“…Among case-control studies (see Table 1), higher durations of screen time (4/4 studies) and TV viewing (2/2 studies) were significantly associated with being in the overweight/obese or case group compared with the control group (Al-Ghamdi 2013;Huang et al 2013;Xi et al 2011;Yi et al 2012;Zurriaga et al 2011). Significant associations were only observed for weekends and not weekdays in 1 study (Al-Ghamdi 2013).…”

This systematic review is an update examining the relationships between objectively and subjectively measured sedentary behaviour and health indicators in children and youth aged 5-17 years. EMBASE, PsycINFO, and Medline were searched in December 2014, and date limits were imposed (≥February 2010). Included studies were peer-reviewed and met the a prioridetermined population (apparently healthy children and youth, mean age: 5-17 years), intervention (durations, patterns, and types of sedentary behaviours), comparator (various durations, patterns, and types of sedentary behaviours), and outcome (critical: body composition, metabolic syndrome/cardiovascular disease risk factors, behavioural conduct/pro-social behaviour, academic achievement; important: fitness, self-esteem) study criteria. Quality of evidence by outcome was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework. Due to heterogeneity, a narrative analysis was conducted. A total of 235 studies (194 unique samples) were included representing 1 657 064 unique participants from 71 different countries. Higher durations/frequencies of screen time and television (TV) viewing were associated with unfavourable body composition. Higher duration/frequency of TV viewing was also associated with higher clustered cardiometabolic risk scores. Higher durations of TV viewing and video game use were associated with unfavourable behavioural conduct/pro-social behaviour. Higher durations of reading and doing homework were associated with higher academic achievement. Higher duration of screen time was associated with lower fitness. Higher durations of screen time and computer use were associated with lower self-esteem. Evidence ranged from "very low" to "moderate" quality. Higher quality studies using reliable and valid sedentary behaviour measures should confirm this largely observational evidence.Key words: sitting, TV, screen time, body composition, fitness, metabolic syndrome, cardiovascular disease, self-esteem, pro-social behaviour, academic achievement. Résumé :Cette analyse documentaire systématique est une mise à jour de la relation entre la mesure objective/subjective des comportements sédentaires et les indicateurs de santé chez les enfants et les jeunes âgés de 5 à 17 ans. En décembre 2014, on cherche dans ASE, PsycINFO et Medline, mais on impose une limite de date (≥février 2010). Les études retenues sont sanctionnées par des pairs et sont conformes aux critères a priori déterminés dans l'étude : la population (des jeunes apparemment en bonne santé âgés de 5 à 17 ans), l'intervention (durée, habitudes et types de comportement sédentaire), la comparaison (durées variées, habitudes et types de comportement sédentaire) et le résultat (essentiel : composition corporelle, syndrome métabolique/ facteurs de risque de maladie cardiovasculaire, comportement/comportement prosocial, rendement scolaire; important : condition physique, estime de soi). La qualité des données probantes est évaluée pour chaque résultat pa...

“…Females are more concerned about their weight and body shape. Among males, a strong and big body in particular is considered healthy in northeast China.Many epidemiological studies have indicated that short sleep duration is a risk factor of being overweight or obese among children and adolescents (10,(25)(26)(27)(28)(29). In a cross-sectional study of 8,274 children aged 6-7 y, Sekine et al found that the adjusted Articles Guo et al CNY, Chinese yuan (1 CNY = 0.163 USD); OR, odds ratio; USD, US dollar; 95% CI, 95% confidence interval.…”

Prevalence and risk factors of being overweight or obese among children and adolescents in northeast China

Background:We determined the prevalence and risk profiles of being overweight or obese among children and adolescents in rural northeast China. Methods: We conducted a cross-sectional study consisting of 4,094 children and adolescents aged 5-18 y. Anthropometric measurements and information on health-related variables were collected by well-trained personnel. Odds ratios (ORs) are presented with 95% confidence intervals (CIs). results: The overall prevalence of subjects who were overweight or obese was 21.8% (15.4% overweight and 6.4% obese). Among boys, getting more sleep was found to be a protective factor against being overweight or obese, and a higher monthly family income (2,000-5,000 Chinese yuan (CNY); 1 CNY = 0.163 US dollar) was associated with an increased risk as compared with lower incomes. For girls, not having breakfast every day conferred higher odds of being overweight or obese (OR, 1.45 (95% confidence interval (CI), 1.11-1.91)). When both parents were overweight, this increased the risk of a child being overweight or obese in both boy (overweight father: OR, 1.54 (95% CI, 1.26-1.89); overweight mother: OR, 1.73 (95% CI, 1.35-2.22)) and girl participants (overweight father: OR, 2.01 (95% CI, 1.57-2.57); overweight mother: OR, 1.45 (95% CI, 1.07-1.96)). conclusion: The prevalence of pediatric obesity in rural China was relatively high. Risk profiles should be fully considered when planning prevention and treatment programs for pediatric obesity. t he prevalence of children and adolescents who are overweight or obese has increased dramatically and reached alarming levels in recent years, affecting both developed and developing countries. Given the adverse health consequences in young adults that are associated with being overweight or obese, such as metabolic disorders, type 2 diabetes, hypertension, sleep apnea, adulthood obesity, and higher rates of mortality in young adults (1-5), it has become a global public health problem that requires more attention worldwide.This trend of rising prevalence has been observed in China. In the most developed metropolises, including Beijing and Shanghai, the prevalence of overweight or obese children increased twofold to threefold between and 1995 . During 2005-2010, the increase rate of pediatric obesity was even higher in rural areas than that in urban areas (6,7).Although the genetic cause for obesity is not to be ignored, lifestyle behaviors and environmental factors are more likely to be closely related to the increased prevalence of overweight problems in the population. Several studies in China have suggested that lifestyle and sociodemographic factors such as watching too much TV, living in rural areas, and having overweight parents, increases the risk that children and adolescents will be overweight or obese (8)(9)(10)(11). Because the management of bodily weight problems in this segment of the population is often based on lifestyle modifications, identification of the associated risk factors is a top priority.The prevalence of childhood and adoles...

“…This study determined that a birth weight above 4,000 grams was not a significant risk factor for being overweight and obesity, like another study conducted in China (34). However, certain studies conducted in Turkey have suggested that birth weight above 4,000 grams was a risk factor for obesity (4,13).…”

Background: Obesity in children and adolescents is a serious public-health concern, and obesity research has become an important field of study. Objectives: The aim of this study was to determine the prevalence and risk factors of overweight and obesity in elementary-school children from the first to eighth grade. Methods: This is a descriptive, cross-sectional study. The research sample included 3,028 children from seven elementary schools selected according to stratified random sampling. The data were obtained using a demographic form and a 25-question survey. Each child's height and weight were measured by the researchers. The data were analyzed by frequency and logistic regression in the statistical package for the social sciences and Excel programs. Results:The children were all between 5 and 15 years old. 51.2% of the children were male, 13.4% were overweight (between 85 and 95th percentile) according to the Body Mass Index, and 8.7% were obese (above 95th percentile).
