Feasibility, Acceptability, and Preliminary Effects of a Video-Based Intervention for Smoking Cessation Among People with HIV in Kathmandu, Nepal: A Single-Armed Pilot Study.

Despite the evidence of the disproportionate burden of tobacco use among people with HIV (PWH), little effort has been made to design and test smoking cessation interventions for PWH in resource-limited countries. We assessed the feasibility, acceptability, and preliminary effects of a video-based smoking cessation intervention consisting of eleven 3-8-minute sessions among PWH in Nepal, a lower-middle-income country. Guided by the phased-based model, our 3-month intervention focused on setting the quit date, smoking cessation, and abstinence maintenance. We screened 103 PWH over three weeks for our single-arm trial, with 53 considered eligible and 48 recruited (91%). Forty-six participants watched all video clips, while two watched 7-9. All participants were retained at a 3-month follow-up. The 1-week point prevalence abstinence (self-report supported with expired carbon monoxide levels < 5ppm) at 3-month follow-up was 39.6%. Most (90%) participants reported "very much" or "much" comfort with watching the videos on their smartphones, and all would recommend the intervention to other PWH who smoke. Overall, our pilot trial demonstrated the feasibility, acceptability, and high-level efficacy of the video-based smoking cessation intervention highlighting its potential for scaling up in Nepal and other resource-limited countries.

Dietary transition among Sub-Saharan Africa women post-immigration and during pregnancy.

BACKGROUND: Black immigrant women experience high risks for maternal complications, and some of these complications are related to dietary outcomes. This study aimed to explore Sub-Saharan African (SSA) pregnant women's dietary patterns and dietary transition post-immigration and during pregnancy. METHODS: We used a narrative design with a Photovoice approach and collected data through semi-structured interviews, digital food diaries, and Photovoice interviews. We recruited eleven participants (n = 11) through community gatekeepers and analyzed data using a constructivist grounded theory approach with constant comparative methods. RESULTS: The changes in food processes and participants' reactions to these changes generated a dietary transition model with three stages: perplexity, deliberation, and acceptance. (1) Perplexity was caused by different food characteristics such as taste, texture, and options. (2) Participants described deliberation as a process of deciding the kind of foods/cooking styles that would be an integral part of their regular diet. All participants opted for what they referred to as the 'African diet.' (3) Acceptance was characterized by participants' resolve to figure out how to make their chosen types of food and eating habits 'work' for themselves and their families. CONCLUSION: This study emphasizes the importance of having a sense of self-efficacy, a positive attitude, and community support in enabling migrant women to navigate dietary transition until they are satisfied with newly constructed eating habits. This determination, along with community support and persistent connection to their home culture, might help immigrants resist dietary acculturation and maintain healthy cultural eating habits, which is particularly important during pregnancy, given the impact of diet on maternal and neonatal outcomes. These findings underscore the need for collaborating with migrants from SSA to develop culturally tailored dietary interventions focused on each stage of dietary transition. Future studies should include focus group discussions to leverage women's shared experiences and create knowledge/information exchange opportunities.

Inflammation in Relation to Intensity and Duration of Cigarette Smoking Among People Living with HIV.

Both inflammation and smoking are independent predictors of morbidity and mortality among people living with HIV (PLHIV). As smoking burden is likely to exacerbate inflammation, we tested the hypothesis that higher intensity and longer duration of smoking are positively associated with C-reactive protein (CRP, an inflammatory marker) among 284 PLHIV in Kathmandu, Nepal. We measured smoking status, intensity of smoking, smoking duration, and CRP concentrations. In total, 22.9% of never smokers, 24.3% former smokers, and 34.1% current smokers had high CRP (> 3 mg/l). The median intensity and duration of smoking were 12 (cigarettes/day) and 19 years, respectively. Intensity of smoking (beta for increase in number of cigarettes/day: ß = 0.245; p = 0.017), smoking duration (beta for 1-year increase in smoking: ß = 0.341; p = 0.013), and pack-years of smoking (beta for 1-pack-years of smoking increase: ß = 0.351; p = 0.002) were each positively associated with CRP concentrations. While quitting is important, reducing the intensity and duration of smoking until quitting might be helpful in reducing the levels of inflammation, thereby in mitigating HIV-related harms.

Social and Emotional Wellbeing (SEW) Intervention for Mental Health Promotion Among Resettled Bhutanese Adults in Massachusetts.

Preventative behavioral interventions aimed at reducing mental problems among refugees are limited. We assessed the effect of a Social and Emotional Wellbeing (SEW) intervention on health-promoting behaviors (coping, social-networking, and conflict-resolution) and health-outcomes (stress, anxiety, and depression) among resettled Bhutanese adults in Western Massachusetts. The study was a community-based SEW intervention with pre-posttest evaluation among 44 Bhutanese adults in Western Massachusetts. The SEW is a culturally tailored 5-week, once-weekly health-education, problem solving, and mind-body exercise program to promote stress management skills. We used validated scales to measure outcomes. Mean scores of mental problems decreased by 5.9 for depression, 9.0 for anxiety, and 5.0 for stress post-intervention (p < 0.01). Mean scores increased by 27.3 for coping, 10.6 for social support, and 20.4 for conflict-resolution. Mean social-network scores increased by 4.6 for family, 4.7 for friends, and 1.8 for community networks (p < 0.01). Our Bhutanese participants reported improvement in their mental health after attending SEW intervention.

Healthy Diet Perceptions of Pregnant Women from Sub-Saharan Africa Residing in the U.S.

Several consumers lack a clear understanding of what makes a healthy diet. This uncertainty may be worsened by immigration due to socio-cultural differences. The purpose of this study was to explore Sub-Saharan African (SSA) pregnant women's perceptions of a healthy diet and the sources of dietary information available to them in the context of immigration. We used narrative interviews and photo-food diaries, followed by photo-elucidated interviews to obtain data. Participants defined and illustrated a healthy diet as having four characteristics: (a) Familiar, (b) balanced, (c) made of fresh and organically grown ingredients, and (d) able to build the consumer's body. Participants indicated that the overwhelming nature of dietary information made it difficult to navigate. Participants trusted dietary recommendations offered by family and peers the most, while those offered by health care providers were reported to be difficult to understand or incorporate due to not being culturally specific. This paper highlights the importance of considering consumers' socio-cultural backgrounds and building partnerships between health care providers and the communities they serve to design culturally relevant dietary education.

Improving Mental Health in Refugee Populations: A Review of Intervention Studies Conducted in the United States.

Mental health is one of the most pervasive health concerns in the refugee population due to the combined effects of traumatic experiences prior to migration and post-migration stressors related to resettlement. The objectives of this systematic search were to synthesize evidence on the effectiveness and identify gaps of mental health interventions on mental health outcomes for refugees resettled in the United States. This review search identified a combination of quasi-experimental (7 studies) and qualitative research studies (5 studies). Twelve papers, published between 2003-2017, evaluating twelve different interventions, were selected for review. Studies were conducted in a variety of refugee populations: Africans (8), Southeast Asians (2), Bhutanese (1), and multicultural (1). Interventions included groups/workshops (10) and individual counseling (2). The results from the mental health interventions showed increases in health confidence, health seeking behaviors, consistency with treatment course, English proficiency, quality of life, and level of enculturation. Results also showed decreases in depression and psychological distress. Also identified from this review were different methods for interventions including linguistic and ethnically-matched facilitators versus non-matched facilitators, as well as group interventions versus non-group interventions. These differences were identified in the review and discovered to be areas for further research as these items were not often addressed in the literature.

Sociocultural Perceptions and Enablers to Seeking Mental Health Support Among Bhutanese Refugees in Western Massachusetts.

This qualitative study aimed to identify cultural influences on seeking mental health support among Bhutanese refugees resettled in Western Massachusetts. Bhutanese refugees aged 18 years or older were recruited for eight focus group discussions, organized by age and gender ( N = 67, 49.3% female, mean age = 38, SD = 15.9). The PEN-3 cultural model was used as the theoretical framework to examine the roles of cultural perceptions that influence mental health-seeking behaviors. Focus group discussions were audio taped to facilitate the thematic-analysis. Younger participants (<35 years) reported experiencing stressors relating to economic hardships and difficulties in developing academic and social skills as they juggle breadwinner and care-giving responsibilities for their families. Older participants reported frustration with the difficulties in learning English and increased dependence on their children. Family members provided the initial frontline support to persons with mental health problems. If family support did not work, they consulted with their relatives and trustworthy community members for further assistance. Psychological factors such as fears of emotions, social norms, beliefs, and self-esteem associated with cultural norms and values influenced seeking mental health support. All participants expressed the need to have a culturally tailored intervention to develop acquired skills to improve their self-esteem and self-efficacy in order to integrate into their new social and cultural environment. Because family members make important decisions about seeking mental health support, involving family members in developing and delivering culturally appropriate skill development interventions could be a potential strategy to reduce their stress and increase resilience in this refugee community.

C-reactive protein and depression in persons with Human Immunodeficiency Virus infection: the Positive Living with HIV (POLH) Study.

BACKGROUND: Human Immunodeficiency Virus (HIV) infection has been frequently associated with chronic inflammation as well as depression. C-reactive protein (CRP) is positively associated with depression in people without HIV infection. We tested the hypothesis of an independent relationship between CRP and depression in a cohort of HIV-positive people. METHODS: A cross-sectional survey was conducted among 316 HIV-positive people (181 men and 135 women) aged 18-60years residing in the Kathmandu Valley, Nepal. The latex agglutination turbidimetric method was used to measure serum CRP concentrations and the Beck Depression Inventory (BDI)-I method was used to measure depression, with a cut off of ⩾20 indicating likely depression. The relationship between CRP concentrations and depression symptoms was assessed using both multiple linear regression analysis and multiple logistic regression analysis, with adjustment for potential socio-demographic, cardiovascular, life-style, and HIV-related clinical and treatment confounding factors. RESULTS: Twenty-six percent participants (men: 23%; women: 29%) met criteria for depression. In multiple regression analysis, the authors observed a linear relation between serum CRP concentrations and BDI score (beta for 1 unit change in ln(CRP)=1.13, p=0.001) in HIV-positive participants. In a logistic regression analysis, participants with serum CRP levels>3mg/L had a 2.3-fold higher odds of depression symptoms compared to those with serum CRP level⩽3mg/L (p=0.005). In analyses stratified by sex, associations were stronger in men than in women. For example, CRP>3mg/L was associated with a 3.6-fold higher odds of depression in men (p=0.002), while in women the odds ratio was 1.7 (p=0.33). CONCLUSION: We found a linear relationship between serum CRP concentrations and depression symptoms score in HIV-positive people, and evidence that risk of depression is elevated among HIV-positive men with a high level of inflammation (CRP>3mg/L). Further prospective study to confirm the role of inflammation in depression among HIV-positive people is warranted.

"Nobody does checkups back there": A qualitative study of refugees' healthcare needs in the United States from stakeholders' perspectives.

The number of refugees globally grew to 35.3 million in 2022, and many refugees are exposed to various health risks along their migration journey. As a result, they may arrive in host communities with numerous health issues, including communicable diseases and chronic and mental health conditions. Navigating the healthcare system in a host country proves to be a significant challenge for them, leading to delayed care. This qualitative study explored the convolute healthcare needs of refugees in the United States by soliciting insights from stakeholders involved in refugee resettlement and healthcare. In-depth interviews were conducted with fifteen stakeholders who work closely with refugees, including healthcare providers, cultural/clinical health navigators supporting refugees, staff from refugee resettlement agencies and governmental entities, and researchers studying refugee health. Following informed consent, interviews were audio-recorded, transcribed verbatim, and imported into MAXQDA 2022 (VERBI Software) for thematic analysis. The results revealed key themes, including the heterogeneity of refugee populations, limited awareness of preventive healthcare, high prevalence and suboptimal management of chronic conditions, complexity of the healthcare system, lack of follow-up, and language barriers. Further research is warranted concerning the long-term health of refugee populations in the United States. Additionally, more tailored programs involving peer educators are recommended to support refugee communities in navigating the complex healthcare system in the host country.

Dietary patterns and suicide in Japanese adults: the Japan Public Health Center-based Prospective Study.

BACKGROUND: Although dietary patterns have been linked to depression, a frequently observed precondition for suicide, no study has yet examined the association between dietary patterns and suicide risk. AIMS: To prospectively investigate the association between dietary patterns and death from suicide. METHOD: Participants were 40 752 men and 48 285 women who took part in the second survey of the Japan Public Health Center-based Prospective Study (1995-1998). Dietary patterns were derived from principal component analysis of the consumption of 134 food and beverage items ascertained by a food frequency questionnaire. Hazard ratios of suicide from the fourth year of follow-up to December 2005 were calculated. RESULTS: Among both men and women, a 'prudent' dietary pattern characterised by a high intake of vegetables, fruits, potatoes, soy products, mushrooms, seaweed and fish was associated with a decreased risk of suicide. The multivariable-adjusted hazard ratio of suicide for the highest v. lowest quartiles of the dietary pattern score was 0.46 (95% CI 0.28-0.75) (P for trend, 0.005). Other dietary patterns (Westernised and traditional Japanese) were not associated with suicide risk. CONCLUSIONS: Our findings suggest that a prudent dietary pattern may be associated with a decreased risk of death from suicide.

Serum Selenium and Inflammation in Individuals with Human Immunodeficiency Virus Infection.

HIV infection has been linked to selenium deficiency and chronic inflammation. Both selenium deficiency and inflammation have been associated with poor health outcomes among individuals with HIV. However, the role of serum selenium levels in inflammation has not been studied among individuals with HIV. We assessed the relationship of serum selenium levels to C-reactive protein (CRP), a marker of inflammation, in individuals with HIV in Kathmandu, Nepal. In this cross-sectional study, we measured the normal serum CRP and selenium levels of 233 individuals with HIV (109 women and 124 men) using the latex agglutination turbidimetric and atomic absorption methods, respectively. We used multiple linear regression analysis in examining the association of serum selenium levels with CRP adjusting for sociodemographic and clinical parameters, including antiretroviral therapy, CD4+ T cell count, chronic diseases, and body mass index. The geometric means of CRP and selenium levels were 1.43 mg/liter and 9.65 µg/dL, respectively. Overall, serum selenium levels were inversely associated with CRP levels (ß for one unit change in log selenium; ß = -1.01, p = .06). Mean CRP levels significantly decreased with increasing selenium across selenium tertiles (p for trend = .019). The mean serum CRP levels were 40.8% lower in the highest selenium tertile than in the lowest. Our study suggests that high serum selenium levels may reduce serum CRP levels in individuals with HIV, although a longitudinal study is warranted to establish causality.

Mental health disorders among Middle Eastern immigrant women living in the United States: A scoping review.

PURPOSE: This review aims to describe the up-to-date knowledge of the prevalence of mental health disorders among Middle Eastern immigrants women living in the United States (U.S.) and the factors affecting mental health status. CONCLUSION: High prevalence of mental health disorders and low utilization of mental health services among Middle Eastern immigrants were reported. The factors affecting mental health disorders included socio-demographics, immigration-related factors, and previous mental and physical health problems. PRACTICE IMPLICATIONS: Further research is needed to understand the factors affecting mental health disorders and attitudes associated with the utilization of mental health services among Middle Eastern women in the U.S.

Mental health promotion among resettled Bhutanese adults in Massachusetts: Results of a peer-led family-centred Social and Emotional Well-being (SEW) intervention study.

Family-centred interventions addressing sociocultural and emotional stressors promise to prevent mental health problems among refugees in the United States. Peer-led strategies are highly valued, as they engage communities and promote the sustainability of interventions. We assessed the effects of a peer-led family-centred Social and Emotional Well-being (SEW) intervention on preventive (coping, social networking and conflict resolution) and mental health outcomes (stress, anxiety and depression) among resettled Bhutanese adults in Massachusetts. We conducted a SEW intervention with a pre-intervention versus post-intervention (7-day) and follow-up (3-month) evaluation among 103 adults (50 families). The SEW is a culturally tailored 5-weekly session program that included health education, problem-solving and mind-body exercises to increase knowledge and skills regarding stress management and conflict resolution. We measured anxiety and depression using the Hopkins Symptom Checklist-25 and stress using Cohen Perceived Stress scales. Health-promoting behaviours were measured using validated scales. We used paired t-tests for continuous and McNemar tests for categorical variables. Mean scores significantly decreased from pre-intervention to post-intervention and follow-up for stress by 15% and 13.9%, anxiety by 20.9% and 25.1% and depression by 18.7% and 20.4% (all p's < 0.01). Mean scores increased from pre-intervention to post-intervention and follow-up for coping by 10% and 17.2%, and for community networking by 28% and 36.8% (all p's < 0.01). Generalised estimating equations showed a significant reduction in stress, anxiety, depression and improved coping, self-efficacy, family and community networking scored from baseline to follow-ups (all p's < 0.01). Our peer-led family-centred SEW intervention was associated with improved preventive and mental health outcomes among Bhutanese adults.

Peer-led family-centred problem management plus for immigrants (PMP-I) for mental health promotion among immigrants in USA: protocol for a pilot, randomised controlled feasibility trial.

INTRODUCTION: Research is needed to investigate preventive strategies to reduce mental health burden and assess effective implementation among immigrants. Problem management plus (PMP) is a low-intensity multicomponent psychological intervention developed by the World Health Organization (WHO) that trained laypeople can deliver. PMP has been adapted as a prevention intervention and developed as PMP for immigrants (PMP-I), including psychoeducation, problem-solving, behavioural activations and mind-body exercise, to address immigrants' multiple stressors. This pilot trial aims to assess the feasibility and acceptability of PMP-I and provide a preliminary estimate of the difference between PMP-I versus community support services pamphlets on the primary outcomes of interest (stress, anxiety and depressive symptoms) to inform the design of a large-scale intervention. METHODS AND ANALYSIS: The feasibility and acceptability of PMP-I will be assessed by measuring recruitment, session attendance, retention rates, programme acceptability and the fidelity of intervention delivery. This pilot trial will test preliminary effects of PMP-I vs community support services pamphlets in a randomised controlled trial (N=232 participants from 116 families (2 members/family); 58 families randomised to condition intervention or control) on stress, anxiety and depressive symptoms (primary outcomes), chronic physiological stress assessed in hair cortisol (secondary outcomes), and coping, family conflict resolution, and social networking (targets), with assessment at baseline, postintervention and 3-month postintervention. Eligibility criteria for the primary study participants include Bhutanese ≥18 years resettled in Massachusetts with a score of ≤14 on the Patient Health Questionnaire-9. All family members will be invited to participate in the family-based intervention (one session/week for 5 weeks). Multilevel modelling will compare the longitudinal change in outcomes for each treatment arm. ETHICS AND DISSEMINATION: The Institutional Review Board of the University of Massachusetts Amherst approved this study (Protocol: 1837). Written informed consent will be obtained from all participants. The study results will be used to inform the design of a large-scale intervention and will be disseminated in peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER: NCT04453709.

Association between serum ferritin concentrations and depressive symptoms in Japanese municipal employees.

It remains unclear whether levels of body iron store are related to milder forms of depression, which are more common among apparently healthy people. We examined the association between serum ferritin concentrations and depressive symptoms among 312 men and 216 women working in two municipal offices in Japan. Depressive symptoms were assessed by using the Center for Epidemiologic Studies Depression (CES-D) scale. In men, increased prevalence of depressive symptoms (defined by using a cutoff value of ≥ 19) was significantly associated with decreased levels of serum ferritin. In age- and study-site-adjusted models, ORs (95% CIs) for depressive symptoms for men in first, second, third, and fourth quartiles of serum ferritin concentrations were 2.83 (1.01-7.94), 1.74 (0.87-3.49), 1.33 (0.71-2.47), and 1.00 (reference), respectively (p for trend=0.02). In multivariate-adjusted model, ORs (95% CIs) in first, second, third, and fourth quartiles of serum ferritin concentrations were 2.88 (0.93-8.91), 1.91 (0.90-4.05), 1.28 (0.66-2.49), and 1.00 (reference), respectively (p for trend=0.03). No significant association was detected in women. Our finding that men with lower levels of serum ferritin concentrations had a higher prevalence of depressive symptoms suggests that adverse psychological effects may be implicated in iron deficiency among middle-age Japanese workers.

Serum 25-hydroxyvitamin d concentrations and season-specific correlates in Japanese adults.

BACKGROUND: Several lines of evidence indicate an important role for vitamin D in the prevention of a range of diseases. Blood vitamin D levels show clear seasonal variation; however, data on the determinants of vitamin D status for each season are limited. We investigated the association between lifestyle and serum vitamin D concentration by season in Japanese workers. METHODS: Subjects were 312 men and 217 women aged 21 to 67 years who worked in municipal offices in Northern Kyushu, Japan and participated in a periodic checkup in July or November. Multiple linear regression analysis was used to examine the association between serum 25-hydroxivitamin D concentrations and lifestyle factors for each season. RESULTS: Mean serum 25-hydroxyvitamin D concentration was 27.4 ng/ml (68.4 nmol/L) and 21.4 ng/ml (53.4 nmol/L) for workers surveyed in July and November, respectively (P < 0.001); the prevalence of vitamin D deficiency (<20 ng/ml) was 9.3% and 46.7%, respectively (P < 0.001). In November, dietary vitamin D intake (in both sexes) and nonsmoking and physical activity (in men) were significantly associated with higher concentrations of serum 25-hydroxyvitamin D. In summer, fish/shellfish intake was associated with higher serum 25-hydroxyvitamin D concentrations in women. CONCLUSIONS: Vitamin D deficiency is common in Japanese workers during seasons with limited sunlight. The lifestyle correlates of favorable vitamin D status in November were physical activity, dietary vitamin D intake, and nonsmoking.

Physicians are a key to encouraging cessation of smoking among people living with HIV/AIDS: a cross-sectional study in the Kathmandu Valley, Nepal.

BACKGROUND: HIV care providers may be optimally positioned to promote smoking behaviour change in their patients, among whom smoking is both highly prevalent and uniquely harmful. Yet research on this front is scant, particularly in the developing country context. Hence, this study describes smoking behaviour among people living with HIV/AIDS (PLWHA) in the Kathmandu Valley of Nepal, and assesses the association between experience of physician-delivered smoking status assessment and readiness to quit among HIV-positive smokers. METHODS: We conducted a cross-sectional survey of PLWHA residing in the Kathmandu Valley, Nepal. Data from 321 adult PLWHA were analyzed using multiple logistic regression for correlates of current smoking and, among current smokers, of motivational readiness to quit based on the transtheoretical model (TTM) of behaviour change. RESULTS: Overall, 47% of participants were current smokers, with significantly higher rates among men (72%), ever- injecting drug users (IDUs), recent (30-day) alcohol consumers, those without any formal education, and those with higher HIV symptom burdens. Of 151 current smokers, 34% were thinking seriously of quitting within the next 6 months (contemplation or preparation stage of behaviour change). Adjusting for potential confounders, experience of physician-delivered smoking status assessment during any visit to a hospital or clinic in the past 12 months was associated with greater readiness to quit smoking (AOR = 3.34; 95% CI = 1.05,10.61). CONCLUSIONS: Roughly one-third of HIV-positive smokers residing in the Kathmandu Valley, Nepal, are at the contemplation or preparation stage of smoking behaviour change, with rates significantly higher among those whose physicians have asked about their smoking status during any clinical interaction over the past year. Systematic screening for smoking by physicians during routine HIV care may help to reduce the heavy burden of smoking and smoking-related morbidity and mortality within HIV-positive populations in Nepal and similar settings.

Knowing the consequences of unprotected sex with seroconcordant partner is associated with increased safer sex intentions among HIV-positive men in Kathmandu, Nepal.

Unprotected sexual intercourse among HIV-positive people can adversely affect their own health by increasing their exposure to multiple strains of HIV-1 or other sexually transmitted infections (STIs). The study explored the relationship between knowledge of Nepalese HIV-positive men about the consequences of having unprotected sex with seroconcordant partners and their intention to practise safer sex with such partners. In total, 166 participants recruited conveniently in the Kathmandu Valley, Nepal, were interviewed. Each participant reported intention to practise safer sex with seroconcordant partners, knowledge about the consequences of having unprotected sex with seroconcordant partners, perceived partner-related barriers to condom-use, belief that condoms interfere with sex, and condom-use self-efficacy. Of the 166 participants, 50.6% intended to practise safer sex every time they have sex with seroconcordant partners. Results of multiple logistic regression analysis showed that the participants who were aware of the possibility of HIV superinfection [adjusted odds ratio (AOR)=2.93, 95% confidence interval (CI) 1.16-7.34, p = 0.022)] or that the presence of STIs in HIV-positive persons increases progression of HIV disease (AOR = 2.80, 95% CI 1.08-7.26, p = 0.033) were more likely to intend to practise safer sex with seroconcordant partners. Similarly, the participants who were employed or who had lower levels of belief that condoms interfere with sex were more likely to intend to practise safer sex. The findings suggest that improving the knowledge of HIV-positive persons about the consequences of having unprotected sex with seroconcordant partners might improve their intention to practise safer sex with such partners.

High prevalence and genotype distribution of hepatitis C virus in people living with HIV in Kathmandu, Nepal.

BACKGROUND: Hepatitis C virus (HCV) co-infection is still a significant cause of morbidity and mortality among HIV-positive individuals in many resource-limited countries. As prevalence rates of co-infection using the serological diagnosis of HCV infection might be imprecise, estimates of prevalence using polymerase chain reaction (PCR) confirmed diagnosis is needed to guide HCV treatment efforts among HIV-positive individuals in resource-limited countries. METHODS: We conducted this community-based cross-sectional study among 280 HIV-positive individuals recruited through the networks of five non-government organizations working with HIV-positive individuals in Kathmandu, Nepal. We collected blood samples from each participant and tested all the anti-HCV positive samples for HCV-RNA and genotypes. We calculated the prevalence of HCV/HIV co-infection and examined factors associated with it using multivariable logistic regression analysis. We also calculated the proportion of infection by different HCV genotypes and investigated HCV seroconversion. RESULTS: The prevalence of HCV/HIV co-infection was 29.6% (95% CI 24.25-34.95). History of a lifetime injecting drug use was associated with a higher likelihood of HCV/HIV co-infection (p < .001). Of the 81 individuals whose serum samples were available for genotype assessment, 55.7% tested positive for genotype 3A, 36.7% for genotype 1A and the remaining samples' genotype was undetermined (7.6%). Of the 100 anti-HCV positive samples, 17 (17.0%) tested negative for HCV RNA. CONCLUSIONS: High prevalence of HCV/HIV co-infection, distribution of prevalent HCV genotype 1A and 3A and HCV seroconversion rate have important implications for the public health system in guiding HCV treatment and control efforts among HIV-positive individuals.

Assessing the quality of service of village malaria workers to strengthen community-based malaria control in Cambodia.

BACKGROUND: Malaria continues to be a major public health problem in remote forested areas in Cambodia. As a national strategy to strengthen community-based malaria control, the Cambodian government has been running the Village Malaria Worker (VMW) project since 2001. This study sought to examine the nature and quality of the VMWs' services. METHODS: Data collection was carried out in February and March 2008 through interviews with one of the two VMWs who takes the lead in malaria control activities in each of the 315 VMW villages (n = 251). The questionnaire addressed 1) the sociodemographic characteristics of VMWs, 2) service quality, 3) actions for malaria prevention and vector control, and 4) knowledge of malaria epidemiology and vector ecology. RESULTS: VMWs were effective in conducting diagnosis with Rapid Diagnostic Tests (RDTs) and prescribing anti-malarials to those who had positive RDT results, skills that they had acquired through their training programmes. However, most other services, such as active detection, explanations about compliance, and follow-up of patients, were carried out by only a small proportion of VMWs. The variety of actions that VMWs took for malaria prevention and vector control was small (average action index score 12.8/23), and their knowledge was very limited with less than 20% of the VMWs giving correct answers to six out of seven questions on malaria epidemiology and vector ecology. Knowledge of vector breeding places and malaria transmission were significant determinants of both the quality of VMWs' services and the variety of their actions for malaria prevention and vector control. CONCLUSIONS: VMWs' services focused primarily on diagnosis and treatment. Their focus needs to be broadened to cover other aspects of malaria control in order to further strengthen community-based malaria control. VMWs' actions and knowledge also need substantial improvement. Strengthening training programmes can help achieve better performance by VMWs.
