RESUMEN
Physical activity (PA) is effective in the prevention of type 2 diabetes mellitus (T2DM). According to the German national treatment guidelines for T2DM, PA is recommended at all stages of the treatment process. Adults with T2DM were recruited within the cross-sectional telephone survey 'Disease knowledge and information needs-Diabetes mellitus (2017)'. Self-reported data on socio-demographic characteristics, previous and current T2DM treatment, and PA behavior were collected. Using multivariable logistic regression models, the correlation between PA treatment (referrals and recommendations) and PA was investigated. Overall, 1149 adults diagnosed with T2DM are included in the analysis. Of the participants, 66.7% reported having ever received PA as part of their T2DM treatment with 61% of the participants reporting PA treatment at the time of the initial T2DM diagnosis and 54% at the time of the interview. Women, older participants, and those with a lower educational level were less likely to have ever been treated with PA. Currently being treated with PA as part of the T2DM treatment was associated with higher rates of achieving the World Health Organization's PA recommendations (≥150 min per week) (OR = 1.95, 95% CI: 1.42-2.68), as well as ever being treated with PA (OR = 1.74, 95% CI: 1.20-2.38). The analyses showed that PA treatment plays a role in the treatment process of T2DM, but not all patient subgroups benefit in the same way. Efforts to increase PA treatment as part of T2DM treatment are needed, especially for those who are currently not treated with PA. Further research is needed to better understand the type of PA (e.g., structured or unstructured) undertaken by adults with T2DM to develop tailored PA interventions for adults with T2DM and for those in vulnerable subgroups.
RESUMEN
BACKGROUND: In Germany, risk of hepatitis C virus (HCV) infection is highest among people who inject drugs (PWID). New injectors (NI) are particularly vulnerable for HCV-acquisition, but little is known about health seeking behaviour and opportunities for intervention in this group. We describe characteristics, HCV prevalence, estimated HCV incidence and awareness of HCV-status among NIs and missed opportunities for hepatitis C testing. METHODS: People who had injected drugs in the last 12 months were recruited into a cross-sectional serobehavioural study using respondent-driven sampling in 8 German cities, 2011-2014. Data on sociodemographic characteristics, previous HCV testing and access to care were collected through questionnaire-based interviews. Capillary blood was tested for HCV. People injecting drugs < 5 years were considered NI. RESULTS: Of 2059 participants with available information on duration of injection drug use, 232 (11% were NI. Estimated HCV incidence among NI was 19.6 infections/100 person years at risk (95% CI 16-24). Thirty-six percent of NI were HCV-positive (thereof 76% with detectable RNA) and 41% of those HCV-positive were unaware of their HCV-status. Overall, 27% of NI reported never having been HCV-tested. Of NI with available information, more than 80% had attended low-threshold drug services in the last 30 days, 24% were released from prison in the last 12 months and medical care was most commonly accessed in hospitals, opioid substitution therapy (OST)-practices, practices without OST and prison hospitals. CONCLUSION: We found high HCV-positivity and low HCV-status awareness among NI, often with missed opportunities for HCV-testing. To increase early diagnosis and facilitate treatment, HCV-testing should be offered in all facilities, where NI can be reached, especially low-threshold drug services and addiction therapy, but also prisons, hospitals and practices without OST.

OBJECTIVES: The aim of this study was to investigate the association between detention experience and hepatitis C virus (HCV) status, the role of duration and frequency of detention, and whether risk behaviours practiced in detention could explain an observed increase in risk. METHODS: Current drug injectors (injecting in the last 12 months) were recruited to participate in a sero-behavioural, cross-sectional survey using respondent-driven sampling in eight German cities during the years 2011-2014. Using multivariable logistic regression, the association between HCV status and reported detention experience was investigated. RESULTS: A total of 1998 participants were included in the analysis. Of these, 19.9% reported no detention experience, 28.6% short and rare experience (≤3.5 years in total, ≤3 times), 12.1% short but frequent experience, 7.1% long but rare experience, and 32.4% long and frequent experience. After correcting for HCV risk factors, the association between detention experience and HCV status remained statistically significant. By adjusting the model for intramural risk behaviours, the odds ratios of detention experience were reduced but remained significant. CONCLUSIONS: The proportion of people who inject drugs positive for HCV increased with both frequency and duration of their detention experience. As intramural risk behaviours could not fully explain this increase, it appears that transfers between community and custody may confer additional risks.

BACKGROUND: High prevalence of drug use and injection-related risk behaviours have been reported among former Soviet Union (FSU)-migrants. To investigate hepatitis C (HCV) and HIV seroprevalence and related risk behaviours in this subgroup in Germany, we compared first generation FSU-migrants and native Germans using data from a sero-behavioural survey of people who inject drugs (PWID). METHODS: Current injectors were recruited using respondent-driven sampling in eight German cities in 2011-2014. Questionnaire-based interviews were conducted and dried blood spots collected and tested for anti-HCV, HCV-RNA, and anti-HIV1/2. Descriptive and multivariable analyses (MVA) were performed. RESULTS: A total of 208 FSU-born and 1318 native German PWID were included in the analysis. FSU-migrants were younger than Germans (median age: 33 vs. 39 years), and more often male (83.1% vs. 75.9%, pâ¯=â¯0.022). HCV seroprevalence was 74.5% in FSU-migrants vs. 64.6% in Germans (pâ¯=â¯0.006), HIV seroprevalence was 5.8% and 4.6%, respectively (pâ¯=â¯0.443). The proportion of FSU-migrants reporting injecting-related risk behaviours was higher than among Germans: injecting daily (39.4% vs. 30.2%, pâ¯=â¯0.015), with friends (39.2% vs. 31.2%, pâ¯=â¯0.038), cocaine (32.7% vs. 23.8%, pâ¯=â¯0.044), more than one drug (18.2% vs. 9.6%, pâ¯=â¯0.006), and sharing filters/cookers (35.5% vs. 28.0%, pâ¯=â¯0.045). No statistically significant differences were observed in HIV/HCV testing rates (range: 50.7%-65.6%), opioid substitution treatment (43.9% vs. 50.5%), and access to clean needles/syringes (89.8% vs. 90.3%). In MVA, risk for HCV-infection was increased in male FSU-migrants compared to German males (OR 3.32, pâ¯=â¯0.006), no difference was identified between female FSU-migrants and German females (OR: 0.83, pâ¯=â¯0.633). CONCLUSION: Male FSU-migrants were at highest risk of being HCV infected. Therefore, targeted actions are needed to ensure access and acceptance of harm reduction measures, including HCV-testing and -treatment for this subpopulation of PWID.

BACKGROUND: People who inject drugs (PWID) are at increased risk of acquiring and transmitting HIV and Hepatitis C (HCV) due to sharing injection paraphernalia and unprotected sex. To generate seroprevalence data on HIV and HCV among PWID and related data on risk behaviour, a multicentre sero- and behavioural survey using respondent driven sampling (RDS) was conducted in eight German cities between 2011 and 2014. We also evaluated the feasibility and effectiveness of RDS for recruiting PWID in the study cities. METHODS: Eligible for participation were people who had injected drugs within the last 12 months, were 16 years or older, and who consumed in one of the study cities. Participants were recruited, using low-threshold drop-in facilities as study sites. Initial seeds were selected to represent various sub-groups of people who inject drugs (PWID). Participants completed a face-to-face interview with a structured questionnaire about socio-demographics, sexual and injecting risk behaviours, as well as the utilisation of health services. Capillary blood samples were collected as dried blood spots and were anonymously tested for serological and molecular markers of HIV and HCV. The results are shown as range of proportions (min. and max. values (%)) in the respective study cities. For evaluation of the sampling method we applied criteria from the STROBE guidelines. RESULTS: Overall, 2,077 PWID were recruited. The range of age medians was 29-41 years, 18.5-35.3 % of participants were female, and 9.2-30.6 % were foreign born. Median time span since first injection were 10-18 years. Injecting during the last 30 days was reported by 76.0-88.4 % of participants. Sharing needle/syringes (last 30 days) ranged between 4.7 and 22.3 %, while sharing unsterile paraphernalia (spoon, filter, water, last 30 days) was reported by 33.0-43.8 %. A majority of participants (72.8-85.8 %) reported incarceration at least once, and 17.8-39.8 % had injected while incarcerated. Between 30.8 and 66.2 % were currently in opioid substitution therapy. Unweighted HIV seroprevalence ranged from 0-9.1 %, HCV from 42.3-75.0 %, and HCV-RNA from 23.1-54.0 %. The implementation of RDS as a recruiting method in cooperation with low-threshold drop in facilities was well accepted by both staff and PWID. We reached our targeted sample size in seven of eight cities. CONCLUSIONS: In the recruited sample of mostly current injectors with a long duration of injecting drug use, seroprevalence for HIV and HCV varied greatly between the city samples. HCV was endemic among participants in all city samples. Our results demonstrate the necessity of intensified prevention strategies for blood-borne infections among PWID in Germany.

BACKGROUND: People who inject drugs (PWID) are disproportionately affected by both HIV and hepatitis C infection (HCV). Awareness of infection status is essential to ensure linkage to appropriate healthcare for those infected, who need treatment and regular follow-up, as well as for uninfected individuals, who need access to targeted testing and counselling services. In this paper we compare self-reported HIV and HCV status with serological markers of infection among PWID recruited through respondent driven sampling. METHODS: From 2011 through 2014, biological and behavioural data was collected from 2,077 PWID in Germany. Dried blood spots from capillary blood samples were collected and screened for HCV antibodies, HCV RNA and HIV-1/-2 antibodies. HIV reactive samples were confirmed by Western blot. RESULTS: Laboratory testing revealed that 5 % were infected with HIV and 81 % were aware of being infected. Chronic HCV infection was detected in 41 % of the participants, 2 % had an acute HCV infection, 22 % had a cleared infection, and 34 % were unexposed to HCV. The concordance between self-reported and measured HCV status was lower than for HIV, with 73 % of those with chronic HCV infection being aware of their infection. CONCLUSIONS: We found a relatively high awareness of HIV and HCV infection status among PWID. Nevertheless, access to appropriate testing, counselling and care services targeted to the needs of PWID should be further improved, particularly concerning HCV. TRIAL REGISTRATION: Ethical approval was received from the ethics committee at the medical university of Charité, Berlin, Germany in May 2011 and with an amendment approved retrospectively on 19/11/2012 (No EA4/036/11). The German Federal Commissioner for Data Protection and Freedom of Information approved the study protocol retrospectively on 29/11/2012 (III-401/008#0035).
RESUMEN
BACKGROUND: People who inject drugs are at high risk for hepatitis B, hepatitis C and HIV. HTLV was reported by neighboring countries to be prevalent in this population, but the situation for Germany is unclear. To generate seroprevalence and related behavioural data and to enhance prevention efforts against these infections for drug users in Germany, a multicentre sero- and behavioural survey was initiated. People who inject drugs are not well reached by services for testing and counselling for blood-borne infections in Germany. An interventional part of the study is intended to prove feasibility and acceptance of testing and counselling in low-threshold drop-in settings. METHODS/DESIGN: Between May 2011 and March 2015, eligible participants (persons having injected drugs within the last 12 months, aged 16 years+, and living in the study city) are recruited by respondent driven sampling, using low-threshold drop-in facilities as study-sites in eight German cities with large drug scenes. Calculated sample size is 2,033 participants. Capillary blood samples collected as dried blood spots are anonymously tested for serological and molecular markers of hepatitis B and C, HIV, and HTLV I and II. A detailed face-to-face-interview about hepatitis- and HIV-related knowledge, former testing, imprisonment, sexual and injecting risk behaviour is conducted with participants. Staff is trained to offer pre- and post-test-counselling of blood-borne infections and HIV rapid testing to participants. DISCUSSION: We chose respondent driven sampling for recruitment of participants to improve representativeness of results. Persons, who are not reached by the facility where the study is conducted, are aimed to be included by recruitment through their personal social network of injecting drug users. To reduce differential biases in the questions on knowledge of transmission and prevention of infections, we present true statements on hepatitis B, C and HIV, their possible routes of transmission and measures of prevention to participants. Participants are told that the statements are true and are asked to answer if they knew this fact already or if it is new to them. In case of knowledge gaps they are offered free targeted counselling as well as free HIV rapid testing and post-test counselling of HIV and hepatitis test results.
