Do Verbal Interactions with Infants During Electronic Media Exposure Mitigate Adverse Impacts on their Language Development as Toddlers?

The goal of this study was to determine whether verbal interactions between mothers and their 6-month-old infants during media exposure ('media verbal interactions') might have direct positive impacts, or mitigate any potential adverse impacts of media exposure, on language development at 14 months. For 253 low-income mother-infant dyads participating in a longitudinal study, media exposure and media verbal interactions were assessed using 24-hour recall diaries. Additionally, general level of cognitive stimulation in the home [StimQ] was assessed at 6 months and language development [Preschool Language Scale-4] was assessed at 14 months. Results suggest that media verbal interactions play a role in the language development of infants from low-income, immigrant families. Evidence showed that media verbal interactions moderated adverse impacts of media exposure found on 14-month language development, with adverse associations found only in the absence the these interactions. Findings also suggest that media verbal interactions may have some direct positive impacts on language development, in that media verbal interactions during the co-viewing of media with educational content (but not other content) were predictive of 14-month language independently of overall level of cognitive stimulation in the home.     

The role of depression symptoms in dialysis withdrawal.

Among end-stage renal disease (ESRD) patients on hemodialysis, death from withdrawal from life-sustaining dialysis is increasingly common. The present study's objective was to examine depression as a potential risk factor for hemodialysis withdrawal. Two hundred forty ESRD hemodialysis (133 male and 107 female) patients were followed for an average of 4 years after depression symptom assessment. Of these, 18% withdrew from dialysis. Using multivariate survival analysis and after controlling for the effects of age (p < .001) and clinical variables, the authors found that level of depression symptoms was a unique and significant predictive risk factor for the subsequent decision to withdraw from dialysis (p < .05). The potential impact that depression may have on the decision to withdraw from hemodialysis should be considered by health care providers, patient families, and patients.     

Sleep Architecture in Infants of Substance‐Abusing Mothers

This longitudinal, year‐long study compared sleep–wake state organization in two groups of infants–infants whose mothers abused substances during their pregnancies and nonexposed, typically developing, age‐matched comparison infants–to determine whether differences in sleep–wake state organization existed between the two groups. Seventeen infants of mothers who were participating in a parent–infant residential treatment program for substance abuse were enrolled. Their sleep–wake state organization over the first year of life was compared to that of 17 age‐matched comparison infants. The intent was to follow each infant on five occasions over the first year of life using established methods of time‐lapse videosomnography to record sleep–wake state organization; however, attrition in the substance‐abusing group was problematic. Some sleep–wake variables (i.e., Active Sleep%, Quiet Sleep%, Awake%, number of nighttime awakenings) were similar for both groups of infants at comparable ages across the first year. Total sleep time and the longest sustained sleep period (sleep continuity variables) differed significantly at some of the ages measured. Although overall sleep architecture appears highly resilient and well organized, some indications of sleep fragmentation and shortened nighttime sleep periods were observed in the substance‐exposed infants. More research is needed to explain why sleep‐continuity variables and not sleep‐state proportion variables differed between the two groups.     

Keeping the Body in Mind: The Influence of Body Esteem and Body Boundary Aberration on Consumer Beliefs and Purchase Intentions

This research explores the influence of consumers’ body‐related information on beliefs and purchase intentions toward products for which the consumption experience is significantly and directly determined by body‐related information (e.g., feel, fit, sense of safety) when the products are bought in body‐absent purchase environments such as the Internet. We examine the effects of consumers’ body esteem (i.e., like or dislike of one's body) and body boundary aberration (variation in the perceived location of the edges of one's body) in the context of apparel purchases that are made on the Internet. Body esteem had a positive influence on involvement with apparel, and body boundary aberration had a negative influence on consumers’ overall concern with the fit of apparel. Involvement with apparel and overall concern with fit, in turn, significantly influenced consumers’ intentions to purchase apparel online. Consequently, consumers with high body esteem were less likely to buy on the Internet and those with high body boundary aberration were more likely to buy.

Stress and inflammation among older adults: The moderating role of religiosity

Chronic stress weakens the immune system and leads to heightened bodily inflammation, which in turn is linked with serious health conditions. This study examined whether religiosity moderates the relationship between stress and inflammation (measured by C-reactive Protein (CRP)). A sample of 4,734 community-dwelling older adults was drawn from the 2006 wave of the Health and Retirement Study. Logistic regression was used to analyze the relationship between chronic stress (8-item index), inflammation (high CRP level), and religiosity (organizational, nonorganizational, and intrinsic), controlling for other factors. Higher levels of stress were significantly associated with high inflammation/CRP (p = .039). Further, intrinsic religiosity acted as a moderator of this relationship (p = .024), such that the relationship between stress and inflammation is lessened for persons with higher levels of intrinsic religiosity. Higher intrinsic religiosity attenuated the effects of stress on inflammation, suggesting that individuals with stronger religious commitment/motivation may better cope with stress.
