RESUMEN
FUNDAMENTO: Recentes pesquisas tem se concentrado no uso de biomarcadores inflamatórios na previsão de risco cardiovascular. Entretanto, a informação é escassa em relação à associação entre esses marcadores inflamatórios com outros fatores de risco cardiovasculares em indianos asiáticos, particularmente em mulheres. OBJETIVO: Explorar a associação entre marcadores inflamatórios tais como proteína C-reativa de alta sensibilidade (PCR-as) e contagem de leucócitos (LEU) e fatores de risco cardiovascular tais como adiposidade geral e central, pressão arterial, variáveis lipídicas e lipoproteicas e glicemia de jejum. MÉTODOS: Conduzimos uma análise transversal de 100 mulheres com idade entre 35-80 anos. As participantes foram selecionadas através da metodologia de amostragem por cluster, de 12 distritos urbanos selecionadas ao acaso na Corporação Municipal de Kolkata, Índia. RESULTADOS: A PCR-as apresentou uma associação significante com o índice de massa corporal (IMC) (p < 0,001) e circunferência da cintura (CC) (p = 0,002). Associações significantes inversas foram observadas entre a lipoproteína de alta densidade colesterol (HDL-c) e ambos marcadores inflamatórios PCR-as (p = 0,031) e LEU (p = 0,014). A apo-lipoproteína A1 (Apo A1) também estava negativamente associada com a PCR-as. A contagem de leucócitos apresentou uma correlação significante com a glicemia de jejum e a razão colesterol total (CT) /HDL-C. Usando regressão logística ajustada para idade, IMC (odds ratio/OR, 1,186; intervalo de confiança/IC, 1,046-1,345; p=0,008) e LEU (OR, 1,045; IC, 1,005-1,087; p=0,027) foram as covariantes significantemente associadas com a PCR-as. CONCLUSÃO: No presente estudo, os fatores de risco tais como IMC, CC e HDL-c e Apo-A1 mostraram uma associação significante com PCR-as. A contagem de leucócitos estava significantemente associada com os níveis de HDL-c, glicemia de jejum, razão CT/HDL-c em mulheres.
BACKGROUND: Recent research has focused on the use of inflammatory biomarkers in the prediction of cardiovascular risk. However, information is scant regarding the association between these inflammatory markers with other cardiovascular risk factors in Asian Indians, particularly in women. OBJECTIVE: To explore the association between inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP) and white blood cell (WBC) count and cardiovascular risk factors such as overall and central adiposity, blood pressure, lipid and lipoprotein variables and fasting glucose. METHODS: We conducted a cross-sectional analysis on 100 women aged 35-80 years. Participants were selected following cluster sampling methodology from 12 different randomly selected urban wards of Kolkata Municipal Corporation. RESULTS: Hs-CRP has a significant association with body mass index (BMI) ( p < 0.001) and waist circumference (WC) (p = 0.002). Significant inverse associations were observed between high-density lipoprotein cholesterol (HDL-C) and both inflammatory markers, hs-CRP (p = 0.031) and WBC count, (p = 0.014). Apolipoprotein A1 (Apo A1) was also negatively associated with hs-CRP. WBC count has significant correlation with fasting glucose and total cholesterol (TC) /HDL-C ratio. Using logistic regression, adjusting for age, BMI (odds ratio/OR, 1.186; confidence interval/CI, 1.046-1.345; p=0.008) and WC (OR, 1.045; CI, 1.005-1.087; p=0.027) were the covariates significantly associated with hs-CRP. CONCLUSION: In the present study, risk factors like BMI, WC, and HDL-C and apo A1 show significant association with hs-CRP. WBC count was significantly correlated with HDL-C, fasting glucose, TC/HDL-C ratio in women.

OBJETIVO: Explorar la asociación entre marcadores inflamatorios tales como proteína C-reactiva de alta sensibilidad (PCR-as) y recuento de leucocitos (LEU) y factores de riesgo cardiovascular tales como adiposidad general y central, presión arterial, variables lipídicas y lipoproteicas y glucemia de ayuno. MÉTODOS: Condujimos un análisis transversal de 100 mujeres con edad entre 35-80 años. Las participantes fueron seleccionadas a través de la metodología de muestreo por cluster, de 12 distritos urbanos seleccionadas al azar en la Corporación Municipal de Kolkata, India. RESULTADOS: La PCR-as presentó una asociación significativa con el índice de masa corporal (IMC) (r=0,373, p<0,001) y circunferencia de la cintura (CCI) (r=0,301, p=0,002). Asociaciones significativas inversas fueron observadas entre la lipoproteína de alta densidad colesterol (HDL-c) y ambos marcadores inflamatorios (r= -0,220, p=0,031 y r= -0,247, p=0,014 para PCR-as y LEU, respectivamente). La apo-lipoproteína A1 (Apo A1) también estaba negativamente asociada con la PCR-as (r= -0,237, p=0,031). El recuento de leucocitos presentó una correlación significativa con la glucemia de ayuno (r=0,253, p=0,011) y la razón colesterol total (CT) /HDL-C (r=0,284, p=0,004). Usando regresión logística ajustada para edad, IMC (odds ratio/OR, 1,186; intervalo de confianza/IC, 1,046-1,345; p=0,008) y LEU (OR, 1,045; IC, 1,005-1,087; p=0,027) fueron las covariantes significativamente asociadas con la PCR-as. CONCLUSIÓN: En el presente estudio, los factores de riesgo tales como IMC, CCI y HDL-c y Apo-A1 mostraron una asociación significativa con PCR-as. El recuento de leucocitos estaba significativamente asociado a los niveles de HDL-c, glucemia de ayuno, razón CT/HDL-c en mujeres.
