Grandparental care and sleep disturbances in preschool children: a population-based prospective cohort study

Reliability and validity of the revised Chinese version of the Children's Sleep Habits Questionnaire (CSHQ-CH-R)

BACKGROUND

The Chinese version of the Children's Sleep Habits Questionnaire (CSHQ-CH) has been widely used in clinical practice and research since it was developed in 2007. This study aimed to examine the psychometric properties of the revised version (CSHQ-CH-R) and establish cut-off values for screening for sleep disturbances in Chinese preschool-aged and school-aged children.

METHODS

A community sample of 3850 preschool and school-aged children aged 3-12 years were obtained from 6 kindergartens and 2 primary schools in Shanghai, Beijing and Chengdu, China, from December 2019 to February 2020. A clinical sample of 119 children aged 3-12 years who were diagnosed with sleep disorders were recruited from a tertiary pediatric hospital in Shanghai from September 2019 to November 2021. Caregivers completed the original 33 items of the CSHQ-CH plus an additional 15 items through an online platform. Item analysis was conducted to develop the CSHQ-CH-R, which included discriminative validity, redundancy and ambiguity. Internal consistency, interobserver reliability, test-retest reliability, concurrent validity (correlations with actigraphy) and discriminative validity were then analyzed. The cut-off values for both the full scale and subscale scores were generated by receiver operating characteristics.

RESULTS

The final version of the CSHQ-CH-R included 30 items and 8 subscales. Three subscales (bedtime resistance, sleep duration and daytime sleepiness) were revised, and the other five subscales were unchanged from those of the CSHQ-CH. The internal consistency for the full scale was 0.83 for the community sample, and 0.73 for the clinical sample. The internal consistency ranged from 0.47 (sleep duration) to 0.72 (bedtime resistance) for the community sample, and 0.38 (sleep duration) to 0.83 (sleep-disordered breathing) for the clinical sample. The interobserver reliability for the full scale was 0.55, and ranged from 0.38 (parasomnias) to 0.74 (bedtime resistance) for the subscales. The test-retest reliability was 0.70 for the full scale, and ranged from 0.54 (sleep duration) to 0.78 (bedtime resistance) for the subscales. Concurrent validities against actigraphy were 0.62 and 0.33 for "time in bed" and "night sleep duration", respectively. The clinical sample scored higher than the community sample did for the full scale and subscales (P < 0.01). A cut-off total score of 44 was determined, with an area under the curve of 0.76, a sensitivity of 0.64, and a specificity of 0.76. To facilitate cross-cultural comparisons, psychometric properties and cut-off values for the CSHQ-CH with the original 33 items were also provided.

CONCLUSION

The CSHQ-CH-R exhibits satisfactory to good psychometric properties, indicating its suitability for identifying sleep problems among Chinese preschool- and school-aged children.

The Relationship Between Parental Childhood Maltreatment and Children's Sleep Quality: An Intergenerational Perspective

Based on the hyperarousal theory and self-control theory, this study investigated the link between parental childhood maltreatment and children's sleep quality by examining the mediation effect of parental self-control and children's perceived parental support from an intergenerational transmission perspective. A total of 334 Chinese primary school students in grades 4-6 (50% girls, Mage = 10.49, SD = 0.97) reported on perceived parental support and sleep quality. In addition, childhood maltreatment and self-control were reported by their parents (Mfather's age = 40.48, Mmother's age = 38.18). The results showed that the father's childhood maltreatment was directly associated with children's sleep quality, while the mother's childhood maltreatment was indirectly linked to children's sleep quality. Furthermore, children's perceived parental support acted as mediators in the effect of mother's childhood maltreatment on children's sleep quality, and mother's childhood maltreatment also affected children's perceived parental support via mother's self-control, thus affecting children's sleep quality indirectly. These results have important practical implications for family-based interventions in children's sleep quality.

The time sensitive and dose-responsive association between parental corporal punishment and sleep disturbances in preschoolers: A prospective cohort study

BACKGROUND

To examine whether parental corporal punishment is associated with increased risk of concurrent and later sleep disturbances among preschoolers, and whether the association is time-sensitive or dose-responsive.

METHODS

This 3-year prospective cohort study used data from the Shanghai Children's Health, Education and Lifestyle Evaluation, Preschool(SCHEDULE-P). Participants were newly enrolled preschoolers in November 2016(wave 1) and followed up in April 2018(wave 2) and April 2019(wave 3). Parents reported the children's corporal punishment experiences and sleep disturbances at each wave survey. Children's risk of sleep disturbances in relation to corporal punishment was examined using logistic regression, adjusting for children's age, gender, emotional/behavioral problems, family annual income, and maternal educational level.

RESULTS

The participants of 19,668 children included 9436(47.98 %) females, with a mean age of 3.73(SD = 0.29) years at wave 1. Exposure to corporal punishment was associated with increased odds of concurrent sleep disturbances at wave 1, 2, and 3 (aOR,1.57; 95 % CI, 1.40-1.75; P < .001; aOR,1.60; 95 % CI, 1.43-1.80; P < .001; aOR,1.74; 95 % CI, 1.54-1.95; P < .001), respectively. Exposure to corporal punishment at any wave of preschool was associated with increased odds of sleep disturbances at wave 3, and the risks were greater for proximal and accumulative corporal punishment exposure.

CONCLUSION

There is a time-sensitive and dose-responsive association between corporal punishment and sleep disturbance among preschoolers, with greater risk of sleep disturbances for proximal and accumulative exposure of corporal punishment. Promoting positive parenting strategies and avoiding corporal punishment can be a promising strategy to prevent and intervene sleep disturbances in preschoolers.

Association between sleep change patterns and mental health among preschoolers: The mediating role of resilience

Sleep disturbance has been recognized as an important factor influencing mental health problems in preschool children. However, no longitudinal studies have investigated the association between sleep change patterns and mental health in preschoolers or the mediating role of resilience. Here, data were collected from 1595 preschool children in 26 kindergartens in four counties in Anhui Province, China, who were followed up (T2) 1 year apart based on baseline surveys (T1). The primary caregivers of the children were asked to complete a structured questionnaire through face-to-face interviews or by completing it themselves. Pearson's correlation and linear regression were used to analyze the relationships among sleep patterns, mental health, and resilience in preschoolers. A structural equation model was used for the mediation analysis. Four patterns of sleep change were identified: persistent-low pattern (1.7%), decreasing pattern (9.8%), increasing pattern (7.3%), and persistent-high pattern (81.3%). Compared to the persistent-low pattern, the increasing pattern and persistent-high pattern were associated with emotional behavioral problems (EBPs) and anxiety. Resilience played a fully mediating role in the relationship between increasing pattern, persistent-high pattern, and EBPs. Resilience partially mediated the effects of increasing and persistent-high pattern on anxiety. More attention should be paid to sleep problems in children with increasing and persistent-high sleep patterns. Resilience is important for understanding the mechanism underlying the correlation between sleep patterns, EBPs, and anxiety. Considering the EBPs and anxiety of preschool children, early intervention for resilience should be considered.

A developmental perspective on sleep consistency: Preschool age through emerging adulthood

OBJECTIVE/BACKGROUND

Beyond sleep duration, the regularity of sleep patterns (e.g., sleep consistency), including variability in sleep timing (e.g., bedtime, wake time) and duration, is a critical marker of sleep health. Sleep consistency is captured using a variety of methods within the literature (e.g., sleep intraindividual variability, social jetlag), but most of the research focuses on adolescents.

METHODS

Drawing on a developmental perspective, this narrative review highlights how normative changes at the individual (e.g., biological, cognitive, and social) and contextual (e.g., home, school, sociocultural) levels may contribute to inconsistent sleep patterns across development.

RESULTS AND CONCLUSIONS

This review emphasizes how inconsistent sleep may increase across pivotal transitions throughout development (e.g., elimination of naps, puberty, summertime, entering college). Finally, recommendations for measuring sleep consistency and areas to address in future research are discussed.

The influence of sleep patterns and screen time on the sleep needs of infants and toddlers: A cross-sectional study

PURPOSE

The purpose of this study was to examine the effects of screen time and sleep patterns on the sleep needs of infants and toddlers.

DESIGN AND METHODS

A descriptive cross-sectional data were collected from 304 parents of children aged 6 to 36 months old. The screen use of children and parents was assessed with seven questions and A Brief Infant Sleep Questionnaire (BISQ) was used to assess infant sleep.

RESULTS

The results of this study indicate that children's adherence to the recommended sleep standards is poor. The most important criteria that caused poor sleeping were the number of awakenings at night, the duration of sleeplessness at night and the minimum total sleep time of <9 h. The most frequently used screen type in all of the age groups and parents was TV, followed by smartphones. As the age of the children increased, the rate of all screen-type use also increased. Factors predicting sleep needs included bedtime, the PED usage of children, parents' watching TV and care of the children by the babysitter.

CONCLUSIONS

Sleep needs are associated with the sleep patterns and screen usage of the children and parents.

PRACTICE IMPLICATIONS

Given that screen usage behaviors are tracked from infancy to early childhood, these findings highlight the need for prevention and intervention efforts, as well as for education and policy measures, to limit screen use and exposure from an early age.

Associations between gestational age and childhood sleep: a national retrospective cohort study

BACKGROUND

Both sleep quality and quantity are essential for normal brain development throughout childhood; however, the association between preterm birth and sleep problems in preschoolers is not yet clear, and the effects of gestational age across the full range from preterm to post-term have not been examined. Our study investigated the sleep outcomes of children born at very-preterm (<31 weeks), moderate-preterm (32-33 weeks), late-preterm (34-36 weeks), early-term (37-38 weeks), full-term (39-40 weeks), late-term (41 weeks) and post-term (>41 weeks).

METHODS

A national retrospective cohort study was conducted with 114,311 children aged 3-5 years old in China. Children's daily sleep hours and pediatric sleep disorders defined by the Children's Sleep Habits Questionnaire (CSHQ) were reported by parents. Linear regressions and logistic regression models were applied to examine gestational age at birth with the sleep outcomes of children.

RESULTS

Compared with full-term children, a significantly higher CSHQ score, and hence worse sleep, was observed in very-preterm (β = 1.827), moderate-preterm (β = 1.409), late-preterm (β = 0.832), early-term (β = 0.233) and post-term (β = 0.831) children, all p<0.001. The association of pediatric sleep disorder (i.e. CSHQ scores>41) was also seen in very-preterm (adjusted odds ratio [AOR] = 1.287 95% confidence interval [CI] (1.157, 1.433)), moderate-preterm (AOR = 1.249 95% CI (1.110, 1.405)), late-preterm (AOR = 1.111 95% CI (1.052, 1.174)) and post-term (AOR = 1.139 95% CI (1.061, 1.222)), all p<0.001. Shorter sleep duration was also found in very-preterm (β = -0.303), moderate-preterm (β = -0.282), late-preterm (β = -0.201), early-term (β = -0.068) and post-term (β = -0.110) compared with full-term children, all p<0.01. Preterm and post-term-born children had different sleep profiles as suggested by subscales of the CSHQ.

CONCLUSIONS

Every degree of premature, early-term and post-term birth, compared to full-term, has an association with sleep disorders and shortened daily sleep duration. Preterm, early-term, and post-term should therefore all be monitored with an increased threat of sleep disorder that requires long-term monitoring for adverse sleep outcomes in preschoolers.

Self-reported Adverse Childhood Experiences Among Custodial Grandmothers: Frequencies, Patterns, and Correlates

Given the scarce past research on custodial grandparents' early life circumstances, we investigated frequencies, patterns, and predictors of 14 adverse childhood experiences (ACEs) reported by 355 custodial grandmothers (CGMs). Predominant ACEs were bullying (54.6%), verbal abuse (51.5%), physical abuse (45.4%), and living with a substance abuser (41.1%). Only 11% of CGMs reported 0 ACEs, whereas 52.4% reported >4. Latent class analyses yielded three classes of ACE exposure: minimal (54.1%), physical/emotional abuse (25.9%), and complex (20.0%). Age was the only demographic factor related to ACE class, with the complex class being younger than the other two. MANCOVAs with age as a covariate revealed that different ACE profiles have unique impacts on CGMs' physical and psychological well-being. We conclude that ACEs are highly prevalent among CGMs and a serious public health concern. Future research addressing ACEs among CGMs is critical in order to support these caregivers and promote resilience in custodial grandfamilies.

The effects of received grandmothers' affection on adult grandchildren's health behaviors using affection exchange theory

BACKGROUND

Affection exchange theory (AET) explains the value of received affection for overall wellbeing in family relationships. However, this study extends prior work by investigating AET in grandmother-grandchild relationships and grandchildren's individual well-being. This study seeks to understand the relationships between adult grandchildren's received grandmother affection and health-related behaviors such as diet, exercise, substance abuse, and sleep.

METHODS

This cross-sectional study included 229 university student participants. Multiple regression analyses were performed to analyze received grandmother affection and grandchildren's health behaviors.

RESULTS

Using cross-sectional survey methods, it was found that grandchildren's reports of received memories and humor, and celebratory affection influenced grandchildren's dietary behaviors. Received love and esteem, memories and humor, and celebratory affection was also associated with grandchildren's exercise behaviors.

CONCLUSIONS

Grandchildren who receive grandmother affection may be likely to engage in the well-being process by engaging in health behaviors, while those who are not receiving affection might suffer the health consequences in adulthood. These findings support the assumption of affection exchange theory that received family affection, in this case, grandmother affection leads to positive health outcomes such as enhanced dietary and exercise behaviors among grandchildren.

Sleep disturbances and correlates among a sample of preschool children in rural China

This study aimed to explore the prevalence of sleep disturbances among preschool children in rural areas of China and identify the underlying associated factors. A cross-sectional study was conducted in rural areas of Anhui Province, China, from September 2019 to January 2020. The caregivers of children from 26 kindergartens completed the demographic questionnaire, the Children's Sleep Habits Questionnaire (CSHQ), the Strengths and Difficulties Questionnaire (SDQ), the Self-rating Anxiety Scale (SAS), and the adapted Identification and Management of Feeding Difficulties (IMFeD) tool. One-way analysis of variance, independent-samples t-test, and hierarchical multiple linear regression were conducted to explore the potential influencing factors of sleep disturbances in preschool children. For the specific sleep disturbances based on each subscale of the CSHQ, bedtime resistance (54.9%) and sleep anxiety (47.9%) were the most common types of sleep disturbances, followed by daytime sleepiness (21.3%), sleep duration (20.8%), parasomnias (16.5%), sleep-onset delay (12.6%), night wakings (12.2%) and sleep-disordered breathing (10.3%). The ages of children, children's emotional/behavioral problems, children's feeding difficulties, inconsistent parenting attitudes of parents, poor parenting styles, non-parent caregivers, and caregiver anxiety contributed significantly to the CSHQ total score, accounting for approximately 27.1% (R2 = 0.271) of the variance. Our study indicates that the prevalence of sleep disturbances among preschool children in rural areas of China is quite high. Furthermore, the potential risk factors are complicated, including factors related to both children and their caregivers.
