ABSTRACT

Background:

Osteopenia and osteoporosis is posing a long-term and asymptotic influence to aging population health.

Objective:

This sampling survey seek to assess the prevalence of osteopenia and osteoporosis in a Chinese Han population through.

Methods:

A community-based cross-sectional study involving 16,377 subjects used a multistage sampling method. Bone mineral density measurements were made with quantitative ultrasonic densitometry. The prevalence rates of osteoporosis (T-score ≤-2.5) and osteopenia (T= -2.5~-1.0) were calculated and described in age, gender, menopause, and calcium intake groups.

Results:

The prevalence rates of osteopenia and osteoporosis were 40.50% and 7.93% respectively, and the standardized prevalence was 27.32% and 3.51%, respectively. There was an increase in osteopenia and osteoporosis prevalence from 21.50% to 56.20% and 0.90% to 17.20%, respectively, as age increased from 18 years to 75 years old. The prevalence rates of osteopenia and osteoporosis in women (43.94% and 11.72%) were significantly higher than that in men (35.58% and 2.51%) (P<.001), and in postmenopausal women (48.55% and 14.05%) were higher than in premenopausal women (26.55% and 2.62%) (P<.001). In addition, women with a history of calcium intake had a lower osteoporosis prevalence rate than women without any history of calcium intake in all age groups (P<.05). From low quartile to high quartile of T-score, the prevalences of DM (18.63%, 19.33%, 19.75%, and 22.40%) and dyslipidemia (55.20%, 57.21%, 59.26%, and 61.35%) were linearly increased (P<.05), while the prevalence of cancer (2.77%, 2.73%, 2.65%, and 1.99%) was decreased (P<.05).

Conclusions:

Our data imply that as people age, osteopenia and osteoporosis are more common in women than in men, particularly in postmenopausal women than in premenopausal women, and bone mineral density significantly affects the prevalence of chronic diseases.
