The prevalence of childhood obesity in Greece is the highest ever reported together with low adherence rates to the dietary patterns of the MD. Current findings suggest an increased risk for even higher rates of obesity in adolescence and adulthood in the near future. Taking into account that children are also abandoning the traditional cardio-protective MD, the increased risk for future adverse health consequences seems evident.

To investigate whether aquatic athletes follow optimal dietary intake, 58 athletes, all members of the Greek national swimming and water polo teams, were tested. Dietary intake was assessed at the nutrient, food, and food group level using the 24-h recall method and a food frequency questionnaire. Mean energy intake for males and females was 14.3 and 8.5 MJ, respectively. Mean carbohydrate consumption for male and female athletes was 4.5 g/kg and 3.8 g/kg of body weight, respectively. Fat intake was 153 g for males and 79 g for females. A significant number of the athletes (71% of the males, 93% of the females) did not meet the Dietary Reference Intakes for at least one of the antioxidant vitamins. The data suggest that athletes of both genders consumed too much fat and too little carbohydrate. Insufficient fruit and vegetable intake was related to low intake of antioxidants.

These findings could guide future investigations or public health initiatives to prevent and confront the childhood OB epidemic more efficiently.

Objective: Given the rapid increase in the prevalence of childhood obesity, identifying the sociodemographic influences on obesity status is important for planning and implementing effective prevention initiatives. However, this type of data is limited for Greek children. Therefore the aim of the present study was to identify possible sociodemographic factors associated with childhood obesity at the national level. Design: Cross-sectional, population-based survey, carried out from October to May 2009. Setting: Under the context of the GRECO (Greek Childhood Obesity) study, a nationwide sample of 2315 primary-school children. Subjects: Children aged 10-12 years and their parents were voluntarily enrolled. Direct anthropometric measurements of the children were obtained and information on sociodemographic characteristics of the parents, as well as their self-reported values of body weight and height, were collected. Results: Overweight and obesity prevalence was 29?5 % and 13?1 %, respectively, among boys; 29?5 % and 9?0 %, respectively, among girls. Multiple logistic regression analysis revealed that the most important sociodemographic predictors of childhood obesity were mother's age, parental BMI classification and father's type of occupation. More specifically, increased mother's age and normal BMI status of the parents seemed to have a protective effect on the likelihood of having an overweight/obese child. Additionally, the odds of a female child of being overweight/obese were reduced when the father's type of occupation tended to be less manual. Conclusions: Anti-obesity health policy interventions have to address to the parents and promote their active involvement, to effectively confront the alarming magnitude of the paediatric obesity problem in Greece.
