What information does the nurse teach a women's group about osteoporosis?

Choice A reason: While men can develop osteoporosis and may be underdiagnosed, women—especially postmenopausal—have significantly higher rates due to estrogen deficiency. This statement misrepresents the epidemiology of the disease. Choice B reason: This is accurate. Primary osteoporosis is most common in postmenopausal women due to the decline in estrogen, which plays a key role in bone remodeling and calcium retention. Estrogen deficiency accelerates bone resorption, increasing fracture risk. Choice C reason: This is incorrect. Women are at higher risk due to hormonal changes, lower peak bone mass, and longer life expectancy. Men are less likely to develop osteoporosis unless they have secondary causes. Choice D reason: This is false. Osteoporosis can be prevented or slowed through lifestyle modifications such as weight-bearing exercise, calcium and vitamin D supplementation, and pharmacologic interventions like bisphosphonates.
