Visual-stress-related cortical excitability as a prospective marker for symptoms of depression and anxiety in young people.

Visual stress is thought to reflect cortical excitability and has been associated with many neurological, neuropsychiatric, and neurodevelopmental conditions. However, its relationships with symptoms of depression and anxiety have not yet been elucidated. We conducted two separate studies to first examine visual stress in a longitudinal community sample of 104 participants (aged 12-24) in association with prospective symptoms of depression, anxiety, and distress after 3 months, and subsequently in a cross-sectional epidemiological sample of 530 participants (aged 15-24) to validate its associations with current mood and distress symptoms. The Pattern Glare Test was used to examine visual stress to three grating patterns with the spatial frequencies (SF) of 0.3, 2.3, and 9.4 cycles per degree (cpd). Other known factors of mental health, including functioning, as well as resilience, hopelessness, and loneliness, were also assessed at baseline. In both studies, we showed that perceptual distortions were highest toward the pattern with mid-SF (2.3 cpd). Multiple linear regression analyses revealed that greater visual stress was significantly associated with not only baseline but also 3-month symptom outcomes, even when accounting for age, years of education, days of no functioning, resilience, hopelessness, and loneliness. Our findings suggest the importance of visual stress in understanding and predicting poor mental health outcomes. As mental health can lead to far-reaching consequences that extend to adulthood, our findings may inform state-of-the-art innovative strategies for the prediction of poor mental health outcomes and suggest visual stress as a potential marker for early risk detection among young people.

Ideational factors associated with consistent use of insecticide-treated nets: a multi-country, multilevel analysis.

BACKGROUND: Malaria remains a major cause of morbidity and mortality in sub-Saharan Africa. Using insecticide-treated nets (ITNs) every night, year-round is critical to maximize protection against malaria. This study describes sociodemographic, psychosocial, and household factors associated with consistent ITN use in Cameroon, Côte d'Ivoire and Sierra Leone. METHODS: Cross-sectional household surveys employed similar sampling procedures, data collection tools, and methods in three countries. The survey sample was nationally representative in Côte d'Ivoire, representative of the North and Far North regions in Cameroon, and representative of Bo and Port Loko districts in Sierra Leone. Analysis used multilevel logistic regression and sociodemographic, ideational, and household independent variables among households with at least one ITN to identify correlates of consistent ITN use, defined as sleeping under an ITN every night the preceding week. FINDINGS: Consistent ITN use in Côte d'Ivoire was 65.4%, 72.6% in Cameroon, and 77.1% in Sierra Leone. While several sociodemographic and ideational variables were correlated with consistent ITN use, these varied across countries. Multilevel logistic regression results showed perceived self-efficacy to use ITNs and positive attitudes towards ITN use were variables associated with consistent use in all three countries. The perception of ITN use as a community norm was positively linked with consistent use in Cameroon and Côte d'Ivoire but was not significant in Sierra Leone. Perceived vulnerability to malaria was positively linked with consistent use in Cameroon and Sierra Leone but negatively correlated with the outcome in Côte d'Ivoire. Household net sufficiency was strongly and positively associated with consistent use in all three countries. Finally, the findings revealed strong clustering at the household and enumeration area (EA) levels, suggesting similarities in net use among respondents of the same EA and in the same household. CONCLUSIONS: There are similarities and differences in the variables associated with consistent ITN use across the three countries and several ideational variables are significant. The findings suggest that a social and behaviour change strategy based on the ideation model is relevant for increasing consistent ITN use and can inform specific strategies for each context. Finally, ensuring household net sufficiency is essential.

Community-based antiretroviral therapy (ART) delivery for female sex workers in Tanzania: intervention model and baseline findings.

To increase linkage to and retention in antiretroviral therapy (ART) care, we piloted a community-based, ART service delivery intervention for female sex workers (FSWs). At baseline, we recruited and collected data from 617 FSWs (intervention: 309; comparison: 308) who were HIV positive and not on ART. This paper presents (1) the description of the intervention model, and (2) key descriptive and bivariate-level findings of the baseline FSW cohort. The data showed more than half of FSWs had a non-paying sex partner, and less than one-third used a condom at last sex with paying and non-paying clients, which suggest potentially high levels of HIV transmission. In addition, there is a gap in HIV testing and treatment because one-third learned about their HIV-positive status only at study enrollment, and among FSWs who had known their status for more than a month, half had not registered in care. This substantiates the importance of timely HIV diagnosis and treatment. A community-based ART program may serve as an important strategy in closing the HIV care and treatment gap for FSWs.

"Protect Your Loved Ones From Fataki": Discouraging Cross-Generational Sex in Tanzania.

The Fataki campaign aired in Tanzania via radio from 2008 to 2011 to address cross-generational sex, a major driver of HIV in the region. The campaign sought to incite social disapproval of men who engage in such relationships, generate dialogue around the issue, and encourage community interventions in these relationships through social learning. Using qualitative methods, we explored campaign reactions, use of the term Fataki to describe men in relationships with much younger women, and the nature of discussions spurred by the campaign. We conducted focus group discussions and individual interviews in Iringa and Pwani regions with young women, older men, and community leaders. Results showed that the Fataki term was widely used and had negative connotations reflecting social disapproval of men who participate in such relationships. Dialogue spurred by the campaign, primarily directed toward young women, focused on reasons for avoiding these relationships. We conclude with suggestions for relevant future interventions.

An assessment of HIV testing in Tanzania to inform future strategies and interventions.

This study identified characteristics of Tanzanians who have never tested for HIV in order to inform localized interventions to increase HIV testing coverage and uptake. A total of 3257 randomly selected participants aged 18-49 years were surveyed in 16 Mainland regions. Those surveyed were asked about demographics, HIV risk perception, HIV testing behavior, knowledge of both their own and partner's HIV status, and if they were tested with their partner. Approximately 22% of women and 46% of men reported never testing for HIV, with those who are younger (18-24 years), single/never married, living in rural areas, less educated, and having multiple sexual partners in the past year less likely to have tested. The gender differences in HIV testing behavior identified are supported by existing research. No association was found in either gender between HIV risk perception and testing, however, those least likely to test were those with multiple sex partners. These findings can help better target localized interventions focused on younger, single people, and those with multiple sex partners.

Unveiling the silence: women's sexual health and experiences in Nepal.

Rising rates of HIV in Nepal signal an impending epidemic. In order to develop culturally appropriate and effective actions and programmes to reduce HIV transmission, it is necessary to understand attitudes, behaviours and norms surrounding sexual networking and safer-sex practices in Nepal. Nepali women are thought to be at increased risk of sexually transmitted infections (STIs) and HIV, sexual violence and exploitation and other sexual health disparities due to cultural scripts limiting access to education, ability to control sexual relationships and acceptability in discussing sex and sexual health. The present study comprises a series of interviews with 25 women living in Kathmandu (13 individual interviews and 2 focus-group discussions) about their knowledge and experiences related to sex and sexual health. Interviews were translated and transcribed and two independent coders conducted a thematic analysis. Overall, the women described sex as primarily a male domain. Sex and sexual health were viewed as taboo discussion topics and formal sex education was perceived as minimally available and far from comprehensive in its scope. This formative study can inform future interventions aimed at reducing the spread of STIs/HIV in Nepal and empowering women on issues of sexual health and well-being.

Impact of smartphone overuse on 1-year severe depressive symptoms and momentary negative affect: Longitudinal and experience sampling findings from a representative epidemiological youth sample in Hong Kong.

Smartphone overuse can have detrimental impacts on youth mental health. How it may be longitudinally associated with depressive symptoms and functioning, and with daily momentary affect, remains to be investigated. A total of 3,033 young people were consecutively recruited from a large-scale epidemiological youth mental health study in Hong Kong. A subsample (n = 936) was followed-up after 1 year, with experience sampling data collected from 177 participants. Separate multivariable logistic regression models were applied to examine the prospective associations between smartphone overuse and depressive symptoms, with multilevel models fitted to examine its associations with momentary affect. The prevalence of smartphone overuse in the Hong Kong youth population was 29.3%. Smartphone overuse was significantly associated with more depressive symptoms and functional impairments both cross-sectionally and longitudinally. The associations between smartphone overuse and 1-year depressive symptoms were significant, even when accounting for baseline symptoms, social media use, and other risk and protective factors. Baseline depressive symptoms, in contrast, were not associated with 1-year smartphone overuse after adjusting for baseline smartphone overuse. Smartphone overuse was also significantly associated with higher levels of momentary negative affect, even when accounting for depressive symptoms. Strategies to mitigate the impact of smartphone overuse can have important long-term implications.

Trends in handwashing behaviours for COVID-19 prevention: Longitudinal evidence from online surveys in 10 sub-Saharan African countries.

Handwashing is essential for respiratory virus prevention, but uptake of handwashing in the context of the SARS-CoV-2 pandemic remains under-explored. This study examines trends in and determinants of handwashing practices for COVID-19 prevention in 10 countries in West, East, and Southern Africa. Data are derived from an online global Facebook survey assessing COVID-19 knowledge, attitudes, and practices, fielded in July (Round 1) and November 2020 (Round 2). Adults ≥18 years (N = 29,964) were asked if they practiced handwashing with soap and water in the past week to prevent COVID-19. Design-corrected F-statistics compared knowledge and practice of handwashing, at country and regional levels, between survey rounds. A country-level fixed-effects logistic regression model then identified socio-demographic and ideational correlates of handwashing at Round 2. Most participants were >30 years-old, men, post-secondary educated, and urban residents. Between survey rounds, handwashing prevalence declined significantly across regions and in each country, from a 14% decline (Δ84%-70%) in Tanzania to a 3% decline (Δ92%-89%) in South Africa. Handwashing was higher among participants aged >30 years (Adjusted Odds Ratio [aOR] = 1.25, 95% confidence interval [95%CI]: 1.15-1.35) and with post-secondary education (aOR = 1.62, 95%CI: 1.49-1.77) but lower among men (aOR = 0.71, 95%CI: 0.64-0.78). Ideational factors associated with handwashing included perceived effectiveness of handwashing (aOR = 2.17, 95%CI: 2.00-2.36), knowing someone diagnosed with COVID-19 (aOR = 1.28, 95%CI: 1.18-1.40), and perceived importance of personal action for COVID-19 prevention (aOR = 2.93; 95%CI: 2.60-3.31). Adjusting for socio-demographic and ideational factors, country-level marginal probabilities of handwashing ranged from 67% in Tanzania to 91% in South Africa in Round 2. COVID-19 prevention messages should stress the importance of handwashing, coupled with mask use and physical distancing, for mitigating respiratory disease transmission. Behaviour change communications should be sensitive to resource heterogeneities in African countries, which shape opportunities for sustainable handwashing behaviours.

Content analysis of online product descriptions from cannabis retailers in six US states.

BACKGROUND: As the purchase of cannabis becomes legalized in US states, cannabis marketing presents an unexplored regulatory landscape. Research examining other consumer products indicates marketing informs consumer product perceptions, use expectancies, and behavior. The current study examined how cannabis products are described on US cannabis retailer websites. METHODS: We used the National Cannabis Industry Association website to identify 27 retailers, linked to brick-and-mortar locations in six states, who advertised cannabis flower products online, and thematically coded descriptions of each product sold (N=428). RESULTS: Cannabis strain product descriptions fell into six categories: psychoactive effects, physical effects, social effects, sensory profile, therapeutic and curative claims, and negatives/warnings. Relaxation/stress relief (47.4%) and happiness (43.9%) were the most commonly described psychoactive effects, and relaxation/sedation was the most common physical effect (41.6%). Many products noted sensory characteristics, such as fruity (38.1%) or sweet (31.3%) taste/smell. A significant number of retailers claimed that strains could relieve pain and depression. Reports of potential side effects or warnings were less common. CONCLUSION: Online cannabis retailers are making potentially unsubstantiated product claims. Future work should examine the potential for these claims to inform consumer behavior. Regulations should ensure that cannabis labeling does not mislead consumers or promote unsafe use.

Health and Academic Consequences of Sexual Victimization Experiences among Students in a University Setting.

The current study examines the association between multiple interpersonal violence victimization types experienced in a university setting and the consequences for each type. Students at a mid-Atlantic university (n = 3977) completed a survey in 2015 assessing attitudes, experiences, consequences of (physical, behavioural, academic, mental), and university resources and reporting procedures for sexual assault, harassment, and intimate partner violence. Effect on mental health was the most cited consequence for all victimization types. Sexual harassment was reported by the largest number of students but with smaller percentages of students reporting consequences, while the opposite was true for sexual assault and multiple forms of abuse (smaller numbers experiencing; larger percentages reporting consequences). In the adjusted models, being in an abusive/controlling relationship and sexual harassment were significantly associated with physical health consequences (ps < .001). Sexual harassment was the only predictor of substance use (p < .001). Being an undergraduate and experiencing an abusive/controlling relationship, sexual harassment, or assault were associated with sexual risk behaviour (all ps < .05). These findings point to a need for holistic approaches to helping students heal from interpersonal victimization-approaches that include mental health services, attention to increased substance use and sexual risk, and monitoring academic performance.
