“…Among girls, lower scores in self-esteem and general self-efficacy were associated with higher screen-based sedentary behaviours. Melkevik et al25 reported that the use of electronic media was associated with increased BMI z -scores and higher odds of being overweight in boys and girls who did not follow the physical activity guidelines. Recent research23 found a negative association between sedentary behaviour and engagement in sports in adolescents.…”

“…This result was contrary to previous studies where a significant longitudinal correspondence between time spent on media use and increased body fat was observed from childhood to adolescence ( 29 ). However, in cross-sectional studies, the results were somewhat mixed: some reported no evidence of a significant association between use of media and BMI ( 24 , 29 ), and others reported that media use appeared to be positively associated with BMI for girls only ( 29 , 30 ). Taken together, these inconsistent results further suggest the need for more prospective longitudinal studies to evaluate the effect of media use, timing of last food intake, sleep hours, and unhealthy eating behavior on BMI.…”

IntroductionAdolescents spend a substantial amount of time consuming media, including watching television, playing video games, and using electronic devices to access the internet. We examined the relationship between prolonged media use on screen devices and its potential association with obesity through several mechanisms.MethodsWe used data from 659,288 eighth and eleventh grade students who participated in the 2015–2016 School Physical Activity and Nutrition (SPAN) survey in Texas to examine the associations between hours of media use per day and 3 behaviors related to obesity: timing of last food intake, unhealthy eating behavior, and sleep hours. Also, mediation analyses were conducted to examine the pathways between hours of media use and body mass index (BMI).ResultsCompared with adolescents who used media 2 hours or less per day, those who used media 6 hours or more had higher odds of nighttime eating (odds ratio [OR], 3.16; 95% confidence interval [CI], 1.76–5.66) and inadequate sleep (OR, 1.57; 95% CI, 1.05–2.36) and a higher coefficient for Unhealthy Eating Index score (3.87; 95% CI, 1.3–6.37). Mediation analysis demonstrated that for males sleep hours and timing of last food intake mediated the pathway between hours of media use and BMI. For females, unhealthy eating behavior mediated this pathway.ConclusionAdolescents who used electronic media 6 or more hours at night had higher odds of unhealthy eating behavior and inadequate sleep hours than those with 2 hours’ use or less. Attention to behaviors associated with adolescents’ prolonged media use is needed to reduce risk of obesity.

“…The few local studies that are available give some insight into the situation in only 9 counties out of 41. To this, data from studies performed abroad that included a Romanian cohort was included, but the exact geographical area of data collection is unclear in most cases [18,23,24,29]. Based on the information reviewed here, the prevalence of excess weight is in line with previous published data, namely 23.77% of children aged 2-19 have excess weight, 16.6% being overweight and 8.7% being obese (mean values based on WHO, CDC and IOTF derived prevalences, Table 4).…”

Introduction. Excess weight has been recognized as a global health issue for many years. It is an established risk factor for several chronic conditions, notably cardiovascular disease and diabetes, and is increasingly present in the pediatric population. The purpose of this paper is to review the existent local data regarding pediatric excess weight (including obesity) and its impact. Method. A review of existent literature from the year 2000 and onwards was performed. Only material referring to a Romanian cohort (or subgroup) was included. Results. Of the initial 455 identified records, 62 full text papers in English and Romanian were considered relevant to the topic and analyzed. A mean prevalence of excess weight of 31.6% (WHO), 18.35% (CDC) and 21.37% (IOTF) with obesity rates of 11.4% (WHO), 7.2% (CDC) and 7.69% (IOTF) was calculated. Several factors that could promote excess weight have been identified in Romanian cohorts and are presented. Possible complications are in line with previous published data and mainly involve the cardiovascular system and metabolic effects. Psychological obesity-associated issues have also been reported. Discussion. To our knowledge, there has not been a local study to assess the prevalence of pediatric excess weight at a country level. The available prevalence data is in line with both previous reports of Romanian data and international figures. There does not appear to be an increase in rates over time in the last few years. Systematic country-level attempts to tackle the excess weight problem are few, however smaller range communitybased intervention programs have been reported, with modest results. Conclusions. A worrying proportion of children are overweight or obese in Romania and this may lead to a variety of physical and psychological issues for the child. Conditions such as arterial hypertension and dyslipidemia, typically encountered in adults, are being noted with increased frequency in the pediatric population and their full impact on quality of life and life expectancy is difficult to grasp. Sustained, community-based interventions could possibly achieve a slow reduction in the rates of pediatric excess weight.
