Childhood obesity is associated with host factors that enhance susceptibility and environmental factors that increase food intake and decrease energy expenditure. Obese children underreport food intake and probably consume more food to maintain their weight at increased levels. Prevalence of obesity is related to family variables, including parental obesity, family size and age, and socioeconomic status. Television viewing is strongly associated with the prevalence of obesity through its impact on food intake and activity. How these environmental variables are behaviorally interrelated to the genesis of obesity is unclear.
儿童肥胖与增强易感性的宿主因素以及增加食物摄入量和减少能量消耗的环境因素相关。肥胖儿童往往少报食物摄入量，并且可能为了将体重维持在较高水平而摄入更多食物。肥胖的患病率与家庭变量有关，包括父母肥胖、家庭规模和年龄以及社会经济地位。看电视通过对食物摄入和活动的影响与肥胖患病率密切相关。这些环境变量在行为上如何与肥胖的发生相互关联尚不清楚。
