OBJECTIVESTo examine the bacterial quality of drinking water stored in containers by boat households in the river basin of Hue City, and associated factors.

METHODSReady-to-drink water stored in containers on boats was collected from 766 households. Escherichia coli (E. coli), total coliforms, and Enterobacteriaceae in the water were examined by the rehydratable dry-film plating method. Socioeconomic characteristics, water source, handling practices, and proficiency of disease prevention of individual households were assessed.

RESULTSE. coli, over ten counts of total coliforms, and over ten counts of Enterobacteriaceae were detected in 25.7, 44.5, and 51.5% of 1-ml samples of ready-to-drink water stored in containers on the boats. Bacterial contamination of the water stored in containers by boat households was significantly associated with use of river water as a source of drinking water, non-boiling before storing containers for drinking, and limited proficiency in disease prevention regardless of the influence of socioeconomic characteristics of the households (P < 0.01, P < 0.05, P < 0.01, respectively).

CONCLUSIONSBacterial contamination of ready-to-drink water stored by boat households was indicated. The households' proficiency in disease prevention buffered contamination. A comprehensive health promotion program with a wide range of contents is required for the communities of boat households.

OBJECTIVESThe aim of this study is to examine the utilities of antenatal care with comprehensive health education qualified in Phnom Penh for the health of mothers and infants during perinatal and postpartum periods. Attention was given to the existing socioeconomic disparties among women in this urban area, and the utilities were discussed irrespective of socioeconomic status.

METHODSA total of 436 pregnant women in an urban area in Phnom Penh were selected using a complete survey in randomly sampled villages and were followed up. Participating in antenatal care with comprehensive health education at least three time was regarded as the use of "qualified antenatal care" during pregnancy. In this study, we investigated the independent associations of the use of qualified antenatal care with the following outcome variables after the adjustment for the influence of socieconomic variables: postpartum maternal health knowledge, postpartum maternal anemia, low birth weight, and infant immunization.

RESULTSOf the 314 subjects who completed the follow-up examination, 66.8% used qualified antenatal care during pregnancy. The use of qualified antenatal care was positively associated with postpartum maternal health knowledge (OR=2.38, 95% CI: 1.12-5.05). and reductions in the incidences of postpartum anemia (OR=0.22,95% CI: 0.05-0.95) and low birth weight (OR=0.05,95% CI: 0.01-0.39) after the adjustment of the influence of socioeconomic status. The infants born to mothers who used qualified antenatal care had significantly higher coverage of BCG, DPT(1), and DTP(3) immunizations (P<0.001,P<0.001, andP<0.01, respectively), independent of their socioeconomic conditions.

CONCLUSIONThis study shows the solid utilities of qualified antenatal care in Phnom Penh for perinatal health.
