BACKGROUND: Early life socioeconomic disadvantage and adverse experiences may lead to overeating, which is in turn associated with increased body mass index (BMI). However, recent evidence indicated that the association between childhood BMI and overeating might be bidirectional. This bidirectionality prompts the need for further investigation of early life predictors of BMI in childhood. OBJECTIVES: To longitudinally assess the directionality of the association between childhood BMI and perceived overeating and to investigate their antecedent early life predictors. METHODS: The sample included data from 5151 children from the ELSPAC study, collected between 18 months and 11 years of child age. The outcomes were child BMI and mother-reported overeating, assessed at the age of 3, 5, 7 and 11 years. Predictors included maternal BMI, maternal education, single parenthood, financial difficulties and adverse childhood experiences (ACEs) reported by parents and paediatricians. The random intercept cross-lagged panel model was applied. RESULTS: The mean child's BMI at age 3 was 15.59 kg/m2 and increased to 17.86 kg/m2 at age 11. The percentage of parent-reported overeating increased in the following period, from about 12% at age 3 to 17% at age 11. The results showed temporal stability in perceived overeating and BMI, with a bidirectional relationship strengthening over time. The child's BMI was associated with maternal BMI. Maternal BMI was positively associated with child-perceived overeating, but a stronger effect was found for ACEs. ACEs mediated the impact of maternal education, financial difficulties and single parenthood on overeating. CONCLUSIONS: We observed stable bidirectional associations between BMI and perceived overeating. The results indicated two main pathways: one linked to maternal BMI and early childhood BMI increase followed by perceived overeating and the second associated with ACEs mediating the effect of early childhood social factors on perceived overeating, leading to gradual BMI gain.

BACKGROUND: The online environment provides adolescents with vast amounts of health-related information; however, navigating this effectively requires high levels of eHealth literacy to avoid misinformation and harmful content. Parental guidance is often considered a crucial factor in shaping adolescents' online health behaviors; however, there is limited longitudinal research examining how parental eHealth literacy mediation influences adolescents' development of eHealth literacy over time. OBJECTIVE: This study aims to examine the reciprocal relationship between parental eHealth literacy mediation and adolescents' eHealth literacy. It also investigates whether parental education moderates this relationship, specifically exploring whether higher levels of parental education enhance the effectiveness of eHealth literacy mediation in improving adolescents' eHealth literacy. METHODS: A 3-wave longitudinal study was conducted, collecting data from 2500 adolescent-parent pairs. A random intercept cross-lagged panel model was applied to assess the reciprocal effects between parental eHealth literacy mediation and adolescents' eHealth literacy across the 3 waves. Parental education was included in the model as a potential moderating variable to examine whether it influences the strength of the relationship between parental eHealth literacy mediation and adolescents' eHealth literacy. RESULTS: The findings revealed no significant within-person effects, indicating that changes in parental eHealth literacy mediation over time did not lead to corresponding changes in adolescents' eHealth literacy (T1→T2 β=-.03, P=.65; T2→T3 β=.01, P=.84), and vice versa (T1→T2 β=.02, P=.71; T2→T3 β=-.07, P=.19). Furthermore, the data did not support a moderating effect of parental education, suggesting that higher educational attainment does not enhance the impact of parental eHealth literacy mediation. However, a significant between-person association was observed: adolescents with higher levels of eHealth literacy tend to have parents who engage more frequently in eHealth literacy mediation (r=0.30, P<.001). CONCLUSIONS: This study contributes to the understanding of parental involvement in shaping adolescents' eHealth literacy. Contrary to expectations, parental eHealth literacy mediation does not appear to have a significant longitudinal impact on the development of adolescents' eHealth literacy, nor does higher parental education strengthen this relationship. These findings suggest that additional factors beyond parental mediation and education may play a critical role in supporting adolescents' ability to navigate online health information effectively.
BACKGROUND: Longitudinal investigation of the association between mobile health (mHealth) app use and attitudes toward one's body during adolescence is scarce. mHealth apps might shape adolescents' body image perceptions by influencing their attitudes toward their bodies. Adolescents might also use mHealth apps based on how they feel and think about their bodies. OBJECTIVE: This prospective study examined the longitudinal within-person associations between mHealth app use, body dissatisfaction, and physical self-worth during adolescence. METHODS: The data were gathered from a nationally representative sample of Czech adolescents aged between 11 and 16 years (N=2500; n=1250, 50% girls; mean age 13.43, SD 1.69 years) in 3 waves with 6-month intervals. Participants completed online questionnaires assessing their mHealth app use, physical self-worth, and body dissatisfaction at each wave. The mHealth app use was determined by the frequency of using sports, weight management, and nutritional intake apps. Physical self-worth was assessed using the physical self-worth subscale of the Physical Self Inventory-Short Form. Body dissatisfaction was measured with the items from the body dissatisfaction subscale of the Eating Disorder Inventory-3. The random intercept cross-lagged panel model examined longitudinal within-person associations between the variables. A multigroup design was used to compare genders. Due to the missing values, the final analyses used data from 2232 adolescents (n=1089, 48.8% girls; mean age 13.43, SD 1.69 years). RESULTS: The results revealed a positive within-person effect of mHealth app use on the physical self-worth of girls: increased mHealth app use predicted higher physical self-worth 6 months later (β=.199, P=.04). However, this effect was not consistent from the 6th to the 12th month: a within-person increase in using apps in the 6th month did not predict changes in girls' physical self-worth in the 12th month (β=.161, P=.07). Regardless of gender, the within-person changes in the frequency of using apps did not influence adolescents' body dissatisfaction. In addition, neither body dissatisfaction nor physical self-worth predicted app use frequency at the within-person level. CONCLUSIONS: This study highlighted that within-person changes in using mHealth apps were differentially associated with adolescents' body-related attitudes. While increased use of mHealth apps did not influence body dissatisfaction across genders, it significantly predicted higher physical self-worth in adolescent girls 6 months later. A similar association was not observed among boys after 6 months. These findings indicate that using mHealth apps is unlikely to have a detrimental impact on adolescents' body dissatisfaction and physical self-worth; instead, they may have a positive influence, particularly in boosting the physical self-worth of adolescent girls.

INTRODUCTION: Initial evidence suggests that engaging with accepting communities on social media such as Instagram may inform sexual minority youths' sense of stigma and well-being. However, as existing research has predominately drawn upon cross-sectional or qualitative designs, it is currently unclear whether the positive experiences identified in previous research accumulate, endure, or evolve over time. We also know relatively little about whether engagement with accepting online communities is primarily a compensatory or enhancing behavior. Thus, drawing upon minority stress theory and broaden-and-build theory, this study explores the longitudinal reciprocal relationships between perceived stigma, well-being, and engagement with accepting Instagram communities. METHOD: Three-wave panel data were collected from 460 sexual minority youth in the United States and Poland (M age = 18.58, SD = 1.64), and data were analyzed using a random intercept cross-lagged panel model. RESULTS: At the between-person level, engagement with accepting Instagram communities was positively associated with perceived stigma and negatively associated with well-being. No significant within-person associations emerged between perceived stigma and engagement with accepting Instagram networks. However, a positive reciprocal relationship was found between well-being and engagement with accepting Instagram communities. Cultural context had no moderating effect on the hypothesized model. CONCLUSIONS: Results suggest that whilst the interrelations between perceived stigma and engaging with accepting online networks may be short-lived, engaging with supportive Instagram communities may contribute to an upward spiral of positive emotions. Findings therefore extend the existing literature regarding the potential benefits of social media use amongst sexual minority youth.

BACKGROUND: We aimed to disentangle within-person and between-person effects in the temporal relationship between depressive symptoms and cognitive function. METHODS: We performed a prospective population-based cohort study on participants of the Survey of Health, Ageing and Retirement in Europe. Cognitive function was assessed by tests on verbal fluency, immediate recall and delayed recall. Depressive symptoms were measured with EURO-D scale. To determine the temporal order of the association between cognitive function and depressive symptoms, we employed the fully saturated cross-lagged panel model (between-person effects), and random intercept cross-lagged panel model (within-person effects). RESULTS: In 59,311 participants (mean age 65, ranging 46-100), between-person effects showed a bi-directional relationship that could be seen in three stages: First, the effect of cognitive function on depressive symptoms was initially slightly stronger than vice versa. Second, the effect of depressive symptoms on cognitive function became stronger during the follow-up. Third, all effects were small and no direction dominated. Within-person effects, however, revealed a dominant effect from depressive symptoms on cognitive function. Some effects from cognitive function on depressive symptoms were apparent only in older adults, in particular men. All effects were small and strongest for individuals aged 65 years and above. LIMITATIONS: The sample is healthier than general population and thus not fully representative. A comprehensive cognitive battery was not available. CONCLUSIONS: Long-term relationship between depressive symptoms and cognitive function is bi-directional. However, to achieve improvement in an individual in the short-term, the focus should be on decreasing depressive symptoms to improve cognitive function.
