RESUMO

BACKGROUND: While excessive television viewing has been associated with negative outcomes in children's welfare, parental co-viewing has been suggested as an effective way to prevent these negative effects. The objective of the present study is to specify some social contexts of co-viewing and to assess whether co-viewing modifies the effects of media on children's TV-related fears. METHODS: The study is based on a representative random sample of 331 children aged 5-6 years. It is based on parental reports of children's TV-related fears and family television viewing practices. RESULTS: Parental co-viewing and discussion of television programmes with the child were found to be associated with higher rates of children's TV-related fears, high television exposure in general and watching adults' television programmes. The association between TV-related fears and co-viewing remained significant even after controlling for gender, maternal education, family income and the quantity and quality of television viewing. Co-viewing and TV-related discussions increased the risk for TV-related fears nearly fourfold (adjusted odds ratio 3.92, 95% confidence interval 1.37-11.17 and adjusted odds ratio 3.31, 95% confidence interval 1.33-8.20, respectively). CONCLUSIONS: The findings suggest that co-viewing and discussing television programmes are more common in families where television exposure is high. Because both co-viewing and discussing television programmes were associated with higher fear scores regardless of the quantity and quality of television exposure, the research shows that in everyday life co-viewing may not be done in such a way that it leads to a reduction of children's fears. More studies are needed to explore the co-viewing practices of families in more detail.

RESUMO

Despite the promise of intranasal oxytocin (OT) for modulating social behavior, recent work has provided mixed results. This may relate to suboptimal drug deposition achieved with conventional nasal sprays, inter-individual differences in nasal physiology and a poor understanding of how intranasal OT is delivered to the brain in humans. Delivering OT using a novel 'Breath Powered' nasal device previously shown to enhance deposition in intranasal sites targeted for nose-to-brain transport, we evaluated dose-dependent effects on social cognition, compared response with intravenous (IV) administration of OT, and assessed nasal cavity dimensions using acoustic rhinometry. We adopted a randomized, double-blind, double-dummy, crossover design, with 16 healthy male adults completing four single-dose treatments (intranasal 8 IU (international units) or 24 IU OT, 1 IU OT IV and placebo). The primary outcome was social cognition measured by emotional ratings of facial images. Secondary outcomes included the pharmacokinetics of OT, vasopressin and cortisol in blood and the association between nasal cavity dimensions and emotional ratings. Despite the fact that all the treatments produced similar plasma OT increases compared with placebo, there was a main effect of treatment on anger ratings of emotionally ambiguous faces. Pairwise comparisons revealed decreased ratings after 8 IU OT in comparison to both placebo and 24 IU OT. In addition, there was an inverse relationship between nasal valve dimensions and anger ratings of ambiguous faces after 8-IU OT treatment. These findings provide support for a direct nose-to-brain effect, independent of blood absorption, of low-dose OT delivered from a Breath Powered device.
