Association between the time spent watching television and the sociodemographic characteristics with the presence of overweight and obesity in Colombian adolescents (secondary analysis of the ENSIN 2010)

Abstract

Objective To determine the association between the time spent watching television and the sociodemographic characteristics with the presence of overweight and obesity in Colombian adolescents. Materials and methods Secondary analysis of the information obtained in the National Survey of the Nutritional Situation 2010 of Colombia, in a probabilistic sample of 18177 adolescents with an age range between 13 and 17 years. The time spent watching television and / or videogames and sociodemographic factors was determined. Anthropometric markers and body composition were recorded. Associations were established through logistic regression models. Results The prevalence of overweight was 13.0% (95% CI 12.4–13.8) and obesity was 3.0% (95% CI 2.8–3.3). The prevalences of overweight and obesity were higher in adolescent women [16.6% (95% CI 15.8–17.5) and 3.4% (95% CI 3.1–3.7), respectively]. Overweight and obesity were associated with being female [OR 1.94 (95%CI 1.77–2.12) and OR 1.29 (95%CI 1.09–1.53), respectively], high socioeconomic level [OR 1.22 (95%CI 1.10–1.36) and OR 1.47 (95%CI 1.19–1.81), respectively], reside in urban area [OR 1.13 (95%CI 1.03–1.24) and OR 1.47 (95%CI 1.21–1.79), respectively]. Being indigenous was associated with being overweight [OR 1.25 (95%CI 1.10–1.42)], while being Afro-Colombian was associated with obesity [OR 1.33 (95%CI 1.05–1.69)]. Watching television and / or video games for two or more hours a day [OR1.17 (95%CI 1.06–1.30)] was associated with being overweight; whereas watching television every day of the week was associated with obesity [OR 1.66 (95%CI 1.13–2.43)]. Conclusions The population studied has a significant prevalence of overweight and obesity, being overweight is associated with being a woman, a high socioeconomic status, residing in an urban area, having an indigenous ethnicity, watching television for three days during the week and looking at more than two hours of television in a day; Obesity is associated with being a woman, a medium-high and high socioeconomic status, residing in an urban area, Afro-Colombian ethnicity, watching television at least once in the last week and watching television every day during the last week.

RETRACTED: Screen Time and Body Mass Index Among Children and Adolescents: A Systematic Review and Meta-Analysis

“…While it has been reported that BMI is one of the simplest and extensively used screening tool for child and adult obesity and it is not only used as an outcome measure for determining obesity but also as a useful anthropometric index for cardiovascular risk ( 30 ). Also, because of its simplicity, BMI is a standard tool to diagnose overweight/obesity as declared by WHO ( 6 , 31 ).…”

Adolescence Obesity Risk Increases with Increased Screen Time: A Systematic Review and Dose-Response Meta-Analysis

“…Internet addicted adolescents had also elevated risk of obesity in one study [19]. However, several other studies reported no signi cant association between obesity and screen time was observed [22,27,47]. The possible strong reason for this inconsistency, is the type of screen (e.g.…”

“…TV, video games or personal computer and so on) that is used in numerous studies. For nding the answer, we performed subgroup analysis; according to the results, those studies that de ned video games as their screen failed to reveal a positive association between screen time and obesity [23,47,58]. In the study by Franceschin MJ et al [16] adolescents with watching TV more than two hours per day had almost doubled chance of being obese compared with those who had less than 2 hours per day TV watching (OR = 1.73; 95%CI = 1.24-2.42) while the association was not signi cant for video game playing or PC use.…”

“…The study by Zul qar T [25], provided results for TV use in weekdays, electronic game playing in weekdays, TV use in weekends and electronic game playing in weekends among immigrant boys and girls from high income and lower than middle income countries separately; therefore, the results were included as six studies in the analysis. In the studies by Pabon et al [47] and Haidar A et al [21], the results were reported separately for overweight and obesity. The study by Saha M et al [23] reported the results for PC, TV and video games separately.…”

Association between television viewing and early childhood overweight and obesity: a pair-matched case-control study in China

“…In previous research that focused on the association between TV viewing and childhood overweight and obesity, the results were inconsistent. In some studies, a positive association was observed between long TV viewing time and childhood obesity [12–14] and in several studies, a dose-response effect between TV viewing time and childhood body mass index (BMI) was indicated [15, 16]. However, in other studies, an association between TV viewing time and childhood obese status was not observed [17, 18].…”
