Objectives: We aimed to assess the test-retest reliability, internal consistency, and validity of the Korean version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT). Methods: The Korean version of the Q-CHAT and the Korean version of the Child Behavior Checklist (CBCL) 1.5-5 were completed by parents of 24 toddlers and preschoolers with autism spectrum disorder (ASD) and 80 unselected toddlers and preschoolers. Parents of the ASD group also completed the Social Communication Questionnaire (SCQ), and Childhood Autism Rating Scale (CARS) scores were obtained from medical records. Results: The ASD group scored higher on the Q-CHAT than the unselected group. The Cronbach's alpha coefficient of the Q-CHAT was 0.658, and test-retest reliability was calculated to be 0.836. The estimated area under the curve was 0.793. The total scores of the Q-CHAT in the ASD group demonstrated significant positive correlations with findings regarding pervasive development problems in the CBCL, SCQ, and CARS. A total score of 33.5 may be a useful cutoff point to use when identifying toddlers at risk of ASD. Conclusion: The Korean version of the Q-CHAT has good reliability and validity and can be used as a screening tool in order to identify toddlers and preschool children at risk of ASD.

Purpose: Injury is a leading cause of morbidity and mortality for children. As an injury prevention measure, the differences in external causes of severe pediatric injuries based on ICECI were analyzed according to age groups. Methods: A retrospective study was performed for pediatric patients under 15 years of age, who had been admitted to the emergency department with severe injuries from January 1998 to December 2004. The external causes of injury were investigated according to the ICECI: intent, mechanisms, places of occurrence, objects/substances producing injury, and related activities. The patients were divided into four groups based on age: infant (<0 year), toddler (1~4 years), preschool age (5~8 years), and school age (9~15 years). Results: The injury mechanisms, the places of occurrence and the related objects/substances vary with the age groups. The most common subtype of traffic accidents was pedestrian injury in pre-school age group. Falls most frequently occurred in the toddler group. But falls from a height of less than l meter height (6 patients) occurred only in the infant group. The most common place of occurrence in the infant group was the home, and that of other groups was the road. The related objects/substances for falls, for example, household furnitures and playground equipment depended on the age group. Conclusion: The age-group specific characteristics of severe pediatric injury were analyzed successfully through the ICECI. Therefore, when establishing a plan for the prevention of pediatric injury, consideration must be given to the differences in the external causes of injuries according to age group.

The purpose of this study is to establish family life cycle of farm and to analyze changes of economic conditions-income, consumption expenditures, savings, assets, and debts-in farm household according to the family life cycle. Income, consumption expenditures, savings, assets, and debts functions are also estimated by age of household head. The data of Farm Household Economy Survey which was conducted in 1983 by Ministry of Agriculture and Fisheries is used in this study. Among total data of 2000, 1603 are analyzed for mean, percentage, and regression using CRISP Program at Office of Rural Development. The results of study can be summarized as follows; 1) Eight stages of family life cycle of farm are established according to the growth of the first child. They are: Establishment stage, Child bearing and preschool stage, Elementary school stage, Middle and high school stage, College and vocational adjustment stage, Period of children's marriage, Re-adjustment stage, and isorganizing stage. 2) The economic conditions of farm household are significantly fluctuated by family life cycle. Among the eight stages, stage Ⅱ is considered relatively comfortable living period and stage Ⅲ, Ⅳ are the most difficult periods of farm household economy. 3) The estimated functions of income, consumption expenditures, savings, assets, and debts by age of household head are as follows; Y(income) = 2, 354, 832+98,456T-1,036T2(F=11.746) C(consumption expenditures) = 81,876+154,976T-1,552T2 (F=37.272) S(savings) = 2,272,956+56,511T+516T2(F=4.262) D(debts) = 903,929+28,300T-438T2(F=3.339) A(assets) = 200,816+1,213,336T-12,930T2(F=21.069) To carry on a reasonable farm household management, a suitable measure to cope with the desire of family and the economic conditions of farm household should be prepared.

This study investigated the relationship between preschoolers' smart media usage in regards to cognitive and language development, especially the mediating effect of preschoolers' smart media addiction tendency and the moderated mediating effect of maternal guidance on smart media usage. The study surveyed 273 preschoolers' mothers who lived in Daegu City and Kyungpook Province. The findings of this study were as follows. First, preschoolers' smart media addiction tendency mediated the relationship between smart media usage time in regards to cognitive and language development. Second, maternal active mediation and monitoring moderated the relationship between preschoolers' smart media usage time and smart media addiction tendency. Third, there was a maternal co-use moderated the mediating effect of preschoolers' smart media addiction tendency on language development. In conclusion, preschoolers' smart media addition tendency mediated the effect of smart media usage time on cognitive and language development. Among the mediation pathways, the influence of preschoolers' smart media addiction tendency on language development was moderated by maternal co-use. The findings of this study suggest that maternal guidance should be applied differently depending on preschoolers' smart media addiction tendency. This study examined preschoolers' and maternal smart media-related variables on preschoolers' cognitive and language development in order to provide preliminary data that can be used to explore the maternal guidance on how to use smart media for their preschool children.

This study examines the effects of health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture and provides data for enhancing the quality of their lives. The sample included 218 consenting subjects who understood the purpose of the study. These subjects resided in three cities in Jeollanam-do, Korea, and were grandmothers entrusted by their adult children with a considerable amount of nurturing for their preschool-aged grandchildren under the age of six. First, the subjects scored an average of 3.05 for health-promoting behaviors and 2.42 for entrapment. Second, the entrapment measurement based on general characteristics showed a higher level of entrapment for those with better health, a lower education level, no religion, male grandchildren to nurture, and unsatisfactory compensation. Third, health-promoting behaviors and entrapment (r=-.304) were negatively correlated. Fourth, the analysis results for effects of health-promoting behaviors of grandmothers on entrapment based on general characteristics of grandmothers as a control variable reveal a significant effect of health-promoting behaviors on entrapment. In other words, the greater the employment of health-promoting behaviors, the less likely the entrapment was to be perceived. Fifth, the results for effects of subcriteria for health-promoting behaviors on entrapment reveal a decrease in entrapment when the subjects engaged in an appropriate level of physical activity with a relaxed state of mind. These results suggest that health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture are likely to influence entrapment and thus that grandmothers should make efforts to actively engage in health-promoting behaviors to reduce any maladaptive effects on nurturing. Social support and related programs should be fostered to enable grandmothers to better practice health-promoting behaviors while nurturing their grandchildren.

This study tried to develop and suggest the program for the family friendly culture in Healthy Families Center. This study focused on specially the cooking program on which entire family member can participate. To develop the program two theoretical perspectives were applied : 1. healthy families perspectives and family leisure, 2. child development perspectives. In the process for developing the program the related literatures were investigated and the proceding cases were analized. The developed program consisted of 4 parts : 1. today, I(child) am the chef, 2. today, daddy(or mommy) is the chef, 3. for my parents and for my kids, 4. let's take a familytrip with snacks. This program is to be made suitable for the families with child(ren) in school age. We suggested various strategies for the effective management the program in Healthy Families Center such as the program manual and workbook, the time duration of program, three steps(introduction-performance-closing) of each session and using the professionals. We suggested the pilot performance of this program for the confirmation the effectiveness of the program. The evaluation index can be used before and after the program implementation. Further research needs to investigate the program for another family life cycle, such as the family with the child(ren) of preschool age or youth child(ren). In addition, for the enhancement of professionals quality who lead the program in field the professionals academy or education program need to be offered.

The purpose of this study is to investigate the moderating effects of language abilities associated with between emotionality, attention deficit hyperactivity disorder (ADHD) and peer play interactions. Two hundred fifty-two participants were 3 year olds, with 136 boys and 116 girls. They were recruited from day care centers and preschools in Gyunggi province and Incheon city. Peer play interaction was assessed by the Penn Interactive Peer Play Scale (PIPPS). Emotionality was measured by Child Behavior Questionnaire (CBQ). ADHD was assessed by teacher ratings of ADHD syndrome. Language abilities were measured by Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI). Teachers completed questionnaires to assess peer play interactions, emotionality, ADHD. The results revealed that language abilities moderated relationships between emotionality and play in isolation. The magnitude of associations between emotionality and play in isolation was greater for high levels of language abilities. Moreover, there were moderating effects of language abilities associated between ADHD and play disruptions. Although ADHD was significantly associated with play disruptions, the association was stronger at the higher levels than the low levels of language abilities. It can be deduced that language abilities of 3 year old children affects the protection factor between emotionality and peer play isolation; whilst, it affects the risk factor on peer play disruptions and ADHD propensity.

BACKGROUND/OBJECTIVES: The aim of this study was to analyze specific foods influencing absolute nutrient intake and between-person variations of nutrient intake among Korean preschoolers. SUBJECTS/METHODS: This study included 2,766 participants aged 1-5 years in the 2009-2013 Korea National Health and Nutrition Examination Surveys. Dietary data were obtained from a 24-h dietary recall method. Major food sources of absolute nutrient intake were evaluated based on percent contribution of each food. To assess the contribution of specific foods to between-person variations in nutrient intake, stepwise multiple regressions were performed and cumulative $R^2$ was used. RESULTS: White rice and milk were main food sources of energy, protein, carbohydrate, phosphorus, iron, potassium, thiamin, riboflavin, and niacin. The percentage of fat contributed by milk was 21.3% which was the highest, followed by pork, soybean oil, and egg. White rice accounted for 25% and 40% of total variability in total energy and carbohydrate intakes, respectively. About 39% of variation in calcium intake was explained by milk while 40% of variation in phosphorous intake was explained by cheese. The top 10 foods contributing to between-person variations in nutrient intakes were similar with food items that mainly contributed to absolute nutrient intakes. The number of foods explaining 90% of absolute amounts of nutrient intakes varied from 28 for vitamin A to 80 for iron. CONCLUSIONS: This study identified specific foods that contributed to absolute nutrient intakes and between-person variations in nutrient intakes among Korean preschoolers. Our findings can be used to develop dietary assessment tools and establish food-based dietary guidelines for young children.

BACKGROUND/OBJECTIVES: Although a lot of effort has been put into increasing fruit and vegetable intakes in preschool children, vegetable intake in this group is still low. This study investigated whether nutrition education focusing on fruit and vegetable intakes can affect preschoolers' fruit and vegetable intakes as well as their behavioral outcomes. SUBJECTS/METHODS: Thirty-five preschoolers (54.3% boys, n = 19) aged 4-6 years residing in Seoul underwent weekly nutrition education intervention (8 sessions) between May and July 2016. Intakes of fruits and vegetables were measured during pre and post-intervention. At snack time, fresh fruit (150 g) and vegetable (120 g) snacks were distributed to each child by teachers. The remaining portions of the snacks were weighed and recorded for each child. Behavioral outcomes were measured by applying Child behavior checklist 1.5-5 and the Diagnostic and statistical manual of mental disorders. RESULTS: During post intervention, vegetable intake increased from $36.15{\pm}30.64g$ to $48.01{\pm}31.23g$ (P = 0.010). Among the emotional and behavioral problems measured by parents, levels of total problems (P = 0.001), internalizing (P = 0.004), externalizing (P = 0.003), anxiety and depression (P = 0.001), and aggressive behavior (P = 0.005) decreased. Anxiety (P = 0.026) score, as measured by teachers, also decreased. CONCLUSIONS: Nutrition education of preschoolers regarding the intakes of fruits and vegetables had a positive effect on preschoolers' vegetable intake as well as on their emotional and behavioral outcomes. A long-term, large-scale study with a broader study design is warranted to further investigate the role of fruit and vegetable intake in cognitive development and behavior of preschoolers.

Head louse infestation is a significant public health problem across the world, particularly among preschool and primary schoolchildren. This study investigated the trends of head louse infestation in the Republic of Korea over a 9-year period (2011-2019), targeting primary schoolchildren in 3 areas of Seoul, 4 other large cities, and 9 provinces. A survey was administered annually by the health staff of each regional office (n= 16) of the Korea Association of Health Promotion (KAHP). The branch offices of KAHP examined a total of 51,508 primary schoolchildren, comprising 26,532 boys and 24,976 girls. Over the 9-year survey, a total of 1,107 (2.1%) schoolchildren tested positive for adults and/or nits of Pediculus humanus capitis. The prevalence was 2.8% (133/4,727) in 2011-2012 and gradually decreased to 0.8% (49/6,461) in 2019 (P< 0.05). Head lice were found more frequently in girls (3.0%; 746/24,976) than in boys (1.4%; 361/26,532) (P< 0.05). In terms of geographic localities, the highest infestation rate, 4.7% (average prevalence over 9 years), was observed in southern Seoul (Gangnam branch of KAHP), whereas the lowest infestation rate, 0.7%, was seen in Gyeongsang (north and south provinces) and western Seoul. Although the prevalence decreased significantly during the 9-year period, head louse infestation remains a health and hygiene issue among primary schoolchildren in the Republic of Korea. Regular surveys along with health education are needed to further improve children's hair hygiene.
