The present study was carried out to investigate the influence of lifestyle on bone mineral density (BMD) and bone turnover among young women in Chiang Mai, Thailand. A total of 177 young women affiliated with Chiang Mai University hospital were enrolled. Firstly, Questionnaires about their lifestyle and the Osteoporosis Knowledge Test (OKT) were examined. The measurement of BMD was assessed by Quantitative Ultrasound (QUS). Secondly, Based on the measurement of BMD, the subjects were divided into 2 groups, a Low BMD group (L group: less than YAM-1.0SD) and a Normal BMD group(N group: more than YAM-1.0SD) L group (n= 23) and N group (n= 23) were examined using Osteocalcine (OC), type 1 collagen cross-linked N-telopeptide (NTx) and undercarboxylated osteocalcin (ucOC) as bone turnover markers, and serum Ca, 1,25-(OH)2VitaminD, VitaminK1 and Vitamin K2(MK-4) as bone turnover related factors. Based on the results, the percentage of Low BMD group was 23.2%. Concerning lifestyle and BMD, the BMD of the low cheese intake group was 99.7±17.0 and the BMD of the high cheese intake one was 110.0±23.3 (p < 0.05). The BMD of the fracture experience group was 82.5±11.6 and the BMD of no-fracture group was 103.3±19.6 (p < 0.05). There were significant differences in ucOC and 1,25-(OH)2VitaminD between L and N groups (p < 0.05). It was suggested that BMI, food and fracture experience might affect BMD level and suppression of bone formation might have contributed to the low BMD group among young women in Chiang Mai, Thailand.
