Prevalence of dyslipidemias and food consumption: a population-based study. / Prevalência de dislipidemias e consumo alimentar: um estudo de base populacional.

This study aimed to assess the prevalence of dyslipidemia and its association with an adequate intake of carbohydrates, saturated, monounsaturated, trans, and omega-3 fats among adults living in Viçosa, Minas Gerais, Brazil. This is a cross-sectional study with 884 adults aged 20 to 59 years. Sociodemographic, food intake, anthropometric, and biochemical data were collected. Associations between study variables were investigated by the chi-square test. There was a high prevalence of dyslipidemia in the study population (64.25%), with most individuals having abnormal levels of at least one serum lipid component. Inadequate intakes of saturated, trans, and monounsaturated fats and carbohydrates were predominant. It is noteworthy that omega-3 intake levels were adequate in most individuals. Eutrophic adults showed a higher prevalence of excessive intake of saturated and trans fats. It was found that 38.7% of individuals with low levels of High Density Lipoprotein cholesterol (HDL-c) had an excessive intake of saturated fat. Most individuals with high triglyceride levels or high triglyceride/HDL-c ratios had an insufficient intake of monounsaturated fat. Further studies are needed to evaluate other factors that may influence dietary patterns.

O presente artigo objetivou estimar a prevalência de dislipidemias e sua associação e adequação da ingestão de gorduras saturadas, monoinsaturadas, trans, ômega-3 e carboidratos, em adultos de Viçosa-MG. Trata-se de um estudo transversal com 884 adultos com idades entre 20 e 59 anos. Foram coletados dados sociodemográficos, de consumo alimentar, antropométricos e bioquímicos da população. As associações entre as variáveis foram verificadas utilizando-se o teste qui-quadrado. Verificou-se elevada prevalência de dislipidemias na população (64,25%), com pelo menos um dos lipídeos séricos alterados. Houve predomínio de inadequação na ingestão de gorduras saturadas, trans, monoinsaturadas e carboidratos. Ressalta-se que a ingestão de ômega-3 esteve adequado para a maioria dos indivíduos. Adultos eutróficos apresentaram maiores prevalências de ingestão excessiva de gorduras saturadas e trans. Observou-se que 38,7% dos indivíduos com HDL-c reduzido apresentaram ingestão acima do recomendado de gordura saturada. A maioria dos indivíduos com triglicerídeos e razão TG/HDL-c elevada possuíam ingestão insatisfatória de gordura monoinsaturada. Faz-se necessária a avaliação de outros fatores que podem influenciar o padrão alimentar.

Effects of curcumin supplementation on sport and physical exercise: a systematic review.

Curcumin is the main phenolic compound in turmeric. It has been investigated recently due to its numerous medicinal properties and health benefits. However, few studies assessed the effects of curcumin supplementation on physical activity practice. Therefore, the purpose of this review is to assess the available evidences with human beings about the potential effects of curcumin supplementation on sport and physical exercise. This systematic review was conducted within the period from January to February, 2019, following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. The LILACS, Medline, SciELO and PubMed databases were used for the search, with no publication date limit. The following terms, with the respective Boolean operators, were searched: "curcumin" AND sports; "curcumin" AND exercise; curcumin AND "aerobic exercise"; "curcumin" AND "resistance exercise"; "curcumin" AND "endurance exercise"; "curcumin" AND "strength exercise". Eleven papers were selected for this review. Most of the studies displayed positive effects of the curcumin supplementation for athletes and physical exercise practitioners, and no side effects were reported. Participants supplemented with curcumin displayed reduced inflammation and oxidative stress, decreased pain and muscle damage, superior recovery and muscle performance, better psychological and physiological responses (thermal and cardiovascular) during training and improved gastrointestinal function. Curcumin supplementation appears to be safe and beneficial for sport and physical exercise in human beings. PROSPERO (CRD42019126763).

Predictive capacity of triglyceride-glucose (TyG) index for insulin resistance and cardiometabolic risk in children and adolescents: a systematic review.

Insulin resistance (IR) in childhood plays a key role in the development of metabolic changes in adulthood, therefore, it is important to diagnose it early. We aimed to investigate studies that evaluated the TyG index for prediction of IR risk and other cardiometabolic risk factors, as well as, the proposed cutoff points in childhood and adolescence. This is a systematic review elaborated according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). The search was performed in Lilacs, PubMed and CAPES Journal Portal, using the terms "TyG index OR triglyceride-glucose index OR triglyceride and glucose index AND children OR adolescent*". Eight articles were included in this review. All were cross-sectional studies with individuals aged ≥2 and ≤20 years old, from the United States, Korea, Mexico, Brazil, and Iran. We concluded that the TyG index was positively associated with other IR prediction methods and appears to be advantageous for predicting IR risk and other cardiometabolic risk factors in children and adolescents (review registration: PROSPERO CRD42018100726).

TAG-glucose (TyG) index in childhood: an estimate of cut-off points and the relation to cardiometabolic risk in 4- to 9-year-old children.

OBJECTIVE: To propose cut-off points for the TAG-glucose (TyG) index in Brazilian children and evaluate the link to cardiometabolic risk. DESIGN: A cross-sectional study with children from a municipality in Minas Gerais, Brazil. Anthropometric (weight, height, waist circumference and waist:height ratio), biochemical (lipid and glucose profile) and blood pressure (BP) tests were performed. Using the receiver operating characteristic curve, cut-off points for the TyG index were proposed according to sex using homoeostasis model of assessment - insulin resistance (IR) as the reference method. SETTING: Viçosa, MG, Brazil. PARTICIPANTS: Children aged 4-9 years (n 515). RESULTS: The TyG index cut-off points to identify the risk of IR were 7·9 and 8·1 for boys and girls, respectively. We observed that 48·7 % of the children had an increased TyG index. The increased TyG index was associated with overweight, total body and central fat, increased BP and altered lipid profile. Children with an increased TyG index had a higher accumulation of cardiometabolic risk factors. CONCLUSIONS: According to the cut-off points proposed by the current study, children at risk of IR estimated by the TyG index presented a higher cardiometabolic risk, including isolated risk factors, as to the higher accumulation of these.
