Parental support for physical activity and children's physical activities: a cross-sectional study.

BACKGROUND: Physical activity (PA) in school-aged children is imperative for physical and mental development. However, there has been reduced PA among children in recent years owing to environmental changes, resulting in declining physical strength and athletic ability. Although parents' and children's PA has been found to be correlated, the specific parental caregiving attitudes associated with children's actual levels of PA during school-age years remain unknown. Therefore, this study aimed to examine the relationship between parental support for PA and children's levels of PA. METHODS: In 2017, a self-reported questionnaire survey was administered to 1,515 third-grade students (8-9 years old) and their caregivers in Nagoya, Aichi, a major metropolitan area in Japan. The main items surveyed included the attitudes of children and parents towards PA and the children's actual PA level. Multiple regression analysis was conducted with parental involvement related to PA as the explanatory variable and children's PA as the objective variable. RESULTS: In total, 717 children with valid responses were included in the analysis. The mean age of the children was 9.08 ± 0.33 years; 366 (51.0%) were boys, and 351 (49.0%) were girls. For moderate-to-vigorous and vigorous PA, PA levels tended to be significantly higher in children whose parents provided logistic support such as enrolling their children in a sports club. However, for moderate PA and walking, PA levels tended to be significantly higher in children whose parents used community resources. Modeling and limiting sedentary activities were not associated with children's PA. CONCLUSIONS: The results of this study suggest that direct parental assistance for PA such as logistic support encourages children to engage in moderate-to-vigorous PA; in addition, parental use of community resources may encourage children to engage in moderate and light PA such as walking. Conversely, indirect and negative involvement such as modeling and limiting sedentary activities were not associated with children's PA. Therefore, logistic support may need to be strengthened to encourage moderate-to-vigorous and vigorous PA, which is important for children's health.

Association between sleep habits and behavioral problems in early adolescence: a descriptive study.

BACKGROUND: Sleep habits are related to children's behavior, emotions, and cognitive functioning. A strong relationship exists between sleep habits and behavioral problems. However, precisely which sleep habits are associated with behavioral problems remains unclear. Therefore, the purpose of this study is to clarify the relationship between sleep habits and behavioral problems in early adolescence. METHODS: This study used data from a larger longitudinal research, specifically, data from the year 2021. First-year junior high school students (12-14 years) in Japan were surveyed; their parents (N = 1288) completed a parent-report questionnaire. The main survey items were subject attributes, the Pittsburgh Sleep Quality Index (PSQI), and the Strength and Difficulties Questionnaire (SDQ). RESULTS: Of the 652 valid responses received, 604 individuals who met the eligibility criteria (no developmental disability in the child and completion of all survey items) were included in the analysis. To examine the relationship between sleep habits and behavioral problems, logistic regression analysis using the inverse weighted method with propensity score was conducted with sleep habits (sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep difficulty, use of sleeping pills, difficulty waking during the day, and sleep disturbances) as explanatory variables and behavioral problems (overall difficulty in SDQ) as objective variables. The propensity score was calculated by employing the logistic regression using the inverse weighted method based on propensity scores. Propensity scores were calculated based on gender, family structure, household income, and parental educational background. The results showed that behavioral problems tended to be significantly higher in the group at risk for sleep quality, sleep difficulties, daytime arousal difficulties, and sleep disturbances than in the group with no risk. CONCLUSION: The results suggest that deterioration in sleep quality, sleep difficulties, daytime arousal difficulties, and sleep disturbances may increase the risk of behavioral problems in adolescents.

Experience of annual events in the family and social adjustment of school-age children.

BACKGROUND: Parent-child relationships, the rearing attitudes of parents toward their children as well as the interactive relationships, such as play and cultural activities that parents and children enjoy together, serve as important factors in predicting a child's growth and development. These experiences of annual events celebrated with the family may be related to the school-age child's development. However, this relationship has not been investigated sufficiently. Therefore, this study aimed to identify the relationship between the experience of annual events observed in the family and a child's social adjustment. METHODS: In 2019, a self-administered questionnaire survey targeting fifth graders (ages 10-11) in Japan was conducted with children's parents. Major survey items included participants' characteristics (child's sex, family composition, siblings, household income, and parents' educational backgrounds), annual events observed in the family (Setsubun or the day before the start of spring, Mother's Day, Father's Day, the Tanabata or Weaver Festival, Respect for the Aged Day, Winter solstice, etc.), and the child's social adjustment (Strengths and Difficulties Questionnaire). A total of 653 children who met the criteria of not having any developmental disorders were included as participants for the analysis. RESULTS: The participants had celebrated an average of 15.47 (± 5.52) annual events with their families that year. The number of annual events celebrated was significantly related to family composition and the parents' educational backgrounds. We found that children who came from families with numerous experiences of annual events were more likely to have higher prosocial behavior and were less likely to have externalizing or internalizing problems. The same pattern was found even after adjusting for the family's socioeconomic background and other factors; that is, children who came from families having diverse experiences of annual events were more likely to show prosocial tendencies. CONCLUSIONS: Our findings suggest that the experience of annual events observed with family potentially enhances a child's prosocial behavior. Thus, celebrating and preserving cultural and personal events in the amily context may be an important developmental experience in terms of children's social adjustment.

Changes in Kihon Checklist items and new Certification of long-term care needs among Japanese community-dwelling elders.

Objective: Physical frailty has been considered a risk factor for certification of long-term care needs (hereafter referred to as Certification) under Japan's long-term care insurance (LTCI). Therefore, assessment of frailty in elders should be studied from multiple perspectives. The Kihon Checklist (KCL) is widely used to identify need for support/care among Japanese older adults. This study aims to examine the relationship between changes in KCL items and Certification among Japan's young-old and old-old. Material and Methods: The KCL responses of 7,092 participants were assessed in April 2012 and March 2016, along with gender, age, and living environment. Deaths, Certifications, and relocations were tracked until March 2018. Changes in KCL items were categorized as bad, worse, improved, or good. Results: Between March 2016 and March 2018, about 7.3% of respondents obtained Certifications. KCL item changes increased the risk of new Certification for bad and worse groups, while improved cognitive function among the old-old possibly reduced the risk of new Certification. Conclusion: Therefore, rather than administering the KCL once, identifying KCL changes among people at risk could help prevent or delay their need for long-term care.

Maternal Work-Life Balance and Children's Social Adjustment: The Mediating Role of Perceived Stress and Parenting Practices.

The participation of women with young children in the Japanese labor force has increased dramatically in recent years, bringing growing potential for conflict between work and family roles amid inadequate social systems, such as childcare support. Thus, work-life balance (WLB) of mothers may influence their children's mental health and lifestyle. This study aims to clarify the relationship between parents' WLB and children's mental health, as well as the underlying factors of parental stress and nurturing attitude. The study is based on a questionnaire survey administered in 2019 to fifth-grade elementary school students and their caregivers in Aichi Prefecture, Japan. The regression results indicated that the higher the work-family negative spillover, the higher the child's externalizing and internalizing problems, and the higher the positive spillover, the lower the problems and the higher the prosocial behaviors. Path analysis indicates that maternal WLB is negatively and positively related to children's behavior through maternal stress and parenting practices. The study suggests that maternal WLB is related to children's emotional and behavioral problems. WLB may impact children's emotional and behavioral problems through parents' mental health and involvement with their children, particularly because of work arrangements changing with the COVID-19 pandemic.

The Relationship between Neighborhood Environment and Child Mental Health in Japanese Elementary School Students.

Limited research has examined the relationship between neighborhood environment and mental health outcomes in elementary school students (middle childhood). In countries with high relative poverty, little is known about how neighborhood conditions are related to children's health after controlling for family socioeconomic status; thus, it is necessary to distinguish the particular neighborhood characteristics relevant to behavioral risk in children, independent of socioeconomic position. Using a self-report survey completed by parents, we assessed neighborhood environment characteristics, children's behavioral outcomes, and family socioeconomic status in fourth grade students from Nagoya, in Aichi prefecture, Japan (n = 695). A multiple linear regression was conducted to evaluate to what extent neighborhood characteristics predict child behaviors, after adjusting for socioeconomic variables. Greater aesthetic quality, walkability, accessibility of healthy foods, safety, and social cohesion were inversely linked to children's behavioral problems and positively linked to social competence, suggesting that quality of living environment may affect behavioral outcomes in children, even after controlling for socioeconomic factors. Developing a quality environment that matches these characteristics may minimize the negative impact of a family's socioeconomic distress and is likely to aid socioeconomically disadvantaged parents and their children. Thus, policies and programs that enhance the neighborhood environment for socioeconomically disadvantaged families should be promoted.

What lifestyles are risk factors for low well-being of healthy elderlies dwelled in a local city in super-aging Japan? -Kizugawa cohort study.

The purpose of this cohort study is to clarify the risk factors of low well-being of elderly people who residing in a local city of a super-aging country, Japan. Subjects are people, who have selected randomly from healthy elderly people resided in Kizugawa City, Kyoto Prefecture, in 2010, followed until 2015. Question survey was conducted in both year, and questionnaire consisted of items such as basic attributes, lifestyles (health practices, consultation behaviors, social activities and so on) and well-being (WHO-5). In analysis we made multi-logistic regression analysis using lifestyle variables as an independent variable and well-being as a dependent variable. The results were as follows. 1. Risk factors were not to exercise, knowledge of appropriate diet, subjective feeling of stress for at least a month, not to participate in voluntary activities, age and bad subjective feeling of health. 2. Risk factors in regard to changes of lifestyles using good-good lifestyles as a reference were sustainment of having no time for hobby or relaxation, sustainment or deterioration of subject feeling of stress for at least a month, sustainment or deterioration of having no time for relaxation and deterioration of having no activities with pleasure or aim. A factor promoting well-being is to have more frequencies for going out home. This study shows that in a longevity society it is important for community-dwelling elderly Japanese to have good health practices, appropriate consultation behaviors and good social activities for the purpose of keeping good well-being, and that these results are contributed to health promotion policy for community-dwelling elderly people.

Exposure to marital conflict: Gender differences in internalizing and externalizing problems among children.

PURPOSE: Marital conflict is integral to children's psychosocial well-being. Extant research has shown that the effects of marital conflict on children are likely to vary by gender, indicating that gender plays a significant and complex role in the relationship between marital conflict and child adjustment. Focusing on gender, this study investigates the link between specific marital conflict tactics and children's mental health symptoms in families in which the parents live together. METHODS: This study gathered data from 799 children and their parents in Japan by means of a questionnaire focusing on marital conflict and child behavioral problems. Marital conflict (verbal aggression, physical aggression, stonewalling, avoidance-capitulation, child involvement, and cooperation) was assessed using a Conflict and Problem-Solving Scale. Children's behavioral problems (externalizing and internalizing symptoms) were assessed using the Strengths and Difficulties Questionnaire. RESULTS: The findings highlight the significant impact of specific interparental conflict on children's behavioral problems, demonstrating that there are differences according to the child's gender. More specifically, multivariate analyses targeting boys revealed that cooperation was significantly inversely associated with externalizing problems and internalizing problems, while avoidance-capitulation and verbal aggression were significantly positively associated with externalizing problems. In contrast, multivariate analyses targeting girls revealed that cooperation was significantly inversely associated with externalizing problems and internalizing problems, while avoidance-capitulation and stonewalling were significantly positively associated with internalizing problems. CONCLUSION: This study reveals that interparental conflict is associated with children's behavioral problems. Constructive marital conflict was significantly inversely associated with externalizing and internalizing problems in both boys and girls. Meanwhile, destructive marital conflict (i.e., avoidance-capitulation and verbal aggression) was significantly positively associated with externalizing problems in boys and significantly positively associated with internalizing problems in girls. These findings contribute to the substantial literature demonstrating the relationship between family processes and the development of disruptive behavior disorders in children.

A coaching program to improve quality of life in older people in Japan: a randomised controlled trial.

As the world's population ages, efforts to improve quality of life (QOL) in old age are gaining public attention. In this study, a programme was conducted for older people with the aim of clarifying their life goals related to QOL and the meaning of their existence, and the effect of the programme in improving QOL was evaluated. Participants were randomly assigned to the intervention or control group after registration. The program consisted of four 90-minute classes. The primary outcome was the Philadelphia Geriatric Center Morale Scale score (PGC), and changes in outcomes were compared between groups. The intervention group had significantly improved PGC scores (P<0.003). Further, the scores of PGC subscales 'Acceptance of one's own ageing' and 'Lonely dissatisfaction' showed significant improvements after the intervention (P<0.001). The findings suggest the effectiveness of the developed program in improving QOL in people aged ≥65 years.

Role of Parenting Style in Children's Behavioral Problems through the Transition from Preschool to Elementary School According to Gender in Japan.

While ineffective discipline can be attributed to authoritarian and permissive parenting styles, little research has examined the role of gender in the association between parenting style and early childhood behavioral problems. Thus, this study aimed to clarify the effects of authoritarian and permissive parenting on children's externalizing and internalizing behaviors during the preschool-to-elementary-school transition according to gender in Japan. A sample of 1668 Japanese children (853 boys and 815 girls) were followed longitudinally over one-year intervals, and assessed based on parenting styles (the Parenting Scale), children's behavioral problems (the Strengths and Difficulties Questionnaire), and family characteristics. Multivariate analyses revealed that, when analyzed by gender, authoritarian discipline influenced externalizing problems in boys (ß = 0.048, p = 0.047) and girls (ß = 0.067, p = 0.023), while permissive discipline influenced externalizing problems in boys only (ß = 0.049, p = 0.038). The results document the relationship between family processes and the development of disruptive behavior disorders in children. Support for parents employing such child-rearing styles in early childhood may be effective in reducing school maladjustment.

The relationship between the houseboundedness and frailty of community-dwelling elderly persons.

This study aimed to verify whether the incidence of frailty in elderly individuals is higher among those who are housebound than those who are not. This study found no correlation between elderly people's houseboundedeness and physical, mental, social, and overall frailty. However, the Tilburg Frailty Indicator (TFI) frailty score and grip strength value were higher in non-housebound elderly persons than in housebound elderly ones. This suggests that being housebound may lead to frailty. On the other hand, it is thought that individual interaction with family and friends, and lack of anxiety about falls correlates with the prevention of frailty in housebound elderly persons. The results of the study also suggest that the basic checklist may be effective for ascertaining the actual situation of housebound elderly people who may be manifesting frailty.

[Factors related to eating behaviors in early childhood: Relationships between autistic tendency, sensory characteristics, and childcare environment].

Objective　The objective of this study was to examine the influence of environmental factors on eating behaviors of children.Method　The participants were the caregivers of 1,678 children attending nursery schools or kindergartens in two different cities of a prefecture. We distributed several self-administered questionnaires to the caregivers in conjunction with collaborating organizations. The participants returned the questionnaires either to collection boxes placed at the collaborating organizations facilities or by mailing them. The questionnaires included assessment of the child's basic attributes, caregiver assessments of eating behaviors, the Social Responsiveness Scale (SRS) measure of autistic traits, the Japanese Sensory Inventory-Revised (JSI-R), and the Index of Child Care Environment (ICCE). We conducted a chi-square (χ2) test, Fisher's exact test, and a multiple regression analysis.Results　We received responses from 843 participants (response rate=50.4%), and of those, 583 were considered valid (34.7%). The mean number of problematic eating behaviors for each child as perceived by the caregivers was 2.43±2.26. In general, caregivers thought that about 40% of the children had an unbalanced diet and about 30% had a problem of "not being able to sit still." The multiple regression analysis showed that the number of problematic eating behaviors was significantly and positively affected by the SRS T-score total (ß=0.188, P<0.001), sense of taste (ß=0.319, P<0.001) and auditory sense (ß=0.168, P<0.001) in JSI-R. A positive relationship was found between the environmental factors of human stimulation (ß=0.096, P=0.010) and social support (ß=0.085, P=0.022). A negative relationship was found between sense of smell (ß=-0.108, P=0.013), number of siblings (ß=-0.100, P=0.005), age (ß=-0.077, P=0.029), and sex (ß=-0.091, P=0.010).Conclusion　Our study results showed that having an unbalanced diet and "not being able to sit still" were typical features of eating behaviors. The number of problematic eating behaviors was associated with personal factors such as autistic tendency and sensory characteristics, and also with environmental factors, such as human stimulation and social support. Our findings show the importance of evaluating all relevant factors when dietary guidance is provided in the treatment of problematic eating behaviors.

Association between mobile technology use and child adjustment in early elementary school age.

The time that children spend using digital devices is increasing rapidly with the development of new portable and instantly accessible technology, such as smartphones and digital tablets. Although prior studies have examined the effects of traditional media on children's development, there is limited evidence on the impact of mobile device use. The current study aimed to clarify the link between mobile device use and child adjustment. The sample included 1,642 children aged 6 in first grade at elementary schools in Japan. Parents completed a self-report questionnaire regarding their children's use of mobile devices and emotional/behavioral adjustment. We performed inverse probability of treatment weighted (IPTW) logistic regression to compute odds ratios (OR) for emotional/behavioral problems according to mobile device use. The values for IPTW analysis were computed based on variables assessing sociodemographics and child characteristics. Among the participants, 230 (14.0%) were regular users (60 minutes or more on a typical day) and 1,412 (86.0%) non-regular users (under 60 minutes on a typical day). Relative to non-regular use, regular use of mobile devices was significantly linked to conduct problems (IPTW-OR: 1.77, 95% CI: [1.03-3.04], p < .05) and hyperactivity/inattention (IPTW-OR: 1.82, 95% CI: [1.15-2.87], p < .01). Based on these results, routine and frequent use of mobile devices appear to be associated with behavioral problems in childhood.

A cohort study on elderly individuals newly certified as requiring long-term care: comparison of rates of care-needs certifications between basic checklist respondents/specific health examinees and non-respondents/non-examinees of 37,000 elderlies in a city.

Objective: The rates of care-needs certification were mainly compared between two cohorts: 7,820 specific health checkup examinees/basic checklist respondents and 29,234 non-examinees/non-respondents. Subjects and Methods: Among approximately 37,000 elderly citizens of X City, the number of individuals newly certified as requiring long-term care were observed from the date of the first specific health checkup in 2008 to March 31, 2013. The aggregated totals of these individuals and associated factors were evaluated. Results: 1. Support Required 1, Support Required 2, and Long-term Care Required (level 1) certified individuals accounted for approximately 80% of newly certified individuals aged 65-74 years. Newly certified individuals aged 75 years and over had similar results with 37.2% of them being certified Support Required 1, 19.4% certified Support Required 2, and 22.9% certified Long-term Care Required (level 1). 2. The primary factors for care-needs certification in individuals aged 65-74 years were arthritic disorder in 27.6%, falls and bone fractures in 11.3%, and malignant neoplasm and cerebrovascular disease, among others. This was similar for individuals aged 75 years or over. 3. Of the 7,820 specific health checkup examinees/basic checklist respondents, 1,280 were newly certified as requiring long-term care (16.4%) compared to 7,878 (26.9%) of the 29,234 non-examinees/non-respondents. Therefore, the latter cohort had a significantly higher rate of individuals who were newly certified as requiring long-term care. Conclusion: Both specific health checkups and basic checklists are effective health policies to protect frailty in community elderlies.

Effect of socioeconomic status on behavioral problems from preschool to early elementary school - A Japanese longitudinal study.

PURPOSE: Social inequalities are widely accepted to have a deleterious effect on children's mental health, and those with lower socioeconomic status generally experience more mental health issues. In this study, we examine the impact of socioeconomic situations of children's families during their early childhood on the children's social adaptation in Japanese elementary school. METHODS: The current investigation consisted of two sets of data relating to two separate years (with a one-year interval). The participants included preschoolers aged five years at Time 1 (the first year) and first graders aged six years at Time 2 (the second year); 1,712 met the inclusion criteria for both years. Parents of the participants completed a self-reported questionnaire regarding their SES (i.e., family economy and mother's education) and their children's mental health. Mental health was assessed using the Child Behavior Checklist/4-18, Parent Report. RESULTS: For each SES indicator, we found an inverse relationship across all the symptom dimensions. Specifically, bivariate analyses revealed that lower family income, maternal education level, and paternal education level predict all three domains of behavioral problems (i.e., internalized problems, externalized problems, and total behavioral problems). Further, multivariate analyses revealed that lower family income consistently predicts all domains of behavioral problems, lower maternal education level predicted externalized problems and total behavioral problems, and paternal education level did not predict any clinically significant behavioral problems. CONCLUSION: In this sample, we found that, for children, family income and parental education when entering preschool were significant predictors of mental health problems after elementary school enrollment; in particular, low income and low maternal educational achievement predicted a high probability of the development of a psychiatric disorder. A greater understanding of the mechanisms of these associations could contribute to improvements in interventions aimed at preventing child maladjustment.

A longitudinal study of socioeconomic status, family processes, and child adjustment from preschool until early elementary school: the role of social competence.

OBJECTIVE: Using a short-term longitudinal design, this study examined the concurrent and longitudinal relationships among familial socioeconomic status (SES; i.e., family income and maternal and paternal education levels), marital conflict (i.e., constructive and destructive marital conflict), parenting practices (i.e., positive and negative parenting practices), child social competence (i.e., social skills), and child behavioral adjustment (i.e., internalizing and externalizing problems) in a comprehensive model. METHODS: The sample included a total of 1604 preschoolers aged 5 years at Time 1 and first graders aged 6 years at Time 2 (51.5% male). Parents completed a self-reported questionnaire regarding their SES, marital conflict, parenting practices, and their children's behavioral adjustment. Teachers also evaluated the children's social competence. RESULTS: The path analysis results revealed that Time 1 family income and maternal and paternal education levels were respectively related to Time 1 social skills and Time 2 internalizing and externalizing problems, both directly and indirectly, through their influence on destructive and constructive marital conflict, as well as negative and positive parenting practices. Notably, after controlling for Time 1 behavioral problems as mediating mechanisms in the link between family factors (i.e., SES, marital conflict, and parenting practices) and behavioral adjustment, Time 1 social skills significantly and inversely influenced both the internalization and externalization of problems at Time 2. CONCLUSIONS: The merit of examining SES, marital conflict, and parenting practices as multidimensional constructs is discussed in relation to an understanding of processes and pathways within families that affect child mental health functioning. The results suggest social competence, which is influenced by the multidimensional constructs of family factors, may prove protective in reducing the risk of child maladjustment, especially for children who are socioeconomically disadvantaged.

A retrospective cohort study on the risk assessment of newly certificated long-term care need of elderly individuals in a community: Basic checklist and specific health checkup.

Objective: This study aimed to examine the factors influencing the requirement of a certificate of long-term care using a basic checklist and items listed in the Special Health Checkup. Method: This study included 7,820 individuals living in Uji city, who were selected from among 8,000 elderly individuals who, in 2008, underwent a specific health checkup (hereafter referred to as the 'specific health checkup for the old-old elderly individuals') for those aged 75 years and above. They answered questions from basic checklists at the time, and 180 individuals were excluded as they had already qualified for requiring the certificate of long-term care at the time of the checkup. The follow-up period extended from the day of the specific health checkup for the old-old elderly individuals to March 31, 2013. The data were analyzed using the certificate of needing long-term care as the response variable. The explanatory variables were the basic attributes, items listed in the specific health checkup for the old-old elderly individuals, interview sheets, and basic checklists. Cox proportional hazards regression analysis was conducted. Results: In total, 1,280 elderly individuals qualified for requiring the certificate of needing long-term care. The risk factors for the young-old elderly individuals aged 65 to 74 years were as follows: hepatic dysfunction (hazard ratio {HR}=1.69), the presence of subjective symptoms (HR=1.41), an above-normal abdominal circumference (HR=1.36), old age (HR=1.13), a reduced frequency of going out since the previous year (HR=1.87), the use of support for standing up after being seated on a chair (HR=1.86), no deposit or withdrawals made (HR=1.84), the anxiety of falling down (HR=1.50), an inability to climb stairs without holding a railing or wall (HR=1.49), as well as an increased difficulty in eating tough food items compared with 6 months prior (HR=1.44). The risk factors for the old-old elderly individuals were as follows: a positive reaction on proteinuria (HR=1.27), anemia (HR=1.18), old age (HR=1.10), inability to travel on a bus or train by themselves (HR=1.53), the inability to climb stairs without holding a railing or wall (HR=1.48), weight loss (HR=1.36), a reduced sense of appreciation of the activities they had previously participated in, over a span of 2 weeks (HR=1.30), the use of support for standing up after being seated on a chair (HR=1.23), and the anxiety of falling down (HR=1.20). Conclusion: The items listed in the specific medical checkup as well as the basic checklists were found to be risk factors for both the young-old elderly individuals and the old-old elderly individuals, indicating the need to utilize these lists for the prevention of nursing even in the late stages of life. Moreover, these results suggest the importance of screening elderly individuals suffering from hyperkinesis using the basic checklist and conducting preventive interventions in order to maintain and improve their physical functions.

Relations of mother's sense of coherence and childrearing style with child's social skills in preschoolers.

BACKGROUND: We examined the relationships between mothers' sense of coherence (SOC) and their child's social skills development among preschool children, and how this relationship is mediated by mother's childrearing style. METHODS: Mothers of 1341 Japanese children, aged 4-5 years, completed a self-report questionnaire on their SOC and childrearing style. The children's teachers evaluated their social skills using the social skills scale (SSS), which comprises three factors: cooperation, self-control, and assertion. RESULTS: Path analyses revealed that the mother's childrearing mediated the positive relationship between mother's SOC and the cooperation, self-control, and assertiveness aspects of children's social skills. Additionally, there was a significant direct path from mother's SOC to the self-control component of social skills. CONCLUSIONS: These findings suggest that mother's SOC may directly as well as indirectly influence children's social skills development through the mediating effect of childrearing. The results offer preliminary evidence that focusing on support to improve mothers' SOC may be an efficient and effective strategy for improving children's social skills development.

Marital relationship, parenting practices, and social skills development in preschool children.

BACKGROUND: This study examined the pathways by which destructive and constructive marital conflict leading to social skills development in preschool children, are mediated through negative and positive parenting practices. METHODS: Mothers of 2931 Japanese children, aged 5-6 years, completed self-report questionnaires regarding their marital relationship (the Quality of co-parental communication scale) and parental practices (the Alabama parenting questionnaire). The children's teachers evaluated their social skills using the Social skills scale. RESULTS: Path analyses revealed significant direct paths from destructive marital conflict to negative parenting practices and lower scores on the self-control component of social skills. In addition, negative parenting practices mediated the relationship between destructive marital conflict and lower scores on cooperation, self-control, and assertion. Our analyses also revealed significant direct paths from constructive marital conflict to positive parenting practices, and higher scores on cooperation and assertion. Positive parenting practices mediated the relationship between constructive marital conflict and higher scores on self-control and assertion. CONCLUSIONS: These findings suggest that destructive and constructive marital conflict may directly and indirectly influence children's social skills development through the mediation of parenting practices.

Concept of successful ageing among the community-dwelling oldest old in Japan.

AIM: In Japan, increasing human longevity has forced society to rethink the notion of what constitutes 'successful ageing'. This study attempts to advocate a new concept of successful ageing that involves complete acceptance of the ageing process. METHOD: Research was based on semi-structured interviews with 15 community dwelling oldest-old (aged 85 years and above) participants. The analysis was completed using a grounded theory approach. FINDINGS: Successful ageing for the oldest old was grouped into six categories. Within these categories, we discovered the structure of successful ageing, which synthesises ideas from the adaptation process with those of physical and cognitive decreased function as well as spirituality. CONCLUSION: The oldest old in Japan work to arrive at a conclusion with their lives, all the while coping with the drawbacks of ageing, such as declining physical and cognitive functions. This resilient and flexible way of life makes their form of ageing an equally 'successful' one.
