Mother-Child Closeness and Adult Children's Time and Financial Assistance.

OBJECTIVES: Drawing on the intergenerational solidarity framework and life course perspective, the authors assessed how mother-child closeness across different life stages is associated with adult children's time and financial assistance to mothers in later life. METHODS: Using children's reports of their perceived closeness to mothers from Waves 1 to 4 of the National Longitudinal Study of Adolescent to Adult Health (Add Health) and mothers' reports about adult children's time and financial assistance from Wave 2 of the Add Health Parent Study (AHPS) in the United States, the authors investigated how mother-child closeness during adolescence, emerging adulthood, and young adulthood is related to midlife adult children's support with a focus on difference between mother-daughter (N = 934) and mother-son (N = 899) dyads. RESULTS: Closeness during young adulthood was an important determinant of adult children's time assistance to their mothers, regardless of child's gender. Daughters' closeness with mothers during young adulthood also had a direct association with their financial support to mothers but not sons'. In contrast, sons' perceived closeness during emerging adulthood had a direct association with their financial support later in life. Closeness during adolescence had no direct association with later-life transfers of time or money but had an indirect association through its influence on mother-child relationships at subsequent life stages. DISCUSSION: Mother-child closeness is a continuously evolving process. Although mother-child bond formed during adolescence has no direct influence on help to mothers later in life, it shapes the progression of mother-child interactions over time that eventuates in support.

Exploring the Interaction Between Preschool Executive Control and Caregiver Emotion Socialization in Predicting Adolescent Weight Trajectories.

There is a critical need for research examining how neural vulnerabilities associated with obesity, including lower executive control, interact with family factors to impact weight trajectories across adolescence. Utilizing a longitudinal design, the present study investigated caregivers' emotion socialization practices as a moderator of the association between preschool executive control and adolescent body mass index (BMI) trajectories. Participants were 229 youth (Mage = 5.24, SD = 0.03; 47.2% assigned female at birth; 73.8% White, 3.9% Black, 0.4% Asian American, 21.8% multiracial; 12.7% Hispanic) enrolled in a longitudinal study. At preschool-age, participants completed performance-based executive control tasks, and their caregivers reported on their typical emotion-related socialization behaviors (i.e., supportive and nonsupportive responses to children's negative emotions). Participants returned for annual laboratory visits at ages 14 through 17, during which their height and weight were measured to calculate BMI. Although neither preschool executive control nor caregiver emotion-related socialization behaviors were directly associated with BMI growth in adolescence, supportive responses moderated the association between executive control and BMI trajectories. The expected negative association between lower preschool executive control and greater BMI growth was present at below average levels of supportive responses, suggesting that external regulation afforded by supportive responses might reduce risk for adolescent overweight and obesity among children with lower internal self-regulatory resources during preschool. Findings highlight the importance of efforts to bolster executive control early in development and targeted interventions to promote effective caregiver emotion socialization (i.e., more supportive responses) for youth with lower internal self-regulatory abilities to mitigate risk for overweight and obesity and promote health across childhood and adolescence.

Maternal Distress and Adolescent Mental Health in Poor Chinese Single-Mother Families: Filial Responsibilities-Risks or Buffers?

Single motherhood and poverty have a significant, negative impact on mothers and their children. When their mothers experience maternal distress, adolescent children have to take up more instrumental and emotional filial responsibilities to comfort their mother and adapt to related changes. Based on 325 mother-child dyads of Chinese single-mother families experiencing economic disadvantage, this study examined the relationship between maternal distress and adolescent mental health problems (indexed by anxiety and depression) and the moderating roles of instrumental and emotional filial responsibilities. Results indicated that maternal distress was positively associated with anxiety and depression in adolescent children. In addition, instrumental filial responsibility intensified the associations of maternal distress with adolescent anxiety and depression. Moreover, the moderating role of emotional filial responsibility in the predictive relationship between maternal distress and adolescent anxiety was different in boys and girls. Adolescent girls with more emotional filial responsibility reported higher adolescent anxiety than did those who shouldered less emotional filial responsibility when their mother exhibited more distress, whereas the relationship between maternal distress and adolescent anxiety was stable in boys, regardless of emotional filial responsibility. In short, the present study showed that parentification was likely to occur in poor Chinese single-mother families, and adolescent children who took up a more caregiving role in the family exhibited poorer mental health. Family counselling and tangible support for single-mother families experiencing economic disadvantage are urged.

Patterns of Observed Dyadic Ethnic-Racial Socialization among Black and Latinx Families in Response to a Hypothetical Experience of Discrimination at School.

Ethnic-racial socialization has primarily been examined as a unidirectional, caregiver-directed process. Instead, applying the Theory of Racial Socialization in Action (Smith-Bynum, 2023), the current study observed caregiver-youth conversations about a hypothetical discriminatory experience at school for patterns of dyadic ethnic-racial socialization. Participants were 353 Black (39.7%), Latinx (47.3%), and multiracial/ethnic (13%) pre-adolescents (Mage = 11.19, SD = 0.43; 45.3% female) and their caregivers (94% mothers) with low income from Dallas, Texas. Five subgroups of dyads were identified (High Dyadic Engagement, Parent-Led, Justice Salient Advocates, Child-Dominant and Low Dyadic Engagement) that differed by demographic characteristics of the dyads (e.g., race/ethnicity, caregiver education). Observing ethnic-racial socialization in action with dyads could improve the delivery of interventions to better meet the needs of families.

Caregivers' Sense of Coherence and Untreated Dental Caries in Children and Adolescents: A Cross-Sectional Study

ABSTRACT Objective: To associate caregivers' sense of coherence (SOC) and untreated caries with oral health status in children covered by a dental public health system. Material and Methods: A convenience sample of caregivers/children in Angra dos Reis, Brazil, was surveyed. Caregivers' SOC was evaluated using the 13-question version questionnaire. For both caregivers/children, sociodemographic information was acquired and caries experience was evaluated by DMFT/dmft and PUFA/pufa index. Statistical associations between children's untreated carious teeth and interest variables from the caregivers were evaluated by binary logistic regression assessed by generalized linear modeling. Results: A total of 233 pairs of caregivers-children were included. Children's untreated permanent and primary carious teeth represented 34.8% and 62.2% of the caries experience, respectively and at least one PUFA/pufa scored tooth was detected in 22.7% of them. Caregivers' DMFT was 13.5±7.0, while 33.6% scored on PUFA. A total of 62.1% of them presented untreated carious lesions. Results from the univariate model, correlating children's untreated caries and caregivers' attributes showed a statistical significance for SOC values (p<0.015), untreated decayed teeth (p<0.035), self-perception of oral health (p<0.022) and oral impact on daily performance (p<0.010). The multivariate logistic first model kept the statistical significance only for the caregiver's untreated decayed teeth. Conclusion: Caregivers' SOC and untreated carious teeth could be used as indicators of dental treatment needs in their offspring.

What factors influence dyadic synchrony? A systematic review of the literature on predictors of mother-infant dyadic processes of shared behavior and affect.

Dyadic behavioral synchrony is a complex interactional process that takes place between the mother and her infant. In the first year of life, when the infant is prelinguistic, processes such as synchrony enable the dyad to communicate through shared behavior and affect. To date, no systematic review has been carried out to understand the risk and protective factors that influence behavioral synchrony in the mother-infant dyad. The aim of this review was to identify and evaluate the factors that influence behavioral synchrony in the mother-infant dyad, when the infant is between 3 and 9 months old. Key electronic databases were searched between 1970 and April 2021, and 28 eligible studies were identified for review. As the results were largely heterogeneous, four subgroups of factors were identified: (i) infant demographics, (ii) physiological factors, (iii) maternal mental health, and (iv) miscellaneous factors. Identified risk factors and covariates suggest that social determinants of health, underpinned by biological factors, play a large role in influencing behavioral synchrony within the dyad. Implications for the need to identify additional risk and protective factors, as well as design support for at-risk families are discussed.

La sincronía diádica del comportamiento es un proceso complejo de interacción que se lleva a cabo entre la madre y su infante, y en el primero año de vida, cuando el infante está en la época prelingüística. Los procesos como la sincronía le permiten a la díada comunicarse a través del comportamiento y el afecto compartido. Hasta la fecha, ninguna revisión sistemática se ha llevado a cabo para comprender los factores de riesgo y de protección que influyen la sincronía del comportamiento en la díada madre-infante. El propósito de esta revisión fue identificar y evaluar los factores que influyen la sincronía del comportamiento en la díada madre-infante, cuando el infante tiene entre 3 y 9 meses de nacido. Se investigaron bancos claves de datos electrónicos entre 1970 y abril de 2021, y se identificaron 28 estudios aptos para la revisión. Como los resultados fueron en gran parte heterogéneos, se identificaron cuatro subgrupos de factores: (i) datos demográficos del infante, (ii) factores fisiológicos, (iii) salud mental materna, y (iv) factores misceláneos. Los factores de riesgo y covariantes identificados señalan que los determinantes sociales de salud, sustentados por factores biológicos, juegan un papel grande en cuanto a influir la sincronía del comportamiento dentro de la díada. Se discuten las implicaciones para la necesidad de identificar factores de riesgo y de protección adicionales, así como también diseñar el apoyo para familias bajo riesgo.

La synchronie comportementale dyadique est un processus interactionnel complexe qui prend place entre la mère et son bébé. Dans la première année de la vie, quand le bébé ne parle pas, les processus tels que la synchronie permettent à la dyade de communiquer à travers un comportement et un affect partagés. Jusqu'à présent aucune revue systématique n'a été faite pour comprendre les facteurs de risque et les facteurs de protection qui influencent la synchronie comportementale chez la dyade mère-bébé. Le but de cette revue était d'identifier et d'évaluer les facteurs qui influencent la synchronie comportementale chez la dyade mère-bébé, quand le bébé avait entre 3-9 mois. Les bases de données électroniques clés ont fait l'objet des recherches entre 1970 et avril 2021, et 28 études admissibles ont été identifiée pour la revue. Puisque les résultats étaient largement hétérogènes, quatre sous-groupes de facteurs ont été identifiés: (1) données démographiques du bébé, (ii) facteurs physiologiques, (iii) santé mentale maternelle, et (iv) facteurs divers. Les facteurs de risque identifiés et les co-variables suggèrent que les déterminants sociaux de la santé, sous-tendus par des facteurs biologiques, jouent un rôle important en influençant la synchronie comportementale au sein de la dyade. Les implications quant au besoin d'identifier des facteurs de risque et de protection supplémentaire, ainsi que des soutiens aux familles à risque sont discutées.

Infant behavioural effects of smartphone interrupted parent-infant interaction.

Infants are vulnerable to changes in the dyadic synchrony with their caregivers, as demonstrated in numerous experiments employing the still-face paradigm. The sudden lack of attunement causes infant stress reactions and the still-face literature have suggested potential long-term costs of this in terms of development of social, emotional and cognitive skills. Acknowledging the rapid technological development accompanied by altered practices in the parent-infant interaction, the current study investigates infant behavioural reactions in a similar experimental paradigm, manipulating parental responsiveness and sensitivity in a slightly different manner. In the current study, the parent interrupts the ongoing interaction, simulating occupation with a smartphone, rather than making a 'still-face'. In a cross-sectional design, infants of six, nine and twelve months display increased levels of protest behaviour in response to the interrupted interaction with their parent, together with lowered levels of positive engagement and social monitoring, suggesting similar behavioural responses as the still-face effect. Implications for infant social and emotional development, as well as for mindful tech habits are discussed.

Associations among stress and language and socioemotional development in a low-income sample.

Stress has been linked with children's socioemotional problems and lower language scores, particularly among children raised in socioeconomically disadvantaged circumstances. Much of the work examining the relations among stress, language, and socioemotional functioning have relied on assessments of a single dimension of maternal stress. However, stress can stem from different sources, and people may appraise stressors differently. Taking a dimensional approach, this manuscript characterizes stress in multiple ways: as an overall composite; across the constructs of psychological appraisal vs. environmental stressors; and the independent contributions of a variety assessments. Data are from 548 mother-infant dyads (M = 13.14 months, SD = 2.11) who served as the control group for a poverty reduction clinical trial. Mothers completed questionnaires regarding the different types of stresses they may have experienced, as well as their children's language and socioemotional development. Results indicate that, collectively, higher maternal report of stress is associated with lower reports of children's socioemotional and language development. In addition, maternal psychological appraisals of stress were associated with both socioemotional and language development, whereas reports of environmental stressors were only associated with socioemotional development. Together, these findings suggest that maternal reports of stress are associated with lower maternal report of child development among low-income children.

The Dutch Infant Caregiving Assessment Scales: Psychometric properties in mothers with and without a severe psychiatric disorder.

OBJECTIVES: This study examines the psychometric properties of the Dutch adaptation of the Infant Caregiving Assessment Scales (INCAS). This standardized observation procedure is the first to assess both emotional and instrumental caregiving skills of mothers with a severe psychiatric disorder, during the postpartum period. METHODS: Mothers with and without a severe psychiatric disorder (N = 123) were observed at home at the infant age of 6 weeks during daily caregiving; changing a diaper, bathing, dressing, and feeding. Recordings of observations were coded independently by trained coders, blind for group membership. Subsequently, the component structure, internal consistency, interrater reliability, and concurrent validity of the INCAS were examined. RESULTS: Principal component analysis largely confirmed the two a priori defined caregiving domains. The internal consistencies of the emotional and instrumental domains were deemed excellent and good, respectively. The interrater reliability was substantial for the emotional domain and moderate for the instrumental domain. Furthermore, evidence for good concurrent validity of the emotional domain was found. Lastly, significant correlations were found between specific instrumental caregiving skills and maternal neuropsychological functioning. CONCLUSION: Psychometric findings support the INCAS as a comprehensive and reliable instrument for standardized assessment of caregiving by mothers with a severe psychiatric disorder.

Coverage and factors associated with mother and newborn skin-to-skin contact in Nigeria: a multilevel analysis.

BACKGROUND: Mother and newborn skin-to-skin contact (SSC) is an immediate postpartum intervention known to improve the health of newborn and mothers alike. Albeit, there is paucity of data that explored the coverage or factors associated with SSC in Nigeria. Therefore, we aimed to explore the coverage and hierarchical nature of the factors associated with SSC among women of reproductive age in Nigeria. METHODS: The 2018 Nigeria Demographic and Health Survey (NDHS) data was used for this study. Data on 29,992 women who had ever given birth were extracted for analysis. SSC was the outcome variable as determined by women's report. A multivariable multilevel logistic regression model was used to estimate the fixed and random effects of the factors associated with SSC. Statistical significance was determined at p< 0.05. RESULTS: The coverage of SSC was approximately 12.0%. Educated women had higher odds of SSC, when compared with women with no formal education. Those who delivered through caesarean section (CS) had 88% reduction in SSC, when compared with women who had vaginal delivery (OR= 0.12; 95%CI: 0.07, 0.22). Women who delivered at health facility were 15.58 times as likely to practice SSC, when compared with those who delivered at home (OR= 15.58; 95%CI: 10.64, 22.82). Adequate ANC visits and low birth weight significantly increased the odds of SSC. Women from richest household were 1.70 times as likely to practice SSC, when compared with women from poorest household (OR= 1.70; 95%CI: 1.04, 2.79). There was 65% reduction in SSC among women with high rate of community non-use of media, when compared with women from low rate of community non-use of media (OR= 0.35; 95%CI: 0.20, 0.61). CONCLUSION: SSC coverage was low in Nigeria. Moreover, individual, household and community level factors were associated with SSC. More enlightenment should be created among women to bring to limelight the importance of SSC specifically to newborn's health.

Bedsharing in Early Childhood: Frequency, Partner Characteristics, and Relations to Sleep.

Bedsharing (sharing a bed with others during sleep) in early childhood (3-5 years old) is common across Western and non-Western societies alike. Though prior work indicates that bedsharing may relate to impairments in child sleep quantity or quality, the majority of studies conducted in young children are limited to parent-child bedsharing and rely almost exclusively on caregiver reports to measure child sleep. Here, the authors endeavored to gain further insights into the diversity of bedsharing practices among children in the United States, including how different bedsharing partners (caregivers, siblings) might impact actigraphy-derived measures of children's sleep. Using a sample of 631 children ages 2:9 to 5:11 years, we found that over 36% of children bedshared in some form overnight, with approximately 22% bedsharing habitually. In a subset of children for whom actigraphy measures were collected (n = 337), children who bedshared habitually (n = 80) had significantly shorter overnight sleep, later sleep and wake times, and longer naps than solitary sleepers (n = 257), even when controlling for socioeconomic status. Despite supplementing their shorter overnight sleep with longer naps, habitually bedsharing children had significantly shorter 24-hr sleep time than did solitary sleepers, though differences in sleep efficiency were nonsignificant for all sleep periods. Additionally, sleep efficiency, onset latency, and duration did not differ between children who habitually bedshared with siblings versus those who habitually bedshared with parents. The present results add to prior work examining family contextual correlates of sleep differences in early childhood and provide a more objective account of relations between bedsharing and child sleep.

Adolescents' perceptions of maternal response to negative affect predict emotional reactivity during mother-daughter interaction: A multi-modal assessment.

Parental socialization of emotion consists of parental behaviors that scaffold child emotional reactivity and regulation. The current study examined whether adolescents' perceptions of their mothers' supportive versus non-supportive responses to negative emotions could predict adolescent emotional reactivity. Thirty adolescent girls (Mage  = 14.41 [1.55]) reported on how their mothers typically respond to their negative emotions and then completed a laboratory-based mother-adolescent interaction task. A multi-modal assessment of adolescent emotional reactivity during the interaction included adolescents' skin conductance levels (SCLs) and state anxiety, and mother-daughter interactions were behaviorally coded to assess how often dyads engaged in both negative and positive escalation (i.e., a pattern of negative or positive behavior of one partner being reciprocated by the other). Adolescents who reported that their mothers used more non-supportive responses to their negative emotion tended to exhibit higher SCL and engage in more negative escalation with their mothers during the interaction task. Furthermore, adolescents' SCL was positively correlated with both their state anxiety levels and negative escalation during the task. Together, these findings suggest that adolescents who perceive their mothers as less supportive of negative emotions are more likely to exhibit greater negative emotionality during parent-adolescent interaction, which may relate to risk for emotional disorders.

Maternal Differential Treatment and Psychological Well-Being: The Mediating Role of Marital Tension and Sibling Tension?

OBJECTIVES: Past research used equity theory and social comparison theory to explain the direct effect of maternal differential treatment (MDT) on psychological well-being. However, this focus on psychological pathways ignores possible social pathways, such as indirect effects of MDT on well-being through disrupting other family relationships. This study uses stress proliferation theory to argue that MDT, as a primary stressor in mother-child relationships, can produce secondary stressors in other family relationships (e.g., sibling tension and marital tension), which in turn leads to lower psychological well-being. METHODS: To investigate this mechanism, we conducted multilevel mediation analysis using data collected from 720 adult children nested within 308 families, as part of the Within-Family Differences Study. RESULTS: We found that sibling tension mediates the association between adult children's perceptions of maternal disfavoritism and their psychological well-being-a process we call the stress proliferation of maternal disfavoritism. In contrast, adult children's perceptions of maternal favoritism cannot trigger this stress proliferation process of producing marital tension nor sibling tension. DISCUSSION: The evaluation of the stress proliferation process of maternal favoritism and disfavoritism can help us to understand the difference in effects across various dimensions of MDT. This study contributes to the literature on social relationships as social determinants of health by investigating how intergenerational relationships are connected to other family relationships to affect family members' health.

Family SES and maternal sensitivity predict infant patterns of regulatory behavior in Brazilian dyads.

Infant's patterns of regulatory behavior contribute to infant socioemotional development and attachment. These behavioral patterns affect and are affected by the quality of mother-infant interaction. In most studies with full-term infants, the Social-Positive Oriented pattern (i.e., the infant's ability to soothe his/her emotions in the context of reciprocal and positive interactions) is the most prevalent pattern, followed by the Distressed-Inconsolable and by the Self-Comfort Oriented patterns. However, these patterns are understudied in other populations beyond the US and European countries. The current research addresses this gap by studying the regulatory behavior patterns and their association with mother-infant interactions in Brazilian dyads and evaluating the association of these regulatory patterns with demographics. Analyses were based on data collected for 40 infants (20 boys, 20 girls) and their mothers. Infants' regulatory behavior patterns were evaluated in the Face-to-Face Still-Face paradigm and mother-infant interaction was evaluated during free play at 3 months age. Notably, our findings indicate that Distressed-Inconsolable was the most prevalent pattern in this sample; followed by the Social-Positive Oriented and the Self-Comfort Oriented patterns. Furthermore, we found that maternal sensitivity and family SES (social-economic status) predicted infant patterns of regulatory behavior.

Assessment of the nutritional status of children according to maternal reports: Are mothers' perceptions of their children's appetite accurate?

INTRODUCTION: This study determined whether there is a difference in the nutritional status of children with good and poor appetites, as reported by their mothers. METHODS: In all, 70 volunteer mothers of children aged 6-60 months participated in the study. Information about the nutrition of the child was obtained from the mothers via a questionnaire. RESULTS: Based on the mothers' statements, no significant difference was found in the mean or median values of the anthropometric measurements between children with good and poor appetites (p>.05), and no significant difference was observed between daily consumed energy and macro- and micronutrients (p>.05). While the blood zinc levels of children with a good appetite were higher than those with a poor appetite (p<.05), there was no difference regarding other parameters (p>.05). CONCLUSION: In this study, no significant difference was evident between children defined as having good or poor appetite by their mothers, especially in terms of energy and nutrients.

Hair sampling for cortisol analysis with mother-toddler dyads living in low-income homes.

BACKGROUND: A first step to advance stress science research in young children is understanding the relationship between chronic stress in a mother and chronic stress in her child. One non-invasive measure of chronic stress is hair cortisol. However, little is known about strategies for hair sampling in mother-toddler dyads living in low-income homes in the U.S. To address prior limitations, the purpose of this study was to understand the feasibility of sampling hair for cortisol analysis in mother-toddler dyads living in low-income homes in the U.S. We examined feasibility related to participation, eligibility, and gathering an adequate hair sample weight. METHODS: We approached 142 low-income, racially diverse, urban-dwelling mothers who were participating in an ongoing longitudinal birth cohort study for informed consent to cut approximately 150 hairs from the posterior vertex of their scalp and their toddlers' (20-24 months) scalp. We demonstrated the process of sampling hair with a hairstyling doll during home visits to the mother and toddler using rounded-end thinning shears. RESULTS: Overall, 94 of 142 mother-toddler dyads (66 %) participated in hair sampling. The most common reason for participation refusal was related to hairstyle. All but three hair samples were of adequate weight for cortisol extraction. DISCUSSION: The findings from this study can help researchers address sampling feasibility concerns in hair for cortisol analysis research in mother-toddler dyads living in low-income homes in the U.S.

Adaptive Parenting Among Low-Income Black Mothers and Toddlers' Regulation of Distress.

Parenting differs in purpose and strategy according to cultural background (Brooks-Gunn & Markman, 2005; Iruka, LaForett, & Odom, 2012). The current study tests a unique latent factor score, Adaptive Parenting, that represents culturally-relevant, positive parenting behaviors: maternal coping with stress through reframing, maternal scaffolding of toddlers' learning during a low-stress task, and maternal commands during a high-stress task. Participants were Black mothers (N = 119; Mage  = 27.78) and their 24- to 30-month-old toddlers. Families were part of a broader study examining family resilience among urban, low-income young children and their families. Results demonstrate that the proposed variables align on a single factor and positively predict toddlers' emotion regulation. Findings are discussed in the context of Black culturally-specific parenting processes.

Prenatal Predictors of Maternal-infant Attachment.

BACKGROUND.: Increasingly, occupational therapists are working with women in the perinatal period, including supporting the developing mother-child relationship. PURPOSE.: To examine prenatal predictors of maternal-infant attachment (maternal-fetal attachment, sensory patterns, adult attachment, perinatal loss, and mental health) that may provide possible avenues for assessment and intervention by occupational therapists. METHOD.: Women (N = 60) were assessed during pregnancy and within one year postpartum in a cohort study. Independent t-tests, correlations, and multivariate regression models were conducted. FINDINGS.: Low threshold maternal sensory patterns, more insecure adult attachment, and poorer quality of maternal-fetal attachment were each correlated with less optimal maternal-infant attachment. Quality of prenatal attachment was the best predictor of overall postnatal attachment in multivariate regression models. IMPLICATIONS.: Occupational therapists working in a range of clinical settings (e.g., mental health, substance use, and perinatal care) may work with women during pregnancy to promote their relationship with their developing baby in utero and after birth.

Mother-child dyadic influences of affect on everyday movement behaviors: evidence from an ecological momentary assessment study.

BACKGROUND: Research has shown that affect is associated with everyday movement behaviors in children and adults. However, limited work to date has investigated dyadic influences of momentary affect on moderate-to-vigorous physical activity (MVPA) and sedentary time among children and their mothers using ecological momentary assessment (EMA). METHODS: Mothers and their children (eight to 12-years-old at baseline) from the Los Angeles metropolitan area participated in a longitudinal study with six semi-annual measurement waves across three years. During each measurement wave, mothers and children reported momentary negative and positive affect via a custom smartphone-based EMA application across seven days (randomly sampled up to eight times per day). Each dyad member's momentary affective states were used to predict their own and the other dyad member's accelerometer-measured MVPA and sedentary time in the prompt-matched 45-min time window. Multilevel modeling within the actor-partner interdependence model (APIM) framework was applied to accommodate the nested dyadic nature of the data. RESULTS: At the within-subject level, when children had higher-than-usual positive affect, they engaged in greater MVPA and less sedentary time in the prompt-matched 45-min window (actor effects; ps < .001). When mothers experienced higher-than-usual positive affect, they engaged in more sedentary time in the same 45-min window (actor effect; p < .001). Children's higher-than-usual positive affect also predicted more MVPA time of their mothers (partner effect; p < .05). At the between-subjects level, for mothers who reported higher average negative affect than other mothers, their children overall had less MVPA and more sedentary time (partner effects ps < .05). CONCLUSIONS: This study extends the literature by demonstrating that mothers' and children's everyday physical activity and sedentary time are not only associated with their own affective states, but also may be influenced by the affective states of each other. Our findings suggest that affective states have the potential to influence movement behaviors in mother-child dyads' everyday lives. Affective underpinnings of physical activity and sedentary behaviors should be further studied in order to develop family-based intervention strategies to influence these behaviors.

Investigating the momentary association between maternal support and children's fruit and vegetable consumption using ecological momentary assessment.

Despite compelling evidence that fruit and vegetable (F/V) consumption can reduce the risk of obesity and chronic disease, most children fail to meet the daily recommendations for dietary consumption. Theoretical models and empirical findings suggest that parents play a key role in guiding children's overall dietary behaviors. To extend previous findings, the current study utilized ecological momentary assessment (EMA) on smartphones to assess the within-subject and between-subject effects of maternal support (i.e., encouragement, preparation) of F/V on their child's F/V consumption. Mother-child dyads (n = 191) completed six semi-annual 7-day waves of EMA surveys. EMA assessed mothers' past 2-h support for F/V and children's F/V consumption. At the within-subject level, greater maternal encouragement for F/Vs (OR = 2.41) and maternal preparation of F/Vs (OR = 1.43) than usual were associated with increased odds of their child eating F/V during the same 2-h window. At the between-subject level, greater maternal preparation of F/V (OR = 5.99), compared to other mothers, was associated with increased odds of their child eating F/V. Children with lower BMI (vs. higher BMI) were more likely to consume F/Vs when their mothers encouraged them to eat F/V (OR = 0.74). These findings suggest that maternal support may have a strong and immediate effect on children's F/V consumption. Theoretical models on behavior change should consider how explanatory factors, such as parental support, may vary at the momentary level. Boosting maternal support at the momentary level may be a critical component of future mobile-based interventions to address childhood obesity.
