Pregnancy after age 30 is considered late in the reproductive life of a woman and many obstetric clinicians believe that the older woman who is pregnant for the first time is at a greater risk statistically for labor dysfunction. This study was designed to discover whether or not a relationship exists between nulliparas over 30 and an increased frequency of labor dysfunction. The target population consisted of four groups of nulliparous women between the ages of 20 and 40 who delivered at Rose Medical Center and University Hospital between 1980 and 1983. Data gathered from each group consisted of objective evidence indicating the presence or absence of factors that fell under the definition of labor dysfunction. Chi-square analysis showed that a higher proportion of nulliparous women between the ages of 30 and 40 will experience some form of labor dysfunction when compared with nulliparous women between the ages of 20 and 29.
