SummaryStudy aim: The purpose of this study was to compare intake of antioxidant vitamins (A, C, E) in young women with various levels of physical activity.Material and methods: The study included 3 groups of females: 40 women with no extra physical activity (Sedentary), 40 women involved in regular, moderate sports activities (Recreationally Active) and 40 female athletes competing at an international level (Athletes). Participants’ diet was assessed on the basis of 3-day diet records which were analysed using the computer program ‘Dieta 5.0’. Body composition was evaluated by the bioelectrical impedance analysis (BIA) method.Results: Athletes were characterized by the lowest body fat and highest lean body mass in comparison with the other groups. They also showed the highest intake of energy, proteins and carbohydrates compared to Active and Sedentary women. The consumption of vitamin A amounted to 180.0% of RDA in Athletes, 98.8% in Recreationally Active and 97.8% in Sedentary women. Vitamin C intake in Athletes equalled 275.0% of RDA, whereas the deficiency of this vitamin was observed in Recreationally Active and Sedentary women (62.3% and 46.1% of RDA, respectively). The study groups showed consumption of vitamin E at the level of 146.7% of AI in Athletes, 115.0% in Recreationally Active and 111.3% in Sedentary women.Conclusion: Athletes consumed excessive amounts of antioxidant vitamins. Recreationally Active and Sedentary women met the demand for vitamin A and E, but the intake of vitamin C was not sufficient, which could lead to health problems. The current findings also indicate that energy intake was at a low level regardless of the study group.

In recent decades, interest in the study of the content of fat-soluble antioxidant vitamins among residents of the northern territories of Russia has not weakened, which is associated with the transformation of the diet in a harsh climate, a negative ecological situation resulting from the technogenic pollution of the biosphere with various toxicants, and urbanization of the environment. In recent decades, interest in the study of fat-soluble antioxidant vitamins among residents of the northern territories of Russia has not weakened, which is due to the transformation of the diet in a harsh climate, a negative environmental situation that arose as a result of technogenic pollution of the biosphere with various toxicants. Аim. Conduct a comparative analysis of the content vitamins A, D, E in indigenous and alien populations, living on the territory of the Yamalo-Nenets Autonomous Okrug. Material and methods. The study involved 185 males of working age (31.3 ± 12.2 years), permanently residing in the territory of the Yamalo-Nenets Autonomous Okrug. The study participants were divided into 2 groups: the control group (97 representatives of the newcomer population) and the main group (88 people from the ethnic population: Nenets, Khanty). In all examined individuals, vitamins A and E were determined in the blood by the fluorometric method, and the concentration of hydroxyvitamin D – 25 (OH) D3 was determined using the chemiluminescent method. Results. In the course of a comparative analysis of the content of the studied vitamins in the blood, it was found that the average values of vitamin A in the newcomer population were in the range of optimal values, while the provision with vitamins D and E was 1.4 and 1.1 times lower than the minimum. permissible physiological values, respectively. The opposite picture was observed in the aboriginal population, who had a pronounced deficiency of only vitamin A. Conclusion. The results obtained indicate the presence of intergroup features in the content of fat-soluble vitamins in the body of the population of the Far North, which requires a corresponding correction of the diet and the development of a set of preventive measures aimed at improving the ecology of the environment.

The Impact

Introduction: Acute respiratory infection is a major cause of death for under-5 children in Bangladesh. We aimed to analyze the effect of immunonutritional status, healthcare factors, and lifestyle on the incidence of acute respiratory infection among under-5 children taking individual-level and contextual-level risk factors into consideration. Methods: This study recruited 200 children suffering from acute respiratory infection and 100 healthy controls matched by age, sex, and sociodemographic profile. Serum antioxidant vitamin A (retinol), vitamin C (ascorbic acid), and vitamin E (α-tocopherol) were assessed along with the impact of vaccination, socioeconomic factors, and Z-score on the incidence of acute respiratory infection. Results: Serum antioxidant vitamins were significantly lower in the acute respiratory infection children compared to the non–acute respiratory infection group. Vitamin A was found to be significantly high in acute respiratory infection children who were breastfed for more than 1 year. Vitamin E levels were found to be significantly higher in the acute respiratory infection children who were immunized. Compared to the children living in tin-shed house or huts, serum vitamin E level increased in those acute respiratory infection children who resided in apartments. Vitamin A level was significantly high in those acute respiratory infection children whose height-for-age was −2 SD and above ( Z-score), and vitamin C levels were also significantly high in those acute respiratory infection children whose weight-for-height was −2 SD and below ( Z-score). Conclusion: Deficiencies of antioxidant vitamins along with healthcare and lifestyle factors have a significant influence on the incidence of acute respiratory infection among under-5 children in Bangladesh.

The increasing interest in the possible role of antioxidant vitamins in many disease states means that methods of assessing vitamin intakes which are suitable for large-scale investigations are now required. The suitability of the food-frequency questionnaire, which was developed by the Medical Research Council – Cardiff Group, for determining dietary intake of antioxidant vitamins in epidemiological studies was investigated in 196 Scottish men. The validity of the dietary data was assessed by comparison with serum vitamin concentrations, and separate analyses were performed for current smokers and non-smokers. The results showed that total energy intake and the percentage of energy derived from sugar were higher in smokers, and that both dietary and serum values of vitamin C, β-carotene and vitamin E were lower in smokers than non-smokers. After adjustment for serum lipids, energy intake and body mass index, correlation coefficients between dietary and serum vitamins C and E were similar for smokers (r 0.555 and 0.25 respectively) and non-smokers (r 0.58 and 0.32 respectively). Correlation between dietary and serum carotenes was reduced from 0.28 in non-smokers to 0.09 in smokers and correlations for retinol and total vitamin A were weakly significant only for non-smokers. The food-frequency questionnaire assigned > 70% of subjects correctly into the upper or lower plus adjacent tertiles of serum vitamin values, with the exception of β-carotene and total vitamin A for smokers. Thus, the food-frequency questionnaire appeared to be an adequate tool for assigning individuals into tertiles of serum antioxidant vitamins with the main exception of β-carotene for smokers. Marked differences do occur between the vitamins and between the smoking groups which may reflect reduced accuracy of reporting on the food-frequency questionnaire or differential absorption and metabolism of the vitamins.

OBJETIVO: Apresentar uma análise crítica de estudos da literatura sobre a deficiência de vitamina A (DVA) no Brasil, segundo o indicador bioquímico retinol sérico, considerando-se o impacto negativo da DVA na saúde reprodutiva e no desenvolvimento infantil. FONTES DE DADOS: os bancos de dados Medline e BVS, no período de 1994 a 2007, foram rastreados com a combinação de descritores: "vitamin A deficiency", "Brazil", "pregnant", "children" e "retinol serum level". A inclusão dos artigos foi realizada com base em critérios de elegibilidade referentes à população, desenho do estudo e idioma, enfatizando-se estudos com gestantes, puérperas, nutrizes, lactentes e pré-escolares que não apresentassem doenças crônicas não-transmissíveis ou infecciosas. SÍNTESE DOS DADOS: dos 27 artigos selecionados, 25 eram estudos transversais, um era caso-controle e um estudo longitudinal. Identificou-se que 71% e 25% dos trabalhos com gestantes e crianças, respectivamente, adotaram valores de retinol sérico <1,05µmol/L como ponto de corte. Todos os estudos apontaram a DVA como um problema de proporção preocupante. Reconhece-se a emergente inserção dos adolescentes no grupo de risco potencial para DVA e da antropometria como variável independente para tal deficiência nutricional. CONCLUSÕES: Aponta-se uma necessidade de incluir estratégias de intervenção adicionais à suplementação, reavaliar pontos de corte na interpretação do diagnóstico da DVA e refletir sobre a pertinência da inclusão de novas áreas e grupos com risco potencial para DVA em programas de intervenção.
