“…To the contrary, in a recent study with 2044 adolescent participants from urban areas of nine different European countries (i.e., Austria, Belgium, France, Germany, Greece, Hungary, Italy, Spain and Sweden), Vanhelst et al [ 15 ] observed a much higher overall overestimation rate (82,9%), very similar to the one obtained in this study (84,9%), while they did not differentiate by gender. Even if, based on this scant existing evidence, it might be premature to try to establish a firm conclusion regarding the influence of gender on the tendency among adolescents to overestimate PA, the results obtained herein would seem to be more in line with previous findings which have constantly recorded lower activity levels and more negative perceptions regarding said activity in girls [ 44 , 45 ].…”

The imbalances between the actual physical activity (PA) of adolescents and the subjective perception both they and their parents have in this regard can play an important role in perpetuating inactive lifestyles. The aim of this study is to analyse these discrepancies by considering gender as a conditioning factor. The participants in the study were 1697 adolescents, 1244 mothers and 1052 fathers in the educational communities of 26 secondary schools located in urban environments of the Autonomous Community of Galicia (Spain). With regard to actual physical activity, a high prevalence of sedentarism (82.1%) was revealed, this being even more acute in girls (87.8%). However, the perceived levels of activity differed significantly from the actual ones with a clear general overestimation both by the adolescents and their parents. When further exploring the data, gender influences were also detected both in adolescent and parental perceptions, since the high rates of overestimation in sedentary individuals were lower in girls and, on the contrary, the low rates of underestimation in active individuals were higher in girls. Moreover, although the level of agreement between actual and perceived physical activity was low overall, with Cohen’s kappa values ranging from 0.006 to 0.047, the lowest values were observed in the case of girls. In conclusion, both the adolescents and their parents were incapable of correctly assessing the actual physical activity of the former, so it seems that the general population lacks knowledge about the amount of physical activity that adolescents need to do to achieve a healthy lifestyle. Consequently, it would be advisable to implement health education campaigns and awareness-raising interventions directed to young people as well as to their parents and, in doing so, gender must be considered by establishing distinct program designs in terms of this variable.

“…The results of the study demonstrate that the education of the parents significantly affects food waste: the more extensive the parents' education are, the less food is wasted. Studies of middle school students confirm that sex is a differentiating factor relative to knowledge and food behavior (Gaylis et al, 2017). Nevertheless, our results indicate that the discarding of food has no relation to sex.…”

Purpose According to a study by European Commission, 88m tons of food waste are generated per year, of which 46.5m tons are wasted by households. Households still remain the main source of food waste (53 percent). The purpose of this paper is to estimate households’ food waste and wastage-related losses of energy and nutrients among middle school students as well as assess educational intervention regarding food waste prevention. Design/methodology/approach The study included 555 students from 11 schools in Poland. The study was conducted using the survey questionnaire and the three-day record of food waste. The interventional group filled a questionnaire before and after of education as well as after three months of intervention. Findings Students waste 23 g of food per day. The most wasted products are: potatoes, bread, fruits and vegetable as well as meet and ham. Energy losses from leftovers are less than 1–10 percent. Losses of nutritional value along with wastages were the highest for vitamin C, but also for dietary fiber, potassium and folate. Food waste education was nearly twice as strong in study group with films intervention, than those who received only a leaflet for parents. Research limitations/implications Middle school students are responsible for households’ food waste and contribute to energy and nutrition losses. Educational intervention is more effective, while using multimedia methods and need to be continued. Practical implications The paper is a scientific study and addressed to the scientific audience. However, due to the problem of households’ food waste, general public could be also interested. Social implications Food waste is an element of waste management. Studying the scale of food waste and waste related behavior can help to better understand causes of food waste. The search for ways to limit food waste, through education address to young people, can be an effective method of prevention of waste. The UN has established 17 new development goals for the years 2015–2030 (United Nations, 2015). One of them (Goal 12) is focused on ensuring sustainable consumption and production. It means halving food waste at the retail and consumer levels and food losses at the production and post-harvest stages by 2030. Originality/value There are few publications available about food waste including energy and nutrients waste. This study shows the scale of household waste, the quantity and type of wasted products and causes of disposal. Also, the way of handling with food waste at homes was examined. It is also important to draw attention to the responsibility of young people in wasting food, which was examined in the paper.

Screen time (ST) not only affects physical activity but can also be associated with dietary behaviors. Both of these factors determine the health and development of adolescents. The aims of the study were: 1. to analyze the relationship between ST and nutritional behaviors among adolescents; 2. to examine this association in relation to body weight status. Data on the ST duration and nutritional behaviors were collected using a questionnaire. Body mass status was assessed based on weight and height measurements. A total of 14,044 students aged 13–19 years old from 207 schools participated in the study. A significant relationship between ST and gender, age and type of school was observed, but not body weight status. The average ST duration increased with age (from 2.6 h among 13 years old to 3.2 h among 19 years old), and was significantly higher among boys in all age categories (2.7 h vs. 2.5 h in the youngest age group, and 3.5 h vs. 3.0 h in the oldest age group, respectively). The chance for meeting the recommendation for ST in a group of girls (regardless of age) was almost 50% higher compared to boys. Meeting ST recommendation (≤2 h) was associated with a greater odds ratio for favorable nutritional behaviors in the whole group, with exception of drinking milk or milk beverages, and significantly reduced the odds ratio of adverse dietary behaviors (drinking sweet beverages, consumption of sweets and fast food) in the whole group and by gender. More research is needed to clarify the possible cause-and-effect relationships between ST and dietary behaviors.
