Abstract

Objectives: Study to investigate osteoporosis status in postmenopausal women. Subjects and methods: A cross-sectional descriptive study was conducted on 212 postmenopausal female patients visiting medical Tuyen Quang Provincial General Hospital. The patients lumbar spine bone density and femoral neck were measured using the DEXA method on the DEXXUM T machine manufactured by Osteosys, South Korea. Osteoporosis diagnosis was based on the World Health Organization's diagnostic criteria, using the T-score index: T-score ≤ -2.5 SD indicates osteoporosis, severe osteoporosis accompanied by osteoporotic fractures. Results: The study group had a prevalence of osteoporosis at the femoral neck of 37.7% and at the lumbar spine of 67%. There was 73,1% of the patients having osteoporosis in at least one of the two locations. Risk factors associated with osteoporosis include age, duration of menopause, body mass index, and having given birth to more than two children. We estimated that the hip bone density decreases by around - 0,066 g/cm² per year, while the decrease at the lumbar spine is approximately -0,006 g/cm² annually. Conclutions: The prevalence of osteoporosis among postmenopausal female patients examined in Tuyen Quang Provincial General Hospital is relatively high, accounting for 73,1%. Among these cases, spinal osteoporosis is 1.8 times more prevalent (67%) compared to hip osteoporosis (37,7%). Several factors are associated with the prevalence of osteoporosis, including age, duration of menopause, number of childbirths, and body mass index. Currently, there is no observed correlation between osteoporosis and ethnicity, geographical region, and physical activity level
