Background:Sharing of needles and syringes and unprotected sex remain a common practice among people who inject drugs (PWID) in India and are important drivers of new HIV infections. Whether engagement in risk behaviors among PWID is associated with symptoms of common mental disorders in India is unknown. Methods:We analyzed the data collected in April and May of 2012 from a community-based sample of 420 PWID in Delhi using time location sampling. Self-report symptom scales were used to measure the severity of symptoms of depression (Patient Health Questionnaire 9) and anxiety (Generalized Anxiety Disorder scale 2) within the preceding 2 weeks. We assessed the presence of suicidal thoughts within the past 12 months. Results:PWID with severe depressive symptoms and those with suicidal thoughts were 4 and 2 times more likely to share needles/syringes, respectively. PWID experiencing suicidal thoughts had 82% more female sexual partners and were 5 times more likely to have had unprotected sex at last sex with a paid female partner. Conversely, symptoms of anxiety were associated with a 30% decrease in the likelihood of needle/syringe sharing and a 70% decrease in the likelihood of unprotected sex at last sex with a paid female partner. Conclusions:We found a high prevalence of symptoms of depression, anxiety, and suicidal ideation among men who inject drugs in Delhi and that depression and suicidal ideation are independently positively associated with HIV risk behaviors, whereas anxiety is associated with a reduction in such behaviors. Ameliorating mental health problems among PWID in India may aid in reducing HIV infections.

BackgroundDengue remains an important cause of morbidity in Laos. Good knowledge, attitudes and practices (KAP) among the public regarding dengue prevention are required for the success of disease control. Very little is known about dengue KAP among the Lao general population.MethodsThis was a KAP household survey on dengue conducted in a peri-urban Pak-Ngum district of Vientiane capital, Laos. A two-stage cluster sampling method was used to select a sample of participants to represent the general community. Participants from 231 households were surveyed using an interviewer-administered questionnaire.ResultsAlthough 97% of the participants heard of dengue, there was a lack of depth of knowledge on dengue: 33% of them did not know that malaria and dengue were different diseases, 32% incorrectly believed that Aedes mosquito transmits malaria, 36% could not correctly report that Aedes mosquitoes bite most frequently at sunrise and sunset; and < 10% of them recognized that indoor water containers could be Aedes mosquito breeding sites. Attitude levels were moderately good with a high proportion (96%) of participants recognizing that dengue was a severe yet preventable disease. Self reported prevention methods were quite high yet observation of the participants’ yards showed use of prevention methods to be only moderate. The majority (93%) of the interviewees did not believe that they had enough information on dengue. There was an association between good knowledge and better practices, but good knowledge was associated with worse attitudes.ConclusionsThere is a lack of depth of knowledge regarding dengue in Pak-Ngum community and observation methods revealed that more needs to be done by community members themselves to prevent the spread of Aedes mosquitoes.

HIV risk behaviours among injecting drug users in Northeast India following scale-up of a targeted HIV prevention programme

Gregory Armstrong; Chumben Humtsoe; Michelle Kermode

BackgroundIn the Northeast Indian states of Manipur and Nagaland there has been an ongoing HIV epidemic among injecting drug users (IDUs) since the mid-1990s. Project ORCHID is an Avahan-funded HIV prevention project that has been working in selected districts of Manipur and Nagaland since 2004. It supports local partner non-government organisations (NGOs) to deliver a range of harm reduction interventions, and currently reaches approximately 14,500 IDUs across the two states. To assess changes in HIV risk behaviours two Behavioural Tracking Surveys (BTS) were undertaken among IDUs in 2007 and 2009.MethodsThe BTS used respondent driven sampling (RDS) to recruit adult male IDUs (18 years of age and above) from Ukhrul and Chandel districts in Manipur, and Kiphire and Zunheboto districts in Nagaland. This paper reports on analysis of socio-demographics, drug use and injecting practices, sexual behaviour and condom use, knowledge of HIV, and exposure to interventions. Descriptive data were analysed using RDSAT, and odds ratios were calculated in SPSS.ResultsThe proportion of IDUs reporting NOT sharing needles / syringes at last injection increased substantially in Ukhrul (59.6% to 91.2%) and Zunheboto (45.5% to 73.8%), remained high in Chandel (97.0% to 98.9%), and remained largely unchanged in Kiphire (63.3% to 68.8%). The use of condoms with regular partners was low in all districts at both time points. In Ukhrul, Kiphire and Zunheboto the proportion of IDUs using condoms during sexual intercourse with a casual partner increased substantially to approximately 70-85%, whilst in Chandel the increase was only marginal (57.4% to 63.6%). Exposure to NGO HIV prevention interventions was significantly associated (p<0.05) with lower odds of sharing needles during the previous month (Nagaland, OR=0.63; Manipur, OR 0.35).ConclusionDespite district-level differences, the results from this BTS study indicate that exposure to HIV prevention services, predominately delivered in this region by NGOs, is associated with a reduced likelihood of engaging in HIV risk behaviours. IDUs using HIV prevention services are more likely to engage in safe injecting and sexual practices, and effort is required to sustain / increase opportunities for IDUs to access these services. These outcomes are a noteworthy achievement in a very challenging context.

BackgroundThere is good evidence for the effectiveness of opioid substitution therapy (OST) for injecting drug users (IDUs) in middle and high-income countries but little evidence regarding the provision of OST by non-government organisations (NGOs) in resource-poor settings. This paper reports on outcomes of an NGO-based OST program providing sub-lingual buprenorphine to opiate dependent IDUs in two north-east Indian states (Manipur and Nagaland), a region where conflict, under-development and injecting of heroin and Spasmoproxyvon (SP) are ongoing problems. The objectives of the study were: 1) to calculate OST treatment retention, 2) to assess the impact on HIV risk behaviours and quality of life, and 3) to identify client characteristics associated with cessation of treatment due to relapse.MethodsThis study involves analysis of data that were routinely and prospectively collected from all clients enrolled in an OST program in Manipur and Nagaland between May 2006 and December 2007 (n = 2569, 1853 in Manipur and 716 in Nagaland) using standardised questionnaires, and is best classified as operational research. The data were recorded at intake into the program, after three months, and at cessation. Outcome measures included HIV risk behaviours and quality of life indicators. Predictors of relapse were modelled using binary logistic regression.ResultsOf all clients enrolled in OST during the month of May 2006 (n = 713), 72.8% remained on treatment after three months, and 63.3% after six months. Statistically significant (p = 0.05) improvements were observed in relation to needle sharing, unsafe sex, incidents of detention, and a range of quality of life measures. Greater spending on drugs at intake (OR 1.20), frequently missing doses (OR 8.82), and having heroin rather than SP as the most problematic drug (OR 1.95) were factors that increased the likelihood of relapse, and longer duration in treatment (OR 0.76) and regular family involvement in treatment (OR 0.20) reduced the likelihood of relapse.ConclusionThe findings from this operational research indicate that the provision of OST by NGOs in the severely constrained context of Manipur and Nagaland achieved outcomes that are internationally comparable, and highlights strategies for strengthening similar programs in this and other resource-poor settings.

Knowledge and attitudes of doctors regarding the provision of mental health care in Doddaballapur Taluk, Bangalore Rural district, Karnataka

Joshua Cowan; Shoba Raja; Amali Naik; Gregory Armstrong

BackgroundSpecialist mental health care is out of reach for most Indians. The World Health Organisation has called for the integration of mental health into primary health care as a key strategy in closing the treatment gap. However, few studies in India have examined medical practitioners’ mental health-related knowledge and attitudes. This study examined these facets of service provision amongst doctors providing primary health care in a rural area of Karnataka is Southern India.MethodsA mental health knowledge and attitudes questionnaire was self- administered by participants. The questionnaire consisted of four sections; 1) basic demographics and practice information, 2) training in mental health, 3) knowledge of mental health, and self-perceived competence in providing mental health care, and 4) attitudes towards mental health. Data was analysed quantitatively, primarily using descriptive statistics.ResultsThis study recruited 46 participants. The majority of participants (69.6%) felt competent in providing mental health services to their patients. However, there was a substantial level of endorsement for several statements that reflected negative attitudes. Almost one third of participants (28.0%) had not received any training in providing mental health care. Whilst three-quarters of participants correctly identified depression (76.1%) and psychosis (76.1%) in a vignette, fewer were able to name three common signs and symptoms of depression (50.0%) and psychosis (28.3%).ConclusionsIntegrating mental health into primary health care requires evidence-based up-skilling programs. Doctors in this study desired such training and would benefit from it, with a focus on both depth of knowledge and uncovering stigmatising attitudes towards people with mental health problems.

BackgroundThere is a concentrated HIV epidemic among female sex workers (FSWs) in the state of Nagaland, located in the north-east of India. Local non-government organisations (NGOs) are supported by the National State AIDS Control Society (NSACS) and the Avahan-funded Project ORCHID (Avahan is the India AIDS initiative of Bill & Melinda Gates Foundation in India) to deliver a range of interventions to FSWs including safe sex promotion, condom distribution, and testing and treatment of sexually transmitted infections (STIs). The commercial hub of Nagaland, Dimapur, is an important transportation node, and hosts a concentration of FSWs. This paper reports on comparative analysis of Integrated Behavioural and Biological Assessment (IBBA) data collected from FSWs in Dimapur in 2006 and 2009 to assess changes in condom use, HIV testing, and exposure to interventions.MethodsTwo IBBA cross-sectional surveys were undertaken among FSWs in Dimapur in 2006 (Round 1) and 2009 (Round 2) using an interviewer-administered questionnaire and the collection of blood and urine samples. Respondent-driven sampling (RDS), a sampling technique for use among hidden populations, was used to recruit the samples.ResultsWhen round 1 is compared with round 2, there was a marked and statistically significant improvement in the use of condoms at last sex with both occasional (35.2% to 72.4%) and regular (25.8% to 57.7%) clients, and an increase in the proportion having ever had an HIV test (8.9% to 29.1%). There was no evidence of an improvement in the proportional coverage of the HIV prevention services delivered to FSWs in Dimapur between round 1 and round 2. In round 2, FSWs exposed to the programme were more than twice (OR=2.27) as likely to consistently use condoms with occasional clients, four times (OR: 4.11) more likely to use condoms consistently with regular clients and nine times (OR: 9.08) more likely to have ever had an HIV test.ConclusionsWe found evidence of an increase in condom use and HIV testing, and a strong and consistent association between programme exposure and condom use and HIV testing indicating that NGO HIV prevention programmes have been making a substantial contribution to HIV prevention among FSWs in Dimapur. However, there was no evidence of improved coverage of HIV prevention services, and there is a clear need to expand the reach of services in order for them to have an impact on a larger pool of FSWs.

BACKGROUND HIV among people who inject drugs (PWID) is a major public health challenge in India. This paper examines PWID in Delhi who also have male-to-male sex with a focus on overlapping HIV risk behaviours and the psychosocial correlates of a history of male-to-male anal sex. METHODS We analysed data collected in April-May of 2012 from a community-based sample of 420 male PWID in Delhi obtained using time location sampling. RESULTS One third (37%) of the men reported a history of anal sex with men, among whom just 16% used a condom at last anal sex. Almost all (93%) participants who had a history of anal sex with men also had sex with women. Chi-square tests revealed that a history of anal sex with men was associated with a higher number of female sexual partners and sharing of needles and syringes. Additionally, unprotected sex at last sex with a male partner was significantly associated with unprotected sex at last sex with regular and paid female partners. Multivariate binary logistic regression revealed that the psychosocial correlates of a history of anal sex with other men were: being aged 18-24 (OR = 2.4, p = 0.014), illiteracy (OR = 1.9, p = 0.033), having never been married (OR = 2.6, p = 0.007), a main source of income of crime/begging (OR = 3.1, p = 0.019), a duration of injecting drug use greater than 20 years (OR = 3.4, p = 0.035) and suicidal ideation (OR = 1.7, p = 0.048). CONCLUSION Male-to-male sex was associated with psychosocial vulnerability, including a longer history of injecting drug use, suicidal ideation and socio-economic disadvantage. Given the extent of overlapping HIV risk behaviours, HIV programs for PWID would benefit from a strong focus on prevention of sexual HIV transmission, especially among male injectors who also have sex with other men.

Undiagnosed HIV among people who inject drugs in Manipur, India

Gregory Armstrong; Gajendra Kumar Medhi; Jagadish Mahanta; Ramesh Paranjape; Michelle Kermode

Manipur is a geographically isolated state of India characterised by a high HIV prevalence among people who inject drugs (PWID). A low-to-moderate lifetime rate of HIV testing has been documented amongst PWID in Manipur. Little is known about the extent of undiagnosed HIV in this setting and whether uptake of HIV testing (and knowledge of a positive diagnosis) leads HIV-positive PWID to change their risk behaviours. The cross-sectional data (n = 821) analysed for this paper were collected in 2009 for the Integrated Behavioural and Biological Assessment (IBBA) using interviewer-administered questionnaires and the collection of de-linked blood and urine samples. Almost one-third (30.7%) of the participants tested HIV positive. The majority knew where to obtain a confidential HIV test (80.7%), however, half of the HIV-positive participants had either never had an HIV test (37.7%), or had undertaken a test without collecting the result (12.7%). Almost one-quarter (23.4%) of the HIV-positive participants and 17.4% of the HIV-negative participants had shared a needle/syringe with at least one other injector during the preceding month. Encouragingly, HIV-positive participants were significantly more likely than HIV-negative participants to use condoms with their regular sexual partners, however, there was still a high proportion of HIV-positive participants who did not use a condom at last sex with their regular (47.2%) or casual (48.0%) partners. Having taken an HIV test and collected the result was associated with a reduction in HIV-risk behaviours among HIV-positive participants, but not among HIV-negative participants. In conclusion, we found that a substantial proportion of the HIV-positive PWID in Manipur were not aware of their positive status, and risky injecting and sexual practices were commonplace. However, HIV-positive PWID appear to reduce their high-risk behaviours when they become aware of their HIV status highlighting the importance of taking HIV testing coverage to scale.

Gregory Armstrong; Jane Pirkis; Kerry Arabena; Dianne Currier; Matthew J. Spittal; Anthony F. Jorm

Objectives: We compare the prevalence of suicidal thoughts and attempts between Indigenous and non-Indigenous males in urban and regional Australia, and examine the extent to which any disparity between Indigenous and non-Indigenous males varies across age groups. Methods: We used data from the baseline wave of The Australian Longitudinal Study on Male Health (Ten to Men), a large-scale cohort study of Australian males aged 10–55 years residing in urban and regional areas. Indigenous identification was determined through participants self-reporting as Aboriginal, Torres Strait Islander or both. The survey collected data on suicidal thoughts in the preceding 2 weeks and lifetime suicide attempts. Results: A total of 432 participants (2.7%) identified as Indigenous and 15,425 as non-Indigenous (97.3%). Indigenous males were twice as likely as non-Indigenous males to report recent suicidal thoughts (17.6% vs 9.4%; odds ratio = 2.1, p < 0.001) and more than three times as likely to report a suicide attempt in their lifetime (17.0% vs 5.1%; odds ratio = 3.6; p < 0.001). The prevalence of recent suicidal thoughts did not differ between Indigenous and non-Indigenous males in younger age groups, but a significant gap emerged among men aged 30–39 years and was largest among men aged 40–55 years. Similarly, the prevalence of lifetime suicide attempts did not differ between Indigenous and non-Indigenous males in the 14- to 17-years age group, but a disparity emerged in the 18- to 24-years age group and was even larger among males aged 25 years and older. Conclusion: Our paper presents unique data on suicidal thoughts and attempts among a broad age range of Indigenous and non-Indigenous males. The disparity in the prevalence of suicidal thoughts increased across age groups, which is in contrast to the large disparity between the Indigenous and non-Indigenous suicide rates in younger age groups.

BackgroundHuman immunodeficiency virus (HIV) infection is a significant problem among female sex workers (FSWs) in Nagaland, India. Place of solicitation and sex vary considerably in this context. The aim of this study was to investigate the relationship between categories of sex work and HIV risks.MethodsIn 2009 a survey was undertaken among 417 FSWs in Dimapur, Nagaland using an interviewer-administered questionnaire and blood and urine samples. Using this data, we constructed a typology of sex work by combining usual place of solicitation and place of sex, and examined variations in demographics, sex work patterns, sexually transmitted infections (STIs) and HIV prevalence across typology categories. Binary logistic regression analyses were done to examine the association between category of sex work and HIV, STIs, and condom use.ResultsBy combining place of solicitation with place of sex, seven distinct categories of sex work emerged. The largest category were women who usually solicited in a public place and had sex in a rented room or lodge (31.7%, n = 132). One-tenth of participants were HIV positive (10.3%) and 35.4% had at least one STI (reactive syphilis serology, gonorrhoea or chlamydia). FSWs who both solicited and entertained in a rented room or lodge (OR = 13.3; 95% CI 2.2, 81.5) and those who solicited by phone and had sex in a rented room or lodge (OR = 6.3; 95% CI 1.0, 38.0) were more likely to be HIV positive compared to home-based FSWs. Women who both solicited and entertained in public (OR = 6.7; 95% CI 1.6, 28.0) and who solicited in public and entertained in a rented room or lodge (OR = 2.5; 95% CI 1.1, 6.0) were more likely to test positive for an STI compared to home-based FSWs.ConclusionThe results indicate that different categories of sex work are associated with different HIV and STI risk profiles. Local contextual understanding of the different types of sex work and the associated levels of risk assist NGOs to target their interventions more effectively and efficiently in order to reduce STI and HIV prevalence among FSWs and their clients.
