“…Advanced maternal age and low parity, common characteristics of the ART patients, are both considered risk factors for prematurity (40)(41)(42)(43). However, in our study there was no statistically significant difference in the maternal age between the two groups.…”

“…Years of Father's education was used as a proxy for socioeconomic status and was categorized into four groups: No education; less than High School (grades 1 through 8); High School (grades Advanced maternal age increases the risk for adverse pregnancy outcomes such as spontaneous abortion, low birth weight (LBW), infant mortality, and Down Syndrome. [1][2][3][4] In contrast to the attention devoted to the influence of maternal age on pregnancy outcome, little is known concerning the possible role of paternal age. One of the reasons for the greater focus on maternal age is the traditional attention that has been paid to maternal influences on fetal development.…”

The purpose of this study was to compare the effects of maternal and paternal age on Native American and Caucasian infants. Data were abstracted from birth records compiled in North Dakota from 1978 to 1992. Native Americans had a 45% higher risk for preterm births, a 140% higher risk for low birth weight (LBW) (<2500 g), and a 131% higher risk for very LBW (<1500 g) compared with Caucasians. Maternal and paternal age both had a "U-shaped" effect on preterm birth. However, while the risk for preterm birth was increased for both teenage mothers and fathers, the risk was also significantly increased only for mothers between the ages of 36-40 and 41-45. There was also a "U-shaped" relationship between LBW and parental age, and again the risk was statistically significant for different age groups. For mothers, the risk was decreased significantly for those 26 to 30 years of age, whereas for fathers, it was increased significantly for those <20 years of age. There was also a significant interaction between paternal age and race, with teenage Native American fathers having a slight (4%), but statistically significant, increased risk for having LBW children compared with teenage Caucasian fathers. The relationship between parental age and very LBW was also "U-shaped," but while the odds ratios for each maternal age group were significant, none of the odds ratios for any of the paternal age groups was statistically significant. The influence of teenage fathers on preterm and LBWs has not been previously reported, and the finding that paternal age has a greater influence among Native Americans is especially intriguing and deserving of further investigation.

“…Because of the increased frequency of maternal complications and required delivery interventions, they consider this as the real late pregnancy group [10,11]. However, clinical practitioners tend to consider pregnancies of women aged 35 years or more as high-risk pregnancies.…”
