Abstract

This study is to evaluate the factors that affect to the bone mineral density(BMD) of postpartum women by comparing BMD between postpartum and general women who are ages from 20 to 39, and to identify correlation between various factors weight, height, body mass index(BMI), hemoglobin(Hb) and BMD. Study subjects were postpartum(n=159) and general(n=180) women. We checked the BMD of femoral neck and lumbar spine by using dual energy X-ray bone densitometry. The mean age was $30.69{\pm}3.32$ in postpartum care group and $31.22{\pm}5.66$ in general women group. In postpartum care group, the mean BMD of femoral neck and lumbar spine were -0.187 and -0.076. In general women group, the mean BMD of femoral neck and lumbar spine were -0.029, and -0.169. According to BMI level, each group was divided into two subgroups. One was 23 or more BMI subgroup, and the other was under 23 BMI subgroup. There was a significant difference in BMD of femoral neck and lumbar spine between two subgroups in general women group, but only a significant difference in BMD of lumbar spine is noted between two subgroups of postpartum group. According to Hb level, each group was divided into two subgroups. One was 11g/dl or more subgroup, and the other was under 11g/dl subgroup. There was not a statistically significant difference of BMD in all subgroups. BMD of femoral neck and lumbar spine showed a significant correlation with weight, height, BMI in both groups. There was a significant correlation between BMD and Hb level in postpartum care group, but a significant correlation was not noted in general women group. The postpartum women showed a significant correlation between BMD and various factors such as weight, height, BMI just like in general women. There was a significant correlation between BMD and Hb in postpartum women, but not in general women.

20대와 30대의 출산 후 여성과 일반 여성들을 대상으로 골밀도에 영향을 주는 요인을 알아보기 위해 신장, 체중, 체질량지수, 헤모글로빈과 골밀도를 비교하였다. 2006년 1월부터 7월까지 출산 후 산모 159명과 일반여성 180명이었다. 산모군 대퇴경부 골밀도 평균 -0.187, 요추 골밀도 -0.076이었다. 일반군 대퇴경부 골밀도 평균 -0.029, 요추 골밀도 -0.169이었다. 체질량지수 23 기준에서 일반군 23 이상 군과 23 이하 군 간에 대퇴경부와 요추에서 유의한 차이가 있었으나(p<0.05), 산모군 에서는 요추에서만 두 군간 차이가 있었다. 헤모글로빈수치 11을 기준으로 한 집단 간 분류에서는 산모군과 일반군 모두에서 유의한 차이가 없었다. 산모군과 일반군 모두에서 대퇴경부 및 요추의 골밀도는 체중, 신장, 체질량지수와 매우 유의한 상관관계가 있었다(p<0.01). 산모군에서 골밀도 대퇴경부 및 요추에서 매우 유의한 상관관계를 보였으나, 일반군의 골밀도 대퇴경부 및 요추에서 헤모글로빈과 상관관계가 없었다. 산모군은 일반군과 마찬가지로 체중, 신장, BMI가 BMD와 유의한 상관관계가 있으며(p<0.01), 일반군에서 골밀도는 헤모글로빈과 상관관계가 없었으나, 산모군에서는 BMD와 유의한 상관관계를 보였다(p<0.01).
