We investigated the development of the end-state comfort effect in young children. Fifty-one children from three age-groups (3, 4, and 5 years old) participated in the study. They performed the dowel placing task, which required them to reach for a horizontal dowel and to insert one of its ends into a target disk. Depending on which end was instructed, end-state comfort could be reached by picking up the dowel either with an overhand or with an underhand grip. All children reached for the dowel with an overhand grasp when this resulted in a comfortable end-state (i.e., thumb-up posture). A different pattern emerged when an underhand grip had to be selected. Here, 18% of the 3-year-olds, 45% of the 4-year-olds, and 67% of the 5-year-olds used an underhand grip and finished the action comfortably. For the first time, these results show a distinct pattern of gradual improvement in children’s sensitivity to reach end-state comfort across three age-groups.

Original Thinking

A sample of 188 children in three age groups, preschool, first and third grades, were administered the Patterns Task of the Multidimensional Stimulus Fluency Measure in four test conditions. The conditions systematically varied dimension (three or two) and presentation mode (handling or nonhandling). The fluency measure assessed ideational fluency, popular and original responses, as a measure of creative potential in young children. Analysis showed that dimensionality does not play a major role in the generation of original responses for any grade. However, handling 3-dimensional or 2-dimensional stimuli did appear to facilitate original thinking in preschool children. The use of 2-dimensional photographs which depict dimensionality appeared to compensate for the need to have 3-dimensional stimuli.

The purpose of the article is to study the development of family structure in Finland in 1960—1987. For the first time, the data provide total coverage of all family types. Cohabitation became increasingly common in the 1970s but has so far not been covered by the data of official family statistics. Further, sample data have only included family data on selected age groups. Statistics Finland has now developed a method by which family and cohabitation data may automatically be derived from information about people’s place of residence, demographic characteristics, and relatives. The family statistics data for 1981 and 1987 have been reproduced. The article describes changes in the numbers of families of different types, families with young children and families of different sizes, as well as developments in the regional family structure during the 1960—1987 period. In addition, developments in the prevalence of living in a family and living in a family with young children are studied with reference to the 1981—1987 period.

Abstract. In a contingency learning task, 4-year-old and 8-year-old children had to predict the outcome displayed on the back of a card on the basis of cues presented on the front. The task was embedded in either a causal or a merely predictive scenario. Within this task, either a forward blocking or a backward blocking procedure was implemented. Blocking occurred in the causal but not in the predictive scenario. Moreover, blocking was affected by the scenario to the same extent in both age groups. The pattern of results was similar for forward and backward blocking. These results suggest that even young children are sensitive to the causal structure of a contingency learning task and that the occurrence of blocking in such a task defies an explanation in terms of associative learning theory.

BACKGROUND The increasing screen time exposure among young children in general and the reported negative consequences associated with excessive ST, calls for focused strategies to reduce ST, especially among young children. OBJECTIVE This systematic review aimed to identify effective parental intervention strategies to reduce ST among preschool children. METHODS A total of five databases, namely Cochrane Central Register of Controlled Trials, CINAHL, Medline Complete, PubMed, and Scopus, were searched for randomised controlled trials that involved intervention strategies in ST reduction among preschool children. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines were used. RESULTS A total of nine studies were assessed. The results showed that besides providing knowledge and awareness regarding ST, having restrictive practices, offering alternative activities to parents, and removal of screen from child’s bedroom were the most common strategies used by studies that reported successful intervention. Intervention duration of between six to eight weeks was sufficient to produce ST reduction. Face-to-face method was the commonest mode of delivery. Theoretical constructs that aimed at increasing parental self-efficacy, listing outcome expectations, and offering reinforcement of strategies that targeted both the parents and home environment were beneficial in reducing ST. CONCLUSIONS By offering appropriate strategies to parents, a reduction in the amount of ST was observed among the children. Future intervention studies could benefit in exploring culturally adapted strategies, especially in developing countries. Trials of higher quality would also facilitate the drawing of conclusions in future research. CLINICALTRIAL PROSPERO No: CRD42020199398

Argumentation is an important aspect in the field of education because of its impact on learning processes. At the same time, argumentation is a complex activity in terms of cognitive, relational, emotional and social dynamics. In this paper, I investigate and I describe possible difficulties encountered by children during the argumentative process. The study involves 25 preschool children at a kindergarten engaged in three building tasks. The tasks were video-recorded and the argumentative discussions transcribed. For the aim of this paper, I analyze how argumentation are distributed among participants. I select interactions in which participants apparently do not argue or there are differences in the degree of argumentative participation between participants of the same group. I analyze these interactions and moments of impasse in the argumentative steps. The findings show how the simplicity of solving the task (e.g., when children do not encounter any problem in completing the activity) and the children’s self-perception of their competences in solving the task may have an impact on argumentation activities. Moreover, this perception is co-constructed by children within the interaction. The study contributes to the line of research on designing argumentation and highlights the role of the adult in managing children’s interactions.

Background: Rwanda’s commitment to reducing malnutrition is evident in their multisectoral nutrition policy and wide array of nutrition partners. However, the prevalence of micronutrient deficiencies and the suitability of current strategies to address existing deficiencies is unclear. Objective: To review the available evidence related to the prevalence of micronutrient deficiencies across the life cycle and strategies in place to address them. Methods: We reviewed scientific and grey literature on nutritional problems in Rwanda, emphasizing micronutrient deficiencies and anemia, and current strategies to address micronutrient malnutrition. Results: Overall, there is scant evidence related to the types and prevalence of micronutrient deficiencies among populations across the life cycle in Rwanda. Existing evidence is primarily limited to outdated or small regional surveys focusing on iron or vitamin A among women and young children. Surveys have assessed the prevalence of anemia and indicate that anemia is very high among young children and moderately high among other age-groups. However, there are limited data on the context-specific causes of anemia in Rwanda across population groups. Current nutrition strategies mainly target women and young children and are primarily designed to reduce vitamin A deficiency and/or anemia caused by micronutrient deficiencies. Conclusions: Rwanda has many nutrition programs in place that address micronutrient deficiencies in young children and a few for women of reproductive age. However, gaps exist in knowledge of the extent of different types of micronutrient deficiencies among all populations across the life cycle and whether the delivery of nutrients through current programs is meeting actual needs.

Abstract Background Differences in clinical presentation and viral loads according to age in young children with RSV, and their correlation with disease severity are poorly defined. The aim of this study was to define age-dependent the differences in demographic, clinical factors and viral loads between children < 2 years of age with mild RSV infection evaluated as outpatients versus those hospitalized with severe RSV infection. Figure 1. Sign and Symptoms according to disease severity and age in infants with RSV infection. Most relevant signs and symptoms were stratified in outpatients (orange) vs inpatients (blue) by age in (A) < 3 months, (B) between 3 and 6 months, and (C) > 6 to 24 months of age. The Y axis represents the signs and symptoms in the two disease severity groups and the X axis the frequency of that specific symptom (%). Numbers next to bars represent the exact number of patients with that specific sign/symptom. Comparisons by Fisher exact test. Symbol (*) indicate significant 2-sided p values Figure 2. Viral load differences according to age in infants with RSV infection. The Y axis represents RSV loads in log10 copies/mL and the X axis differences in viral loads in outpatients (orange) and inpatients (blue) in the three age groups. Comparisons by Mann Whitney test. Methods Previously healthy children < 2 years old with mild (outpatients) and severe (inpatients) RSV infection were enrolled and nasopharyngeal swabs were obtained for RSV typing and quantitation by real-time PCR. Patients were stratified by age (0-< 3, 3-6, and >6-24 months) and multivariable analyses were performed to identify clinical and viral factors associated with severe disease. Results From 2014-2018 we enrolled 534 children with RSV infection: 130 outpatients and 404 inpatients. Median duration of illness was 4 days for both groups, yet viral loads were higher in outpatients than inpatient in the three age groups (Fig 1). Wheezing was more frequent in outpatients of older age (>3 months) than in inpatients (p< 0.01), while fever was more common in inpatients that outpatients (p< 0.01) and increased with age (Fig 2). Adjusted analyses confirmed that increased work of breathing and fever were consistently associated with hospitalization irrespective of age, while wheezing in infants >3 months, and higher RSV loads in children >6-24 months were independently associated with reduced disease severity. Conclusion Age had a significant impact defining the interactions among viral loads, specific clinical manifestations and disease severity in children with RSV infection. These observations highlight the importance of patient stratification when evaluating interventions against RSV.

Although Ablepharus kitaibelii and its subspecies are wide-spread, being distributed from the Carpathian Basin through the Balkans to Iraq, their habitat and environmental niche is poorly known. Ablepharus kitaibelii fitzingeri is almost entirely limited to the Carpathian Basin, and is amongst the most strictly protected and least known reptiles of Central and Eastern Europe. The main aim of our study was to determine habitat use preferences of different age groups of A. kitaibelii fitzingeri and Lacerta viridis. The occurrence of green lizard was determined by the abundance of refugia rather than by the naturalness of grasslands. The snake-eyed skink prefers semi-natural grasslands with abundant tussock-forming grass or sedge species, avoiding densely shrubby places. For the first time, we show that woodland mosaics lacking shrubs and temporary grasslands next to forest edges are important for the species. Microhabitat use by snake-eyed skink varies with age group; adults preferring shady edge zones rich in leaf litter and shadier grassland spots provided by woodland mosaics, whereas juveniles were found in natural, more open grasslands far from forest edges and in woodland mosaics with dense shrubby understory. Our results contribute to a better understanding of the ecological needs of A. kitaibelii fitzingeri. Our methodology could be adapted to other species and subspecies of Ablepharus. Based on our results, it is important to reconsider habitat management activities, which should not be limited to shrub control: the main goal should be the development of a diverse habitat structure.

Comparing motor assessment tools that are available for young children is important in order to select the most appropriate clinical and research tools. Hence, this study compared motor performance assessed with the Zurich Neuromotor Assessment-2 (ZNA-2) to the Movement Assessment Battery for Children-2 (MABC-2). The sample consisted of 169 children, aged 3–5 years (87 boys; 51%). We used Pearson correlations to examine relationships between the ZNA-2 and MABC-2 component and total scores. In addition, Pearson correlations were performed between individual fine motor and balance items of the ZNA-2 and MABC-2. Results were that the total scores of the ZNA-2 and MABC-2 correlated moderately ( r = .40, p < .001). Non-significant to moderate correlations were found between components ( r = −.00 to .47) and between individual items of fine motor skills ( r = .04 to .38) and balance ( r = −.12 to .38). Thus, the ZNA-2 and MABC-2 measure partly similar and partly different aspects of motor performance.

Mandatory Vaccination

Согласно данным ВОЗ, современные эпидемиологические исследования показали, что рецидивирующие респираторные инфекции у детей раннего и дошкольного возраста сохраняются на высоком уровне 10-50% в течение более 40 лет. Конец вакцинации может спровоцировать массовые инфекционные заболевания. Врачи бьют тревогу, что число отказников от обязательной вакцинации растет. Только в каждой поликлинике Алматы 30-40 родителей в год говорят о готовности к профилактике заболеваний. Среди тех, кто категорически отказывается трогать своих детей иголками, - те, кто идет по пути религии. Они считают, что прививка противоречит убеждениям. В последнее время список недовольных групп пополняют и простые жители, которые скептически относятся к квалификации белых. According to WHO, current epidemiological studies have shown that recurrent respiratory infections in young children and preschool children persist at a high level of 10-50% for more than 40 years. The end of vaccination can provoke mass infectious diseases. Doctors are sounding the alarm that the number of refusers from mandatory vaccination is growing. Only in every polyclinic in Almaty, 30-40 parents a year talk about their readiness for disease prevention. Among those who categorically refuse to touch their children with needles are those who follow the path of religion. They believe that vaccination is contrary to their beliefs. Recently, the list of discontented groups has been supplemented by ordinary residents who are skeptical about the qualifications of whites.
