Prevalence and associated factors of substance use disorders among people who use drugs: a population-based cross-sectional study in the Western Province of Sri Lanka

Introduction: This study aimed to assess the prevalence of substance use disorders and associated factors among people who use drugs in the Western Province of Sri Lanka. Methods: A cross-sectional study was conducted in the Western Province of Sri Lanka, using a respondent-driven sampling technique. Sampling was initiated with 20 seeds and peers were recruited by peers through handing out coupons. The number of recruited participants was proportional to the estimated number of people who use drugs in each district of Western Province. A total of 870 people who use drugs participated in the study. A validated Sinhala version of the Drug Abuse Screening Test was used to assess the drug use severity among the participants and a pre-tested validated questionnaire was used to collect data to assess the associated factors. RDS Analyst software version 0.64 was used to assess frequency estimates. To assess factors associated with substance use disorders multiple logistic regression analysis was performed using SPSS software version 22. Results: The median age of the study sample was 39 years. The incidence of substance use disorder among the sample was 88.4%. Being employed, using heroin as a psychoactive drug, using drugs daily, using more than one drug, being a heavy alcohol user, buying drugs, stealing money or exchanging goods to get drugs, spending a substantial amount per month on drugs (Rs > 40,001), past or present medical history of tuberculosis and those who had disclosed their drug use behavior to their immediate family were found to be significantly associated with an increased risk of having a substance use disorder. Conclusion: A high prevalence of substance use disorder was found in the sample with multiple economic, behavioral, and health-related risk factors.

Recruiting hard-to-reach populations via respondent driven sampling for mobile phone surveys in Colombia: a qualitative study

ABSTRACT Background Uptake of mobile phone surveys (MPS) is increasing in many low- and middle-income countries, particularly within the context of data collection on non-communicable diseases (NCDs) behavioural risk factors. One barrier to collecting representative data through MPS is capturing data from older participants. Respondent driven sampling (RDS) consists of chain-referral strategies where existing study subjects recruit follow-up participants purposively based on predefined eligibility criteria. Adapting RDS strategies to MPS efforts could, theoretically, yield higher rates of participation for that age group. Objective To investigate factors that influence the perceived acceptability of a RDS recruitment method for MPS involving people over 45 years of age living in Colombia. Methods An MPS recruitment strategy deploying RDS techniques was piloted to increase participation of older populations. We conducted a qualitative study that drew from surveys with open and closed-ended items, semi-structured interviews for feedback, and focus group discussions to explore perceptions of the strategy and barriers to its application amongst MPS participants. Results The strategy’s success is affected by factors such as cultural adaptation, institutional credibility and public trust, data protection, and challenges with mobile phone technology. These factors are relevant to individuals’ willingness to facilitate RDS efforts targeting hard-to-reach people. Recruitment strategies are valuable in part because hard-to-reach populations are often most accessible through their contacts within their social network who can serve as trust liaisons and drive engagement. Conclusions These findings may inform future studies where similar interventions are being considered to improve access to mobile phone-based data collection amongst hard-to-reach groups.

HIV treatment cascade among female sex workers in Ethiopia: Assessment against the UNAIDS 90-90-90 targets

Background HIV treatment cascades for HIV-positive female sex workers (FSWs) have been challenged by the overlapping stigma and discrimination associated with both their sex work and HIV status. This study aims to assess the proportion of HIV-positive FSWs who access care and treatment in Ethiopia. Method A cross-sectional study with a respondent-driven sampling technique was used to enroll 6,085 female sex workers from January to June 2020. Interviews were conducted to assess the FSWs’ HIV status awareness and access to ART. A blood sample was drawn to determine the current HIV status and viral load level. Logistic regression was run to identify factors associated with FSWs’ HIV status awareness. Results Of the total 1140 HIV-positive FSWs, 50.38% knew they were HIV positive; 92.88% of those who knew their status were on ART, and 91.68% of those on ART had attained viral suppression of less than 1000 copies per milliliter. The adjusted odds of knowing HIV status was 3.20 (95% CI; 2.00, 5.13) among those aged 35 years and older, 1.81 (95% CI; 1.05, 3.12) among widowed, and 1.73 (95% CI; 1.28, 2.32) in those who did not perceive the risk of HIV acquisition. Conclusion Only about half of HIV-positive FSWs knew they were HIV positive. More than 90% of those who knew their status were put on ART and achieved viral suppression. The weakest point in achieving HIV control among FSWs is the identification of those living with HIV.

A self-reported study: Health and mental health status among MSM in a district of North-West province

From youth to adulthood, men who have sex with men (MSM) experience a variety of challenges, including anxiety and depression. Their challenges are aggravated by their mental health condition, as they frequently suffer from depression, and yet they need to make informed decisions regarding their health without any limitation on access to health services. This study adopted a descriptive cross-sectional design using a quantitative approach. A sample of N=221 MSM aged 18-44 years old was recruited using a respondent-driven sampling technique (RDST). A structured, anonymous questionnaire was used to assess the mental health of the MSM. The online questionnaire data was entered into Excel and imported into Stata version 13.0 for analysis. The response rate was 92%. The findings of our study indicate that 46.61% of the respondents had mild to severe depression, while 53.39% did not experience depression. Contributing factors that lead the MSM to experience depression include their loss of respect in the community because they are MSM (p = 0.069), their families feeling ashamed of them (p = 0.068), and their experience of physical abuse (p = 0.006). Not being treated like other people in the health facility and in the community contributes to their not feeling that they belong (p = 0.250). The findings suggest that young MSM are at risk of developing depression and of being infected with HIV. The need has arisen to get more MSM to access health services and psychological support, since they are the most vulnerable key population.

Musculoskeletal disorders among dental students: a survey from Saudi Arabia

BackgroundWork-related musculoskeletal disorders (WMSD) are injuries affecting bones, joints, muscles, and tendons due to improper working conditions with serious consequences on health and career. Dentists were found to be at greater risk of developing WMSD compared to other healthcare providers. This study aimed to investigate the prevalence and risk factors of WMSD among dental students in Saudi Arabia.MethodsThis cross-sectional survey-based study recruited dental students across the kingdom using respondent-driven sampling technique. Data was collected using the Nordic Musculoskeletal scale and a validated, self- administered, close-ended questionnaire which assessed WMSDs predisposing factors, enabling factors and musculoskeletal disorders consequences and management. The questionnaire was administered in both Arabic and English languages and was distributed online using google forms. Data analysis was performed using SPSS, Chi-square test or Fisher Exact test was used where appropriate and Multivariate Logistic regression analysis was performed to identify predictors of developing WMSDs.ResultsThe prevalence of WMSD was 87% (95% CL; 83.9% to 90.3%) among the 462 respondents. Gender, study year, type of practice, having clinics for left-handed, hours of clinical practice, sitting in the proper position while working, use of coping strategies were significantly associated with WMSD prevalence (P < 0.05). Males were OR = 10 times at higher risk of WMSD compared to females (P = 0.0001). Those with daily clinical practice were OR = 5 times at higher risk of WMSD than those who have weekly practice. Those practicing walking, workout, and yoga showed lower prevalence of WMSD (OR = 0.377 & 0.323, p = 0.015, 0.010 respectively).ConclusionsThe prevalence of WMSD among dental students in KSA was high. Males and those with prolonged clinical sessions were at greater risk of WMSD. There is a need for awareness campaigns to educate dental students about risk factors of WMSD. Collegesy, dental colleges should adopt policies in reducing WMSD among their students.

The effect of drop-in centers on access to HIV testing, case finding, and condom use among female sex workers in Addis Ababa, Ethiopia.

Varied HIV prevention interventions involving multiple strategies has been instrumental in the effort to contain and lessen the prevalence of HIV around the globe. However, female sex workers (FSWs) often face stigma and discriminatory challenges, resulting in lower access to the HIV prevention initiatives. This study has aimed to assess the effect of one of the HIV service delivery models, the Drop-in Centers (DICs), which is designed to overcome the service uptake barriers of FSWs. A quasi-experimental study design was employed. A respondent-driven sampling technique was used to recruit 1,366 FSWs from January to June 2020. A propensity score matching technique was used to balance the potential confounders between FSWs who had access to DICs and those who had never accessed DICs. Comparisons of the effect of DIC on the outcome of interest was made using a logit regression model at a 5% level of significance. A total of 1,366 FSWs took part in the study. The analysis estimated the average treatment effects of access to DICs on four key outcomes: ever-testing to know HIV status, finding HIV-positive FSWs, awareness of HIV-positive status, and consistent condom use. A significant effect of DIC was seen at a 95% confidence interval on each outcome. Access to DIC produced a 7.58% increase in the probability of testing to know HIV status (P < 0.001), a 7.02% increment in finding HIV-positive FSWs (P = 0.003), an increase of 6.93% in awareness of HIV status among HIV positive FSWs (P = 0.001), and a 4.39% rise in consistent condom use (P = 0.01). Ensuring access of FSWs to DICs has led to an upsurge in HIV testing among FSWs, raising HIV status awareness among those who are HIV positive, and encouraged consistent condom use. To provide effective HIV prevention services, particularly to those FSWs living with HIV, it is essential to strengthen the services provided in DICs and expand the centers. This will ensure that the entire network of FSWs is reached with appropriate HIV prevention services.

All Shades of Green: The Anatomy of the Fridays for Future Movement in Italy

The Fridays for Future (FFF) movement has emerged as a critical force in environmental activism in response to pressing climate challenges. Despite its global prominence, few studies have delved deeply into the internal lines of thought within FFF communities. Our research fills this gap by exploring the diverse perspectives within the Italian FFF community and how these viewpoints influence the movement’s civic and political dedication to environmental sustainability. We are specifically interested in the shades of green, namely the internal variations of attitudes and beliefs of the FFF participants. We conducted empirical research with over 300 climate activists from the FFF movement in Italy, collecting data from March to October 2022 using a Web-based respondent-driven sampling technique (webRDS). The questionnaire, comprising 27 questions, covers topics such as political values, institutional trust, technological attitudes, climate knowledge, and personal lifestyles. We chose Multiple Correspondence Analysis (MCA) for our analysis due to its valuable mathematical properties, capability for producing insightful visual representations, and efficient computational features. The analysis reveals four distinct groups within the Italian FFF community based on their attitudes and actions related to environmental sustainability. These groups include Activist Equalizer, Disillusioned Technophobes, Institution Trustee, and Laissez-faire Solitaries, challenging the prevailing notion that FFF activists solely fit the profile of Activist Equalizers often depicted in media and public discourse. Findings offer a novel picture of the FFF movement in Italy and contribute to a better understanding of how the internal diversity of FFF impacts the efficacy and future trajectory of environmental activism. This research offers new insight into the political role of FFF and its potential influence on climate-related political actions.

Accumulation of Biological and Behavioral Data of Female Sex Workers Using Respondent-Driven Sampling: Protocol for a Systematic Review.

Respondent-driven sampling (RDS) is a nonprobability sampling technique that allows the extrapolation of its outcome to the target population. This approach is typically used to overcome the difficulties in studying hidden or difficult-to-reach groups. The purpose of this protocol is to generate a systematic review on the accumulation of biological and behavioral data of female sex workers (FSWs) through different surveys that use the RDS method from around the world in the near future. The future systematic review will discuss the initiation, actualization, and problems of RDS during the accumulation of biological and behavioral data of FSWs through surveys from around the world. The behavior and biological data of FSWs will be extracted from peer-reviewed studies published between 2010 and 2022 and that are acquired through RDS. Using PubMed, Google Scholar, the Cochrane database, Scopus, Science Direct, and the Global Health network, all papers that are available will be obtained using the search phrases "respondent-driven" and "Female Sex Workers" OR "FSW" OR "sex workers" OR "SW." According to STROBE-RDS (Strengthening the Reporting of Observational Studies in Epidemiology for Respondent-Driven Sampling) criteria, the data will be retrieved through a data extraction form and will be organized using World Health Organization classifications of areas. The Newcastle-Ottawa Quality Assessment Scale will be used to measure bias risk and overall study quality. The future systematic review that will be generated from this protocol will offer evidence for or against the claim that using the RDS technique to recruit participants from "hidden" or "hard-to-reach" populations is the best strategy. The results will be disseminated through a peer-reviewed publication. Data collection started on April 1, 2023, and the systematic review is expected to be published by December 15, 2023. A minimum set of parameters for specific methodological, analytical, and testing procedures, including RDS methods to evaluate the overall quality of any RDS survey, will be provided by the future systematic review, in accordance with this protocol, to assist researchers, policy makers, and service providers in improving RDS methods for the surveillance of any key population.

Gender Characteristics and Population Size Estimation of Transgender People: A Field-Based Study from Iran

Purpose: We determined the size of the transgender population in Shiraz, Iran. Methods: In this cross-sectional study, the respondent-driven sampling technique was used by choosing eight seeds, three waves, and six coupons for each participant. The estimated population size was calculated by wisdom of the crowds, multiplier, and successive sampling–population size estimation (SS-PSE) methods. Pooling of results was done by an Anchored Multiplier calculator. Results: The mean age of participants (n=200) was 22.7±4 years, 197 (98.5%) were single, 86 (43%) were educated <12 years, 25 (12.5%) were not living with their families, and 52 (26%) were not financially supported by their parents. The transgender population was estimated by the wisdom of the crowds, multiplier, and SS-PSE methods to be 300 (95% confidence interval [CI]: 200–400), 677 (95% CI: 655–696), and 665 (95% CI: 624– 677), respectively. Their prevalence was found to be 0.017% (95% CI: 0.011–0.022%), 0.038% (95% CI: 0.036–0.039%), and 0.037% (95% CI: 0.034–0.038) using the same methods, respectively. Pooled results revealed that 22–37 per 100,000 general population were transgender individuals. Weighted estimation showed that trans men (56.6%) are more prevalent than trans women (43.4%), and only 17% of transgender people succeeded in gender reassignment. Conclusion: Transgender people should not be considered as marginalized groups of the community; they should be respected, heard, and valued. Establishing a standard and routine procedure for the collection of data on the status of transgender people and gender identity is necessary for policymaking and intervention programs.

Violence exposure, mental distress, substance use behaviors, and overdose experiences among people who inject drugs

ABSTRACT Rates of exposure to traumatic events are up to two times higher among people with substance use disorders (SUDs) compared to the US general population. Overdoses (OD) and overdose fatalities have continued to increase nationally and in Kentucky and are associated with elevated trauma symptoms. This paper examines the impacts of witnessing and experiencing OD among people who inject drugs (PWIDs) in Kentucky. Study participants were recruited via Respondent-Driven Sampling techniques supplemented with direct community outreach. Our findings showed that participants reporting past year severe mental health distress and lifetime violence exposure had higher odds of both witnessing and experiencing OD. Additionally, participants who reported early abuse had higher odds of both witnessing and experiencing OD as did participants with early onset injection drug use. The study findings suggest the need for incorporating knowledge about trauma into policies, procedures, and practices in treating SUD among PWID.

Use of recommended personal protective equipment among Brazilian health professionals during the COVID-19 pandemic.

The COVID-19 pandemic is one of the biggest health crises in the world and the use of personal protective equipment (PPE) is significant measures to prevent the transmission of SARS-CoV-2. However, PPE needs to be used properly by healthcare professionals. To analyze the use of PPE among Brazilian health professionals and associated factors during a period of the COVID-19 pandemic. An analytical cross-sectional study was carried out from October to December 2020. For data collection, the respondent-driven sampling technique was used, adapted for social media, with a link to an online survey form. The study considered 12,086 Brazilian health professionals. Most (69%) used PPE recommended for the care of patients with suspected or diagnosed COVID-19. Factors associated with the use of PPE were: working in an Intensive Care Unit (ICU) or in a field hospital, receiving training, being provided with sufficient, high-quality PPE by the workplace and being an odontologist compared to nursing professionals. For procedures that generate aerosols in the context of COVID-19, 54.1% of them used the recommended PPE, the associated factors were: being married or in a stable relationship compared to a single/divorced professional, working in an ICU, being offered training, providing sufficient, high-quality PPE, and being an odontologist compared to nursing professionals. For the care of patients with COVID-19, 69% of health professionals used PPE properly, and several factors interfered with the use of this equipment.

HIV prevalence and associated factors among female sex workers in Ethiopia, east Africa: A cross-sectional study using a respondent-driven sampling technique.

SummaryBackgroundHIV acquisition among Female Sex Workers (FSWs) is 30 times higher than the acquisition rate among females in the respective general population. A higher HIV burden in FSWs challenges the prevention and control of the virus in other population groups. However, there is inadequate evidence on the burden of HIV among FSWs in Ethiopia. This study was conducted to assess the extent of HIV and associated factors among FSWs in the country.MethodsThis was a cross-sectional study that involved a total of 6,085 FSWs. The participants were selected using a respondent-driven sampling technique (RDS). FSWs who lived at the study sites for at least a month before the study time were considered eligible for recruitment. The study was conducted from January 01 to June 30, 2020 in 16 cities across Ethiopia. A mixed-effect logistic regression model was applied to determine factors associated with HIV positivity.FindingsThe pooled HIV prevalence among FSWs in this study was 18·7% (95% CI: 17·8, 19·7) with considerable variation across cities. The highest HIV prevalence was observed in Bahir Dar city, 28·2% (95% CI: 23·9, 33.0) and the lowest was seen in Shashemene city, 14.0% (95% CI: 10·2, 18·9). The odds of HIV positivity in FSWs was associated with being older than 35 years of age (AOR = 8·1; 95% CI: 6·1, 10·3), reactive for Treponema Pallidum (AOR = 2·6; 95% CI: 1·0, 3·4), being widowed (OR = 2·2; 95% CI: 1·6, 2·9), not able to read and write (OR = 2·0; 95% CI: 1·5, 2·4), incidence of condom breakage (OR = 1·5; 95% CI: 1·2, 1·7) and having a history of STIs (OR = 1·3; 95% CI: 1·1, 1·6).InterpretationOne in five FSWs was HIV positive. HIV prevalence was higher in the older age groups and in those who were positive for Treponema Pallidum (Syphilis). The findings indicated the importance of strengthening HIV prevention and control in FSWs to achieve the national goal to eliminate HIV by 2030.FundingThe study was supported by The Ethiopian Ministry of Health through the Federal HIV/AIDS Prevention and Control Office.

Factors associated with the use of personal protective equipment among Brazilian physicians during the COVID-19 pandemic.

The objective was to analyze the factors associated with use of Personal Protective Equipment (PPE) among Brazilian physicians during the COVID-19 pandemic. An analytical cross-sectional study was conducted from October to December 2020 with 1298 Brazilian physicians. The respondent driven sampling technique was used by sharing the survey through social media. Factors associated with the use of PPE while caring for COVID-19 patients were: being female (AOR = 1.57; 95% CI: 1.24-1.98; p ≤ 0.001); working in Intensive Care Unit (ICU) (AOR = 2.78; 95% CI: 2.06-3.75; p ≤ 0.001); training (AOR = 1.62; 95% CI: 1.25-2.09; p ≤ 0.001); access to sufficient PPE (AOR = 2.22; 95% CI: 1.27-3.90; p = 0.0050), and PPE of good quality (AOR = 1.84; 95% CI: 1.16-2.92; p = 0.009). The following factors were associated with the use of recommended PPE during procedures that generate aerosols in the context of COVID-19: working in the ICU (ORA=2.73; 95% CI: 2.06-3.62; p < 0.01); working in a field hospital (AOR = 1.37; 95% CI: 1.06-1.79; p = 0.018;) training (AOR = 1.72 95% CI: 1.32-2.24; p < 0.01); access to sufficient PPE (AOR = 1.63; 95% CI: 0.91-2.92; p < 0.01), PPE of good quality (AOR = 2.07; 95% CI: 1.28-3.35; p = 0.003). The factors associated with the use of necessary PPE with COVID-19 patients and for procedures that generate aerosols were identified. Educational interventions for professionals and managers must be implemented to direct them towards protecting themselves and others.

An investigation of the Sustainability of Village Savings and Loans Associations (VSLAs) amidst Covid-19 and its impact on household income levels: lessons from Malawi, Sub-Saharan Africa

BackgroundFood security, malnutrition, and poverty are some of the challenges that most of the sub-Saharan African countries have been historically facing. With the coming of Covid-19 pandemic, the sustainability of the Village Savings and Loans Association which are formed to counter fight these challenges is questioned.AimThis study aimed to assess factors associated with the Sustainability of VSLAs amidst Covid-19 and its impacts on households' income levels.MethodsAn online cross-sectional design was conducted from November to January 2021, targeting VSLAs members in Mzuzu. A snowball and respondent-driven sampling technique were used to recruit the needful participants using a referral approach. IBM SPSS version 23 was used to perform descriptive statistics, Chi-Square, and binary logistic regression with unstandardized Beta (β), Odds Ratios (OR), and 95% Confidence Interval (CI) being taken into account with P-value set at 0.1, 0.05 and 0.01 significance levels.ResultsOur study finds that household income declined by 54% for those earnings belonged to ˂ MK5,000, as compared to 38% and 15% for medium (MK5,000 ≥ MK10,000) and higher (> MK10,000) income bands respectively. Our study shows that gender (β = 0.437, p = 0.094), age-group (β = 1.317, p = 0.000), education (β = 2.181, p = 0.047), share contributions (β = 1.035, p = 0.008), meetings (β = 0.572, p = 0.021), occupation (β = -0.453, p = 0.106), and frequency of meeting (β = -0.507, p = 0.049) were positively and negatively statistically significant predictors.ConclusionAccording to the findings of this study, households with lower income earners, which is one of the indicators of poverty, are more affected by the pandemic than their counterparts. We urge that the Malawi governments should maintain and, if they haven't already, implement programs that support low-income households, such as transfer payments, which have been shown to uplift people out of income poverty in many developing countries.

Waste pickers’ perception of occupational hazards and well-being in a Nigerian megacity

ABSTRACT This study examined occupational risks associated with waste picking and pickers well-being in Lagos, Nigeria. A convenience sampling technique was employed to select 152 landfill-waste pickers, and the respondent-driven sampling technique was used to select 53 street-waste pickers. We discovered that waste pickers were exposed to occupational health risks such as body pain, tiredness, twisted ankles, chest pain, and eye soreness. Non-use of personal protective equipment contributed to waste pickers’ susceptibility to occupational health risks. Most waste pickers were dissatisfied with their well-being connected to the unhealthy conditions in which they work, the extreme poverty they live in, and the stigmatisation they experience. The study concludes that waste pickers’ well-being is critical for effective solid waste management; hence, they should be considered adequately in policy design and implementation programs/strategies.

Quality of Life and Community Wellbeing of Members Associated With Village Savings and Loans Associations as a Model of Sharing Economy in the Least Developing Countries: A Case of Mzuzu City in Northern Malawi, Southern Africa.

This study was aimed at examining the impacts of the Sharing economy on the individual and community Quality of Life (QOL) and wellbeing by looking at their associated influencing factors using Village Savings and Loans Associations as a model of sharing economy in Malawi. An online community-based cross-sectional study design was conducted from November 2020 through January 2021. In the survey, 402 Village Savings and Loans Associations (VSLAs) members from the Mzuzu City area participated, recruited using snowball and respondent-driven sampling techniques. The sample size was computed using a single population proportion using the Yamane formula. Descriptive statistics and ordinal logistic regression model techniques were also employed. Additionally, we used the Chi-Square test, two-way ANOVA, and Ordinal regression model to determine statistical associations between socioeconomic data and QOL and wellbeing variables with a 5% level of significance. On the aspect of community wellbeing, the findings of our study indicated that income (levels and disposal) provided members with options to live a better QOL and wellbeing within the community by either facilitating payment for better education, eating healthier foods, acquiring assets, etc. Further, the absence of discrimination provided a platform for voice, inclusion, and social trust, enhancing freedom of expression. We also found that education facilitated better earnings and knowledge of public health-related issues. As for the contribution to the sharing economy, our study has emphasized the role played by trust in enhancing sharing economy. We recommend and encourage people to join these VSLAs so as to improve their QOL and wellbeing. However, there is a need to replicate the study on a larger scale to validate our study findings for effective policy formulation and implementation geared to improving the overall quality of people’s lives. Based on these findings, we further recommend that authorities reinstate programs like National Strategy for Financial Inclusion 2016–2020 and Savings and Loan Groups Best Practice Guidelines (SLG BPGs) 2016–2017 that could further enhance the future of VSLAs, which are vital for QOL and community wellbeing of the people in developing countries like Malawi.

Online medical teaching during COVID-19: Perspectives from teachers and taught.

BACKGROUND:Online teaching has been practiced after lockdown due to Coronavirus Disease 2019 (COVID-19) pandemic which has replaced conventional classroom teaching. The aim of the present study was to know the perceptions regarding online learning as perceived by both teachers and students during COVID-19 pandemic.MATERIALS AND METHODS:The present study was cross-sectional and questionnaire-based. Web-based respondent-driven sampling technique was used to recruit participants for the present study. Three hundred and thirty-two students and 130 teachers of varying ages and gender participated in the study. The link of web-based questionnaire was sent to respondents through WhatsApp/Facebook. Responses from all the participants were tabulated and analyzed using univariate analysis (Chi-square test).RESULTS:Prerecorded lectures (38.9%) and Webinar apps (35/8%) were the most common modules of online teaching by students. One-third (34.3%) had the convenience to attend lectures from home whereas 44.3% had difficulty in concentration. Commonly cited disadvantage by students was inability to do practical work (37.9%). Regarding teaching faculty, 43.8% had no prior knowledge of online teaching. Sixty percent of teachers had 4 h/week of online teaching. No face-to-face interaction (67.7%) and internet issues (26.9%) were commonly stated barriers by faculty.CONCLUSION:The pandemic has pushed the teachers and students toward newer teaching avenues. However, more needs to be done to supplement the existent teaching pattern and preparedness of teaching faculty by incorporating online assignments and assessment methods, strengthening digital infrastructure in medical schools, and training support for teachers.

1.L. Workshop: Assessment of substance abuse in different populations

Abstract Substance abuse is a growing public mental health issue. Recent data from Global Burden of Disease study demonstrate that age standardized DALYs rate attributed to drug use disorders has increased by 25% in age group of 25-49 years during 1990-2019 (Lancet 2020; 396 1204-22). Standardized DALY rate due to alcohol use disorders reduced by 1/5 in this age group during the last 30 years, however it remains among the top 20 causes leading to greatest losses of DALYs in this age group. European countries persist to have high burden of diseases due to substance abuse. Social ecological model enables to structure individual, family, community and broader societal risk factors for substance abuse in specific groups within society. Some European countries (e.g. Germany) face increased migration especially from the war affected countries like Syria. Respective refugees and migrants may demonstrate higher substance abuse (alcohol and drug abuse) prevalence as an outcome of traumatic exposures and reflect the attempts to escape past and present experiences. In other countries (e.g. Lithuania), who still reflect transitional societies, substance abuse rates remain high due to psychosocial stress and structural barriers to implement effective prevention. Identification of risk factors may alleviate targeted and tailored prevention. The aim of the workshop is to systematize substance abuse risk factors in specific population groups based on socio-ecological framework applying different methodological approaches. There is a knowledge gap in culturally sensitive and translated into different languages instruments which assess substance use in refugee populations, especially from the Arabic countries. Therefore, a systematic review results on culturally sensitive substance abuse screening and assessment instruments among refugee populations will be presented. The qualitative study conducted in Germany will provide findings and insights on substance abuse perceptions among Syrian migrants and refugees. Understanding the explanatory model of Syrian refugees could inform future interventions to prevent substance abuse and design tailored interventions. Assessment of the behavioral risk factors related to injecting dug use in Lithuanian population using respondent driven sampling technique will be presented. Identifying individual and social risk factors may lead to targeted and effective prevention. Key messages Context specific knowledge of substance use is necessary for prevention including past and present factors. As refugee populations continue to grow, adequate screening instruments for substance abuse/dependence are needed.

Rapid situational assessment of people who inject drugs (PWID) in Nairobi and coastal regions of Kenya: a respondent driven sampling survey

BackgroundA Cross-sectional Rapid Situational Assessment of People Who Inject Drug (PWIDs) applying Respondent Driven sampling techniques (RDS) was used to recruit subjects/participants in a study aimed at assessing HIV prevalence and risk behaviors among injecting drug users in Nairobi and Coastal regions of Kenya. There is paucity of data and information on injecting drug use in sub-Saharan Africa and there is sufficient evidence of existence of the environment for development and growth of injecting drug use. Past studies on PWID and its association to HIV and AIDS that have been conducted in Kenya do not provide sufficient information to support effective planning and comprehensive national response to the HIV and AIDS epidemic.MethodsA cross-sectional study design was adopted in which a set of initial subjects referred to as ‘seeds’ were first identified from which an expanding chain of referrals were obtained, with subjects from each wave referring subjects of subsequent waves. The seeds were drawn randomly from the population and interviewed to pick the one with the largest network and other unique characteristics. A maximum of twelve seeds were recruited. The second stage involved conducting assessment visits to the sites to identify potential collaborators that included non-governmental organizations (NGOs), drug treatment centres, health facilities, community based organizations (CBO’s) among others. Three NGOs located in the coast region and one in Nairobi region were identified to assist in identifying drug injection locations and potential participants. Key informant interviews (KIIs) and Focus Group Discussions (FGDs) were also conducted using interview guides.ResultsA total of 646 individuals (344 in Nairobi and 302 at the coast) were recruited for the study between January and March 2010. Of these 590 (91%) were male and 56 (9%) were female. Findings showed that most PWIDs initiated injecting drug use between the ages of 20–29 years, with the youngest age of initiation being 11 years and oldest age being 53 years. Most commonly injected drug was heroin (98%), with a small (2%) percentage injecting cocaine. Other non-injecting methods such as smoking or combining these two drugs with other drugs such as cannabis or Rohypnol were also common. Most PWIDs used other substances (cigarettes, alcohol, and cannabis) before initiating injecting drug use. The adjusted national HIV prevalence of PWIDs was 18.3% (19.62% unadjusted) with PWIDs in Nairobi region registering 18.33% (20.58% unadjusted) compared PWIDs for Coastal region indicating 18.27% (18.59% - unadjusted). The gender based HIV prevalence showed that women were more at risk of acquiring HIV (44.51%-adjusted) compared to men (15.97%-adjusted). The age specific HIV prevalence showed that PWIDs who initiated injecting at 11–19 years (44.7% adjusted) were most at risk in Nairobi compared to those who initiated injecting at age 20–24 years (23.2% - adjusted) in the coastal region. While all PWIDs continue to be at risk in the two regions, those from the Western parts of Nairobi, Kenya were at a relatively higher risk given their increased propensity for sharing injecting equipment and solutions.ConclusionsCompared to the national HIV prevalence of (4.9%), the results show that People Who Inject Drugs (PWIDs) are at particularly high risk of infection in Kenya and there is urgent need for intervention (KenPHIA, 2018). This study also showed clear evidence that 70% of PWIDs are primary school educated, engage in high risk injecting and sexual behaviors comprising sharing of injecting equipment, unprotected heterosexual and homosexual sex. Given that initiation of injecting drug use begins early and peaks after formal school years (20–29 years), prevention programmes should be targeted at primary and secondary school students, college and out of school youth. Further, to protect People who inject drugs (PWIDs) from HIV infection, the country should introduce free Needle Syringe Programs (NSP) with provision of condoms and Methadone Assisted Therapy (MAT) as a substitute for drug use.

Disclosure of Sexual Orientation and its Predictors among HIV-Positive Men Who Have Sex with Men in a Contemporary African Setting.

Background:Sexual orientation disclosure has been reported to promote good peer support, improve psychological health, as well as access to STIs and HIV prevention services. Hence, this study sought to assess the level of disclosure sexual orientation and its predictors among HIV-positive men who have sex with men (MSM) in Plateau state Nigeria.Methods:This was a cross-sectional study design conducted between October 2018 and December 2019 among 114 HIV-infected MSM through respondent driven sampling technique. Epi Info version 7 was used for the data analysis with adjusted odds ratio and 95% confidence interval (CI) used as point and interval estimates on the logistic regression model and P < 0.05 considered statistically significant.Results:The mean age of the respondents was 26.0 ± 5.4 years with disclosure of sexual orientation to nonpartner being reported by 45 (39.5%). Positive family history of same sex practice was found to significantly predict self disclosure of sexual orientation (adjusted odds ratio: 3.30; 95% CI: 1.2356–8.8038; P = 0.017).Conclusions:This study has revealed a low level of disclosure of sexual orientation among HIV-positive MSM in Plateau state with a positive family history of same sex involvement as its predictor.
