The Relationship

The aim of the study was to investigate in premenopausal women whether the relationship between percentage body fat (PBF) and body mass index (BMI; in kg/m2) differs between Korean Asians (Ko-As) living in Seoul, South Korea, and Caucasians (Ca) living in New York City. Healthy premenopausal women (50 Ko-As; 38 Ca), ages 22–50 yr, were studied. Weight, height, and PBF by dual-energy X-ray absorptiometry were measured. Total body dual-energy X-ray absorptiometry data were collected using GE-Lunar systems (Prodigy-Korea and DPXL-New York), and all scan analyses were performed by one technician in New York. Similar soft tissue phantoms were used for daily instrument calibrations at both sites. The relationship between PBF and BMI was assessed by multiple regression analysis with race, age, reciprocal of BMI (1/BMI), and a race-by-age interaction as the final independent variables. Race ( P = 0.003) and 1/BMI ( P < 0.001) were significantly related to PBF in this model. A significant race-by-age interaction ( P = 0.039) indicated that the slope of the lines for PBF vs. age differed between Ko-As and Ca. This study demonstrates in a Ko-As sample that the BMI-fat relationship differs significantly from that in a comparable group of Caucasian women. Investigators who use BMI as an index of fatness should be aware of the well documented differences in the relationship of BMI and fatness across race/ethnic groups.

Background: Accelerated decline of bone mass occurs in women after the menopause, and might lead to excessive bone resorption and eventually to osteoporosis. To find out the changes of bone mineral density (BMD) before and after menopause, the shown was undertaken. Materials and Methods: This comparative study was conducted in the Department of Medicine, Sylhet M A G Osmani Medical College Hospital, Sylhet during July 2008 to June 2009. Forty postmenopausal women; monthly income and BMI matched 40 premenopausal women were selected according to inclusion and exclusion criteria. BMD of lumber vertebrae and femoral neck was determined using Dual energy x-ray absorptiometry (DXA) method (Norland XR 46, Pencil beam). Results: The parity of the postmenopausal women was significantly higher than that of premenopausal women (6.9 ± 2.6 vs 3.1± 1.5; p<0.01). The body weight was significantly lower in postmenopausal women than that of premenopausal women (54.1 ± 8.3 kg vs 61.0 ± 9.7 Kg; p<0.01). The height was significantly lower in postmenopausal women than premenopausal women (148.2 ± 5.7cm vs 153.4 ± 6.4cm; p<0.01). The BMD was lower in postmenopausal women than premenopausal women in lumber vertebrae (0.68 ± 0.13 gm/cm2 vs 0.94 ± 0.03 gm/cm2; p <0.01) and also in femoral neck (0.63 ± 0.12 gm/cm2 vs 0.84 ± 0.14 gm/cm2; p < 0.01). A significant positive correlation was present between BMD and height (r=0.512; p<0.05); and weight (r=0.489; p<0.05); and a negative correlation between BMD and age (r=-0.408; p<0.05); parity (r=-0.456; p<0.05) and years since menopause (r=-0.350; p<0.05). Conclusion: The BMD was significantly lower in postmenopausal women than that of premenopausal women and negative correlation was present between BMD and age, parity and years since menopause.   DOI: http://dx.doi.org/10.3329/bjmed.v22i1.13592 Bangladesh J Medicine 2011; 22: 1-7

The International Society for Clinical Densitometry (ISCD) convenes a Position Development Conference (PDC) to make recommendations for standards in the field of bone densitometry. This year 2019 the new official positions in pediatric bone health were published. Topics considered included relevant technical and clinical issues for dual energy X-ray absorptiometry (DXA), other bone evaluation technologies other than central DXA and the evaluation of vertebral fractures. In addition to the utility of the lumbar spine and total body less head, this year the recommendations add the utility of DXA in peripheral sites in children and adolescents.
