Sexting and Mental Health: A School-based Longitudinal Study Among Youth in Texas

Background: Sexting has emerged as a common socio-cultural problem in our society today. Few studies have estimated the prevalence of sexting among younger middle school youth and even fewer have assessed the relationship between sexting and mental health outcomes like anxiety and depression symptoms among middle school youth. Objectives: To estimate the prevalence of sexting among sixth and seventh-grade middle school students in a large urban school district in Southeast Texas and to assess its relationship with mental health outcomes (both anxiety and depression) among these youth. Methods: A retrospective analysis of an existing three-year randomized, two-arm, nested longitudinal study was conducted. Associations between sexting and depression symptoms; and sexting and anxiety symptoms were assessed via univariate and multivariate logistic analysis. Results: The prevalence of sexting among sixth graders was found to be 12%. Compared to youth who were not engaged in sexting, engagement in sexting was associated with significantly increased odds of depression and anxiety symptoms. Conclusion: Sexting is common among youth and is associated with poorer mental health outcomes such as anxiety and depression among these youth, but further validation of these findings is needed

Cannabis use and anxiety: is stress the missing piece of the puzzle?

OBJECTIVE Comorbidity between anxiety and cannabis use is common yet the nature of the association between these conditions is not clear. Four theories were assessed, and a fifth hypothesis tested to determine if the misattribution of stress symptomology plays a role in the association between state-anxiety and cannabis. METHODS Three-hundred-sixteen participants ranging in age from 18 to 71 years completed a short online questionnaire asking about their history of cannabis use and symptoms of stress and anxiety. RESULTS Past and current cannabis users reported higher incidence of lifetime anxiety than participants who had never used cannabis; however, these groups did not differ in state-anxiety, stress, or age of onset of anxiety. State-anxiety and stress were not associated with frequency of cannabis use, but reported use to self-medicate for anxiety was positively associated with all three. Path analyses indicated two different associations between anxiety and cannabis use, pre-existing and high state-anxiety was associated with (i) higher average levels of intoxication and, in turn, acute anxiety responses to cannabis use; (ii) frequency of cannabis use via the mediating effects of stress and self-medication. CONCLUSION None of the theories was fully supported by the findings. However, as cannabis users reporting self-medication for anxiety were found to be self-medicating stress symptomology, there was some support for the stress-misattribution hypothesis. With reported self-medication for anxiety being the strongest predictor of frequency of use, it is suggested that researchers, clinicians, and cannabis users pay greater attention to the overlap between stress and anxiety symptomology and the possible misinterpretation of these related but distinct conditions

Challenging structures: gender transformative interventions by livestock CRP in Ethiopia

IntroductionThis study is a review of secondary literature that has been synthesized to extract information and demonstrate the implementation and impact of community conversations (CCs) on gender aspects of social norms in livestock-based systems in Ethiopia.MethodsThe study used the phenomenological method of qualitative literature review to sketch the gender transformative approach to the delivery of knowledge products in a program on transforming the small ruminant value chain. The CC aimed at addressing gender-related norms in the division of labor, resource ownership, and handling practices of animals and their products previously identified, and those that emerged during the CC events across the study sites. A total of 1,517 community members (out of which 574 are women) took part in various CC events.Results and discussionThe review shows that the gender-related norms addressed were in line with the identified constraining norms faced by women livestock keepers in the mixed and livestock-based systems. The CC approach adopted complied with the stages laid out in literature: identification of existing knowledge; imparting new knowledge; knowledge integration and application; and review, reflection, and re-planning. The process was inclusive and community-engaging, which possibly cultivated intrinsic motivation and ownership of the process. Changes in knowledge, attitudes, and practices at household, community, and institutional levels were identified. The conclusions include institutionalizing the gender transformative approach in the public agricultural extension system. This could be facilitated by the generation of robust objective evidence of impacts and guidance for subsequent scaling at local, regional, and national levels

Pathways to Empowerment: Case Studies of Positive Deviances in Gender Relations in Ethiopia

Development eforts have increased women’s perceived empowerment and free dom, yet have failed to sustainably alter gender norms. There is a lack of research investigating reasons for this anomaly. This study, departing from the conventional approach, tries to fll this gap by employing an interpretative phenomenological approach to assess how women have managed to achieve expanded agency while living within a constraining normative environment. We argue that women have the capacity to deviate and the intentions that lead to new behaviors emerge not only from individuals’ attitudes, subjective norms, and perceived behavioral con trol, as suggested by the Theory of Planned Behavior, but also in combination with demographic and economic factors. Individuals need to make decisions in three ar eas ―self-conviction (attitude and perceived behavioral control), subjective norms (within household and community), and structures (state and non-state institutions). The results shed light on alternative empowerment pathways that could potentially inform the design of transformational interventions

Small ruminant value chain and empowerment: a gendered baseline study from Ethiopia

Introduction: Despite growing interest in gender analysis in value chains, comparatively few studies have analyzed gender relations in small ruminant value chains using sex-disaggregated quantitative data in livestock-based systems. Methods: Drawing on baseline data from the Small Ruminant Value Chain Development Program (SRVD) in Ethiopia, this study aims to address two research questions: what is the gender status along small ruminant value chain stages and the related associations among aspects of empowerment and socio-economic variables? We employed empowerment and value chain frameworks to address these research questions. Results and conclusion: Our findings reveal that small ruminant market participation, related decisions, and control over income are gender differential. Estimation results identified several variables significantly associated with agency dimensions, achievements, or both, with mixed results. These are age group, context, being married, being men and head of household, participation in breeding stock selection, livestock ownership, contact with extension agents, access to market information, and participation in selling at marketplaces. Participation in a small ruminant value chain may encourage more egalitarian decision-making behaviors but does not guarantee the capacity to make autonomous decision-making, and thus needs to be coupled with interventions on empowerment dimensions. Nevertheless, further investigations are required to establish the mixed results with additional variables on norms

The Longitudinal association Between Sexual Violence Victimization and Sexual Risk Behavior in adolescence

Being a victim of sexual violence (SV) is generally believed to be associated with subsequent sexual risk behavior (SRB) during adolescence. While this assumption makes intuitive sense, it is based on methodologically limited research, including a reliance on cross-sectional data. to address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with self-reported SRB approximately two years later. The sample comprised 4,618 youth (58% female; 52% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected using an audio computer-assisted self-interview (ACASI). Baseline data were collected when students were in 7th or 8th grade and follow-up data were collected approximately 24 months later when students were in 9th or 10th grade. Indices of SRB included behaviors related to oral, vaginal, and anal sex (e.g., number of partners, number of times without a condom). Girls, but not boys, who reported SV victimization at baseline reported engaging more frequently in all oral and vaginal SRBs at 24 month follow-up compared to their non-victimized female counterparts. Additionally, girls reporting SV victimization reported more anal sex partners than non-victimized girls. Girls who are victims of SV engage in significantly more SRB by early high school placing them at greater risk to contract STIs and become pregnant. Victims of SV should be screened for SRB and provided access to the appropriate resources. Teen pregnancy and STI prevention planning should consider SV victimization in their strategy planning

Human gut Bacteroidetes can utilize yeast mannan through a selfish mechanism

Yeasts, which have been a component of the human diet for at least 7000 years, possess an elaborate cell wall α-mannan. The influence of yeast mannan on the ecology of the human microbiota is unknown. Here we show that yeast α-mannan is a viable food source for Bacteroides thetaiotaomicron (Bt), a dominant member of the microbiota. Detailed biochemical analysis and targeted gene disruption studies support a model whereby limited cleavage of α-mannan on the surface generates large oligosaccharides that are subsequently depolymerized to mannose by the action of periplasmic enzymes. Co-culturing studies showed that metabolism of yeast mannan by Bt presents a ‘selfish’ model for the catabolism of this recalcitrant polysaccharide. This report shows how a cohort of highly successful members of the microbiota has evolved to consume sterically-restricted yeast glycans, an adaptation that may reflect the incorporation of eukaryotic microorganisms into the human diet

MRI T2 mapping assessment of T2 relaxation time in desmoid tumors as a quantitative imaging biomarker of tumor response: preliminary results

ObjectivesBecause size-based imaging criteria poorly capture biologic response in desmoid-type fibromatosis (DF), changes in MRI T2 signal intensity are frequently used as a response surrogate, but remain qualitative. We hypothesized that absolute quantification of DF T2 relaxation time derived from parametric T2 maps would be a feasible and effective imaging biomarker of disease activity.MethodsThis IRB-approved retrospective study included 11 patients with DF, managed by observation or systemic therapy, assessed by 3T MRI. Tumor maximum diameter, volume, and T2-weighted signal intensity were derived from manual tumor segmentations. Tumor:muscle T2 signal ratios were recorded. Two readers measured tumor T2 relaxation times using a commercial T2 scanning sequence, manual ROI delineation and commercial calculation software enabling estimation of reader reliability. Objective response rates based on RECIST1.1 and best responses were compared between size-based and signal-based parameters.ResultsMedian patient age was 52.6 years; 8 subjects were female (73%). Nine patients with longitudinal assessments were followed for an average of 314 days. Median baseline tumor diameter was 7.2 cm (range 4.4 - 18.2 cm). Median baseline T2 was 65.1 ms (range 40.4 - 94.8 ms, n=11); median at last follow-up was 44.3 ms (-32% from baseline; range 29.3 - 94.7 ms, n=9). T2 relaxation times correlated with tumor:muscle T2 signal ratios, Spearman p=0.78 (p<0.001). T2 mapping showed high inter-reader reliability, ICC=0.84. The best response as a percentage change in T2 values was statistically significant (mean -17.9%, p=0.05, paired t-test) while change in diameter was not (mean -8.9%, p=0.12).ConclusionsAnalysis of T2 relaxation time maps of DF may offer a feasible quantitative biomarker for assessing the extent of response to treatment. This approach may have high inter-reader reliability
