It has been reported that television (TV) viewing is associated with childhood obesity in Western countries. The present study aimed to investigate the relationship between obesity and eating habits while watching TV among primary-school children in the Middle East.
Cross-sectional.
Children were recruited from primary schools of four educational districts in Shiraz, Iran. Anthropometric indices of mass (kg) and height (m) were measured, and BMI (percentile) was calculated. Demographic characteristics, TV viewing behaviours and physical activity data were collected from parents during face-to-face interviews and a 3d dietary record was completed. Subject Children (n 607) aged 6-10 years.
Mean (sd) age of children was 8·16 (1·37) years, of whom 9·1 and 8·4 % were overweight and obese, respectively. Children who spent ≥2 h watching TV on weekdays (OR=1·99; 95 % CI 1·09, 3·60) and weekend days (OR=1·86; 95 % CI 1·01, 3·43) had higher odds of being obese, even after adjusting for physical activity. Children who ate breakfast while watching TV had higher odds of being overweight v. those who did not watch TV while eating breakfast (OR=2·70; 95 % CI 1·02, 7·60). There were no associations between TV viewing during other meals (lunch and dinner) and overweight/obesity.
TV viewing for ≥2 h daily increases the risk of being obese in Iranian children aged 6-10 years, independent of physical activity. Further, breakfast consumption while watching TV may increase the risk of overweight/obesity, independent of total TV viewing time.
有报道称，在西方国家，看电视与儿童肥胖有关。本研究旨在调查中东地区小学生在看电视时肥胖与饮食习惯之间的关系。
横断面研究。
参与者从伊朗设拉子四个教育区的小学招募。测量体重（kg）和身高（m）的人体测量指数，并计算 BMI（百分位）。通过面对面访谈和 3 天饮食记录收集父母的人口统计学特征、看电视行为和身体活动数据。研究对象为 6-10 岁的儿童（n=607）。
儿童的平均（标准差）年龄为 8.16（1.37）岁，分别有 9.1%和 8.4%的儿童超重和肥胖。在工作日（OR=1.99；95%CI 1.09，3.60）和周末（OR=1.86；95%CI 1.01，3.43）每天看电视时间≥2 小时的儿童肥胖的可能性更高，即使在调整了身体活动后也是如此。边看电视边吃早餐的儿童超重的可能性更高，而不吃早餐时看电视的儿童则超重（OR=2.70；95%CI 1.02，7.60）。在其他用餐时间（午餐和晚餐）看电视与超重/肥胖之间没有关联。
伊朗 6-10 岁儿童每天看电视时间≥2 小时会增加肥胖的风险，与身体活动无关。此外，边看电视边吃早餐可能会增加超重/肥胖的风险，与总看电视时间无关。
