RESUMO

Importance: Lower educational attainment is associated with increased risk of adverse pregnancy outcomes, but it is unclear which pathways mediate this association. Objective: To investigate the association between educational attainment and pregnancy outcomes and the proportion of this association that is mediated through modifiable cardiometabolic risk factors. Design, Setting, and Participants: In this 2-sample mendelian randomization (MR) cohort study, uncorrelated (R2 < 0.01) single-nucleotide variants (formerly single-nucleotide polymorphisms) associated with the exposure (P < 5 × 10-8) and mediators and genetic associations with the pregnancy outcomes from genome-wide association studies were extracted. All participants were of European ancestry and were largely from Finland, Iceland, the United Kingdom, or the US. The inverse variance-weighted method was used in the main analysis, and the weighted median, weighted mode, and MR Egger regression were used in sensitivity analyses. In mediation analyses, the direct effect of educational attainment estimated in multivariable MR was compared with the total effect estimated in the main univariable MR analysis. Data were extracted between December 1, 2022, and April 30, 2023. Exposure: Genetically estimated educational attainment. The mediators considered were genetically estimated type 2 diabetes, body mass index, smoking, high-density lipoprotein cholesterol level, and systolic blood pressure. Main Outcomes and Measures: Ectopic pregnancy, hyperemesis gravidarum, gestational diabetes, preeclampsia, preterm birth, and offspring birth weight. Results: The analyses included 3 037 499 individuals with data on educational attainment, and those included in studies on pregnancy outcomes ranged from 141 014 for ectopic pregnancy to 270 002 with data on offspring birth weight. Each SD increase in genetically estimated educational attainment (ie, 3.4 years) was associated with an increased birth weight of 42 (95% CI, 28-56) g and an odds ratio ranging from 0.53 (95% CI, 0.46-0.60) for ectopic pregnancy to 0.81 (95% CI, 0.71-0.93) for preeclampsia. The combined proportion of the association that was mediated by the 5 cardiometabolic risk factors ranged from -17% (95% CI, -46% to 26%) for hyperemesis gravidarum to 78% (95% CI, 10%-208%) for preeclampsia. Sensitivity analyses accounting for pleiotropy were consistent with the main analyses. Conclusions and Relevance: In this MR cohort study, intervening for type 2 diabetes, body mass index, smoking, high-density lipoprotein cholesterol level, and systolic blood pressure may lead to reductions in several adverse pregnancy outcomes associated with lower levels of education. Such public health interventions would serve to reduce health disparities attributable to social inequalities.

RESUMO

Based on the integration of ecological systems theory and the risk and protective factor model, the current study tested whether individual relative deprivation mediated the association between perceived social support and adolescents' experiential avoidance and whether this mediation model was moderated by subjective social class. A sample of 582 senior high school students in China participated in the current survey. The results indicated that perceived social support was negatively related to the students' experiential avoidance. Mediation analysis showed a significant indirect effect of perceived social support on experiential avoidance, via individual relative deprivation. Moreover, the mediation effect of individual relative deprivation was moderated by subjective social class. Specifically, the negative relationship between perceived social support and individual relative deprivation, and the direct relationship between perceived social support and experiential avoidance were stronger for adolescents with low subjective social class. In contrast, the positive relationship between individual relative deprivation and experiential avoidance was stronger for adolescents with high subjective social class.

RESUMO

BACKGROUND: The inverse association between education and obesity was previously found in numerous studies. This study aims to assess several possible mediators in the educational disparities in adiposity. We hypothesize the potential mediating role of lifestyle, socioeconomic, and mental health factors in the association between education and adiposity. METHODS: Cross-sectional population-based sample from Czechia included 2,154 25-64 years old subjects (54.6% women). Education was classified as high, middle, and low. Adiposity was assessed as a latent variable based on body fat percentage, BMI, waist circumference, and visceral fat. The mediation potential of unhealthy dietary behavior, alcohol intake, smoking, sedentary behaviors, income, stress, depression, and quality of life was assessed in age-adjusted sex-specific multiple mediation models. RESULTS: The negative direct effect of education on adiposity was statistically significant at 5% level of significance in both sexes. For men, the indirect effect was statistically significant via sedentary behavior (ß = 0.041; 95% CI [0.025-0.062]) with a mediation ratio of 23.7%. In women, the indirect effect was statistically significant via dietary risk (ß = -0.023, 95% CI [-0.037, -0.013]), alcohol intake (ß = -0.006; 95% CI [-0.014, -0.001]), sedentary behavior (ß = 0.012, 95% CI [0.004,0.023]), income (ß = -0.022; 95% CI [-0.041, -0.004]), and mental health (ß = -0.007; 95% CI [-0.019, -0.001]). The total mediation ratio in women was 30.5%. CONCLUSIONS: Sedentary behaviors had mediating role in the association between education and adiposity in both sexes, with more important role in men. In addition, unhealthy diet and lower income partially mediated the educational gradient in adiposity in women.

RESUMO

BACKGROUND: Preterm birth affects between 7% and 8% of births in the UK and is a leading cause of infant mortality and childhood disability. Prevalence of preterm birth has been shown to have significant and consistent socioeconomic inequalities. OBJECTIVE: To estimate how much of the association between socioeconomic status (SES) and gestational age at birth is mediated by maternal smoking status and maternal body mass index (BMI). METHODS: Retrospective cohort study of a maternity hospital in the UK. The analysis included all singleton live births between April 2009 and March 2020 to mothers 18 years old and over, between 22 weeks and 43 weeks gestation. We estimate two measures of mediation for four low gestational age categories: (i) The proportion eliminated the percentage of the effect of SES on low gestational age at birth that would be eliminated by removing the mediators, through the Controlled Direct Effects estimated using serial log-binomial regressions; and (ii) The proportion mediated is the percentage of the effect removed by equalising the distribution of the mediators across socioeconomic groups, estimated using Interventional Disparity Measures calculated through Monte Carlo simulations. RESULTS: Overall, 81,219 births were included, with 63.7% low SES. The risk of extremely (0.3% of all births), very (0.7%) and moderately preterm birth (6.3%) was 1.71 (95% Confidence Interval [CI] 1.29, 2.31), 1.43 (95% CI 1.18, 1.73) and 1.26 (95% CI 1.19, 1.34) times higher in the low SES, compared to higher SES respectively. The proportion of this inequality eliminated by removing both maternal smoking and BMI was 43.4% for moderately preterm births. The proportion mediated for smoking was 33.9%, 43.0% and 48.4% respectively. CONCLUSIONS: Smoking during pregnancy is a key mediator of inequalities in preterm birth, representing an area for local action to reduce social inequalities in preterm birth.

RESUMO

OBJECTIVES: Deprived living environments contribute to greater heart failure (HF) risk among non-Hispanic Black persons, who disproportionately occupy disadvantaged neighborhoods. The mechanisms for these effects are not fully explicated, partially attributable to an insufficient understanding of the individual factors that contribute additional risk or resilience to the impact of neighborhood disadvantage on health. The objective of this study was, therefore, to clarify the complex pathways over which such exposures act to facilitate more targeted, effective interventions. Given the evidence for a mediating role of biological age and a moderating role of individual psychosocial characteristics in the neighborhood disadvantage-HF link, we tested a moderated mediation mechanism. METHODS: Using multilevel causal moderated mediation models, we prospectively examined whether the association of neighborhood disadvantage with incident HF mediated through accelerated biological aging, captured by the GrimAge epigenetic clock, is moderated by hypothesized psychosocial risk (negative affect) and resilience (optimism) factors. RESULTS: Among a sample of 1,448 Black participants in the shared Jackson Heart Study-Atherosclerosis Risk in Communities cohort (mean age 64.3 years), 334 adjudicated incident hospitalized HF events occurred over a median follow-up of 18 years. In models adjusted for age and sex, the indirect (GrimAge-mediated) effect of neighborhood disadvantage was moderated by psychosocial risk such that for every standard deviation increase in negative affect the hazards of HF was 1.18 (95% confidence interval = 1.05, 1.36). No moderated mediation effect was detected for optimism. DISCUSSION: Findings support the necessity for multilevel interventions simultaneously addressing neighborhood and individual psychosocial risk in the reduction of HF among Black persons.

RESUMO

BACKGROUND: Racial disparities in atopic disease (atopic dermatitis [AD], asthma, and allergies) prevalence are well documented. Despite strong associations between race and socioeconomic deprivation in the United States, and socioeconomic status (SES) and atopic diseases, the extent to which SES explains these disparities is not fully understood. OBJECTIVE: We sought to identify racial disparities in childhood atopic disease prevalence and determine what proportion of those disparities is mediated by SES. METHODS: This study used the National Health Interview Survey (2011-2018) to investigate AD, asthma, and respiratory allergy prevalence in Black and White children and the extent to which measures of SES explain any identified disparities. RESULTS: By race, prevalences were as follows: AD, White 11.8% (95% CI: 11.4%, 12.2%) and Black 17.4% (95% CI: 16.6%, 18.3%); asthma prevalence, White 7.4% (95% CI: 7.0%, 7.7%) and Black 14.3% (95% CI: 13.5%, 15.0%); respiratory allergy, White 11.4% (95% CI: 11.0%, 11.9%) and Black 10.9% (95% CI: 10.3%, 11.6%). The percentage of the disparity between racial groups and disease prevalence explained by a multivariable measure of SES was 25% (95% CI: 15%, 36%) for Black versus White children with AD and 47% (95% CI: 40%, 54%) for Black versus White children with asthma. CONCLUSIONS: In a nationally representative US population, Black children had higher prevalence of AD and asthma than White children did and similar prevalence of respiratory allergy; a multivariable SES measure explained a proportion of the association between Black versus White race and AD and a much larger proportion for asthma.

RESUMO

OBJECTIVE: To examine how the effect of disadvantaged socioeconomic circumstances on the risk of paediatric infections is mediated by pregnancy smoking, excess weight during pregnancy and breast feeding in children under 5 years of age. DESIGN: A population-level, retrospective cohort study. The Swedish Medical Birth Register was combined with the National Patient Register, the longitudinal integration database for health insurance and labour market studies, the Cause of Death Register and a local register held by the Child Health Care Unit in Uppsala Region. SETTING: Uppsala Region, Sweden. PATIENTS: 63 216 term and post-term singletons born to women who resided in Uppsala Region, Sweden between 1997 and 2015. MAIN OUTCOME MEASURES: Number of hospital admissions for infectious diseases. Secondary outcomes were the number of hospitalisations for respiratory and enteric infections, respectively. RESULTS: The effect of disadvantaged socioeconomic circumstances, that is, low maternal education on the overall risk of paediatric infections was mediated to a considerable (33%-64%) proportion by pregnancy smoking, excess weight during pregnancy and breast feeding. CONCLUSIONS: Pregnancy smoking, excess weight during pregnancy and breast feeding mediate a considerable proportion of the association between deprived socioeconomic circumstances and paediatric infectious diseases. Therefore, inequalities in paediatric infectious diseases may be reduced by public health policies addressing these health-related behaviours.

RESUMO

BACKGROUND: The existing body of research exploring minority stressors and their impact on the mental health of Lesbian, Gay, and Bisexual (LGB) students in China remains limited in scope and often restricted to specific geographic regions.. METHODS: A combination of snowball and targeted sampling strategies was used to recruit lesbian, gay and bisexual students (N = 1,393) for a cross-sectional, online survey in China. Participants (Mage = 20.00 years; 60.23% assigned male at birth) were tasked with completing a comprehensive questionnaire designed to capture various dimensions, including gender expression, minority stressors (e.g., school bullying, internalized homophobia), social psychological resources (e.g., perceived social support), and mental health-related outcomes (e.g., depression, anxious and stress). Our analytical approach involved hierarchical multiple regression analyses, mediation and moderated mediation modeling to elucidate the intricate interplay among these factors. RESULTS: Our findings shed light on the pronounced mental health disparities afflicting LGB college students in China, with notable prevalence rates of depression (48.1%), anxiety (57.1%), and stress (37.5%). A significant positive correlation was observed between experiences of school-based victimization and internalized homophobia, which, in turn, exhibited a direct association with affective symptoms.School bullying was positive with internalized homophobia, which was positively associated with affective symptoms.In addition to unveiling the indirect effects of school bullying on affective symptoms, our study identified direct links in this complex relationship. Notably, the availability of social support emerged as a pivotal factor, serving as a moderator within the mediation model by mitigating the path from school-based victimization bullying to internalized homophobia (ß = -0.077, P = 0.040). CONCLUSIONS: This study underscores the pervasive and concerning mental health disparities experienced by LGB college students in China. In response, institutions of higher learning should intensify anti-bullying initiatives tailored to LGB students and implement comprehensive gender education programs. Moreover, concerted efforts should be directed at enhancing the accessibility of social support resources for LGB college students, with the aim of cultivating and sustaining favorable psychological well-being.

RESUMO

OBJECTIVES: There is evidence that both low socioeconomic status (SES) and psychosocial stressors at work (PSW) increase risk of depression, but prospective studies on the contribution of PSW to the socioeconomic gradient of depression are still limited. METHODS: Using a prospective cohort of Quebec white-collar workers (n = 9188 participants, 50% women), we estimated randomized interventional analogues of the natural direct effect of SES indicators at baseline (education level, household income, occupation type and a combined measure) and of their natural indirect effects mediated through PSW (job strain and effort-reward imbalance (ERI) measured at the follow-up in 1999-2001) on incident physician-diagnosed depression. RESULTS: During 3 years of follow-up, we identified 469 new cases (women: 33.1 per 1000 person-years; men: 16.8). Mainly in men, low SES was a risk factor for depression [education: hazard ratio 1.72 (1.08-2.73); family income: 1.67 (1.04-2.67); occupational type: 2.13 (1.08-4.19)]. In the entire population, exposure to psychosocial stressors at work was associated with increased risk of depression [job strain: 1.42 (1.14-1.78); effort-reward imbalance (ERI) 1.73 (1.41-2.12)]. The estimated indirect effects of socioeconomic indicators on depression mediated through job strain ranged from 1.01 (0.99-1.03) to 1.04 (0.98-1.10), 4-15% of total effects, and for low reward from 1.02 (1.00-1.03) to 1.06 (1.01-1.11), 10-15% of total effects. DISCUSSION: Our study suggests that PSW only slightly mediate the socioeconomic gradient of depression, but that socioeconomic inequalities, especially among men, and PSW both increase the incidence of depression.

RESUMO

AIM: To highlight correlations existing between incidence and mortality of pancreatic cancer, and health care indicators in 36 European countries. METHODS: The Global Burden of Disease (GBD) and Eurostat databases were queried between 2004 and 2019. Incidence and mortality were age-standardized. From Eurostat, indicators regarding expenditure, hospital beds, medical technology, health personnel, physicians by medical specialty and unmet needs for medical examination were extracted. Correlations between GBD and Eurostat data were analysed through mediation analysis applying clustering for countries. RESULTS: Incidence increased by +0.6% per year (p = 0.001) and mortality by +0.3% (p = 0.001), being increasing for most of the European countries considered. Incidence and mortality were strongly positively correlated (p = 0.001). Higher current health expenditure, expenditure in inpatient curative care, the number of available beds, the number of computed tomography scan, magnetic resonance units, practising medical doctors were all related to higher incidence (p < 0.05), whereas the unmet need for medical examinations was related to lower incidence. When the mediator' effect of incidence was handled, these indicators, together with expenditure on outpatient curative cares, the number of pet scanners and of radiation therapy equipment, were related to lower mortality (p < 0.05). CONCLUSIONS: Health care environment correlates with reported incidence and mortality of pancreatic cancer. This highlights both that ameliorated socio-economic societies suffer from higher incidence but lower mortality, as well as the epidemiological bias originating from countries' diagnostic ability.

RESUMO

BACKGROUND: Providing care for older adults has been associated with the presence of depressive symptoms among their informal caregivers. Numerous caregivers and older adults' characteristics have been mentioned as predictors of caregivers' depression. However, studies dealing with the impact of older adults' frailty status on caregivers' depression are scarce. This study was conducted to clarify the precise relationship between caregivers' depression, caregivers' burden, caregivers' characteristics and patients' characteristics, including frailty, among the variables that may have an impact on caregivers' depression. METHODS: In this cross-sectional study, patients and caregivers' characteristics were recorded for 311 patient-caregiver dyads, when the patient was admitted to the hospital. For the purpose of the study, a mediation analysis was used with patients and caregiver characteristics considered to be predictors, subjective caregivers' burden as the mediator, and caregivers' depression as the outcome variable. RESULTS: Only patients' frailty and caregivers' subjective burden had a direct effect on caregivers' depression. Moreover, caregivers' gender, patients' frailty status and comorbidity, duration of caregiving, and the relationship with the patient, had an indirect effect through caregivers' burden that acted as mediator. Regarding total effects, caregivers burden followed by patients' frailty status had the greater impact on caregivers' depression. CONCLUSIONS: By organising interventions to reduce caregivers' depression, patients' frailty status could be among the targets of those interventions considering that frailty might be delayed or reversed.

RESUMO

OBJECTIVES: The objective of the study was to investigate the contribution of work factors and health-related lifestyle to educational inequalities in physical health among older workers in Germany by applying causal mediation analysis with longitudinal data. METHODS: Data from the German lidA study was used. 2653 persons (53% female, 47% male) aged 46 (born 1965) and 52 (born 1959) at baseline were followed up for seven years with exposure and outcome assessments in 2011 (t0), 2014 (t1) and 2018 (t2). The total effect of education on physical health was decomposed into a natural direct effect (NDE) and a natural indirect effect (NIE) by using a sex-stratified causal mediation analysis with an inverse odds weighting approach. Baseline health, partner status and working hours were entered as a first set of mediators preceding the putative mediators of interest. All analyses were adjusted for age and migrant status. RESULTS: Independent of the first set of mediators, work factors explained 21% of educational inequalities in physical health between low and high educated women and 0% comparing moderate versus high educated women. The addition of health behaviors explained further 26% (low vs. high education) and 20% (moderate vs. high education), respectively. Among men, net of the first set of mediators, work factors explained 5% of educational inequalities in physical health between low and high educated and 6% comparing moderate versus high educated persons. Additional 24% (low vs. high education) and 27% (moderate vs. high education) were explained by adding health behaviors to the models. CONCLUSIONS: To reduce educational inequalities in physical health among older workers in Germany, interventions to promote healthy behaviors are promising. Improving working conditions is likely an important prerequisite.

RESUMO

BACKGROUND: Lower maternal education is associated with higher body mass index (BMI) and higher chronic inflammation in offspring. Childhood adversity potentially mediates these associations. We examined the extent to which addressing childhood adversity could reduce socioeconomic inequities in these outcomes. METHODS: We analysed data from two early-life longitudinal cohorts: the Longitudinal Study of Australian Children (LSAC; n=1873) and the UK Avon Longitudinal Study of Parents and Children (ALSPAC; n=7085). EXPOSURE: low/medium (below university degree) versus high maternal education, as a key indicator of family socioeconomic position (0-1 year). OUTCOMES: BMI and log-transformed glycoprotein acetyls (GlycA) (LSAC: 11-12 years; ALSPAC: 15.5 years). Mediator: multiple adversities (≥2/<2) indicated by family violence, mental illness, substance abuse and harsh parenting (LSAC: 2-11 years; ALSPAC: 1-12 years). A causal mediation analysis was conducted. RESULTS: Low/medium maternal education was associated with up to 1.03 kg/m2 higher BMI (95% CI: 0.95 to 1.10) and up to 1.69% higher GlycA (95% CI: 1.68 to 1.71) compared with high maternal education, adjusting for confounders. Causal mediation analysis estimated that decreasing the levels of multiple adversities in children with low/medium maternal education to be like their high maternal education peers could reduce BMI inequalities by up to 1.8% and up to 3.3% in GlycA. CONCLUSIONS: Our findings in both cohorts suggest that slight reductions in socioeconomic inequities in children's BMI and inflammation could be achieved by addressing childhood adversities. Public health and social policy efforts should help those affected by childhood adversity, but also consider underlying socioeconomic conditions that drive health inequities.

RESUMO

PURPOSE: Deprivation and segregation indices are often examined as possible explanations for observed health disparities in population-based studies. In this study, we assessed the role of recognized deprivation and segregation indices specifically as they affect survival in a cohort of self-identified Black women diagnosed with ovarian cancer who enrolled in the African American Cancer Epidemiology Study. METHODS: Mediation analysis was used to examine the direct and indirect effects between deprivation or segregation and overall survival via a Bayesian structural equation model with Gibbs variable selection. RESULTS: The results suggest that high socioeconomic status-related indices have an association with increased survival, ranging from 25% to 56%. In contrast, index of concentration at the extremes-race does not have a significant impact on overall survival. In many cases, the indirect effects have very wide credible intervals; consequently, the total effect is not well estimated despite the estimation of the direct effect. CONCLUSIONS: Our results show that Black women living in higher socioeconomic status neighborhoods are associated with increased survival with ovarian cancer using area-level economic indices such as Yost or index of concentration at the extremes-income. In addition, the Kolak urbanization index has a similar impact and highlights the importance of area-level deprivation and segregation as potentially modifiable social factors in ovarian cancer survival.

RESUMO

BACKGROUND: It is unknown whether financial well-being mediates the impact of multimorbidity on the health-related quality of life (HRQoL) of cancer patients. METHODS: Participants were recruited from three outpatient oncology clinics of Hong Kong public hospitals. Multimorbidity was assessed using the Charlson Comorbidity Index. Financial well-being, the mediator of the association between multimorbidity and HRQoL outcomes, was assessed using the Comprehensive Score for Financial Toxicity Functional Assessment of Chronic Illness Therapy. The HRQoL outcomes were assessed using the Functional Assessment of Cancer Therapy - General (FACT-G) and its four sub-dimensions. Mediation analyses were conducted using SPSS PROCESS v4.1. RESULTS: Six-hundred and forty cancer patients participated in the study. Multimorbidity had a direct effect on FACT-G scores independent of financial well-being (ß for path c' = -0.752, p < 0.001). In addition, multimorbidity had an indirect effect on FACT-G scores through its effect on financial well-being (ß for path a = -0.517, p < 0.05; ß for path b = 0.785, p < 0.001). Even after adjustments were made for the covariates, the indirect effect of multimorbidity on FACT-G via financial well-being remained significant, accounting for 38.0% of the overall effect, indicating partial mediation. Although there were no statistically significant associations between multimorbidity, social well-being, and emotional well-being, the indirect effects of multimorbidity on physical and functional well-being through financial well-being remained significant. CONCLUSIONS: Poor financial well-being attributable to multimorbidity partially mediates the direct impact of chronic conditions on HRQoL in Chinese cancer patients, particularly their physical and functional well-being.

BACKGROUND: Habitual Physical activity (HPA) is a non-pharmacological strategy to prevent and control chronic diseases, and it plays an important role in minimizing healthcare costs. OBJECTIVES: This study aimed to investigate the relationship between HPA and healthcare costs from the perspective of the Brazilian National Healthcare System, and to establish the mediating role of comorbidities in this relationship among patients with cardiovascular diseases (CVD). DESIGN AND SETTING: This longitudinal study was conducted in a medium-sized Brazilian city and included 278 participants assisted by the Brazilian National Healthcare System. METHODS: Information on healthcare costs were obtained from medical records and included primary, secondary, and tertiary levels. Comorbidities (diabetes, dyslipidemia, and arterial hypertension) were self-reported, and obesity was confirmed with the percentage of body fat. HPA was measured using a questionnaire (Baecke questionnaire). Face-to-face interviews provided information on sex, age, and education level. Statistical analysis included linear regression and Structural Equation Modeling, significance was set at 5 % and the Stata software (version 16.0) was used to perform the analysis. RESULTS: The sample included 278 adults with a mean age of 54.49 (8.32) years. For each score of HPA, there was a reduction in healthcare costs of US$ 83.99/24 months (95 % CI: - 159.15; - 8.84), and the sum of comorbidities did not mediate this relationship. CONCLUSION: It is concluded that healthcare costs seem to be affected by HPA among patients with CVD, while this phenomenon seems not to be mediated by the sum of comorbidities.

RESUMO

BACKGROUND: Recent literature has suggested that associations and interactions between family socioeconomic status (SES) and home food environment influence children's diet, but little is known about the mediation roles of parental role-modeling and food availability in the socioeconomic inequalities of children's diet. This study aimed to determine the associations between family SES and children's fruit and vegetable (FV) consumption and to assess the mediation roles of parental role-modeling and food availability in the above associations. METHODS: Cross-sectional data of 574 Finnish children (aged 3 to 6) were analyzed. Parents completed an FFQ assessing their children's FV consumption frequency and a questionnaire assessing SES and home food environment. Two exposure variables: parental educational level ("low", "middle", and "high") and the relative family income tertiles of the family were used. The frequencies of parental role-modeling of FV and sugary food and drink (SFD) consumption, and the availability of FV and SFD at home were calculated. Single- and multiple-mediator models were created using IBM SPSS 27.0. RESULTS: The positive association between high parental educational level and children's FV consumption (direct effect coefficient: 2.76, 95% CI: 0.51-4.86) was partially mediated by more frequent parental role-modeling of FV consumption (indirect effect coefficient: 0.89, 95% CI: 0.10-1.76), higher availability of FV (indirect effect coefficient: 1.00, 95% CI: 0.35-1.77), and lower availability of SFD (indirect effect coefficient: -0.30, 95% CI: -0.72 - -0.01). The relative family income was not directly associated with the outcome. However, the higher relative family income level indirectly predicted the Children's FV consumption (full mediation) through more frequent parental role-modeling of FV consumption (indirect effect coefficient: 0.91, 95% CI: 0.06-1.83) and higher availability of FV (indirect effect coefficient: 0.98, 95% CI: 0.40-1.67). Parental role-modeling on SFD consumption did not mediate any of the above associations. CONCLUSIONS: Parental educational level showed more associations with children's FV consumption than relative family income. Our findings suggest that reducing the availability of SFD is as important as increasing the availability of FV to enhance children's FV consumption. Future interventions to improve children's dietary behaviors should pay greater attention to the lower SES segments of society. Longitudinal studies and intervention studies supporting these findings are needed for making meaningful recommendations for health promotion.

RESUMO

Research has indicated that biological (self-regulation), psychological (temperament), and social (maternal parenting behaviors) factors predict childhood externalizing behaviors. Few studies, however, have evaluated psychological, biological, and social factors in conjunction as predictors of childhood externalizing behaviors. Further, limited research has examined whether these biopsychosocial predictors during infancy and toddlerhood predict the onset of externalizing behaviors in early childhood. The present study aimed to examine the longitudinal relations between biopsychosocial predictors of child externalizing behaviors. Children and their mothers (n = 410) participated when children were 5, 24, and 36 months old. Child self-regulation was assessed via baseline respiratory sinus arrhythmia (RSA) at age 5 months, and child psychology was measured via maternal report of effortful control at age 24 months. Additionally, maternal intrusiveness was assessed during a mother-child interaction at age 5 months. At 36 months, mothers reported on child externalizing behaviors. Longitudinal path modeling was used to examine the direct and indirect effects of maternal intrusiveness and child effortful control on child externalizing behavior, as well as whether these effects were conditional upon child baseline RSA. Results showed a significant indirect effect of maternal intrusiveness on externalizing behavior through effortful control, and this pathway was moderated by baseline RSA after controlling for orienting regulation at age 5 months. These results suggest that early childhood externalizing behaviors are jointly affected by biological, psychological, and social factors during toddlerhood.
