Young Maternal Age (young + maternal_age)
Selected AbstractsPreterm delivery but not intrauterine growth retardation is associated with young maternal age among primiparae in rural NepalMATERNAL & CHILD NUTRITION, Issue 3 2007Christine P. Stewart Abstract Pregnancy during adolescence is associated with adverse birth outcomes, including preterm delivery and low birthweight. The nutrient availability to the fetus may be limited if the mother is still growing. This research aims to study the effects of pregnancy during adolescence in a nutritionally poor environment in rural Nepal. This study utilized data from a randomized controlled trial of micronutrient supplementation during pregnancy in south-eastern Nepal. Women of parity 0 or 1 and of age , 25 years who gave birth to a singleton liveborn infant who was measured within 72 h of delivery were included (n = 1393). There was no difference in the risk of low birthweight (OR = 0.96; 95% CI = 0.90,1.02) or small for gestational age (OR = 1.01; 95% CI = 0.94,1.08) per year of increasing maternal age among primiparae. Young maternal age did not affect the anthropometry or gestational age of the offspring of parity 1 women. Each year of increasing maternal age among primiparae was associated with increases in birth length (0.07 cm; 95% CI = ,0.01 to 0.16), head (0.05 cm; 95% CI = 0.01,0.09) and chest circumference (0.07 cm; 95% CI = 0.01,0.12), but not weight (9.0 g; 95% CI = ,2.1 to 21.8) of their offspring. Young maternal age was associated with an increased risk of preterm delivery among primiparae (OR = 2.07; 95% CI = 1.26,3.38) that occurred at an age cut-off of ,18 years relative to those 19,25 years. Thus, we conclude that young maternal age (,18 years) increased the risk of preterm delivery, but not intrauterine growth retardation, for the first but not second liveborn infant.

METHODS Birth defect cases were ascertained by the Metropolitan Atlanta Congenital Defects Program (MACDP), denominator information was obtained using birth certificate data. Infants with any chromosomal diagnosis were excluded. Effect estimates were calculated using 5-year maternal age categories with 25,29 years as the referent. Multiple logistic regression was used to adjust for maternal race, parity, infant sex, and birth year. RESULTS A total of 1,050,616 singleton infants, born after ,20 weeks gestation in the five counties of metropolitan Atlanta from 1968 through 2000 who did not have a chromosomal abnormality and whose mother was 14 to 40 years old, were included in the analyses, 32,816 of them were identified with birth defects by the MACDP. Young maternal age (14,19 years) was associated with anencephaly (OR = 1.81, 95% CI = 1.30,2.52), hydrocephaly without neural tube defect (OR = 1.56, 95% CI = 1.23,1.96), all ear defects (OR = 1.28, 95% CI = 1.10,1.49), cleft lip (OR = 1.88, 95% CI = 1.30,2.73), female genital defects (OR = 1.57, 95% CI = 1.12,2.19), hydronephrosis (OR = 1.42, 95% CI = 1.11,1.82), polydactyly (OR = 1.29, 95% CI = 1.09,1.52), omphalocele (OR = 2.08, 95% CI = 1.39,3.12), and gastroschisis (OR = 7.18, 95% CI = 4.39,11.75). Advanced maternal age (35,40 years) was associated with all heart defects (OR = 1.12, 95% CI = 1.03,1.22), tricuspid atresia (OR = 1.24, 95% CI = 1.02,1.50), right outflow tract defects (OR = 1.28, 95% CI = 1.10,1.49), hypospadias 2nd degree or higher (OR = 1.85, 95% CI = 1.33,2.58), male genital defects excluding hypospadias (OR = 1.25, 95% CI = 1.08,1.45) and craniosynostosis (OR = 1.65, 95% CI = 1.18,2.30). CONCLUSIONS Young and advanced maternal ages are associated with different types of birth defects. Underlying causes for these associations are not clear.

Purpose:, The purpose of this study is to describe and clarify the birth and prenatal characteristics of a large cohort of children with optic nerve hypoplasia. Methods:, This is a descriptive report of 204 patients aged , 36 months and enrolled in a prospective study at the Children's Hospital Los Angeles. Birth characteristics, including complications, were abstracted from study files and medical records. Systematic maternal interviews were conducted to obtain detailed prenatal histories. National birth data were used for comparison with birth findings. Results:, Birth characteristics were unremarkable for birthweight and gestation, but significant for increased frequency of caesarean delivery and fetal and neonatal complications. Young maternal age and primaparity were dominating maternal features. Preterm labour, gestational vaginal bleeding, low maternal weight gain and weight loss during pregnancy were prevalent. Conclusions:, These findings confirm young maternal age and primaparity as associated risk factors, challenge many other suggested factors such as alcohol and drug abuse, and introduce potentially significant prenatal characteristics such as maternal weight loss and early gestational vaginal bleeding as aetiological correlates.

[source] Maternal age and preterm births in a black populationPAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 2 2000Edem E. Ekwo Babies born to teenagers aged 15,19 years have a substantial risk of dying within the first year of life. Although associated socio-demographic factors may account for an increase in the risk of adverse reproductive outcomes for teenagers, there is a concern that young maternal age may also be a biological risk factor. We examined the effects of maternal age of primiparous black women on the incidence of preterm births using data from 6072 black women delivering between 1989 and 1995 at an urban perinatal network of 17 hospitals and health centres serving residents in a well-defined geographical area. Maternal age was grouped as: 15, 16,17, 18,19, 20,24, 25,29 or 30 years age groups. The 20,24 age group with the highest number of births and lowest preterm rate was used as the reference age. Preterm birth was defined as delivery < 37 completed weeks of gestation. Of the 6072 infants born to the cohort, 1170 (19.3%) were preterm. The unadjusted odds for a preterm birth for the 15-year-olds (odds ratio [OR] = 0.97; 95% confidence interval [CI], 0.69,1.36), for the 16- to 17-year-olds (OR = 1.21; CI = 0.94, 1.57) and for the 18- to 19-year olds (OR = 1.15, CI = 0.92, 1.43) were not significantly different from that for the reference group. The risk for the 25-to 29-year-old mothers was 1.26 times [CI = 1.05, 1.50] and for the > 30-year-old mothers 1.28 times [CI = 1.07, 1.52] that for the reference group. Adjustments using logistic regression analysis for the effects of maternal smoking, drug abuse during pregnancy, insurance status, having prenatal care and median family income from census tract of residence did not result in a significantly increased risk for preterm birth or low birthweight for the teenage groups compared with the reference group. We conclude that primiparous teenage black mothers do not have an inherent biologically increased risk for preterm births. [source] Does Postpartum Length of Stay Affect Breastfeeding Duration?BIRTH, Issue 3 2003A Population-Based Study Women leaving the hospital early may also have household responsibilities that could interfere with breastfeeding. This study examined the relationship between postpartum length of stay and breastfeeding cessation. Methods: This study used data from 10,519 respondents to the California Maternal and Infant Health Assessment (MIHA) surveys from 1999 to 2001. MIHA is an annual statewide stratified random sample, population-based study of childbearing women in California. Survival analysis was used to examine the relationship between length of stay and length of time breastfeeding. Women were asked about the number of nights their infant stayed in the hospital at birth, whether they breastfed, and if so, the age of the child when they stopped. Hospital stay was defined in three categories: standard (2 nights for a vaginal delivery, 4 nights for a cesarean section), or shorter or longer than the standard stay. Results: Approximately 88 percent of women initiated breastfeeding. Unadjusted predictors of breastfeeding cessation included short or long postpartum stay; young maternal age; Hispanic, African American, or Asian/Pacific Islander race/ethnicity; being unmarried; low income or education level; primiparity; being born in the 50 United States or the District of Columbia; smoking during pregnancy; and low infant birthweight. After adjustment for potential confounders, women with a short stay remained slightly more likely to terminate breastfeeding than women with a standard stay (relative risk, 1.11, 95% confidence interval 1.01, 1.23). Conclusion: Women who leave the hospital earlier than the standard recommended stay are at somewhat increased risk of terminating breastfeeding early.

[source] Early motherhood and disruptive behaviour in the school-age childACTA PAEDIATRICA, Issue 1 2004P Trautmann-Villalba Aim: To determine the significance of young maternal age, family adversity and maternal behaviour during mother-toddler interaction in the prediction of child disruptive behaviour at age eight. Methods: From an ongoing longitudinal study of infants at risk for later psychopathology (n= 362), 72 young mothers aged between 15 and 24 y (median 22 y) at first birth were compared with 197 primiparous older mothers ranging in age from 25 to 41 y (median 29 y). Family adversity at childbirth was assessed using a modified version of Rutter's Family Adversity Index (FAI) and measures of child disruptive behaviour at age eight were obtained using Achenbach's Teacher Report Form (TRF). An observational procedure was used to assess maternal behaviour during mother-child interaction at the age of 2 y. Results: Young mothers encountered more adverse family characteristics and were more inadequate, restrictive and more negative during interaction with their toddlers. Their school-aged children showed higher scores on all disruptive behaviour scales of the TRF. Hierarchical regression analyses revealed that family adversity and maternal behaviour during toddler interaction could account for most of the association between early motherhood and child disruptive behaviour. Conclusion: The impact of young motherhood on child mental health is not confined to teenage mothers and is mainly attributed to psychosocial and interactional factors. [source] | ||||||||||
