Background and Objectives: Overweight and obesity are growing public health challenges, particularly concerning young adults. University life presents a unique set of stressors that may influence weight management alongside sleep quality. In this cross-sectional study, we aimed to investigate the association between overweight or obesity, stress, and sleep quality in a large sample of Greek university students. Materials and Methods: The study recruited 2116 active students from across various Greek universities. Participants completed questionnaires on sociodemographics, academic performance, and physical activity levels using the International Physical Activity Questionnaire (IPAQ). Stress and sleep quality were assessed using the Perceived Stress Scale (PSS) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Body weight and height were directly measured to calculate Body Mass Index (BMI). Results: Our analysis of 2116 Greek university students revealed significant associations between various factors and overweight/obesity. Compared to their rural counterparts, young adults in urban areas had an 88% higher prevalence of overweight/obesity (p = 0.0056). Regular smokers were twice as likely to be overweight or obese (p = 0.0012). Notably, those with low physical activity levels displayed a more than two-fold increased risk (p = 0.0008) compared to those with moderate or high activity levels. Similarly, students with moderate or high perceived stress levels had a more than two-fold prevalence of overweight/obesity compared to those with low stress (p = 0.0005). Inadequate sleep quality was also associated with an 86% higher risk of overweight/obesity (p = 0.0007). Interestingly, good academic performance showed a 57% greater prevalence of overweight/obesity compared to very good/excellent performance (p = 0.0103). Conclusions: Our findings reveal that perceived stress and poor sleep quality are significant risk factors for overweight and obesity in this young adult population.

Background: Mediterranean diet (MD) constitutes a commonly examined dietary model. It includes a plethora of bioactive ingredients with strong antioxidant, anti-inflammatory, antithrombotic and anticancer properties. Several substantial studies support strong evidence that MD can exert preventing actions against human morbidity and mortality, promoting human well-being and quality of life. The present study aims to evaluate whether childhood MD compliance may be associated with socio-demographic, anthropometric, and lifestyle factors in children at the age of 6–9 years. Methods: This is a cross-sectional survey on 3875 children aged 6–9 years old with their matched mothers. Qualified questionnaires were used to evaluate and collect by one-to-one interviews with trained professionals the above data. Results: Elevated MD adherence was observed only in 22.2% of the enrolled children, while 37.5% of children maintained intermediate MD adherence and 40.3% of children adopted lower MD levels. Children MD compliance was related at an independent manner with maternal education level, childhood anthropometric factors such as Body Mass Index (BMI), Waist circumference to Height ratio (WtHR), quality of life, and exclusively breastfeeding behaviors after adjusting for several possible confounders (p ˂ 0.05). Conclusions: Elevated MD adherence of children aged 6–9 years old showed a lower obesity of overweight/obesity, including abdominal obesity. A higher maternal educational status and adopting exclusively breastfeeding practices were associated with greater levels of children’s MD adherence, promoting their quality of life and well-being. Based on the present results, future prospective surveys need to be performed to evaluate if there is a causality relation concerning this topic.

Background/Objectives: The number of children with overweight and obesity is gradually increasing worldwide. This is an emergent public health problem as overweight and obesity persist through the next stages of human life, being associated with high risk of morbidity and mortality. In this respect, the purpose of the current cross-sectional survey is to explore whether the overweight/obesity of children aged 6–9 years may be related to the risk of developing perceived stress and poor sleep quality symptoms. Methods: This study recruited 4350 primary school children from diverse Greek rural and urban regions. The mothers of the enrolled children completed relevant questionnaires on children and maternal sociodemographics, anthropometric parameters, perinatal outcomes, breastfeeding practices, and lifestyle factors. The enrolled mothers also completed the Perceived Stress Scale (PSS) and the Pittsburgh Sleep Quality Index (PSQI) to evaluate the perceived stress and sleep quality of their matched children, respectively. Results: Our analysis reveals independently significant associations between diverse factors and children’s overweight/obesity such as child’s gender, family economic status, maternal gestational weight gain, childbirth weight, kind of delivery, exclusive breastfeeding, and children physical activity. Childhood overweight and obesity were independently associated with a more than three-fold higher risk of perceived stress and a more than two-fold higher likelihood of poor sleep quality after adjustment for multiple confounding factors. Conclusions: Obesity and overweight are related to enhanced risk of perceived stress and poor sleep quality in children aged 6–9 years. Public policies and dietary counseling interventions should be applied to inform new mothers about the harmful effects of childhood overweight/obesity and to direct them to adopt healthy dietary practices for their children.
