[Factors that influence the diet and eating habits of Chinese immigrant population in Catalonia (Spain)]. / Factores que influyen en la dieta y los hábitos alimentarios de la población inmigrante china en Cataluña.

OBJECTIVE: To characterize the diet and eating habits of adult immigrants of Chinese origin residing in Santa Coloma de Gramenet (Barcelona, Spain), and to identify the factors that influence the changes in diet and eating habits. METHOD: Qualitative study conducted in 2017 through a discussion group with eight adults of Chinese origin (one man and seven women). The information was complemented by five interviews with key informants (three men and two women) and non-participant observation in health promotion workshops aimed at Chinese patients of a health center in Santa Coloma de Gramenet. RESULTS: Chinese adults made three meals a day and tended to snack between meals. Their diet was based on rice, soy and proteins of vegetable origin. Participants rarely consumed milk and milk derivatives but highlighted their consumption of snacks, sugary drinks and pastries, as well as the incorporation of foods, new dishes and cooking techniques from the host country. The Chinese immigrants tried to maintain their diet of origin, however there were various barriers to this, such as the preference of the local diet by the children, work schedules and lack of time. CONCLUSIONS: A tendency towards dietary acculturation is observed among the participants. Health promotion activities aimed at Chinese families are needed to improve aspects of their diet and eating habits, aiming to reduce the consumption of snacks and sugary products.

Tuberculosis, HIV, and viral hepatitis diagnostics in eastern Europe and central Asia: high time for integrated and people-centred services.

Globally, high rates (and in the WHO European region an increasing prevalence) of co-infection with tuberculosis and HIV and HIV and hepatitis C virus exist. In eastern European and central Asian countries, the tuberculosis, HIV, and viral hepatitis programmes, including diagnostic services, are separate vertical structures. In this Personal View, we consider underlying reasons for the poor integration for these diseases, particularly in the WHO European region, and how to address this with an initial focus on diagnostic services. In part, this low integration has reflected different diagnostic development histories, global funding sources, and sample types used for diagnosis (eg, typically sputum for tuberculosis and blood for HIV and hepatitis C). Cooperation between services improved as patients with tuberculosis needed routine testing for HIV and vice versa, but financial, infection control, and logistical barriers remain. Multidisease diagnostic platforms exist, but to be used optimally, appropriate staff training and sensible understanding of different laboratory and infection control risks needs rapid implementation. Technically these ideas are all feasible. Poor coordination between these vertical systems remains unhelpful. There is a need to increase political and operational integration of diagnostic and treatment services and bring them closer to patients.

[Monitoring and evaluation of hiv in catalonia, getting closer to the 90-90-90 objectives]. / Monitorización y evaluación del VIH en Cataluña, cada vez más cerca de los objetivos 90-90-90.

OBJECTIVE: Epidemiological surveillance of HIV infection allows monitoring its incidence as well as possible epidemiological changes, allowing specific interventions to be planned and their impact monitored. The objective of this article is to describe the results of the monitoring and evaluation of the response to the HIV epidemic in Catalonia, based on data included in the Integrated System of Epidemiological Surveillance of AIDS/HIV and Sexually Transmitted Infections of Catalonia (SIVES). METHODS: A descriptive analysis of the data from the different sources of information of the SIVES was performed. The time period was defined based on the availability of data from each of the sources of information included in the analysis. The information was structured according to the conceptual representation of the cascade of HIV care, as described in the World Health Organization consolidated strategic information guidelines for HIV. RESULTS: Of the total of 4,849 new diagnoses notified (2012-2018), 86% were men, of these; the most frequently reported transmission group was men having sex with men with 65%. The trend in the number of new diagnoses decreased in all transmission groups. It is estimated that in 2018 there were 32,429 people living with HIV in Catalonia, of which 89% were diagnosed, of these, 83% were under follow-up in a specialized unit and 78% of them were under treatment. 73% of people in treatment had suppressed the viral load. CONCLUSIONS: SIVES as an integrated system of different sources of strategic information allows monitoring the HIV epidemic in Catalonia and evaluating the response to it, identifying key populations and determinants to acquire HIV, as well as the barriers to which people living with HIV they face to achieve viral suppression.

OBJETIVO: La vigilancia epidemiológica de la infección por el VIH permite monitorizar su incidencia así como eventuales cambios epidemiológicos, permitiendo planificar intervenciones específicas y monitorizar su impacto. El objetivo de este artículo fue describir los resultados de la monitorización y evaluación de la respuesta a la epidemia del VIH en Cataluña, a partir de los datos incluidos en el Sistema Integrado de Vigilancia Epidemiológica del Sida/VIH e Infecciones de transmisión sexual de Cataluña (SIVES). METODOS: Se realizó un análisis descriptivo de los datos de las diferentes fuentes de información del SIVES. El periodo de tiempo se definió a partir de la disponibilidad de los datos de cada una de las fuentes de información incluidas en el análisis. La información se estructuró de acuerdo a la representación conceptual de la cascada de diagnóstico y tratamiento de VIH, tal y como se describe en las directrices de información estratégica consolidada de la Organización Mundial de la Salud para el VIH. RESULTADOS: Del total de 4.849 nuevos diagnósticos notificados (2012-2018), el 86% eran hombres. De estos, el grupo de transmisión informado más frecuente fueron los hombres que tiene sexo con hombres con un 65%. La tendencia del número de nuevos diagnósticos descendió en todos los grupos de transmisión. Se estima que en 2018 había 32.429 personas viviendo con el VIH en Cataluña, de las cuales el 89% estaban diagnosticadas. De estas, el 83% estaban en seguimiento en una unidad especializada, y el 78% de ellas estaban en tratamiento. El 73% de las personas en tratamiento tenían la carga viral suprimida. CONCLUSIONES: El SIVES, como sistema integrado de diferentes fuentes de información estratégica, permite monitorizar la epidemia del VIH en Cataluña y evaluar la respuesta a la misma, identificando poblaciones claves y determinantes para adquirir el VIH, así como las barreras a las que se enfrentan las personas que viven con VIH para lograr a supresión viral.

[Cobatest network: users' characteristics of community-based voluntary,counselling and testing centres in Spain.] / Red COBATEST: Características de los usuarios de los centros comunitarios de diagnóstico y orientación para el VIH en España.

OBJECTIVE: The COBATEST network (European network of community-based voluntary, counselling and testing centers) allows standardized collection of information to monitor HIV testing at these centers. The objective was to describe the performance of the Spanish centers of the COBATEST network and the epidemiological profile of its users, and to analyze the factors associated with having an earlier HIV test. METHODS: Descriptive analysis of the data collected in the 19 Spanish centers that used the common information collection tools during the year 2015. A multivariate logistic regression model was used to identify factors associated with having an earlier test. RESULTS: A total of 6,077 HIV rapid tests were performed and 1.8% were reactive (3.0% MSM, 3.1% SW, 2.3% PWID, 0.6% heterosexual). 82.1% of the reactives were referred to perform a confirmatory test and 94 (97.9%) were HIV positive, of whom 54% were diverted to the health system. 38% said they had never been tested for HIV. Factors associated with having a previous HIV test were: being over 20 years old; being HSH, SW, or PWID; being foreign; having used condoms at the last penetration; having had an STI in the last year; and having been in jail. CONCLUSIONS: The results show the great potential of these services to reach people who have never been tested for HIV. The HIV cases are concentrated in vulnerable groups. It is necessary to improve the linkage of diagnosed people to health care services.

OBJETIVO: La red COBATEST (red europea de centros comunitarios de cribado del VIH) permite la recogida estandarizada de información para monitorizar las pruebas de VIH realizadas en estos centros. El objetivo fue describir el rendimiento de los centros españoles de la red COBATEST y el perfil epidemiológico de sus usuarios, y analizar los factores asociados a tener una prueba de VIH anterior. METODOS: Análisis descriptivo de los datos recogidos en los 19 centros españoles que usaron las herramientas comunes de recogida de información durante el año 2015. Se realizó un modelo multivariado de regresión logística para identificar factores asociados a tener una prueba anterior. RESULTADOS: Se realizaron un total de 6.077 pruebas rápidas de VIH y de éstas un 1,8% fueron reactivas [3,0% HSH (hombres que tienen sexo con hombres); 3,1% TS (trabajadores/as sexuales); 2,3% UDI (usuarios/as de drogas inyectables); 0,6% heterosexuales)]. El 82,1% de los reactivos se realizaron la prueba confirmatoria y 94 (97,9%) fueron diagnosticados de VIH siendo derivados al sistema sanitario el 54%. El 38% afirmó no haberse realizado nunca la prueba del VIH. Los factores asociados a tener una prueba del VIH anterior son: ser mayor de 20 años; ser HSH, TS, o UDI; ser extranjero; haber usado preservativo en la última penetración; haber tenido una ITS en el último año; y haber estado en prisión. CONCLUSIONES: Los resultados muestran el gran potencial de estos servicios para llegar a personas que nunca se han realizado la prueba del VIH. Los casos de VIH se concentran en colectivos vulnerables. Es necesario mejorar la vinculación de las personas diagnosticadas a los servicios sanitarios.

[PELFI Project: Recruitment and Sociodemographic Characteristics of Immigrant and Autochthonous Families from Alicante and Barcelona City Subcohorts]. / Proyecto PELFI: reclutamiento y características sociodemográficas de las familias inmigradas y autóctonas de las sub-cohortes de Alicante y Barcelona.

This study is a part of the multi-centre project "Platform of Longitudinal Studies of Immigrant Families (PELFI)" of the Immigration and Health Subprogram of the CIBER-ESP. It describes the field work and data collection of two sub-cohorts of immigrant and native families, and their main socio-demographic characteristics. Prospective observational cohort study in carried out in Barcelona and Alicante, Spain. The study population is a a non-probabilistic sample of 180 families of Colombian, Ecuadorian and Moroccan origin and 50 families of Spanish origin. We interviewed adults aged 18-65 years and adolescents aged 12-17 years in each family, through two questionnaires (adolescent/adult). The cooperation rate was 82.0% with an average recruitment rate of 1.3 families per day. In total, 250 families have been recruited, 82 from Ecuador, 82 from Colombia, 29 from Morocco and 57 from Spain. A total of 473 adults (59.8% women and 68.5% employed) were surveyed. Immigrant adults have an average of 13 years living in Spain. A total of 304 adolescents (53.9% female, 27.1% born in Spain but with immigrant parents) were surveyed. The combination of non-probabilistic techniques promoted access and improved recruitment speed. This study provides key information for the design and improvement of cohort studies with immigrant families.

[Epidemiology of human inmunodeficiency virus infection: delay in diagnosis]. / Epidemiología de la infección por virus de la inmunodeficiencia humana. Retraso en el diagnóstico.

Epidemiological surveillance of HIV infection has made notably progress over the last decade, improving knowledge of its characteristics and adapting treatment accordingly. On the other hand, the delayed diagnosis of HIV infection is still an important problem to reduce transmission and improve epidemic control both national and internationally. Although the increased availability of new testing technologies over the last ten years, progress, although statistically significant,in reducing late diagnosis in Spain has been, insufficient in terms of public health, meaning that additional efforts should be put in place to review strategies and increase accessibility to tests, population awareness and decrease the lost opportunities for early diagnosis.

[Trends of HIV mother-to-child transmission in Catalonia, Spain, between 1987 and 2003]. / Evolución de la transmisión vertical del VIH en Cataluña durante el período 1987-2003.

BACKGROUND AND OBJECTIVE: To describe and to analyze the evolution of the mother-to-child transmission (MTCT) of the human immunodeficiency virus (HIV), the clinical and epidemiological characteristics and the use of antiretrovirals (ARV) in the HIV infected pregnant women and their new-borns alive between 1987 and 2003 in Catalonia. MATERIAL AND METHOD: The available clinical-epidemiological and treatment data were obtained from 4 reference hospitals that take care of most of the children born to HIV infected mothers in Catalonia. Two of the hospitals had a data base designed to the follow up of their patients, whereas in the other 2 data were gathered by reviewing clinical registries. For the analysis, 3 periods, based on the recommendations of treatment ARV during pregnancy, were settled down: 1987-1993; 1994-1996, and 1997-2003. RESULTS: 1,105 mother-infant pairs were studied. HIV MTCT was reduced from 20.4% to 3.5% from first to third period of study (p < 0.001). The median age of the mothers increased from 24.6 to 30.5 years of age (p < 0.001). The proportion of women infected by sexual transmission increased from 17.2% to 58.8% (p < 0.001), whereas that of parenteral transmission decreased from the 79.2% to 43.5% (p < 0.001). In the last period, 74.1% of mother-child pairs received complete ARV prophylaxis regimens and 21.6% partial ones. The rate of elective caesarean-section went up from 32.2% to 58.2% (p < 0.001). CONCLUSIONS: The rates of MTCT in our setting have followed the same trend as in other countries of our surroundings. The observed changes reflect the variations in the characteristics of the epidemic in the general population. The implementation of the recommendations on ARV prophylaxis has begun early and it has extended progressively without getting to be total. Additional strategies for the universal coverage of the screening test during pregnancy are still needed.

[Non-occupational post-exposure HIV prophylaxis. Knowledge and practices among physicians and groups with risk behavior]. / Profilaxis postexposición al virus de la inmunodeficiencia humana no ocupacional. Conocimientos y prácticas de profesionales y grupos con conductas de riesgo.

BACKGROUND AND OBJECTIVE: Although occupational post-exposure HIV prophylaxis is widely admitted and used, the non-occupational post-exposure prophylaxis (NONOPEP) is controversial. Prevention of mother-to-child HIV transmission, experimental studies in animal models and retrospective studies in health workers, along with biological plausibility, would justify the use of NONOPEP in certain circumstances. Our objectives were: 1) To review the existence of recommendations; 2) To describe the attitudes, knowledge and practices of the professionals involved in the attention of non-occupational exposures to HIV; 3) To describe the attitudes and knowledge on such a prophylaxis by people with risk behaviours (homosexual men and intravenous drug users (IDU)); and 4) To describe the NONOPEP-related responses of telephone services of public attention on AIDS. SUBJECTS AND METHOD: Descriptive study by means of a survey of each defined target population between September 1999 and July 2000, using self-administered questionnaires and personal interviews. Structured and simulated interviews were used to survey the telephone services. RESULTS: To date, no official recommendations exist. 84% (97/116) of consulted doctors have taken care of some of non-occupational accidental exposure to HIV over the last six months. 77% (75/97) have prescribed NONOPEP, and 76% of doctors prescribing NONOPEP (57/75) have used the 1998 CDC recommendations for occupational exposures. Most frequent observed cases were related to needle sticks in the street and preservative breakage. The assessment of certain risk factors and therapeutic performance in cases of intermediate risk showed discrepancies among doctors. 41% (103/252) among homosexuals and 2% (3/160) among IDU on treatment know the NONOPEP. 15% (15/98) and 98% (70/118) respectively would take less prevention to avoid HIV infection if they took the NONOPEP. It was mentioned the possibility of NONOPEP in 20% (12/59) of calls to the information telephone services on AIDS. CONCLUSIONS: HIV risk accidents susceptible of NONOPEP are relatively frequent. Without forgetting the greater importance of primary prevention, it is advisable to reach and agreement on homogeneous recommendations. It is also advisable to draw up a surveillance system to evaluate the application and eventually the effectiveness of these recommendations.
