Family asthma management and physical activity among urban children.

INTRODUCTION: Urban, low-income, and Black and Latino children with asthma experience higher morbidity and poorer outcomes compared to their suburban, higher-income, and non-Latino White counterparts. This risk is further compounded by higher rates of co-occurring overweight or obesity. Physical activity contributes to both asthma and overweight/obesity status, however, little is known about factors that may promote/limit physical activity among youth from low-income, urban, and racial/ethnic backgrounds. This study evaluates associations between asthma management behaviors and physical activity among a sample of racially/ethnically diverse youth with asthma of both healthy weight and overweight/obesity status. METHOD: 147 children with asthma (Mage = 8.3; 50% overweight/obese status, 58% Hispanic/Latino, and 26% Black) and their families completed the Family Asthma Management System Scale (FAMSS; McQuaid et al., 2005) between 2013 and 2015. Physical activity was measured with waist-worn accelerometers. Differences in FAMSS scores by physical activity levels and associations between FAMSS scores and physical activity for the total sample and by race/ethnicity and weight status were evaluated. RESULTS: Children who met recommended physical activity guidelines had higher FAMSS "medication adherence", t(89) = -2.04, p < .05, and "collaboration with health care provider", t(89) = -2.09, p < .05. More optimal "environmental control" related to lower levels of physical activity (ß = -.21, p < .05) while more optimal "medication adherence" was associated with higher levels of physical activity (ß = .21, p < .05). Differences in these associations were identified by race/ethnicity, though not weight status. CONCLUSIONS: Asthma management behaviors were associated with physical activity, with notable differences by race/ethnicity. Tailored interventions simultaneously addressing multiple health behaviors may be warranted. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Adolescent girls' cardiovascular responses to peer rejection: exploring the impact of early life stress.

Detrimental effects of early life stress on cardiovascular health are evident in adolescence. Cardiovascular reactivity and recovery in response to interpersonal stress may be a mechanism. This study aimed to evaluate if adolescent girls with higher early life stress demonstrated greater cardiovascular reactivity and slower recovery to peer rejection. A sample of 92 adolescent girls (age: M = 13.24) self-reported early life stressors. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were continuously measured before, during, and after a laboratory peer rejection paradigm. Counter to hypotheses, adolescent girls with higher early life stress had lower, not higher, HR during the recovery period. Early life stress was not associated with SBP or DBP recovery. Additionally, early life stress was not associated with SBP, DBP, or HR reactivity. Future research is needed to assess if blunted cardiovascular reactivity to interpersonal rejection during adolescence is a mechanism linking early life stress and later cardiovascular disease risk in women.

Physical Activity Among Urban Children with Asthma: Does Sleep Matter?

The present study examined associations between sleep and physical activity among a diverse sample of 97 urban children (ages 7-9) with persistent asthma. Differences in associations were evaluated by race/ethnicity and weight status. The extent to which sleep moderated the association between lung function and physical activity was also evaluated. Generalized linear models were utilized to examine associations. Findings indicated that, among the aggregate sample, more frequent nighttime awakenings were associated with less time spent engaging in moderate-to-vigorous physical activity (MVPA). Important differences in these associations were identified by both race/ethnicity and weight status. Better lung function was associated with, (a) higher levels of MVPA for children with better sleep efficiency and fewer nighttime awakenings, and (b) lower levels of MVPA for children with poorer sleep efficiency and more frequent nighttime awakenings. In short, sleep mattered with respect to children's physical activity levels in this sample.

Reciprocal Links Between Physical Health and Coping Among Adolescents With Cystic Fibrosis.

OBJECTIVE: Adolescents with cystic fibrosis (CF) often face a unique set of difficulties and challenges as they transition to adulthood and autonomy while also managing a progressive illness with a heavy treatment burden. Coping styles have been related to changes in physical health among youth with chronic illness more generally, but the directionality of these links has not been fully elucidated. Therefore, the objective of this study was to evaluate bidirectional links between coping styles and physical health indicators among adolescents with CF over time. METHODS: Adolescents (N = 79, 54% female) recruited from inpatient and outpatient CF clinics at two sites completed questionnaires assessing secular and religious/spiritual coping styles at two time points (18 months apart, on average). Health indicators including pulmonary functioning, nutritional status, and days hospitalized were obtained from medical records. RESULTS: More frequent hospitalizations predicted lower levels of adaptive secular coping over time. However, poorer pulmonary functioning predicted higher levels of positive religious/spiritual coping. The number of days hospitalized was related to adaptive secular coping and negative religious/spiritual coping. CONCLUSIONS: Among youth with CF, physical health functioning is more consistent in predicting coping strategies than the reverse. Poorer pulmonary functioning appears to enhance adaptive coping over time, suggesting resilience of adolescents with CF, while more frequent hospitalizations may inhibit the use of adaptive coping strategies. Findings support the use of interventions aimed at promoting healthy coping among hospitalized adolescents with CF.

Coping, Attributions, and Health Functioning Among Adolescents with Chronic Illness and Their Parents: Reciprocal Relations Over Time.

The purpose of the study was to identify bidirectional and longitudinal links between attributions, coping, and health functioning among adolescents with chronic illness and their parents. Religious/spiritual coping, attributional styles, and health functioning were assessed among adolescents with chronic illness at two time points approximately 21 months apart. Parental coping and attributions at both time points were also measured. Longitudinal links between variables were tested using an autoregressive cross-lagged path model; adolescent age and disease differences were evaluated via multigroup modeling. Poorer adolescent health functioning at baseline predicted higher use of parent optimistic attributional style at follow-up. Adolescent optimistic attributional style at baseline predicted more positive and less negative religious/spiritual coping at follow-up; adolescent negative religious/spiritual coping at baseline predicted more positive religious/spiritual coping at follow-up. Parent optimistic attributional style and positive religious/spiritual coping at baseline predicted the same constructs among adolescents at follow-up. With respect to age differences, parental negative religious/spiritual coping at baseline was associated with poorer health functioning among younger, but not older, adolescents at follow-up. There were no disease differences in the model. Important links were identified in this family-based model of coping, attributions, and health functioning. The results highlight specific targets for interventions to improve health functioning and coping among adolescents with chronic illness, including parental religious/spiritual coping and adolescent attributional style.

Maternal Sleep Quality and Diurnal Cortisol Regulation Over Pregnancy.

Poor sleep in pregnancy is related to adverse neonatal health. Elevated maternal cortisol has been proposed as a pathway, yet the association in pregnancy is not well understood. The goals of the current study were to examine associations between (a) sleep and cortisol, (b) sleep, cortisol, and neonatal outcomes, and (c) variables that could explain these associations. Two hundred pregnant women completed the Pittsburgh Sleep Quality Index (PSQI; Buysse, Reynolds, Monk, Berman, & Kupfer, 1989) and provided diurnal salivary cortisol samples at two times over pregnancy. Poor sleep quality was associated with greater evening cortisol concentrations at 36 weeks' gestation. This association was mediated by anxiety symptoms. Higher evening cortisol at 36 weeks' gestation was associated with shorter gestation.

Sex differences in biological response to peer rejection and performance challenge across development: A pilot study.

A pilot study of sex differences in biological response to peer rejection and performance challenges across development was conducted. Participants were 59 typically-developing children (ages 8-17; 58% girls); 59 children completed one challenge: 37 completed both challenges. Following a habituation session, participants completed peer rejection (exclusion challenges) and/or performance (speech, arithmetic, tracing) stress sessions. Saliva cortisol and alpha amylase (AA) were measured throughout. Post-pubertal girls showed increased AA and equivalent cortisol output in response to rejection vs. performance; pre-pubertal girls showed heightened cortisol and AA response to performance vs. rejection. Boys showed similar biological responses across puberty, with pre- and post-pubertal boys demonstrating heightened cortisol, but equivalent AA output in response to performance vs. rejection stressors. Although results are preliminary, they suggest increases in relative sensitivity to rejection vs. performance stressors and malleability of stress response across development in girls, but stability of stress response across development in boys. Future, larger-scale, longitudinal studies are needed.

Secretory IgA reactivity to social threat in youth: Relations with HPA, ANS, and behavior.

Although the role of immune marker secretory immunoglobulin A (SIgA) in stress-related health outcomes is gaining recognition, SIgA responsiveness to acute stress has rarely been assessed in adults, and not at all in children. This study was designed to clarify developmental origins of differential immune function-related health risks by investigating youth SIgA responses to psychosocial stressors, including both normative responses and variability related to behavioral problems. Children and adolescents from a larger study (n=82) gave 6 saliva samples during a laboratory session in which they were exposed to a series of performance or interpersonal stressors. Samples were assayed for SIgA, as well as cortisol (representing hypothalamic-pituitary-adrenal axis activity) and alpha-amylase (sAA; representing autonomic nervous system activity). Behavioral problems were assessed with parent-report measures of youth internalizing and externalizing. Youth SIgA trajectories followed a normative pattern of reactivity and recovery around the stressors; however, these responses were blunted in youth with higher externalizing scores. SIgA showed differential associations with cortisol and sAA, and with positive and negative affect; whereas overall levels of SIgA related to cortisol output and positive affect, changes in SIgA over time synchronized with changes in sAA and negative affect. In contrast to SIgA, neither cortisol nor sAA related significantly to behavioral problems. Implications for the role of SIgA during psychosocial stress in the development of immune function-related health risks are discussed.

Primary renal angiosarcoma: a rare malignancy. A case report and review of the literature.

Angiosarcoma is a rare malignant tumor occurring in less than 2% of soft tissue sarcomas. Angiosarcoma involving the kidney usually represents metastasis from skin or visceral primary lesions, while angiosarcoma primarily occurring in the kidney is a very rare neoplasm. In the English literature, from 1942 to the present, only 19 cases of primary kidney angiosarcoma have been reported. A case of primary renal angiosarcoma presenting as a large kidney mass and flank pain occurring after traumatism is reported. The present case represents further evidence of a rare malignancy.
