Intergenerational Replication of Teenage Pregnancy and Educational Attainment in Mexico

Prenatal care utilization and perinatal outcomes among pregnant adolescents in Mexico, 2008-2019

OBJECTIVE

To describe utilization of prenatal care and outcomes of low birth weight and preterm birth among adolescent births in Mexico.

METHODS

We used birth certificate data and included live births to individuals 10-24 years, 2008-2019. Our outcomes were binary measures of adequate prenatal care, low birth weight, and preterm birth. We compared adolescents (10-14 years, 15-16, and 17-19) to those 20-24 years. We included individual-, clinical-, and municipality-level variables, used multivariable logistic regression, and calculated adjusted predicted probabilities. We also tested whether receipt of prenatal care moderated the relationship of age with preterm birth and low birth weight.

RESULTS

We included a total of 12 106 710 births to women 10-24 years. The adjusted predicted probability of adequate prenatal care increased with age: 56.07% (95% CI 55.82-56.31%) adjusted probability among adolescents 10-14 years compared with 65.51% (95% CI 65.48%-65.55%) among individuals 20-24 years. Receipt of adequate prenatal care in part mitigated disparities in preterm birth and low birthweight across all age groups: 7.30% (95% CI 7.17%-7.43%) adjusted probability of delivering a preterm infant among those 10-14 years who received adequate prenatal care compared with 9.37% (95% CI 9.20%-9.53%) among those 10-14 years without adequate prenatal care.

CONCLUSION

In Mexico, adolescent pregnancies are associated with inadequate prenatal care as well as higher odds of preterm delivery and low birth weight. Youngest adolescents (10-14 years) have the highest probability of adverse outcomes. Adequate prenatal care may help partially mitigate disparities in poor perinatal outcomes.

From Watching to Calling: Linking Variations in an Entertainment-Education Storyline with Calls to a Health Hotline

Substantial gaps exist in the theoretical conceptualization and practical development of entertainment-education, as studies often fail to account for the ways in which intrinsic message characteristics influence subsequent behavior. These gaps served as the impetus for an international collaborative project that evaluated Vencer el Miedo ("Overcome the Fear"), a Spanish-language program that aired in Mexico from January to March 2020. The telenovela was produced with the aim of improving sexual and reproductive health knowledge and behaviors by modeling effective ways to discuss and negotiate safer sex practices. The show was accompanied by a telephone hotline called OrientaSEX operated by professional counselors from MEXFAM, Planned Parenthood's Mexican affiliate. Utilizing an interrupted time series analysis of calls made to OrientaSEX (N = 11,878) and focusing on changes in the volume of calls and the identity of callers following key moments in the storyline, the findings support the central role played by transitional characters and their similarity to audience members. Implications of these results for the theory and practice of entertainment-education are discussed.

Risk factors for adverse pregnancy outcomes in Chinese women: a meta-analysis

Objective

This study examined the associated risk factors of adverse pregnancy outcomes among Chinese females and furnished some fundamental principles and recommendations for enhanced prevention of adverse pregnancy and preservation of women's well-being.

Methods

A systematic review was conducted by retrieving the MEDLINE (The National Library of Medicine), Embase, PubMed, and Cochrane databases. The relevant risk factors for adverse pregnancy in Chinese women were retrieved from May 2017 to April 2023. Use Review Manager for data analysis. Calculate the merge effect based on data attributes using mean difference (MD) or odds ratio (or) and 95% confidence interval (CI). The meta-analysis was registered at INPLASY (International Platform of Registered Systematic Review and Meta-analysis Protocols, 202340090).

Results

A total of 15 articles were included, with a total of 946,818 Chinese pregnant women. Moreover, all the literature was scored by the NOS (Newcastle-Ottawa Scale), and all literatures were ≥7 points, which were evaluated as high quality. There are seven risk factors related to adverse pregnancy in Chinese women: parity, pregnancy frequency, education level, smoking, gestational diabetes, gestational weeks, and age. Moreover, the main risk factors for adverse pregnancy are pregnancy frequency, education level, gestational diabetes mellitus, and age.

Conclusion

The pregnancy frequency, education level, gestational diabetes mellitus, and age were significantly associated with the adverse pregnancy in Chinese women, whereas gestational weeks, smoking, and parity had no significant effect on adverse pregnancy.

The Role of Effective Knowledge on Contraceptive Methods Use in the Replication of Mother-Daughter Adolescent Pregnancy in Mexico

An important gap in the literature is the analysis of the role of effective knowledge concerning use of contraceptive methods in the intergenerational reproduction of adolescent pregnancy in low- and middle-income countries. Using data from the 2014 Mexico National Survey of Demographic Dynamics, we conducted a retrospective cohort and complete case analysis of women aged ≤ 19 years cohabitating with their mothers and who self-reported having had sexual intercourse at the moment of the survey (n = 5143). We estimated instrumental variable probit models (IV-probit) to assess the association between effective knowledge concerning the use of contraceptive methods and adolescent pregnancy. We stratified our models according to parental history of adolescent pregnancy. Adolescent pregnancy prevalence in our sample was 58.7%. The IV-probit model showed that mothers with a history of adolescent pregnancy were 12.1 percentage points more likely to have daughters who experience adolescent pregnancy. In addition, daughters with effective knowledge concerning the use of contraceptive methods were 1.3 percentage points less likely to experience an adolescent pregnancy. Our findings carry relevant implications for policies seeking to reduce adolescent pregnancy. They highlight the need for policies and programs that tackle the intergenerational transmission of sexual and reproductive behaviors by increasing the information available to adolescents and enhancing their effective knowledge about the use of contraceptive methods. Identifying population groups at higher risk of adolescent pregnancy can contribute to the design of successful reproductive health policies in Mexico and other low- and middle-income countries.
