Título: Capacidade antioxidante total do plasma e risco cardiometabólico em adultos jovens, não obesos e clinicamente saudáveis Autor(es): Costa, Jamille Oliveira; Vásquez, Cecília M. Passos; Santana, Gleiciane de Jesus; Silva, Natanael de Jesus; Braz, Juciene de Matos; Jesus, Amélia Maria Ribeiro de; Silva, Danielle Góes da; Cunha, Luana Celina Seraphim; Barbosa, Kiriaque Barra Ferreira Abstract: Background: The oxidative biomarkers play an important role in the genesis of cardiometabolic risk-related processes. Objective: To investigate the total antioxidant capacity of plasma and its association with cardiometabolic risk in non‑obese and clinically healthy young adults. Methods: University students of the state of Sergipe, Brazil, aged between 18 and 25 years, were recruited for this study from May of 2013 and October of 2014. Anthropometric, clinical and biochemical parameters were measured and analyzed using protocols which were previously standardized and described in the literature. The measurement of plasma total antioxidant capacity was based on the ability that all the antioxidants present in the sample (plasma) have to inhibit the oxidation of the oxidizable substrate ABTS (2,2`- Azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS•+ by metmyoglobin. Results: Approximately 25% of the sample presented more than one component of cardiometabolic risk. Low HDL‑cholesterol was the most prevalent component. Compared to absence of components, the subjects with at least one component presented greater body weight and waist circumference, higher levels of diastolic blood pressure and fasting glucose, greater total cholesterol/HDL-c ratio, and lower levels of HDL‑c (p < 0.05). Fasting glycemia was the only parameter which was associated with total antioxidant capacity (R2 = 0.10; β = 0.17; p = 0.001). Conclusions: The plasma total antioxidant capacity was not able to predict the cardiometabolic risk components due possibly to the establishment of compensatory mechanisms that become activated in physiological conditions.

Título: Fatores associados ao risco de insegurança alimentar e nutricional em famílias de assentamentos rurais Autor(es): Almeida, Jamylle Araújo; Santos, Amaury Silva; Nascimento, Maria Adriana de Oliveira; Oliveira, José Valter Costa; Silva, Danielle Góes da; Mendes Netto, Raquel Simões Abstract: Food insecurity occurs when the right to food in adequate quality and quantity on a regular basis is disrespected. This study aimed to identify food and nutrition insecurity (FNI) and its possible association with socioeconomic and dietary variables in rural settlements of Sergipe. We verified food insecurity through the Brazilian of Food Insecurity Scale and associations via odds ratio multivariate regression analysis. We evaluated 179 families from four rural settlements in the state of Sergipe. An FNI prevalence of 88.8% was identified (48.6% light insecurity, 25.1% moderate and 15.1% severe). An adjusted statistical association was found between FNI and variables family income per capita (ORa = 3.11, p = 0.008) and food variety (ORa = 2.73, p = 0.004). Families showed high prevalence of food and nutritional insecurity, determined by low income and low variety of food in this population. It is essential to implement more effective and comprehensive public policies that actually ensure food security, also aiming at nutrition education and greater food production opportunities

Título: Inadequações dietéticas em atletas: uma comparação entre homens e mulheres Autor(es): Nascimento, Marcus Vinicius Santos do; Vila-Nova, Tiago Marcel Santos; Silva, Danielle Góes da; Nascimento, Vitor Teixeira; Mendes Netto, Raquel Simões Abstract: The present study aimed to evaluate and compare the dietary intake between male andfemaleathletes.The study included 80high performance athletes, including 43 male and 37 female. The athletes dietary intake was evaluated bya24-hour recall. Both groups showeda low caloric intake. Menwere moreinadequatein protein andsaturated fat intake. Both groups showeda highinadequacy in vitamin A, E, Dand calcium intake.Women had a higherinadequacy invitaminB12, B3, magnesium, folate, phosphorus, and five times more probabilityof inadequate iron intake. Women hada more inadequateintake offruit, meat.Athletesof both sexespresentinadequacieson dietary intake,however, thesewere higheramong women.
