Purpose. Study the characteristics of the premature infant temperament characteristics and sleep. 2 explore the premature child temperament characteristics sleep time. Scope and Methodology 1. 1.1 preterm group: neurological rehabilitation clinic in Guangzhou Women and Children Medical Center were randomly selected born on April 1, 2009 to 2010, March 30, 2007, in the 28 weeks to 366 weeks gestational age, birth weight 1.5 to 2.5kg (1.5kg, not including 2.5 kg), to exclude congenital malformations, common genetic metabolic diseases and brain damage. A total of 100 cases, including 62 males and 38 females, the male to female ratio of 1.63:1, subjects months of age from 4 to 12 months, the mean age was 7.72 ± 2.48 months. 1.2 full-term group: Guangzhou Women and Children's Medical Center Children's Health Care, randomly selected born on April 1, 2009 to 2010, March 30, 2007, at a gestational age of 37 weeks to 42 weeks, birth weight, 2.5 to 4.0 kg (including 2.5kg does not include 4.0 kg), to exclude congenital malformations, common genetic metabolic diseases and brain damage. A total of 96 cases, including 63 males and 33 females, the male to female ratio of 1.91:1, subjects months of age from 4 to 12 months, the mean age was 7.34 ± 2.20 months. 2 Methods 2.1 Data collection: the inspectors under the guidance of parents of preterm group and the full-term group performance according to the baby 4 to 6 weeks of behavior and sleep respectively completed Carey4 months to 1 year old infant temperament rating scale and the self baby sleep questionnaire. 2.2: assessment, drawn nine temperament factor scores, according to the temperament factor score preterm group and the full-term group temperament is divided into easy to raise, intermediate, slow to start and the temperament of the preterm group and the full-term group is difficult to support type 4 temperament types. Will the baby sleep questionnaire information into EXCELL form fill and calculate the sleep time at night and sleep during the day time and night and day by day, the total sleep time. 2.3 Statistical Methods: group of preterm and full-term groups parental occupation, education level, perinatal conditions, feeding conditions, sleep environment, sleep habits, temperament type, sleep lines × list data chi-square test; according to the data whether normally distributed choice of two independent samples t test or Wilcoxon rank sum test was used to compare the preterm group and term group temperament factor parameters, sleep time difference; preterm group temperament factor parameters and the relationship of sleep time using bivariate correlation analysis; different. temperament preterm infants sleep time was used to compare the One-Way ANOVA analysis. All data application SPSS16.0 software for statistical analysis. Statistical analysis test level alpha = 0.05. 2. Preterm group and the comparison of the full-term group perinatal preterm group, the average gestational age of 34.09 ± 2.79 months, with an average birth weight was 2.14 ± 0.56kg, full-term group, the average gestational age was 38.33 ± 4.77 months, with an average birth weight was : 3.26 ± 0.48kg, the two data sets gestational age and birth weight difference was statistically significant (P lt; 0.05) Group of preterm and full-term group yellowish discoloration of skin subsided time difference was not statistically significant (P GT; 0.05) Two sets of data of the subjects had birth asphyxia, rescue history, history of bilirubin encephalopathy and has been doing newborn screening, screening results were normal. The two data sets miscarriage history, mode of delivery, yellowish discoloration of skin history was no significant difference (P gt; 0.05) Preterm group and the full-term group feeding patterns comparing the preterm group and the full-term group weaning time, complementary feeding time and start using the bottle, the use of dairy products and dietary characteristics was no significant difference (P GT; 0.05 ). Preterm group with the feeding patterns of the full-term group difference was statistically significant (P lt; 0.05), which preterm group were fed with artificial feeding, the highest proportion was 49%, while breastfeeding was 23%, 28% mixed feeding, full-term group by way of mixed feeding mainly (50%), breastfeeding and artificial feeding proportion of 27.1% and 22.9%, respectively. Preterm group with the full-term group sleeping habits compare two sets of data in the sleep environment, sleep preferences, sleeping position (when the sleep was prone posture), sleep was no significant difference (P GT stand up; 0.05) . Comparison preterm group of preterm group term sleep time sleep required more than 1 hour to 16, accounting for 16%; 0.5 to 1 hour and 24, accounting for 24%; 0.5 hours 35 , accounting for 35%; 5 to 10 minutes, 25 people, accounting for 25% of the full-term group, sleep onset latency greater than 1 hour, 5 (5.2%); 0.5 to 1 hour and 13, accounting for 13.5 %; 0.5 hours by 36 people, accounting for 37.5%; 5 to 10 minutes, 42 (43.8%), preterm labor sleep time than full-term children, the difference was statistically significant (P lt; 0.05) . Two sets of data during the day and the first paragraph of sleep time, sleep time during the day and the second paragraph, the third paragraph of daytime sleep time, sleep time during the day and the fourth paragraph of the total sleep time and daytime difference was not statistically significant (P gt; 0.05) Preterm group to wake up at night to sleep again the average time required is longer than the full-term group (13.44 ± 11.90min) (22.15 ± 17.54min), the difference was statistically significant (P lt; 0.05). The preterm group average night of total sleep time (9.53 ± 1.20h) compared to full-term group (9.96 ± 1.18h), the difference was statistically significant (P lt; 0.05). The preterm group average night of total sleep time during the day (13.31 ± 1.83h) compared to full-term group (13.71 ± 1.51h), but the difference was not statistically significant (P gt; 0.05) 6 preterm group term sleep of the group comparison group of premature children \Bai Tiansi sleep, inappropriate occasions, sudden onset of sleep the several sleep findings \) than full-term group (2.08%, 9.375%, 15.625%, 2.08%, 0.00%, 4.17%, 0.00%), the result is \90.00%, 93.00%, 86.00%, 95.00%) than full-term children (97.92%, 90.625%, 84.375%, 97.92%, 100%, 95.83%, 100%) less, the difference was statistically significant (P respectively lt; 0.01, lt; 0.01, lt; 0.05, lt; 0.05, lt; 0.01, lt; 0.05, lt; 0.05). Preterm group and the full-term group in fear and anxiety \difficulty in breathing while sleeping or even not breathing, snoring, hands and feet twitch or leg cramps, changing body position or kicked the quilt \Preterm group, with the full-term group temperament type composition and temperament factor parameter comparison preterm group is difficult to support type, intermediate the start slow proportion (21%, 45%, 10%) than full-term group (respectively 7.25 %, 31.3%, 6.25%), easy to raise the proportion of full-term group (55.2%) earlier production group (24%), the difference was statistically significant (P lt; 0.01). Preterm group in the nature of rhythm, aversion, adaptability, emotional, persistent five factor scores higher than the full-term group (3.24 ± 0.64,3.20 ± 0.78,3.03 ± 0.56,3.68 ± 0.67,3.58 ± 0.68) (2.92 ± 0.64,2.93 ± 0.62,2.78 ± 0.62,3.28 ± 0.49,3.16 ± 0.86), the differences were statistically significant (P lt; 0.01). 8 different temperament types of sleep time in the preterm group is relatively easy to raise and intermediate difficult to raise children start slowly night waking again after sleep onset latency difference was not statistically significant (P GT; 0.05), difficult to raise and Start slow night waking after sleep onset latency (28.81 ± 24.34,39.00 ± 17.12min) easier to support and intermediate (15.25 ± 16.28,18.98 ± 10.13min) children long difference was statistically significantEasy care type, intermediate and start the slow third paragraph of sleep during the day time difference was not statistically significant (P gt; 0.05), difficult to raise children during the day and the third paragraph of sleep time (0.31 ± 0.37h) easier to raise children (0.87 ± 1.05h), the difference was statistically significant (P lt; 0.05). Intermediate and difficult to support type, easy care type and other types of temperament children during the day and total sleep time between the difference was not statistically significant (P gt; 0.05), intermediate and difficult to raise temperament children during the day and total sleep time (respectively 3.40 ± 1.05,3.53 ± 1.31h) than the children start slow (4.47 ± 1.69h) less, the difference was statistically (P lt; 0.05).(13.10 ± 1.66h) easier to support and slow to start children (respectively 13.90 ± 1.57,14.10 ± 1.97h) less, the difference was statistically significant (P lt; 0.05), difficult to raise temperament children day total sleep time (13.17 ± 1.52h) easier to raise children (13.90 ± 1.57h), the difference was statistically significant (P lt; 0.05). 9 the preterm group temperament dimensions sleep time analysis aversion, adaptability, emotional nature, persistence and night waking in preterm children fall asleep again the time required for the correlation coefficient R to 0.181 (P lt; 0.05), 0.221 (P lt; 0.01), 0.207 (P lt; 0.01), 0.179 (P lt; 0.05); averse reaction threshold and night total sleep time correlation coefficient R were -0.168 (P lt; 0.05), -0.257 (P lt ; 0.01); levels of activity, intensity of reaction, the reaction threshold and daytime total sleep time correlation coefficient R were -0.258 (P lt; 0.01), the activity level of -0.161 (P lt; 0.05), 0.180 (P lt; 0.05); , aversion and preterm children at night daytime total sleep time correlation coefficient R were -0.223 (P lt; 0.01), -0.217 (P lt; 0.01)poor, retreat to new stimuli, to adapt to the slow, negative emotions, can not be sustained. 2 premature children sleep worse than full-term children, manifested as difficulty falling asleep, night waking, total sleep time of the night in preterm infants compared with full-term children short. 3 the different the temperament type preterm children sleep time difference, start slow and difficult to raise temperament premature children sleep easier for the time required to raise and intermediate children, total sleep time of the difficult temperament preterm children easier autotrophic; The premature child temperament dimensions of sleep time, in which the level of activity, the reaction strength, reaction threshold, aversion, adaptability, emotional nature of persistence were sleep time correlation.
