- Abstract
To investigate the calcium nutrition condition and to explore its association with osteoporosis prevalence of in middle-aged and elder population in Shanghai Minhang District. Methods A questionnaire investigation was conducted and physical examination was performed in 1460 over 50 years old regular residents in Shanghai Minhang District. BMD of the lumbar spine,total hip,femur neck,and Wards triangle was measured using dual energy X-ray absorptiometry. Fasting serum and urine calcium were determined with chemiluminescence method . Osteoporosis,osteopenia,and normal bone mass were diagnosed according to World Health Organization (WHO) criteria. Urinary calcium level below 1. 7 mmol /L was diagnosed as calcium deficiency. Urinary calcium level above 5. 3 mmol /L was diagnosed as high calcium loss. The rest was normal urinary calcium. Results Among 1460 subjects,337 were osteoporosis (23. 08%) ,and 420 were normal bone mass (28. 77%) . Osteoporosis prevalence was 4. 12% in males and 37. 88% infemales. Urinary calcium deficiency was found in 365 persons (25. 0%) . High calcium loss was found in 176 persons (12. 1%) . Calcium deficiency was 30. 32% in males and 22. 78% in females. The highest urinary calcium level (3. 67 mmol /L) was found in subjects below 60 years old in osteopenia group. The 3-year changes of urinary calcium level were significant in female osteoporosis groups. Conclusion Calcium deficiency is higher in males than in females, but osteoporosis prevalence is much higher in females than in males. Calcium deficiency is common in aged population. Calcium deficiency plus high calcium loss are the main factors leading to senile osteoporosis. In the process of preventing osteoporosis in aged population,it is very important to avoid high calcium loss besides calcium supplement.
