Abstract:
Lao Loum is the major ethnic group in Lao PDR, comprising nearly 70 percent of the
population. This study examines maternal factors and fetal factors among low birth weight
Lao Loum infants and suggests certain factors as determinants of low birth weight.
The data was collected in hospitals in Vientiane: Mahosot, Setathirat, and Mother and
Child hospital. The sample was 100 cases selected by purposive sampling. The data was
analyzed by using binary logistic regression.
The results indicate that 20 percent of respondents drank alcohol during pregnancy.
Sixty-five percent had medical care at least one time during pregnancy. More than 50 percent
took pre-natal vitamins for one month or more. More than one quarter had no education or
only primary education. More than 50 percent of these women worked at home as
housewives and looking after children. Nearly 20 percent of the women were adolescent
mothers. One quarter was shorter than 150 cm. Thirty-five percent weighed less than 45 kg.
Forty-two percent were underweight (BMI<20 kg/m²). Thirty-four percent gained less than
8kg in weight during the pregnancy. Nearly half knew their child’s sex before delivery (44
percent). Some of the mothers had complications during pregnancy; 10 percent had vaginal
bleeding and 8 percent had high blood pressure. Fifteen percent had previously had one or
more induced abortions. For 60 percent of the women it was their first baby. Thirty-six
percent of babies were born at preterm.
Having obstetric problems during pregnancy, such as urinary tract infections, having
suffered traumas such as those caused by traffic accidents, giving birth at less than 37 weeks
of pregnancy age, and poor maternal nutrition during pregnancy seem to be determinants of
low birth weight. Having had a previous induced abortion is also a determinant of low birth
weight.
Early prenatal care and contraception should be promoted. Further, the study would like
to suggest that future researchers on low birth weight in Laos should investigate more by
collecting and comparing similar data in other ethnic and religious groups such as Lao
Soung, Lao Theung, Vietnamese, Chinese, and Christian groups
