“…A number of possibilities can account for the reduced birth weights, including restricted placental blood flow and alterations in fetal growth hormone [43]. Prenatal maternal stress is also associated with low birth weight [44], although it is unlikely that the modest gravitational load utilized in this study produced significant stress in the dams. Research on adult male rats has shown that even at 2.0 ϫ g corticosterone levels are initially elevated at the onset of centrifugation, but the effect subsides after the fourth day following the onset of centrifugation [45].…”

A major goal of space life sciences research is to broaden scientific knowledge of the influence of gravity on living systems. Recent spaceflight and centrifugation studies demonstrate that reproduction and ontogenesis in mammals are amenable to study under gravitational conditions that deviate considerably from those typically experienced on Earth (1 x g). In the present study, we tested the hypothesis that maternal reproductive experience determines neonatal outcome following gestation and birth under increased (hyper) gravity. Primigravid and bigravid female rats and their offspring were exposed to 1.5 x g centrifugation from Gestational Day 11 either through birth or through the first postnatal week. On the day of birth, litter sizes were identical across gravity and parity conditions, although significantly fewer live neonates were observed among hypergravity-reared litters born to primigravid dams than among those born to bigravid dams (82% and 94%, respectively; 1.0 x g controls, 99%). Within the hypergravity groups, neonatal mortality was comparable across parity conditions from Postnatal Day 1 through Day 7, at which time litter sizes stabilized. Maternal reproductive experience ameliorated neonatal losses during the first 24 h after birth but not on subsequent days, and neonatal mortality was associated with changes in maternal care patterns. These results indicate that repeated maternal reproductive experience affords protection against neonatal losses during exposure to increased gravity. Differential mortality of neonates born to primigravid versus bigravid dams denotes gravitational load as one environmental mechanism enabling the expression of parity-related variations in birth outcome.

“…Many teenage mothers do not consistently access health care resources, and therefore, depression and other mental health problems may go unrecognized. Because adolescent mothers often have a history of trauma, lack sufficient social support and economic resources, and have an increased risk for depression,4,9,19,23,31 they should receive routine screening for depressive symptoms and other mental health disorders throughout their pregnancy and postpartum period. Early identification of depressive symptoms and effective mental health treatment may improve birth outcomes among this underserved population.…”

Study Objective Few studies have examined the effects of maternal depressive symptoms among adolescent women. The purpose of this study was to investigate the impact of depressive symptoms on birth outcomes of infants born to adolescent mothers. Design The medical records of pregnant adolescent patients were examined. Information about maternal depressive symptoms and birth outcomes was collected. Setting Data were collected at Washington Hospital Center, a nonprofit, community-based hospital that serves residents throughout the Washington, DC area. Participants Participants were 294 African-American and Latina adolescent mothers. Mean age was 16.2 years (standard deviation [SD] 1.4). Based on self-reports of depressive symptoms, adolescents were categorized by the following: no reported symptoms, depressive symptoms without SI/SA (suicidal ideation or attempt), and depressive symptoms with SI/SA. Main Outcome Measures Infant birth weight and gestational age at delivery. Results Over one-quarter of pregnant adolescents in this study reported symptoms of depression. Adolescents reporting depressive symptoms with SI/SA delivered babies that weighed 239.5 grams (98.3% confidence interval [CI] 3.9 to 475.1) less than babies born to mothers reporting depressive symptoms without SI/SA. There was no association between reported symptoms and gestational age. Conclusions Results suggest that compared to nonpregnant teens and adults, pregnant teens may have an increased risk for depression. Additionally, pregnant adolescents with suicidal ideation are at greater risk for delivering infants of lower birth weight compared with teens reporting depressive symptoms without SI/SA and teens reporting no symptoms. This study supports the need for early screening and treatment of depression for young pregnant women.

“…7,9 Stress and depression may have contributed to low birthweight as well. [12][13][14] Unfortunately, the Ecuador Demographic and Maternal-Child Health Survey did not collect information on maternal nutrition, stress, or depression during pregnancy. Data on weight gain were collected, but 36% of women did not report how much weight they gained during pregnancy.…”

OBJECTIVES: This study assessed the relationship between unintended pregnancy and infant birthweight in Ecuador, differentiating between unwanted and mistimed pregnancies. METHODS: Analyses focused on a subsample of women (n = 2490) interviewed in the 1994 Ecuador Demographic and Maternal-Child Health Survey. Logistic regression was used to assess the relationship between pregnancy intention status and low birthweight after control for other factors. RESULTS: Infants from unwanted pregnancies were more likely than infants from planned pregnancies to have low birthweight (odds ratio = 1.64, 95% confidence interval = 1.22, 2.20). Mistimed pregnancy was not associated with low birthweight. CONCLUSIONS: Unwanted pregnancy, but not mistimed pregnancy, is associated with low birthweight in Ecuador. Further research is needed to understand the mechanism through which pregnancy intention status affects birthweight.
