Associations of regular consumption of breakfast, lunch and dinner with Body Mass Index during adolescence: longitudinal findings by weight status among the Eating and Activity over Time 2010-2018 cohort.

OBJECTIVE: To examine how the associations between meal consumption and BMI over 8 years differ by weight status in a sample of adolescents. DESIGN: Longitudinal, population-based study. Breakfast, lunch and dinner consumption and BMI were self-reported. Linear regressions were used to examine how the associations between meal consumption and BMI differed by weight status. SETTING: Adolescents in the Minneapolis/St. Paul metropolitan area. PARTICIPANTS: Adolescents (n 1,471) were surveyed as part of the EAT 2010-2018 in 2009-2010 (Mage = 14·3 years) and 2017-2018 (Mage = 22·0 years). RESULTS: The prevalence of regular breakfast, lunch and dinner consumption (≥ 5 times/week) ranged from 45 to 65 %, 75 to 89 % and 76 to 94 %, respectively, depending on weight status category. Among adolescents with a sex- and age-specific BMI < 15th percentile, regular consumptions of breakfast, lunch and dinner during adolescence were positively associated with BMI in emerging adulthood compared with irregular consumption of breakfast, lunch and dinner (<5 times/week) after adjustment for socio-demographic characteristics (ß = 5·43, ß = 5·39 and ß = 6·46, respectively; all P-values <0·01). Among adolescents in the BMI 15-85th and 85-95th percentiles, regular consumptions of breakfast, lunch and dinner were positively associated with BMI but to a lesser extent (P-values <0·01). For participants with a BMI ≥ 95th percentile, regular consumptions of breakfast, lunch and dinner were positively associated with BMI, but the associations were not statistically significant (P-values > 0·05). CONCLUSIONS: The relationship between meal consumption during adolescence and BMI in emerging adulthood differs by adolescent weight status. Future studies should investigate underlying factors related to meal consumption routines and BMI.

Receiving gestational weight gain recommendations and associated risks: A qualitative study among low-income women.

Appropriate weight gain goals promote healthy gestational weight gain (GWG). Despite receiving recommendations from their providers, most women do not know how much weight they should gain during pregnancy. This study sought to describe the experiences of pregnant women when given GWG recommendations. The research proceeded using a phenomenological approach. With Institutional Review Board approval, primigravida women with a healthy singleton pregnancy at 8-20 weeks gestation were recruited from the community and purposively from a low-income obstetrics clinic. Within 60-minutes, trained interviewers 1) presented GWG recommendations and associated risks; and 2) interviewed participants using a semi-structured guide. Participants received a $40 gift card. Interviews were recorded and transcribed. Two trained coders used Braun and Clarke's (2020) reflexive thematic analysis procedures. When presented with GWG information, participants (n = 29, Mage = 25.5, 4.7 SD) proceeded to: 1) make sense of the information, 2) evaluate the credibility of the information, 3) weigh the importance of the information, 4) predict likely outcomes, and 5) plan behaviors. Participants who were able to understand the information, found it to be credible and important, and who predicted adverse outcomes for failing to adhere to recommendations reported intentions for health promoting behaviors. Future research should test GWG counseling methods based on these cognitive processes. Clinicians should consider these 5 cognitive processes when providing initial GWG counseling.

Exploring Factors Associated With Accelerometer Validity Among Ethnically Diverse Toddlers.

PURPOSE: Studying physical activity in toddlers using accelerometers is challenging due to noncompliance with wear time (WT) and activity log (AL) instructions. The aims of this study are to examine relationships between WT and AL completion and (1) demographic and socioeconomic variables, (2) parenting style, and (3) whether sedentary time differs by AL completion. METHODS: Secondary analysis was performed using baseline data from a community wellness program randomized controlled trial for parents with toddlers (12-35 mo). Parents had toddlers wear ActiGraph wGT3x accelerometers and completed ALs. Valid days included ≥600-minute WT. Analysis of variance and chi-square analyses were used. RESULTS: The sample (n = 50) comprised racial and ethnically diverse toddlers (mean age = 27 mo, 58% male) and parents (mean age = 31.7 y, 84% female). Twenty-eight families (56%) returned valid accelerometer data with ALs. Participants in relationships were more likely to complete ALs (P < .05). Toddler sedentary time did not differ between those with ALs and those without. CONCLUSIONS: We found varied compliance with WT instructions and AL completion. Returned AL quality was poor, presenting challenges in correctly characterizing low-activity counts to improve internal validity of WT and physical activity measures. Support from marital partners may be important for adherence to study protocols.

Exploring the prevalence of antidepressant medication discontinuation among pregnant veterans.

US female veterans have higher rates of mental health (MH) disorders compared to US civilian females and, consequently, are at risk for poor MH outcomes during pregnancy. This study evaluated the MH burden and identified the prevalence of antidepressant prescription and discontinuation among pregnant veterans (PGVets). The electronic health records (EHR) of PGVets using the US Veterans Administration's (VA) maternity care benefits over a two-year period were retrospectively reviewed. Inclusion criteria for this study were a current MH diagnosis of depression, anxiety, or posttraumatic stress disorder (PTSD) at the onset of pregnancy (n=351). Outcomes examined included antidepressant use prior to pregnancy, the use and discontinuation of antidepressants during pregnancy, and risk factors for discontinuation. PGVets had a high MH burden, as indicated by multiple comorbid diagnoses of unipolar depression, anxiety, and PTSD in 67% of the sample. At the onset of pregnancy, 163 (46%) were treated with an antidepressant. Only 56 (34%) continued using antidepressants through the pregnancy. Self-discontinuation (34%) and VA provider discontinuation (31%) of antidepressants were found. Among PGVets with documented past suicidal behaviors, 90% discontinued their active antidepressants. PGVets with indicators for more severe MH diagnoses were most likely to discontinue. The MH burden of PGVets and high rates of antidepressant discontinuation have implications for engaging this population in a higher level of perinatal monitoring and intervention. The findings suggest that VA providers and veterans would benefit from risks and benefits education regarding antidepressant use during pregnancy as well as the provision of alternative therapies.

Sex and ethnic/racial differences in disordered eating behaviors and intuitive eating among college student.

Introduction: Eating behaviors encompass disordered eating behaviors (e.g., overeating, binge eating, and associated symptoms of binge eating) and intuitive eating. Certain disordered eating behaviors, including binge eating, are more prevalent among female and ethnic/racial-minority college students than male and/or non-Hispanic White college students. However, sex and ethnic/racial differences among college students with other disordered eating (e.g., associated symptoms of binge eating) and intuitive eating behaviors remain unclear. Methods: In 2022, 887 college students (Mage = 20.9 ± 2.6 years) self-reported their sex, ethnicity/race, disordered eating behaviors (e.g., overeating, binge eating, associated symptoms of binge eating), and intuitive eating. To examine sex and ethnic/racial differences among these students, we used modified Poisson regressions for students who reported disordered eating and linear regressions for students who reported intuitive eating. Results: Except for overeating, disordered eating behaviors were more prevalent among female [adjusted prevalence ratio (aPR) = 1.3-1.8] than male college students after adjusting for sociodemographic variables, whereas intuitive eating scores did not differ by sex. Across ethnic/racial groups, disordered eating was more prevalent among all ethnic/racial-minority college students (aPR = 1.2-2.3) than non-Hispanic White college students after adjusting for sociodemographic variables. Moreover, non-Hispanic Black or African American college students had higher intuitive eating scores than non-Hispanic White college students (adjusted ß = 0.7, 95% CI = -0.2, 1.6). Conclusion: In our sample, notable differences emerged in the prevalence of disordered eating behaviors and mean scores by sex and ethnicity/race, while differences in intuitive eating scores emerged based on ethnicity/race.

Associations of positive childhood experiences with binge-eating disorder characteristics and intuitive eating among college students.

Childhood experiences encompass both adverse and positive childhood events. Adverse childhood experiences are positively associated with binge-eating disorder characteristics and inversely associated with intuitive eating in adults. However, to what extent positive childhood experiences (PCEs) are associated with binge-eating disorder characteristics and intuitive eating remains unclear. This study examined the associations of cumulative and individual PCEs with binge-eating disorder characteristics and intuitive eating among college students. Data were collected from 828 college students in 2022 (54.5% female, Mage 20.9 ± 2.6 years). PCEs were assessed using the Benevolent Childhood Experiences scale. Binge-eating disorder characteristics were assessed with the Questionnaire on Eating and Weight Patterns-5. Intuitive eating was assessed with the Intuitive Eating Scale-2. Associations of PCEs with binge-eating disorder characteristics and intuitive eating were examined using modified Poisson regressions and linear regressions. PCEs were cumulatively associated with binge-eating disorder characteristics and intuitive eating (p for trend <.05). College students in the low PCEs category (0-4 PCEs) had 1.37-1.92 times the prevalence of binge-eating disorder characteristics and had 3.89 points lower intuitive eating score than those in the high PCEs category (9-10 PCEs). Among the individual PCEs, intrapersonal PCE (i.e., feeling comfortable with oneself during childhood) was associated with both a lower prevalence of binge-eating disorder characteristics (aPR = 0.56-0.76) and a higher score of intuitive eating (adjusted ß = 1.87, 95% CI = 1.28-2.46) after adjustment for sociodemographic variables. Findings from this study suggest that PCEs may play a role in eating behaviors of college students. Future studies with nationally representative samples should prospectively examine associations of PCEs with binge-eating disorder characteristics and intuitive eating and explore the underlying mechanisms of the associations between PCEs and eating behaviors.

A complex relationship between intuitive eating and diet quality among university students.

Intuitive Eating (IE) theory posits eating in response to internal hunger, and satiety cues minimize impulses to over-consume foods. To assess this relationship, 758 university students (55% male) completed the Intuitive Eating Scale 2 (IES-2) and the Diet History Questionnaire II (DHQ). The IES-2 includes a total score and four subscale scores; unconditional permission to eat (UPE), reliance on hunger and satiety cues (RHSC), eating for physical rather than emotional reasons (EPR), and body food choice congruence (BFCC). Using multiple regression analysis, IE total was not related to diet quality. EPR (ß =0.10, p ≤ .01) and BFCC (ß =0.29, p ≤ .001) were positively related to diet quality. UPE (ß = -0.15, p ≤ .001) and RHSC (ß = -0.08, p ≤ .05) were negatively related to diet quality. This study found an antipodal relationship between the subscales of IE and diet quality among university students.

Exploratory Decision Trees to Predict Obesity Intervention Response among Hispanic American Youth.

Introduction: Individual variability in weight-related outcomes from obesity intervention is widely acknowledged, yet infrequently addressed. This study takes a first step to address individual variation by determining characteristics that distinguish responsive (improvements in BMI) from unresponsive individuals. Methods: Classification regression tree (CRT) analysis grouped 185 low-income, Hispanic American middle school students who received a school-based obesity intervention. Predictors included baseline age, gender, standardized BMI, health-related quality of life (PedsQL), minutes of moderate-vigorous physical activity (MVPA; accelerometry), energy consumption, and dietary quality (Block Kids 2004 Food Frequency Questionnaire). Response regarding weight-related outcomes to the intervention was defined according to the American Academy of Pediatrics (AAP) guidelines. Six trees were produced, one for 3- and one for 6-month outcomes among all participants, participants with healthy weight status, and participants with overweight/obesity at baseline. Results: The AAP criteria for response were met by 57.3% and 35.1% of participants at 3 and 6 months, respectively. CRT produced six unique trees. Notably, minutes of MVPA appeared twice (the first time at the top of the tree) in most 3-month models. In addition, response at 3 months consistently appeared as the first variable in all the 6-month models. Conclusions: Overall, the number of distinct pathways and the repeated appearance of the same variable within a pathway illustrate the complex, interactive nature of factors predicting an intervention response. Initially unresponsive individuals were unlikely to respond later in the intervention. More complex modeling is needed to better understand how to best predict who will be responsive to interventions.

Response to school-based interventions for overweight and obesity: A systematic scoping review.

Heterogeneity of response to paediatric obesity interventions is one of the greatest challenges to obesity care. While evaluating school-based interventions by mean changes compared to control is important, it does not provide an understanding of the individual variability in response to intervention. The objective of this study was to comprehensively review school-based interventions that reported study results in terms of response and identify definitions of response used. A scoping review was conducted using a systematic search of five scientific databases from 2009 to 2021. Inclusion criteria included randomized controlled trial design, school-based setting, weight-based outcomes (e.g., BMI, BMI z-score), weight-based outcomes analysed among youth with overweight/obesity, a study conducted in a developed country and publication in English. A total of 26 reports representing 25 unique studies were included. Overall, 19% (5/26) of articles reported response. Response was defined in three ways: maintenance/decrease in BMI z-score, decrease in BMI z-score ≥0.10, and decrease in BMI z-score ≥0.20. Few school-based interventions identified an a priori intervention goal or identified the proportion of participants who responded to the intervention. Without such evaluation participants who do not benefit are likely to be overlooked.

Incorporating Nutrition Counseling into Lifestyle Medicine.

Despite considerable evidence that plant-based diets can significantly improve health, medical professionals seldom discuss this with their patients. This issue might occur due to minimal training received in medical education, lack of time, and low self-efficacy for counseling patients about diet. Nutrition and lifestyle change should be considered a core competency for all physicians and health professionals looking for cost-effective ways to improve patient health outcomes and reduce nutrition-related chronic diseases. Strategies for health professionals to acquire nutrition counseling skills in medical training and clinical practices are discussed.

The Importance of Emotional Regulation in Mental Health.

Mental health is a critical component of overall well-being and exists on a continuum much like physical health. Although many ways to assess mental health exist outside of either having a disorder or not, practitioners often rely on the presence or absence of symptomatology. The assessment and promotion of emotional regulation in patients is one way to encourage individuals to engage in mental health-promoting behaviors. Specific techniques are discussed that address emotional regulation. Overall, providing patients with the tools to regulate emotional responding will likely have a direct impact on well-being as well as reduce MH symptomology.

Correlates of Early Prenatal Care Access among U.S. Women: Data from the Pregnancy Risk Assessment Monitoring System (PRAMS).

OBJECTIVES: Early first trimester prenatal counseling could reduce adverse maternal and child health outcomes. Existing literature does not identify the length of time between suspecting pregnancy and attending their first prenatal visit. Identifying this potential window for change is critical for clinical practice, intervention programming and policy change. METHODS: The study sample was composed of women in the United States who responded to the Pregnancy Risk Assessment Monitoring Systems survey in 2016, for the following questions-when they first suspected pregnancy, when they attended their first prenatal visit, were they able to receive prenatal care as early as they wished, and perceived barriers to receiving prenatal care. RESULTS: On average, participants became certain they were pregnant at 6.0 (SE = 0.1) weeks gestation, while participants reported having their first prenatal care visit at 9.3 (SE = 0.1) weeks, with clear health disparities by race, age, WIC participation, education level, and marital status. About 15% of women reported not receiving prenatal care as early as they wished. Structural or financial barriers in the health care system were common: 38.1% reported that no appointments available, 28.2% reported not having money or insurance to pay for the visit, 27.3% reported that the doctor or health plan would not start care, and 22.5% reported not having a Medicaid card. CONCLUSIONS FOR PRACTICE: This study illustrates a window for opportunity to provide earlier prenatal care, which would facilitate earlier implementation of prenatal counseling. Strategies to address barriers to care on the patient, provider and systemic levels, particularly among vulnerable population groups, are warranted. WHAT IS ALREADY KNOWN ON THIS SUBJECT?: Seeking prenatal care early is associated with better health outcomes for women and infants. A window of opportunity exists between suspecting pregnancy and attending a first prenatal visit. WHAT THIS STUDY ADDS?: Clear health disparities were apparent in both recognizing their pregnancies, and receiving early prenatal care by race, age, WIC participation, education level, and marital status. About 15% of women reported not receiving prenatal care as early as they wished, and many attributed this later care to structural or financial barriers in the health care system.

Harmonizing Ratings From Different School Environment Assessment Methods: A Simplified Approach.

BACKGROUND: This study describes a method for harmonizing data collected with different tools to compute a rating of compliance with national recommendations for school physical activity (PA) and nutrition environments. METHODS: We reviewed questionnaire items from 84 elementary schools that participated in the Childhood Obesity Research Demonstration (CORD) project, which was 3 distinct childhood obesity prevention projects in 7 communities in California, Massachusetts, and Texas. Each project used tools specific to its programs, schools, and communities. While this approach increased the feasibility of data collection, it created a challenge with the need to combine data across projects. We evaluated all questionnaire items and retained only those items that assessed one or more recommendations and constructed several items to indicate compliance or noncompliance with the respective associated recommendations. RESULTS: Ten constructed items covered 11 of the 20 recommendations. Analysis indicated that the scores detected variability in compliance both among communities and among school within communities. CONCLUSIONS: The scores captured differences in compliance with the national recommendations at multiple levels. Our method, designed for creating common scores, may be useful in integrated data analysis, systematic reviews, or future studies requiring harmonizing of data collected via different tools.

The ontology of fast food facts: conceptualization of nutritional fast food data for consumers and semantic web applications.

BACKGROUND: Fast food with its abundance and availability to consumers may have health consequences due to the high calorie intake which is a major contributor to life threatening diseases. Providing nutritional information has some impact on consumer decisions to self regulate and promote healthier diets, and thus, government regulations have mandated the publishing of nutritional content to assist consumers, including for fast food. However, fast food nutritional information is fragmented, and we realize a benefit to collate nutritional data to synthesize knowledge for individuals. METHODS: We developed the ontology of fast food facts as an opportunity to standardize knowledge of fast food and link nutritional data that could be analyzed and aggregated for the information needs of consumers and experts. The ontology is based on metadata from 21 fast food establishment nutritional resources and authored in OWL2 using Protégé. RESULTS: Three evaluators reviewed the logical structure of the ontology through natural language translation of the axioms. While there is majority agreement (76.1% pairwise agreement) of the veracity of the ontology, we identified 103 out of the 430 statements that were erroneous. We revised the ontology and publicably published the initial release of the ontology. The ontology has 413 classes, 21 object properties, 13 data properties, and 494 logical axioms. CONCLUSION: With the initial release of the ontology of fast food facts we discuss some future visions with the continued evolution of this knowledge base, and the challenges we plan to address, like the management and publication of voluminous amount of semantically linked fast food nutritional data.

A staged approach to address youth unresponsive to initial obesity intervention: a randomized clinical trial.

BACKGROUND/OBJECTIVE: Maintenance interventions inherently require BMI improvement to maintain. This overlooks individuals initially unresponsive to obesity interventions. Staged pediatric clinical treatment guidelines were adapted to the school setting to develop an escalated treatment option for individuals initially unresponsive. This staged randomized controlled trial examined differences between escalated treatment (Take CHARGE!) and a maintenance program (PE Planners). Take CHARGE was hypothesized to have greater improvements in BMI as a percentage of the 95th BMI Percentile (%BMIp95) than PE Planners. SUBJECTS/METHODS: From 2018 to 2020, 171 middle and high schoolers (BMI Percentile ≥ 85) were recruited from a Houston school district to participate in a staged obesity intervention in their physical education (PE) class. After receiving a semester-long intensive lifestyle intervention (ILI) with established efficacy, all participants were randomized to Take CHARGE (n = 85) or PE Planners (n = 86). Take CHARGE escalated the behavioral treatment of obesity received in ILI with more frequent individual sessions, additional opportunities for parental and school staff involvement, and increased mentorship from trained college students. PE Planners allowed participants to decide how they wanted to be active in PE class. Mixed linear modeling examined %BMIp95 overtime between groups. This trial was registered at ClinicalTrials.gov (#NCT04362280). RESULTS: Participants were 13.63 ± 1.32 years old; 59% were female, and 85% were Hispanic. Among those initially unresponsive to ILI, Take CHARGE had significantly greater decreases in %BMIp95 than PE Planners (ß = -0.01, p < 0.01). Conversely, among those initially responsive, Take CHARGE had significantly smaller decreases in %BMIp95 than PE Planners (ß = 0.02, p < 0.05). Intention-to-treat analysis had similar results. CONCLUSIONS: Participant outcomes in semester two differed based on initial response. Individuals responsive to initial intervention were most likely to benefit from a maintenance intervention and those initially unresponsive benefited more from escalated treatment. This indicates the need for staged intervention protocols to better address obesity in the school setting.

Feasibility and Efficacy of the "FUNPALs Playgroup" Intervention to Improve Toddler Dietary and Activity Behaviors: A Pilot Randomized Controlled Trial.

This study evaluated the feasibility and effects of the Families Understanding Nutrition and Physically Active Lifestyles (FUNPALs) Playgroup on toddler (12-36-month-old) diet and activity behaviors. Parent-toddler dyads were recruited from disadvantaged communities and randomly assigned to receive 10-weekly sessions of the FUNPALs Playgroup (n = 24) or dose-matched health education control group (n = 26). FUNPALs Playgroups involved physical and snack activities, delivery of health information, and positive parenting coaching. The control group involved group health education for parents only. Process outcomes (e.g., retention rate, fidelity) and focus groups determined feasibility and perceived effects. To evaluate preliminary effects, validated measures of toddler diet (food frequency questionnaire and a carotenoid biomarker), physical activity (PA; accelerometers), general and feeding parenting (self-report surveys), and home environment (phone interview) were collected pre and post. The sample comprised parents (84% female) who self-identified as Hispanic/Latino (38%) and/or African American (32%). Retention was high (78%). Parents from both groups enjoyed the program and perceived improvements in their children's health behaviors. Objective measures demonstrated improvement with large effects (η2 = 0.29) in toddler diet (p < 0.001) but not PA (p = 0.099). In conclusion, the FUNPALs Playgroup is feasible and may improve toddler eating behaviors.

Exploring qualities of ethnically diverse parents related to the healthy home environment of toddlers.

Parents serve as role models and household policy makers for their children's home social environment. Also, parents may influence the home physical environment through the provision of resources to support their children's dietary, activity, and sleep behaviors. Understanding the parental characteristics related to children's home environment may allow for tailoring obesity interventions to families' needs. This study aimed to explore parental qualities (general parenting styles, parent feeding practices, and parental BMI) related to healthy home food, physical activity, media and sleep environment of toddlers. A total of 50 multi-ethnic parents with toddler age children who were enrolled in a randomized pilot study of a wellness program completed the Structure and Control in Parent Feeding (SCPF) questionnaire and Comprehensive General Parenting Questionnaire (CGPQ). Parental BMI was calculated using self-reported weight and height data. The Healthy Home Survey, the Home Food Inventory, the Sleep Environment Questionnaire, and items developed for this study were standardized and summed to create home food, physical activity, screen media, and sleep environment scores; high scores reflected healthier environments. To examine the relationships between parental qualities and the home environment, Pearson's correlation test was performed. Parental BMI and overall healthy home environment were inversely associated (r = -0.306; p = 0.032). Structure in general parenting and parental feeding practice were positively correlated with the overall healthy home environment (r = 0.336; p = 0.026) and healthy home food environment (r = 0.415; p = 0.003), respectively. The coercive control general parenting was inversely related to overall healthy home environment score (r = -0.333; p = 0.022). Based on the findings from this study, parents who provide clear communication, set consistent rules, avoid pressure to control their child's behavior, and have lower BMI tend to live in a home environment that support children's health behaviors.

The Importance of Health Values Among Health Care Providers.

Medical professionals' healthy eating and physical activity behaviors are likely to wane as other life events and everyday pressures increase. This is vital because as health behaviors decrease, the likelihood that this topic is addressed with patients also decreases. Increased training to improve health care providers' knowledge about lifestyle behaviors may be inadequate to actually bring about a healthier lifestyle. The area of personal identity and value formation may shed light on a significant barrier in this area. Developing health care professionals who have values consistent with a healthy diet and physical activity, instead of just being informed about it, would increase the likelihood that healthy behavior changes are discussed with patients. Strategies to encourage value formation around healthy lifestyles among medical professionals are discussed.

Randomized Controlled Trial to Increase Physical Activity Among Hispanic-American Middle School Students.

BACKGROUND: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also examined. METHODS: Hispanic-American middle school students (N = 193) were recruited from a school district in Houston, Texas. Participants were randomized to either a circuit-based physical activity intervention or TAU (PE class as usual). MVPA was assessed using accelerometry at baseline and 6 months. Repeated measures ANCOVA were conducted to examine changes in MVPA, overall and stratified by sex and weight classification. This procedure was repeated for zBMI. RESULTS: Participants were 12.10 ± 0.63 years old and 53% were girls. Overall those in intervention increased weekday MVPA more than TAU (F(1,190) = 7.03, p < .01). Intervention girls increased weekday MVPA; whereas TAU girls decreased weekday MVPA (F(1,99) = 7.36, p < .01). Among those with obesity, there was no difference in MVPA between conditions (F(1, 56) = 0.33, p = .57), but Intervention decreased zBMI significantly more than TAU (F(1, 56) = 6.16, p < .05). CONCLUSIONS: Structured PE classes grounded in behavioral theory may be an important strategy to prevent typical decreases in MVPA during adolescence, particularly among girls and for youth with obesity.

The association between pre-conception intuitive eating and gestational weight gain.

PURPOSE: To determine if pre-conception intuitive eating, an adaptive eating behavior, was related to gestational weight gain (GWG) and the likelihood of exceeding GWG recommendations. METHODS: This prospective survey study took place in an outpatient obstetric clinic. Participants completed the pre-conception Intuitive Eating Scale for Pregnancy during a prenatal check-up appointment and total GWG was collected from the medical record. The pre-conception Intuitive Eating Scale for Pregnancy assesses unconditional permission to eat, eating for physical rather than emotional reasons, and reliance on hunger and satiety to inform what, when, and how much to eat. Hierarchical linear multiple regression and logistic multiple regression analyses determined associations between pre-conception intuitive eating and GWG on the total sample and stratified by weight status (normal/underweight, overweight, and obese). RESULTS: The majority of the sample (n = 253) was white, married, employed, had annual household income > $50,000, and had a college degree. No aspects of pre-conception intuitive eating predicted the likelihood of excess GWG. However, in the total sample, unconditional permission to eat (subscale) was inversely related to total GWG (B = -0.16, p < 0.05). Among women with obesity (n = 36), eating for physical rather than emotional reasons (subscale) was inversely related to total GWG (B = -0.47, p < 0.05). DISCUSSION: Some aspects of intuitive eating during the pre-conception period were related to total GWG, particularly for women with obesity. However, intuitive eating scores did not increase or decrease the likelihood of excess GWG. More research is needed to understand the mechanisms for this association before clinical recommendations can be made. LEVEL OF EVIDENCE: Level III (Evidence obtained from well-designed cohort or case-control analytic studies).
