Parity and Birth Weight in the Khanh Hoa Province, Vietnam~!2009-10-27~!2010-01-11~!2010-02-12~!

Abstract

This study aimed to assess maternal parity and its association with the birth weight of newborns in the Khanh Hoa province in the south-central part of Vietnam. In 2005, 240 consecutively admitted pregnant women in three main delivery clinics, both rural and urban, were enrolled. The women delivered 238 singleton newborns with a mean birth weight of 3201 grams (95% confidence limits: 3155, 3247). Vietnam has a strict two-child policy, but 10 percent were borne by women who had at least two previous deliveries. Thus, also women who give birth more than twice appeared to deliver in the public birth clinics. The adjusted birth weight was strongly associated with the parity, which means that population adherence to policies limiting the number of children to one or two influences the overall population mean and distribution of birth weight.

Etude du faible poids de naissance associé à l’âge maternel et la parité dans une population couple mère-enfant suivi à Lubumbashi

“…Cependant ceci n'est pas seulement observé dans les pays africains mais il s'agit d'une observation aussi bien pour les pays en développement que les pays développés. Au Vietnam, Vaktskjold trouve une association positive entre la parité et le poids de naissance indépendamment des autres facteurs de risque de FPN étudiés [ 48 ]. En 2006, l’étude menée en Inde par Bisai avait observé une différence significative de poids moyen à la naissance de 158 grammes entre les nouveau-nés des mères primipares et ceux des multipares en faveur de ces derniers [ 26 ].…”

Infant growth disparity in the Khanh Hoa province in Vietnam: a follow-up study

“…Our study sample met well the baseline inclusion criteria behind the WHO growth standard [ 5 ]. Namely, only singleton births delivered at term were included in the study sample; smoking in pregnancy was more or less absent [ 18 ]; and our data show that breastfeeding was common. Some 85 percent were breastfeeding at the time of follow-up, and only 4.6 percent breastfed less than 6 months.…”

“…The following baseline data were collected about each birth in a standard form: the name of the clinic, maternal age, weight, height, parity, gestational age (determined by date of last menstruation), pregnancy and delivery complications and delivery date, and neonatal 1-minute Apgar score, sex, birth weight, length, head circumference and presence of congenital malformations. Additional details about the enrolment and baseline data collection have previously been published [ 18 ].…”
