Prevalence of low bone mass and endocrine disorders in hip fracture patients in Southern Germany
Abstract
UNLABELLED: Low bone mass and conditions leading to falls are considered to determine the risk of hip fracture. Bone mass is influenced by underlying diseases and risk factors such as malnutrition and life style habits. In order to evaluate the clinical significance of osteopenia and risk factors in the pathogenesis of hip fracture, we have studied 146 consecutive patients (27 males, 119 females, aged 53-95 years) undergoing rehabilitation shortly after hip fracture (4 cases of hip fracture resulting from traffic accidents had been excluded). We measured bone mineral density (BMD) at the hip (DXA, Hologic QDR 2,000+), evaluated vitamin D status (serum 25-OH-Vitamin D) and nutritional calcium intake (clinical dietician), and searched for endocrine disorders (physical examination and serum hormones). Femoral neck BMD was 0.543 +/- 0.084 g/cm2 in females and 0.635 +/- 0.087 g/cm2 in males (p < 0.01). For both sexes, the values were significantly lower compared to age-matched controls. 88% of the females and 69% of the males had T-Scores below -2.5, thus fulfilling the densitometric WHO criteria of osteoporosis. Nutritional calcium intake was similar in both sexes (804 +/- 330 mg/day in women, 738 +/- 295 mg/day in men), but lower compared to coxarthrosis patients (1080 +/- 436 mg/day). Vitamin D deficiency was prevalent in 69% of the women, and in 55%, of the men with hip fracture. In female hip fracture patients, the serum alkaline phosphatase was significantly higher (194 +/-…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 146 participants or records.
