AbstractBackground and Aims: The aim of the present study was to investigate the relationship between visceral fat area (VFA), estimated by bioimpedance, and cardiovascular risk factors independent of BMI and waist circumference in a cohort of Romanian patients. Material and Methods: This was a cross-sectional study, in which were collected data from 751 patients ≥18 years of age from Cluj-Napoca. Anthropometric, biochemistry, body composition and medical history parameters were recorded from patients’ files. Results: Compared with the participants with VFA <100 cm2, those with VFA ≥100 cm2had significantly worse levels of the laboratory parameters describing the glycemic metabolism, lipid metabolism and liver functions (p <0.05 for all). A higher percentage of participants with VFA ≥100 cm2had diabetes, obesity, hypertension, hypertriglyceridemia and hypo-HDL cholesterolemia (p <0.05 for all). VFA was correlated with systolic and diastolic blood pressure, total and LDL-cholesterol levels, triglycerides, ALT, previous diagnosis of diabetes, hypertriglyceridemia and hypo-HDL cholesterolemia independent of BMI and waist circumference. Conclusions: Among this cohort of Romanian adults, an increasing level of visceral adiposity was correlated with worse lipid and glucose metabolism parameters as well as with increased levels of ALT, which probably reflects liver fat deposition.

Abstract Background A significant positive association was found in previous studies among obesity, visceral fat accumulation, and hyperuricemia. The purpose of this study was to explore the association between the ratio of visceral fat area to leg muscle mass (VFA-to-LMM) and hyperuricemia, and verify the role of gender differences in the association. Methods A total of 3393 (43.3% are men) participants from Tianjin Union Medical Center-Health Management Center were recruited for this cross-sectional study. The VFA-to-LMM ratio was used as the independent variable. Hyperuricemia, a serum uric acid level ≥ 416 μmol/L in men and in menopausal women and ≥ 357 μmol/L in premenopausal women, was used as the dependent variable. Multiple logistic regression analysis was used to estimate the odds ratio and the 95% confidence interval between the VFA-to-LMM ratio and hyperuricemia. Results The overall prevalence of hyperuricemia was 14.8% (8.9% in women, and 22.5% in men). After adjustment by age, smoking status (for males), menopause status (for females), drinking status, exercise frequency, blood pressure, alanine aminotransferase, fasting plasma glucose, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, creatinine, and history of diseases, a strong positive association was found between the VFA-to-LMM ratio and hyperuricemia in both men (4th vs. 1st quartile 1.60, 95%CI: 1.03–2.49) and women (4th vs. 1st quartile 5.22, 95%CI: 2.44–12.56). After additional adjustment by BMI, there was still a significant positive association in women (4th vs. 1st quartile 2.57, 95%CI: 1.06–6.77). The results of subgroup analysis showed that pre-menopausal women (4th vs. 1st quartile OR: 3.61) have a higher risk of hyperuricemia than postmenopausal women (4th vs. 1st quartile OR: 1.94) with the increase of the VFA-to-LMM ratio. Besides, the interaction analysis results showed the highest risk of hyperuricemia when VFA and LMM were both in the highest quantile (OR: 11.50; 95% CI: 4.86–31.98). Conclusion The VFA-to-LMM ratio was positively associated with the risk of hyperuricemia in women after adjustment by confounders. Pre-menopausal women have a higher risk of hyperuricemia than postmenopausal women with the increase of the VFA-to-LMM ratio. In addition, the highest risk of hyperuricemia was demonstrated when both VFA and LMM were at the highest quartile.

Abstract Background: Previous studies have found a significant positive association between obesity, visceral fat accumulation and hyperuricemia. The purpose of the study was to explore the association between the ratio of visceral fat area to leg muscle mass(VFA-to-LMM) and hyperuricemia, and verify the role of sex differences in the association.Methods:In this cross-sectional study, a total of 3393 (43.3% for men) participants from Tianjin Union Medical Center-Health Management Center were recruited. Body composition were measured by multielectrode bioelectrical impedance analyzer. The VFA-to-LMM ratio was used as independent variable. Hyperuricemia, defined as a serum uric acid level ≥ 416 μmol/L in men and menopausal women, and ≥ 357 μmol/L in premenopausal women, was used as the dependent variable. Multiple logistic regression analysis was used to estimate the odds ratio and 95% confidence interval between VFA-to-LMM ratio and hyperuricemia.Results:The overall prevalence of hyperuricemia was 14.8%, and the prevalence of hyperuricemia in women (8.9%) was significantly lower than that in men (22.5%). After adjustment for age, smoking status (for males), menopause status (for females), drinking status, exercise frequency, blood pressure, alanine aminotransferase, fasting plasma glucose, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, creatinine, and history of diseases, a strong positive association was observed between VFA-to-LMM ratio and hyperuricemiain bothmen (4th vs. 1st quartile 1.60, 95%CI: 1.03-2.49) and women (4th vs. 1st quartile 5.22, 95%CI: 2.44-12.56).After additionally adjustment for BMI, there was still a significant positive association in women (4th vs. 1st quartile 2.57, 95%CI: 1.06-6.77), while the association disappeared in men(4th vs. 1st quartile 0.97, 95%CI: 0.55-1.70).Conclusions:The VFA-to-LMM ratio was positively associated with the risk of hyperuricemia in women after adjustments for confounders. In addition, the highest risk of hyperuricemia was observed when both VFA and LMM were at the highest quartile. However, well-controlled prospective studies are needed to further confirm the causality between VFA-to-LMM ratio and hyperuricemia.

ObjectivesTo assess the prevalence of disabilities (vision, hearing, mobility, cognitive, self-care and communication) and non-communicable diseases (NCDs) among the elderly population in two districts in Telangana, India.DesignPopulation-based cross-sectional study using a cluster random sampling method to select the study clusters.SettingElderly population in Khammam and Warangal districts were recruited. Detailed interviews were conducted by trained community health workers. Personal and demographic information such as age, gender, level of education and a self-report of NCDs was collected. The Washington Disability Questionnaire was administered to assess the presence of disabilities.Participants1821 participants aged ≥60 years, 54.5% were women, and 73.3% had no education.Primary outcome measurePrevalence of disabilities and NCDs.ResultsOverall, the prevalence of at least disability was 20.3% (95% CI 16.3 to 24.9). The prevalence of self- reported disabilities were: seeing (5.9%; 95% CI 4.4 to 7.8), mobility (12.8%; 95% CI 9.7 to 16.8), hearing (3.6%; 95% CI 2.7 to 4.8), cognition (4.8%; 95% CI 3.5 to 6.7), self-care (3.3%; 95% CI 2.3 to 4.7) and communication (1.8%; 95% CI 1.2 to 2.6). Overall, the prevalence of at least one NCD was 34.2% (95% CI 30.9 to 37.7). Hypertension was the most common systemic condition (25.4%; 95% CI 22.4 to 28.7), followed by diabetes (9.0%; 95% CI 7.3 to 11.0), and body pains (muscle-skeletal) (9.9%; 95% CI 8.1 to 12.2).ConclusionEvery fifth elderly person in the districts of Khammam and Warangal in Telangana had at least one self-reported disability. Besides, a third of the elderly had at least one NCD. There is a definite need to develop comprehensive public health strategies to address disabilities and NCDs in Telangana.
