Association between risk factors of osteoporosis and bone mineral density in women of different ethnic groups in a Malaysian hospital

Abstract

Risk factors of osteoporosis need to be identified for prevention of osteoporosis. However, studies on the risk factors of osteoporosis in the Malaysian population are lacking. The study aimed to determine the relationship between potential risk factors of osteoporosis and hip BMD of postmenopausal women in a Malaysian tertiary hospital setting. A cross-sectional study was carried out on 76 postmenopausal women, who were scheduled for Dual-energy X-ray Absorptiometry (DXA) scan at UKM Medical Centre (UKMMC) from February to May, 2014. Interview sessions using structured questionnaire were conducted to obtain information on social demographic and potential risk factors of osteoporosis. The DXA scan results of the hip BMD for all the respondents were recorded to determine the association between the potential risk factors of osteoporosis and hip BMD. In this study, 44.7% of patients had normal hip BMD measurement (T score >-1.0), while 55.3% had low hip BMD measurement (T score 0.05) between hip BMD and family history of osteoporosis, lifestyle activities and smoking. Parity, habitual tea consumption and BMI were positively associated with hip BMD, whereas duration of sleep was negatively associated with hip BMD among postmenopausal women in UKMMC.
