OBJECTIVES The primary objective was to examine associations between mothers' television and mobile device (TV/MD) use and responsive feeding during an observed mother-toddler mealtime interaction. The secondary objective was to assess whether dimensions of child temperament were associated with mothers' TV/MD use. METHODS Participants from a prenatal lifestyle intervention trial to prevent excess gestational weight gain among women with overweight and obesity (N = 77) were observed during a dinner-time meal when their children were aged 19.4 ± 0.9 months. Trained video coders used the Responsiveness to Child Feeding Cues Scale to rate child strength of early/subtle, positive active, and negative active satiation cues and maternal responsiveness to these cues. Coders also recorded mothers' use of TV/MD. Child temperament was reported by mothers through the Infant Behavior Questionnaire-Revised Very Short Form. RESULTS Twelve percent (n = 9) of mothers used TV/MD during the mealtime interaction. Children whose mothers used TV/MD exhibited stronger early/subtle cues (4.1 ± 0.4) compared with children whose mothers did not use TV/MD (3.4 ± 0.2; p = 0.04). Mothers who used TV/MD exhibited significantly lower responsiveness to child satiation cues (2.0 ± 0.4) than those who did not use TV/MD (3.4 ± 0.2; p = 0.001). Greater child temperamental negative affectivity was associated with a greater likelihood of maternal TV/MD use (OR = 4.80, 95% CI = 1.21, 19.03). CONCLUSION Mothers' TV/MD use was associated with greater child temperamental negative affectivity and lower responsiveness to child cues.

先前产前干预参与者中技术使用、反应性喂养和儿童气质之间的关联。

目的 主要目的是在观察到的母婴进餐互动期间，检查母亲电视和移动设备 (TV/MD) 使用与响应性喂养之间的关联。第二个目标是评估儿童气质的维度是否与母亲电视/MD的使用有关。方法 一项旨在防止超重和肥胖女性 (N = 77) 妊娠期体重过度增加的产前生活方式干预试验的参与者在其孩子 19.4 ± 0.9 个月大时的晚餐期间进行观察。训练有素的视频编码员使用对儿童喂养线索的反应量表来评估儿童对早期/微妙、积极主动和消极主动饱足线索的强度以及母亲对这些线索的反应能力。编码人员还记录了母亲对电视/MD 的使用情况。母亲通过婴儿行为问卷修订版非常简表报告儿童气质。结果 12% (n = 9) 的母亲在进餐互动期间使用电视/MD。与母亲不使用 TV/MD 的孩子 (3.4 ± 0.2；p = 0.04) 相比，母亲使用 TV/MD 的孩子表现出更强的早期/微妙线索 (4.1 ± 0.4)。使用 TV/MD 的母亲对儿童饱足感线索的反应性 (2.0 ± 0.4) 显着低于不使用 TV/MD 的母亲 (3.4 ± 0.2；p = 0.001)。儿童气质负面情绪越大，母亲使用 TV/MD 的可能性越大（OR = 4.80，95% CI = 1.21，19.03）。结论 母亲使用电视/MD 与孩子气质上的负面情绪较高以及对孩子暗示的反应较低有关。
