Abstract
We assessed the lumbar bone mineral density (BMD), body mass index (BMI), height, and weight of 800 people (400 men and 400 women aged between 31 and 50 years). All were teachers. The results obtained were as follows: The age, height, BMI, and weight were the same as the previous study.The BMD increased incrementally with the distal level through the lumbar spine (L2 to L4).The average BMD of the women was greater than the men's.The men's average BMD of the L2 was clearly higher than that of the women's (the women's BMD was 0.94, and men's BMD was 0.99 (p<0.05)).On the contrary, the men's average BMD of the L4 was clearly lower (the women's BMD was 1.056, and men's BMD was 1.027 (p<0.05)).
