Child Care Center Staff Readiness to Change in an Early Childhood Obesity Prevention Program.

CONTEXT: The childcare center (CCC) setting has the potential to be a strong foundation that supports the introduction of sustainable healthy lifestyle behaviors to prevent childhood obesity. It is important to assess barriers and facilitators to healthy weight development initiatives via program evaluation, including measuring CCC staff readiness to change. OBJECTIVE: The overall goal of this study was to assess the readiness level over 1 school year among CCC staff who participated in "Healthy Caregivers-Healthy Children" (HC2), a cluster randomized controlled trial that evaluated the effectiveness of a childhood obesity prevention program from 2015 to 2018 in 24 low-income, racially/ethnically diverse centers. A secondary outcome was to assess how a CCC's stage of readiness to change was associated with CCC nutrition and physical activity environment, measured via the Environment and Policy Assessment and Observation (EPAO) tool. DESIGN: Mixed-models analysis with the CCC as the random effect assessed the impact of readiness to change over time on EPAO outcomes. PARTICIPANTS: Eighty-eight CCC teachers and support staff completed the HC2 readiness to change survey in August 2015 and 68 in August 2016. Only teachers and staff randomized to the treatment arm of the trial were included. MAIN OUTCOME: Readiness to change and the EPAO. RESULTS: Results showed the majority of CCC staff in advanced stages of readiness to change at both time points. For every increase in readiness to change stage over 1 year (eg, precontemplation to contemplation), there was a 0.28 increase in EPAO nutrition scores (95% confidence interval [CI], 0.04-0.53; P = .02) and a 0.52 increase in PA score (95% CI, 0.09-0.95; P = .02). CONCLUSIONS: This analysis highlights the importance between CCC staff readiness to change and the CCC environment to support healthy weight development. Future similar efforts can include consistent support for CCC staff who may not be ready for change to support successful outcomes.

Children's injuries in legislated types child-care institutions.

BACKGROUND: Severe injuries in child-care institutions are an important social issue. However, no reports on this matter have been made in Japan. This study examined trends in severe injuries at child-care institutions, including the impact of the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We conducted a serial cross-sectional study and interrupted time-series (ITS) analysis with a linear regression model to assess trends in the incidence rate of severe injuries using Japanese national open data between January or April 2017 and December 2021. Participants were individuals utilizing legislated types child-care institutions. The outcomes were annual and monthly incidence rates of severe injuries in legislated types child-care institutions. RESULTS: The number of legislated types child-care institutions increased from 32,793 facilities in 2017 to 38,666 facilities in 2021, and the number of participants rose from 2,802,228 in 2017 to 3,059,734 in 2021. The annual incidence rate of severe injuries in 2021 was 58.3 cases per 100,000 person-years, which is twofold higher than that in 2017. The ITS for the monthly incidence rate demonstrated an increasing trend before the COVID-19 pandemic. CONCLUSIONS: Before the COVID-19 pandemic, the monthly incidence rate of severe injuries in legislated types child-care institutions increased. The annual incidence rate in Japan may have also increased during the observation period.

Change in Nutrition and Physical Activity Practices in Early Childcare and Education Settings in Illinois During the COVID-19 Pandemic.

CONTEXT: For many young children, early childcare and education (ECE) programs are the only source of nutritious meals and physical activity (PA); however, the COVID-19 pandemic led to program closures, restrictions, and changed practices. OBJECTIVE: To examine changes in nutrition and PA-related best practices in ECE settings in Illinois from 2019, just prior to the pandemic, as compared to 2022. We also examined how changes over time varied by program type (ie, centers vs homes), Child and Adult Care Food Program (CACFP) status, and/or Head Start/Early Head Start status. DESIGN: The study design is a repeated cross-sectional survey administered in December 2019 and October 2022. SETTING: State of Illinois. PARTICIPANTS: A total of 888 and 1162 ECE providers completed initial and follow-up surveys, respectively. INTERVENTION: NA. MAIN OUTCOME MEASURE: Provider report of meeting 14 nutrition and 9 PA-related best practices. RESULTS: Overall, 9 nutrition-related best practices were maintained and 5 declined over time. Centers, CACFP, and Head Start providers reported significant declines in meeting nutrition-related practices over time. A total of 8 PA-related best practices were maintained and 1 declined over time. Centers reported a significant decline in 5 of the PA-related best practices over time, and these declines were significantly different than in homes over time. Similarly, Head Start programs reported a decline in 4 PA-related best practices over time, and the change was significantly different from non-Head Start programs in 3 of the 4 practices. CONCLUSION: The findings of this study should be considered a new baseline for ECE nutrition and PA-related best practices in Illinois and should serve as a wake-up call for advocates nationwide with regard to the provision of nutrition and PA-related best practices in centers and by CACFP and Head Start providers postpandemic.

[Heat and heavy rain prevention measures in daycare centres and care facilities: an evaluation of risk perception, communication and information materials]. / Maßnahmen zur Hitze- und Starkregenvorsorge in Kitas und Pflegeeinrichtungen: Eine Evaluation von Risikowahrnehmung, Kommunikation und Informationsmaterialien.

BACKGROUND AND AIM: Heat and heavy rain can have negative health impacts for people in Germany. Vulnerable groups in particular, such as children and the elderly, are at increased risk and require special precautions. This paper examines how employers of the municipal administration and facilitating organisations perceive the risk of heat and heavy rain for daycare centres and care facilities, and to what extent an exchange takes place between the municipal level and the facilities. In addition, specially developed information materials with recommendations for action for adapting to heat and heavy rain that are aimed at such facilities were evaluated. METHODS: In the summer of 2021, we conducted a quantitative survey. A total of 333 respondents from municipal administrations, facilitating organisations and institutions participated. Descriptive analyses and ANOVAs were conducted. RESULTS: Risk perception and adaptation knowledge concerning heat was perceived higher than concerning heavy rain. The intention to support institutions in finding measures for adaptation was also higher with regard to heat. The majority of interviewees from municipal administrations and institutions communicated with institutions through various channels on different topics including the natural hazards mentioned. The information material was evaluated positively. DISCUSSION: This article shows that facilities are seen as very affected by heat waves. Awareness towards heavy rainfall needs to be raised. The feedback on the information material clearly shows a high need in this area.

Otitis Media With Effusion After the COVID-19 Pandemic: Return to the Past and New Lessons.

OBJECTIVE: To assess the prevalence of otitis media with effusion (OME) among children who attended a tertiary level audiologic center 2 and 3 years after the COVID-19 lockdown, and to determine the impact of temporary interruption of day care center attendance on chronic OME. STUDY DESIGN: Retrospective study. SETTING: Tertiary level referral audiologic center. METHODS: We assessed the prevalence of OME among children aged 6 months to 12 years in 3 different periods (May-June 2022, January-February 2023, and May-June 2023) and compared the results with those of the corresponding periods before the COVID-19 lockdown. We also compared the disease resolution rates between a subgroup of children with chronic OME who interrupted day care center attendance for a 2-month period (Subgroup A) and a similar subgroup who continued attending day care centers (Subgroup B). RESULTS: The prevalence of OME was 38.5% (138/358) in May-June 2022, 51.9% (193/372) in January-February 2023, and 40.9% (149/364) in May-June 2023. No significant prevalence differences were observed between the periods May-June 2019, May-June 2022, and May-June 2023 (P = .78), and between the periods January-February 2020 and January-February 2023 (P = .93). At the May-June 2023 assessment, the children belonging to Subgroup A presented a greater rate of disease resolution (85.7%, 18/21) than the children belonging to Subgroup B (32%, 8/25, P < .001). CONCLUSION: This study suggests that the prevalence of OME has returned to prelockdown levels, and that interrupting day care center attendance for a 2-month period could be effective in resolving most cases of chronic OME.

Identifying elevated child weight from 3 to 24 months: Early transitions into nonparental care and to solid foods.

BACKGROUND: Early entry into nonparental care (NPC) and introduction to solid foods (ITS) have been linked to elevated weight, however, little research exists on the combined influence of these transitions on child weight over time. OBJECTIVES: Identify groups of children based on early NPC and ITS timing and examine whether NPC-ITS groups differentially affect child weight over time. METHOD: Data were drawn from STRONG Kids2 (n = 468). Primary predictors include NPC (by 3M)-ITS (< or ≥6M) groups; outcome variables include child weight-for-length/height z-scores (WFL/WFHz) (3, 12, 18, and 24 months). Multilevel regression was used to examine the NPC-ITS groups as predictors of child WFL/WFHz. RESULTS: Six groups were identified: 27% Parental Care-ITS before 6M, 31% Parental Care-ITS after 6M, 12% Daycare-ITS before 6M, 14% Daycare-ITS after 6M, 10% Kincare-ITS before 6M, and 7% Kincare-ITS after 6M. Children who were in daycare (regardless of ITS) or kincare-ITS before 6M demonstrated the highest WFL/WFHz over time, compared to their parental care counterparts. CONCLUSIONS: NPC-ITS combinations on child WFL/WFHz across the first 2 years of life highlight the need for a partnership approach among parental and nonparental caregivers to support the feeding of infants throughout the transition to solid foods.

Childcare centre attendance and health, growth, and development among children aged 0-3 years in low- and middle-income countries: A systematic review.

Background: Lack of childcare for children aged 0-3 years has emerged as a global crisis, accentuated by women's increasing workforce participation and recognition that young children require nurturing care. Through this systematic review, we sought to examine associations between childcare centre attendance in low- and middle-income countries (LMICs) and children's health, growth, and development, and to generate childcare centre programmatic and research recommendations for children aged 0-3 years. Methods: We systematically searched PsycINFO, MEDLINE, PubMed, and Cochrane for articles on centre-based childcare for children aged 0-3 years in LMICs, published between 2000 and 2021 in English (or which were translated into English). We excluded articles on specialised subgroups or interventions. We imported the retrieved articles into Covidence for review and assessed them for bias using the National Institutes of Health (NIH) quality assessment tool. Results: Twenty-two articles (24 studies) met the inclusion criteria, encompassing 36 927 children from 10 countries across Mexico and South America (n = 12), Africa (n = 5), and Asia (n = 5). Outcomes included health (n = 12), growth/nutrition (n = 6), and development (n = 6). Study quality assessments were low; 41% exceeded 50% of quality criteria and 45% adjusted for confounders. Associations between childcare attendance and outcome measures were primarily negative for health (n/N = 7/12) and positive for growth/nutrition (n/N = 5/6) and development (n/N = 4/6). Childcare centre programmatic recommendations for children aged 0-3 years included: age-specific policies; program quality, including safety, hygiene, nutrition, and curriculum; access and affordability; parent engagement; financial support; and workforce development. Research recommendations included: study design, including enrolment age, frequency, duration, childcare type, home and childcare sociodemographic and cultural environments, child and caregiver outcomes, and analytical approaches; longitudinal studies; and implementation research. Conclusions: Rigorous primary research in global childcare for young children is urgently needed. Policies, programmes, and investments in high-quality childcare can promote nurturing care for young children, enabling mothers to participate in the workforce.

Association of Child Masking With COVID-19-Related Closures in US Childcare Programs.

Importance: It is not known how effective child masking is in childcare settings in preventing the transmission of SARS-CoV-2. This question is critical to inform health policy and safe childcare practices. Objective: To assess the association between masking children 2 years and older and subsequent childcare closure because of COVID-19. Design, Setting, and Participants: A prospective, 1-year, longitudinal electronic survey study of 6654 childcare professionals at home- and center-based childcare programs in all 50 states was conducted at baseline (May 22 to June 8, 2020) and follow-up (May 26 to June 23, 2021). Using a generalized linear model (log-binomial model) with robust SEs, this study evaluated the association between childcare program closure because of a confirmed or suspected COVID-19 case in either children or staff during the study period and child masking in both early adoption (endorsed at baseline) and continued masking (endorsed at baseline and follow-up), while controlling for physical distancing, other risk mitigation strategies, and program and community characteristics. Exposures: Child masking in childcare programs as reported by childcare professionals at baseline and both baseline and follow-up. Main Outcomes and Measures: Childcare program closure because of a suspected or confirmed COVID-19 case in either children or staff as reported in the May 26 to June 23, 2021, end survey. Results: This survey study of 6654 childcare professionals (mean [SD] age, 46.9 [11.3] years; 750 [11.3%] were African American, 57 [0.9%] American Indian/Alaska Native, 158 [2.4%] Asian, 860 [12.9%] Hispanic, 135 [2.0%] multiracial [anyone who selected >1 race on the survey], 18 [0.3%] Native Hawaiian/Pacific Islander, and 5020 [75.4%] White) found that early adoption (baseline) of child masking was associated with a 13% lower risk of childcare program closure because of a COVID-19 case (adjusted relative risk, 0.87; 95% CI, 0.77-0.99), and continued masking for 1 year was associated with a 14% lower risk (adjusted relative risk, 0.86; 95% CI, 0.74-1.00). Conclusions and Relevance: This survey study of childcare professionals suggests that masking young children is associated with fewer childcare program closures, enabling in-person education. This finding has important public health policy implications for families that rely on childcare to sustain employment.

Surveillance of SARS-CoV-2 transmission in educational institutions, August to December 2020, Germany.

This study aims at providing estimates on the transmission risk of SARS-CoV-2 in schools and day-care centres. We calculated secondary attack rates (SARs) using individual-level data from state-wide mandatory notification of index cases in educational institutions, followed by contact tracing and PCR-testing of high-risk contacts. From August to December 2020, every sixth of overall 784 independent index cases was associated with secondary cases in educational institutions. Monitoring of 14 594 institutional high-risk contacts (89% PCR-tested) of 441 index cases during quarantine revealed 196 secondary cases (SAR 1.34%, 0.99-1.78). SARS-CoV-2 infection among high-risk contacts was more likely around teacher-indexes compared to student-/child-indexes (incidence rate ratio (IRR) 3.17, 1.79-5.59), and in day-care centres compared to secondary schools (IRR 3.23, 1.76-5.91), mainly due to clusters around teacher-indexes in day-care containing a higher mean number of secondary cases per index case (142/113 = 1.26) than clusters around student-indexes in schools (82/474 = 0.17). In 2020, SARS-CoV-2 transmission risk in educational settings was low overall, but varied strongly between setting and role of the index case, indicating the chance for targeted intervention. Surveillance of SARS-CoV-2 transmission in educational institutions can powerfully inform public health policy and improve educational justice during the pandemic.

Connecting Families to Food Resources amid the COVID-19 Pandemic: A Cross-Sectional Survey of Early Care and Education Providers in Two U.S. States.

Early care and education (ECE) settings are important avenues for reaching young children and their families with food and nutrition resources, including through the U.S. federally funded Child and Adult Care Food Program (CACFP). Researchers conducted a cross-sectional survey of ECE providers in two U.S. states in November 2020 to identify approaches used to connect families with food and nutrition resources amid the COVID-19 pandemic. Logistic regression models were used to estimate odds of sites reporting no approaches and adjusted Poisson models were used to estimate the incidence rate ratio of the mean number of approaches, comparing sites that participate in CACFP to those that did not. A total of 589 ECE sites provided responses. Of those, 43% (n = 255) participated in CACFP. CACFP participating sites were more likely to report using any approaches to connecting families to food resources and significantly more likely to report offering "grab and go" meals, providing meal delivery, distributing food boxes to families, and recommending community food resources than non-CACFP sites. This study suggests that CACFP sites may have greater capacity to connect families to food resources amid emergencies than non-CACFP participating sites.

Prevalence and Transmission of Severe Acute Respiratory Syndrome Coronavirus Type 2 in Childcare Facilities: A Longitudinal Study.

OBJECTIVE: To evaluate the role of childcare facilities in the transmission of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) in a longitudinal study to gain further knowledge of SARS-CoV-2 prevalence, transmission, and spread among preschool children, their parents, and their caregivers. STUDY DESIGN: Children aged 1-6 years, their parents, and their caregivers in 14 childcare facilities in Dresden, Saxony/Germany were invited to participate in the KiTaCoviDD19-study between July 2020 and January 2021. Seroprevalence of SARS-CoV-2 antibodies was assessed up to 4 times during the study period in all participating adults, and demographic characteristics, as well as epidemiologic information on personal SARS-CoV-2 history were obtained. Samples for stool virus shedding of SARS-CoV-2 were analyzed by polymerase chain reaction every 2-4 weeks in all participating children. RESULTS: In total, 318 children, 299 parents and 233 childcare workers were enrolled. By January 2021, 11% of the participating adults were found to be seropositive, whereas the percentage of children shedding SARS-CoV-2 was 6.8%. Overall, we detected 17 children with SARS-CoV-2 virus shedding in 8 different childcare facilities. In 4 facilities, there were a maximum of 3 connected cases in children. Approximately 50% of SARS-CoV-2 infections in the children could not be connected to a secondary case in our study population. CONCLUSIONS: This study does not provide evidence of relevant asymptomatic ("silent") spread of SARS-CoV-2 in childcare facilities in both low- and high-prevalence settings. Our findings add to the evidence that childcare and educational settings do not have a crucial role in driving the SARS-CoV-2 pandemic.

Childcare Attendance and Academic Achievement at Age 16 Years.

Importance: Low school preparedness is linked to high school dropout, poor employment, and negative outcomes. Childcare attendance may increase school readiness and foster academic achievement. Objective: To explore whether childcare attendance was associated with academic achievement at the end of compulsory schooling (age 16 years in the UK), whether maternal education level was a moderator, and the benefit-cost ratio of childcare regarding productivity returns of academic achievement. Design, Setting, and Participants: In this cohort study, data were included from the Avon Longitudinal Study of Parents and Children (ALSPAC) born from April 1991 to December 1992 and the UK National Pupil Database for examination results. Data on academic achievement at age 16 years were available for 11 843 participants. Data were collected from June 2006 to June 2008, and data were analyzed from September 2019 to May 2020. Exposures: On average, 3.7%, 5.9%, and 90.4% attended childcare full time, part time, and less than 10 hours per week, respectively. Maternal education was assessed by questionnaire during pregnancy. Analyses included weights for population representativeness and propensity score weights to account for parental selection into childcare. Main Outcomes and Measures: Academic achievement was defined as no certificate, Level 1 General Certificate of Secondary Education (GCSE; limited training), or Level 2 GCSE (qualification for academic post-16 education; high school diploma equivalent). Lifetime productivity return estimates were withdrawn from previous economic analysis based on pupil's qualifications. Results: Of 14 541 children in the ALSPAC study, 8936 children had complete data on childcare attendance, academic achievement, and maternal education levels. Of these, 4499 (50.3%) were male. Attending childcare was associated with higher probabilities of obtaining a Level 1 or 2 GCSE qualification (Level 1: relative risk, 1.41; 95% CI, 1.16-1.73; Level 2: relative risk, 1.62; 95% CI, 1.30-2.01); however, this association was moderated by the child's maternal education level. When children of mothers with low education attended childcare, their probability of no GCSE qualification went from 28.9% (95% CI, 26.8-31.0) to 20.3% (95% CI, 18.0-22.8), whereas children of mothers with higher education had a probability of no qualification of less than 10% regardless of childcare attendance. The benefit-cost ratio for each £1 (US $1.40) invested in full-time childcare attendance for children of mothers with low education was £1.71 (95% CI, 1.03-2.45; US $2.39; 95% CI, 1.44-3.43) for those who reached a Level 2 GCSE qualification. Conclusions and Relevance: Promoting universal childcare with facilitated access for children of lower socioeconomic backgrounds deserves to be considered as a way to reduce the intergenerational transmission of low academic achievement.

Characteristics of COVID-19 Cases and Outbreaks at Child Care Facilities - District of Columbia, July-December 2020.

The occurrence of cases of COVID-19 reported by child care facilities among children, teachers, and staff members is correlated with the level of community spread (1,2). To describe characteristics of COVID-19 cases at child care facilities and facility adherence to guidance and recommendations, the District of Columbia (DC) Department of Health (DC Health) and CDC reviewed COVID-19 case reports associated with child care facilities submitted to DC Health and publicly available data from the DC Office of the State Superintendent of Education (OSSE) during July 1-December 31, 2020. Among 469 licensed child care facilities, 112 (23.9%) submitted 269 reports documenting 316 laboratory-confirmed cases and three additional cases identified through DC Health's contact tracers. Outbreaks associated with child care facilities,† defined as two or more laboratory-confirmed and epidemiologically linked cases at a facility within a 14-day period (3), occurred in 27 (5.8%) facilities and accounted for nearly one half (156; 48.9%) of total cases. Among the 319 total cases, 180 (56.4%) were among teachers or staff members. The majority (56.4%) of facilities reported cases to DC Health on the same day that they were notified of a positive test result for SARS-CoV-2, the virus that causes COVID-19, by staff members or parents.§ Facilities were at increased risk for an outbreak if they had been operating for <3 years, if symptomatic persons sought testing ≥3 days after symptom onset, or if persons with asymptomatic COVID-19 were at the facility. The number of outbreaks associated with child care facilities was limited. Continued implementation and maintenance of multiple prevention strategies, including vaccination, masking, physical distancing, cohorting, screening, and reporting, are important to reduce transmission of SARS-CoV-2 in child care facilities and to facilitate a timely public health response to prevent outbreaks.¶.

Model-based projections for COVID-19 outbreak size and student-days lost to closure in Ontario childcare centres and primary schools.

There is a pressing need for evidence-based scrutiny of plans to re-open childcare centres during the COVID-19 pandemic. Here we developed an agent-based model of SARS-CoV-2 transmission within a childcare centre and households. Scenarios varied the student-to-educator ratio (15:2, 8:2, 7:3), family clustering (siblings together versus random assignment) and time spent in class. We also evaluated a primary school setting (with student-educator ratios 30:1, 15:1 and 8:1), including cohorts that alternate weekly. In the childcare centre setting, grouping siblings significantly reduced outbreak size and student-days lost. We identify an intensification cascade specific to classroom outbreaks of respiratory viruses with presymptomatic infection. In both childcare and primary school settings, each doubling of class size from 8 to 15 to 30 more than doubled the outbreak size and student-days lost (increases by factors of 2-5, depending on the scenario. Proposals for childcare and primary school reopening could be enhanced for safety by switching to smaller class sizes and grouping siblings.

The relationship between educators' and children's physical activity and sedentary behaviour in early childhood education and care.

OBJECTIVES: The early childhood education and care (ECEC) environment has a significant role to play in the promotion of physical activity and reduction of sedentary behaviour in young children. Educators may be an important social factor influencing children's physical activity and sedentary behaviour, however limited evidence exists on this relationship. The primary aim was to examine the relationships between educators' and children's physical activity and sedentary behaviours within ECEC settings. DESIGN: A cross sectional study. METHODS: The study involved 11 ECEC centres from NSW, Australia (n=110 educators; n=490 children). Data for each centre were collected over five consecutive days. Objectively measured physical activity and sedentary behaviour were collected from children using Actigraph accelerometers and were analysed using STATA 13c. Linear regression was used to examine relationships between children and educators, adjusted for centre clustering. RESULTS: A significant association was reported between educators' sedentary behaviour and children's sedentary behaviour (p=0.047). Educators spent 61% of their work day in sedentary behaviour. No significant associations were reported between educators' physical activity and children's physical activity, for any intensity of physical activity. CONCLUSIONS: The positive relationship between educators' sedentary behaviours and children's sedentary behaviour in this study highlights a novel area to target in future interventions. Improving physical activity and sedentary behaviours of educators will likely improve children's physical activity levels and thus health and wellbeing outcomes.

Hand-washing promotion for preventing diarrhoea.

BACKGROUND: Diarrhoea accounts for 1.8 million deaths in children in low- and middle-income countries (LMICs). One of the identified strategies to prevent diarrhoea is hand washing. OBJECTIVES: To assess the effects of hand-washing promotion interventions on diarrhoeal episodes in children and adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, nine other databases, the World Health Organization (WHO) International Clinical Trial Registry Platform (ICTRP), and metaRegister of Controlled Trials (mRCT) on 8 January 2020, together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA: Individually-randomized controlled trials (RCTs) and cluster-RCTs that compared the effects of hand-washing interventions on diarrhoea episodes in children and adults with no intervention. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trial eligibility, extracted data, and assessed risks of bias. We stratified the analyses for child day-care centres or schools, community, and hospital-based settings. Where appropriate, we pooled incidence rate ratios (IRRs) using the generic inverse variance method and a random-effects model with a 95% confidence interval (CI). We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS: We included 29 RCTs: 13 trials from child day-care centres or schools in mainly high-income countries (54,471 participants), 15 community-based trials in LMICs (29,347 participants), and one hospital-based trial among people with AIDS in a high-income country (148 participants). All the trials and follow-up assessments were of short-term duration. Hand-washing promotion (education activities, sometimes with provision of soap) at child day-care facilities or schools prevent around one-third of diarrhoea episodes in high-income countries (incidence rate ratio (IRR) 0.70, 95% CI 0.58 to 0.85; 9 trials, 4664 participants, high-certainty evidence) and may prevent a similar proportion in LMICs, but only two trials from urban Egypt and Kenya have evaluated this (IRR 0.66, 95% CI 0.43 to 0.99; 2 trials, 45,380 participants; low-certainty evidence). Only four trials reported measures of behaviour change, and the methods of data collection were susceptible to bias. In one trial from the USA hand-washing behaviour was reported to improve; and in the trial from Kenya that provided free soap, hand washing did not increase, but soap use did (data not pooled; 3 trials, 1845 participants; low-certainty evidence). Hand-washing promotion among communities in LMICs probably prevents around one-quarter of diarrhoea episodes (IRR 0.71, 95% CI 0.62 to 0.81; 9 trials, 15,950 participants; moderate-certainty evidence). However, six of these nine trials were from Asian settings, with only one trial from South America and two trials from sub-Saharan Africa. In seven trials, soap was provided free alongside hand-washing education, and the overall average effect size was larger than in the two trials which did not provide soap (soap provided: RR 0.66, 95% CI 0.58 to 0.75; 7 trials, 12,646 participants; education only: RR 0.84, 95% CI 0.67 to 1.05; 2 trials, 3304 participants). There was increased hand washing at major prompts (before eating or cooking, after visiting the toilet, or cleaning the baby's bottom) and increased compliance with hand-hygiene procedure (behavioural outcome) in the intervention groups compared with the control in community trials (data not pooled: 4 trials, 3591 participants; high-certainty evidence). Hand-washing promotion for the one trial conducted in a hospital among a high-risk population showed significant reduction in mean episodes of diarrhoea (1.68 fewer) in the intervention group (mean difference -1.68, 95% CI -1.93 to -1.43; 1 trial, 148 participants; moderate-certainty evidence). Hand-washing frequency increased to seven times a day in the intervention group versus three times a day in the control arm in this hospital trial (1 trial, 148 participants; moderate-certainty evidence). We found no trials evaluating the effects of hand-washing promotions on diarrhoea-related deaths or cost effectiveness. AUTHORS' CONCLUSIONS: Hand-washing promotion probably reduces diarrhoea episodes in both child day-care centres in high-income countries and among communities living in LMICs by about 30%. The included trials do not provide evidence about the long-term impact of the interventions.

ANTECEDENTES: La diarrea es responsable de 1 800 000 muertes de niños en los países de ingresos bajos y medios (PIBM). Una de las estrategias identificadas para prevenir la diarrea es el lavado de manos. OBJETIVOS: Evaluar los efectos de las intervenciones de promoción del lavado de manos sobre los episodios de diarrea en niños y adultos. MÉTODOS DE BÚSQUEDA: El 8 de enero de 2020 se realizaron búsquedas en CENTRAL, MEDLINE, Embase, en otras nueve bases de datos, la Plataforma de registros internacionales de ensayos clínicos (ICTRP) de la Organización Mundial de la Salud (OMS) y el metaRegister of Controlled Trials (mRCT), además de comprobación de referencias, búsqueda de citas y contacto con los autores de los estudios para identificar estudios adicionales. CRITERIOS DE SELECCIÓN: Ensayos controlados aleatorizados (ECA) individuales y por conglomerados que compararon los efectos de las intervenciones de lavado de manos sobre los episodios de diarrea en niños y adultos, con ninguna intervención. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Dos autores de la revisión, de forma independiente, evaluaron la elegibilidad de los ensayos, extrajeron los datos y evaluaron los riesgos de sesgo. Los análisis se estratificaron por guarderías infantiles o escuelas, comunidad y contextos hospitalarios. Cuando fue conveniente, se agruparon los cocientes de la tasa de incidencia (CTI) según el método de la varianza inversa genérica y un modelo de efectos aleatorios con un intervalo de confianza (IC) del 95%. Se utilizaron los criterios GRADE para evaluar la certeza de la evidencia. RESULTADOS PRINCIPALES: Se incluyeron 29 ECA: 13 ensayos de guarderías infantiles o escuelas en países principalmente de ingresos altos (54 471 participantes), 15 ensayos comunitarios en PIMB (29 347 participantes) y un ensayo hospitalario en pacientes con sida en países de ingresos altos (148 participantes). Todos los ensayos y evaluaciones de seguimiento fueron a corto plazo. La promoción del lavado de manos (actividades educativas, a veces con la provisión de jabón) en las guarderías infantiles o las escuelas previene alrededor de un tercio de los episodios de diarrea en los países de ingresos altos (cociente de tasa de incidencia [CTI] 0,70; IC del 95%: 0,58 a 0,85; nueve ensayos, 4664 participantes, evidencia de certeza alta), y podría prevenir una proporción similar en los PIMB, pero solo dos ensayos en zonas urbanas de Egipto y Kenya lo han evaluado (CTI 0,66; IC del 95%: 0,43 a 0,99; dos ensayos, 45 380 participantes, evidencia de certeza baja). Solo cuatro ensayos informaron sobre medidas de cambio en el comportamiento y los métodos de recopilación de datos fueron susceptibles de sesgo. En un ensayo de los EE.UU. se informó de que el comportamiento de lavado de manos mejoró; y en el ensayo de Kenya que proporcionó jabón gratuito, el lavado de manos no aumentó, pero sí el uso de jabón (datos no agrupados; tres ensayos, 1845 participantes, evidencia de certeza baja). La promoción del lavado de manos entre las comunidades en los PIMB probablemente previene alrededor de una cuarta parte de los episodios de diarrea (CTI 0,71; IC del 95%: 0,62 a 0,81; nueve ensayos, 15 950 participantes, evidencia de calidad moderada). Sin embargo, seis de estos nueve ensayos procedían de entornos asiáticos, y solo hubo un ensayo en América del Sur y dos en el África subsahariana. En siete ensayos, el jabón se suministró gratuitamente junto con la educación para el lavado de manos, y el tamaño del efecto medio general fue mayor que en los dos ensayos que no suministraron jabón (jabón suministrado: RR 0,66; IC del 95%: 0,58 a 0,75; siete ensayos, 12 646 participantes; solo educación: RR 0,84; IC del 95%: 0,67 a 1,05; dos ensayos, 3304 participantes). Hubo un aumento del lavado de manos en los momentos más importantes (antes de comer o cocinar, después de ir al baño o de limpiar el trasero del niño), y un aumento en el cumplimiento del procedimiento de higiene de las manos (resultado conductual) en los grupos de intervención, en comparación el control, en los ensayos comunitarios (datos no agrupados: cuatro ensayos, 3591 participantes; evidencia de certeza alta). La promoción del lavado de manos en el único ensayo realizado en un hospital en una población de alto riesgo mostró una reducción significativa de los episodios medios de diarrea (1,68 menos) en el grupo de intervención (diferencia de medias ­1,68; IC del 95%: ­1,93 a ­1,43; un ensayo, 148 participantes, evidencia de certeza moderada). En este ensayo hospitalario la frecuencia del lavado de manos aumentó hasta siete veces al día en el grupo de intervención versus tres veces al día en el grupo control (un ensayo, 148 participantes, evidencia de certeza moderada). No se encontraron ensayos que evaluaran los efectos de la promoción del lavado de manos sobre las muertes relacionadas con la diarrea ni el coste­efectividad. CONCLUSIONES DE LOS AUTORES: La promoción del lavado de manos probablemente reduce los episodios de diarrea en las guarderías infantiles de los países de altos ingresos y en las comunidades que viven en los PIMB, en aproximadamente el 30%. Los ensayos incluidos no aportan evidencia sobre el efecto a largo plazo de esta intervención.

No SARS-CoV-2 carriage observed in children attending daycare centers during the intial weeks of the epidemic in Belgium.

To gain knowledge about the role of young children attending daycare in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic, a random sample of children (n = 84) aged between 6 and 30 months attending daycare in Belgium was studied shortly after the start of the epidemic (February 29th) and before the lockdown (March 18th) by performing in-house SARS-CoV-2 real-time polymerase chain reaction. No asymptomatic carriage of SARS-CoV-2 was detected, whereas common cold symptoms were common (51.2%). Our study shows that in Belgium, there was no sign of early introduction into daycare centers at the moment children being not yet isolated at home, although the virus was clearly circulating. It is clear that more evidence is needed to understand the actual role of young children in the transmission of SARS-CoV-2 and their infection risk when attending daycare.

Association of environmental factors and high HFMD occurrence in northern Thailand.

BACKGROUND: The major population vulnerable to hand, foot and mouth disease (HFMD) is children aged less than 5 years, particularly those who are cared for at day care centers (DCCs). This study aimed to assess the associations of environmental and sanitation factors with high HFMD occurrence rates in DCCs of northern Thailand. METHODS: A case-control study was used to gather information from caregivers and local government administrative officers. DCCs in areas with high and low HFMD occurrence rates were the settings for this study. A validated questionnaire was used to collect environmental and sanitation information from the DCCs. In-depth interviews were used to collect information from selected participants who were working at DCCs and from local government administrative officers on the HFMD capacity and prevention and control strategies in DCCs. Logistic regression analysis was used to determine the associations between many environmental factors and HFMD at the α = 0.05 significance level while the content analysis was used to extract information from the interviews. RESULTS: Two variables were found to be associated with a high rate of HFMD occurrence: the number of sinks available in restrooms and the DCC size. Children attending DCCs that did not meet the standard in terms of the number of sinks in restrooms had a greater chance of contracting HFMD than children who were attending DCCs that met the standard (AOR = 4.21; 95% CI = 1.13-15.04). Children who were attending a large-sized DCC had a greater chance of contracting HFMD than those attending a small-sized DCC (AOR = 3.28; 95% CI = 1.21-5.18). The yearly budget allocation and the strategies for HFMD control and prevention, including collaborations among stakeholders for HFMD control and prevention in DCCs, were associated with the effectiveness of HFMD control and prevention. CONCLUSIONS: The number of sinks in restrooms and DCC size are major concerns for HFMD outbreaks. Sufficient budget allocation and good collaboration contribute to effective strategies for preventing and controlling HFMD in DCCs.

Abusive Head Trauma in Day Care Centers.

BACKGROUND: Abusive head trauma (AHT) warrants particular attention in terms of prevention. One of the key questions asked is how often AHT occurs in infant day care centers compared with private parental or nonparental homes. To investigate this, we studied the caretaking arrangement and child's location at the time of injury in a cohort of cases involving AHT from the courts. METHODS: This multicenter retrospective study covering an 18-year period included all medical and court records of 323 children (2.5 months to 3 years) with AHT, confirmed by the authors acting as medical experts. All markers for abuse and forensic written reports were analyzed by using a standardized data collection tool. The usual child care arrangement and the child's location at the time of injury were noted. The percentage of day care centers found in the study was compared to the expected rate in the French population (19.5%) by using the χ2 test. RESULTS: In 317 AHT cases (98.5%), the assault occurred in a private home (4 in other indoor settings and 1 with missing data). In only 1 case, shaking occurred in a day care center when the nurse was alone with the infant for a few minutes. In 317 cases (98.5%), the usual child care arrangement was by a single adult in charge of 1 or more children. CONCLUSIONS: The fact that AHT is an unusual occurrence in day care centers could help social service agencies make decisions in terms of prevention. Recent government policies regarding stay-at-home orders during a pandemic have given this issue new relevance.
