may be more likely to get it, too. Bone structure and body weight. Petite and thin women have a greater chance of developing osteoporosis.

Detailed explanation-2: -The prevalence of osteoporosis and the risk of fracture are higher in women than in men. This is partially due to differences in BMD, bone size, and bone strength between men and women. Even though women fracture more often, men tend to have worse outcomes after fractures.

Detailed explanation-3: -Genetics in Bone Health Genetics play a substantial role in determining an individual’s skeletal strength, bone microarchitectural properties and risk of osteoporosis. BMD is known to be a highly heritable trait and twin studies have shown genetic factors to determine up to 80% of its variance (13, 14).

Detailed explanation-4: -Women are more at risk of developing osteoporosis than men because the hormone changes that happen at the menopause directly affect bone density. The female hormone oestrogen is essential for healthy bones. After the menopause, oestrogen levels fall.
