Childhood obesityChildhood is one of most important risk factors for incidence of cardiovascular disease and diabetes in adulthood. Childhood not only is common in developed countries but increasingly affects developing countries. Because of consequences of childhood -- in adulthood, cardiovascular disease, diabetes, arthritis -- has become one of leading causes of death in world (Rapport sur I'organisation de la recherche ..., 2010).Childhood has taken form of an epidemic since mid-1990s (Rapport sur I'organisation de la recherche..., 2010). One single indicator, Body Mass Index (BMI), usually determines adult obesity. It is calculated as ratio of weight in kilograms to square of height in meters. Individuals whose BMI is 25 to 29.9 are diagnosed as being overweight. The diagnosis of of first degree is made when BMI is 30 to 34.9; of second degree is pronounced when BMI is 35 to 40. Morbid obesity is diagnosed when BMI is over 40. In case of children it is not enough to know only BMI; it is necessary to correlate it with an interval of rate of growth for relevant age. For example, in France about 10% of children (from 3 to 16 years old) are obese, and about 19% are overweight (Sassi, Cecchini, & Devaux, 2012).A report of Institut national de la recherche agronomique (France) (2010) indicated that number of children who were overweight didn't change from 1997 to 2007. According to Ministry of Health in Russia, about 19.6% of boys and 5.5% of girls from 5 to 15 years old are overweight, while in Moscow number of children with a BMI above norm is 30% more than in other regions (Briz, 2008).These statistics suggest a joyless future. Taking into account that the chance that a child suffering from will continue this pathology in adulthood ranges from 20 to 50%, if is diagnosed before adolescence; if diagnosis of is made for a teenager, this probability varies from 50% to 70% (Branca, Nikogosian, & Lobstein, 2007, p. 23). We can suggest that level of diseases (diabetes, cardiovascular disease, arthritis) associated with in adulthood will also increase, and they will be manifested at an increasingly early age (Prevention, depistage ...,2012).Studies that identify factors associated with show that a lack of physical activity and an unbalanced diet are main direct factors. Genetic factors are responsible for 1% to 6% of childhood (Klump, Kaye, & Strober, 2001). The economic and socioprofessional situation of parents is also associated with children's being overweight or obese, as are low income, poor social environment, and low parental education (Institut national de la recherche agronomique, 2010).Videogames in childhood: Do they matter?Videogames are based on approaches to play in human development. The effect of play on general child development is a running theme for some of most prominent educational psychologists. Play creates possibilities for children to (a) have social experiences and simulate alternative emotional states and feelings, which can then bring about resolution outside play context (Erikson, 1977), (b) reproduce real-life dilemmas and complicated situations and then work out perfect resolutions and overcome unpleasant feelings (Piaget, 1962), (c) have a basis for fostering development of social cognition (Piaget, 1962; Vygotsky, 19301934/1978).Today, games, gamifications, and videogames in particular have a primary role as media of human development. Previous decades saw an expanding role for new media in area of psychosocial development in childhood. As a medium for entertainment and education, videogames constitute a multi-billion-dollar industry. They are, for example, present in two of three U. …
