RESUMEN

BACKGROUND: The purpose of this study is to describe and assess a remote height and weight protocol that was developed for an ongoing trial conducted during the SARS COV-2 pandemic. METHODS: Thirty-eight rural families (children 8.3 ± 0.7 years; 68% female; and caregivers 38.2 ± 6.1 years) were provided detailed instructions on how to measure height and weight. Families obtained measures via remote data collection (caregiver weight, child height and weight) and also by trained staff. Differences between data collection methods were examined. RESULTS: Per absolute mean difference analyses, slightly larger differences were found for child weight (0.21 ± 0.21 kg), child height (1.53 ± 1.29 cm), and caregiver weight (0.48 ± 0.42 kg) between school and home measurements. Both analyses indicate differences had only minor impact on child BMI percentile (- 0.12, 0.68) and parent BMI (0.05, 0.13). Intraclass coefficients ranged from 0.98 to 1.00 indicating that almost all of the variance was due to between person differences and not measurement differences within a person. CONCLUSION: Results suggest that remote height and weight collection is feasible for caregivers and children and that there are minimal differences in the various measurement methods studied here when assessing group differences. These differences did not have clinically meaningful impacts on BMI. This is promising for the use of remote height and weight measurement in clinical trials, especially for hard-to reach-populations. TRIAL REGISTRATION: Clinical.

RESUMEN

Individuals with a premutation of the fragile X mental retardation (FMR1) gene are at risk for a variety of psychological, physical, and cognitive issues, including difficulty with word retrieval. The present study examined three indicators of word retrieval difficulty; reduced productivity, reduced lexical diversity, and increased errors in word retrieval in a group of 38 female premutation carriers during standard-length speech samples collected over a period of eight years. Our results revealed that as women aged, they produced fewer words, produced fewer different words, and had greater word retrieval errors. In addition, the rate of word retrieval errors was highly correlated between two speaking contexts, indicating that this difficulty was pervasive and not solely the result of speaking in monologue. Our results suggest that subtle areas of cognitive decline emerge at a much earlier age among female premutation carriers than would be expected during healthy aging.

RESUMEN

INTRODUCTION: Greater use of appearance-focused social media, such as Instagram, is associated with increased body dissatisfaction and eating disorder (ED) symptoms; however, questions remain about the mechanism connecting social media use to disordered-eating behaviors (DEBs). The proposed study evaluates how and for whom exposure to fitspiration or thinspiration on Instagram is associated with DEBs. METHODS: We will evaluate a hypothesized pathway from Instagram use to disordered-eating mediated by negative affect. We will test how individual differences in internalized weight stigma, trait self-esteem, and trait self-comparison moderate the pathway from social media use to negative affect. We will recruit 175 undergraduate women who report engaging in DEBs on average at least once per week over the past 3 months. Participants will complete a 7-day ecological momentary assessment protocol, during which they will report their Instagram use, affect, and engagement in DEBs. RESULTS: Multi-level modeling will be used to assess moderated mediation. Results from this study will provide increased specificity about how Instagram usage is linked to eating pathology and who may be most vulnerable to experiencing distress. DISCUSSION: Information about negative affect from Instagram and engagement in DEBs could contribute to the development of Just-In-Time Interventions for problematic social media use.

RESUMEN

INTRODUCTION: Expert opinion suggests that efforts to address childhood obesity should seek to transform the environments in which children operate. The objective of this study was to describe the extent to which multisetting programs and policies interact with community and child predictors and are associated with child body mass index (BMI) in the 130 US communities participating in the Healthy Communities Study. METHODS: For 2 years beginning in fall 2013, we collected data through key informant interviews on community programs and policies related to healthy weight among children that occurred in the 10 years before the interview. We characterized community programs and policies by intensity of efforts and the number of settings in which a program or policy was implemented. Child height and weight were measured during household data collection. We used multilevel modeling to examine associations of community programs and policies in multiple settings and child and community predictors with BMI z scores of children. RESULTS: The mean number of settings in which community policies and programs were implemented was 7.3 per community. Of 130 communities, 31 (23.8%) implemented community programs and policies in multiple settings. Higher-intensity community programs and policies were associated with lower BMI in communities that used multiple settings but not in communities that implemented programs and policies in few settings. CONCLUSION: Efforts to prevent childhood obesity may be more effective when community programs and policies are both intensive and are implemented in multiple settings in which children live, learn, and play.

RESUMEN

Individuals with fragile X syndrome (FXS) and their parents have a range of experiences navigating the crucial transition period between adolescence and adulthood. Semistructured interviews of 47 mothers of adolescents with FXS (mean child age = 15.89 years) were analyzed to identify mothers' changing expectations during the adolescent period and parent goals related to work and postsecondary education. Mothers' work and education goals were explored in relation to child factors such as language skills and autism characteristics. Lower language skills were associated with lower likelihood of reporting vocational goals. Results suggest that adolescents with FXS with lower language ability are less likely to have vocational plans for adulthood during this critical period and may need greater transition planning assistance.

RESUMEN

OBJECTIVES: We assessed the association between minority stress, mental health, and potential ameliorating factors in a large, community-based, geographically diverse sample of the US transgender population. METHODS: In 2003, we recruited through the Internet a sample of 1093 male-to-female and female-to-male transgender persons, stratified by gender. Participants completed an online survey that included standardized measures of mental health. Guided by the minority stress model, we evaluated associations between stigma and mental health and tested whether indicators of resilience (family support, peer support, identity pride) moderated these associations. RESULTS: Respondents had a high prevalence of clinical depression (44.1%), anxiety (33.2%), and somatization (27.5%). Social stigma was positively associated with psychological distress. Peer support (from other transgender people) moderated this relationship. We found few differences by gender identity. CONCLUSIONS: Our findings support the minority stress model. Prevention needs to confront social structures, norms, and attitudes that produce minority stress for gender-variant people; enhance peer support; and improve access to mental health and social services that affirm transgender identity and promote resilience.

RESUMEN

Alarmingly high HIV prevalence rates among African American men who have sex with men (AAMSM) require the development of effective prevention interventions. In this study of AAMSM conducted in two cities, we explored similarities and differences between HIV-positive and HIV-negative AAMSM on sociodemographic variables, HIV-related risk behaviors, and attitudinal constructs. Differences emerged in several major life areas: (1) poverty, employment, and use of mental health services, (2) sexual risk behaviors, and (3) self-identification with gay identity and culture. With regard to sociodemographic indicators, HIV-positive AAMSM were doing worse than HIV-negative AAMSM in that they were more likely to be disabled, to be living below the poverty level, and accessing mental health services. With regard to risk behaviors and partner characteristics, HIV-positive AAMSM were acting more responsibly than their HIV-negative counterparts, as they were more likely to have used a condom the last time they had sex. In addition, when compared to their HIV-negative counterparts, HIV-positive AAMSM were more likely to have either no casual partners at all or main or casual partners who were HIV-positive, thus preventing new HIV transmission by partnering with other HIV-positive men. Attitudinally, HIV-positive men were more accepting of their sexual attractions to men and were more likely to identify as gay than their HIV-negative peers. Although causality cannot be determined, the findings of this study can be used to strengthen HIV prevention efforts by improving the selection of targeted behaviors and prevention messages for HIV-positive and HIV-negative AAMSM.

RESUMEN

Introduction: The purpose of this study is to evaluate two recruitment strategies on schools and participant participation rates and representativeness (reach) within a pediatric obesity treatment trial tailored for families who live in rural areas. Methods: Recruitment of schools was evaluated based on their progress toward enrolling participants. Recruitment and reach of participants were evaluated using (1) participation rates and (2) representativeness of demographics and weight status of participants compared to eligible participants (who did not consent and enroll) and all students (regardless of eligibility). School recruitment, as well as participant recruitment and reach, were evaluated across recruitment methods comparing opt-in (i.e., caregivers agreed to allow their child to be screened for eligibility) vs. screen-first (i.e., all children screened for eligibility). Results: Of the 395 schools contacted, 34 schools (8.6%) expressed initial interest; of these, 27 (79%) proceeded to recruit participants, and 18 (53%) ultimately participated in the program. Of schools who initiated recruitment, 75% of schools using the opt-in method and 60% of schools using the screen-first method continued participation and were able to recruit a sufficient number of participants. The average participation rate (number of enrolled individuals divided by those who were eligible) from all 18 schools was 21.6%. This percentage was higher in schools using the screen-first method (average of 29.7%) compared to schools using the opt-in method (13.5%). Study participants were representative of the student population based on sex (female), race (White), and eligibility for free and reduced-price lunch. Study participants had higher body mass index (BMI) metrics (BMI, BMIz, and BMI%) than eligible non-participants. Conclusions: Schools using the opt-in recruitment were more likely to enroll at least 5 families and administer the intervention. However, the participation rate was higher in screen-first schools. The overall study sample was representative of the school demographics.

RESUMEN

Purpose: We describe the development of a measure of internalized transphobia, defined as discomfort with one's transgender identity as a result of internalizing society's normative gender expectations. Methods: An item pool was created based on responses from a small clinical sample (N = 12) to an open-ended questionnaire. Expert judges reviewed the items, resulting in a 60-item instrument for empirical testing. We conducted exploratory factor analysis (EFA) by using a community sample of 430 transgender individuals (aged 18-72, mean [M] = 37.4, standard deviation [SD] = 12.0), and confirmatory factor analysis (CFA) by using an online sample of 903 transgender individuals (aged 18-66, M = 31.6, SD = 11.1). Construct validity was examined by using correlations with instruments assessing related constructs administered to the online sample. Results: EFA resulted in a 52-item instrument with four subscales: Pride, Passing, Alienation, and Shame. CFA, after removal of half of the items, retained the four-factor structure. The final 26-item scale showed excellent internal consistency (0.90) and test-retest reliability (0.93). The factors showed a pattern of association with crossgender identity, gender ideology, outness, felt stigma, self-esteem, and psychological distress consistent with moderate-to-good construct validity. Conclusion: Internalized transphobia can be conceptualized as four inter-related dimensions: pride in transgender identity (reverse scored), investment in passing as a cisgender person, alienation from other transgender people, and shame. The Transgender Identity Survey reliably assesses this construct, useful in research to understand the impact of minority stress on transgender people's health. It can also be used in clinical practice to assess internalized transphobia at intake and follow-up.

RESUMEN

PURPOSE: The purpose of this study was to investigate how maternal gesture relates to speech production by children with fragile X syndrome (FXS). METHOD: Participants were 27 young children with FXS (23 boys, 4 girls) and their mothers. Videotaped home observations were conducted between the ages of 25 and 37 months (toddler period) and again between the ages of 60 and 71 months (child period). The videos were later coded for types of maternal utterances and maternal gestures that preceded child speech productions. Children were also assessed with the Mullen Scales of Early Learning at both ages. RESULTS: Maternal gesture use in the toddler period was positively related to expressive language scores at both age periods and was related to receptive language scores in the child period. Maternal proximal pointing, in comparison to other gestures, evoked more speech responses from children during the mother-child interactions, particularly when combined with wh-questions. CONCLUSION: This study adds to the growing body of research on the importance of contextual variables, such as maternal gestures, in child language development. Parental gesture use may be an easily added ingredient to parent-focused early language intervention programs.
