Women especially will lose bone rapidly after the menopause, which can lead to osteopenia initially, with worsening to osteoporosis and an increased propensity to fracture. Statistics from the USA show approximately 1.5 million fractures occurring each year as a consequence of osteoporosis. The steep increase in the elderly population of Taiwan in recent decades, similar to Western developed nations, will further emphasize the urgency of preventative strategy against osteoporosis. Although there have been studies on the bone mineral density (BMD) of Taiwanese women, these studies, however, were mainly cross-sectional in nature. In order to investigate reproductive and lifestyle risk factors or protective factors for bone loss in the postmenopausal years and avoid the shortcomings of a cross-sectional study design, this longitudinal community-based cohort study with a 2-year follow-up were carried out. We include 397 postmenopausal women as study subjects until the end of the second year. Using a questionnaire, baseline characteristics (age, years of education, etc.), lifestyle characteristics (ever smoked, drink alcohol, physical activity level, etc.), reproductive history (age at menarche and menopause, parity and number of livebirths, breastfeeding, etc.), as well as pertinent medical and family history were recorded. Anthropometric measurements were taken of each subject (height, weight, BMI, waist-hip ratio (WHR), etc.). Every subject received dual energy X-ray absorptiometry (DEXA) measurements of BMD ( bone mineral density) for the lumbar spine and left hip and total body fat distribution. The data collected during the first year here will be used as baseline to compare with any weight, height, lifestyle and BMD changes 1 and 2 years later. Part of these original data were shown in appendix. The only problem we encounter during the first and second year study is SARS episode, which hindered subjects from receiving DEXA exam at hospital. Hence the subject number enrolled is less than originally planned.application/pdf185416 bytesapplication/pdfzh-TW國立臺灣大學醫學院一般醫學科骨密度停經世代追蹤研究危險因子bone mineral density (BMD)menopausecohort studyrisk factor[SDGs]SDG3journal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/22634/1/922314B002330.pdf
