Abstract

Background: in Indonesia, the infant mortality is still high, if comparing to other Asean countries, thah is 4.6 times higher than in Malaysia, 1.3 times higher than in Philippines, and 1,8 times higher than in Thailand. The aims of this research was to determine the association of the neonatus mortality causes and age of mothers at the time delivering and birth assitant. Methods: data analyzed were data od Basic Health Research year 2007-2008 on RKD-07. Block AV1. The total samples were 257 infants. Analyze data with univariat, bivariat, and than logistic regresi binary. Results: result showed the neonatus mortality caused is the complication of temperature regulation 39.8%; the complication of pregnant and delivering mother is 23.4%; and also the causes of respiration and cardiovascular 23.1%. In the village, the neonatus mortality age is more than, and the neonatus mortality happened to be < 24 hours after delivering. Amount of mother with risk age ( > 20 years old and ≥36 year old) is more enough. The proportion of complication of mother with risk age is 24.3%, it is more high while the mother without risk age is 16.6%. Mother with risk age when delivering have risk 1,6 times to happen temperature regulation disorder in baby. In Village, the proportion of unsave deliverying midwive more high while save delivering midwive. The delivering with non medical provider have more enough risk 1,2 times to happen complication when delivering baby, have more enough risk 1,2 times to happen respiration and cardivascular disorder in neonatus, and have more high risk 1,6 times to happen temperature regulation disorder in neonatus. Mother with unsave deliverying midwive (non medical provider) have more high risk 3,7 times to happen hypertension or eclamsia while mother thaht helping by medical provider when deliverying baby, have more enough risk 2,7 time to happen long phase of delivering (long partus) and have more enough risk 1,02 times to happen premature/rupture membrane when delivering baby. Suggestions: It is suggested that the need to intensify education to the public, especially couples of childbearing age including pregnant women, husbands and families by health workers and cadres of health that seeks to avoid pregnancy at risk for maternal age range, ie > 20 years and > 36 years, pregnant women and families should always be directed to the maternity health workers when delivering baby, so the likelihood of either risk in infants and mothers during childbirth and after childbirth can be reduced. Besides needing skills upgrading of skills of health workers especially in the promotion of the importance of antenatal care through training and periodic refreshing. Key words: Neonatal Mortality, Risk Estimation
