The aim of this study was to investigate the effects of TV, magazines, radio, and internet following on body mass index (BMI) and obesity-related literacy among adults.
In this cross-sectional study, the subjects were recruited from an outpatient center in the city of Sombor, Serbia during Mar-Apr 2013. We collected data by a questionnaire from 657 (397 women; 59%) subjects, aged from 18 to 87 yr (Mean = 45; SD =14). The questionnaire consisted of personal data, body height and weight, frequency of television, radio, magazines and internet following and personal opinion on the impact of smoking, alcohol consumption, stress and physical inactivity on obesity.
Spearman's rank correlation analysis showed that BMI increased with longer TV viewing with a very weak strength of the correlation (r=0.104; =0.009) and decreased with more internet following with a weak strength of the correlation (r=-0.200: <0.001). Multiple linear regression analysis revealed that only internet use had a significant independent effect on BMI. The frequency rise of internet following from "rare" to "often" and "every day" decreased BMI by 0.5 per each grade. Internet followers showed a significantly better knowledge of the importance of smoking ( = 0.003), alcohol consumption (<0.001) and physical inactivity (=0.004) for obesity in comparison to non-followers.
Internet is the only media that independently and positively influence weight control and the literacy on obesity among adults.
本研究旨在调查电视、杂志、广播和网络关注对成年人身体质量指数（BMI）及肥胖相关知识水平的影响。
在这项横断面研究中，研究对象于2013年3月至4月从塞尔维亚索姆博尔市的一个门诊中心招募。我们通过问卷调查收集了657名（397名女性；59%）年龄在18至87岁（平均 = 45岁；标准差 = 14岁）的研究对象的数据。问卷包括个人资料、身高和体重、电视、广播、杂志和网络关注的频率，以及对吸烟、饮酒、压力和缺乏体育活动对肥胖影响的个人看法。
斯皮尔曼等级相关分析显示，BMI随着看电视时间延长而增加，相关性非常弱（r = 0.104；P = 0.009），而随着网络关注增多而降低，相关性较弱（r = -0.200；P < 0.001）。多元线性回归分析显示，只有网络使用对BMI有显著的独立影响。网络关注频率从“很少”升至“经常”和“每天”，BMI每个等级降低0.5。与非网络关注者相比，网络关注者对吸烟（P = 0.003）、饮酒（P < 0.001）和缺乏体育活动（P = 0.004）对肥胖影响的认识明显更好。
网络是唯一对成年人的体重控制和肥胖知识水平有独立且积极影响的媒体。
