Abstract
Osteoporosis is a major public health concern of the 21st century due to the rapidly increasing elderly population worldwide. 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 toWestern 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 395 postmenopausal women who are older than 65 years as study subjects.
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 . Up to now, totally 303 patient finished the follow-up examination. Sixty of than took antiresorptive drug during follow-up period.
The data collected initially were used as baseline to compare with any weight, height, lifestyle and BMD changes 2 years later. The final data analyzed were listed as tables in the following. 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.
