Non-alcoholic fatty liver disease and its associated risk factors in Brazilian postmenopausal women

Objective To evaluate the prevalence and risk factors of non-alcoholic fatty liver disease (NAFLD) in postmenopausal women.Methods A cross-sectional study was carried involving 188 women (age >= 45 years and amenorrhea >= 12 months) attending the outpatient unit in south-eastern Brazil. Exclusion criteria were liver disease (hepatitis B and C, cholestatic disease, liver insufficiency), use of drugs that affect liver metabolism; alcoholics; AIDS or cancer history; and morbid obesity. NAFLD was diagnosed by abdominal ultrasound. Clinical, anthropometric (body mass index, waist circumference) and biochemical variables were measured.Results Of the 188 women, 73 (38.8%) had NAFLD. Blood pressure, waist circumference, body mass index, LDL cholesterol, triglycerides and glucose were significantly higher in NAFLD patients when compared with women without NAFLD (control group) (p < 0.05). HOMA-IR values indicated insulin resistance only in the NAFLD group (6.1 +/- 4.6 vs. 2.4 +/- 1.4 in control group, p < 0.05). Metabolic syndrome was detected in 93.1% of the women affected by NAFLD, and 46.1% of the control group (p < 0.05). In multivariate analysis, adjusted for age and weight, the variables considered at risk for the development of NAFLD, were: high waist circumference (odds ratio (OR) 1.07, 95% confidence interval (CI) 1.01-1.13), insulin resistance (OR 3.81, 95% CI 2.01-7.13), and presence of metabolic syndrome (OR 8.68, 95% CI 3.3-24.1).Conclusion NAFLD showed a high prevalence among postmenopausal women. The presence of metabolic syndrome, abdominal obesity and IR were indicators of risk for the development of NAFLD.

Influência da composição corporal e da síndrome metabólica sobre a relação da aptidão cardiorrespiratória com o estresse inflamatório

Physical activity is associated with lower cardiovascular disease risk factors, being cardiorespiratory fitness a major component of physical activity health related. Body fatness and sarcopenia are related to sedentary lifestyle leading to proinflammatory stress and lower cadiorespiratory capacity. This study aimed correlates C-reactive protein with cardiorespiratory fitness, analyzing the influences of anthropometrics variables and metabolic syndrome (MS) presence. the cross-sectional retrospective study included baseline data of 194 adults (62 male and 132 female), 53,74 ± 8,77 years, clinically and ethically selected for a lifestyle modification program. Total cholesterol (TC) and cholesterol lipoprotein fractions, triglycerides (TG) and glucose was dosed by dry chemistry (Vitros® system, Johnson & Johnson). Blood leukocytes was quantified by automatic cell counter (Coulter ABX®, Horiba). LDL-cholesterol was obtained by Friedwald formula. Serum ultrasensitive C-reactive protein (US-CRP) was accessed by the immunochemoluminescence method (Immulite 2000®, DPC Medlab). Weight, height, body mass index (BMI) and waist circumference (WC) were measured. Muscular mass and fat mass were obtained by bioelectrical impedance analysis (impedancemeter Quantum BIA-101Q®, Clinton Township). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Balke protocol). The metabolic syndrome was diagnosed according NCEP – ATP III (2001), following recommendations of American Diabetes Association (2004). Pearson’s correlation crude and adjusted for confounders variables with p<0,05. The prevalence of MS was 30.4%. Crude correlation shows hsCRP was correlated inverse and significantly with VO2max (r= -0.21; p=-0.003) ...(Complete abstract click electronic access below)

Efeito do treinamento físico aeróbio em hipertensos de meia idade e idosos nos valores de consumo máximo de oxigênio

The aim of this study was to investigate whether aerobic capacity (VO2max) would be modified by antihypertensive therapy in elderly and middle-age women after 12 weeks of exercise training. The volunteers were divided in two groups: normotensive (n=14) and hypertensive (n=14). Aerobic exercise was performed for 3 days/week, during 60 minutes, for 12 weeks with an intensity of 50-70% rest heart hate. Anthropometric parameters (weight and height), body fat index, % of fat mass, cardiopulmonary evaluation to calculated VO2max and a cardiovascular evaluation with blood pressure and rest heart hate were evaluated at baseline and after training program. At the end of study abdominal circumference and Borg scale were also evaluated. Our findings showed the aerobic program of 12 weeks was effective to reduce diastolic blood pressure in both groups. Systolic blood pressure was reduced only hypertensive group. No evidences were found the aerobic capacity was affected by hypertensive therapies. In conclusion, the aerobic program for 12 weeks was effective to reduce blood pressure and there was no influence of antihypertensive therapy on the aerobic capacity in this particular population.

Relação entre a disparidade de força entre membros inferiores e estabilidade postural em atletas de voleibol

Volleyball is a sport in which the laterality dominant limb shows superior strength and coordination because of its preferential use. Asymmetrical tendencies during the landing after the jump when striking or blocking actions are predominant for most part of game (ARRUDA; EDUARDO, 2008). Adaptations include imbalance of forces in static and dynamic motions at the knee joint, which increases risk for injury. Also, asymmetries in balance control during jumping and landing associate with a general postural instability that can be observed during static balance tasks. The purpose of this study was to investigate relationship between unequal lower limb strength (muscle imbalance) and postural stability levels in volleyball athletes and non-athletes. Nine female volleyball athletes and 10 active non-athletes participated in this study. Four encouters with participants were scheduled: three encounters in the bodybuilding gymnasium to collect anthropometric measures (weight, height for BMI, thigh circumference, which provided an initial diagnosis about asymmetry), and to perform the isometric strength test (i.e., leg press using a load cell and a force transducer to calculate uni an bilateral strength). The last encounter was in the laboratory where a balance test on a force platform was administered under five test conditions, with three repetitions each: baseline (natural standing position), one-leg standing, right side, with full vision (D_CV), and blindfolded (D_SV), one-leg standing, left side, with full vision (E_CV), and blindfolded (E_SV). The stability levels were evaluated using the path length parameters which was based on the total displacement of the center of pressure (DTCP). . Both groups shows asymmetric strength levels between legs, with better performance for the right leg. An ANOVA three way using the DTCP for the CV condition, legs (D x E), trials (3) with repeated measures for the first two factors and with a between (three)...

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.

Presença de fatores de risco dependentes ou não de esforço físico em praticantes de corrida de rua

In order to reduce the sedentarism and to improve population's health condition, many physical activity incentive programs have been stimulated. As a result, many people have adhered to street racing, but their health condition is almost always ignored. The aim of this study was to evaluate street racers' health condition, identifying the presence of cardiovascular risk factors as well as problems associated to street racing. The study case was composed by 111 racers from the town of Bauru (94 men and 17 women) aged in average 39±13 years old, who were evaluated in 4 street race competitions. The subjects answered to an anamnesis with questions about their socioeconomic status, medicine use, cardiovascular risk, physical exercise practices, and issues related to racing and injury. Weight (kg) and height (m) were measured to calculate the body mass index (BMI, kg/m²) as well as systolic and diastolic blood pressure (BP), heart rate (HR), abdominal circumference (AC), and flexibility. It could be observed that the majority of racers were Caucasian, married and belonged to social classes over C. The prevalent age was between 18 and 35 years old (42%). Among the participants, 38.7% have already undergone some kind of surgery and 13% declared having some health problem. The questionnaire pointed out that 36% had low and moderate cardiovascular risk. It could be noticed from the AC that 10% of men and 18% of women had high cardiac risk. Among the tested, 43.2% (24.3% altered and 18.9% borderline) showed high BP on the day of the test, but only 2.7% had self-declared hypertensive. In relation to injury, 36% had already had lesions of some kind, 27.5% of which had occurred in the last 8 months. 66.6% had derived from training or racing competitions and the knee was the mostly affected body part. Only 43% had professional orientation by a physical education teacher during their training and the main reasons for them to begin racing practice were...
