The International Social Survey Program, ISSP is a continuing annual programme of cross-national collaboration on surveys covering topics important for social science research. It brings together pre-existing social science projects and coordinates research goals, thereby adding a cross-national, cross-cultural perspective to the individual national studies. Since its start in 1985, the attitudes toward a wide range of different subjects have been studied. Some themes have returned through the years, making it possible to compare them over time. The following topics have been discussed: 1985 The Role of Government I 1986 Social Networks I 1987 Social Inequality I 1988 Family and Changing Gender Roles I 1989 Work Orientations I 1990 The Role of Government II 1991 Religion I 1992 Social Inequality II 1993 Environment I 1994 Family and Changing Gender Roles II 1995 National Identity I 1996 The Role of Government III 1997 Work Orientations II 1998 Religion II 1999 Social Inequality III 2000 Environment II 2001 Social Networks II 2002 Family and Changing Gender Roles III 2003 National Identity II 2004 Social Citizenship I 2005 Work Orientations III 2006 Role of Government IV 2007 Leisure and Sports I 2008 Religion III 2009 Social Inequality IV 2010 Environment III 2011 Health 2012 Family, Work and Gender Roles IV 2013 National Identity 2014 Citizenship Purpose: ISSP aims to design and implement internationally comparable attitude surveys. The study in 2015 is focussing on Work orientations.

In a language contact situation with the high status official language Swahili, a main question is if the Ngoni people no longer can express themselves adequately in Ngoni, - that is if the alternation between the two languages is used to fill linguistic gaps and achieving discursive aims, or if it expresses the shaping of identity. In the recordings rural Ngoni farmers voice their ideas about their cultural heritage, with a special focus on attitudes towards Ngoni culture and cultural changes. The recordings deal with value systems, rituals, taboos and traditions, and naming traditions. The data consists of 36 sound recordings in Ngoni with totally 27 informants/participants who are all bilingual in Ngoni and Swahili. The participants live in two villages outside Songea in the Ruvuma Region of Tanzania, Mhepai and Peramiho B. The sound recordings are 9 focus group recordings and 27 interviews with the participants of the focus group discussions. All participants have given their consent. The focus group recordings are totally about 6 hours. The 9 focus groups were: 15 young persons between 15–20 years old (6 boys and 3 girls from Peramiho B and 3 boys and 3 girls from Mhepai), and 12 persons above the age of 60 (3 women and 3 men from Peramiho B and 3 women and 3 men from Mhepai). All focus group recordings are transcribed and translated into Swahili and English. Code switching to Swahili is marked in bold, even in transcriptions and translations. The interviews were conducted in Swahili, sometimes with parts in ngoni, if needed. The English translations of the interviews are found in the data set, as well as the recordings in Swahili. Each participant has additionally been interviewed after the focus group recording. The qualitative interviews with the 27 informants between the ages of 18 and 77 (13 hours of recordings in total) were conducted in Swahili by the researcher and a Tanzanian assistant. The recordings were conducted in August- September 2014. A metadata sheet with anonymised participants is attached. The metadata consists among other of age, sex, educational level and profession. Additionally, information about the participants' bilingualism, as well as their self-estimation of proficiency in Swahili is given. Background information about the area and participants: The Ngoni speaking area is situated between Tanzania’s Mozambican border and Lake Nyasa, around 1000 km from Dar es Salaam. See map. The area is rather isolated with poor roads. The village of Peramiho B is bigger and more urban than Mhepai, which is remote with hardly any vehicles for transport. Although Peramiho B has a more central and urban location, the living conditions in both villages are similar. People have no electricity, except for an occasional solar panel, and people living in the area are typically subsistence farmers growing maize and other crops. The informants were all farmers, except for 6 young people, from Peramiho B (2 motorcyclists transporting people, 2 masons, I technician and 1 nurse). This lifestyle in the villages implies hard work six days a week. People go to their farming plots in the morning and return at sundown. The villages only have some market stalls and outdoor bars where villagers meet to chat and drink local beer.

National SOM 2011 is accordingly the twentyfifth survey in this series. Purpose: The main purpose is to establish time series that enable researchers to analyse how various changes in society affect people's attitudes and behaviour. The SOM Institute also has an online tool for data analysis, where you can work with data from the national SOM surveys directly in your web browser. You can find it at https://som-institutet.se/dataanalys Tue, 02 Apr 2013 00:00:00 GMT https://researchdata.se/en/catalogue/dataset/snd0912-1 https://researchdata.se/en/catalogue/dataset/snd0912-1 University of Gothenburg This dataset includes data from: In order to identify how the evolution of society affects Swedes’ attitudes and behaviour, the SOM Institute started its National SOM study in 1986. National SOM addresses three areas - society, opinions and mass media - and consists of a large number of questions related to politics, society, media and social background, but their areas of focus differ. Every year, the questionnaires are complemented with questions related to current events. Data is collected through postal questionnaires with an option to respond to the survey online, and each survey is conducted under conditions as identical as possible to make the results from the different years comparable. The SOM Institute Cumulative Dataset contains data from the National SOM surveys from 1986. The data contains a selection of questions frequently asked over the years, focusing on time series. A general rule is that questions should have been asked at least four times. The main purpose is to establish time series that enable researchers to analyse how various changes in society affect people's attitudes and behaviour. The dataset has changed somewhat in relation to the codebook, in order to reduce the risk of re-identification. The following changes have been made: Variables removed: kommun, pinc2009, pinc2011, hinc1986, hinc1990, hinc1993, hinc1999, hinc2008, hinc2011, ssyk, occupation1986, Variables added: socialgroup Variables aggregated: lan unionm_open The SOM Institute also has an online tool for data analysis, where you can work with data from the national SOM surveys directly in your web browser.

The former involves all children born 1953 that lived in the Stockholm metropolitan area as of November 1, 1963, while the latter comprises data for the period 1980-2009 on all individuals living in Sweden in 1980 or 1990, and born before 1986. The study comprises data from both surveys and public register records. The core of the project consists of three surveys from The Stockholm Metropolitan study; The School Study (1966), The Family Study (1968), and The Culture and Leisure Time Study (1985). There is also a wide range of register data, for instance delivery records, occupational and income data, welfare recipiency data, health records, mortality data, educational data, and dependency and child welfare committee data. The Stockholm Birth Cohort offers unique opportunities for longitudinal research within various fields such as sociology, public health science, and psychology. So far the datasets have resulted in more than 140 publications which have dealt with, among other things, whether and how childhood circumstances affect later social outcomes in adult life. Purpose: To aim is to create a new tool for life-course studies of health outcomes as well as social outcomes for research in fields such as psychology, public health science, and sociology.

Almquist Western SOM has been conducted yearly since 1992, but was initially limited to residents of Gothenburg and its surrounding municipalities. In 1998, the survey was extended to include the entire Västra Götaland County plus the municipality of Kungsbacka. The purpose of the regional surveys is to enable SOM researchers to study attitudes and behaviour linked to local and regional issues. They emphasise public services and media, although many of the questions are identical with those used in National SOM in order to make the answers comparable both between the regions and with Sweden at large. Purpose: Study attitudes and behaviors that are linked to local and regional issues and phenomena.

Data was collected through six waves between 1988–2014: 1988-1990 (test wave 1); 1993-1995 (test wave 2); 1998-2000 (test wave 3); 2003-2005 (test wave 4); 2008-2010 (test wave 5); 2013-2014 (test wave 6). For each test wave participants completed a thorough physical examination with blood tests of a nurse and a careful examination of a memory tester. There are data collected from approximately 4,700 participants. On each occasion, data for about 2000 variables were collected for each participant, which includes data on demographics, health, illness, medication, social and cognitive factors. The Betula project has received funding for research infrastructures (large databases) from the Swedish Research Council. This means a major effort to make the Betula database available to researchers outside the project through collaborations with researchers within the Betula project. To the Betulas database, genetic data and biological samples are also connected. Purpose: Study how memory functions change during adult life, to identify risk factors for dementia and to identify early preclinical signs of dementia and determine the critical factors of successful aging.

This study started in year 2000 with postal questionnaires to a non-selected female population in Uppsala, Sweden that was responded by 7.051 participants. On a subgroup of 400 women with oversampling of habitual snorers, careful clinical investigations were performed including anthropometric measurements, blood sampling, full-night polysomnography and oral glucose tolerance tests (OGTT). Ten years later, in year 2010, all responders were restudied with postal questionnaires. In addition, all participants who underwent full polysomnogrphy at baseline were invited to a new identical investigation. Beside all measurements that were performed at baseline, also a dynamic spirometry and ultrasound investigations of carotid arteries were performed at the follow-up. Data have also been obtained from national registers on causes of death, diseases, drug prescription and occupational accidents. Important results from this cohort are that the prevalence of obstructive sleep apnea is very common in a female population with 50% fulfilling the criteria of mild obstructive sleep apnea and as many as 6% have severe sleep apnea. The occurrence of sleep apnea is highly age- and BMI-dependent. Also in an otherwise healthy female population there is an association between sleep apnea during the night an insulin sensitivity, the metabolic syndrome and it’s components, inflammatory parameters as well as fasting levels of Type B natriuretic peptide. Purpose: The purpose of this population-based study is to analyze the prevalence of sleep disordered breathing and other sleep disturbances in women and also to investigate long-term consequences of sleep-disordered breathing.

Information is collected by a validated, semi-quantitative, food frequency questionnaire (FFQ). Data collection is done by identical instrument and in the same manner in the two projects. The FFQ has three main sections: portion size indication for staple foods, intake frequencies, and dietary supplements. Some information on dietary and meal regimens is available. In addition to information on intake frequencies of single food items or food groups, estimated energy and nutrient intake. The Section of Biobank and Registry Support (BRS) adminstrates the database. The Västerbotten Intervention Programme (VIP) och the MONICA-study are population based projects studying life habits in the population and to reduce the incidence of cardiometabolic diseases. Detailed information NSDD can be found at the website. https://www.umu.se/brs/provsamlingar-och-register/kostdatabasen/ The dataset growths by approximately 5000 observations per year and the proportion with repeated observations increases. By January 2016, the combined VIP-MONICA diet dataset includes 121,996 unique subjects (equal proportion men and women) with at least one visit and a diet recording. Of these 8.2% are excluded because of incomplete food intake data, extreme (highest and lowest 1%) food Intake levels (FIL), extreme energy intakes (lowest 1% and >5,000 kcal). Nearly 40% have a second 10-year follow up and 7% a third 10-year follow-up. Intakes are reported on a fixed 9-level scale: never, a few times/year, 1-3 times/month, 1 time/week, 2-3 times/week, 4-6 times/week, 1 time/day, 2-3 times/day, ≥4 times/day. Variables in the dataset: 64-84 food items, 65 nutrients including alcohol, 12 on supplements, 3 diet indexes, In addition, some hundred variables on medical status, socio-economy, tobacco use, physical activity, etc. can be linked from VIP and MONICA. Also, blood samples from the participants are stored at Biobanken norr.
