Influence of nutrient intake on antioxidant capacity, muscle damage and white blood cell count in female soccer players

11 p.Background: Soccer is a form of exercise that induces inflammatory response, as well as an increase in free radicals potentially leading to muscle injury. Balanced nutritional intake provides important antioxidant vitamins, including vitamins A, C and E, which may assist in preventing exercise-related muscle damage. The purpose of the present study was to determine the effect of macro/micronutrient intake on markers of oxidative stress, muscle damage, inflammatory and immune response in female soccer players.-- Methods: Twenty-eight female players belonging to two soccer teams of the same professional soccer club participated in this study after being informed about the aims and procedures and after delivering written consent. Each team completed an 8-day dietary record and played one competition match the same week. Participants were divided into two groups: the REC group (who complied with recommended intakes) and the NO-REC group (who were not compliant). Laboratory blood tests were carried out to determine hematological, electrolytic and hormonal variables, as well as to monitor markers of cell damage and oxidative stress. Blood samples were obtained 24 h before, immediately after and 18 h after official soccer matches. Student t-test or Mann–Whitney U-test was used to compare both groups throughout the match.-- Results: At rest, we observed that the REC group had higher levels of total antioxidant status (TAS), glutathione peroxidase (GPx), and lower levels of creatine kinase (CK) and lactate dehydrogenase (LDH) in comparison to the NO-REC group. Immediately after the match, levels of TAS, GPx, superoxide dismutase (SOD), LDH and % lymphocytes were higher and the % of neutrophils were lower in the REC group compared to the NO-REC group. These differences were also maintained 18 h post-match, only for TAS and GPx.-- Conclusions: Our data reveal an association between nutritional intake and muscle damage, oxidative stress, immunity and inflammation markers. The benefit of the intake of specific nutrients may contribute to preventing the undesirable physiological effects provoked by soccer matches.This study was partially supported by the University of The Basque Country (UPV/EHU), research project EHU09/44

Successful breastfeeding among women with intention to breastfeed: From physiology to socio-cultural factors

[EN] Background: Even if women have intention to breastfeed, they do not always achieve a successful breastfeeding. Aim: This study aims to analyse factors affecting breastfeeding prevalence among mothers that intended to breastfeed. Methods: This is a prospective observational study involving 401 pregnant women that intended to breastfeed (asked at the 20th week). Breastfeeding prevalence was evaluated in reference to health-related, socio-cultural factors and healthcare professionals' interventions at 1 month, 6 months and 12 months after birth. Data were analysed using descriptive statistical methods, bivariate logistic regression and multivariate logistic regression modelling. Results: Independent factors negatively affecting breastfeeding prevalence related to mothers' and newborns' health parameters and birth characteristics included smoking during pregnancy, anaemia and use of analgesia during labour. Regarding sociocultural parameters, being an immigrant, higher education level, intention to breastfeed before pregnancy, comfort with public breastfeeding and bedsharing were positively linked to breastfeeding, while teat or pacifier use in the first week was negatively linked. Regarding healthcare professionals' practices, mother and father/partner antenatal education course attendance and exclusive breastfeeding at the hospital were positively associated with breastfeeding. Conclusion: Breastfeeding is a very complex phenomenon affected by multiple and diverse variables. Physiological factors only affect the short term (1st month), while middle and long term BF affecting variables are mainly identical and include mostly socio-cultural factors and also BF related practices, especially in the first days after birth. These data should help to develop more effective breastfeeding promotion strategies.Funding GGTM has received the grant OSIBB18/024 from BIOEF (Fundacion Vasca de Innovacion e Investigacion Sanitarias) .

Patterns of Change in Dietary Habits and Physical Activity during Lockdown in Spain Due to the COVID-19 Pandemic

Background: Lockdown due to COVID-19 influenced food habits and lifestyles with potential negative health impact. This study aims to identify patterns of change in eating habits and physical activity during COVID-19 lockdown in Spain and to identify associations with sociodemographic factors and usual habits. Methods: This cross-sectional study included 1155 adults recruited online to answer a 10-section questionnaire. The protocol assessed usual diet by means of a semi-quantitative food frequency questionnaire, usual physical activity (PA) and supplement use, dietary changes, sedentary time, PA, exposure to sunlight, sleep quality, and smoking during confinement. Patterns of dietary change were identified by factor analysis. Factor scores were included in cluster analysis together with change in PA. Results: Six patterns of dietary change were identified that together with PA changes during lockdown defined three clusters of lifestyle change: a cluster less active, a more active cluster, and a third cluster as active as usual. People who were usually less active were more likely to be classified in the cluster that increased physical activity in confinement. Scores of the Healthy Mediterranean-Style dietary pattern were higher in this group. Conclusions: Different patterns of change in lifestyles in confinement suggest the need to tailor support and advice to different population groups.This research received no external funding. J.A.T. was funded by Instituto de Salud Carlos III through the Fondo de Investigacion para la Salud (CIBEROBN CB12/03/30038) which was co-funded by the European Regional Development Fund

Adaptive response in the antioxidant defence system in the course and outcome in first-episode schizophrenia patients: A 12-months follow-up study

[EN] Correlation of plasma antioxidant enzyme activity with the course and outcome in first-episode schizophrenia patients (n=49) was analyzed in order to assess the possible utility of peripheral markers of oxidative stress as prognostic factors. These markers were measured shortly after the onset of schizophrenia, and again 1, 6 and 12 months later. A decrease in catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and glutathione (GSH) levels and total antioxidant status (TAS), as well as an increase in thiobarbituric acid reactive substances (TBARS), were observed 1 month after (p<0.05). 6-Months later, there was a reduction in TAS, GSH, SOD and GPx, and a increase in TBARS (p<0.05), with a normalization of CAT levels, indicating a persistent alteration of the antioxidant system and the maintenance of oxidative stress. At 12-months, a considerable decrease was observed in TBARS. Additionally, while the level of GPx decreased (p<0.05) further, SOD and GSH levels and TAS were normalizing, indicating a partial regeneration of the antioxidant defence system. These results indicate the possible contribution of oxidative stress to the onset and pathophysiology of schizophrenia, suggesting the involvement of an adaptive response in the antioxidant defence system in the course and outcome in first-episode schizophrenia patients
