[Obesity and anthropometric indicators in a sample of males with Acute Coronary Syndrome in a health area with inclusion of inmates: case-control study]. / Obesidad e indicadores antropométricos en una muestra de varones con Síndrome Coronario Agudo, en un Área de Salud que incluye reclusos: estudio caso-control.

OBJECTIVES: Obesity is a cardiovascular risk factor with a high epidemic burden on ischemic heart disease. The aim of this study was to analyze the anthropometric indicators of obesity in a sample of males who have had an Acute Coronary Syndrome (ACS) diagnosed in a prison referral hospital, and a control group. MATERIAL AND METHODS: Cross-sectional case-control study in a Health Area with inclusion of a penitentiary center. The participants in this study were 204 males, 102 cases and one control selected for each case (n=102). We measured weight, height waist circumference (WC), umbilical waist (UW) and hip circumference. We calculated body mass index (BMI) and other anthropometric indicators: waist to-hip-ratios (WHR and UWHR), waist to-height-ratios (WHtR and UWHtR). We obtained the areas under the receiver operating characteristic curves (AUC), the odds ratio (OR) and the correlations in the infarcted people. RESULTS: Obesity was more prevalent in ACS (31.4% vs 9.1%; OR: 4.7). Other indicators show a discriminatory association. BMI (AUC: 0.699; OR: 3.9), WC (AUC: 0.750; OR: 6.3), UW (AUC: 0.777; OR: 10), inverse height (AUC: 0.619; OR: 2.1), WHR (AUC: 0.832; OR: 11.6); UWHR (AUC: 0.857; OR: 15.6), UWHtR (AUC: 0.800; OR: 8.9). In ACS the correlations for both WC and UW with waist to-height-ratios (WHtR and UWHtR) were strong (all r ≥0.90; p < 0.001). DISCUSSION: The anthropometric indicators of obesity are clearly associated with ACS. UW is the simple measurement with the best association. BMI is most weakly associated. UWHtR presents high discriminatory power and the best anthropometric correlation of risk that supports its use for the identification of males at risk of myocardial infarction in the general population and prison.

Objetivos: la obesidad es un factor de riesgo cardiovascular con alta prevalencia, y relacionado con la cardiopatia isquemica. El objetivo fue analizar mediante antropometria, una muestra de varones con Sindrome Coronario Agudo (SCA) diagnosticado en un hospital de referencia penitenciaria, y un grupo control. Material y metodo: estudio caso-control en un Area de Salud que integraba a un Centro Penitenciario. Los participantes fueron 204 varones, 102 infartados y un control por cada caso. Se midio peso, talla, cintura minima (CC), cintura umbilical (CU) y cadera. Se calcularon el IMC y otros indicadores. Se realizo un analisis descriptivo y se obtuvieron las areas bajo la curva (ABC) greceiver operating characteristich, las odds ratio (OR), y las correlaciones en SCA. Resultados: la obesidad presento mayor prevalencia en SCA (31,4% vs 9,1%; OR: 4,7), otros indicadores mostraron asociacion discriminatoria: IMC (ABC: 0,699; OR: 3,9), CC (ABC: 0,750; OR: 6,3), CU (ABC: 0,777; OR: 10), talla inversa (ABC: 0,619; OR: 2,1), indice cintura/cadera (ABC: 0,832; OR: 11,6); indice CU/cadera (ABC: 0,857; OR: 15,6), indice CU/talla (ABC: 0,800; OR: 8,9). Las correlaciones entre las cinturas y los indices cintura-talla fueron fuertes (todas r .0,90; p <0,001). Discusion: los indicadores antropometricos de obesidad estan asociados al SCA. La CU es la medida simple mas asociada. El IMC presenta una asociacion debil; el indice CU/talla presenta alto poder discriminatorio y la mejor correlacion antropometrica de riesgo, apoyando su uso en la identificacion de varones con riesgo de infarto de miocardio tanto en la poblacion general como penitenciaria (AU)
