Exposure to electronic media was negatively associated with speech and language development at 18 and 24 months
Aim: This study evaluated early speech and language development at 18 and 24 months, and associated factors, based on parental reports. Method: We followed up the CHILD-SLEEP birth cohort of 1667 Finnish-speaking families, who were randomly recruited in 2011–2013 during routine visits to maternity clinics in the Pirkanmaa Hospital District of Finland. The women were approximately 32 weeks’ pregnant at enrolment. Parents reported the size of their child's expressive vocabulary, word combinations, intelligibility, finger-pointing and adherence to instructions. A subsample was studied using the Expressive Language subscale of the Bayley Scales of Infant and Toddler Development, Third Edition. Results: The children's vocabulary was smaller than previously reported. At 18 months of age, 68.8% of the 997 children had a vocabulary of 20 words or less and 35.7% used about five words at most. At 24 months, 32.4% of the 822 children had a vocabulary of 50 words or less and 18.4% used about 20 words at most. Longer child and parental exposure to electronic media was negatively associated with the size of the child's expressive vocabulary. Conclusion: Vocabulary size at 18 and 24 months was smaller than previously reported and negatively associated with exposure to electronic media.Aim This study evaluated early speech and language development at 18 and 24 months, and associated factors, based on parental reports.

Development, fabrication and evaluation of textile electrodes for EDA measurements
In this study, textile-based dry electrodes that are integrable to clothing were developed, and their potential and limitations in EDA measurements were characterized. Copper-based and silver-based fabric electrodes and two types of electrodes embroidered from conductive thread were tested for EDA-measurements from fingers, and their performance was compared to that of commercial Ag/AgCl electrodes. Based on the experiment results, stimulus response of skin conductance could be measured with all the electrodes. Copper-based fabric and densely embroider silver electrodes give the best EDA response, which is comparable to that of commercial Ag/AgCl electrodes. The next step is to integrate these textile electrodes into gloves and socks and carry out EDA measurements on female and male adults as well as on children. Our goal is that these EDA measurement clothes would become a part of our everyday life, which would enable versatile health and well-being related applications.acceptedVersionPeer reviewe
Night Awakening in Infancy : Developmental Stability and Longitudinal Associations With Psychomotor Development
Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor development (Bayley Scales of Infant and Toddler Development [Bayley-III]; Bayley, 2009) was investigated in infants with (>= 3 night awakenings, n = 81) and without fragmented sleep (Peer reviewe
Prenatal and Postnatal Predictive Factors for Children's Inattentive and Hyperactive Symptoms at 5 Years of Age: The Role of Early Family-Related Factors
We examined several parent-reported prenatal and postnatal factors as potential risk factors for attention-deficit and hyperactivity disorder (ADHD) symptomatology in 5-year-old children. Our study is based on the CHILD-SLEEP birth cohort. Several parental questionnaires were collected prenatally (32nd pregnancy week) and postnatally (i.e. child aged 3, 8, and 24 months and at 5 years). At 5 years of age, ADHD symptoms were assessed using questionnaires. Our main results showed that being a boy, parental depressive symptoms, more negative family atmosphere or a child’s shorter sleep duration, and maternal authoritarian parenting style predicted inattentive/hyperactive symptoms. Maternal and paternal authoritative parenting style predicted less inattentive/hyperactive symptoms. Children with several risk factors together had the highest risk for inattentive/hyperactive symptoms. Our findings emphasise the need for early screening and treatment of parental mental health, and early evidence-based targeted parental support, to enable early intervention in those children at a risk of developing ADHD.Peer reviewe
Maternal and paternal depressive symptoms and children's emotional problems at the age of 2 and 5 years: a longitudinal study
Signaled night awakening and its association with social information processing and socio-emotional development across the first two years
Study objectives: Night awakening is common in infancy, and some infants continue to have signaled night awakenings throughout early childhood. However, the influence of signaled night awakening on children's social development is less explored. In the present study, longitudinal associations between signaled night awakening, social information processing, and socio-emotional development were measured within the CHILD-SLEEP birth cohort in two groups formed based on parent-reported night awakenings. Methods: At 8 months, there were 77 infants in the waking group (≥3 awakenings) and 69 infants in the nonwaking group (≤1 awakening). At 8 and 24 months, social information processing was measured as children's attention to neutral and emotional faces, and at 24 months, parent-reported socio-emotional behavior was measured with the Brief Infant Toddler Social Emotional Assessment (BITSEA) questionnaire. Results: The two groups showed different patterns of attention to emotional faces. The waking group had a more pronounced attentional bias to fearful vs. happy faces, whereas in the nonwaking group, attention to fearful and happy faces did not differ. In addition, at 24 months, the waking group had more dysregulation problems and lower social competence than the nonwaking group, but no clear differences in internalizing or externalizing problems were found. Conclusions: Our results contribute to the literature by showing that during the first two years of life, signaled night awakening is associated with social information processing and socio-emotional behavior.Study objectives: Night awakening is common in infancy, and some infants continue to have signaled night awakenings throughout early childhood.

Parent-reported early sleep problems and internalising, externalising and dysregulation symptoms in toddlers
Background The concurrence of sleep and socio-emotional development in children is well accepted. However, the predictive role of sleep problems in infancy and the development of emotional and behavioural problems later in childhood remain still unclear. Therefore, in this study we examined the associations between sleep problems in early childhood and internalising, externalising and dysregulation symptoms in toddlers. Methods 1679 families entered the study during pregnancy and 936 children participated at 24 months. Parent-reported sleep duration, sleep-onset latency, night wakings, proportion of daytime sleep and bedtime at 3, 8, 18 and 24 months were assessed with two sleep questionnaires. Externalising, internalising and dysregulation problems at 24 months were examined with the Brief Infant-Toddler Social and Emotional Assessment. Results Short sleep duration at 3 and 8 months, more night wakings at 3, 8, 18 and 24 months and greater proportion of daytime sleep at 24 months were associated with internalising symptoms. Shorter sleep duration at 8, 18 and 24 months and longer sleep-onset latency and more night wakings at all time points, in addition to earlier bedtime at 8 months and greater proportion of daytime sleep at 24 months, were related to dysregulation. Finally, more night wakings at 3 and 24 months, and longer sleep-onset latency at 24 months were associated with externalising problems. Conclusion Shorter sleep and poorer sleep quality in infancy were prospectively related to emotional and behavioural symptoms in toddlers, and these associations were strongest for internalising and dysregulation symptoms. This study contributes to the recent research on the role of early sleep problems in socio-emotional development, suggesting that shorter sleep duration, longer sleep-onset latency and higher waking frequency are related to internalising, externalising and dysregulation symptoms in toddlers, and thus it might be beneficial to provide early interventions for those infants reporting these sleep problems.Peer reviewe
