Abstract

OBJECTIVE

To investigate relationships between children's body mass index (BMI) and parent reports of children's television and video game/computer habits, controlling for other potential risk factors for paediatric obesity.

METHODS

Child BMI was calculated from measured height and weight collected in 1997 as part of a large, representative, cross-sectional study of children in Victoria, Australia. Parents reported the amount of time children watched television and used video games/computers, children's eating and activity habits, parental BMI and sociodemographic details.

RESULTS

A total of 2862 children aged 5-13 years participated. Child mean BMI z-score was significantly related to television (F = 10.23, P < 0.001) but not video game/computer time (F = 2.23, P = 0.09), but accounted for only 1 and 0.2% of total BMI variance, respectively. When parental BMI, parental education, number of siblings, food intake, organized exercise and general activity level were included, television ceased to be independently significantly related to child BMI. Using adjusted logistic regression, the odds of being overweight and obese generally increased with increasing television viewing. No relationship was found for video game/computer use.

CONCLUSIONS

A small proportion of variance in child BMI was related to television, but not video game/computer time. This was far outweighed by the influence of other variables. Causal pathways are likely to be complex and interrelated.

摘要

目的

研究儿童体重指数（BMI）与家长报告的儿童看电视及玩电子游戏/使用电脑习惯之间的关系，并控制其他儿童肥胖的潜在风险因素。

方法

儿童BMI根据1997年测量的身高和体重计算得出，这些数据是澳大利亚维多利亚州一项大型、具有代表性的儿童横断面研究的一部分。家长报告了孩子看电视和玩电子游戏/使用电脑的时间、孩子的饮食和活动习惯、家长BMI以及社会人口学细节。

结果

共有2862名5至13岁的儿童参与。儿童平均BMI z评分与看电视时间显著相关（F = 10.23，P < 0.001），但与玩电子游戏/使用电脑时间无关（F = 2.23，P = 0.09），且分别仅占BMI总方差的1%和0.2%。当纳入家长BMI、家长教育程度、兄弟姐妹数量、食物摄入量、有组织的运动和一般活动水平时，看电视与儿童BMI不再独立显著相关。使用调整后的逻辑回归分析，超重和肥胖的几率通常随着看电视时间的增加而增加。未发现玩电子游戏/使用电脑与超重和肥胖有关。
