摘要
孕妇妊娠期生理发生变化,导致体成分改变,体重增长。临床表明肥胖孕妇比一般孕妇产科并发症明显增多,且多数是由于营养过剩所造成。本文在体成分分析模型的基础上,结合代谢分析和工程控制理论,利用营养对体成分的调节作用,提出了以孕妇体成分为控制目标,建立一个基于营养个体化定量的系统,通过测量人体代谢物消耗率和能量转换率可以确定出孕妇各种营养成分的日需要量,最终给出适当的、最为有效的营养干预方法,对孕妇体成分进行控制,使孕妇的体成分保持在理想状态,以减少畸形儿、巨大胎儿的产生,降低孕产妇的并发症。
The body composition of women changs with weight gain occurring during pregnancy. The traditional conception indicates that many pregnant women are over weight due to disequilibrium and malnutrition. The complications appear to be associated with over-feeding, since it occurs much more frequently in obese pregnant women rather than normal pregnant women. This paper targets the body composition of pregnant women, which is controlled by a combination of body composition analysis, metabolic analysis, the theory of control and nutritional interventions regarding body composition. The system is based on a personalized nutritional program. Appropriate nutritional intervention is used to keep up the optimal level of body composition. This requires accessing individual dietary intake and food consumption requirements. Special attention must be paid to ascertain the accurate nutritional requirements needed by the pregnant target. This will be measured using metabolic rate, the energy mctabelic rate, both which are able to minimize the risk of fetal abnormalities including fetal macrosomnia and other complications during pregnancy.
