Sedentary behaviour continues to be associated with unhealthy diet in young people in mostly cross-sectional studies .
BACKGROUND Sedentary behaviour and its association with dietary intake in young people and adults are important topics and were systematic ally review ed in 2011 .
There is a need to up date this evidence given the changing nature of sedentary behaviour and continued interest in this field .
This review aims to assist research ers in better interpreting the diversity of findings concerning sedentary behaviour and weight status .
OBJECTIVE To provide an up date of the associations between sedentary behaviour and dietary intake across the lifespan .
Television watching increases motivated responding for food and energy intake in children.
BACKGROUND Sedentary activities , such as watching television , may disrupt habituation to food cues , thereby increasing motivation to eat and energy intake . OBJECTIVE These experiments were design ed to examine the effect of television watching on habituation of ingestive behavior in children . DESIGN In experiment 1 , all children worked for access to cheeseburgers in trials 1 - 7 ( habituating stimulus ) . In trials 8 - 10 , children in the control group continued to work for cheeseburgers without any dishabituating stimuli , whereas children in the other groups received either a novel food ( French fries ) or television as dishabituating stimuli . Responding for food and amount of food eaten were measured . In experiment 2 , all children had access to 1000 kcal of a preferred snack food . One group watched a continuous television show , and the control groups either watched no television or watched a repeated segment of a television show , which controls for the television stimulus but requires reduced allocation of attention . RESULTS In experiment 1 , both the novel food and the television watching groups reinstated responding for food ( P = 0.009 ) and increased the amount of energy earned ( P = 0.018 ) above the level of the control subjects . In experiment 2 , the continuous television group spent more time eating ( P < 0.0001 ) and consumed more energy than the no television and the repeated segment groups ( P = 0.007 ) . CONCLUSION These experiments show that television watching can dishabituate eating or disrupt the development of habituation , which may provide a mechanism for increased energy intake associated with watching television
