Abstract:
BACKGROUND:Bone mineral density(BMD) is still regarded as the standard of early diagnosis and treatment of osteoporosis(OP) at present.But it is found in detection that different sex,age and skeleton location have different OP detection rate,so it is necessary to analyze the difference. OBJECTIVE:To compare the difference of OP detection rate at different skeleton location between males and females with the increase of age. DESIGN:A cross-sectional study taking patients as the subjects. SETTING:Endocrine department of an artillery general hospital of Chinese PLA. PARTICIPANTS:A total of 147 patients,including 54 males and 93 females, aged from 50 to 78 years old,who were hospitalized in our outpatient clinic from September 2000 to January 2002,were selected and divided into 3 groups according to age,50 to 59 years old group (n=46,13 males and 33 females),60 to 69 years old group (n=66,26 males and 40 females) and 70 to 79 years old group (n=35,15 accordance with the OP diagnostic criteria recommended by WHO[1]. Exclusive criterion: secondary OP patients caused by chronic disease of liver,kidney, heart, and gastrointestinal tract and some endocrine disease such as diabetes,hyperthyroidism and so on. INTERVENTIONS:Every subject filled in the history questionnaire in detail.Height and body mass were measured accurately and body mass index(BMI) was calculated (kg/m2).A new type of Norland Excell plus dual-energy X-ray absorptiometry(DEXA) was used to detect BMD(g/cm2) of L2- 4 and proximate femur(neck of femur, Ward's triangle,greater trochanter).The detected values were compared with the normal data of young adults of the same sex and the T value(SD) was obtained. RESULTS:OP in lumber vertebra was predominant in female climacteric(χ 2=10.14,P< 0.01),and the detection rate of OP in lumber vertebra and neck of femur increased with age(χ 2=7.41, P< 0.05).OP in simple neck of femur increased significantly in males after 60 yeas old(χ 2=9.11,P< 0.05). Females were more liable to suffer from OP in simple lumber vertebra and in both lumber vertebra and neck of femur(χ 2=8.04,P< 0.05;χ 2=14.26,P< 0.01).Age had significant negative correlation with BMD in neck of femur,Ward's triangle and great trochanter of females(r=- 0.364,- 0.389, P< 0.01;r=- 0.504,P< 0.001),while BMI was positively correlated with L2- 4,neck of femur and great trochanter significantly(r=0.306,0.329,0.338,P< 0.05). CONCLUSION:Detection rate of OP changes with skeleton detecting location and age.It is very significant to recognize and evaluate these objective phenomena correctly for the diagnosis and treatment of OP.
