Multilevel prenatal socioeconomic predictors of Mexican American children's cardiometabolic health in preschool and school age.

OBJECTIVE: Using a life course perspective, this longitudinal study examines the extent to which prenatal family- and neighborhood-level socioeconomic factors influence the cardiometabolic health of low-income Mexican American children. It was hypothesized that prenatal maternal residence in a more economically disadvantaged neighborhood and more family-level economic hardship would each be associated with higher adiposity and blood pressure (BP) at child age 4.5 years, and higher adiposity, BP, inflammation and a less healthy lipid profile at child age 7.5 years. METHOD: The sample consisted of 322 low-income, Mexican American mother-child dyads, 181 of whom completed the 7.5-year laboratory visit. Using maternal prenatal residence and U.S. census data, neighborhood concentrated disadvantage index was computed. RESULTS: Higher prenatal neighborhood concentrated disadvantage predicted higher 4.5-year adiposity in children, which, in turn, predicted higher adiposity, BP, and inflammation, and less healthy lipid profile (higher triglycerides, lower high-density lipoprotein cholesterol) at 7.5 years. Higher child 4.5-year BP was concurrently associated with higher adiposity and predicted higher 7.5-year BP. CONCLUSIONS: Extending previous work with this sample, the current study found associations between cardiometabolic risk indicators as early as preschool among Mexican American children. Furthermore, this study builds on existing literature by expanding our understanding of the effect of prenatal neighborhood concentrated disadvantage on cardiometabolic phenotypes during early childhood.

Discrimination and Depressive Symptoms Among Mexican American Women: Exploring Multilevel Sociocultural Moderators.

Relative to empirical studies on risk factors, less research has focused on culturally based protective factors that reduce the impact of discrimination on mental health. The current prospective study evaluated two potential moderators of the effect of discrimination on depressive symptoms among Mexican American women: individually held familism values and neighborhood cultural cohesion. Mexican-origin women in the United States (N = 322; mean age = 27.8 years; 86% born in Mexico) reported on frequency of discrimination, depressive symptoms, familism, and neighborhood cultural cohesion. Independent models evaluated familism and neighborhood cultural cohesion as moderators of the effect of discrimination on subsequent depressive symptoms. More frequent discrimination predicted higher subsequent depressive symptoms. High familism buffered the harmful effect of discrimination on depressive symptoms, such that more frequent discrimination was associated with higher subsequent depressive symptoms only for women who reported average and low familism. Neighborhood cultural cohesion did not buffer the effect of discrimination on depressive symptoms.

Within-dyad bidirectional relations among maternal depressive symptoms and child behavior problems from infancy through preschool.

Although dyadic theory focuses on the impact of a mother's mental health on her own child and the impact of a child's mental health on their own mother, commonly used statistical approaches are incapable of distinguishing the desired within-dyad processes from between-dyad effects. Using autoregressive latent trajectory modeling with structured residuals, the current study evaluated within-dyad, bidirectional associations between maternal depressive symptoms and child behavior problems from child age 1-4.5 years among a sample of low-income, Mexican American women (N = 322, Mage = 27.8) and their children. Women reported on maternal depressive symptoms and child behavior problems during laboratory visits at child age 1, 1.5, 2, 3, and 4.5 years. Results provide novel evidence of child-driven bidirectional association between maternal depressive symptoms and child behavior problems at the within-dyad level as early as child age 1 year and within-person stability in child behavior problems emerging early in life.

Association of BMI trajectories with cardiometabolic risk among low-income Mexican American children.

BACKGROUND: The aim of this study was to identify distinct trajectories of BMI growth from 2 to 7.5 years and examine their associations with markers of cardiometabolic risk at age 7.5 years among a sample of low-income Mexican American children. METHODS: This longitudinal cohort study recruited 322 mother-child dyads to participate prenatally and at child age 2, 3, 4.5, 6, and 7.5 years. Child height/weight, waist circumference, and blood pressure were assessed at each time point. Blood was collected from child at 7.5 years. RESULTS: Covarying for birthweight, three BMI trajectories were identified: Low-Stable BMI (73% of the sample), High-Stable BMI (5.6% of the sample), and Increasing BMI over time (21.4% of the sample). The High-Stable and Increasing BMI classes had higher waist circumference and systolic blood pressure and lower HDL-c than the Low-Stable BMI class (ps < 0.05). Among children with BMIs below the 85th percentile, 16% had three or more cardiometabolic risk indicators. CONCLUSIONS: BMI classes were consistent with existing literature. For youth, standard medical practice is to examine cardiometabolic risk indicators when BMI is high; however, this practice would miss 16% of youth in our sample who exhibit cardiometabolic risk but do not screen in based on BMI. IMPACT: Research indicates Mexican American youth are at risk for cardiometabolic dysregulation relative to other ethnic groups, yet there is a paucity of longitudinal research. An Increasing BMI and a High-Stable BMI class were associated with larger waist circumference, higher systolic blood pressure, and lower HDL cholesterol than the Low-Stable BMI class. BMI trajectories in childhood predict cardiometabolic risk indicators. As the sole screener for deciding when to test cardiometabolic indicators, BMI alone will miss some children exhibiting cardiometabolic dysregulation.

Longitudinal associations between early child weight gain, parent feeding, child self-regulation, and later child body mass index.

BACKGROUND: Few longitudinal studies have examined associations of child weight trajectories, maternal demandingness and responsiveness during feeding, and child self-regulation. OBJECTIVE: We examined if child weight-for-length trajectories from 6 weeks to 2 years of age were associated with maternal demandingness and responsiveness at child age 3 years old, and if maternal feeding dimensions predicted child BMI trajectories from 4.5 to 7.5 years among Mexican American children from low-income families. Child self-regulation was evaluated as a potential mechanism linking maternal feeding with child BMI. METHOD: Child (N = 322) weight and length/height were assessed at 10 timepoints from 6 weeks through 7.5 years. Mothers completed the Caregiver Feeding Style Questionnaire when the child was 3 years of age. RESULTS: A steeper slope of weight-for-length z scores from 6 weeks to 2 years (indicating more rapid weight gain) was associated with less maternal demands during feeding at 3 years. More maternal demandingness at child age 3 years predicted lower child BMI at 4.5 years, but not trajectories from 4.5 to 7 years. Child self-regulation was not associated with child BMI from 4.5 to 7.5 years. CONCLUSION: The findings highlight how the relationship between mothers and children during feeding can be bidirectional and potentially influenced by the developmental stage.

Patterns of maternal interactive behaviors and dual vocabulary development in Mexican American children.

Children learn the words of their native language(s) from interactions with their caregivers. Although previous research has found that the language children hear during those interactions predicts vocabulary outcomes, few studies have investigated how qualitative features of social interactions work together to affect children's vocabulary development, particularly for underresourced, language minoritized children. This study examined patterns of maternal interactive behaviors during toddlerhood in relation to children's later Spanish and English vocabulary development among 318 low-income, Mexican American families. Five maternal behaviors (acknowledging, elaborating, gaze, vocal appropriateness, and overriding) were coded from video recordings at age 24 months. At 36 and 54 months, child expressive vocabulary was assessed in both English and Spanish. Latent class analysis identified five distinct patterns of maternal interactive behaviors, which differentially supported or compromised child expressive language in English and Spanish. Implications of these findings for better understanding the role of caregiver interactions in dual language vocabulary development are discussed.

Within-mother variability in vagal functioning and concurrent socioemotional dysregulation.

During dyadic interactions, well-regulated autonomic responses may support and be supported by socioemotional regulation, whereas autonomic responses that are inappropriate for the social context may be linked with socioemotional dysregulation. We evaluated women's parasympathetic and socioemotional responses during playful interaction with their 24-week-old infants, hypothesizing that insufficient or excessive variability in second-by-second vagal functioning would be associated with concurrent socioemotional dysregulation. Among a sample of 322 low-income, Mexican origin mothers (Mage  = 27.8; SD = 6.5 years), variability in second-by-second vagal functioning was indexed by within-mother standard deviation (SD) in respiratory sinus arrhythmia (RSA) during a 5-min unstructured play task. A latent construct of socioemotional dysregulation was identified using factor analyses. Structural equation modeling was used to evaluate linear and quadratic relations between within-mother SD of RSA and concurrent socioemotional dysregulation. Analyses revealed a positively accelerated relationship between within-mother SD of RSA and concurrent maternal socioemotional dysregulation during play with her infant. Within-mother SD of RSA during a non-interactive baseline task was not related to maternal dysregulation. The results illustrate mothers' dynamic autonomic and socioemotional responses are intertwined during real-time interactions with her infant and lend support for the discriminant validity of within-mother SD of RSA during free play.

Pathways to Maternal and Child Well-Being: Stability and Transaction across Toddlerhood.

OBJECTIVE: This study examines the development of minor parenting stress, parenting satisfaction, and dyadic dysregulation across early childhood and evaluates their roles in predicting maternal and child well-being one year later. DESIGN: Data was collected from 322 low-income, Mexican American mother-child dyads at child ages 12, 18, 24, and 36 months. Mothers responded to questionnaires during structured interviews, and mother-child dyadic interactions were observed during structured teaching tasks and later coded for global displays of emotional, attentional, and behavioral dysregulation. RESULTS: Cross-lag path analyses revealed negative concurrent relations between minor parenting stress and parenting satisfaction at every time point and stability in constructs across time. Parenting stress predicted greater subsequent dyadic dysregulation. Greater dyadic dysregulation and stress related to parenting predicted more maternal depressive symptoms and child behavior problems, whereas greater parenting satisfaction predicted less maternal depressive symptoms and child behavior problems. CONCLUSION: In this minority at-risk population, there was substantial stability in and a lack of transactional relations between minor parenting stresses, parenting satisfaction, and dyadic dysregulation across toddlerhood. These factors are important determinants of maternal and child well-being, with minor parenting stress emerging as particularly powerful.

A prenatal programming perspective on the intergenerational transmission of maternal adverse childhood experiences to offspring health problems.

Decades of research indicate that individuals exposed to childhood adversity are at risk for poor physical and mental health across their life span. More recently, intergenerational transmission of trauma and prenatal programming frameworks suggest an even longer reach for adverse childhood experiences (ACEs), with consequences that extend to subsequent generations. Beyond the individual-level consequences typically observed by empirical studies of ACEs, mothers' experiences of early adversity may also compromise the maternal-child dyadic relationship. We propose a conceptual model whereby mothers' ACEs impact maternal-infant dyadic functioning and later biobehavioral health outcomes through heightened perinatal psychosocial risk. We provide support for the proposed paths and mechanistic processes in our model with data drawn from Las Madres Nuevas, a longitudinal study of low-income Mexican-origin families who participated in a series of home and laboratory visits from the prenatal period through early childhood. Higher ACEs exposure among Las Madres Nuevas participants was associated with numerous perinatal psychosocial risk factors, which predicted poorer mother-infant dyadic functioning. Compromised dyadic functioning during infancy was associated with later maternal mental health and child behavior problems. We conclude with discussion of prevention and treatment strategies that can buffer against proposed risk pathways, including perinatal assessment of maternal ACEs and psychosocial risk, perinatal treatment of maternal distress, and mother-infant therapy in the postpartum period. It is our hope that the proposed conceptual model will serve as a guide for future research to examine the lasting consequences of childhood adversities within and across generations among high-risk populations.

Test of variables of attention performance among ADHD children with credible vs. non-credible PVT performance.

The assessment of effort is a crucial step in the evaluation of children and adolescents who present with symptoms of an Attention-Deficit/Hyperactivity Disorder (ADHD). Studies with adults have found that a large percentage of individuals claiming to have ADHD fail performance validity measures. In children, failure on PVT measures is associated with lower scores on a wide array of neuropsychological measures. The current study examined the performance of 50 children diagnosed with ADHD on the basis of whether they passed (N = 25) versus failed (N = 25) a standalone PVT, on the Test of Variables of Attention (TOVA), the Wisconsin Card Sorting Test - 64 (WCST) and the Tower of London: Drexel (TOL). Subjects who failed one or more PVTs scored significantly below those who passed, on the Omission scores of the TOVA and on several dimensions of the WCST. No significant differences were found on the TOL scores. Specifically, subjects who failed PVTs scored more than two standard deviations below the mean on the first half TOVA Omission errors score, whereas those who passed PVTs scored within the Average range. It is proposed that first half Omission scores on the TOVA may represent an embedded measure of effort.

Patterns of family negativity in the perinatal period: Implications for mental health among Mexican-origin women.

Negativity in the family environment during the perinatal period is likely to have detrimental effects on maternal well-being, especially among low-income ethnic minority mothers who are at increased risk for experiencing postpartum depressive symptoms. With a sample of 322 Mexican and Mexican American families, this study used latent class growth analysis to identify meaningful subgroups of women based on their perceived family negativity reported prenatally and at 6, 12, 18, and 24 weeks postpartum. A 4-trajectory model of family negativity fit the data well: low-stable (58%), moderate-increasing (26%), high-decreasing (8%), and high-increasing (8%). Higher prenatal depressive symptomatology predicted membership in the moderate-increasing, high-decreasing, and high-increasing trajectories, relative to the low-stable trajectory. Findings suggest substantial heterogeneity in family negativity, identifying three significant growth patterns during the perinatal period with differential implications for maternal depressive symptomatology at 24 weeks and 12 months after delivery.

Mother-infant dyadic dysregulation and postpartum depressive symptoms in low-income Mexican-origin women.

The current study evaluated a mechanistic pathway by which prenatal stress increases the risk of postpartum depressive (PPD) symptoms via observed dyadic emotional, behavioral, and attentional dysregulation and associated cortisol responses during mother-infant interactions. METHODS: Participants included 322 low-income Mexican American mother-infant dyads. Depressive symptoms, economic hardship, and negative life events were assessed at a prenatal visit. Dysregulation in dyadic (mother-infant) interactions and cortisol responses to mother-infant interaction were evaluated at 12 weeks after the birth. Twenty-four weeks after the birth, PPD symptoms were predicted from prenatal stress (negative life events and economic hardship) and prenatal depressive symptoms, mediated through dyadic dysregulation and maternal and infant cortisol responses. RESULTS: More negative life events in the prenatal period predicted more dyadic dysregulation at 12 weeks postpartum. Dyadic dysregulation and economic hardship predicted elevated 12-week infant cortisol total response and reactivity, and higher total infant cortisol response predicted higher maternal PPD symptoms at 24 weeks. Maternal cortisol response was not associated with dyadic dysregulation, either form of prenatal stress, or PPD symptoms. CONCLUSION: The results indicate the salience of early psychosocial processes and mother-infant relationship challenges for subsequent maternal affective well-being.

Developmental Trajectories of Maternal Sensitivity across the First Year of Life: Relations among Emotion Competence and Dyadic Reciprocity.

OBJECTIVE: Maternal sensitivity is a commonly used construct to capture the quality of mother-child interactions, but inconsistencies in conceptualizing and defining maternal sensitivity limit understanding of how sensitive caregiving may be associated with child development. The purposes of this study are to (1) examine and compare the developmental trajectories of individual maternal sensitivity behaviors to that of a global index of sensitivity across the first year of infant life and (2) determine whether differences in trajectories of sensitivity are meaningful for infant emotion competence and dyadic reciprocity at 12 months. DESIGN: A total of 322 low-income, Mexican American mothers and infants were observed during a free play task at 3, 4.5, 6, and 12 months. Observations were coded for 11 distinct behaviors known to compose maternal sensitivity. At 12 months, mother-infant interactions were also coded for dyadic reciprocity, and mothers reported on infant emotion competence. RESULTS: Latent growth models indicated that individual sensitivity behaviors differed from the global index of sensitivity with respect to initial levels and slopes, with increasing (e.g., vocal appropriateness), decreasing (e.g., touch), and stable (e.g., elaboration) trajectories. The individual and global indices of sensitivity differed in prediction of emotion competence and dyadic reciprocity. Trajectories of global and individual indices of maternal sensitivity operated similarly in predicting dyadic reciprocity, with the exception of consistency of style. In contrast, the global index of sensitivity was unrelated to emotion competence, and only initial levels of positive affect emerged as significant predictors of emotion competence. CONCLUSIONS: The findings offer a more nuanced understanding of maternal sensitivity and suggest that component aspects of maternal sensitivity uniquely contribute to child and family competencies.
