Résumé
Objective To describe the regional and population-related differences in calcaneus bone mineral density (BMD) across ten regions of China.Methods Based on the results from the second Re-survey of China Kadoorie Biobank project,in which 5％ of the surviving participants were interviewed during 2013-2014 and 24 677 participants aged 38-87 years were included in the study.We excluded those people with missing data for BMD and important variables.Calcaneus BMD was measured using the quantitative ultrasound bone densitometer.We analyzed four indexes,including broadband ultrasound attenuation (BUA),speed of sound (SOS),stiffness index (SI),and T score.Results The average calcaneus BMDs of the present population were:BUA (109.7 ± 12.6) dB/MHz,SOS (1 554.7 ± 45.6) m/s,SI (88.3 ± 18.8),T score (-0.74 ± 1.28).Urban residents showed higher calcaneus BMD,so as in men.The calcaneus BMD decreased by age,with a larger decline seen in women.Current smokers and postmenopausal women presented lower calcaneus BMD,while in those who frequently drank milk or yogurt or being physically more active,had higher calcaneus BMD.Conclusion Calcaneus BMD varied greatly among people from the ten regions of CKB study and among participants having different demographic characteristics,lifestyle behaviors or health conditions.

Résumé
OBJECTIVES: The objective of this study was to examine associations between nutrient intake, food habit, and bone mineral density in college females. MATERIAL AND METHODS: The study evaluated 83 female college students from the city of Daegu. A self-report questionnaire was used to collect data on participants' nutrient intake and food habits. All subjects gave written informed consent. All participants were given instructions, by a dietitian on how to complete the questionnaire on food intake (inclusive of beverages) and food habit record of weekdays. SONOST-2000 (Ultrasonic Bone mineral density Meter, Osteosis, Korea) was used to measure calcaneus bone density. Body composition was determined by using Inbody3.0 (Biospace, Korea) analysis.
