    • Amplified disparities: The association between spousal education and own health 

      Lamu, Admassu Nadew; Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-11)
      Positive associations between own educational attainment and own health have been extensively documented. Studies have also shown spousal educational attainment to be associated with own health. This paper investigates the extent to which spousal education contributes to the social gradient in health, net of own education; and whether parts of a seeming spousal education effect are attributable to ...

    • Are relative educational inequalities in multiple health behaviors widening? A longitudinal study of middle-aged adults in Northern Norway 

      Ibarra Sanchez, Ana Silvia; Chen, Gang; Wisløff, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-22)
      Introduction: Educational inequality in multiple health behaviors is rarely monitored using data from the same individuals as they age. The aim of this study is to research changes in relative educational inequality in multiple variables related to health behavior (smoking, physical activity, alcohol intake, and body mass index), separately and collectively (healthy lifestyle), among middle-aged adults ...

    • Assessment of outcome measures for cost–utility analysis in depression: mapping depression scales onto the EQ-5D-5L 

      Gamst-Klaussen, Thor; Lamu, Admassu N.; Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-13)
      <i>Background:</i> Many clinical studies including mental health interventions do not use a health state utility instrument, which is essential for producing quality-adjusted life years. In the absence of such utility instrument, mapping algorithms can be applied to estimate utilities from a disease-specific instrument.<p> <p><i>Aims:</i> We aim to develop mapping algorithms from two widely used ...

    • Combining education and income into a socioeconomic position score for use in studies of health inequalities 

      Lindberg, Marie Hella; Chen, Gang; Olsen, Jan Abel; Abelsen, Birgit (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-13)
      Background: In studies of social inequalities in health, there is no consensus on the best measure of socioeconomic position (SEP). Moreover, subjective indicators are increasingly used to measure SEP. The aim of this paper was to develop a composite score for SEP based on weighted combinations of education and income in estimating subjective SEP, and examine how this score performs in predicting ...

    • Do country-specific preference weights matter in the choice of mapping algorithms? The case of mapping the Diabetes-39 onto eight country-specific EQ-5D-5L value sets 

      Lamu, Admassu Nadew; Chen, Gang; Gamst-Klaussen, Thor; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      <p><i>Purpose</i>: To develop mapping algorithms that transform Diabetes-39 (D-39) scores onto EQ-5D-5L utility values for each of eight recently published country-specific EQ-5D-5L value sets, and to compare mapping functions across the EQ-5D-5L value sets.</p> <p><i>Methods</i>: Data include 924 individuals with self-reported diabetes from six countries. The D-39 dimensions, age and gender ...

    • Educational patterns of health behaviors and body mass index: A longitudinal multiple correspondence analysis of a middle-aged general population, 2007-2016 

      Ibarra Sanchez, Ana Silvia; Abelsen, Birgit; Chen, Gang; Wisløff, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-01)
      Social differences in body mass index and health behaviors are a major public health challenge. The uneven distribution of unhealthy body mass index and of unhealthy behaviors such as smoking, physical inactivity, and harmful alcohol consumption has been shown to mediate social inequalities in chronic diseases. While differential exposures to these health variables have been investigated, the ...

    • Explaining subjective social status in two countries: The relative importance of education, occupation, income and childhood circumstances 

      Lindberg, Marie Hella; Chen, Gang; Olsen, Jan Abel; Abelsen, Birgit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-03)
      In the literature on social inequalities in health, subjective socioeconomic position (SEP) is increasingly applied as a determinant of health, motivated by the hypothesis that having a high subjective SEP is health-enhancing. However, the relative importance of determinants of subjective SEP is not well understood. Objective SEP indicators, such as education, occupation and income, are assumed to ...

    • Extending the EQ-5D: the case for a complementary set of 4 psycho-social dimensions 

      Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-20)
      Objectives - The EQ-5D is the most widely applied preference-based health-related quality of life measure. However, concerns have been raised that the existing dimensional structure lacks sufficient components of mental and social aspects of health. This study empirically explored the performance of a coherent set of four psycho-social bolt-ons: Vitality; Sleep; Personal relationships; and Social ...

    • Filling the psycho-social gap in the EQ-5D: the empirical support for four bolt-on dimensions 

      Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)
      <i>Purpose</i> - The EQ-5D is the most widely applied generic preference-based measure (GPBM) of health-related quality of life (HRQoL). Much concern has been raised that its descriptive system is lacking psycho-social dimensions. A recent paper in this journal provided theoretical support for four dimensions to fill this gap. The current paper aims to provide empirical support for these suggested ...

    • Health state utility instruments compared: inquiring into nonlinearity across EQ-5D-5L, SF-6D, HUI-3 and 15D 

      Gamst-Klaussen, Thor; Chen, Gang; Lamu, Admassu Nadew; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-21)
      Purpose Different health state utility (HSU) instruments produce different utilities for the same individuals, thereby compromising the intended comparability of economic evaluations of health care interventions. When developing crosswalks, previous studies have indicated nonlinear relationships. This paper inquires into the degree of nonlinearity across the four most widely used HSU-instruments ...

    • How is your life? understanding the relative importance of life domains amongst older adults, and their associations with self-perceived COVID-19 impacts 

      Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-06)
      Purpose - This study aims to provide new knowledge on the relative importance of key life domains amongst older adults, and how the Coronavirus pandemic has influenced their life (domain) satisfaction.<p> <p>Methods - A cross-sectional survey was administrated to an online panel of the general public aged 65 years and older in Australia from 28 April to 26 May 2020. Life satisfaction was measured ...

    • The relative importance of education and health behaviour for health and wellbeing 

      Olsen, Jan Abel; Chen, Gang; Lamu, Admassu Nadew (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-11)
      Background - Indicators of socioeconomic position (SEP) and health behaviours (HB) are widely used predictors of health variations. Their relative importance is hard to establish, because HB takes a mediating role in the link between SEP and health. We aim to provide new knowledge on how SEP and HB are related to health and wellbeing.<p> <p>Methods - The analysis considered 14,713 Norwegians aged ...
