ABSTRACT

A obesidade é uma condição clínica cuja prevalência aumenta progressivamente e que está cada vez mais associada à morbi-mortalidade cardiovascular. A concentração visceral de gordura aumenta tal risco, portanto, a medida da cintura abdominal, de forma a evidenciar obesidade abdominal, torna-se necessária e tão importante quanto o índice de massa corporal (IMC). Nosso objetivo foi determinar a prevalência de obesidade e obesidade abdominal e sua associação com os fatores de risco cardiovasculares. Uma amostra de pacientes assistidos no Ambulatório de Medicina Integral foi analisada quanto: idade, sexo, IMC, cintura e as presenças de diabetes mellitus tipo 2, hipertensão arterial, dislipidemia, síndrome metabólica (SM), tabagismo e sedentarismo. Foram selecionados 119 pacientes, todos com aferição do IMC e cintura, entre 50 ±13,4 anos, sendo 89% mulheres. A prevalência de obesidade e de obesidade abdominal foi de 44% e 66%, respectivamente. A obesidade e a obesidade abdominal estão associadas à presença de SM (p=0,01; OR=3,42 e p=0,0005, OR=7,55), e entre si (p<0,0001, OR=22,1). A determinação da cintura foi um teste sensível (89.5%) e com bom valor preditivo negativo (80%) para o diagnóstico de SM em nossos pacientes. As prevalências de obesidade e obesidade abdominal foram altas. A obesidade e a obesidade abdominal estão associadas com a SM. A cintura elevada é um marcador sensível para o diagnóstico de SM, corroborando a importância da sua medida na prática clínica.


Obesity is a progressively prevalent clinical condition increasingly associated with mortality and morbidity from cardiovascular diseases. Visceral fat accumulation worsens such risk and for that reason measuring the waist circumference as a way for evidencing Abdominal Obesity is considered as necessary and important as calculating the Body Mass Index (BMI). The objective of this study is to determine the prevalence of obesity and abdominal obesity and associate them with cardiovascular risk factors. A sample of patients, users of an Integrated Medicine Ambulatory, was analyzed as to age, sex, BMI, waist circumference and clinical conditions such as arterial hypertension, diabetes mellitus type 2, metabolic syndrome (MS), tobacco use and sedentary lifestyle. Patients who already had their waist circumference measured or BMI calculated were selected from the sample, so that 119 patients actually entered the study. Their age mean was 50±13,4 years, 89% were females. The prevalence of obesity and abdominal obesity was 44% and 66% respectively. Both obesity and abdominal obesity were associated with MS (p=0,01, OR=3,42; p=0,0005, OR=7,55) and with each other (p<0,0001, OR=22,1). Circumference measurement was a diagnostic test for MS presenting sensitivity (89.5%) and a good negative prediction value (80%) in our patients. The prevalence of obesity and abdominal obesity was high in this sample. Obesity and abdominal obesity are associated with MS. These data confirm circumference measurement as an important diagnostic tool in the clinical practice.
