Heterogeneous Consequences of Teenage Childbearing

Demography, December 2019, Pages 2147-2168
Abstract:
This study finds heterogeneous effects of teen childbearing on education and labor market outcomes across socioeconomic status and race. Using miscarriages to put bounds on the causal effects of teen childbearing, results show that teen childbearing leads to lower educational attainment, lower income, and greater use of welfare for individuals who come from counties with better socioeconomic conditions. However, there are no significant adverse effects for individuals who come from counties with worse socioeconomic conditions. Across race, teen childbearing leads to negative consequences for white teens but no significant negative effects for black or Hispanic and Latino teens.
Sex Differences in the Association of Family and Personal Income and Wealth with Fertility in the United States

Abstract:
Evolutionary theory predicts that social status and fertility will be positively related. It also predicts that the relationship between status and fertility will differ for men and women. This is particularly likely in modern societies given evidence that females face greater trade-offs between status and resource acquisition and fertility than males. This paper tests these hypotheses using newly released data from the 2014 wave of the Survey of Income and Program Participation by the US Census, which has the first complete measures of fertility and number of childbearing partners for a large, representative, national probability sample of men and women and also contains comprehensive measures of economic status as measured by personal and family resources, including income from all sources and all assets. Multivariate analyses show that personal income is positively associated with total fertility and number of childbearing unions for men only. For men, personal net worth is positively associated with number of childbearing unions; it is also positively associated with fertility for married men with a spouse present. These findings support evolutionary predictions of a positive relationship between status, access to mates, and reproductive success for males. Whereas personal income and personal net worth are negatively associated with total fertility and number of childbearing unions for women, family income (net of personal income) is positively associated with total fertility for women. For married men living with a spouse, family income (net of personal income) is negatively associated with total fertility. These findings are consistent with evolutionary theory given the existence of greater trade-offs between production and reproduction for women in an advanced industrial society. For women and men, family net worth (net of personal net worth) is negatively associated with number of childbearing unions and fertility. Implications are discussed.
Preliminary indications that the Attachment and Biobehavioral Catch-up Intervention alters DNA methylation in maltreated children

Development and Psychopathology, forthcoming
Abstract:
Maltreatment during development is associated with epigenetic changes to the genome. Enhancing caregiving may mitigate these effects. Attachment and Biobehavioral Catch-Up (ABC) is an intervention that has been shown to improve parent-child relationships and a variety of biological and behavioral outcomes among children that are involved in Child Protective Services. This preliminary study, using a small sample size, explored whether children who received ABC exhibit different methylation patterns than those who received a control intervention. The participants included 23 children aged 6-21 months who were randomized to receive ABC (n = 12) or a control intervention (n = 11). While the children displayed similar methylation patterns preintervention, DNA methylation varied between the ABC and control groups at 14,828 sites postintervention. Functional pathway analyses indicated that these differences were associated with gene pathways that are involved in cell signaling, metabolism, and neuronal development. This study is one of the first to explore parenting intervention effects on children's DNA methylation at the whole genome level in infancy. These preliminary findings provide a basis for hypothesis generation in further research with larger-scale studies regarding the malleability of epigenetic states that are associated with maltreatment.
The association between childhood maltreatment and empathic perspective taking is moderated by the 5-HTT linked polymorphic region: Another example of “differential susceptibility”
Vera Flasbeck et al.
PLoS ONE, December 2019
Abstract:
Previous research has suggested that the short (S)-allele of the 5-HT transporter gene-linked polymorphic region (5-HTTLPR) may confer “differential susceptibility” to environmental impact with regard to the expression of personality traits, depressivity and impulsivity. However, little is known about the role of 5-HTTLPR concerning the association between childhood adversity and empathy. Here, we analyzed samples of 137 healthy participants and 142 individuals diagnosed with borderline personality disorder (BPD) focusing on the 5-HTTLPR genotype (S/L-carrier) and A/G SNP (rs25531), in relation to childhood maltreatment and empathy traits. Whereas no between-group difference in 5-HTTLPR genotype distribution emerged, the S-allele selectively moderated the impact of childhood maltreatment on empathic perspective taking, whereby low scores in childhood trauma were associated with superior perspective taking. In contrast, L-homozygotes seemed to be largely unresponsive to variation in environmental conditions in relation to empathy, suggesting that the S-allele confers “differential susceptibility”. Moreover, a moderation analysis and tests for differential susceptibility yielded similar results when transcriptional activity of the serotonin transporter gene was taken into account. In conclusion, our findings suggest that the S-allele of the 5-HTTLPR is responsive to early developmental contingencies for “better and worse”, i.e. conferring genetic plasticity, especially with regard to processes involving emotional resonance.
Provision of Contraception in New York City School‐Based Health Centers: Impact on Teenage Pregnancy and Avoided Costs, 2008-2017

Perspectives on Sexual and Reproductive Health, December 2019, Pages 201-209
Context: Since 2008, the School‐Based Health Center Reproductive Health Project (SBHC RHP) has supported SBHCs in New York City (NYC) to increase the availability of effective contraception; however, its impact on teenage pregnancy and avoided costs has not been estimated.
Methods: The impact of the SBHC RHP on patterns of contraceptive use and on the numbers of pregnancies, abortions and births averted in 2008-2017 was estimated using program data and public data from the NYC Bureau of Vital Statistics and Youth Risk Behavior Survey. Data from the Guttmacher Institute on the cost of publicly funded births and abortions were used to estimate costs avoided; NYC-specific teenage pregnancy outcome data were employed to estimate the proportion of overall declines attributable to the SBHC RHP.
Results: Between 2008 and 2017, the SBHC RHP supported a substantial increase in the proportion of sexually active female clients using effective contraceptives. Most dramatically, 14% of clients in the SBHC RHP method mix used LARCs in 2017, compared with 2% in the non-SBHC RHP mix. The project averted an estimated 5,376 pregnancies, 2,104 births and 3,085 abortions, leading to an estimated $30,360,352 in avoided one‐time costs of publicly funded births and abortions. These averted events accounted for 26-28% of the decline in teenage pregnancies, births and abortions in NYC.
