Supporting family meal frequency: Screening Phase results from the Simply Dinner Study.

We aimed to test main, additive, interactive effects, and feasibility of all possible combinations of six intervention components implemented for 8 weeks (Cooking/Serving Resources; Meal Delivery; Ingredient Delivery; Community Kitchen; Nutrition Education; Cooking Demonstrations). Primary outcomes were family meal frequency and preschoolers' dietary quality; secondary outcomes included family meal preparation type, meal preparation barriers, family functioning, and kitchen inventory adequacy. All possible intervention combinations were tested using a randomized factorial trial design in the first phase of a Multiphase Optimization Strategy (MOST). Feasibility was assessed via attendance, delivery logs, and satisfaction. Parent-reported data collection included: socio-demographics, frequency and type of family meals; preschooler dietary intake; perceived barriers to meal planning and preparation; assessment of family functioning; and a kitchen inventory of materials generally needed for meal preparation. Participants (n = 499) were recruited at two Head Start agencies in mid-Michigan with data collection and delivery of some intervention components in participants' homes. Promising intervention bundles were identified by evaluating pre-to post-intervention effect sizes. The combination of Cooking/Serving Resources and Meal Delivery increased family meal frequency (Cohen's d = 0.17), cooking dinner from scratch (d = 0.21), prioritization of family meals (d = 0.23), and kitchen inventory (d = 0.46) and decreased use/consumption of ready-made (d = -0.18) and fast foods (d = -0.23). Effects on diet quality were in the expected direction but effect sizes were negligible. Community Kitchen, Nutrition Education, and Cooking Demonstration showed poor feasibility due to low attendance while Ingredient Delivery was infeasible due to staffing challenges related to its labor intensity. Additionally, although not one of our pre-specified outcomes, Cooking/Serving Resources (RR = 0.74) and Meal Delivery (RR = 0.73) each decreased food insecurity. Cooking/Serving Resources combined with Meal Delivery showed promise as a strategy for increasing family meal frequency.

A pilot evaluation of the Building Early Emotional Skills (BEES) curriculum in face-to-face and online formats.

The Building Early Emotional Skills (BEES) parenting program is designed to promote parent-child relationships and more optimal social-emotional development by addressing four sequentially built skills in parenting infants/toddlers: (1) building parental awareness of emotions in self and child; (2) listening and interacting sensitively; (3) identifying and labeling emotions; and (4) intentionally supporting early self-regulation skills. BEES used an 8-session format delivered in online or face-to-face platforms (N = 264 female caregivers; n = 214 online, n = 50 face-to-face). Linear mixed modeling for pre-to-post changes showed significant increases in knowledge, emotion coaching beliefs, acceptance of negative emotions, and self-reported emotionally supportive responses to emotions; and, significant decreases in rejection of emotions, emotionally unsupportive responses, and parenting distress. Results suggested no differences in rate of change by program delivery type. Caregivers with more depressive symptoms showed greater improvement in their parenting distress. The BEES program may be a tool to support early positive parenting.

Intervention Effects of "Girls on the Move" on Increasing Physical Activity: A Group Randomized Trial.

BACKGROUND: Limited intervention success in increasing and sustaining girls' moderate-to-vigorous physical activity (MVPA) underscores a need for continued research. PURPOSE: The aim of this study was to evaluate the effect of a 17-week Girls on the Move (GOTM) intervention on increasing MVPA among fifth- to eighth-grade girls. METHODS: This study is a group (cluster) randomized trial, including 24 schools, pair matched and assigned to intervention (n = 12) or control (n = 12) conditions. Participants included 1,519 girls in racially diverse public schools in urban, underserved areas of the Midwestern USA. The intervention included three components: (i) 90-min after-school physical activity (PA) club offered 3 days/week; (ii) two motivational, individually tailored counseling sessions; and (iii) an interactive Internet-based session at the midpoint of the intervention. Main outcome measures were weighted mean minutes of MVPA per week post-intervention and at 9-month follow-up measured via accelerometer. RESULTS: No between-group differences occurred for weighted mean minutes of MVPA per week at post-intervention (B = -0.08, p = .207) or 9-month follow-up (B = -0.09, p = .118) while controlling for baseline MVPA. CONCLUSIONS: Research is needed to identify interventions that assist girls in attaining and maintaining adequate PA. CLINICALTRIALS.GOV IDENTIFIER: NCT01503333.

A Person-Centered Approach to Child Temperament and Parenting.

The aim of this study was to examine how variations in children's temperamental reactivity and mothers' parenting stress relate to parenting behavior. A sample of 3,001 mother-child dyads was assessed when children were 14, 24, 36, and 54 months. Latent profile analysis identified a group of temperamentally "easy" children whose mothers experienced little parenting stress, along with two groups of highly reactive children differentiated by mothers' stress levels. Maternal negative regard over time was highest in the group of reactive children with highly stressed mothers. Mothers in this group also perceived more child behavior problems and had less knowledge of child development. Results are discussed relative to Person × Environment interactions and the complex interplay between parent and child characteristics.

Sources and Types of Social Support for Physical Activity Perceived by Fifth to Eighth Grade Girls.

BACKGROUND: Information is lacking on forms and sources of social support for physical activity (PA) received by adolescent girls during various pubertal stages. Two study purposes were to (a) identify the sources and forms of social support for PA perceived by adolescent girls, and (b) examine associations of pubertal stage and social support with PA. METHODS: A secondary analysis of data from a randomized trial was conducted. Fifth through eighth grade girls (N = 1,519) completed surveys on social support for PA and pubertal stage and wore an accelerometer. RESULTS: Girls in early-middle and late-post puberty most frequently received social support from their mothers. A higher proportion of girls in late-post puberty, compared to early-middle puberty, received social support from nonfamily adults (4.2% vs. 3.0%, p = .019). Girls identifying three sources participated in more moderate-to-vigorous PA than those having fewer sources (t1,512 = -3.57, p < .001). Various forms of social support, except for encouragement, were positively related to moderate-to-vigorous PA. Girls in early-middle puberty reported greater social support than those in late-post puberty (t1,512 = 3.99, p < .001). Social support was positively associated with moderate-to-vigorous PA, while girls in late-post puberty had lower moderate-to-vigorous PA than those in early-middle puberty. CONCLUSIONS: Mothers are important sources of social support for PA. Having more than two sources may result in greater PA. Encouraging girls to increase their PA may not be sufficient. CLINICAL RELEVANCE: Efforts are needed from health professionals to prevent any decline in social support for PA as girls advance across adolescence.

Longitudinal associations between parental reflective functioning and maternal mind-mindedness.

Little work has examined longitudinal associations between parental reflective functioning (PRF) and mind-mindedness (MM), limiting the understanding of separate or bidirectional trajectories of these related but distinct forms of mentalization. We examined cross-lagged associations between PRF, assessed via interview, and MM, coded from play interactions, over 12 months among 90 parents (86% female; 57% White, 43% Black) of infants (Mage = 10.56 months, SD = 8.20) who were participating in The Michigan Model of Infant Mental Health Home Visiting. Data were collected at study enrollment Time 1 (T1) and at 6-month Time 2 (T2) and 12-month Time 3 (T3) postenrollment. Mind-minded comments were coded as appropriate, reflecting accurate interpretation of mental states or nonattuned, characterizing inaccurate interpretations. PRF and appropriate MM each remained stable over time. PRF at the T1 positively predicted appropriate MM at T2. No other cross-lagged associations between PRF and appropriate MM were significant. Concurrent correlations between appropriate MM and PRF were significant only at T3. Nonattuned MM showed stability from T1 to T2 but nonattuned MM at the T2 did not predict nonattuned MM at T3. Greater PRF at T1 predicted less nonattuned MM at T2. No other cross-lagged associations between PRF and nonattuned MM were significant. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Cardiorespiratory Fitness as a Mediator of the Association between Physical Activity and Overweight and Obesity in Adolescent Girls.

Background: Overweight and obesity (OW/OB) continue to be prominent health issues among adolescent girls. However, little is known about the interrelationships between physical activity (PA), cardiorespiratory fitness (CRF), and OW/OB in this population. The objective of this study was to examine whether CRF mediates the relationship between PA and OW/OB in adolescent girls. Methods: Moderate-to-vigorous PA (MVPA), CRF, BMI, and percentage body fat (% BF) were measured in adolescent girls (N = 1519), aged 10-14 years, from 24 urban middle schools located in the Midwestern United States. Structural equation modeling was used to determine whether CRF is a mediator of the association between MVPA and OW/OB (measured as both BMI and % BF). Multigroup analyses were used to determine whether race, puberty, or socioeconomic status moderate the mediation models. Results: The indirect effect of MVPA through CRF on OW/OB was significant for both BMI (p < 0.01) and % BF (p < 0.01), indicating that CRF is a complete mediator between MVPA and OW/OB. Both race and puberty significantly (p < 0.05) moderated the mediation between MVPA and OW/OB. Conclusions: This study demonstrates that CRF is improved by increasing MVPA, and the improvement in CRF results in lower BMI and % BF among adolescent girls.

Effects of the Girls on the Move randomized trial on adiposity and aerobic performance (secondary outcomes) in low-income adolescent girls.

BACKGROUND: Limited, mixed evidence exists regarding the effectiveness of physical activity interventions on adiposity and aerobic performance in adolescent underrepresented populations. OBJECTIVE: To examine effects of Girls on the Move on body mass index z-scores (BMI-z), percent (%) body fat, and aerobic performance in fifth- to eighth-grade underrepresented girls. METHODS: A group randomized trial, involving 12 intervention and 12 control schools in low-income areas, was conducted. Participants (n = 1519) were low-active girls. The 17-week intervention included (a) a physical activity club, (b) two motivational interviewing sessions, and (c) one Internet-based session. BMI-z was determined from measured height and weight; % body fat was assessed using bioelectric impedance. Aerobic performance was assessed using a shuttle run. Demographics, physical activity (accelerometer), and pubertal development were assessed. Linear mixed models, adjusting for baseline, were used to examine group differences in postintervention. RESULTS: No significant between-group differences in BMI-z existed at postintervention, but % body fat increased less among intervention than control group girls (Mchange = 0.43% vs 0.73%). Aerobic performance decreased less in intervention vs control (Mchange = -0.39 vs -0.57). CONCLUSIONS: Although the intervention positively impacted % body fat and aerobic performance in underrepresented girls, more research is necessary to determine optimal implementation for yielding greater effects.

Toddlers with Early Behavioral Problems at Higher Family Demographic Risk Benefit the Most from Maternal Emotion Talk.

OBJECTIVE: To test the hypothesis that toddlers at highest risk for behavioral problems from the most economically vulnerable families will benefit most from maternal talk about emotions. METHODS: This study included 89 toddlers and mothers from low-income families. Behavioral problems were rated at 2 time points by masters-level trained Early Head Start home visiting specialists. Maternal emotion talk was coded from a wordless book-sharing task. Coding focused on mothers' emotion bridging, which included labeling emotions, explaining the context of emotions, noting the behavioral cues of emotions, and linking emotions to toddlers' own experiences. Maternal demographic risk reflected a composite score of 5 risk factors. RESULTS: A significant 3-way interaction between Time 1 toddler behavior problems, maternal emotion talk, and maternal demographic risk (p = .001) and examination of slope difference tests revealed that when maternal demographic risk was greater, more maternal emotion talk buffered associations between earlier and later behavior problems. Greater demographic risk and lower maternal emotion talk intensified Time 1 behavior problems as a predictor of Time 2 behavior problems. The model explained 54% of the variance in toddlers' Time 2 behavior problems. Analyses controlled for maternal warmth to better examine the unique contributions of emotion bridging to toddlers' behaviors. CONCLUSION: Toddlers at highest risk, those with more early behavioral problems from higher demographic-risk families, benefit the most from mothers' emotion talk. Informing parents about the use of emotion talk may be a cost-effective, simple strategy to support at-risk toddlers' social-emotional development and reduce behavioral problems.
