A Pilot Study: Do Children Who Run Marathons Have More Osteoarthritis in the Lower Extremities as Adults
Objective: To compare self-reported osteoarthritis of the knee and hip in adults who ran at least 1 marathon as a child with adults who ran high-school cross country (HSCC). Design: Subject self-recall retrospective survey. Setting: Electronic survey. Participants: 319 adults who either ran a marathon under age 18 or ran HSCC recruited from running clubs, marathon participants, and on-line interest groups. Interventions: Survey. Main Outcome Measures: Self-reported history of osteoarthritis (OA), joint pain, anterior cruciate ligament injury, still running or running marathons, and number of marathons as an adult. Results: One hundred twenty-three respondents ran a marathon under age 18 (26% female) and were 40 years old (sd 16) and 196 ran HSCC (53% female) and were 36 years old (sd 13). The mean age of first marathon was 15 (sd 2.3, range 5-17); 50% ran 1% and 50% ran >1 marathon. Child marathoners reported a family history of OA in knees or hips (26%) or a joint replacement (30%) compared with 24% and 28% of HSCC runners. 10% of child marathoners and 7% of HSCC reported OA and 24% and 21% reported daily or weekly joint pain. 91% of all respondents are still running; 78% of child marathoners (mean 17, range 1-91) and 80% HSCC ran ≥1 marathons as adults (mean 10, range 1-80). Conclusions: Adults who ran marathons as children compared with adults who ran HSCC self-report similar rates of the knee and hip OA, chose to participate of their own accord, continue to run as adults, played other sports, and did not “specialize” in marathons.

Assessing compulsive sexual behavior disorder: The development and international validation of the compulsive sexual behavior disorder-diagnostic inventory (CSBD-DI)
Background and aims: The World Health Organization's International Classification of Diseases (ICD-11) includes Compulsive Sexual Behavior Disorder (CSBD), a new diagnosis that is both controversial and groundbreaking, as it is the first diagnosis to codify a disorder related to excessive, compulsive, and out-of-control sexual behavior. The inclusion of this novel diagnosis demonstrates a clear need for valid assessments of this disorder that may be quickly administered in both clinical and research settings.Design: The present work details the development of the Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI) across seven samples, four languages, and five countries.Setting: In the first study, data were collected in community samples drawn from Malaysia (N = 375), the U.S. (N = 877), Hungary (N = 7,279), and Germany (N = 449). In the second study, data were collected from nationally representative samples in the U.S. (N = 1,601), Poland (N = 1,036), and Hungary (N = 473).Findings: Across both studies and all samples, results revealed strong psychometric qualities for the 7-item CSBD-DI, demonstrating evidence of validity via correlations with key behavioral indicators and longer measures of compulsive sexual behavior. Analyses from nationally representative samples revealed residual metric invariance across languages, scalar invariance across gender, strong evidence of validity, and utility in classifying individuals who self-identified as having problematic and excessive sexual behavior, as evidenced by ROC analyses revealing suitable cutoffs for a screening instrument.Conclusion: Collectively, these findings demonstrate the cross-cultural utility of the CSBD-DI as a novel measure for CSBD and provide a brief, easily administrable instrument for screening for this novel disorder.

Exploring Coping Strategies and Social Support among Individuals with Compulsive Sexual Behavior Concerns: Results from a Clinical Sample
Compulsive sexual behavior (CSB) is associated with poor affect regulation and difficulties in interpersonal relationships. People experiencing CSB may engage in ineffective coping and have poor social support. The current study tested relationships between several coping orientations and sources of perceived social support (from significant others, friends, and family) among men seeking treatment for CSB and other sexual health and relationship concerns. Results indicated that religion and self-blame coping orientations predicted greater CSB concerns. Social support from friends and coping with humor were associated with lower CSB. These findings identify potential areas of intervention to target CSB-related concerns.

The Relationship between Compulsive Sexual Behavior, Religiosity, and Moral Disapproval
Compulsive sexual behavior (CSB) is associated with religiosity and moral disapproval for sexual behaviors, and religiosity and moral disapproval are often used interchangeably in understanding moral incongruence. The present study expands prior research by examining relationships between several religious orientations and CSB and testing how moral disapproval contributes to these relationships via mediation analysis. Results indicated that religious orientations reflecting commitment to beliefs and rigidity in adhering to beliefs predicted greater CSB. Additionally, moral disapproval mediated relationships between several religiosity orientations and CSB. Overall, findings suggest that religiosity and moral disapproval are related constructs that aid in understanding CSB presentations.

Reliability and Factor Structure of the Sex Offender Treatment Intervention and Progress Scale
Assessment of risk of sexual recidivism has progressed from tools containing only static factors to tools including dynamic (i.e., changeable) risk factors. The psychometric properties and factor structure of one such scale, the Sex Offender Treatment Intervention and Progress Scale (SOTIPS) were explored. Seven hundred and thirty-one men assigned probation for sexual crimes in New York City and Maricopa County, Arizona were administered SOTIPS three times: intake into probation, six months later, and six months after that. SOTIPS showed good internal consistency (Time 1 ω = .87, Time 2 ω = .89, and Time 3 ω = .91), and acceptable inter-rater reliability (for the 26 cases rated in the same month, ICC =.821). An exploratory factor analysis did not result in the original factor structure proposed by the developers; instead, SOTIPS showed two factors: sexual risk and antisocial opposition. This factor structure required the averaging of two items to avoid collinearity. SOTIPS showed temporal invariance indicating that its factor structure and its association to underlying latent variables are consistent over time.

Kitchen Adequacy and Child Diet Quality in a Racially/Ethnically Diverse Sample
This study examined kitchen adequacy in a racially/ethnically diverse low-income sample and associations with child diet quality. Families with children age five to seven years old (n = 150) from non-Hispanic white, non-Hispanic Black, Hispanic, Native American, Hmong, and Somali families were recruited through primary care clinics. More than 85% of families had 15 of the 20 kitchen items queried, indicating that the sample had adequate kitchen facilities. Only one item (a kitchen table) was associated with higher overall diet quality of children. In contrast, children living in households with can openers and measuring spoons consumed more sodium and added sugars, respectively.

Days Needed to Characterize the Healthfulness of a Typical Dinner Meal in Direct Observational Research: Mixed Methods Study
Background: Prior research around the home meal environment has demonstrated that family meals are associated with positive health outcomes for children and adolescents. Researchers have begun using direct observational methods to understand key aspects of family meals such as meal healthfulness and family meal frequency to explain the protective nature of family meals. Direct observational research, however, can be resource intensive and also burdensome for participants. Information about the number of days needed to sufficiently characterize typical meal healthfulness using direct observational research methods is needed. Objective: The current study aimed to produce guidance about the number of meals necessary to approximate typical meal healthfulness at the family dinner meal occasion in a direct observational, mixed methods study of the home food environment. Methods: Families were recruited between 2012-2013 from primary care clinics in the Minneapolis-St Paul metropolitan area (N=120). A total of 800 meals were collected as part of the Family Meals LIVE! mixed methods study. The Healthfulness of Meal Index was used to evaluate meal dietary healthfulness of foods served at 8 family meal occasions. Participating families were provided an iPad (Apple Inc) and asked to video-record 8 consecutive days of family dinner meals with a minimum of two weekend meals. After the meal, families completed a meal screener, which is a self-reported, open-ended measure of the foods served at the meal. Results: Weekend and weekday meals differed in their measurement of meal healthfulness, indicating that at least one weekday and one weekend day are necessary to approximate meal healthfulness. Single-day measurement mischaracterized the strength of the relationship between the quality of what was served and intake by almost 50%, and 3 to 4 observation days were sufficient to characterize typical weekly meal healthfulness (r=0.94; P<.001). Conclusions: Relatively few direct observational days of family meals data appear to be needed to approximate the healthfulness of meals across 1 week. Specifically, 1 weekday and 1 weekend observation are needed, including a total of 3 to 4 days of direct observational meal data. These findings may inform future direct observational study designs to reduce both research costs and participant burden in assessing features of the meal environment.

Tinea Gladiatorum Prevalence Among Wrestlers in the Era of Required Skin Inspection
: Transmittable skin infections in sport are a concern, especially for wrestlers. Current methods for limiting tinea gladiatorum transmission in United States high school wrestling include a required skin inspection protocol. Tinea prevalence before and after the skin inspection protocol was instituted is not widely known. We prospectively determined tinea prevalence among a Minnesota high school wrestler cohort over their 12-week season and compared this to point-in-time incidences reported in wrestlers not subject to a skin inspection protocol. Wrestlers having a suspicious rash at the skin inspection (raised, red, > 5 mm diameter, and with dry flaky scale) were recruited. Among suspicious rashes, tinea gladiatorum infection was determined using direct microscopy with chlorazol black staining. Thirty-eight of 510 wrestlers (7%) developed a rash suspicious for tinea. Thirty-four wrestlers that had rash(s) were enrolled and their rash was tested. Twenty-two of 510 wrestlers developed tinea gladiatorum throughout the season. Tinea gladiatorum prevalence was 4.3% (95% CI 2.5-6.1%). Four wrestlers with rash were not available for testing (unable to obtain timely consent (two) or obtain adequate sample(two)). Prevalence was less than suggested by the incidences previously reported in wrestling populations.
