Lassek WD, Gaulin SJC. Does Nubility Indicate More Than High Reproductive Value? Nubile Primiparas' Pregnancy Outcomes in Evolutionary Perspective. EVOLUTIONARY PSYCHOLOGY 2021; 19:14747049211039506. [PMID: 34524917 PMCID: PMC10355305 DOI: 10.1177/14747049211039506] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/27/2021] [Accepted: 07/28/2021] [Indexed: 11/16/2022] Open
Abstract
The idea that human males are most strongly attracted to traits that peak in women in the nubile age group raises the question of how well women in that age group contend with the potential hazards of a first pregnancy. Using data for 1.7 million first births from 1990 U.S. natality and mortality records, we compared outcomes for women with first births (primiparas) aged 16-20 years (when first births typically occur in forager and subsistence groups) with those aged 21-25 years. The younger primiparas had a much lower risk of potentially life-threatening complications of labor and delivery and, when evolutionarily novel risk factors were controlled, fetuses which were significantly more likely to survive despite lower birth weights. Thus, nubile primiparas were more likely to have a successful reproductive outcome defined in an evolutionarily relevant way (an infant of normal birth weight and gestation, surviving to one year, and delivered without a medically necessary cesarean delivery). This suggests that prior to the widespread availability of surgical deliveries, men who mated with women in the nubile age group would have reaped the benefit of having a reproductive partner more likely to have a successful first pregnancy.

Factors Associated With Weight, Length, and BMI Change in Adolescents' Offspring in Their First Year of Life. Front Pediatr 2021; 9:709933. [PMID: 34532303 PMCID: PMC8438192 DOI: 10.3389/fped.2021.709933] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 07/29/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Young maternal age is associated with negative outcomes at birth and with offspring's growth. In low- and middle-income countries, adolescents' offspring growth little has been studied. Objective: To determine the association of maternal sociodemographic characteristics with weight, length, and BMI change in adolescents' offspring in their first year of life. Methods: This is a one-year follow-up study that included adolescent mothers and their offspring from 2010 to 2017. The infant anthropometric variables were performed at birth, 3, 6, and 12 months. Maternal health, pregnancy, and social variables were evaluated as well as birth outcomes. Crude, percentage, Z score, and percentile changes of weight, length, and BMI were evaluated from birth to 1-year-old. Statistical analyses were adjusted by maternal chronological age, socioeconomic status, breastfeeding duration, the timing of introduction of complementary feeding, among other variables. Results: We examined 186 dyads (mother-infant). The median maternal age was 15.5 years, and the mean pre-pregnancy BMI was 20. The mean gestational age was 39.1 weeks for infants, birth weight was 3,039 g, and length at birth was 49.5-cm. Maternal chronological age, the timing of introduction of complementary feeding, socioeconomic status, and maternal occupation were associated with offspring's weight gain at 12 months. Length gain was associated with exclusive breastfeeding. Socioeconomic status and occupation were associated with offspring's BMI change. When performing adjusted multivariable analyses, weight and length at birth were associated weight and BMI at 12 months. Conclusions: Weight at birth may negatively predict infant's weight and BMI changes at 12 months, while length at birth may positively predict the changes. Maternal chronological age, socioeconomic level, occupation, and the timing of the introduction of complementary feeding were associated with the weight change. Only exclusive breastfeeding was associated with length Z-score change in adolescents' offspring in their first 12-months of life.

Teenage pregnancy and experience of physical violence among women aged 15-19 years in five African countries: Analysis of complex survey data. PLoS One 2020; 15:e0241348. [PMID: 33108400 PMCID: PMC7591093 DOI: 10.1371/journal.pone.0241348] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Accepted: 10/13/2020] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Pregnant teenage women are prime targets of violence against women perpetrated by intimate partners, family members, and miscreants in their neighborhoods. This study estimated the prevalence of Teenage pregnancy (TP) and Physical Violence (PV) and further assessed the relationship between TP and PV in five Low-and-Middle-Income Countries (LMICs). METHODS The study was conducted among five LIMCs (Burkina Faso, Kenya, Malawi, Nigeria, and Tanzania) using data from the most recent Demographic and Health Surveys conducted in these countries. Modified Poisson with the robust standard error was used to quantify the association between TP and PV. All analyses adjusted for the complex survey design structure (clustering, weighting, and stratification). RESULTS The analysis involved a total of 26055 adolescent women aged 15-19 years across the five countries. The overall prevalence of TP was 25.4% (95%CI = 24.4-26.4) with the highest prevalence occurring among Malawians [29.0% (95%CI = 27.4-30.7)]. Meanwhile, the prevalence of TP among older adolescents (18-19 years) was approximately two-thirds significantly higher compared with young adolescents [aPR(95%CI) = 1.60[1.49-1.71)]. The prevalence of PV among teenagers across the five countries was 24.2% (95%CI = 22.3-26.2). The highest prevalence of PV was recorded among Nigerian adolescent women [31.8% (95%CI = 28.5-35.3)]. The prevalence of PV among adolescent women who were pregnant was approximately 5-folds significant compared to those who were not pregnant (adjusted prevalence ratio; aPR = 4.70; 95% CI: 3.86-5.73; p<0.0001). CONCLUSION There was a high prevalence of pregnancy among older teenagers aged 18-19 years. Close to a quarter of teenage women ever experienced physical violence. Pregnant teenage women ever experience of physical violence was very high compared to non-pregnant peers. Intervention should target PV and TP by adopting a gender-sensitive approach to eliminate physical violence, particularly among teenagers to prevent TP.

Teenage pregnancies in Mozambique: the experience of "Servicios Amigos dos Adolescentes" clinics in Beira. AJAR-AFRICAN JOURNAL OF AIDS RESEARCH 2018; 17:32-36. [PMID: 29504502 DOI: 10.2989/16085906.2017.1405825] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
The purpose of this article is to provide insights into the demand for pregnancy-related health services by adolescent girls and young women in Mozambique. We analysed the patient registers for the first year of operation (2014) of the Servicios Amigos dos Adolescentes (SAAJ) [Friendly Services for Adolescents] clinics in Beira, Mozambique. These registers provide details of the service demands of, and services provided to the 8 290 adolescent girls and young women who accessed the 6 SAAJ clinics in 2014. Analysis of that record, with disaggregation of the patients according to age (9 years or less; 10-14; 15-19; 20-24; 25 and older), show that 3 021 (36%) were pregnant or had previously been pregnant; most being girls in the 15-19 age band (59%). Being pregnant or having been pregnant previously was associated with dropping out of school. Of all the girls and women, 60% agreed to HIV testing and counselling; the HIV prevalence rate amongst this group was 4-5% amongst adolescents and 25% amongst women 25 years and older. A minority of the girls and women who were pregnant or had been pregnant previously agreed to HIV testing and counselling. Notwithstanding the limitations for analysis, the results were alarming: substantially high HIV prevalence rates were indicated (2% amongst 10-14 year old girls; 8% amongst 15-19 year olds; 10% amongst 20-24 year olds; and 28% amongst >24 year olds). The data from the SAAJ clinics and results pertain only to conditions in Beira. However, as the first empirical assessment of pregnancy-related service demand amongst adolescent girls and young women in the country and involving a relatively large sample, we contend that this study affirms the need for expansion of sexual and reproductive health (SRH) services, including HIV services, for adolescent girls and young women in Mozambique.

Abstract
STUDY OBJECTIVE Adolescent pregnancy is an important public health problem worldwide. It is associated with increased risk of maternal and fetal complications. We aimed to investigate whether adolescent pregnancies have an increased risk for perinatal complications. We focused primarily on the relationship between adolescent pregnancy and preterm delivery. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We used records of 38,646 women who gave birth at our hospital, between January 2008 and December 2009. Five hundred eighty-two randomly selected pregnant adolescents and 2,920 healthy parity and body mass index matched pregnant women 20-34 years of age were included the study. Perinatal outcomes were compared between the groups. RESULTS The mean gestational ages of the adolescent and control groups at the first prenatal visit were 11.2 (range, 8-31) and 8.5 (range, 7-28) weeks, respectively (P < .001). The risks of preterm delivery (odds ratio, 2.46; 95% confidence interval, 1.80-3.37; P < .001) and preeclampsia (odds ratio, 2.14; 95% confidence interval, 1.30-3.51; P = .002) were significantly greater among the adolescent mothers. In both groups, the most frequent reason was spontaneous preterm delivery. CONCLUSION As shown in this study, pregnant adolescents present to hospitals for prenatal care at a much more advanced gestational age compared with adults. At the time they present to the hospital, and particularly in the first trimester, they must be advised to undergo an ultrasound scan to determine the gestational age. As such, it would be reasonable to increase the frequency of examinations after the second trimester, because of the increased risk of preterm labor and preterm birth.

Abstract
BACKGROUND Young maternal age is variously defined in studies of its effect on obstetrics and perinatal outcomes. Also, pregnancy has been reported as the leading cause of death in adolescent girls in low- and middle-income countries. AIMS The aim of the study was to evaluate whether young maternal age was associated with an increased risk of obstetrics and perinatal adverse outcomes. STUDY DESIGN Case-control study. METHODS This case-control study was derived from a database of the medical records between January 2008 and December 2012. In the present study, 1374 teenage pregnancy and 1294 adult pregnancy cases were included. After restriction of analyses to singleton primiparous women, 1282 teenage pregnancy and 735 adult pregnancy cases were analyzed. Maternal age was separated into three groups: 15 and less, 16-19, and 20-34 years. Adjusted odds ratios (ORs) were derived through logistic regression models for the potential confounding factors. RESULTS Adolescents aged 15 years and younger had higher risks of preterm delivery, early preterm delivery, intrauterine fetal death and neonatal death compared with women aged 20 to 34 years after adjustment for confounding factors. In addition, both groups of adolescents had higher risks for anemia and episiotomy and lower risk of cesarean delivery. The rates of preeclampsia, gestational diabetes, chronic diseases, intrauterine growth restriction (IUGR) were higher in the adult group. CONCLUSION Younger maternal age was correlated with increased risks of preterm delivery, fetal and neonatal death and anemia.

Abstract
OBJECTIVE To determine the relationship between child marriage (before age 18 years) and morbidity and mortality of children under 5 years of age in Pakistan beyond those attributed to social vulnerabilities. STUDY DESIGN Nationally-representative cross-sectional observational survey data from Pakistan Demographic and Health Survey, 2006-2007 was limited to children from the past 5 years, reported by ever-married women aged 15-24 years (n = 2630 births of n = 2138 mothers) to identify differences in infectious diseases in past 2 weeks (diarrhea, acute respiratory infection [ARI], ARI with fever), under 5 years of age and infant mortality, and low birth weight by early (<18) vs adult (≥ 18) age at marriage. Associations between child marriage and mortality and morbidity of children under 5 years of age were assessed by calculating adjusted OR using logistic regression models after controlling for maternal and child demographics. RESULTS Majority (74.5%) of births were from mothers aged <18 years. Marriage before age 18 years increased the likelihood of recent diarrhea among children born to young mothers (adjusted OR = 1.59; 95% CI: 1.18-2.14). Even though maternal child marriage was associated with infant mortality and mortality of children under 5 years of age in unadjusted models, association was lost in the adjusted models. We did not find a relation between girl-child marriage and low birth weight infants, and ARI. CONCLUSIONS Girl-child marriage increases the likelihood of recent diarrhea among children born to young mothers. Further qualitative and prospective quantitative studies are needed to understand the factors that may drive child morbidity and mortality among those married as children vs adults in Pakistan.

Abstract
OBJECTIVE To evaluate longitudinal care needs and health service access among mother-infant pairs after adolescent pregnancy. METHODS In a case-control study, data were analyzed from primiparous adolescent and adult mother-infant pairs who delivered at Reunion Island University Hospital, France, between January 2004 and December 2006, and were followed-up from maternity discharge until December 2011. Infant outcomes were hospitalization during the first 2 years of life, hospital access for "non-medical" reasons, and neuropsychiatric care. Maternal outcomes were number of pregnancies and childbirths, rapid repeat pregnancy (RRP) rate, pregnancy morbidities, and use of health services. RESULTS Data from 476 cases and 476 controls were analyzed. Adolescent and control offspring did not differ in the measured outcomes. Adolescent and control mothers had, respectively, 2.4 ± 1.3 and 1.9 ± 1.1 pregnancies; 1.9 ± 0.8 and 1.6 ± 0.7 childbirths; and RRP rates of 7.6% and 2.7% (all P<0.001). Adolescents had less pregnancy-related pathologies at the index pregnancy and more frequently had natural deliveries (P<0.05). Younger mothers exhibited higher rates (19.7% versus 6.9%, P=0.001) of care for psychosocial reasons (suicide attempt, acute alcohol or drug intoxication, road accident, psychiatric problems, physical abuse). CONCLUSION Concerns arise from the long-term psychosocial risk among adolescent mothers.

Abstract
To evaluate the relationship between changes in fecundity rates and maternal age and the impact of maternal age on low birth weight (LBW) rates in a developed region in southern Brazil. A time series study evaluating birth weight and maternal ages through the born alive information system (SINASC) in Porto Alegre from 1996 to 2008. The Chi-square test for trends was used to evaluate the trend of LBW and fecundity rates at each maternal age. Population attributed risk (PAR) was used to calculate the impact of maternal age on LBW rates. The study included 271,100 newborns. There was a significant reduction in fecundity rates in all age groups younger than 34 years, but especially in the groups between 20 and 29 years. Overall LBW increased from 9.3 to 10.7 % (P < 0.001). The PAR for LBW showed a reduction in the group from 17 to 19 years (from 1.7 % in 1996-1999 to 0.1 % in 2004-2008), and an increase in the groups from 35 to 39 years (from 2.0 % in 1996-1999 to 2.3 % in 2004-2008) and above 40 (from 1.1 % in 1996-1999 to 1.5 % in 2004-2008). There was a significant change in fecundity pattern in the last 12 years in southern Brazil. Adolescent mothers were surpassed by mothers over 30 years of age in terms of vulnerability for LBW babies. The results show a change in the maternal age distribution towards older mothers, accompanied by an increasing incidence of LBW. This demographic transition also involved a paradoxical pattern with a remarkable reduction in fecundity rates in intermediate maternal age groups with concomitant increase in their risk for LBW.

Abstract
OBJECTIVE To determine the risk factors of adolescent pregnancies and to ascertain the effects of this condition on the maternal and infant outcomes. METHODS The study was carried out on 100 adolescent mothers less than 20 years of age and on a same number of adult mothers between 22 and 32 years of age and their infants. A socio-demographic attributes questionnaire form, a pregnancy follow-up and birth history form, and a mother and infant follow-up form were used. RESULTS The mean age of the adolescent mothers was 17.8 ± 0.7 years and that of the adult mothers was 26 ± 0.3 years. Income level of 83% of the families of adolescent mothers and 69% of the families of adult mothers was below the poverty line (p < 0.05). Dropout rate (i.e. rate of those not attending any school) was 36% in the adolescent group and 21% in the adult group. Rate of exclusively breastfeeding during the first 2 months was 40% in adolescents and 62% in adults (p < 0.01). Higher rates of adolescent mothers felt themselves inadequate infant care and with 7% of them experiencing problems in accessing a healthcare institution. CONCLUSIONS Properly following up adolescent pregnancies during prenatal and postnatal periods may be helpful for preventing the negative impacts on mother and infant health.

Abstract
OBJECTIVES To describe the maternal and neonatal outcomes of a large cohort of adolescent pregnancies in a tertiary care hospital at Reunion Island. METHODS Retrospective study of all primiparous singleton pregnancies over 10.5 years. Adolescent (<18 years) were compared to 18-29 years pregnancies. The maternal outcomes were obstetric illness, labor complications, and way of delivery. Neonatal outcomes were preterm birth, low birth weight (LBW), small for gestational age, birth asphyxia, need for mechanical ventilation, and mortality. RESULTS We analyzed 1839 adolescent pregnancies and 11,445 controls. Adolescents had worse prenatal care than older mothers, (4.4 vs. 1.4%; p < 0.0001), higher rates of smoking and alcohol assumption (13 vs. 11% and 0.7 vs. 0.4%, both p < 0.05). They showed less pregnancy-related illness and labor complications and higher rates of normal vaginal delivery (80 vs. 69%; p < 0.0001), without increased risk of episiotomy or postpartum hemorrhage. Offspring mortality, preterm birth, and LBW were higher in adolescent pregnancies (3.3 vs. 2.2%; p = 0.001, 14 vs. 12%; p = 0.0008; 17 vs. 14%; p = 0.002). CONCLUSIONS In this population, adolescents had an obstetrical outcome better than controls, but their offspring short-term outcomes were unfavorable. Furthers studies are needed to better elucidate the link between adolescent pregnancy and impaired neonatal outcome.
