Relationship Between Body Mass Index and Birth Weight Estimation Error of Mothers Admitted to Damnoensaduak Hospital, Ratchaburi Province
Keywords:
Birth weight, Body mass index, Estimation errorAbstract
The objective of this study is to investigate a relationship between birth weight estimation error and body mass index of mother. This study used two estimation methods, the first one has two variables, fundal height and abdominal circumference, and the second method has only fundal height as variable. Both results were compared with the birth weight to evaluate absolute errors at 10% and 20%. The better results and body mass indexes at different levels were then compared to figure out a relationship. Results indicate that:
The first method was more accurate than the other one. In addition, it was found that there is a positive relationship between mean percentage of estimation errors and mothers’ body mass indexes. At normal level of mother’s body mass indexes, the average value of birth weight estimation error starts at a negative value. Higher value of body mass index increases the error which becomes positive when body mass index passes overweight level. The error continues increasing with higher body mass index.
Therefore, professional nurses can use this relationship of the birth weight estimation error and body mass index found in this study could be used for a correction to obtain more accurate birth weight estimation.
