Clinical-epidemiological study on newborn's apgar score in 'one minute' and relevant factors / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the newborn's Apgar score in 'one minute' and relevant factors.</p><p><b>METHODS</b>One year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.</p><p><b>RESULTS</b>The Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.</p><p><b>CONCLUSION</b>Apgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.</p>

Comprehensive evaluation on the quality of life among rural elderly population in Anhui province / 中华流行病学杂志

<p><b>OBJECTIVE</b>To explore the feasibility of multi-dimensional and comprehensive evaluation on the quality of life among rural elderly population in Anhui province.</p><p><b>METHODS</b>5652 rural elderly people aged above 65 in Anhui province were selected by cluster sampling method and were studied by cross-sectional study through a questionnaire on health information. The quality of life was evaluated by comprehensive evaluation method.</p><p><b>RESULTS</b>The total score of satisfactory quality of life in the studied rural elderly people was 0.1432 +/- 0.5170, while not satisfied was -0.2521 +/- 0.6081, with significant difference between the two groups (F = 666.221, P < 0.0001). There was positive correlation between subjective satisfaction and total score of quality of life, with r(s) = 0.345 (P < 0.0001). The results of logistic regression analysis between comprehensive index of quality of life and subjective satisfaction indicated that filial piety, income, sleeping condition, chronic disease, nutrition status, economic dominance in the family, amusement activities etc. were important factors influencing the quality of life.</p><p><b>CONCLUSION</b>It was feasible to evaluation on the quality of life by comprehensive evaluation method.</p>

Early screening of cerebral palsy during infancy using 'Infant Motor Malfunction Profile' in the communities of two cities / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the prospective validity and predictive value of cerebral palsy during infancy, using 'Infant Motor Malfunction Profile'.</p><p><b>METHODS</b>Items of motor milestone in the profile was used as the first step to screen cerebral palsy on 8137 infants who were screened at 3, 6, 9, 12 months of age. The positive cases who had one of 7 developmental abnormal motor milestone items were examined using the items of primitive reflexes or postural reaction as the secondary step of cerebral palsy screening. The cases who had at least one abnormal item of primitive reflex or postural reaction received neurological examination by doctors to diagnose cerebral palsy.</p><p><b>RESULTS</b>According to our data, sensitivity, specificity, positive prospective value, positive and negative likelihood ratio of the profile in screening cerebral during infancy were 94.1%, 99.8%, 48.5%, 449.6 and 0.06, respectively.</p><p><b>CONCLUSION</b>The profile seemed to be an acceptable instrument for early identification of cerebral palsy.</p>

A prospective cohort study on injuries among school-age children with and without behavior problems / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the annual incidence of injuries and the relationship between behavior problems and injuries among school-age children.</p><p><b>METHODS</b>A prospective cohort study on injuries for 1-year follow-up period was conducted among 2 005 school-age children selected by cluster sampling from three primary schools in Maanshan city. They subjects were divided into two groups with or without exposure according to behavior problems rated by the Rutter Child Behavior Questionnaire at the beginning of the study. Nonparametric test was performed to analyze the differences in injuries between the two groups of children, and the influential factors for injuries were analyzed with multi-classification ordinal response variable logistic regression model.</p><p><b>RESULTS</b>The overall incidence rate for injuries in school-age children was 42.51%, while among children with and without behavior problems were 64.87% and 38.85%, respectively. There were significant differences between the two groups (u = -6.054, P = 0.000). However, the incidence rates of injuries in school-age children with antisocial (A) behavior, neurotic (N) behavior and mixed (M) behavior were 66.99%, 67.41% and 61.40%, respectively. No significant differences were found among them (u(A,N) = -0.052, P = 0.958; u(A,M) = -0.400, P = 0.689; u(N,M) = -0.364, P = 0.716). Multivariate analysis indicated that injuries in school-age children were associated with children behavior problems, maternal age at childbirth, bad conditions during mother pregnancy, education background of mother, prevention measures for safety at home and the child accompanied to travel between school and home by adults. Behavior problems of children seemed to be the major risk factors for injuries.</p><p><b>CONCLUSION</b>Children with behavior problems represented a significant risk group for injuries among school-age children. When planning intervention strategies on injuries, behavior problems should be emphasized to ensure optimal effectiveness of intervention.</p>
