Associação entre risco cardiovascular e hipertensão arterial em professores universitários

A hipertensao arterial e uma das mais importantes causas modificaveis de morbi-mortalidade cardiovascular precoce na populacao adulta mundial, alem de ser fator de risco independente para doencas cardiovasculares. Assim objetivou-se verificar a associacao entre indicadores de risco cardiovascular e hipertensao arterial em professores universitarios. Foram avaliados 145 professores da Universidade Federal de Vicosa (UFV), no ano de 2009, analisando-se as variaveis: sexo, idade, indice de massa corporal (IMC), relacao cintura/quadril (RCQ), circunferencia abdominal (CA), percentual de gordura (%G), colesterol total (CT), triacilglicerol (TG), glicose, pressao arterial sistolica (PAS) e diastolica (PAD) de repouso e consumo maximo de oxigenio (VO2max). Utilizou-se o teste ANOVA one way para comparacao entre individuos normotensos e pre-hipertensos e hipertensos. Calculou-se a razao de chances de desenvolvimento de quadros de PA elevada entre os individuos que apresentavam niveis indicativos de risco cardiovascular. Todos os tratamentos possuiram nivel de significância de p < 0,05. Os homens apresentaram valores significativamente maiores para idade, peso, estatura, IMC, RCQ, CA, PAS e PAD. Ja as mulheres possuiam um %G significativamente elevado. Os individuos com niveis pressoricos elevados apresentaram valores maiores para todas as variaveis, a excecao do VO2max. Observou-se associacao os fatores de risco e elevacao da PA somente para as variaveis: sexo, idade, IMC, CA, %G e TG. Conclui-se que o genero, a idade, o IMC, a circunferencia abdominal, o percentual de gordura corporal e os triacilglicerois foram considerados indicadores de risco cardiovascular por apresentarem associacao com a hipertensao arterial na amostra de professores avaliados.

Variáveis bioquímicas, antropométricas e pressóricas como indicadores de risco cardiovascular em servidores públicos

INTRODUCTION: Cardiovascular diseases have been identified as the main cause of morbidity and mortality in Brazil and in the world. OBJECTIVE: To verify the prevalence of cardiovascular factors risk (CFR) over university employees, through the use of biochemical, anthropometric and blood pressure variables. MATERIALS AND METHODS: Participated of the study 107 technical-administrative employees of Universidade Federal de Vicosa, in 2010, with the average age of 46,1 ± 10,4 years old. The analyzed parameters ware: level of body mass (BLM), waist-hip ratio (WHR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL- C) and low-density lipoprotein (LDL-C). The data analysis was to calculate the prevalence of the variables studied. For all statistical treatments was adopted p 199 mg/dL), triglycerides showed 23% of changed values (> 149 mg/dL), although the LDL-C were found 31% of values over 129 mg/dL, and 30% of evaluated showed low values of HDL-C (< 40 mg/dL). It was possible to observe that just 18.6% evaluated did not show any CFR analyzed, taking in consideration that almost half of employees are in the level of 2 to 4 CFR. CONCLUSION: It was verified an increased percentage of CFR over the university employees. Among the analyzed variables it is possible to verify that the over-weight, TC, low levels of HDL-C and high of LDL-C were the most prevalent CFR.

LEVEL OF PHYSICAL ACTIVITY IN BASIC EDUCATION TEACHERS EVALUATED BY TWO INSTRUMENTS

Cardiovascular diseases are the main causes of national death, and sedentary is an important risk factor in this degenerative process. To evaluate the level of physical activity (LPA) of teachers in the public school system of Viçosa MG by means of two distinct instruments and the agreement obtained between them. A total of 200 teachers of both genders, aged between 25 and 68, participated in this research. LPA was measured by the International Physical Activity Questionnaire (IPAQ) and through the use of a pedometer. The calculations of the prevalence of active and non-physically active individuals were performed, and the Kappa (K) index was subsequently used to establish agreement between the instruments. All analyzes were performed in MedCalc software, version 14. 10. 2 and SPSS, version 20. For the IPAQ, 70% of teachers reached adequate levels of physical activity (LPA), while by the pedometer only 26.5%. The agreement between the five categories of the pedometer and the IPAQ was not significant, as well as in the classification in active and non-active, between the instruments. In conclusion evaluating the LPA through the IPAQ it was possible to perceive that the majority of the teachers were classified as active. However, when considering the threshold of 10000 steps/day of average, using the pedometer as an instrument of evaluation of the NAF, the majority of the group cannot be considered active. In addition, there was no agreement between the instruments for the evaluation of NAF.

Obesity and association of anthropometric indicators with risk factors in teachers

The aim of this study was to verify general and central obesity, as well as the association of anthropometric indicators with cardiovascular risk factors (CvRF) in teachers of the private network of Vicosa-MG. A cross-sectional observational study was conducted with 150 teachers. Body mass index (BMI), conicity index (CI), body adiposity index (BAI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist circumference (WC), abdominal circumference (AC) and body fat percentage (%BF); systolic blood pressure (SBP) and diastolic blood pressure (DBP); glycemia (GL), total cholesterol (TC), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and triglycerides (TG) were evaluated. The prevalence of general and central obesity was calculated in addition to the simple linear regression to verify the association of anthropometric indicators between themselves and with CvRF. General and central obesity was identified in 19% and 17% of teachers respectively. The best associations between anthropometric indicators were between BMI and WHtR (R² = 0.81), WHtR and AC (R² = 0.78) and BMI and AC (R² = 0.76), all of which were positive. Between anthropometric indicators and CvRF, the best associations were found between WHtR and TG (R² = 0.25), AC and SBP (R² = 0.18) and WHR and HDL-c (R² = 0.19), the first two associations being positive and the last negative. It was concluded that approximately one in five teachers presented obesity. The general obesity indicator, BMI, was positively associated with anthropometric indicators and with most CvRF. However, central obesity indicators presented greater explanatory power on CvRF.

Anthropometric, cardiovascular and functional variables as indicators of health related physical fitness in university professors

Objective To verify the behavior of anthropometric, cardiovascular and functional variables as indicators of health-related physical fitness in university professors and perform a comparison of these variables between sexes.Materials and methods We conducted an observational epidemiological cross-sectional study in 145 professors (45.86 ± 9.7 years), 103 men (71.03%), which were evaluated by measuring heart rate (HR) and systolic (SBP) and diastolic (DBP) pressure at rest, body weight, height, body mass index (BMI), body fat percentage (BF%), handgrip strength (HGS), flexibility and cardiorespiratory fitness (CRF). We proceeded to the descriptive analysis, Student t-test for comparison between sexes and multiple regression analysis to verify the association between the variables analyzed. It was adopted a significance level of p < 0.05.Results The sex affected all variables. Women had better levels of BMI, flexibility, SBP and DBP. The BF% and CRF were associated with SBP and BMI in both sexes.Conclusion The behavior of anthropometric, cardiovascular and functional variables indicated unsatisfactory values for flexibility, HGS and BMI, with the worst levels among men. Furthermore, the variables that showed better association with HRPF were BF% and CRF.

Prevalência de dislipidemia e sua relação com consumo de oxigênio entre servidores públicos

Objective: To determine the prevalence of dyslipidemia and its relation with maximal oxygen uptake (VO2max) in public servants. Methods: Cross-sectional study conducted in 2010 with 107 technical and administrative servants of one university, by means of anthropometric measures (height and weight), submaximal treadmill test for assessment of cardiorespiratory parameter (VO2max), collection of total cholesterol (TC) and triglycerides (TG). In the statistical treatment of data, were applied the descriptive analysis, prevalence of TC, TG and VO2max, Pearson correlation and non-paired Student’s t-test. Results: The final sample comprised 101 servants (46.6 + 10.4 years old). The mean TC was 197 + 40.2mg/dl, with 51 (50.5%) presenting borderline and “high” values, and mean TG 121 + 66.6mg/dl, with 25 (24.8%) borderline and “high” values. The VO2max of 56 (55.5%) servants were classified as “Good” and 37 (36.6%) as “Excellent”. Men had a statistically significant correlation only between TG and VO2max (r= -0,45; p<0.01), whereas among the women there was correlation between TC and VO2max (r= -0.37; p<0.05). Conclusion: Dyslipidemia prevalence showed to be high in the studied population, mainly in male gender. It was found an inverse correlation between the variables TG and VO2max in men and TC and VO2max in women. However, the observed variables obtained a regular relation in the evaluated servants. doi:10.5020/18061230.2013.p290
