Resource dilution in maternal feeding practices after birth of a secondborn.

Firstborn children have higher prevalence of obesity than secondborn siblings. The birth of a sibling typically results in resource dilution when mothers begin to divide their time and attention between two children. This mixed-methods analysis applies the family systems process of resource dilution to test the hypothesis that characteristics of the secondborn impact how parents feed the firstborn. Participants (n = 76) were mothers of consecutively born firstborn and secondborn siblings who participated in the INSIGHT trial and an observational cohort. Quantitative analyses involved multilevel models to test if characteristics of secondborns (temperament at 16 weeks, appetite at 28 weeks) were associated with maternal feeding practices of firstborns (structure and control-based feeding) at 1, 2, and 3 years, adjusting for firstborn child characteristics. A purposive subsample (n = 30) of mothers participated in semi-structured interviews to contextualize potential sibling influences on maternal feeding practices during infancy and toddlerhood. Quantitative data showed secondborn temperament and appetite were associated with how mothers fed their firstborn. Qualitative data explained maternal feeding practices in three primary ways: 1) Mothers explained shifting predictable meal and snack routines after birth of the secondborn, but did not perceive sibling characteristics as the source; 2) Family chaos following the secondborn's birth led to "survival mode" in feeding; and 3) Social support was protective against feeding resource dilution. The family systems process of resource dilution is a focus for future research and support for families during key transitions and a direction for efforts to reduce risk for child obesity.

A mixed methods study of siblings' roles in maternal feeding practices in early childhood: an application of the learning from experience process.

BACKGROUND: Firstborn children have higher rates of obesity compared to secondborns, perhaps due, in part, to differential feeding practices. Despite the centrality of siblings in family life and potential for influence, almost nothing is known about the role of siblings in parent feeding practices in early childhood. METHODS: Participants (n = 117) were mothers of consecutively born siblings. Firstborns participated in an RCT that compared a responsive parenting intervention designed for primary prevention of obesity against a safety control. Secondborns participated in an observational cohort. Multilevel models tested whether and how firstborn characteristics (temperament, appetite, rapid weight gain) at 16 weeks and 1 year were associated maternal feeding practices of secondborns in infancy at 16 weeks, 28 weeks, and 1 year (food to soothe) and at ages 1, 2, and 3 years (structure-and control-based feeding practices). A purposive subsample (n = 30) of mothers also participated in semi-structured interviews to further illuminate potential sibling influences on maternal feeding practices during infancy and toddlerhood. RESULTS: Firstborn characteristics did not predict secondborn feeding in infancy (all ps > 0.05). Firstborn negative affect, however, predicted mothers' less consistent mealtime routines (b (SE) = - 0.27 (0.09); p = 0.005) and more pressure (b (SE) = 0.38 (0.12); p = 0.001). Firstborn appetite predicted mothers' less frequent use of food to soothe (b (SE) = - 0.16 (0.07); p = 0.02) when secondborns were toddlers. Firstborn surgency, regulation, and rapid weight gain, however, did not predict secondborn feeding practices during toddlerhood (all ps > 0.05). Interviews with mothers revealed three ways that maternal experiences with firstborns informed feeding practices of secondborns: 1) Use of feeding practices with secondborn that worked for the firstborn; 2) Confidence came from firstborn feeding experiences making secondborn feeding less anxiety-provoking; and 3) Additional experiences with firstborn and other factors that contributed to secondborn feeding practices. CONCLUSIONS: Some firstborn characteristics and maternal experiences with firstborns as well as maternal psychosocial factors may have implications for mothers' feeding practices with secondborns. Together, these mixed methods findings may inform future research and family-based interventions focused on maternal feeding of siblings in early childhood.

Daily links between Latinx siblings' relationship qualities and mood.

This study examined daily links between sibling warmth and negativity and positive and negative mood in middle childhood and the moderating role of enculturation. Participants were 326 Latinx children from 163 families in the United States (Mage  = 10.63 and 8.58 years for older and younger siblings, 48.5% female, 89.3% Mexican-origin). Children reported their days' experiences during seven nightly phone interviews conducted in 2018-2019. Multilevel analyses revealed within-person, positive associations between daily sibling warmth and positive mood ( OR = 1.81 , 95 % CI = [ 1.25 , 2.62 ] ) , and sibling negativity and negative mood ( OR = 3.21 , 95 % CI = [ 2.12 , 4.86 ] ) . Moreover, for more enculturated children, odds of positive mood were lower on days when they experienced more sibling negativity than usual. Findings document the significance of Latinx children's daily sibling experiences.

Weight Concerns in Black Youth: The Role of Body Mass Index, Gender, and Sociocultural Factors.

Weight concerns are prevalent among Black adolescents and have negative ramifications for well-being. We examined racial identity and racial socialization as potential sociocultural resources that might mitigate the development of weight concerns among Black adolescents, and we evaluated gender differences in these links. Participants were 132 Black youth (45% female; M age = 14.33 years at Time 1) who completed two annual home interviews. Results revealed that for adolescents with high (but not low) body mass indices (BMI), racial identity may be protective against developing weight concerns. Further, fathers' (but not mothers') racial socialization was protective against weight concerns for girls with high BMI. Findings highlight the importance of sociocultural contexts toward refining theory and advancing evidence-based practice.

Religious Coping and Gender Moderate Trajectories of Marital Love among Black Couples.

An increasing body of work documents the roles of religion and spirituality in Black American marriages. We built on this research to examine religious coping as a potential cultural resource for Black marriages using a dyadic analytic approach with longitudinal data. Specifically, we investigated the effects of positive (i.e., sense of spiritual connectedness) and negative (i.e., spiritual tension or struggle) religious coping on trajectories of marital love reported by wives and husbands in 161 Black, married, mixed-gender couples, and we tested the potential moderating role of spouse gender. At baseline, spouses reported on their religious coping, and they rated their marital love at baseline and during two additional home interviews conducted annually. Data were analyzed using growth curve modeling within an Actor-Partner Interdependence Modeling framework. Husbands who reported more positive religious coping at baseline exhibited relatively high and stable marital love over time, whereas those who reported less positive religious coping reported less love at baseline and exhibited declines in love over time. Wives who reported less negative religious coping at baseline were higher in marital love initially but showed declines over time, whereas those who reported more negative religious coping at baseline were lower in marital love initially but showed increases in love over time. Results highlight the importance of further research on the role of religion and religious coping in Black couples' marital experiences and suggest differential roles of positive and negative religious coping for men's and women's marital love. Clinical and policy implications are discussed.

Cada vez más investigaciones documentan los papeles que desempeñan la religión y la espiritualidad en los matrimonios afroestadounidenses. Utilizamos estas investigaciones como punto de partida para analizar el afrontamiento religioso como posible recurso cultural para los matrimonios de color usando un método analítico diádico con datos longitudinales. Específicamente, investigamos los efectos del afrontamiento religioso positivo (p. ej.: la sensación de conexión espiritual) y negativo (p. ej.: la tensión o la lucha espiritual) en las trayectorias del amor conyugal informado por esposas y esposos en 161 parejas de color, casadas y de género mixto, y evaluamos el posible rol moderador del género del cónyuge. En el momento basal, los cónyuges informaron sobre su afrontamiento religioso y calificaron su amor conyugal en el momento basal y durante otras dos entrevistas en el hogar realizadas anualmente. Se analizaron los datos usando el modelo de curva de crecimiento dentro de un marco del modelo de interdependencia actor-pareja. Los esposos que informaron un afrontamiento religioso más positivo en el momento basal demostraron un amor conyugal relativamente alto y estable con el paso del tiempo, mientras que los que informaron un afrontamiento menos positivo indicaron menos amor en el momento basal y demostraron disminuciones en el amor con el paso del tiempo. Las esposas que informaron menos afrontamiento religioso negativo en el momento basal tuvieron un amor conyugal más alto inicialmente, pero demostraron disminuciones con el paso del tiempo, mientras que aquellas que informaron un afrontamiento religioso más negativo en el momento basal tuvieron menos amor conyugal inicialmente, pero demostraron aumentos del amor con el paso del tiempo. Los resultados destacan la importancia de realizar más investigaciones sobre el papel que desempeñan la religión y el afrontamiento religioso en las experiencias conyugales de las parejas de color, y sugieren que el afrontamiento religioso positivo y negativo desempeña distintos roles en el amor conyugal de los hombres y las mujeres. Se comentan las implicancias clínicas y políticas.

The developmental course of the link between weight concerns and cigarette use across adolescence: Differences by gender.

OBJECTIVE: This study aimed to illuminate developmental changes and gender differences in the link between weight concerns and cigarette use across adolescence. Specifically, we examined whether and how the strength of the association between weight concerns and cigarette use changed across adolescence, and whether patterns of association differed between boys and girls. METHOD: Participants were 397 predominately White adolescents ages 11-18 years (50.5% female) from a longitudinal observational study conducted in the United States. RESULTS: Time-varying effect modeling revealed that even after adjusting for BMI, the association between weight concerns and cigarette use was positive and significant for girls from age 11.3 to 15.9, with the strongest association at 12.7 years. For boys, this association was non-significant throughout adolescence. DISCUSSION: Results suggest a sensitive period in early- to mid-adolescence during which girls with weight concerns may be at heightened risk for cigarette use. Findings have implications for the developmental timing of interventions to prevent cigarette use and weight concerns and suggest that tailored interventions for girls may be warranted.

Implications of Mexican-origin youth's work experiences for relationships with fathers.

OBJECTIVE: To illuminate family implications of youth's work, we examined longitudinal links between the work experiences of Mexican-origin youth in late adolescence and young adulthood and father-youth relationships. METHOD: Using data from 187 Mexican-origin youth and their employed fathers, we tested youth's (52.4% female; Mage = 19.64, SD = 1.78) work hours and workplace discrimination as predictors of paternal acceptance two years later (Time 1 paternal acceptance controlled), and tested moderation by youth gender and maternal employment. RESULTS: Multivariate multilevel models revealed a curvilinear association between youth workplace discrimination and father-reported acceptance. Moderation effects of youth gender and mother employment in linear links between youth work experiences and youth-reported acceptance also emerged. Work hours were stronger negative predictors of paternal acceptance for sons than daughters and youth with employed compared to nonemployed mothers. Workplace discrimination was a positive predictor of paternal acceptance of daughters but not sons. CONCLUSIONS: Findings highlight complex patterns in links between youth's work and family relationships, an understudied area. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Perceived underemployment and couple relationships among African American parents: A dyadic approach.

OBJECTIVE: In the United States, underemployment is more common among ethnic minorities, especially African Americans. At the same time, African American couples are at higher risks of marital difficulties than other racial/ethnic groups. This study used a dyadic approach to examine implications of underemployment, as perceived by African American mothers and fathers, for their own and their partners' couple relationship experiences, including relational love and coparenting satisfaction. The vulnerability-stress-adaptation framework of couple relationships guided tests of moderation by depressive symptoms, work hours, workplace discrimination, and expressive personality. METHOD: The sample included 164 African American dual-earner parents (mean age = 40.53 and 43.11 for mothers and fathers) who were interviewed on two occasions across two years. Actor-partner interdependence modeling was used for the analyses. RESULTS: Fathers' underemployment perceptions negatively predicted their own reports of love and coparenting satisfaction. Significant interactions indicated that the negative effects of fathers' perceived underemployment on their own relational love were stronger for fathers with more depressive symptoms, and, for less expressive mothers, on mothers' love and coparenting satisfaction. However, mothers' perceived underemployment was a positive predictor of mothers' love when they worked fewer hours and a negative predictor of mothers' coparenting satisfaction when they had high expressive personality. CONCLUSION: Implications of underemployment experiences for couple relationships differ across gender and need to be considered in the context of partners' vulnerabilities, adaptive characteristics and other stressors. Findings advance understanding of underemployment and work-marriage linkages among African Americans, and highlight the utility of a dyadic approach.

Honey, Do I Look Fat? Perceptions of Spouses' Weight and Weight Concerns Predict Marital Relationship Quality.

The majority of adults in the United States are overweight or obese, and yet Western ideals of beauty mean that low body fat composition is a component of physical attractiveness. In turn, perceived discrepancies between actual and ideal body shape and weight mean that many adults experience weight concerns-- and they also may be dissatisfied with their spouse's weight. This study examined whether weight concerns were linked to romantic relationship quality, an important domain of adult development. Specifically, we applied the Actor-Partner Interdependence Model to test how wives' and husbands' weight concerns and perceptions of their spouses' overweight contributed to their own and their spouse's reports of marital satisfaction and conflict over time. The sample was 197 heterosexual married couples (M age = 40.85 and 42.81 years for wives and husbands, respectively; M length of marriage = 18.6 years at Time 1) with children, who participated in a short-term longitudinal study of family relationships and adolescent development. Two-way interactions between partner perceptions of spouses' weight and gender indicated that husbands' perceptions that their wives were overweight predicted decreases in wives' marital satisfaction and increases in wives' reports of marital conflict across one year. In contrast, wives' perceptions of husbands' weight were not associated with changes in husbands' marital satisfaction or conflict. A two-way interaction between actor and partner weight concerns indicated that individuals reported more marital conflict when there was a discrepancy between their own and their spouse's weight concerns. Finally, a two-way interaction between actor and partner perceptions of spouse's weight indicated that, for individuals whose spouses rated them as below ideal weight, their perceptions of the spouse's overweight predicted their own lower marital satisfaction. Findings suggest that concerns about one's own and one's spouse's weight have negative ramifications for marital relationships.

Interparental conflict and gender moderate the prospective link between parents' perceptions of adolescents' weight and weight concerns.

OBJECTIVE: Parents' comments about their adolescents' weight have been linked with adolescents' disordered eating, but we know little about the personal and contextual conditions that promote or mitigate the effects of parents' perceptions on adolescents' weight concerns. This study examined whether the prospective association between parents' perceptions of adolescents' weight and adolescents' weight concerns differed as a function of exposure to interparental conflict or adolescent gender. METHOD: Participants were 386 adolescents (52% female; ages 11-18 years; predominately Caucasian/European American) from 197 families (i.e., up to two adolescents per family) and their parents. Two-parent families with a firstborn child in 8th, 9th, or 10th grade and a secondborn child 1-4 years younger were recruited to participate in a short-term longitudinal study of adolescent development and family relationships. Annual home interviews were conducted with adolescents and parents. Multilevel models tested whether parents' perceptions of adolescents' weight predicted adolescents' weight concerns one year later and whether interparental conflict and youth gender moderated this prospective association. RESULTS: A significant three-way interaction revealed that when interparental conflict was low, increases in fathers' but not mothers' perceptions of daughters' overweight predicted increases in daughters' weight concerns the following year. In contrast, females exposed to high interparental conflict reported elevated weight concerns the following year regardless of parents' perceptions. Results for males were not significant. DISCUSSION: Findings highlight the role of personal and family context characteristics in the development of weight concerns and the value of addressing family processes within preventive interventions for adolescent females' weight concerns.

Sibling Experiences in Middle Childhood Predict Sibling Differences in College Graduation.

To illuminate how within-family differences in achievement may emerge, this study examined sibling experiences in middle childhood as predictors of sibling differences in college graduation. First- and second-borns from 152 families reported on their experiences with siblings and parents at ages 11.80 (SD = 0.56) and 9.22 (SD = 0.90), respectively, and on their educational attainment at about age 26. Significant childhood predictors of sibling differences in college graduation status included low sibling warmth, fathers' differential time spent with siblings, and perceived unfair differential treatment by parents. Findings suggest long-term implications of early sibling dynamics for educational attainment and provided novel insights into families' role in achievement.

Mexican-Origin Youth's Cultural Orientations and Values: Do Older Sisters and Brothers Matter?

Family is an important context for cultural development, but little is known about the contributions of siblings. This study investigated whether older siblings' cultural orientations and familism values predicted changes in younger siblings' cultural orientations and familism values across 2 years and tested sibling characteristics and younger siblings' modeling as moderators. Participants were 246 Mexican-origin younger (Mage  = 17.72; SD = 0.57) and older siblings (Mage  = 20.65; SD = 1.57) and their parents. Findings revealed that older siblings' Anglo orientations and familism values interacted with younger siblings' modeling: When younger siblings reported high modeling, older siblings' Anglo orientations and values predicted increases in younger siblings' Anglo orientations and values. Discussion highlights the importance of siblings in cultural socialization.

Sibling dynamics in adolescence predict young adult orientations to couple relationships: A dyadic approach.

INTRODUCTION: Adolescents' sibling relationships may serve as a training ground for couple relationships given their similar features, including companionship, closeness and role structure. This study used a dyadic approach to examine sibling intimacy and control in adolescence as predictors of young adults' couple relationship orientations (attachment avoidance and anxiety and attitudes toward marriage). Additionally, research documenting the significance of an other-sex sibling for adolescents' romantic competence guided tests of sibling dyad sex constellation as a moderator of links between sibling relationships and couple relationship orientations in our predominantly heterosexual sample of youth. METHOD: Firstborns and secondborns from 151 families (Time 1 ages M = 16.42, SD = 0.79 and M = 13.83, SD = 1.14, respectively) reported on their sibling relationships in three annual home interviews and on their couple relationship orientations in web surveys ten years after Time 1. RESULTS: Estimating actor-partner interdependence models revealed negative effects of sibling intimacy and positive effects of control toward sibling on avoidant attachment, and positive effects of control toward and by sibling on anxious attachment. Sex constellation moderated the interaction effects of the two siblings' intimacy reports on attitudes toward marriage: Mutual high intimacy among mixed-sex dyads predicted more positive attitudes; among same-sex dyads, adolescents' own intimacy compensated for siblings' lower intimacy in predicting positive attitudes toward marriage. Findings emerged with parent marital love controlled. CONCLUSION: Findings suggest long-term effects of sibling relationships on couple relationship orientations and demonstrate the benefits of using dyadic approaches to examine the implications of sibling relationships.

Gender-Typed Personality Qualities and African American Youth's School Functioning.

Numerous studies document sex differences in African American girls' and boys' academic achievement and motivation, but little is known about how the enactment of gender, such as in the forms of gendered behaviors, attitudes, or personal-social qualities, is related to school functioning. To advance understanding of African American adolescents' academic experiences, this study examined the longitudinal linkages between stereotypically feminine (i.e., expressive) and stereotypically masculine (i.e., instrumental) personality characteristics and school adjustment. The moderating effects of youth's ethnic identity and school racial composition also were tested. Participants were 352 African American youth (50.1% girls; mean age at Time 1 = 12.04 years; SD= 2.03) who participated in annual home interviews. Net of biological sex, expressive traits (kind, sensitive) were positively related to school self-esteem and school bonding for both girls and boys, but youth with higher levels of instrumentality (independent, competitive) exhibited sharper declines in academic achievement across adolescence. School racial composition moderated the effects of instrumentality at the between-person level, such that instrumentality was positively related to school self-esteem only for youth who attended schools with fewer African American students. These results highlight the importance of incorporating gendered personality traits, rather than biological sex alone, into theoretical accounts of African American youth's school functioning.

The Development and Correlates of Gender Role Orientations in African-American Youth.

This study charted the development of gendered personality qualities, activity interests, and attitudes across adolescence (approximately ages 9-18) among 319 African-American youth from 166 families. The relations between daily time spent with father, mother, and male and female peers-the gendered contexts of youth's daily activities-and (changes in) these gender role orientations were also assessed. Boys and girls differed in their gender role orientations in stereotypical ways: interest in masculine and feminine activities, and attitude traditionality generally declined, but instrumentality increased across adolescence and expressivity first increased and later decreased. Some gender differences and variations in change were conditioned by time spent with same- and other-sex gender parents and peers. The most consistent pattern was time with male peers predicting boys' stereotypical characteristics.

Links between gendered leisure time in childhood and adolescence and gendered occupational aspirations.

The world of work remains gender-segregated, and research is needed to identify factors that may give rise to women's and men's vocational choices. This study explored bidirectional relations between youth's gendered career aspirations and the proportions of youth's leisure time spent in stereotypically gendered activities and gendered social contexts. Participants were 203 youth (52% girls) from predominantly white, working and middle class families living in the US, who reported on their occupational aspirations and gendered interests in home interviews and on their daily activities in a series of 7 nightly phone interviews on two occasions, in middle childhood (Mage = 10.9) and in adolescence (Mage = 17.3). Path models revealed that aspirations predicted youth's time use more so than the reverse. Time in gendered social contexts, specifically time in female-only contexts, but not time in gender-typed activities, predicted career aspirations. Implications of these findings and suggestions for future research are discussed.

Longitudinal Course and Correlates of Parents' Differential Treatment of Siblings in Mexican-Origin Families.

Parents' differential treatment (PDT) is a common family dynamic that has been linked to youth development and well-being, including adjustment problems and poor sibling relationships. Much less is known, however, about the developmental course of PDT and the conditions under which parents treat their children differently in adolescence and young adulthood. This study examined longitudinal changes in mothers' and fathers' differential warmth and conflict with their two offspring from early adolescence through young adulthood and examined parents' experiences of individual stress (depressive symptoms and role overload) and marital difficulties as time-varying correlates of (changes in) PDT. We also tested crossover effects to determine whether mothers' experiences of individual stress and marital difficulties were linked to fathers' differential treatment, and vice versa. Participants were mothers, fathers, and two siblings from 246 Mexican-origin families who were interviewed in their homes on three occasions over 8 years. Multilevel models revealed that mothers' and fathers' differential conflict with their two children increased until middle adolescence and then declined into young adulthood, but there were no changes over time for parents' differential warmth. In general, both mothers' and fathers' levels of differential treatment were exacerbated by their own experiences of individual stress and marital difficulties and also by the experiences of their spouses. However, in some cases, greater stress than usual was linked to less differential treatment than usual.

Longitudinal Associations Between Sibling Relational Aggression and Adolescent Adjustment.

Sibling relational aggression is an important but understudied dimension of sibling relationships that has potential implications for adolescents' adjustment. This study examined the longitudinal associations between being the target of sibling relational aggression and adolescent adjustment (i.e., depressive symptoms, risky behavior, self-worth, and romantic competence) among younger and older siblings over a three-year period in adolescence. The moderating roles of birth order, sibling gender, and sibling dyad gender constellation also were tested. Participants were 196 European American adolescent (firstborn-secondborn) sibling pairs who were 16.47 years (SD = 0.80) and 13.88 years (SD = 1.15) of age, respectively, at the onset of this study. Data were collected separately from each sibling during home interviews. Multilevel models revealed that being the target of sibling relational aggression was associated with all four adjustment outcomes at the between-person level, and with risky behavior and romantic competence at the within-person level. However, some of these effects were moderated by sibling dyad characteristics. Although often overlooked in the literature on adolescence, sibling relationship dynamics play a key role in youth development and adjustment.

Parents' Social Comparisons of Siblings and Youth Problem Behavior: A Moderated Mediation Model.

Parents compare their children to one another; those comparisons may have implications for the way mothers and fathers treat their children, as well as their children's behavior. Data were collected annually for three years with parents, firstborns, and secondborns from 385 families (Time 1 age: firstborns, 15.71, SD = 1.07, 52% female; secondborns, 13.18, SD = 1.29, 50% female). Parents' beliefs that one child was better behaved predicted differences in siblings' reports of parent-child conflict. Additionally, for siblings close in age, mothers' comparisons at Time 1 predicted youth's problem behavior at Time 3 through siblings' differential conflict with mothers. The results support and extend tenets from Social Comparison and Expectancy Value theories in regards to social comparison within families.

Daily antecedents and consequences of nightly sleep.

Sleep can serve as both cause and consequence of individuals' everyday experiences. We built upon prior studies of the correlates of sleep, which have relied primarily on cross-sectional data, to examine the antecedents and consequences of sleep using a daily diary design. Specifically, we assessed the temporal sequence between nightly sleep and daily psychosocial stressors. Parents employed in a US information technology company (n = 102) completed eight consecutive daily diaries at both baseline and 1 year later. In telephone interviews each evening, participants reported on the previous night's sleep hours, sleep quality and sleep latency. They also reported daily work-to-family conflict and time inadequacy (i.e. perceptions of not having enough time) for their child and for themselves to engage in exercise. Multi-level models testing lagged and non-lagged effects simultaneously revealed that sleep hours and sleep quality were associated with next-day consequences of work-to-family conflict and time inadequacy, whereas psychosocial stressors as antecedents did not predict sleep hours or quality that night. For sleep latency, the opposite temporal order emerged: on days with more work-to-family conflict or time inadequacy for child and self than usual, participants reported longer sleep latencies than usual. An exception to this otherwise consistent pattern was that time inadequacy for child also preceded shorter sleep hours and poorer sleep quality that night. The results highlight the utility of a daily diary design for capturing the temporal sequences linking sleep and psychosocial stressors.
