Objective: to analyze the impact of the substitution of a rich diet in saturated fats with a rich diet in monounsaturated fats on anthropometric, metabolic and lipid profile in postmenopausal women. Material and methods: a prospective, longitudinal and comparative study where 18 postmenopausal women participated in two periods of dietary intervention of 28 days each one: 1) (SAT diet) consumed butter. Caloric formula (CF) = 15% protein, 38% fat. [20% saturated fat (SFA), 12% monounsaturated fat (MUFA) and 47% carbohydrates and 6% polyunsaturated (PUFA)]. b) Period MONO: with extra virgin olive oil (EVOO). CF = 15% protein, 38% fat (<10% SFA, 22% PUFA and 6% MUFA) and 47% carbohydrates. Size and body composition, glucose, insulin, HOMA, TC, HDL-C, LDL-C, VLDL-C, TG, TC/HDL-C, LDL-C/HDL-C, TG/HDL-C and non-HDL-C/HDL.C were measured; dietary Anamnesis/ 24 hours, daily food record. ANOVA and Bonferroni statistical analysis (SPSS 20) was applied. Results: the age was 56 ± 5 years, BMI 29.8 ± 3.1 kg/m2, waist circumference: 93.2 ± 10.1 cm, waist/hip ratio: 0.86 ± 0.14, waist/height: 0.59 ± 0.06 and 38.6 ± 4% body fat (NS). Lipid profile: SAT diet increased TC (p <0.001), LDL-C (p <0.002) and non HDL-Cholesterol (p <0.000), HDL-C increased in MONO diet (p <0.000). SAT diet: TC/HDL-c ratio, Non col HDL-c/HDL-c, LDL-c/HDL-c (p <0.000) and TG/HDL-c (p <0.000). In MONO diet decreased TC/HDL-c (p <0.015) and TG/HDL-c (p <0.016). Conclusions: the SAT diet increased cardiovascular risk, while the MONO diet decreased the risk to develop the metabolic syndrome components and choronary heart disease. © 2015, Nutr Hosp.

The excess of visceral fat constitutes important predictor of metabolic and cardiovascular risk in children and adolescents, and the waist circumference (WC) is the best anthropometric variable to estimate it. The objective was to estimate the specific WC percentiles by age and gender for children and adolescents, using data obtained from Maracaibo Municipality of Zulia State, Venezuela. For this purpose, a sample of 1787 children and adolescents (884 boys and 903 girls) from 2 until 18 years old, were selected by conglomerate random sampling. A complete physical examination and anthropometric evaluation was performed to each patient to confirm their healthy state. Construction of the smoothed centile curves was performed using the LMS method. Mean WC increased with age, with the values being similar between males and females until 8 years old, after which values are slightly higher in males. For both genders, the values of WC in each percentile increased with the age. Compared with other countries, our values of WC in percentile 50 for both groups were similar, but slightly superior to the values registered by Colombia, Canada, USA, Hong Kong and London until age 9, after this age a constant increase in average of 2.5 cm from one year to another was observed. Both gender curves approach the USA curves. Nevertheless, an increase in the values of WC in the male group from the 10 years was observed, compared with the other countries, even USA. These first estimations of percentiles of WC and their corresponding curves for children and adolescents from Maracaibo Municipality, will allow to identify subjects with abdominal obesity (after cut-off points are established in future investigations) and thus to define not only the strategies for attention, but also for prevention cardiovascular and metabolic risk in this vulnerable group.
