Association between anthropometric indicators of body fat and metabolic risk markers in post-menopausal women

Objective. to evaluate anthropometric indicators of body fat and their association with metabolic risk markers in postmenopausal women.Methods. A cross-sectional study with 80 Brazilian women (40-70 years) was carried out. Body mass index (BMI = weight/height(2)), waist circumference (WC) and waist-to-hip ratio (WHR) were obtained for anthropometric evaluation. Trunk fat mass (TFM) was measured by dual-energy X-ray absorptiometry. The following metabolic variables were evaluated: total cholesterol (TC), HDL, LDL, triglycerides (TG), as well as glycemia and insulin to determine insulin resistance (HOMA-IR).Results. Overweight and obesity were observed in 81% of the women. Values of WC >88 cm were observed in 68.5% of the women. on average, TC, LDL and TG levels were above normal levels in 60, 50 and 42.5% of the women, respectively; and HDL was normal in 82.5%. IR was observed in 37.5% of the women. Positive correlations were found between anthropometric indicators and TFM (P < 0.05). WC was most correlated with TFM (r = 0.92), followed by BMI (r = 0.88) and by WHR (r = 0.48; P < 0.05). All anthropometric indicators and TFM showed significant negative correlations with HDL and significant positive correlations with HOMA-IR (P < 0.05). Only WHR was significantly associated with dysglycemia (R(2) = 12%), hypertriglyceridemia (R(2) = 17%) and decreased HDL (R(2) = 27%). WC was significantly associated with HOMA-IR (R(2) = 34%).Conclusion. WC and WHR are anthropometric measures that showed strong correlation with TFM and with metabolic risk markers in postmenopausal women.

Respiratory muscle strength in obese individuals and influence of upper-body fat distribution

CONTEXTO E OBJETIVO: A disfunção pulmonar no obeso pode estar associada a comprometimento muscular respiratório e também pode ser influenciada pelo predomínio de distribuição de gordura corporal na região toraco-abdominal. O objetivo foi avaliar a força dos músculos respiratórios em obesos e analisar a influência da distribuição do tecido adiposo. TIPO DE ESTUDO E LOCAL: Estudo transversal no período pré-operatório de Cirurgia Bariátrica. Estudo desenvolvido no Programa de Pós-Graduação em Bases Gerais da Cirurgia da Universidade Estadual Paulista (Unesp) - Faculdade de Medicina de Botucatu. MÉTODO: Mensuração da força dos músculos respiratórios através das medidas das pressões inspiratórias e expiratórias máximas (PImax e PEmax) em obesos candidatos à cirurgia bariátrica. Avaliar a distribuição do tecido adiposo através da relação entre as circunferências da cintura e quadril (RC/Q). Comparar esses atributos com os valores de referência de normalidade e também entre grupos com diferentes índices de massa corpórea (IMC). RESULTADOS: Foram avaliados 23 homens e 76 mulheres. Todos foram submetidos à avaliação de PImax e 86 realizaram a PEmax. O IMC médio foi de 44,42 kg/m². Os valores de PImax e de PEmax estavam dentro dos padrões de normalidade, a relação cintura-quadril mostrou distribuição do tecido adiposo na porção superior corporal e não houve correlação entre as variáveis estudadas. CONCLUSÃO: Na população de obesos estudada, o excesso de peso não provocou alterações na força dos músculos respiratórios, e as modificações não foram influenciadas pela distribuição de gordura predominante em porção superior corporal.

Simultaneity of the anthropometric markers of adiposity and chronic diseases in women

Aim. The aim of this paper was to investigate the relationship between the accumulation of different anthropometric indicators and the prevalence of some chronic diseases in women over 40 years of age. Methods. The sample was comprised of 562 women between 40 and 95 years of age (64.5 ± 11.4) attended by the research projects were carried out in two cities in southeastern Brazil. Anthropometric measurements were taken: weight, height, waist circumference, hip circumference, and the values of BMI and WHR were later calculated. The referenced morbidity questionnaire was also applied, based on the Standard Health Questionnaire (SHQ), which analyzes the presence of degenerative chronic diseases in the adult population. For the statistical treatment, the chi-square and binary logistic regression tests were performed, with significance set at 5%. Results. The relationship between three changes in the anthropometric indicators and the greater incidence of diseases continued significant for hypertension (OR=3.77 [95% CI: 2.14-6.65], =P=0.001), and for endocrine and metabolic diseases (OR=2.59 [95%: 1:47 to 4:32], =P=0.001), regardless of the effects of age and physical activities. Conclusion. The simultaneity of body fat indicators is more strongly associated with the prevalence of some chronic diseases (hypertension, endocrine, and metabolic), relative to the individualized use of anthropometric indicators.

Energy and fat intake are not associated with abdominal adiposity

Background and objective: Central or abdominal obesity (AA) is a highly prevalent determinant of the metabolic syndrome and its control requires intervention strategies. This study investigated the risk factors associated with the presence of AA in hospitalized individuals. Patients and methods: A total of 1626patients were studied. The investigated risk factors possibly associated with AA were gender, age, body mass index (BMI), habitual energy intake (HEI) and fat intake (FI). AA was determined by waist circumference (WC) and waist-to-hip ratio (WHR). The chi2, Mann-Whitney and Kruskal-Wallis tests were used to compare the data and univariate and multiple logistic regressions were used to identify the predictive factors of AA. Results: Women were at higher risk of developing AA than men (P. <. 0.0001). The HEI and FI of individuals with and without AA and of women and men were not significantly different. According to multivariate analysis, HEI was not a predictive factor of AA, contrary to gender and age. The risk factors for AA, determined by WC, were gender (OR. = 6.8; CI. = 5.3-8.7) and age (OR. = 1.0; CI. = 1.0-1.0). Women were six times more likely to develop AA than men. Conclusions: Evidence of an association between AA and HEI or FI was not found, but gender and age were associated with AA. © 2013 Elsevier Masson SAS.

Predictive capacity of anthropometric indicators for abdominal fat in the oldest old

Cardiovascular diseases are a growing public health problem that affects most people over the age of 65 years and abdominal obesity is one of the risk factors for the development of these diseases. There are several methods that can be used to measure body fat, but their accuracy needs to be evaluated, especially in specific populations such as the elderly. The aim of this study was to assess the accuracy of anthropometric indicators to estimate the percentage of abdominal fat in subjects aged 80 years or older. A total of 125 subjects ranging in age from 80 to 95 years (83.5 ± 3), including 79 women (82.4 ± 3 years) and 46 men (83.6 ± 3 years), were studied. The following anthropometric indicators were used: body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and waist-to-height ratio (WHtR). The percentage of abdominal fat was measured by DEXA. Sensitivity and specificity were analyzed using an ROC curve. The sensitivity, specificity and AUC were 0. 578, 0. 934 and 0. 756 for BMI, respectively; 0.703, 0.820 and 0.761 for WC; 0.938, 0.213 and 0.575 for WHR, and 0.984, 0.344 and 0.664 for WHtR. BMI and WC were the anthropometric indicators with the largest area under the curve and were therefore more adequate to identify the presence or absence of abdominal obesity.
