BACKGROUND: This study sought to assess the relationship between the development of infant sleep/wake patterns, temperament and overall mental, motor and behavioural development over the first year of life. We hypothesised that infants with more regular sleep/wake patterns and longer sleep durations would have an easier temperament and higher developmental scores. STUDY DESIGN: Sleep/wake characteristics were recorded with the use of both parental sleep diary and actigraphy (Actiwatch AW64, Mini Mitter Company Inc, Sunriver, OR, USA) in 20 healthy term infants at monthly intervals over the first year of life. Temperament was assessed using the Early Infant Temperament Questionnaire (EITQ) at 3 months and the Revised Infant Temperament Questionnaire (RITQ) at 6 and 11 months and mental, motor and behavioural development at 12 months using the Bayley Scales of Infant Development II (BSID-II). RESULTS: At all 3 ages studied increased nocturnal sleep was correlated with increased approachability. In addition, at 11 months increased diurnal sleep duration was also correlated with increased rhythmicity and adaptability. At 12 months of age decreased daytime sleep duration was correlated with emotional regulation. CONCLUSIONS: Our findings highlight the importance of considering maturational and regulatory aspects of sleep when evaluating infant daytime behaviour. We suggest that concerns regarding sleep characteristics should become a significant aspect of clinical assessment and diagnosis of developmental delay or behaviour problems, particularly in the first year of life. 相似文献

BACKGROUND: Disturbed growth of the trunk may result in abnormal sternocostal relationship and a variety of pectus deformities. AIMS: The purposes of this study were to establish norms of trunk anthropometry for dysmorphology identification in the newborns and to evaluate chest circumference as a predictor for low birth weight for outborn infants where weighing scales were unavailable. STUDY DESIGN AND SUBJECTS: A total of 10,339 Chinese infants (5478 males, 4861 females) with gestation 24-42 weeks from 12 hospitals were included. The anthropometric measurements analyzed included chest circumference, inter-nipple distance, sternal length and abdominal circumference. OUTCOME MEASURES: The LMS method using maximum penalized likelihood was used to perform model fitting of the anthropometric centiles for these physical parameters. RESULTS: References tables of the four physical parameters for newborns were constructed. Chest circumference showed the highest correlation with birth weight (male: r = 0.866, female: r = 0.883). The cut-off points for chest circumference of 295 (male) and 299 mm (female) were the best predictor for low birth weight. There were also racial differences in these parameters. When compared with French infants, Chinese newborns had smaller chest circumference. CONCLUSION: These physical parameters provide useful references and aid dysmorphology diagnosis in newborns of ethnic Chinese origin. 相似文献

Few studies have investigated the velocities of fetal growth. The aim of the present study was to determine the pattern of 'fetal' growth velocities in a Chinese population. The gestation-specific measurements of the body weight, body length and head circumference in a representative sample of 5,045 male and 4,484 female newborns delivered between 26 and 42 weeks of gestation at 12 hospitals in Hong Kong were obtained. Peak growth velocity occurred before 30 weeks of gestation for head circumference, at week 30 for length and at week 30 for weight. When compared with data obtained from a French population, a significant difference in the growth velocity for body weight was observed below 32 weeks between French and Chinese infants, suggesting an ethnic difference in fetal growth of this parameter. 相似文献

Background: Actigraphy has been widely used in adults and children for the determination of sleep and wake. However, there have been limited studies in infants and to date there have been no studies to validate the reliability of actigraphy in preterm infants.
Aim: To evaluate the usefulness of actigraphy in preterm infants in a neonatal unit setting for determining sleep–wake by comparing results with those recorded from behavioural observations.
Methods: Thirty-eight studies were carried out in 10 preterm infants (8M/2F) born at 29–34 weeks gestational age. Sleep–wake patterns were assessed over 24 h with behavioural observations and compared to actigraphy (Actiwatch AW64, Mini Mitter Company Inc., Sunriver, OR, USA). The studies were grouped into gestational ages 30–33 weeks (n = 8), 34–36 weeks (n = 20) and 37–40 weeks (n = 10).
Results: Overall, on the low-activity threshold we found agreement rates of 84.5–88.9% between actigraphy and behavioural scoring with the predictive value for determining sleep (PVS) being between 91.3% and 95.6% and sensitivity between 88.2% and 96.8%. However, the actiwatch was not reliable for determining wakefulness with low values for predictive value of wake (PVW,31.1–53.7%) and specificity (31.5–33.6%).
Conclusion: Actigraphy can be used as a reliable indicator of sleep patterns in preterm infants in the neonatal unit setting. 相似文献

Vitamin D status of Hong Kong Chinese infants 总被引:1,自引:0,他引:1
Vitamin D deficiency is a common nutritional problem of weaning infants in many parts of the world. Hong Kong infants, who are fed with traditional rice-based weaning foods and live in crowded high rise flats, might be expected to suffer from this nutritional problem. Yet a study of 150 bottle fed infants revealed that the vitamin D intake from fortified milk and cereals was more than half of the recommended amount throughout the first 18 months and that the serum 25-OH vitamin D concentration of the infants at 18 months was normal. The effect of sunlight was also evident. 相似文献
