Television viewing (TVV) is associated with obesity in children, suggesting that TVV decreases activity and increases energy intake. However the effect of TVV on satiety and satiation in children has only recently been investigated. We reported that TVV at mealtime reduced satiety and increased food intake (FI) in 9 – 14 y old boys after a pre‐meal glucose drink (Bellissimo et al , 2007). Therefore, we examined the effect of TVV at mealtime and pubertal status on appetite and FI in girls (9 – 14 y) after a glucose drink. Following a randomized, counterbalanced design, 25 girls received equally sweetened drinks containing sucralose or glucose (1.0 g/kg body weight) in 250 mL of water 2 h after a standard breakfast. FI from an ad libitum pizza meal was measured 30 min later with or without TVV. Appetite was measured over the entire study. Glucose reduced FI more when the girls ate without vs. with TVV (24 vs. 10%, p < 0.001). However, there was an interaction with pubertal status. Glucose reduced FI by 21% in the peripubertal girls (n = 17) without TVV (p = 0.029), but not with TVV. Conversely, in the postpubertal girls (n = 8), glucose reduced FI (~ 30%, p < 0.001), with or without TVV. Appetite was not altered by drink or TVV, but was correlated with FI at 30 min (r = 0.34, p = 0.001). Thus, TVV at mealtime reduced physiological responses to the pre‐meal glucose drink and delayed satiation during the meal in peripubertal, but not postpubertal, girls.
