Coffee Consumption and Bone Mineral Density in Korean Premenopausal Women

Abstract

BackgroundAlthough Asian people are known to have lower bone mass than that of Caucasians, little is known about coffee-associated bone health in Asian. This study aimed to assess the relationship between coffee consumption and bone mineral density (BMD) in Korean premenopausal women.MethodsData were obtained from the Fourth Korea National Health and Nutrition Examination Survey 2008-2009. The study population consisted of 1,761 Korean premenopausal women (mean age 36 years) who were measured for lumbar spine and femoral neck BMD and who completed a standardized questionnaire about coffee intake frequency. We excluded the participants who took hormone replacement therapy or medication for osteoporosis. The cross-sectional relationship between coffee consumption and impaired bone health (osteopenia or osteoporosis) was investigated by bone densitometry.ResultsCoffee consumption showed no significant association with BMD of either femoral neck or lumbar spine, independent of other factors. The adjusted odds ratios for BMD for those who consumed once in a day, twice a day and three times a day were 0.94 (0.70-1.26), 0.93 (0.67-1.28), and 1.02 (0.69-1.50), respectively (P for trend = 0.927).ConclusionThis study does not support the idea that coffee is a risk factor for impaired bone health in Korean premenopausal women.

Coffee Consumption Might Reduce the Risk of Osteopenia/Osteoporosis in Premenopausal Taiwanese Women

“…However, premenopausal women were excluded from the study. Another study showed no significant association between coffee consumption and bone mineral density of either the femoral neck or lumbar spine among Korean premenopausal women [16,17]. Similarly, a study exploring how someone's smoking and coffee consumption habits in the premenopausal stage could affect the postmenopausal bone mineral density showed no significant effect [24].…”

“…Notwithstanding, preventive factors of premenopausal osteoporosis should be identified to avoid damages that might occur later in life. There are controversies regarding the effects of coffee consumption on osteoporosis [17,18,19,20,23]. In a recent study, coffee consumption was protective against osteoporosis in postmenopausal Korean women [17].…”

“…Several studies have been carried out to assess the relationship between coffee drinking and osteopenia or osteoporosis. Nonetheless, the results have been inconsistent [17,18,19,20]. For instance, the consumption of 600 mL or more of coffee per day was associated with an increased osteoporotic fracture risk in Swedish women [19].…”

Caffeine Influences Functional Activity and Gene Expression of Bone Marrow Osteoblastic Cells from Osteoporotic Rats

“…13 It is known, for example, that regular coffee intake may prevent type 2 diabetes and cardiovascular disease; however, it can promote detrimental effects when consumed in higher doses. 14,15 One study investigated the effect of daily caffeine intake and bone quality on healthy postmenopausal women and did not observe any bone changes in this study population. 16 A daily administration of 20 mg caffeine for 4 weeks increased bone mineral density of the tibia of ovariectomized rats 17 and did not affect the skeletal parameters of rats with streptozotocin-induced disorders.…”

Knowledge Level and Awareness About Calcium Deficiency, Vitamin D Deficiency and Osteoporosis Among Physical Therapy and Rehabilitation School Students

“…Kafeinin, kalsiyum absorbsiyonunu azaltabileceği ve günlük 330 mg. kafein tüketiminin kırık riskinde artış ile ilişkili olduğu bulunmuştur (23). Bir başka çalışmada fazla kahve tüketiminin kemik yoğunluğunu bir miktar azalttığı, ancak kırık riskini artıracak nispette osteoporotik bir duruma neden olmadığı bildirilmektedir (24). Çalışma grubunun %83'ü kahve tükettiğinden osteoporoz açısından risk altındadır.…”
