This study examines the development of television (TV) behaviors across the first 18 months of life and identifies maternal and infant predictors of infant TV exposure.
We used longitudinal TV exposure, maternal sociodemographic, and infant temperament data from 217 African-American mother-infant pairs participating in the Infant Care and Risk of Obesity Study. Longitudinal logistic models and ordered regression models with clustering for repeated measures across subjects adjusted for infant gender and visit were used to assess maternal and infant predictors of TV exposure and to test whether infants with both maternal and infant risk factors had higher odds of more detrimental TV exposure.
Infants as young as 3 months old were exposed to an average of 2.6 hours of TV and/or videos daily, and nearly 40% of infants were exposed to >3 hours of TV daily by 12 months of age. Maternal TV viewing and maternal obesity and infant activity, fussiness, and crying were associated with greater infant TV exposure, whereas maternal education and infant activity were associated with having the TV on during most meals. Infants perceived as being more active or fussier had higher TV exposure, particularly if their mothers also had risk factors for higher TV exposure.
Understanding the characteristics that shape TV exposure and its biological and behavioral sequelae is critical for early intervention. Maternal perception of infant temperament dimensions is related to TV exposure, suggesting that infant temperament measures should be included in interventions aimed at limiting early TV.
本研究考察了婴儿生命的头 18 个月中电视(TV)行为的发展,并确定了母亲和婴儿预测婴儿 TV 暴露的因素。
我们使用了来自 217 对参加婴儿护理和肥胖风险研究的非裔美国母婴对的纵向 TV 暴露、母亲社会人口统计学和婴儿气质数据。使用纵向逻辑回归模型和有序回归模型,对受试者的重复测量进行聚类调整,以评估母婴预测因素与婴儿的 TV 暴露,并测试是否存在母婴危险因素的婴儿更有可能受到更不利的 TV 暴露。
3 个月大的婴儿平均每天暴露于 2.6 小时的电视和/或视频,并且近 40%的婴儿在 12 个月大时每天暴露于>3 小时的电视。母亲看电视、母亲肥胖和婴儿的活动、烦躁和哭泣与婴儿的 TV 暴露有关,而母亲的教育程度和婴儿的活动与在大多数进餐时间打开电视有关。被认为更活跃或更烦躁的婴儿的 TV 暴露更高,特别是如果他们的母亲也有更高的 TV 暴露风险因素。
了解塑造 TV 暴露及其生物学和行为后果的特征对于早期干预至关重要。母亲对婴儿气质维度的感知与 TV 暴露有关,这表明应将婴儿气质测量纳入旨在限制早期 TV 暴露的干预措施中。
