PRODUTO DA ACUMULAÇÃO LIPÍDICA NA DETECÇÃO DE FATORES DE RISCO PARA DOENÇAS CARDIOVASCULARES EM MULHERES COM SÍNDROME DOS OVÁRIOS POLICÍSTICOS

Abstract

The polycystic ovary syndrome (PCOS) is considered the most common endocrine disease during the woman's reproductive life, with prevalence ranging from 5 to 10% of women of reproductive age and is characterized by chronic anovulation and hyperandrogenism, showing complex multifactorial pathogenesis. Objective: To determine the cutoff the lipid accumulation product in women with polycystic ovary syndrome. Methods: Cross-sectional study with 78 women between 18 and 42 years diagnosed with polycystic ovary syndrome according to the Rotterdam criteria directed to nutritional evaluation at the Maternal and Child Unit of the University Hospital UFMA. The interest variables were recorded in protocol form: socio-demographic, behavioral, gynecological history, personal and family history of diseases, anthropometric data (weight, height, body mass index and waist circumference), laboratory tests, imaging exams and blood pressure values. The product of lipid accumulation was calculated by the formula described by Kahn. Regarding the analysis of data normality of quantitative variables was analyzed by the Shapiro Wilk; to compare the means of the variables we used the t Student test. To check the correlation between the lipid product accumulation and cardiovascular risk markers was applied Linear Correlation coefficient (r) test. The lipid product accumulation was analyzed according to the Receiver Operating Characteristic Curve, being discriminated values of high sensitivity and specificity simultaneously. The significance level for all tests was 5%. Results: Using the Receiver Operating Characteristic curve to determine the best cutoff of predicted LAP index risk for cardiovascular disease, it was noted that the value above 39.32 cm.mmol/L representing the area under the 0.8845 of the curve. Every women who had lipid product accumulation product value above the cutoff defined also showed the highest changes in mean of risk markers analyzed of cardiovascular diseases, a statistically significant difference. Regarding the analysis of correlation between the product of lipid accumulation above the cutoff defined and risk markers for cardiovascular diseases, there was a significant correlation. Conclusion: These results demonstrate that cutoff values ≥ 39.32 cm.mmol/L of LAP index seems to indicate the increased risk for CVD and should be used as a screening tool and research for its ease of measurement and interpretation, as well as its low cost and may even have its applicability in primary health care.
