Objectives : To define the bone status and pattern of bone loss in a normal adult popula-
tion living in a rural area of Khon Kaen province.
Study design : A descriptive study.
Settings : Department of Medicine, Faculty of Medicine, Khon Kaen University, Thailand.
Subjects : 436 subjects (181 men and 255 women), aged 20-80 years.
Main Outcome Measures : Bone parameter including total bone mineral density (BMD),
the bone mineral density at different sites such as forearm, lumbar spine and hip, bone mineral con-
tent (BMC) were measured by dual energy X-ray absorptiometry (DEXA).
Results : The result revealed that women had lower bone mass at various bone sites than
men. The peak bone mass in women was observed between 30-39 years of age except at the distal
radius which occurred between 20-29 years of age while the peak bone mass in men was observed
between 20-29 years of age.
It
was also shown that bone loss occurred in both men and women
with advancing age. The rate of decline at all sites in women was greater than men especially when
they were over 60 years old. When comparisons were made between pre and post-menopausal
women, the mean of bone mineral density in pre-menopausal women was 1.18เธ‘0.08, 0.69เธ‘0.06,
0.69เธ‘0.06, 1.0เธ‘0.13, 1.15เธ‘0.13 g/cm

women was 1.02เธ‘0.12, 0.54เธ‘0.11, 0.54เธ‘0.11, 0.75เธ‘0.16, 0.88เธ‘0.2 g/cm
