RESUMO

Importance: Research on fetal epigenetic programming suggests that the intrauterine environment can have long-term effects on offspring disease susceptibility. Objective: To examine the association between prenatal maternal occupation and child epigenetic age acceleration (EAA) among a farmworker community. Design, Setting, and Participants: This cohort study included participants in the Center for the Health Assessment of Mothers and Children of Salinas, a prospective, Latino, prebirth cohort. Pregnant women were recruited from October 1, 1999, to October 1, 2000, from 6 community clinics in California's Salinas Valley agricultural region. Participants were 18 years or older, English or Spanish speaking, Medicaid eligible, and at 20 weeks' gestation or earlier at enrollment. Mother-child pairs who had blood DNA methylation measured at the ages of 7, 9, and 14 years were included. Data were analyzed from July 2021 to November 2023. Exposures: Prenatal maternal occupation was ascertained through study interviews conducted during prenatal visits and shortly after delivery. Main Outcomes and Measures: Child EAA at 7, 9, and 14 years of age was estimated using DNA methylation-based epigenetic age biomarkers. Three EAA measures were calculated: the Horvath EAA, skin and blood EAA, and intrinsic EAA. Linear mixed-effects models were used to estimate longitudinal associations of prenatal maternal occupation and child EAA, adjusting for confounders and prenatal organophosphate pesticide exposure. Results: Analyses included 290 mother-child pairs (mean [SD] maternal age at delivery, 26.5 [5.2] years; 152 [52.4%] female infants); 254 mothers (87.6%) were born in Mexico, 33 (11.4%) in the US, and 3 (1.0%) in other countries; and 179 families (61.7%) were below the federal poverty line during pregnancy. Mothers reported engaging in several types of work during pregnancy, including agricultural fieldwork (90 [31.0%]), other agricultural work (40 [13.8%]), nonagricultural work (53 [18.3%]), or no work (107 [36.9%]). Children whose mothers worked in agricultural fields during pregnancy had a mean of 0.66 (95% CI, 0.17-1.15) years of greater Horvath EAA, 0.62 (95% CI, 0.31-0.94) years of greater skin and blood EAA, and 0.45 (95% CI, 0.07-0.83) years of greater intrinsic EAA compared with children whose mothers did not work during pregnancy. Conclusions and Relevance: In this cohort study, prenatal maternal agricultural fieldwork was associated with accelerated childhood epigenetic aging independent of organophosphate pesticide exposure. Future research on which factors related to agricultural fieldwork accelerate aging in the next generation can inform targeted prevention programs and policies that protect children's health.

RESUMO

OBJECTIVE: Individuals and families from racial and ethnic groups experience social and economic disadvantage making them vulnerable to the disproportionate impact of the COVID-19 pandemic. This study sought to capture the impacts of Shelter in Place (SIP) across key life domains including family life, education, work, mental health, and coping strategies among a sample of Mexican-origin mothers who were currently engaged in agricultural work, or whose spouses were engaged in agricultural work, and young adults who had a parent working in agriculture. METHOD: During the summer of 2020, while California was under SIP orders, we conducted three virtual focus groups using Zoom(r). We recruited focus group participants from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS), an ongoing, 20-year, longitudinal cohort study of Mexican-origin families in a predominantly agricultural area of California. Three focus groups were conducted with mothers (n = 9), mean age = 48 years, young adult women (n = 8) and young adult men (n = 5), mean age = 18 years, respectively. RESULTS: Mothers reported high levels of stress stemming from fear of Covid-19 infection, work instability and financial concerns, children's schooling, anxiety about an uncertain future, and the demands of caretaking for dependents. Adverse mental health impacts were particularly pronounced among participants experiencing multiple adversities pre-dating the pandemic, including unemployment, single motherhood, and having undocumented family members. For young adults, work instability and varying work hours were also a source of stress because they made it difficult to make decisions about the future, such as whether to attend college or how many classes to take. Families used coping strategies including expressing gratitude, focusing on what's under one's control, familismo, and community engagement to manage mental health challenges during SIP. CONCLUSION: In the event of future pandemics or disasters, particular attention is needed to those who experience unemployment, are undocumented and/or have undocumented family members, and/or are single parents facing economic adversity. During public health emergencies, action at the local, state, and national level is needed to support farmworkers and other vulnerable groups' secondary major stressors stemming from inequities in access to affordable housing, childcare, living wages, healthcare, and other benefits.

RESUMO

OBJECTIVES: The Latino population is one of the largest, most diverse, and fastest-growing demographic groups in the United States. Although Latinos enjoy longer life spans and reduced mortality risk relative to non-Hispanic Whites, they have higher rates of chronic health conditions such as diabetes and dementia and live more of their older years with poor health and disability. Such inequities point to the need for this research focused on examining resiliency strategies and barriers to successful aging among various U.S. Latino subgroups. METHODS: This qualitative study used thematic content analysis to examine resiliency strategies and barriers to successful aging among Mexican immigrant women (n = 40) residing in an underserved agricultural community and entering mid-life (mean = 49 years old). RESULTS: With regards to barriers to successful aging, 3 themes emerged: (1) stressful lifestyle in the United States compared to the participants' home countries; (2) stress from expectations at home; and (3) stress due to work and the various components around work. The following 4 resiliency strategies emerged: (1) family as a motivation for moving forward in life and focusing on the success of children; (2) having a positive mindset; (3) praying to God for strength to overcome obstacles; and (4) self-care. DISCUSSION: Despite experiencing barriers to successful aging, participants practice various resiliency strategies to age successfully. Because many of the barriers identified are related to poverty-related stressors, systemic solutions addressing the social determinants of health are needed.

RESUMO

Several studies have reported immune modulation by organophosphate (OP) pesticides, but the relationship between OP exposure and SARS-CoV-2 infection is yet to be studied. We used two different measures of OP pesticide exposure (urinary biomarkers (N = 154) and residential proximity to OP applications (N = 292)) to examine the association of early-childhood and lifetime exposure to OPs and risk of infection of SARS-CoV-2 using antibody data. Our study population consisted of young adults (ages 18-21 years) from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) Study, a longitudinal cohort of families from a California agricultural region. Urinary biomarkers reflected exposure from in utero to age 5 years. Residential proximity reflected exposures between in utero and age 16 years. SARS-CoV-2 antibodies in blood samples collected between June 2022 and January 2023 were detected via two enzyme linked immunosorbent assays, each designed to bind to different SARS-CoV-2 antigens. We performed logistic regression for each measure of pesticide exposure, adjusting for covariates from demographic data and self-reported questionnaire data. We found increased odds of SARS-CoV-2 infection among participants with higher urinary biomarkers of OPs in utero (OR = 1.94, 95% CI: 0.71, 5,58) and from age 0-5 (OR = 1.90, 95% CI: 0.54, 6.95).

RESUMO

Importance: Earlier puberty is associated with adverse health outcomes, such as mental health issues in adolescence and cardiometabolic diseases in adulthood. Despite rapid growth of the Asian American, Native Hawaiian, and Pacific Islander populations in the US, limited research exists on their pubertal timing, potentially masking health disparities. Objective: To examine pubertal timing among Asian American, Native Hawaiian, and Pacific Islander children and adolescents by disaggregating ethnic subgroups. Design, Setting, and Participants: This retrospective cohort study included Asian American, Native Hawaiian, and Pacific Islander youths aged 5 to 18 years assessed for pubertal development at Kaiser Permanente Northern California, a large, integrated health care delivery system. Follow-up occurred from March 2005, through December 31, 2019. Data were analyzed in October 2023. Exposure: Race and ethnicity, categorized into 11 ethnic subgroups: Asian Indian, Chinese, Filipino, Japanese, Korean, Native Hawaiian and Pacific Islander, Other South Asian, Other Southeast Asian, Vietnamese, multiethnic, and multiracial. Main Outcomes and Measures: Pubertal timing was determined using physician-assessed sexual maturity ratings (SMRs). Outcomes included the median age at transition from SMR 1 (prepubertal) to SMR 2 or higher (pubertal) for onset of genital development (gonadarche) in boys, breast development (thelarche) in girls, and pubic hair development (pubarche) in both boys and girls. Results: In this cohort of 107 325 Asian American, Native Hawaiian, and Pacific Islander children and adolescents (54.61% boys; 12.96% Asian Indian, 22.24% Chinese, 26.46% Filipino, 1.80% Japanese, 1.66% Korean, 1.96% Native Hawaiian and Pacific Islander, 0.86% Other South Asian, 3.26% Other Southeast Asian, 5.99% Vietnamese, 0.74% multiethnic, and 22.05% multiracial), the overall median ages for girls' pubarche and thelarche were 10.98 years (95% CI, 10.96-11.01 years) and 10.13 years (95% CI, 10.11-10.15 years), respectively. For boys' pubarche and gonadarche, median ages were 12.08 years (95% CI, 12.06-12.10 years) and 11.54 years (95% CI, 11.52-11.56 years), respectively. Differences between subgroups with earliest and latest median age at onset were 14 months for girls' pubarche, 8 months for thelarche, 8 months for boys' pubarche, and 4 months for gonadarche. In general, Asian Indian, Native Hawaiian and Pacific Islander, and Other South Asian subgroups had the earliest ages at onset across pubertal markers, while East Asian youths exhibited the latest onset. Restricting to those with healthy body mass index did not substantially change the findings. Conclusions and Relevance: In this cohort study of Asian American, Native Hawaiian, and Pacific Islander children and adolescents, pubertal timing varied considerably across ethnic subgroups. Further investigation is warranted to assess whether these differences contribute to observed health disparities in adulthood, such as type 2 diabetes and cardiovascular diseases.

RESUMO

INTRODUCTION: Maternal adverse childhood experiences have been linked to a variety of negative health outcomes in young children; however, young adults and, specifically, young adult Latinos have been vastly understudied. This study investigates the intergenerational pathway between maternal adverse childhood experiences and behavioral health outcomes of their young adult children, as mediated through young adults' own adverse childhood experiences and maternal depression. METHODS: Structural equation modeling was used to analyze data (in 2023) from mothers and their young adult children (n=398 dyads) enrolled in the Center for the Health Assessment of Mothers and Children of Salinas cohort, a primarily Latino agricultural sample. Maternal and young adult adverse childhood experiences were self-reported retrospectively during a visit at the age of 18 years (2018-2020). Young adult- and maternal-reported internalizing and maternal-reported externalizing behaviors were assessed at the age of 18 years with the Behavior Assessment for Children, second edition. Maternal depression was assessed during a visit at the age of 9 years (2010-2012) using the Center for Epidemiologic Studies Depression Scale. RESULTS: Maternal and young adult adverse childhood experiences were weakly but statistically significantly correlated (r=0.22). Maternal adverse childhood experiences were statistically significantly associated with maternal-reported youth internalizing symptoms (ß=0.29; 95% CI=0.19, 0.38; p<0.001) and externalizing symptoms (ß=0.24; 95% CI=0.14, 0.33; p<0.001) and marginally associated with youth-reported internalizing symptoms (ß=0.08; 95% CI= -0.02, 0.18; p=0.13). Youth adverse childhood experiences and maternal depressive symptomatology mediated the associations between maternal adverse childhood experiences and young adult outcomes. CONCLUSIONS: Findings demonstrate the potential impacts of adversity across generations in Latino immigrant families, an understudied population. Understanding the mechanisms and factors associated with these pathways may lead to strategies that prevent poor mental health outcomes in young adults.

RESUMO

INTRODUCTION: Latinos are the fastest growing aging population in the U.S. However, there has been limited attention to conceptualizing successful aging among Latinos, especially those residing in rural communities. Latinos are the largest racial or ethnic group residing in rural underserved communities and rural Latinos experience significant structural barriers to access the conditions they need to age well. The goal of this study is to make unique contributions to the successful aging literature by describing what successful aging means for middle-aged Latinas residing in a rural community. METHODS: This qualitative paper used inductive thematic content analysis to examine definitions of successful aging among Latina women (n = 40) residing in an underserved agricultural community and entering mid-life (mean = 49 years old; age range 40-64). RESULTS: With regards to definitions of successful aging, four themes emerged: 1) Having good health; 2) maintaining an active lifestyle; 3) the wellbeing of one's children; and 4) being independent. DISCUSSION: Participants' definitions of successful aging aligned to some extent with existing frameworks, specifically related to health and independence. However, middle-aged Latina participants' unique definitions of successful aging also diverged from existing frameworks, especially around the wellbeing of their children and the importance of work as a way of maintaining an active lifestyle. More research is needed to understand the unique social context and circumstances of middle-aged Latinos residing in rural communities and how they influence their aging journeys. This can provide important information for the development of culturally sensitive services, interventions, and policies to help Latinos age well.

RESUMO

Gender inequity is pervasive globally and has severe consequences for health and well-being, particularly for women and girls in Niger. The Reaching Married Adolescents in Niger (RMA) intervention aimed to promote equitable gender norms in order to increase modern contraceptive use and reduce intimate partner violence among married adolescent girls and their husbands in Niger. Using data from a 4-arm factorial cluster randomized control trial of the RMA intervention (2016-2019), the current study assesses effects of the RMA intervention on gender norms among husbands. We used an adjusted hierarchical difference-in-differences linear regression model to assess these effects. The mean score for perceived gender inequitable norms at baseline was 4.1 (n=1,055; range: 0-5). Assignment to the RMA small groups intervention was associated with a 0.62 lower score (95% CI: -1.05, -0.18) relative to controls at follow-up, after adjusting for baseline differences. No significant effects were detected for other intervention arms. As a low-cost, simple, scalable, and transferrable intervention with rigorous evidence of being able to change such gender norms, this community health worker-based small group intervention could be valuable to the field of public health for reducing the negative impact of inequitable gender norms on health and wellbeing in similar settings.

RESUMO

BACKGROUND: Adverse childhood experiences (ACEs) increase the risk of poor health outcomes later in life. Psychosocial stressors may also have intergenerational health effects by which parental ACEs are associated with mental and physical health of children. Epigenetic programming may be one mechanism linking parental ACEs to child health. This study aimed to investigate epigenome-wide associations of maternal preconception ACEs with DNA methylation patterns of children. In the Center for the Health Assessment of Mothers and Children of Salinas study, cord blood DNA methylation was measured using the Illumina HumanMethylation450 BeadChip. Preconception ACEs, which occurred during the mothers' childhoods, were collected using a standard ACE questionnaire including 10 ACE indicators. Maternal ACE exposures were defined in this study as (1) the total number of ACEs; (2) the total number of ACEs categorized as 0, 1-3, and > 4; and (3) individual ACEs. Associations of ACE exposures with differential methylated positions, regions, and CpG modules determined using weighted gene co-expression network analysis were evaluated adjusting for covariates. RESULTS: Data on maternal ACEs and cord blood DNA methylation were available for 196 mother/newborn pairs. One differential methylated position was associated with maternal experience of emotional abuse (cg05486260/FAM135B gene; q value < 0.05). Five differential methylated regions were significantly associated with the total number of ACEs, and 36 unique differential methylated regions were associated with individual ACEs (Sidák p value < 0.05). Fifteen CpG modules were significantly correlated with the total number of ACEs or individual ACEs, of which 8 remained significant in fully adjusted models (p value < 0.05). Significant modules were enriched for pathways related to neurological and immune development and function. CONCLUSIONS: Maternal ACEs prior to conception were associated with cord blood DNA methylation of offspring at birth. Although there was limited overlap between differential methylated regions and CpGs in modules associated with ACE exposures, statistically significant regions and networks were related to genes involved in neurological and immune function. Findings may provide insights to pathways linking psychosocial stressors to health. Further research is needed to understand the relationship between changes in DNA methylation and child health.

RESUMO

Gender norms have been posited to impact intimate partner violence (IPV), but there is scant evidence of the longitudinal association between community-level gender norms and IPV. Using longitudinal data on 3,965 married girls surveyed in India, we fitted mixed-effects ordinal and binary logistic regression models for physical IPV intensity and occurrence of sexual IPV. We found a 26% increase in the odds that women experience frequent physical IPV per one unit increase in greater community-level equitable gender norms. We did not find an association between community-level equitable gender norms and sexual IPV. Findings suggest that the relationship between gender norms and physical and sexual IPV differs, indicating the need for tailored interventions for different types of IPV.

RESUMO

Importance: Understanding how structural racism is associated with adolescent mental health is critical to advance health equity. Objective: To assess associations between neighborhood privilege, measured by the Index of Concentration at the Extremes (ICE) and adolescent depressive symptoms, suicidality, and related racial and ethnic disparities. Design, Setting, and Participants: This was a retrospective cohort study using electronic health records of adolescents aged 12 to 16 years who attended well-teen visits between 2017 and 2021. Kaiser Permanente Northern California is an integrated health care delivery system serving 4.6 million members. The cohort included 34 252 individuals born singleton at an affiliated facility from January 1, 2005, to December 31, 2009, and who had completed at least 1 mental health screener during a well-teen visit by November 23, 2021. Exposures: American Community Survey 2016 to 2021 5-year estimates were used to calculate ICE scores for adolescents' residential census tract at ages 10 to 11. Three ICE measures were used as proxies of structural racism: racial privilege (ICE-race and ethnicity; hereinafter ICE-race), economic privilege (ICE-income), and combined economic and racial privilege (ICE-income plus race and ethnicity; herinafter ICE-income plus race). ICE scores were categorized into quintiles based on California statewide distributions. Main Outcomes and Measures: Depressive symptoms and suicidality were assessed through self-report screeners during well-teen visits. Depressive symptoms were considered to be present if patients had a score on the Patient Health Questionnaire-2 of 3 or higher (the tool uses a Likert scale to determine the frequency [0 = not at all; 3 = nearly every day] that they had depressed mood and lack of pleasure in usual activities in the past 2 weeks; responses were summed and dichotomized). Results: Analyses included 34 252 adolescents (12-16 years of age; mean [SD] age, 13.7 [0.8] years; 17 557 [51.3%] male, 7284 [21.3%] Asian or Pacific Islander, 2587 [7.6%] Black], 9061 [26.5%] Hispanic, 75 [0.2%] American Indian or Indigenous, 12 176 [35.5%] White, and 3069 [9%] other or unknown). Risks of depressive symptoms and suicidality generally increased with each level of declining neighborhood privilege. Adjusted risk ratios comparing adolescents from neighborhoods with the least to most racial and economic privilege were 1.37 (95% CI, 1.20-1.55) for depressive symptoms and 1.59 (95% CI, 1.23-2.05) for suicidality. Racial disparities between Black and White youth and Hispanic and White youth decreased after adjusting for each ICE measure, and became nonsignificant in models adjusting for ICE-race and ICE-income plus race. Conclusions and Relevance: In this cohort study, lower neighborhood privilege was associated with greater risks of adolescent depressive symptoms and suicidality. Furthermore, adjusting for neighborhood privilege reduced mental health disparities affecting Black and Hispanic adolescents. These findings suggest that efforts to promote equity in adolescent mental health should extend beyond the clinical setting and consider the inequitable neighborhood contexts that are shaped by structural racism.

RESUMO

BACKGROUND: The field of violence prevention research is unequivocal that interventions must target contextual factors, like social norms, to reduce gender-based violence. Limited research, however, on the social norms contributing to intimate partner violence or reproductive coercion exists. One of the driving factors is lack of measurement tools to accurately assess social norms. METHODS: Using an item response modelling approach, this study psychometrically assesses the reliability and validity of a social norms measure of the acceptability of intimate partner violence to exert control over wife agency, sexuality, and reproductive autonomy with data from a population-based sample of married adolescent girls (ages 13-18) and their husbands in rural Niger (n = 559 husband-wife dyads) collected in 2019. RESULTS: A two-dimensional Partial Credit Model for polytomous items was fit, showing evidence of reliability and validity. Higher scores on the "challenging husband authority" dimension were statistically associated with husband perpetration of intimate partner violence. CONCLUSIONS: This brief scale is a short (5 items), practical measure with strong reliability and validity evidence. This scale can help identify populations with high-need for social norms-focused IPV prevention and to help measure the impact of such efforts.


Long-term prevention of gender-based violence, like intimate partner violence and reproductive coercion, requires efforts to change the social environment that facilitates violence against women, yet limited research is available on how to change social environments. One reason is that there are few tools to accurately measure social environments, including social norms, which are the unspoken rules about what behavior is acceptable and what behavior is not. The present research assessed a new social norms measurement tool on the acceptability of intimate partner violence to exert control over wife agency, sexuality, and reproductive autonomy using data from a population-based sample of married adolescents and their husbands in rural Niger (n = 559 husband-wife dyads) collected in 2019. We found that this scale had strong reliability and validity, and that the group of questions about challenging husband authority were related to husband perpetration of intimate partner violence against his wife. This brief scale is a short (5 questions), practical measure with strong reliability and validity evidence that can help identify populations with high-need for social norms-focused prevention and to help measure the impact of such efforts. This evidence strengthens the current set of measurement tools on social norms available to researchers and practitioners.

RESUMO

BACKGROUND: We previously reported associations of prenatal exposure to organophosphate (OP) pesticides with poorer neurodevelopment in early childhood and at school age, including poorer cognitive function and more behavioral problems, in the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS), a birth cohort study in an agriculture community. OBJECTIVE: We investigated the extent to which early-life exposure to OP pesticides is associated with behavioral problems, including mental health, in youth during adolescence and early adulthood. METHODS: We measured urinary dialkylphosphates (DAPs), nonspecific OP metabolites, in urine samples collected from mothers twice during pregnancy (13 and 26 wk) and at five different times in their children (ages 6 months to 5 y). We assessed maternal report and youth report of externalizing and internalizing behavior problems using the Behavior Assessment System for Children, 2nd edition (BASC-2), when the youth were ages 14, 16, and 18 y. Because there was evidence of nonlinearity, we estimated associations across quartiles of DAPs and modeled repeated outcome measures using generalized estimating equations. RESULTS: There were 335 youths with prenatal maternal DAP measures and 14-. 16-, or 18-y BASC-2 scores. Prenatal maternal DAP concentrations (specific gravity-adjusted median, Q1-Q3=159.4, 78.7-350.4 nmol/L) were associated with higher T-scores (more behavior problems) from maternal report, including more hyperactivity [fourth vs. first quartile of exposure ß=2.32; 95% confidence interval (CI): 0.18, 4.45], aggression (ß=1.90; 95% CI: 0.15, 3.66), attention problems (ß=2.78; 95% CI: 0.26, 5.30), and depression (ß=2.66; 95% CI: 0.08, 5.24). Associations with youth report of externalizing problems were null, and associations with depression were suggestive (fourth vs. first quartile of exposure ß=2.15; 95% CI: -0.36, 4.67). Childhood DAP metabolites were not associated with behavioral problems. DISCUSSION: We found associations of prenatal, but not childhood, urinary DAP concentrations with adolescent/young adult externalizing and internalizing behavior problems. These findings are consistent with prior associations we have reported with neurodevelopmental outcomes measured earlier in childhood in CHAMACOS participants and suggests that prenatal exposure to OP pesticides may have lasting effects on the behavioral health of youth as they mature into adulthood, including their mental health. https://doi.org/10.1289/EHP11380.

RESUMO

Purpose: Children of mothers with prenatal depression have elevated risk for depression later in life. Pregnant women are hesitant to use antidepressants due to fear of adverse fetal effects. To inform prevention, this study examined associations between maternal prenatal depression and antidepressant use, and adolescent depressive symptoms and suicidality. Patients and Methods: Prospective data from 74,695 mother-adolescent dyads from the Kaiser Permanente Northern California integrated healthcare delivery system were used. Three prenatal exposure groups were examined: maternal depression and antidepressants (Med); depression and no antidepressants (No-Med); neither depression nor antidepressants (NDNM). Adolescent depressive symptoms (Patient Health Questionnaire-2 score ≥3) and suicidality were assessed for 12- to 18-year-olds. Associations were analyzed using mixed effects logistic regression, adjusted for confounders. Results: Maternal prenatal depression was associated with higher odds of adolescent depressive symptoms (Med odds ratio [OR]: 1.50, 95% confidence interval [CI]: 1.23-1.84; No-Med OR: 1.59, CI: 1.34-1.88) and suicidality (Med OR: 2.36, CI: 1.67-3.34; No-Med OR: 1.54, CI: 1.10-2.14) compared to no prenatal depression (NDNM). Adolescents exposed to prenatal depression and antidepressants were not at greater odds of depressive symptoms (Med OR: 0.95, CI: 0.74-1.21) compared to those not exposed to antidepressants (No-Med). However, they showed non-significant but greater odds of suicidality (Med OR: 1.54, CI: 0.99-2.39). Conclusion: Our findings suggest that maternal prenatal depression is associated with adolescent depressive symptoms and suicidality, and that exposure to antidepressants in utero does not increase risk of depressive symptoms, specifically. While not statistically significant, the increased odds of suicidality among adolescents exposed to antidepressants suggest a possible association; however, further investigation is needed. After replication, the findings of this study may inform shared clinical decision-making when considering options regarding antidepressant use for the treatment of maternal prenatal depression.

RESUMO

BACKGROUND: Phthalates, a group of pervasive endocrine-disrupting chemicals found in plastics and personal care products, have been associated with a wide range of developmental and health outcomes. However, their impact on biomarkers of aging has not been characterized. We tested associations between prenatal exposure to 11 phthalate metabolites on epigenetic aging in children at birth, 7, 9, and 14 years of age. We hypothesized that prenatal phthalate exposure will be associated with epigenetic age acceleration measures at birth and in early childhood, with patterns dependent on sex and timing of DNAm measurement. METHODS: Among 385 mother-child pairs from the CHAMACOS cohort, we measured DNAm at birth, 7, 9, and 14 years of age, and utilized adjusted linear regression to assess the association between prenatal phthalate exposure and Bohlin's Gestational Age Acceleration (GAA) at birth and Intrinsic Epigenetic Age Acceleration (IEAA) throughout childhood. Additionally, quantile g-computation was utilized to assess the effect of the phthalate mixture on GAA at birth and IEAA throughout childhood. RESULTS: We found a negative association between prenatal di (2-ethylhexyl) phthalate (DEHP) exposure and IEAA among males at age 7 (-0.62 years; 95% CI:-1.06 to -0.18), and a marginal negative association between the whole phthalate mixture and GAA among males at birth (-1.54 days, 95% CI: -2.79 to -0.28), while most other associations were nonsignificant. CONCLUSIONS: Our results suggest that prenatal exposure to certain phthalates is associated with epigenetic aging in children. Additionally, our findings suggest that the influence of prenatal exposures on epigenetic age may only manifest during specific periods of child development, and studies relying on DNAm measurements solely from cord blood or single time points may overlook potential relationships.

RESUMO

PURPOSE: Youth are vulnerable to poor mental health outcomes during emerging adulthood. This study examined COVID-19 pandemic effects among young Latino adults and changes in anxiety and depressive symptoms. METHODS: Using data from 309 individuals, predominantly of Mexican origin, we examined anxiety and depressive symptoms (before and during COVID) to determine whether mental health worsened during this period. We also examined associations between specific pandemic-related stressors and mental health. Analyses used paired T-tests and linear regressions. Participant sex was included as a moderator. We corrected for multiple comparisons using the Benjamini-Hochberg method. RESULTS: During the 2-year time period, depressive symptoms increased while anxiety symptoms decreased. There were no significant stressor by sex interactions; however, exploratory analyses signaled that pandemic-related stressors had stronger mental health effects for young women. DISCUSSION: Young adults' depressive and anxiety symptoms changed during the pandemic, and pandemic-related stressors were associated with increases in mental health symptoms.

RESUMO

OBJECTIVE: Describe the prevalence of considering, wanting, and not obtaining a wanted abortion among a nationally representative sample of 15-44 year olds in the United States who had ever been pregnant. STUDY DESIGN: We analyzed data from ever-pregnant respondents (unweighted n = 1789) from a larger online survey about contraceptive access using the nationally representative AmeriSpeak panel. Among those not obtaining wanted abortions, weighted frequencies for sociodemographic characteristics and reasons for not getting the abortion are presented. RESULTS: Nearly 6% of the full sample reported having wanted an abortion they did not obtain. In open-ended responses, respondents most frequently reported individual reasons (43.8%) for not getting an abortion (e.g., changing their mind; personal opposition) and financial, logistical, or informational barriers (24.7%) likely related to policy. A quarter (24.1%) of the sample reported a past abortion. Among those who reported no past abortions, about one-fifth had considered abortion in the past, and 6.8% had wanted or needed one. Among those reporting no prior abortions who had considered abortion, only a third (34.3%) also report ever wanting or needing one. CONCLUSIONS: This study begins to quantify the experience, even before the Supreme Court's 2022 decision in Dobbs v. Jackson Women's Health Organization, of being unable to obtain a wanted abortion. Additionally, findings suggest that people in a national sample will answer questions about whether and why they did not obtain a wanted abortion. IMPLICATIONS: This study provides the first known national estimates of lifetime history of not getting a wanted abortion. Survey questions can be used for future research. Prospective and ongoing measurement of the inability to get a wanted abortion could be one part of documenting the effects of Dobbs on abortion access.

RESUMO

OBJECTIVE: To assess the magnitude of racial-ethnic disparities in pandemic-related social stressors and examine frontline work's moderating relationship on these stressors. DATA SOURCES: Employed Californians' responses to the Institute for Governmental Studies (IGS) poll from April 16-20, 2020, were analyzed. The Pandemic Stressor Scale (PSS) assessed the extent to which respondents experienced or anticipated problems resulting from the inability to pay for basic necessities, job instability, lacking paid sick leave, unavailability of childcare, and reduced wages or work hours due to COVID-19. STUDY DESIGN: Mixed-effects generalized linear models estimated (1) racial-ethnic disparities in pandemic stressors among workers during the first COVID-19 surge, adjusting for covariates, and (2) tested the interaction between race-ethnicity and frontline worker status, which includes a subset of essential workers who must perform their job on-site, to assess differential associations of frontline work by race-ethnicity. DATA COLLECTION: The IGS poll data from employed workers (n = 4795) were linked to the 2018 Centers for Disease Control and Prevention Social Vulnerability Index at the zip code level (N = 1068). PRINCIPAL FINDINGS: The average PSS score was 37.34 (SD = 30.49). Whites had the lowest PSS score (29.88, SD = 26.52), and Latinxs had the highest (50.74, SD = 32.61). In adjusted analyses, Black frontline workers reported more pandemic-related stressors than White frontline workers (PSS = 47.73 vs. 36.96, p < 0.001). Latinxs reported more pandemic stressors irrespective of frontline worker status. However, the 5.09-point difference between Latinx frontline and non-frontline workers was not statistically different from the 4.6-point disparity between White frontline and non-frontline workers. CONCLUSION: Latinx workers and Black frontline workers disproportionately reported pandemic-related stressors. To reduce stress on frontline workers during crises, worker protections like paid sick leave, universal access to childcare, and improved job security are needed, particularly for those disproportionately affected by structural inequities, such as racially minoritized populations.

RESUMO

OBJECTIVE: To determine if the ages at pubertal milestones are associated with the prevalence of adolescent migraine. BACKGROUND: Migraine headaches are a common disease in adolescent girls. Past studies have evaluated the relationship between age of onset of menarche and migraine headache, but none have studied earlier pubertal milestones such as thelarche and pubarche. METHODS: In this cross-sectional study, a previously validated questionnaire was administered to girls (15-18 years) in Breast Cancer and the Environment Research Program puberty cohort to ascertain if they met criteria for migraine over the past year. Ages of pubertal development were ascertained by serial examinations beginning at 6-8 years of age and ending in late puberty. Logistic regression analyses determined if age of onset of each pubertal milestone (thelarche, pubarche, menarche separately) was associated with adolescent migraine after adjusting for other risk factors. RESULTS: Of 761girls, 222 (29.2%) met the criteria for migraine. Later thelarche was associated with a lower odds of adolescent migraine (OR 0.83; 95% CI 0.72-0.97, p = 0.019). In models further adjusted for BASC-2 internalizing problems (n = 490), both later thelarche (OR 0.78; 95% CI 0.64-0.96, p = 0.016) and later menarche (OR 0.81; 95%CI 0.67-0.98, p = 0.026) were associated with a lower migraine prevalence. Internalizing problems (OR 1.05; 95% CI 1.03-1.07) externalizing problems (OR 1.05; 95% CI 1.02-1.07) and behavioral symptoms (OR 1.05; 95% CI 1.03-1.08) were associated with increased prevalence of migraine in separate models. CONCLUSIONS: Age of onset of thelarche and menarche, and internalizing, externalizing, and behavioral symptoms were all associated with adolescent migraine.
