Description

As the object for this study, 100 pregnant women were observed, using the technique of non-linear analysis of Fingertip Pulse Wave. The authors inspected features of pregnancy during the early/mid/late terms. Using the Largest Lyapunov Exponent (LLE) as an index, the Fingertip Pulse Wave analysis shows mental adaptability (wellness), and the state of stress and relaxation due to the Autonomic Nerve Balance (ANB) of the sympathetic nerve and parasympathetic nerve. The results of both LLE and ANB showed 6 patterns. Breakdown of the above data is as follows: “ideal zones” were 36.3%, “associate ideal zones” were 51.0%, “depression zones” were 3.9%, “instinct zones” were 2.0%, “strained zones” were 2.9%, and “relaxed zones” were 3.9%. Of the subjects, 3.0% were considered as “high-stress” persons. The average of LLE was 5.18 in early pregnancy, 4.84 in mid-term pregnancy, and 4.05 in late pregnancy. The “wellness”factor showed a significant decrease throughout the progression of the pregnancy (p = 0.010). In addition, the measurements of fatigue and depression showed a marked increase (p = 0.027, p = 0.006), and risk factors increased as well. It was suggested that the symptom of morning sickness in early pregnancy influenced feelings of “physical weariness”, “upset stomach”, and “troublesomeness”. In late pregnancy, some people experienced an additional feeling of financial burden. Compared to measurements from one month past, when observing the ratio of women who felt an awareness of fatigue, uneasiness, and depression, the current Fingertip Pulse Wave readings were markedly higher, and the risks of fatigue, uneasiness, and depression increased. It is necessary to strengthen the support of the core issues of human resources and the economic base from early pregnancy on. In the future, we believe it is important to utilize the Fingertip Pulse Wave and Minor Trouble Evaluation Scale in prenatal examinations, to work together with pregnant women in visualization and objective evaluation of the results as a basis for healthy prenatal care.
