The Effects of Acute Sleep Restriction on Inhibitory Control and Self-Regulation in 2-Year-Old Children

Introduction: Poor sleep health in early childhood is known to negatively affect behavioral self-regulation, which is linked to reduced school readiness and poor later life outcomes. The aim of this study was to understand the role of sleep loss in behavioral self-regulation strategies and inhibitory control using a standard task (Forbidden Toy) that measures a child’s capacity to delay gratification. Compared to a day when toddlers had a daytime nap, it was hypothesized that after acute nap deprivation they would have a shorter latency to touching the toy and would resort to more immature, maladaptive self-regulation strategies to delay gratification. Methods:In this experimental, counterbalanced study, 25 healthy children (11 males, 34.1 ± 2.3 months-old)followed an sleep stabilization schedule for ≥5 days prior to a baseline (nap) and one day of acute nap deprivation condition (no-nap). Inhibitory control was assessed using an age-appropriate, attractive toy. Children were left alone with the toy for a 3-minute waiting period and videotaped. The videos were coded for latency to touch and 11 discrete self-regulation strategies. McNemar repeated measures Chi-Squared tests were used to compare between conditions: 1) the number of children who touched the toy and 2) the number of children who employed each of the strategies. Paired t-tests (one-tailed) were used to compared the latencies to touch and the percentage of time each strategy was employed between conditions. Results:There was no difference between the baseline and sleep restriction conditions in the number of children who touched the toy (X-squared= 0, p = 0.50) and or their mean latency to touch (t = 0.27, p = 0.393). Of the 11 strategies coded, no significant differences were found in the number of children who used each of the strategies or the percent time the children spent using each strategy: visual inspection (t = 0.35, p = 0.37); self-soothing (t = 0.62, p = 0.27); talk about task rules (t = -1.32, p = 0.10); irrelevant speech (t = -0.04, p = 0.49); unintelligible speech (t = 0.16, p = 0.44); fidgeting (t = 0.38, p = 0.35); removing self (t = 1.03, p = 0.16); physical restraint (t = 1.64, p = 0.06); passive waiting (t = 0.80, p = 0.22); object distraction (t = -1.17, p = 0.13); and social bids (t = -0.03, p = 0.49). Discussion:These findings indicate that acute nap deprivation in toddlerhood may not have an immediate impact on inhibitory control and self-regulation strategies. This is inconsistent with other findings reported in the field, and limitations in the task administration and contextual factors (e.g. socio-economic status) may contribute to the conflicting results. Through early childhood, there are striking developmental changes in behavior and control, and at 30-36 months of age, children may not have sufficient cognitive and emotional resources to exert inhibitory control and self-regulate. Future research should examine developmental changes in the effects of acute sleep restriction on inhibitory control and self-regulation strategies as children progress through the early childhood years

A qualitative study on the impact of long-distance travel for gynecologic cancer care

Background: Women with gynecologic malignancies experience improved clinical outcomes when they are treated by gynecologic oncologists and in high-volume cancer centers. However, geography is a major barrier to high-volume care for patients. This qualitative study was undertaken to identify facilitators and barriers to patients traveling long distances for gynecologic cancer care. Methods: Semi-structured interviews were conducted with 19 women with gynecologic malignancies traveling \u3e50 miles for treatment at Wake Forest Comprehensive Cancer Center. Eight interviews included caregivers. Four interview domains focused on personal challenges and coping strategies related to accessing cancer care. Results: Mean distance traveled for care was 87 miles (range: 54-218). Most participants reported that recommendations from physicians, friends, and family motivated travel. 10/19 participants were aware of closer sites for cancer care; 5 had unfavorable experiences elsewhere. Barriers to travel included time, cost, childcare, difficulty navigating, and physical discomfort. Social support was an important facilitator of travel for care; some patients utilized loaned money or vehicles. Participants reported significant energy expenditure scheduling travel, coordinating time off work, and arranging overnight stays near the cancer center. Suggestions for care improvement included travel vouchers, transportation assistance, signage and personnel to help with navigation, and appointments later in the day. Participants supported in-person oncologist outreach to rural areas and appointments via telemedicine; few preferred the current infrastructure. Conclusion: Patients who travel long distances for gynecologic cancer care encounter significant burdens and rely heavily on social and financial support. Interventions should be developed and evaluated to reduce the burden of long-distance travel and develop efficient methods of outreach, including telemedicine

Explaining racial and ethnic inequalities in postpartum allostatic load: Results from a multisite study of low to middle income woment

AbstractBackgroundRacial and ethnic inequalities in women's health are widely documented, but not for the postpartum period, and few studies examine whether neighborhood, psychosocial, and biological factors explain these gaps in women's health.MethodsUsing prospective longitudinal data collected from 1766 low to middle income women between 2008 and 2012 by the Community Child Health Network (CCHN), we tested the extent to which adjustment for neighborhood, economic, psychological, and medical conditions following a birth explained differences between African American, Latina, and White women in an indicator of physiological dysregulation allostatic load (AL), at one year postpartum as measured by 10 biomarkers: Body Mass Index, Waist Hip Ratio, systolic and diastolic blood pressure, high sensitivity C-reactive protein, Hemoglobin A1c, high-density lipoprotein and cholesterol ratio, and diurnal cortisol.ResultsMean postpartum AL scores were 4.65 for African American, 4.57 for Latina and 3.86 for White women. Unadjusted regression estimates for high AL for African American women (with White as the reference) were 0.80 (SD = 0.11) and 0.53 (SD = 0.15) for Latina women. Adjustment for household poverty, neighborhood, stress, and resilience variables resulted in a reduction of 36% of the excess risk in high AL for African Americans versus Whites and 42% of the excess risk for Latinas compared to Whites.ConclusionsRacial and ethnic inequalities in AL were accounted for largely by household poverty with additional contributions by psychological, economic, neighbourhood and medical variables. There remained a significant inequality between African American, and Latina women as compared to Whites even after adjustment for this set of variables. Future research into health inequalities among women should include a fuller consideration of the social determinants of health including employment, housing and prepregnancy medical conditions

Preconception Maternal Posttraumatic Stress and Child Negative Affectivity: Prospectively Evaluating the Intergenerational Impact of Trauma

The developmental origins of psychopathology begin before birth and perhaps even prior to conception. Understanding the intergenerational transmission of psychopathological risk is critical to identify sensitive windows for prevention and early intervention. Prior research demonstrates that maternal trauma history, typically assessed retrospectively, has adverse consequences for child socioemotional development. However, very few prospective studies of preconception trauma exist, and the role of preconception symptoms of posttraumatic stress disorder (PTSD) remains unknown. The current study prospectively evaluates whether maternal preconception PTSD symptoms predict early childhood negative affectivity, a key dimension of temperament and predictor of later psychopathology. One hundred and eighteen women were recruited following a birth and prior to conception of the study child and were followed until the study child was 3–5 years old. Higher maternal PTSD symptoms prior to conception predicted greater child negative affectivity, adjusting for concurrent maternal depressive symptoms and sociodemographic covariates. In exploratory analyses, we found that neither maternal prenatal nor postpartum depressive symptoms or perceived stress mediated this association. These findings add to a limited prospective literature, highlighting the importance of assessing the mental health of women prior to conception and providing interventions that can disrupt the intergenerational sequelae of trauma

Surrogate utility estimation by long-term partners and unfamiliar dyads

To what extent are people able to make predictions about other people's preferences and values? We report two experiments that present a novel method assessing some of the basic processes in surrogate decision-making, namely surrogate-utility estimation. In each experiment participants formed dyads who were asked to assign utilities to health related items and commodity items, and to predict their partner's utility judgments for the same items. In experiment one we showed that older adults in long-term relationships were able to accurately predict their partner's wishes. In experiment two we showed that younger adults who were relatively unfamiliar with one another were also able to predict other people's wishes. Crucially we demonstrated that these judgments were accurate even after partialling out each participant's own preferences indicating that in order to make surrogate utility estimations people engage in perspective-taking rather than simple anchoring and adjustment, suggesting that utility estimation is not the cause of inaccuracy in surrogate decision-making. The data and implications are discussed with respect to theories of surrogate decision-making

Risk, resilience, and depressive symptoms in low-income African American fathers.

OBJECTIVE: Parental depression influences family health but research on low-income African American fathers is limited. The primary goal of the present study was to examine the role of paternal risk factors and resilience resources in predicting depressive symptoms in the year after birth of a child in a sample of African American fathers. We hypothesized that paternal risk factors (low socioeconomic status [SES], perceived stress, negative life events, racism, avoidant coping style) and resources (social support, self-esteem, collective efficacy, approach-oriented coping style) would predict depressive symptoms in fathers at 1 year postbirth controlling for depressive symptoms at 1 month postbirth. METHOD: African American fathers (n = 296) of predominantly low SES from 5 U.S. regions were interviewed at 1 and 12 months after birth of a child regarding potential risk factors, resilience resources, and depressive symptoms. RESULTS: Depressive symptoms were low on average. However, hierarchical linear regression analyses revealed that avoidant coping style and experiences of racism predicted more depressive symptoms in fathers nearly a year after the birth of a child controlling for symptoms at 1 month. CONCLUSIONS: How fathers cope with stress and common everyday experiences of racism contributed to depressive symptoms in the year following birth of a child. Interventions that target race-related stressors and decrease avoidant coping may promote better outcomes in this important and understudied population. (PsycINFO Database Recor

A post-trial survey to assess the impact of dissemination of results and unmasking on participants in a 13-year randomised controlled trial on age-related cataract

<p>Abstract</p> <p>Background</p> <p>The Italian-American Clinical Trial of Nutritional Supplements and Age-Related Cataract was designed to assess the impact of a multivitamin-mineral supplement on age-related cataract. Trial results showed evidence of a beneficial effect of the supplement on all types of cataract combined, opposite effects on two of the three types of cataract (beneficial for nuclear opacities and harmful for posterior sub-capsular opacities) and no statistically significant effect on cortical opacities. No treatment recommendations were made. A post-trial survey was conducted on 817 surviving elderly participants to assess their satisfaction, their understanding of treatment assignment to supplement or placebo and the success of masking.</p> <p>Methods</p> <p>Trial results were communicated by letter and the level of satisfaction and of understanding of the results was assessed by a questionnaire. Participants were offered the option of being unmasked: a second questionnaire was administered to this subset to assess their understanding of the randomisation process and the success of masking.</p> <p>Results</p> <p>610 participants (74.7%) responded to the survey:</p> <p>94.6% thought the description of the results was "very clear" or "quite clear", 5.4% "not clear" or "do not know"; 89.8% considered the results "very interesting" or "quite interesting", 10.2% "not interesting" or "do not know"; 60.3% expressed "satisfaction", 17.2% "both satisfaction and concern", 2.6% "concern", 19.9% "indifference" or "do not know".</p> <p>480 participants (78.7%) accepted the offer to be unmasked to their treatment assignment: 395 (82.3%) recalled/understood the possibility of assignment to vitamins or placebo, 85 (17.7%) did not. 68 participants (17.2%) thought they had taken vitamins (79.4% were correct; p = 0.0006), 47 (11.9%) thought they had taken placebo (59.6% were correct; p = 0.46) and 280 (70.9%) declared they did not know.</p> <p>Conclusions</p> <p>The results were made difficult to explain to study participants by the qualitatively different effect of treatment on the two most visually significant types of cataract. Although the study did not lead to a recommendation to use the dietary supplement, the vast majority of participants reported satisfaction after they received the results but almost 20% of the participants expressed some concern. Masking to treatment assignment was successful in the majority of participants.</p
