Youth secrets are associated with poorer sleep and asthma symptoms via negative affect.

OBJECTIVE: Among older children and adolescents, keeping secrets from parents is consistently associated with lower levels of psychological well-being. Further, concealing one's thoughts and emotions has been associated with poor physical health outcomes in adults. However, it remains an open question whether secret-keeping is associated with poorer health and health-related behaviors (such as sleep) among youth and, if those hypothesized links exist, what the psychological mechanisms might be. We investigated the associations among youth secrecy towards parents, daily asthma symptoms and daily sleep behaviors in a sample of low-income youth with asthma aged 10-17 and tested negative affect as a possible mediator of these associations. METHODS: One hundred and seventy two youths reported the extent to which they kept secrets towards parents over a period of four days. Asthma symptoms, nighttime awakenings, sleep onset latency, and subjective sleep quality were assessed with daily diaries completed by youths. RESULTS: More frequent secret-keeping was associated with more severe asthma symptoms, lower ratings of sleep quality and greater number of nighttime awakenings. Secrecy was also associated with increased negative affect, which accounted for the associations between secrecy and number of awakenings and daytime asthma symptoms. These findings remained significant after controlling for youth age and other relevant demographic factors. CONCLUSIONS: Our findings suggest that secrecy towards parents can have consequential health outcomes for youth with asthma and point to the importance of investigating affective processes as mediators of the influence of secret-keeping on youth health.

Neighborhood Stress, Depressive Symptoms, and Asthma Morbidity in Youth.

OBJECTIVE: Living in a dangerous and disadvantaged neighborhood is consistently linked with poor health outcomes; however, few studies have investigated psychosocial mechanisms of this relationship. We hypothesized that a specific facet of depression-anhedonia-would partially explain the relationship between stressful neighborhoods and poor health in youth with asthma. METHOD: 156 youths provided reports on their depressive symptoms, daily asthma symptoms, and peak expiratory flow rate (PEFR). Caregivers provided reports on neighborhood characteristics. RESULTS: Youth residing in more at-risk neighborhoods experienced more symptoms of depression, greater asthma symptoms (both during the day and night), and marginally lower PEFR. Indirect effect analyses revealed that the relationship between neighborhood stress and youth asthma symptoms was partially explained by a key symptom of depression, anhedonia. CONCLUSIONS: These findings suggest that the neighborhood-health link is partially explained by symptoms of depression tapping into difficulties experiencing pleasure and motivation.

Youth reports of parents' romantic relationship quality: Links to physical health.

OBJECTIVE: Prior work has shown that negative aspects (e.g., conflict) of marriage or marriage-like relationships are associated with poor health of offspring, but much less is known about the effects of positive aspects (e.g., affection) of parental romantic relationships. This study investigated links between conflict and affection within parents' romantic relationships and the health of youth with asthma. METHOD: Eighty youths with asthma aged 10-17 answered daily questions over a 4-day period about conflict and affection within their parents' romantic relationship, as well as their own daily mood, asthma symptoms, and expiratory peak flow. RESULTS: Multiple regression analyses revealed that romantic affection-but not conflict-was directly associated with higher expiratory peak flow. Further, there was a significant indirect effect of romantic affection via youth positive affect on lower asthma symptoms. CONCLUSION: These results are the first to our knowledge to demonstrate that youth-reported positive characteristics of parents' romantic relationships are associated with better health among youth with asthma.

Asthma-Related Immune Responses in Youth With Asthma: Associations With Maternal Responsiveness and Expressions of Positive and Negative Affect in Daily Life.

OBJECTIVES: Stressful family environments early in life have negative effects on physical health. However, less is known about the health effects of positive aspects of families. We examined the associations between maternal responsiveness and immune markers among youth with asthma and identified youth expressions of positive affect as a potential mechanism of these associations. METHODS: Forty-three youths with asthma (26 boys; aged 10-17 years) wore the Electronically Activated Recorder for 4 days to assess maternal responsiveness and youth expressions of affect from audio-recordings of daily life. Trained coders rated Electronically Activated Recorder sound files for expressions of maternal responsiveness and affect displayed by the youth. Peripheral blood mononuclear cells were isolated, cultured, and assayed to determine stimulated levels of interleukin (IL)-5, IL-13, and interferon-γ. RESULTS: Greater maternal responsiveness was associated with decreased stimulated production of IL-5 (r = -0.38, p = .012) and IL-13 (r = -0.33, p = .031). Greater total positive affect in youth was linked to decreased stimulated production of IL-5 (r = -0.46, p = .002) and IL-13 (r = -0.37, p = .014). Total negative affect among youth was unrelated to immune responses. There was a significant indirect effect of maternal responsiveness via positive affect in youth on lower levels of IL-5 (95% confidence interval = -3.41 to -0.03) and IL-13 (95% confidence interval = -2.34 to -0.01) when adjusting for caregiver-youth conflict and negative affect among youth. CONCLUSIONS: These results indicate the importance of positive family interactions for youth and provide preliminary evidence for a mechanism through which parenting can influence immune responses in youth with asthma.

Naturalistically observed conflict and youth asthma symptoms.

OBJECTIVE: To investigate the links between naturalistically observed conflict, self-reported caregiver-youth conflict, and youth asthma symptoms. METHOD: Fifty-four youth with asthma (age range: 10-17 years) wore the Electronically Activated Recorder (EAR) for a 4-day period to assess interpersonal conflict and caregiver-youth conflict as they occur in daily life. Conflict also was assessed with baseline self-report questionnaires and daily diaries completed by youth participants and their caregivers. Asthma symptoms were assessed using daily diaries, baseline self-reports, and wheezing, as coded from the EAR. RESULTS: EAR-observed measures of conflict were strongly associated with self-reported asthma symptoms (both baseline and daily diaries) and wheezing coded from the EAR. Further, when entered together in regression analyses, youth daily reports of negative caregiver-youth interactions and EAR-observed conflict uniquely predicted asthma symptoms; only EAR-observed conflict was associated with EAR-observed wheezing. CONCLUSION: These findings demonstrate the potential impact of daily conflict on youth asthma symptoms and the importance of assessing conflict as it occurs in everyday life. More broadly, they point to the importance of formulating a clear picture of family interactions outside of the lab, which is essential for understanding how family relationships "get under the skin" to affect youth health.

Effects of socioeconomic status on maternal and child positive behaviors in daily life among youth with asthma.

OBJECTIVE: Socioeconomic disadvantage is associated with poorer behavioral and emotional outcomes in children with asthma. This study investigated the associations between maternal income and education and naturalistically observed behaviors and affect during everyday parent-child interactions. METHODS: 53 predominantly low-income youth with asthma, aged 10-17 years, wore a naturalistic event-sampling device, the Electronically Activated Recorder, for 4 days to assess mother and child positive behaviors and affect in daily life. RESULTS: Maternal education, but not income, was positively associated with child positive behaviors, displays of mother and child positive affect, and increased maternal responsiveness. Maternal positive affect and maternal responsiveness mediated the effect of maternal education on child positive affect. CONCLUSIONS: Our findings suggest that maternal education has an important influence on the socioemotional adjustment of youth with asthma and point to the importance of investigating the independent influence of socioeconomic status components on everyday parent-child interactions.
