Abstract	Background: The high frequency of eating disorders (EDs) in sports speaks of a need for early-stage preventive measures. Objectives: This study evaluated the acceptability of an age, sex, and sports adapted version of the "Body Project" and changes in mental health symptoms. Methods: This noncontrolled pilot study included a class of athletes from 18 sports (N = 73, 13-14 years) at a sport-specialized junior high school in six small-group workshops. We interviewed 34 athletes on program acceptability, and all athletes responded to questionnaires at pretest, posttest, and 6-month follow-up including the Body Appreciation Scale 2-Children, Social Attitudes towards Appearance Questionnaire-4 revised, Eating Disorder Examination Questionnaire Short form-12 modified, and questions about body appearance pressure (BAP). Results: Athletes found the program acceptable and beneficial, but some missed physically oriented activities or did not identify with the focus, particularly boys. There were acceptable levels in mental health constructs before the workshops. There were temporary changes in the percentage of boys experiencing "BAP in society" by -14.8% points (95% CI: -.6 to .0, p = .04), % in total group experiencing "BAP at school" by +11% points (95% CI: .0-.2, p = .05), thinness idealization by girls (g = .6, p = .002) and total group (g = .4, p = .006), and muscularity idealization by boys (g = .3, p = .05) and total group (g = .23, p = .04). Discussion: Athletes experienced benefits from the Young Athlete Body Project. Seeing stabilization in outcomes may mean a dampening of the otherwise expected worsening in body appreciation and ED symptoms over time. Public significance: Adolescent athletes are at risk for developing EDs. Due to lack of prevention programs for this group, we adapted and evaluated a well-documented effective program, the Body Project, to fit male and female athletes <15 years. The athletes accepted the program and experienced participation benefits, with stronger acceptance among girls. Our promising findings encourage larger scaled randomized controlled trials to further evaluate a refined version this program among very young athletes.

Abstract	Background: Use of dietary supplements (DS) and muscle enhancing dietary supplements (MEDS) is frequent among students despite the lack of evidence of effects and health risks related to consumption. We need to increase our understanding of students' motivation, examine potential gender differences, and explore explanatory factors, to address preventive measures related to use. Therefore, this study aimed to explore the frequency of, and the reasons for, DS use among university students, as well as explanatory factors for use of MEDS. Method: Male and female students from nine Norwegian universities participated in this cross-sectional study. Participants responded to questions about demographics, DS and MEDS use, internalization of body ideals, physical activity- and exercise level, motives for exercise, and exercise context. Independent t-test, Chi-square test, Pearson's correlation, and logistic regression were used to investigate between group differences, associations, and explanatory factors for use, respectively. P-values ≤ 0.05 were defined as significant. Results: A total of 1001 males (34%) and females, with a mean(sd) age of 24.21(4.76) years, participated. The frequency of DS use was 42% and 40% (p = .414) in males and females, respectively, in which more males than females used DS to improve physical or mental performance (p = < .001), increase muscle mass (p = < .001) and weight for health (p = .014), and improve appearance (p = < .001). In males and females, respectively, 25% and 10% used MEDS (p = < .001). In males, being a fitness center member (OR:3.80), exercising to improve muscle mass (OR:1.96), and a higher physical activity level (OR:1.09) positively explained MEDS use, while exercising to increase endurance (OR:0.49) and being an exercise science student (OR:0.47) negatively explained MEDS use. In females, internalizing the athletic body ideal (OR:1.78) and exercising to improve muscle mass (OR:1.74) positively explained MEDS use. Conclusions: Our main findings indicate that a surprisingly high percentage of male and female Norwegian students use DS and MEDS, and that reasons for use, and variables explaining the variability in frequency of use, differ between genders. Longitudinal studies to investigate direction of associations are needed in future research.

Abstract	Purpose: Integrating digital technologies into sexual health education can offer advantages for connecting with adolescents, particularly populations who may be underserved through common school-based approaches. This study assessed the effectiveness of In the Know, an in-person, group-based sexual health education program integrating digital technologies, codesigned with adolescents. Methods: The study design was a cluster randomized trial with 1,263 adolescents aged 13-19 in 95 cohorts, implemented in community-based organizations and schools throughout Fresno County, California. Participants completed a baseline survey and a follow-up survey 3 months later. Two-level mixed-effects regression models with random intercepts for cohort were used to estimate the intervention's impact on unprotected sex, use of clinical health services, knowledge of local sexual health services, technology use to find or schedule services, and sexual health knowledge at the 3-month follow-up. Results: The average age of participants was 15.7 years, and the majority identified as Hispanic (71%). In adjusted analyses, intervention group participants were more likely to use clinical services (42.7% vs. 33.2%, p = .009) and reported greater sexual health knowledge at 3 months (57.6% of items answered correctly vs. 50.7%, p = .001). No significant differences were observed in the other outcomes by study group. Discussion: In the Know participants demonstrated greater use of clinical health services and sexual health knowledge at 3 months. The study findings show the potential for incorporating user-centered design and technology into sexual health education to better support adolescents who may have limited access to this important information.

Abstract	Introduction: Maternal adverse childhood experiences have been linked to a variety of negative health outcomes in young children; however, young adults and, specifically, young adult Latinos have been vastly understudied. This study investigates the intergenerational pathway between maternal adverse childhood experiences and behavioral health outcomes of their young adult children, as mediated through young adults' own adverse childhood experiences and maternal depression. Methods: Structural equation modeling was used to analyze data (in 2023) from mothers and their young adult children (n=398 dyads) enrolled in the Center for the Health Assessment of Mothers and Children of Salinas cohort, a primarily Latino agricultural sample. Maternal and young adult adverse childhood experiences were self-reported retrospectively during a visit at the age of 18 years (2018-2020). Young adult- and maternal-reported internalizing and maternal-reported externalizing behaviors were assessed at the age of 18 years with the Behavior Assessment for Children, second edition. Maternal depression was assessed during a visit at the age of 9 years (2010-2012) using the Center for Epidemiologic Studies Depression Scale. Results: Maternal and young adult adverse childhood experiences were weakly but statistically significantly correlated (r=0.22). Maternal adverse childhood experiences were statistically significantly associated with maternal-reported youth internalizing symptoms (β=0.29; 95% CI=0.19, 0.38; p<0.001) and externalizing symptoms (β=0.24; 95% CI=0.14, 0.33; p<0.001) and marginally associated with youth-reported internalizing symptoms (β=0.08; 95% CI= -0.02, 0.18; p=0.13). Youth adverse childhood experiences and maternal depressive symptomatology mediated the associations between maternal adverse childhood experiences and young adult outcomes. Conclusions: Findings demonstrate the potential impacts of adversity across generations in Latino immigrant families, an understudied population. Understanding the mechanisms and factors associated with these pathways may lead to strategies that prevent poor mental health outcomes in young adults.

Abstract	Acquiring age-appropriate social skills, arguably a major prerequisite for favorable psychosocial development in children, is targeted in a range of interventions. Hence, identifying factors that limit this acquisition may inform preventative and treatment efforts. Personality disorders are characterized by pervasive and enduring dysfunctional interpersonal functioning, including parenting, and could thus entail risk for offspring in not developing adaptive interpersonal skills. However, no study has tested this possibility. A representative sample drawn from two birth cohorts of Norwegian 4-year-olds (n = 956) and their parents was followed up at ages 6, 8, and 10 years. Parents' personality disorder symptoms were measured dimensionally with the DSM-IV and ICD-10 Personality Questionnaire, and children's social skills were evaluated by the Social Skills Rating System. A difference-in-difference approach was applied to adjust for all unmeasured time-invariant confounders, and parental symptoms of depression and anxiety were entered as covariates. Increased Cluster B symptoms in parents of children aged 4 to 6 years predicted decreased social skill development in offspring (B = -0.97, 95% CI -1.58, -0.37, p = 0.002). On a more granular level, increased symptoms of borderline (B = -0.39, CI -0.65, -0.12, p = 0.004), histrionic (B = -0.55, CI -0.99, -0.11, p = 0.018), and avoidant (B = -0.46, CI-0.79, -0.13, p = 0.006) personality disorders in parents predicted decreased social skill development in offspring. Subclinical levels of borderline, histrionic and avoidant personality disorders in parents may impair the development of social skills in offspring. Successfully treating these personality problems or considering them when providing services to children may facilitate children's acquisition of social skills.

Abstract	Background: Little is known about longer-term adherence to recommended physical activity (PA) and dietary behaviors after metabolic and bariatric surgery (MBS) and whether adherence is associated with weight recurrence. Objectives: To explore (1) changes in and associations between adherence to PA and general dietary recommendations after MBS and (2) whether PA and dietary behaviors interact to predict weight recurrence. Setting: University hospital; public practice. Methods: Participants completed ActiGraph PA monitoring, dietary questionnaire, and weighing 1 and 5 years after surgery. Parametric and non-parametric tests evaluated changes in and associations between adherence to PA and dietary recommendations. Multiple linear regression explored associations of adherence and weight recurrence 5 years post-surgery. Results: A total of 73 participants (66% loss to follow-up, 80.8% females) were included. From 1 to 5 years after surgery, adherence to PA recommendations did not change (23.5% versus 20.5%, P = .824), whereas adherence to dietary recommendations decreased (P = <.001). Adherence to PA recommendations is positively associated with eating fruits and vegetables and limiting intake of sugar and fat at 1 year (P < .05) and negatively associated with choosing meat with less fat at 5 years (P = .018). Adherence to PA and dietary behaviors did not independently contribute or interact to predict weight recurrence. Conclusions: Adherence to recommendations was poor. Dietary adherence decreased from 1 to 5 years post-surgery, whereas PA adherence remained stable. PA adherence was positively associated with adherence to some dietary recommendations at 1 year but not at 5 years. Neither behavioral adherences were associated with weight recurrence. Additional research is needed to understand how to improve adherence and its relationship with other health outcomes after MBS.

Book ; Online: Statistical model concept to quantify input and output of water, nitrogen and phosphorus for lakes with partly gauged watersheds

Sørensen, Peter Borgen / Nielsen, Anders

2023

P that enters a lake will determine the ecological state of the lake, and the mass release ... P is an integral of several pathways, each having different contributions to the total mass load ...

Abstract	Valid mass load predictions of nutrients, in particular nitrogen (N) and phosphorus (P), are needed for the limnological understanding of single lake ecosystems as well as larger river/lake ecosystems. The mass of N and P that enters a lake will determine the ecological state of the lake, and the mass release from the lake will determine the ecological state of downstream ecosystems. Hence, establishing sound quantifications of the external load is crucial and e.g. contributes to the foundation of assessments of necessary management interventions to improve or preserve the ecological integrity of lakes. The external load of N and P is an integral of several pathways, each having different contributions to the total mass load. Around the world, balances of N and P have been derived for decades to support both lake water quality monitoring and research, but it can be difficult and, thus, costly to make detailed and sufficiently covering measurement campaigns in all tributaries (surface as well as groundwater) in the watershed of the N and P load including seasonality and temporal change from year to year. Thus, load prediction is facing challenge of uncertainty due to unmeasured loads, which can be a consequence of limited resources available for the water flow recordings and water concentration measurements in inlets around the lake, or simply due to invisible water flow taking place through the lake bottom. The lake outlet will typically take place in one single river, so the outlet recording seems easier to measure than inlets, however, the outlet may also have unmeasured parts in cases where water is leaching out though the lake bottom. In this paper, we propose a method that applies incomplete data sets (incomplete in the sense of temporal frequency and percentage of gauged watershed) to generate time series that predict the N and P loads entering and leaving the lake.
