[Clinical-epidemiological study on newborn's apgar score in 'one minute' and relevant factors].
OBJECTIVE
To study the newborn's Apgar score in 'one minute' and relevant factors.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
