Background Asymptomatic SARS-CoV-2 infection in children is highly prevalent but its acute and chronic implications have been minimally described. Methods In this controlled case-ascertained household transmission study, we recruited asymptomatic children <18 years with SARS-CoV-2 nucleic acid testing performed at 12 tertiary care pediatric institutions in Canada and the United States. We attempted to recruit all test-positive children and 1 to 3 test-negative, site-matched controls. After 14 days' follow-up we assessed the clinical (ie, symptomatic) and combined (ie, test-positive, or symptomatic) secondary attack rates (SARs) among household contacts. Additionally, post–COVID-19 condition (PCC) was assessed in SARS-CoV-2–positive participating children after 90 days' follow-up. Results A total of 111 test-positive and 256 SARS-CoV-2 test-negative asymptomatic children were enrolled between January 2021 and April 2022. After 14 days, excluding households with co-primary cases, the clinical SAR among household contacts of SARS-CoV-2–positive and –negative index children was 10.6% (19/179; 95% CI: 6.5%–16.1%) and 2.0% (13/663; 95% CI: 1.0%–3.3%), respectively (relative risk = 5.4; 95% CI: 2.7–10.7). In households with a SARS-CoV-2–positive index child, age <5 years, being pre-symptomatic (ie, developed symptoms after test), and testing positive during Omicron and Delta circulation periods (vs earlier) were associated with increased clinical and combined SARs among household contacts. Among 77 asymptomatic SARS-CoV-2–infected children with 90-day follow-up, 6 (7.8%; 95% CI: 2.9%–16.2%) reported PCC. Conclusions Asymptomatic SARS-CoV-2–infected children, especially those <5 years, are important contributors to household transmission, with 1 in 10 exposed household contacts developing symptomatic illness within 14 days. Asymptomatic SARS-CoV-2–infected children may develop PCC. [ABSTRACT FROM AUTHOR]

This study aimed to examine the association between breastfeeding and childhood obesity. A multinational cross‐sectional study of 4,740 children aged 9–11 years was conducted from 12 countries. Infant breastfeeding was recalled by parents or legal guardians. Height, weight, waist circumference, and body fat were obtained using standardized methods. The overall prevalence of obesity, central obesity, and high body fat were 12.3%, 9.9%, and 8.1%, respectively. After adjustment for maternal age at delivery, body mass index (BMI), highest maternal education, history of gestational diabetes, gestational age, and child's age, sex, birth weight, unhealthy diet pattern scores, moderate‐to‐vigorous physical activity, sleeping, and sedentary time, exclusive breastfeeding was associated with lower odds of obesity (odds ratio [OR] 0.76, 95% confidence interval, CI [0.57, 1.00]) and high body fat (OR 0.60, 95% CI [0.43, 0.84]) compared with exclusive formula feeding. The multivariable‐adjusted ORs based on different breastfeeding durations (none, 1–6, 6–12, and > 12 months) were 1.00, 0.74, 0.70, and 0.60 for obesity (Ptrend =.020) and 1.00, 0.64, 047, and 0.64 for high body fat (Ptrend =.012), respectively. These associations were no longer significant after adjustment for maternal BMI. Breastfeeding may be a protective factor for obesity and high body fat in 9‐ to 11‐year‐old children from 12 countries. [ABSTRACT FROM AUTHOR]

Purpose:To test a model of child, family and service determinants of participation in family and recreational activities for young children with cerebral palsy (CP). Methods:Participants were a convenience sample of 429 children (242 males) with CP, aged 18 to 60 months, representing all levels of the Gross Motor Function Classification System (GMFCS). Children were divided into two groups by GMFCS levels, levels I to II and levels III to V. Data on impairments and gross motor function were collected by therapists; parents provided information about children’s health conditions and adaptive behaviour. Seven months later, parents reported on family life and services received. One year after the beginning of the study, parents reported their children’s participation. Data from the two groups of children were analysed separately using structural equation modelling. Results:The model explained 35% and 40% of the variance of frequency of participation in family and recreation and 28% and 38% of enjoyment in participation, for the two groups of children, respectively. Children’s adaptive behaviour, family ecology, and number of community recreational programs were associated with the frequency of participation for both groups. Gross motor function was only associated with the frequency of participation for children in levels III–V. Adaptive behaviour was associated with enjoyment for both groups. The extent services met children’s needs was associated with enjoyment for children in levels I to II and family ecology was a determinant of enjoyment for children in levels III to V. Conclusion:Supporting children’s adaptive behaviour, family ecology, and access to community recreational programmes may foster participation in family and recreational activities for young children with CP.Implications for RehabilitationParticipation in family and recreational activities for young children with CP is complex and influenced by child, family and environmental factors.Practitioners are encouraged to support children’s adaptive behaviour and access to community programs and family relationships, involvement in community activities and expectations of their children.Optimizing gross motor function for children who have limitations in self-mobility may enhance their participation in family and recreational activities.For children with a good prognosis for walking, providing services perceived by parents to meet their children’s needs may enhance children’s enjoyment of participation.

This study aimed to assess the communicative skills of children and young adults with ring 14 syndrome and linear 14q deletions, investigating the relationships among their language development and their genetic, clinical, psychomotor and behavioural characteristics. Participants were 36 individuals with chromosome 14 aberrations whose parents completed a questionnaire, specifically developed in five languages, to assess their son's/daughter's development. Data analysis showed that chronological age does not account for the high individual variability found in the participants' skills. The comparison between participants with ring 14 syndrome and participants with 14q linear deletions showed that the former were characterised by a higher occurrence of epilepsy, abnormalities of the retina and autism. The participants with smaller amounts of deleted genetic material were those who had a higher level of language development. Because ring 14 syndrome is a rare genetic disease, the collection of data from a large group of individuals could be helpful to create expectations about the possible developmental outcomes of these children.

Background: There is a paucity of research evidence to guide health care providers' practice in pediatric palliative care. At the same time, some clinicians and Institutional Review Boards are reluctant to approve such studies because of concerns about further burdening families. Yet, there is some evidence that research participation can have positive effects for families. Objective: To obtain parents' perceptions about their experience of participating in one of two research studies. Design: Descriptive, quantitative survey. Setting/Subjects: Caregivers of children with life-threatening conditions ( n=323) who were caring for the child at home. Measurements: Researcher-designed Impact of Participation questionnaire. Results: Few differences between the two groups were found on Impact responses. Not a single parent reported regretting participating in their study and almost all (96.3%) reported that conducting research about family's experiences in pediatric palliative care had value. Just over three-quarters (76.2%) did not find participation at all painful, and 73.7% reported that participation was about as painful as expected, with 23.2% reporting less painful. Approximately half (50.5%) said that participation had at least some positive effect and only three parents reported any negative effect. An overwhelming majority (93.4%) would recommend participation to other parents in a similar situation. Conclusions: Participation in research for families with children who have a life-threatening condition is not only acceptable to parents, but may in fact have a positive effect. Although clinicians and Institutional Review Boards may be hesitant to fully support such research, it is clear that conducting research in the field of pediatric palliative care is important.
