The Relationship of Hand Grip Strength with Bone Mineral Density and Vitamin D in Postmenopausal Women

Abstract

Amaç: Bu çalışmanın amacı postmenopozal kadınlarda el kavrama gücünün (EKG) kemik mineral yoğunluğu (KMY) ve D vitamin seviyeleri ile ilişkisini değerlendirmektir. Gereç ve Yöntem: Çalışmaya 131 postmenopozal kadın alındı. EKG Jamar el dinamometresi ile ölçüldü. KMY dual enerji X-ray absorbsiyometri ile lomber omurga ve femur boyun bölgelerinden ölçüldü. Serum 25-hidroksivitamin D (25OHD) seviyeleri tespit edildi. Bulgular: Hastaların yaş ortalaması 61,2±9,2 yıl idi. Ortalama EKG 22,9 kg idi ve 32 hasta (%24,4) düşük EKG'ye sahipti. Otuz yedi hasta (%28,2) osteoporotik, 62 hasta (%47,3) osteopenikti. Ortalama 25OHD düzeyi 17 ng/mL idi ve 101 hasta (%77,1) D vitamin yetersizliğine sahipti. Osteoporoz, osteopeni ve normal KMY'ye sahip gruplar arasında EKG bakımından anlamlı farklılık vardı (p=0,016). EKG değerleri lomber omurga ve femur boyun kısımlarındaki T skorları ve KMY değerleri ile pozitif korelasyon (p<0,001, r=0,340; p<0,001, r=0,300; p<0,001, r=0,320; p=0,001, r=0,298 sırasıyla), yaş ve menopoz süresi ile negatif korelasyon (p<0,001, r=-0,344; p<0,001, r=-0,318 sırasıyla) gösterdi. Ancak, EKG ve 25OHD seviyeleri arasında herhangi bir ilişki bulunmadı (p=0,860; r=0,016). Sonuç: Osteoporoz tanısı olan postmenopozal kadınlar, normal KMY'ye sahip postmenopozal kadınlardan daha düşük EKG'ye sahiptir ve EKG bu toplumda KMY ile ilişkili iken, D vitamin ile ilişkili değildir. Postmenopozal kadınlardaki osteoporoz risk yönetiminde hastalar kas gücünün artırılması yönünde teşvik edilmelidirler. Anahtar kelimeler: Kas gücü, el kavrama gücü, kemik mineral yoğunluğu, D vitamin Objective: The aim of the present study was to evaluate the relationship of hand grip strength (HGS) with bone mineral density (BMD) and vitamin D levels in postmenopausal women. Materials and Methods: One hundred thirty one postmenopausal women were included in this study. HGS was measured by Jamar hand dynamometer. BMD was measured by dual energy X-ray absorptiometry at lumbar spine and femoral neck sites. Serum 25-hydroxyvitamin D (25OHD) levels were measured. Results: The mean age of patients was 61.2±9.2 years. The mean HGS was 22.9 kg and 32 patients (24.4%) had low HGS. Thirty seven patients (28.2%) were osteoporotic and 62 (47.3%) were osteopenic. The mean 25OHD level was 17 ng/mL and 101 (77.1%) patients having vitamin D insufficiency. There was a significant difference in HGS values among groups with osteoporosis, osteopenia, and normal BMD (p=0.016). HGS values demonstrated a positive correlation with T-scores and BMD values at lumbar spine and femoral neck sites (p<0. 001, r=0.340; p<0.001, r=0.300; p<0.001, r=0.320; p=0.001, r=0.298, respectively) and negative correlation with age and duration of menopause (p<0.001, r=-0.344; p<0.001, r=-0.318; respectively). However, no significant association was observed between 25OHD levels and HGS (p=0.860, r=0.016). Conclusion: Postmenopausal women with osteoporosis had lower HGS than postmenopausal women with normal BMD, and HGS was significantly correlated with BMD, but not with vitamin D ...

Association of Modifiable Risk Factors with Bone Mineral Density among People with Distal Radius Fracture: A Cross-Sectional Study

“…Previous research has identified the association of balance impairment with low BMD among postmenopausal women. 42,66 Recently, Mehta and colleagues established a high reliability for the timed up-and-go test to assess functional balance among patients with DRF (with a mean age of 62.6 [SD 7.6] y). 60 This is likely a more feasible test for clinical implementation than the Biodex data we used for our research purposes.…”

“…This might be due to the fact that older population were prone to have fracture at low BMD-prone area such as the hip, proximal humerus, and vertebrae 87. According to Serdaroğlu Beyazal et al, HGS test score was significantly correlated with BMD, as postmenopausal women with osteoporosis had a lower HGS test score than postmenopausal women with normal BMD 88…”
