Summary Introduction

To determine: The most common type of birth defect in the single-birth group.

Introduction: During the gestation period, the mother can have single birth or multiple births. Single birth is where the mother carries only one fetus during the gestation period in the womb. Multiple births are where more than one fetus is carried during the gestation period, such as twins, triplets, quadruplets, and more. Carrying more than one fetus in the womb results in insufficient supply of nutrient to the developing fetus. These fetuses become still-born or born with abnormalities.

Explanation of Solution

Scientist YT studied the correlation between birth defects and multiple births in City F from 1996 to 2000. The scientist calculated the relative risk of birth defect with factors including type of birth, maternal age, economy, race, and medical care provided during pregnancy. The relative risks were calculated using a scale of 1. Relative risk lesser than 1 indicate that multiple births possess less risk of the occurrence of respective birth defects. Relative risk greater than 1 indicates that multiple births do possess a greater risk of the same. The generated data are given in Fig. 42.16.

According to the study, heart defects were the most common type of birth defect in the single-birth group, which may be due to genetic disorders.

Conclusion

The most common type of birth defect in the single-birth group is heart defects.

Pregnant women are exposed to some physiological and psychological changes during the prenatal period. The aim of the study is to determine the effect of age factor on these physiological and psychological changes during pregnancy. The study included all adolescent (15-18 years) adult (19-34 years) and advanced age (35 years and above) pregnant women who applied to the clinic for 8 months in March 2003, and a total of n = 150 pregnant women, n = 50 from each group, were included in the study. is included. The research is planned as descriptive comparative. In the findings, it was found that there was a statistically significant difference in fatigue, frequent urination and respiratory distress compared to age groups (p <0.05). As a result of the study, it was revealed that age is not an important factor in both physiological and psychological changes of pregnant women.     Write down the purpose of this research, research questions, and key hypotheses / hypotheses.

Observation 1: 1 out of 2 first trimester abortuses show abnormal karyotypes with 96% caused by numerical abnormalities and 4% with structural abnormalities. At live birth, 1 out of 160 has abnormal karyotypes with 60% caused by numerical changes. This number increases with fetuses of mothers over 35 years old to 1/50 for total incidence and 85% for numerical changes. Questions: Think of reasons why it is important to maintain the number and structure of chromosomes. Why is maternal age so important?
Compare and contrast Aqua birth with the experience of a "traditional" childbirth. Include possible complications.
