Emotional reactions, such as anxiety, irritability, and aggressive behavior, have attracted clinical attention as behavioral and emotional problems in preschool-age children.

To investigate the current status of family rearing, parental stress, and behavioral and emotional problems of preschool children and to analyze the mediating effect of the current status of family rearing on parental stress and behavioral/emotional problems.

We use convenience sampling to select 258 preschool children in the physical examination center of our hospital from October 2021 to September 2023. The children and their parents were evaluated using a questionnaire survey. Pearson's correlation was used to analyze the correlation between child behavioral and emotional problems and parental stress and family rearing, and the structural equation model was constructed to test the mediating effect.

The score for behavioral/emotional problems of 258 preschool children was (27.54 ± 3.63), the score for parental stress was (87.64 ± 11.34), and the score for parental family rearing was (31.54 ± 5.24). There was a positive correlation between the behavioral and emotional problems of the children and the "hostile/mandatory" parenting style; meanwhile, showed a negative correlation with the "support/ participation" parenting style (all P < 0.05). The intermediary effect value between the family upbringing of parents in parental stress and children's behavior problems was 29.89%.

Parental family upbringing has a mediating effect between parental stress and behavioral and emotional problems of children. Despite paying attention to the behavioral and emotional problems of preschool-age children, clinical medical staff should provide correct and reasonable parenting advice to their parents to promote the mental health of preschool-age children.

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

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.

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.

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

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.
