Estudio Retrospectivo y Comparativo para Analizar el Porcentaje de Incremento del Colesterol Total, HDL, LDL y triglicéridos Respecto al Índice de Masa Corporal

Abstract

Study Title: A retrospective, comparative analysis of the percentage increase in total cholesterol, HDL, LDL and triglycerides compared to body mass index. Type of intervention: Observacional Type of analysis: Comparative Temporality Retrospective Method of observation: Longitudinal Design Type: Cases and controls Number of patients 50 Hypothesis: • Primary: Overweight patients had levels of total cholesterol, HDL, LDL and triglycerides higher than obese patients. • Secondary: By reducing body mass index (BMI) through a low calorie diet plasma levels of total cholesterol, HDL, LDL andtriglycerides tend to decrease. Primary objective: To determine whether the change from baseline in the variablestotal cholesterol, HDL, LDL and triglycerides compared to BMI isstatistically si gnificant after nutritional control. Secondary objectives: • Compare the change from baseline in weight after 9 months. • Comparing the change from baseline in total cholesterol, HDL, LDL 8 and triglycerides after 9 months of nutritional control • Compare the change from baseline in BMI achieved after 9 months of the study. Standards for subjects: Men and women ≥ 18 years, overweight or obese, caloriecontrolled diet adjusted according to the requirements of eachpatient, during a period of 9 months and went to their control visits(3, 6 and 9 months) . Main Exclusion Criteria: None. Statistical Considerations: For the evaluation of the primary hypothesis used the t test for two samples assuming unequal variances. On the other hand for secondary hypothesis was conductedbased on a model of analysis of variance (ANOVA).
