RESUMEN

Menopause is associated with an increased body weight and changes in fat distribution, high levels of homocysteine and cardiovascular risk factors associated with estrogen deficiency. The objective was to evaluate body mass index (BMI), waist circumference (WC), waist/hip index (WHI), and serum homocysteine (Hct) levels in postmenopausal women (n 128). Nutritional status was diagnosed by BMI (WHO), WC (normal <88cm, at risk> 88cm), WHI (normal <0.8, at risk> 0.8), serum homocysteine (Hct) (ELISA) normal < 10 mmol/L, at risk >10-15mmol/L, high >15mmol/L and estradiol (ELISA) <65pg/mL (menopause). Sixty five point nine percent were overweight/obese, 47.3 percent and 82.2 percent showed cardio metabolic risk by WC and WHI. There was a significant difference for WHI, and a positive significant correlation between anthropometrics indexes. Ten percent showed risk and hyperhomocysteinaemia, but it was not correlated with the evaluated variables. The subjects had a high frequency of overweight, obesity and android fat distribution, showing a high risk for cardiometabolics diseases.


La menopausia se asocia a un aumento del peso corporal y a cambios en la distribución de grasa, describiéndose también niveles elevados de homocisteína, factores de riesgo cardiovascular asociados al déficit de estrógenos. El objetivo de este estudio fue evaluar índice de masa corporal (IMC), la circunferencia de cintura (CCi), el índice cintura-cadera (ICC), la homocisteína sérica en mujeres posmenopáusicas (n: 128). El diagnóstico nutricional antropométrico se determinó según IMC (OMS); se determinaron la CCi (normal <88cm, en riesgo >88cm), ICC (normal <0,8, en riesgo >0,8), homocisteína sérica (tHci) (ELISA): normal < 10mmol/L, en riesgo >10-15mmol/L, alta: >15mmol/L y estradiol (ELISA): <65pg/mL (posmenopausia). 65,9 por ciento presentaron sobrepeso/ obesidad. 47,3 por ciento y 82,2 por ciento en riesgo cardiometabólico según CCi e ICC. Hubo diferencia significativa para ICC y correlación positiva significativa entre indicadores antropométricos. 10 por ciento presentó riesgo e hiperhomocisteinemia. Este aminoácido no correlacionó con las variables evaluadas. Las mujeres evaluadas presentaron una alta frecuencia de sobrepeso-obesidad y una distribución de grasa tipo androide, presentando un alto riesgo para enfermedades cardiometabólicas.

RESUMEN

En el envejecimiento se observa tendencia a hiperlipidemias, cambios en la distribución de lipoproteínas y una declinación del sistema de defensa antioxidante del organismo. El objetivo de este estudio fue relacionar concentraciones séricas de colesterol total, fracciones, triglicéridos y Vitaminas C y E. Se evaluaron 61 adultos mayores de 60 años de edad, de enero-marzo, 2006. Se diagnosticó estado nutricional por IMC; se determinaron niveles séricos de triglicéridos (TG), colesterol total (CT) y fracciones (HDL-c y LDL-c), (método enzimático), Vitamina C (método colorimétrico) y Vitamina E (HPLC). Se utilizaron valores de ATPIII como referencia para riesgo de TG, CT, HDL, LDL-c; vitamina C: > 0,9 mg/dL (normal), < 0,9mg/dL (déficit); vitamina E: >1300 µg/dL (normal), =1300 µg/dL (déficit). Se calculó consumo dietario de vitaminas C y E por método de pesada directa tres días/semana. Según IMC, 19,7 por ciento presentó déficit nutricional, 39,3 por ciento sobrepeso y 11,5 por ciento obesidad. TG, CT, LDL-c en riesgo para el sexo femenino y HDL-c para ambos sexos. La prevalencia de riesgo para enfermedades cardiovasculares fue: TG (45,2 por ciento), HDL-c (51,1 por ciento), LDL-c (52,5 por ciento), deficientes de vitamina C (9,8 por ciento) y E (90,2 por ciento). El consumo y niveles séricos de vitamina E en déficit en ambos sexos. No hubo asociación entre las variables. Correlación significativa y positiva entre TG, CT, LDL-c, vitamina E sérica e IMC. El grupo femenino presentó sobrepeso, hipertrigliceridemia e hipercolesterolemia, HDL-c y LDL-c en riesgo y el grupo total estado de vitamina E deficiente, importantes factores de riesgo para enfermedad cardiovascular en este grupo etario.


During aging there is a tendency towards hyperlipidemia and changes in the distribution of lipoproteins. A decline in the functioning of the body’s antioxidant defense system is also observed at this time. The objective of this study was to establish the relationship between serum concentrations of total cholesterol and fractions, triglycerides, and Vitamins C and E. 61 adults over 60 years of age were evaluated from January to March, 2006. Nutritional status was diagnosed by BMI (WHO); serum levels of triglycerides (TG), total cholesterol (TC) and fractions (HDL-c and LDL-c) were determined by enzyme method; Vitamin C (colorimetric method) and Vitamin E by HPLC. ATPIII values were used as a reference for risk of TG, TC, HDL, LDL-c, vitamin C:> 0.9 mg/dL (normal), <0.9 mg/dL (deficit); vitamin E: =1300 µg/dL (normal), 1300 = µg /dL (deficit). Consumption of vitamins C and E were estimated by the direct weighing method 3 days per week. According to BMI, 19.7 percent had nutritional deficit, 39.3 percent overweight, and 11.5 percent obesity. TG, TC, LDL-c levels were at risk in females, and HDL-c in both genders. Prevalence of risk for heart disease was: TG (45.2 percent), HDL-c (51.1 percent), and LDL-c (52.5 percent). Consumption and serum levels of vitamin E were low in both genders. There was no association between variables. A significant and positive correlation between TG, TC, LDL-C, serum vitamin E, and BMI was observed. The female group showed overweight, hypertriglyceridemia and hypercholesterolemia, HDL-c and LDL-c at risk, and vitamin E deficiency, all of which are important risk factors for cardiovascular disease in this age group.

RESUMEN

The anatomical and physiological changes of aging make elderly people a vulnerable group to malnutrition and specific deficiencies of nutrients such as vitamin B12 and folate. This study was aimed to establish relationships among serum vitamin B12, folate, homocysteine concentrations and dietary intake and adequacy. Fifty five male and female elderly (60 and more years), free-living, were assessed. Measurements were: serum vitamin B12 and folate by radioimmunoanalysis (RIA), homocysteine by polarized fluorescence immunoassay, nutrient intake by three 24 hours recalls and food frequency questionnaire. Nutritional status was determined by Body Mass Index (BMI). Serum vitamin B12 and folate were at normal range (423,3+/-227,6 pmol/l and 6,4 +/- 4,5 mg/ml), but 17,5% of elderly had B12 deficiency and 12% had folate deficiency. Serum homocysteine was higher than reference values (15,8+/-4,4 mmol/l), but 47,5% showed concentrations above 15 mmol/L, male population showed higher mean value (p: 0,01). Nutrient intake was inadequate by deficiency. BMI indicated 11,8% of undernutrition, 29,4% of overweight and 20,6% of obesity A negative and inverse correlation between homocysteine and serum folate was found. Results suggest a biochemical deficiency of B12 and folate that is expressed as elevated homocysteine levels. These finding represent a high cardiovascular risk factor for this elderly group.
