There is a growing evidence that obesity is not only a weight problem, but it is linked to adverse neurocognitive outcomes. Besides obesity, frontal lobe based cognitive deficits in depressed patients are confirmed, and interactions between depression and obesity are known. In our study we investigated the relationship between cognitive functioning, mood and female obesity. Our findings revealed reduced mental flexibility and sustained attention capacity in obesity together with the presence of depressive mood. The mediating role of depression is confirmed. Positive emotion was associated with cognitive functions independently from BMI. Positive affectivity in obesity treatment is discussed.

    • "Regarding vigilance performance, participants responded faster and with fewer lapses in the postintervention session than in the preintervention session. Even though there is not any study that has specifically investigated the effect of a physical activity intervention in the vigilance of a group of obese adults, our results are similar to those reported in a previous study that established a negative association between BMI and the performance in a sustained attention task (Cserj esi et al., 2009; Kim et al., 2007). Similarly, Casado et al. (2013) compared the performance of two groups well differentiated in terms of cardiorespiratory fitness level in three cognitive tasks: the PVT, a temporal orienting task and a perceptual discrimination task.

    ABSTRACT: We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population.

    ABSTRACT: Understanding the drivers for improving Scotland's dietary health is one of the key objectives within the ‘Food, Land and People’ component of the Scottish Government's Strategic Research Programme (SRP). Food producer, processor, retailer and consumer behaviour relative to diet and health are investigated through the programme's ‘Healthy Safe Diets’ theme. The research recognizes both the importance of food to Scotland's economy, health and wellbeing, as well as the challenges faced by the burden of obesity and dietary-related illness. The Healthy Safe Diets theme's analysis of diet and behaviour has a focus on the interplay of the social, biological, behavioural and environmental determinants of nutritional health and aims to develop and test prototype policy interventions relevant to improving the health of Scotland's population. Here, we argue the necessity for concerted and coordinated multidisciplinary approaches to understand and influence dietary behaviour within the changing technological, economic, social and cultural context of individuals within society. The SRP's structure encourages and is developing such interdisciplinary links. Inherent to this is the combining of qualitative and quantitative approaches; using the insights gained from in depth study of small numbers of people, both to provide a better understanding of the results of quantitative analysis and to inform new research questions. Placed in context with the SRP's wider research objectives (such as on physical activity, the role of ‘urban green space’, enhancing the health-beneficial properties of foods and the environmental sustainability of food production and supply), SRP interconnection offers significant opportunity to develop synergies and reconcile conflicts between research areas to create cohesive policy advice and enhance health and wellbeing outcomes.
