A mixed-methods longitudinal examination of weight-related self-monitoring and disordered eating among a population-based sample of emerging adults.

BACKGROUND: Weight-related self-monitoring (WRSM) apps are used by millions, but the effects of their use remain unclear. This study examined longitudinal relationships between WRSM and disordered eating among a population-based sample of emerging adults. METHODS: Participants (n = 138) were recruited from EAT 2010-2018 (Eating and Activity over Time study) to participate in a mixed-methods (quantitative and qualitative) longitudinal study to understand the impacts of WRSM. In 2018, participants (Mage=21.7 ± 1.9 years) reported motivations for use and types of WRSM apps used. Dependent variables collected in 2022 (Mage=25.7 ± 1.9 years) included past year total number of disordered weight control behaviors, disordered muscle building behaviors, compulsive exercise, and binge eating. Linear and logistic regressions were used adjusting for sociodemographics, body mass index, and baseline disordered eating. Semi-structured interviews (n = 25) were analyzed using inductive thematic analysis. RESULTS: Participants using WRSM apps for weight management demonstrated an increase in disordered weight control behaviors over time (ß = 0.894, p = .012). Using WRSM apps for "healthy" eating was marginally associated with an increase in disordered weight control behaviors. (ß = 0.673, p = .052). Qualitatively, participants reported varied temporality between WRSM and disordered eating, but believed that app use encouraged restriction/binge cycles and normalized disordered eating. CONCLUSIONS: Findings suggest there may be individual variation in the relationships between WRSM and disordered eating, but that using WRSM apps with the motivation of managing eating or weight may increase disordered eating in some. Additionally, WRSM apps may normalize or encourage disordered eating. Therefore, safeguards, including screening and monitoring, are needed to ensure WRSM does not cause or escalate harm among WRSM users.

For some, weight-related self-monitoring apps, like MyFitnessPal and Fitbit, may cause or worsen disordered eating over time among emerging adults. However, it seems as though the motivation for self-monitoring (e.g., for managing eating or weight) may be more important than what they are monitoring when it comes to disordered eating risk.

Harmonizing the Tripartite Mission in Academic Family Medicine: A Longitudinal Case Example.

Academic practices and departments are defined by a tripartite mission of care, education, and research, conceived as being mutually reinforcing. But in practice, academic faculty have often experienced these 3 missions as competing rather than complementary priorities. This siloed approach has interfered with innovation as a learning health system in which the tripartite missions reinforce each other in practical ways. This paper presents a longitudinal case example of harmonizing academic missions in a large family medicine department so that missions and people interact in mutually beneficial ways to create value for patients, learners, and faculty. We describe specific experiences, implementation, and examples of harmonizing missions as a feasible strategy and culture. "Harmonized" means that no one mission subordinates or drives out the others; each mission informs and strengthens the others (quickly in practice) while faculty experience the triparate mission as a coherent whole faculty job. Because an academic department is a complex system of work and relationships, concepts for leading a complex adaptive system were employed: (1) a "good enough" vision, (2) frequent and productive interactions, and (3) a few simple rules. These helped people harmonize their work without telling them exactly what to do, when, and how. Our goal here is to highlight concrete examples of harmonizing missions as a feasible operating method, suggesting ways it builds a foundation for a learning health system and potentially improving faculty well-being.

Understanding the relationships between acculturation, food insecurity, and food parenting practices among socioeconomically/racially diverse parents.

Research suggests that acculturation and food insecurity are factors that are separately associated with the use of specific food parenting practices among United States (US) families. Certain food parenting practices, such as coercive control and unstructured food parenting practices, are related to negative health consequences in children, such as disordered eating behaviors. The current study aimed to explore associations between acculturation strategies and food parenting practices in a sample of 577 Latinx, Hmong, Somali/Ethiopian, and Multiracial families. A secondary objective was to understand whether food security status significantly modified the relationships between acculturation strategies and food parenting practices. Results showed that acculturation strategies were significantly related to food parenting practices, and patterns in these relationships differed across race and ethnicity. Further, food security status significantly modified the relationship between acculturation strategies and food parenting practices for Latinx, Hmong, and Somali/Ethiopian families, but not for Multiracial families. These results point to the complex relationships among acculturation strategies, food security status, and food parenting practices in immigrant populations in the US. Longitudinal studies exploring the temporal relationships between acculturation strategies, food security status, and food parenting practices would help tease apart how food parenting practices may evolve upon migrating to the US.

Spillover from parent stress to family meals among diverse families: An ecological momentary assessment study.

Family meals are beneficial for youth healthy development. However, parents' experiences of daily stressors may hinder their capacity to facilitate family meals, serve healthful foods, and have implications for the family meal atmosphere. Using data from ecological momentary assessment, we examined whether family meals are less likely to occur, meals are less healthful, and meal atmosphere is less positive on days when parents experience higher-than-usual stress and whether coparenting support buffers these associations. We also explored the role of family stressors in these links. Participants were 497 parents (Mage = 35.86 years; 91% female) of 5- to 9-year-old children who identified as Asian (15%), Black (17%), Hispanic (10%), Native American (10%), Native Hawaiian (< 1%), White (38%), multiracial (8%), or other (< 1%). Results from multilevel models indicated that daily deviations in parents' stress levels were not correlated with family meal occurrence, healthfulness, or positive atmosphere. However, on days when the source of parents' stress was family related (e.g., family demands), odds of a positive meal atmosphere were significantly lower (OR = 0.92, 95% CI [0.88, 0.96]), adjusting for other sources of stress. Coparenting relationship quality was positively associated with family meal occurrence (OR = 1.34, 95% CI [1.01, 1.79]) and healthfulness (γ = 0.20, p < .001), however, it did not moderate links between stress and family meal occurrence, healthfulness, or atmosphere. Findings suggest that day-to-day fluctuations in parents' stress levels may not disrupt whether a family meal occurs, the healthfulness of foods served, or the atmosphere of family meals. However, family stressors and coparenting relationship quality merit investigation as potential intervention targets. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
