ABSTRACT Objective: Dyslipidemia is a common cardiovascular risk factor, with ongoing debate over whether lipid profile assessment, with or without fasting, affects the accuracy of cardiovascular risk evaluation. The objective of this study is to evaluate the effect of fasting status on lipid profile values and the prevalence of dyslipidemia. Subjects and methods: A total of 269 adults (20-69 years) from Vitória-ES (Brazil) were included. Two blood samples were collected on the same day: one in the morning after a […]

ABSTRACT Objective: The aim of the present study was to evaluate the prevalence of total cholesterol (TC) and low-density lipoprotein (LDL) alterations in children and adolescents in Brazil. Materials and methods: A systematic review and meta-analysis of prevalence. The search for articles was carried out in the databases: Medline (PubMed), Embase, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (Lilacs). The meta-analysis was performed using the random effects model. The I² test was used to […]

ABSTRACT Objective: The aim of this study was to carry out an epidemiological analysis of metabolic syndrome among Brazilian Army soldiers. Subjects and methods: Two thousand seven hundred and nineteen male soldiers of the Brazilian Army were evaluated from 2014 to 2016. Characteristics: age = 27.77 (± 8.59) years and BMI = 25.15 (± 3.41) kg/m2. Blood tests and anthropometric measures were performed following the criteria of the International Diabetes Federation Task Force on MS Epidemiology and Prevention, 2009. The […]

Objective The association between type 1 diabetes mellitus (T1D) and dyslipidemia (DLP) increases the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the presence of dyslipidemia in young T1D patients. Materials and methods The study design was cross-sectional and descriptive. We reviewed medical records of T1D patients followed at an endocrinology service, from 1998-2012. Data collected: gender, actual age and age at diagnosis, duration of T1D since diagnosis, body mass index (BMI), pubertal stage, glycemic […]

OBJECTIVE: To identify the prevalence and correlates of dyslipidemia in adults living in the city of Ribeirão Preto, SP, Brazil, in 2007. MATERIALS AND METHODS: A cross-sectional population-based epidemiological study was carried out using a three-stage cluster sampling. The variability introduced in the third sampling fraction was corrected, resulting in a weighted sample of 2,471 participants. Dyslipidemia prevalence, defined as abnormal values in at least one of four lipid fractions was estimated in both genders, according sociodemographic, behavioral, and health-related […]

OBJECTIVE: To evaluate the influence of the interaction between endothelial nitric oxide synthase gene (NOS3) polymorphisms at positions -786T>C, Glu298Asp and intron 4b/a, and cardiorespiratory fitness on plasma nitrite/nitrate levels, blood pressure, lipid profile, and prevalence of cardiometabolic disorders. SUBJECTS AND METHODS: Ninety-two volunteers were genotyped for NOS3 polymorphisms at positions (-786T>C and Glu298Asp) and (intron 4b/a) and divided according to the genotype: non-polymorphic (NP) and polymorphic (P). After that, they were subdivided according to the cardiorespiratory fitness associated with […]

OBJECTIVE: To evaluate insulin resistance and lipid profile in women with congenital adrenal hyperplasia (CAH) caused by classical 21-hydroxylase deficiency (21OHD), and their association with body mass index (BMI) and corticosteroid dosage. SUBJECTS AND METHODS: We assessed BMI, waist circumference, current glucocorticoid dosage, glucose, insulin and lipid profile in eighteen young women (mean ± SD, 19.3 ± 3.0 years) with 21OHD CAH. RESULTS: BMI was normal in 12 patients, 5 of them were overweight, and 1 was obese. Waist circumference […]

Metabolic syndrome (MS) has been a condition involved in considerable controversy, starting with the terminology. Gerald Reaven himself, the author who proposed the term MS, advised against the use of this terminology because the definition implies in at least three metabolic alterations, and it is never clear to which group of alterations we are referring to when we say that a patient has MS. In children, the problem is even more complicated, since there are many different adaptations to the […]

OBJECTIVE: The aim of this study was to assess whether subclinical hypothyroidism (SCH) is associated with carotid atherosclerosis, as well as dyslipidemia, and arterial hypertension. SUBJECTS AND METHODS: The study included 69 consecutive patients with newly diagnosed SCH, and 30 matched healthy controls. Body mass index (BMI), TSH, fT4, antibodies to thyroid peroxidase (TPOabs), lipids, blood pressure, mean and maximum carotid intima-media thickness (CIMT) were determined in all participants. RESULTS: Mean values of CIMT, triglycerides, and total cholesterol/HDL-C ratio were […]

OBJECTIVE: To analyze the cardiovascular risk of non-obese women with polycystic ovary syndrome (PCOS) by the LAP index (lipid accumulation product). SUBJECTS AND METHODS: 283 patients (18-34 years) assigned at the University Hospital of the Federal University of Rio Grande do Norte, Natal-RN, were divided into four groups: 1) lean PCOS (n = 35); 2) healthy lean (n = 162); 3) overweight PCOS (n = 28); 4) healthy overweight (n = 58). RESULTS: Patients with PCOS showed higher values of […]

The World Health Organization (WHO) has recently reinforced the fact that inadequate diets, along with physical inactivity, are among the ten main determinant factors of mortality. Several randomized trials demonstrated that dietary interventions may lower or even prevent the occurrence of several non-communicable diseases. In this context, the role of diet has been exhaustively evaluated in several clinical and epidemiological studies. Thus, it is well established in literature that the amount and type of dietary fat have a direct influence […]

The aim of the present study was to review the possible role of dietary lipids in diabetic nephropathy (DN), taking into account associated abnormalities of serum lipids and interaction of dietary and genetic aspects. Dietary lipids may have an important role in the development and progression of DN. The fat diet composition has been associated with DN, particularly with microalbuminuria, serum lipids abnormalities, and endothelial function. However, the beneficial effect of fat intake modification for these patients is not fully […]
