(Revista Brasileira de Educação Física e Esporte, 2011-08-04) Moreira, Osvaldo Costa; Oliveira, Renata Aparecida Rodrigues de; Andrade Neto, Flávio; Amorim, William; Oliveira, Cláudia Eliza Patrocínio; Doimo, Leonice Aparecida; Amorim, Paulo Roberto dos Santos; Laterza, Mateus Camaroti; Monteiro, Walace David; Marins, João Carlos Bouzas
A hipertensão arterial é uma das mais importantes causas modificáveis de morbi-mortalidade cardiovascular precoce na população adulta mundial, além de ser fator de risco independente para doenças cardiovasculares. Assim objetivou-se verificar a associação entre indicadores de risco cardiovascular e hipertensão arterial em professores universitários. Foram avaliados 145 professores da Universidade Federal de Viçosa (UFV), no ano de 2009, analisando-se as variáveis: sexo, idade, índice de massa corporal (IMC), relação cintura/quadril (RCQ), circunferência abdominal (CA), percentual de gordura (%G), colesterol total (CT), triacilglicerol (TG), glicose, pressão arterial sistólica (PAS) e diastólica (PAD) de repouso e consumo máximo de oxigênio (VO2máx). Utilizou-se o teste ANOVA one way para comparação entre indivíduos normotensos e pré-hipertensos e hipertensos. Calculou-se a razão de chances de desenvolvimento de quadros de PA elevada entre os indivíduos que apresentavam níveis indicativos de risco cardiovascular. Todos os tratamentos possuíram nível de significância de p < 0,05. Os homens apresentaram valores significativamente maiores para idade, peso, estatura, IMC, RCQ, CA, PAS e PAD. Já as mulheres possuíam um %G significativamente elevado. Os indivíduos com níveis pressóricos elevados apresentaram valores maiores para todas as variáveis, à exceção do VO2máx. Observou-se associação os fatores de risco e elevação da PA somente para as variáveis: sexo, idade, IMC, CA, %G e TG. Conclui-se que o gênero, a idade, o IMC, a circunferência abdominal, o percentual de gordura corporal e os triacilgliceróis foram considerados indicadores de risco cardiovascular por apresentarem associação com a hipertensão arterial na amostra de professores avaliados.
Beneficial effects of physical activity in an HIV-infected woman with lipodystrophy: a case report
(Journal of Medical Case Reports, 2011-09-05) Mendes, Edmar Lacerda; Andaki, Alynne Christian Ribeiro; Natali, Antônio José; Amorim, Paulo Roberto dos Santos; Oliveira, Leandro Licursi de; Paula, Sérgio Oliveira de; Brito, Ciro José; Córdova, Cláudio; Mutimura, Eugene
Lipodystrophy is common in patients infected with human immunodeficiency virus receiving highly active antiretroviral therapy, and presents with morphologic changes and metabolic alterations that are associated with depressive behavior and reduced quality of life. We examined the effects of exercise training on morphological changes, lipid profile and quality of life in a woman with human immunodeficiency virus presenting with lipodystrophy. A 31-year-old Latin-American Caucasian woman infected with human immunodeficiency virus participated in a 12-week progressive resistance exercise training program with an aerobic component. Her weight, height, skinfold thickness, body circumferences, femur and humerus diameter, blood lipid profile, maximal oxygen uptake volume, exercise duration, strength and quality of life were assessed pre-exercise and post-exercise training. After 12 weeks, she exhibited reductions in her total subcutaneous fat (18.5%), central subcutaneous fat (21.0%), peripheral subcutaneous fat (10.7%), waist circumference (WC) (4.5%), triglycerides (9.9%), total cholesterol (12.0%) and low-density lipoprotein cholesterol (8.6%). She had increased body mass (4.6%), body mass index (4.37%), humerus and femur diameter (3.0% and 2.3%, respectively), high-density lipoprotein cholesterol (16.7%), maximal oxygen uptake volume (33.3%), exercise duration (37.5%) and strength (65.5%). Quality of life measures improved mainly for psychological and physical measures, independence and social relationships. These findings suggest that supervised progressive resistance exercise training is a safe and effective treatment for evolving morphologic and metabolic disorder.

(Revista Paulista de Pediatria, 2018-10) Miranda, Valter Paulo Neves; Morais, Núbia Sousa de; Faria, Eliane Rodrigues de; Amorim, Paulo Roberto dos Santos; Marins, João Carlos Bouzas; Franceschini, Sylvia do Carmo Castro; Teixeira, Paula Costa; Priore, Silvia Eloiza
To evaluate the association of body image with physical activity level, body composition, and sedentary behavior (SB) of female adolescents. Exploratory cross‑sectional study conducted with 120 female adolescents aged between 14‑19 years, from the city of Viçosa, Minas Gerais, Southeast Brazil. Body image was evaluated with a Body Silhouette Scale (BSS) and a Body Shape Questionnaire (BSQ). Weight, height, and waist circumference values were analyzed, as well as the waist‑to‑height ratio and body fat percentage. The physical activity level (PAL) was assessed by 24‑hour Physical Activity Recall and SB by screen time, that is, time spent in front of a TV, playing video game, on the computer and using tablets, and, separately, the cell phone time. Mean age was 16.5± 1.5 years, and most adolescents were eutrophic (77.6%), sedentary/low PAL (84.2%), with high screen time (85.2%) and cell phone time (58.7%). Body dissatisfaction was stated in 40.6% of BSQ and 45.8% of BSS evaluations. Body distortion was identified in 52.9% of participants. All body composition measures, along with cell phone time and PAL, were associated with body dissatisfaction, the more active adolescents presenting higher levels of dissatisfaction. This study concluded that female adolescents with higher cell phone time also present higher body dissatisfaction, as well as the most physically active ones. All body composition measurements were associated with body dissatisfaction, mainly body mass index, waist circumference, and waist‑to‑height ratio.
Effects of different exercise programs and minimal detectable changes in hemoglobin A1c in patients with type 2 diabetes
(Diabetology & Metabolic Syndrome, 2016-02-16) Lade, Carlos Gabriel de; Marins, João Carlos Bouzas; Lima, Luciana Moreira; Carvalho, Cristiane Junqueira de; Teixeira, Robson Bonoto; Albuquerque, Maicon Rodrigues; Reis, Janice Sepúlveda; Amorim, Paulo Roberto dos Santos
The incidence of diabetes mellitus is increasing worldwide, resulting in a global epidemic. The most common type, the type 2 diabetes mellitus, constitutes of 90–95 % of the cases and is characterized by the action of and/or impaired insulin secretion. Regular exercise is a recommended strategy in several studies and guidelines for type 2 diabetes control and complications associated with it. Therefore, we evaluated and compared the effects of aerobic and strength exercise programs on the glycemic control in patients with type 2 diabetes. The selected patients were divided into groups which performed moderate strength training (ST) and aerobic training (AT). The study lasted 20 weeks and was divided into two 10 week phases with anthropometric (body mass index, waist, abdomen and hips circumferences, waist/hip ratio) and biochemical (glycemic and lipid profile) assessments at baseline, 10 weeks and 20 weeks. For intra and inter analyses a mixed ANOVA model was used. Individual changes were calculated using the minimum detectable change, based on a 90 % confidence interval. Eleven patients (five men and six women) completed the 20 weeks of training; five from the ST group and six from the AT. No significant changes were observed in any anthropometric variable in either group. Statistically significant differences were found in mean hemoglobin A1c in both groups between baseline (AT: 8.6 ± 2.5; ST: 9.2 ± 1.9) and 10 weeks (AT: 7.2 ± 1.7; ST: 7.9 ± 1.2) (p = 0.03), and baseline (AT: 8.6 ± 2.5; ST: 9.2 ± 1.9) and 20 weeks (AT: 7.5 ± 1.7; ST: 7.4 ± 0.9) (p = 0.01). For the minimal detectable changes, 40 % of the ST and 33 % of AT achieved these changes for hemoglobin A1c. Both aerobic and strength exercises can help the metabolic control in patients with type 2 diabetes, even without significant changes in anthropometry over the 20 weeks of training. However, this period was sufficient to cause changes in hemoglobin A1c values and the estimated average glucose, which are important parameters in controlling diabetes, thus signaling an important consequence of adhering to an exercise routine for type 2 diabetic patients.

(BMC Public Health, 2019) Miranda, Valter Paulo Neves; Amorim, Paulo Roberto dos Santos; Bastos, Ronaldo Rocha; Souza, Vitor Gabriel Barra; Faria, Eliane Rodrigues de; Franceschini, Sylvia do Carmo Castro; Priore, Silvia Eloiza
Lack of regular physical activity, high sedentary behavior and presence of unbalanced alimentary practices are attitudes associated with an inadequate lifestyle among female adolescents.To assess the lifestyle of female adolescents based on measurements of behavioral variables.Cross-sectional study with 405 female adolescents between 14 and 19 years old, resident and attending public schools in Viçosa (state of Minas Gerais). Their lifestyle was analyzed by the Physical Activity Recall, number of steps, screen time (ST), cellphone time (CT), sitting time, food frequency questionnaire (FFQ), and alcohol and tobacco consumption. With multiple correspondence analysis it was possible to observe dispersion and approximation of the variables’ categories. Latent class analysis (LCA) was used for modeling the “lifestyle” variable, having been conducted in the poLCA (Polychromous Variable Latent Class Analysis) package of the R statistical software.The mean age was 15.92 ± 1.27 years. Most of the adolescents were considered physically inactive (78%) and with low number of steps (82.57%); 41.45% reported not performing Moderate to Vigorous Physical Activities (MVPA) adequately. Sedentary behavior was found high when assessing ST (72.90%) and CT (65.31%). It was found the best fitted latent class model for the lifestyle (p-G2 = 0.055, p-χ2 = 0.066) featured three latent classes and one covariate (alcohol): Class 1, ‘Inactive and Sedentary’ (γ = 77.5%); Class 2, ‘Inactive and Non-sedentary lifestyle (γ=16.31%); and Class 3, ‘Active and sedentary’ (γ=6.19%). Female adolescents that had ‘never consumed alcohol’ were 2.26 times as likely (log OR = 0.8174; p = 0.033) to belong to class 3 (Active & Sedentary lifestyle) than to class 1 (Inactive & Sedentary lifestyle).Latent class analysis model with five manifest variable (MVPA, number of steps, ST, sitting time and number of meals) and alcohol consumption like covariate showed itself to be an accurate and objective method in the assessment of female adolescents’ lifestyle. Female adolescents that had ‘never consumed alcohol’ were more as likely to belong to class ‘Active & Sedentary lifestyle’ than to class Inactive & Sedentary lifestyle. An inactive and sedentary lifestyle is coupled to other unhealthy behaviors during adolescence, possibly carrying over into adult life.
Fatores associados ao comportamento sedentário em escolares de 9-12 anos de idade
(Motriz: Revista de Educação Física, 2013-05-10) Amorim, Paulo Roberto dos Santos; Santos, Amanda; Andaki, Alynne Christian Ribeiro; Mendes, Edmar Lacerda
São recentes os estudos que investigaram impactos do comportamento sedentário (CS) sobre a saúde, principalmente em crianças. O objetivo foi investigar fatores associados ao CS em escolares do município de Uberaba, MG. Trata-se de estudo epidemiológico, transversal, com amostra probabilística (n = 649). Foram coletadas e consideradas variáveis independentes: medidas antropométricas, pressão arterial, exames bioquímicos, tempo gasto em atividade física (AF). CS foi considerado variável dependente, caracterizado pelo tempo de tela (TT), e verificado fatores associados pela regressão de Poisson. Meninas apresentaram valores maiores de dobras cutâneas, triglicerídeos e HDL-c e meninos, maior concentração de glicose sanguínea, atenderam mais à recomendação de 60 min de AF/dia e maior CS. O TT > 2 h/dia foi prevalente em 76,9 % da amostra. CS não foi associado a variáveis sociodemográficas, de saúde e comportamentais em crianças de 9-12 anos de idade. Mais pesquisas são necessárias para elucidar as inter-relações complexas entre TT e fatores associados.
Metabolic syndrome prevalence in elderly of urban and rural communities participants in the HIPERDIA in the city of Coimbra/MG, Brazil
(Investigación y Educación en Enfermería, 2015-04-15) Paula, Josiane Aparecida Teixeira de; Moreira, Osvaldo Costa; Silva, Cristiano Diniz da; Silva, Diogo Santos; Amorim, Paulo Roberto dos Santos
To identify the prevalence of metabolic syndrome (MS), and the influence of gender and place of residence for elders served by the Family Health Strategy in the municipality of Coimbra (Minas Gerais state, Brazil). The sample consisted of 435 individuals of both sexes, with mean of age 72 ± 8 years. Women had higher prevalence rates of MS (urban= 40%, rural= 37%) with differences (p<0.05, φ= 0.168 and 0.284) for men (urban= 13%, rural= 22%). Odds Ratio for SM was significant in age groups over 65 years in urban areas, with women having higher chances compared with men (OR=3.07 times), becoming 5.8 times aged 75 to 79 years. Women are more exposed to obesity (urban= 80.4 %, rural= 78.6%) than men, regardless of place of residence (p<0.05, φ=0.46 and 0.47 respectively), and the urban women are still exposed to hypertension (65%, p= 0.022, φ= 0.12). The prevalence of MS and exposure to risk factors such as obesity and hypertension was higher in women, mainly in urban areas. Health professionals, like nurses, should note that the elderly population in urban areas have greater exposure to risk factors for MS, which should strengthen educational programs that promote healthy lifestyles.
Prevalence of obesity and association of body mass index with risk factors in public school teachers
(Revista Brasileira de Cineantropometria e Desempenho Humano, 2015-11-17) Oliveira, Renata Aparecida Rodrigues de; Mota Júnior, Rômulo José; Tavares, Debora Dornelas Ferreira; Moreira, Osvaldo Costa; Lima, Luciana Moreira; Amorim, Paulo Roberto dos Santos; Britto, Raquel Rodrigues; Marins, João Carlos Bouzas
The objective of this study was to determine the prevalence of overweight and obesity and the association of body mass index (BMI) with cardiovascular risk factors in public school teachers. A cross-sectional study was conducted on 200 basic education teachers from Viçosa, MG. We assessed BMI, waist circumference (WC), waist-hip ratio (WHR), body fat percentage (%BF), systolic and diastolic blood pressure, fasting glucose, total cholesterol, high-density and low-density lipoprotein (LDL-C), triglycerides, and number of daily steps. Linear regression was used to evaluate the associations between BMI (independent variable) and the other variables (dependent variable). Overweight was observed in 58% of the teachers and obesity in 20%. Among women, all risk factors differed significantly between the group with overweight and/or obesity and the group classified as normal BMI, except for total cholesterol and LDL-C. Linear regression analysis showed a positive association between BMI and the other anthropometric measurements, blood pressure, and biochemical parameters; however, after adjustment for age, an association was only observed with the anthropometric variables (WC, WHR, and %BF). The prevalence of overweight/obesity was high among the basic education teachers studied. The overall obesity indicator (BMI) was not associated with cardiovascular risk factors when adjusted for age.

(Revista Brasileira em Promoção da Saúde, 2013-01-14) Amorim, William; Oliveira, Renata Aparecida Rodrigues de; Breguez, Michelle Silveira; Amorim, Paulo Roberto dos Santos; Marins, João Carlos Bouzas
Determinar a prevalência de dislipidemia em servidores públicos e sua relação com o consumo máximo de oxigênio (VO2máx). Estudo transversal, realizado em 2010, com 107 servidores técnico-administrativos de uma universidade, através de medidas antropométricas (estatura e peso), teste de esteira submáximo para avaliação do parâmetro cardiorrespiratório (VO2máx), coleta de colesterol total (CT) e triglicerídeos (TG). Utilizou se, no tratamento estatístico dos dados, a análise descritiva, o cálculo das prevalências de CT, TG e VO2máx, a correlação de Pearson e o teste t de Student não pareado. A amostra final compreendeu 101 servidores (46,6 + 10,4 anos). Os avaliados obtiveram média de CT 197+ 40,2mg/dl, com 51 (50,5%) apresentando valores limítrofes e “altos”, e média de TG 121+66,6mg/dl, com 25 (24,8%) valores limítrofes e “altos”. O VO2máx de 56 (55,5%) avaliados foi classificado como “Bom” e 37 (36,6%) como “Excelente”. Os homens obtiveram correlação estatisticamente significante apenas entre TG e VO2máx (r = - 0,45; p<0,01), enquanto, entre as mulheres, a correlação foi do CT com VO2máx (r = - 0,37; p<0,05). Conclusão: A prevalência de dislipidemias se mostrou elevada na população estudada, principalmente entre o sexo masculino. Encontrou-se uma correlação inversa entre as variáveis TG e VO2máx nos homens e entre CT e VO2máx nas mulheres. Contudo, as variáveis em questão obtiveram uma relação regular nos servidores avaliados
Risk factors for cardiovascular disease in professors from a public university
(Investigación y Educación en Enfermería, 2013-10-07) Moreira, Osvaldo Costa; Oliveira, Renata Aparecida Rodrigues de; Oliveira, Cláudia Eliza Patrocínio; Doimo, Leonice Aparecida; Amorim, Paulo Roberto dos Santos; Laterza, Mateus Camaroti; Monteiro, Walace David; Marins, João Carlos Bouzas
To determine the prevalence of risk factors for cardiovascular disease among professors of a public university. This cross-sectional study included 145 professors from the Federal University of Viçosa (UFV), MG, Brazil, in 2010. Analyzed variables included age, weight, height, waist, hip and abdominal circumferences, in addition to total cholesterol, triglycerides, glucose, and resting systolic and diastolic blood pressures. A total of 71% were men, the average age of the men was higher than that of the women (46.9 versus 43.2 years old); half of the participants were overweight (46.9% were overweight and 9.0% were obese). Other factors were: 17.2% presented a waist-hip ratio at risk; 46.9% had greater than normal abdominal circumference; 4.0% presented high total cholesterol, 20.2% high triglycerides, 4.8% of the individuals presented abnormal glucose metabolism; and 16.6% were hypertensive. In comparison with men, women presented lower systolic blood pressure, diastolic blood pressure, body mass index, and abdominal, hip and waist circumferences. There was a trend of increased waist/hip and abdominal circumferences, total cholesterol, triglycerides, and systolic blood pressure as individuals aged. The college professors addressed in this study present important risk factors for cardiovascular disease. Hence, prevention and control measures need to be implemented in order to reduce the problem, a process in which nursing professionals play a key role in the achievement of success.
Swimming training attenuates contractile dysfunction in diabetic rat cardiomyocytes
(Arquivos Brasileiros de Cardiologia, 2010-12-21) Silva, Márcia Ferreira da; Pelúzio, Maria do Carmo Gouveia; Amorim, Paulo Roberto dos Santos; Lavorato, Vitor Neiva; Santos, Natália Pereira do; Bozi, Luiz Henrique Marchesi; Penitente, Arlete Rita; Falkoski, Daniel Luciano; Berfort, Felipe Gomes; Natali, Antonio Jose
Experimental diabetes promotes contractile dysfunction in cardiomyocytes, but the effects of swimming in this disorder are not known. To test the effects of a swimming training program (STP) on cardiomyocyte contractile dysfunction in rats with experimental diabetes. Wistar rats (age: 30 days; mean body weight: 84.19 g) with diabetes induced by streptozotocin (60 mg/kg body weight; glucose > 300 mg/dl) were divided into sedentary diabetic rats (SD, n = 10) and exercised diabetic rats (ED, n = 13). Animals of same age and weight served as sedentary controls (SC, n = 10) and exercised controls (EC, n = 06). Animals and ED and EC underwent a STP (05 days/week, 90 min/day) for 08 weeks. Left ventricular (LV) myocytes were isolated and electrically stimulated at 3.0 Hz at room temperature (∼ 25º C). Diabetes reduced contractile function in cardiomyocytes of animals compared to controls (i.e., lower amplitude of contraction, longer duration of contraction and relaxation). The STP attenuated the reduced amplitude of contraction (SC, 11 ± 0.2% vs ED, 11.6 ± 0.2%), time to peak contraction (SC, 319 ± 5.8 ms vs ED, 333 ± 4.8 ms) and time to 50.0% of relaxation (SC, 619 ± 22.2 ms vs ED 698 ± 18.6 ms) of cardiomyocytes of diabetic rats. Diabetes reduced the size of cardiomyocytes, however, the STP minimized the reduction of cell volume and width, without changing length. The swimming training program attenuated the contractile dysfunction of the LV myocytes of rats with experimental diabetes.
Treinamento físico para indivíduos HIV positivo submetidos à HAART: efeitos sobre parâmetros antropométricos e funcionais
(Revista Brasileira de Medicina do Esporte, 2013-01) Mendes, Edmar Lacerda; Andaki, Alynne Christian Ribeiro; Amorim, Paulo Roberto dos Santos; Natali, Antonio José; Brito, Ciro José; Paula, Sérgio Oliveira de
The use of highly active antiretroviral therapy (HAART) has improved the prognosis of HIV-infected individuals. However, HAART has been associated with the development of metabolic and fat distribution abnormalities, known as HIV-associated lipodystrophy syndrome (HIVALS). This study investigated the impact of 24 weeks of resistance exercise with aerobic component (REAC) on anthropometric and functional parameters in HIV-infected patients undergoing HAART. Ninety- nine HIV-infected patients were randomly allocated into four groups: exercise and lipodystrophy (n = 24; EX + LIP); exercise without lipodystrophy (n = 21; EX + NoLIP); control and lipodystrophy (n = 27; NoEX + LIP); control without lipodystrophy (n = 27; NoEX + NoLIP). Subjects from exercised groups (EX+LIP and EX+NoLIP) participated in a 24-week REAC program. Anthropometric, strength and cardiorespiratory fitness tests were assessed at baseline and 24 weeks after intervention. Body circumferences (P < 0.0001) and waist-hip ratio (P = 0.017) changed after 24 weeks of REAC in both exercised groups. The sum of seven skinfolds assessed, body fat percentage, body fat mass, total fat, central fat and peripheral subcutaneous fat reduced (P < 0.0001) in response to REAC. Lean body mass increased (P < 0.0001) in exercised groups, regardless of the outcome (LIP or NoLIP). Strength and cardiorespiratory fitness increased (P < 0.0001) in both exercised groups in response to REAC. 24 weeks of REAC prevented the manifestation of changes arising from HIVLDS and contributed to their reduction.
