comparisons of percentage Body Fat Body mass index waist circumference and waist stature ratio in adults
The American Journal of Clinical Nutrition, 2009Co-Authors: Katherine M Flegal, John A Shepherd, Anne C Looker, Barry I Graubard, Lori G Borrud, Cynthia L Ogden, Tamara B Harris, James E Everhart, Nathaniel SchenkerAbstract:Background: Body mass index (BMI), waist circumference (WC), and the waist-stature ratio (WSR) are considered to be possible proxies for adiposity. Objective: The objective was to investigate the relations between BMI, WC, WSR, and percentage Body Fat (measured by dual-energy X-ray absorptiometry) in adults in a large nationally representative US population sample from the National Health and Nutrition Examination Survey (NHANES). Design: BMI, WC, and WSR were compared with percentage Body Fat in a sample of 12,901 adults. Results: WC, WSR, and BMI were significantly more correlated with each other than with percentage Body Fat (P < 0.0001 for all sex-age groups). Percentage Body Fat tended to be significantly more correlated with WC than with BMI in men but significantly more correlated with BMI than with WC in women (P < 0.0001 except in the oldest age group). WSR tended to be slightly more correlated with percentage Body Fat than was WC. Percentile values of BMI, WC, and WSR are shown that correspond to percentiles of percentage Body Fat increments of 5 percentage points. More than 90% of the sample could be categorized to within one category of percentage Body Fat by each measure. Conclusions: BMI, WC, and WSR perform similarly as indicators of Body Fatness and are more closely related to each other than with percentage Body Fat. These variables may be an inaccurate measure of percentage Body Fat for an individual, but they correspond fairly well overall with percentage Body Fat within sex-age groups and distinguish categories of percentage Body Fat.

Body Fat distribution as a risk factor of endometrial cancer.
The journal of obstetrics and gynaecology research, 2000Co-Authors: Akiko Iemura, Tsutomu Douchi, Shinako Yamamoto, Nobuyuki Yoshimitsu, Yukihiro NagataAbstract:Objective: To investigate the relative contributions of upper Body Fat distribution and overall adiposity to endometrial cancer risk. Methods: Subjects were 63 postmenopausal women with endometrial cancer aged less than 70 years and 201 age-matched controls. Age, age at menopause, years since menopause, height, weight, and Body mass index were recorded at the time of admission. The trunk-leg Fat ratio, Body Fat mass, trunk Fat mass, and the percentage of Body Fat were measured by dual-energy X-ray absorptiometry. Results:Trunk-leg Fat ratio was higher in endometrial cancer patients than in controls (1.40 + 0.59 vs 1.23 + 0.39, p < 0.05). Whereas, other variables including age at menopause, percentage of Body Fat, Body Fat mass, and Body mass index did not differ between the 2 groups. On stepwise multiple regression analysis, the trunk-leg Fat ratio was still correlated with the presence of endometrial cancer (p < 0.05). Conclusions: Upper Body Fat distribution rather than overall adiposity is associated with endometrial cancer risk.

Possible association of Body-Fat distribution with preeclampsia.
The journal of obstetrics and gynaecology research, 1997Co-Authors: Hirofumi Ijuin, Tsutomu Douchi, Sachiko Nakamura, Toshimichi Oki, Schinichi Yamamoto, Yukihiro NagataAbstract:Objective: To investigate whether preeclampsia is associated with Body-Fat distribution. Methods: Twenty-two patients with preeclampsia (mean age: 31.9 ± 6.0 years) and 126 controls without preeclampsia (mean age: 30.9 ± 5.2 years) were enrolled in this study. We compared baseline characteristics and 4 Body-Fat indices measured by DEXA on Day 5 postpartum. The possible correlation between the variables and the development of preeclampsia was evaluated by multivariate analysis. Results: The Body-Fat ratio, the upper-half Body-Fat amount, upper-half-Body Body-Fat amount ratio, and upper-/lower-half-Body Body-Fat amounts ratio on Day 5 postpartum were significantly higher in the preeclampsia group. However, the upper-/lower-half-Body Body-Fat amount ratio was best correlated with preeclampsia among variables in multivariate analysis. Conclusion: Upper-Body-Fat distribution might be associated with the development of preeclampsia.

Correlation of Body Fat Distribution with Grade of Endometrial Cancer
Gynecologic oncology, 1997Co-Authors: Tsutomu Douchi, Hirofumi Ijuin, Sachiko Nakamura, Toshimichi Oki, Kuninori Maruta, Yukihiro NagataAbstract:Abstract To elucidate whether Body Fat distribution correlates with the grade of endometrial cancer, we studied 74 postmenopausal women with endometrial cancer (mean age 62.4 ± 6.6 years, range 49–78 years). The subjects were divided into three groups as follows: well-differentiated adenocarcinoma (G1 group; N = 53), moderately differentiated adenocarcinoma (G2 group; N = 11), and poorly differentiated adenocarcinoma (G3 group; N = 10). Four Body Fat indices [total Fat weight (g), Body Fat ratio (%), trunk Fat weight (g), and weight ratio of trunk Fat to leg Fat (trunk/leg ratio)] were measured by dual-energy X-ray absorptiometry. Baseline characteristics and Body Fat indices in the three groups were compared. In all subjects, the correlations of these variables with the grade of adenocarcinoma were investigated using single and stepwise regression analyses. Total Fat weight, Body Fat ratio, and trunk Fat weight showed slight increases with the grade of differentiation. The trunk/leg ratio in G1 group was significantly higher than in G2 and G3 groups. The trunk/leg ratio was significantly correlated with the grade in stepwise regression analysis. Body Fat distribution in women with endometrial cancer may correlate with the grade of the adenocarcinoma.

The Relation between Body‐Fat Distribution and Lipid Metabolism in Postmenopausal Women
The journal of obstetrics and gynaecology research, 1996Co-Authors: Tsutomu Douchi, Hirofumi Ijuin, Sachiko Nakamura, Toshimichi Oki, Shinichi Yamamoto, Mari Katanozaka, Yukihiro NagataAbstract:Objective: To evaluate the relationship between Body-Fat distribution and lipid metabolism in postmenopausal women. Methods: Fifty-four women (mean: 61.8 ± 7.8 years old) showing hyperlipidemia and 63 controls were enrolled in this study. Their baseline characteristics and Body-Fat indices, as measured by DEXA, were compared. The correlations between the serum-lipid levels and the variables were evaluated. Results: The amount of upper-half-Body Fat and the Body-Fat ratio were significantly higher in the hyperlipidemia group. In single-regression analysis, there were low levels of correlation between the serum TC levels and the amount of upper-half- Body Fat and the upper-Body Fat ratio. There was a low level of correlation between the serum TG level and the amount of upper-half-Body Fat, the upper-lower-half- Body-Fat ratios, and the upper-half-Body-Fat ratio. After adjusting for variables, the serum TC and TG levels best correlated with the amount of upper-half-Body-Fat (r = 0.458, r = 457, respectively). Conclusion: In postmenopausal women, lipid metabolism is reflected in the amount of upper-half-Body Fat, irrespective of age and the Body-mass index (BMI).

Body Fat distribution in women with polycystic ovary syndrome
Obstetrics & Gynecology, 1995Co-Authors: Tsutomu Douchi, Sachiko Nakamura, Toshimichi Oki, Hirofumi Huin, Shinichi Yamamoto, Yukihiro NagataAbstract:Objective: To investigate Body Fat distribution in women with polycystic ovary syndrome (PCOS). Methods: Body weight, Body mass index (BMI), and six indices of Body Fat measured by dual-energy x-ray absorptiometry were compared in 40 women with PCOS and 97 age-matched controls. The possible correlations between the Body Fat characteristics and serum androgen levels were evaluated in the 40 PCOS women. Body Fat distribution was classified into upper- ( N = 24) and lower-half Body type ( N = 16), and androgen levels and the incidence of hirsutism were compared in the two types. Results: The BMI, Body Fat ratio, upper-half Body Fat ratio, and upper-half/lower-half Body Fat ratio were significantly higher in PCOS women than in controls. After adjustment for age, height, and Body weight, the upper-half/lower-half Body Fat ratio was still significant ( P r = 0.607, P r = 0.585, P P P Conclusions: Serum DHEA-S levels seem to be associated with upper-half Body Fat distribution in women with PCOS, irrespective of Body weight.
