As indicated by the ANGELO framework and similar models, various environmental factors influence population levels of physical activity (PA). To date attention has focused on micro-level environment, while evidence macro-level environment remains scarce mostly limited to high-income countries. This study aims investigate whether at are associated with PA among a broader range Data from World Health Survey (WHS) was used analyze 177,035 adults 38 (mostly low middle income) The International...

Abstract People with HIV may be at increased risk for long COVID after acute SARS-CoV-2 infection. We investigated the association between and in two large electronic health record databases. Using data from Patient-Centered Clinical Research Network (PCORnet) National Cohort Collaborative (N3C) 1/1/2018 to 4/30/2024, our analytic sample included individuals aged ≥21 years SARS-CoV-2. All were classified as having or not. estimated adjusted odds ratio (aOR) of by status using logistic...

Background: Poor health is more prevalent in the East of Europe as compared with West. This variation often attributed to Soviet communism. Few studies investigate this discrepancy within young adults who were children during period. We studied by examining variations between world regions general generations (18–65+). The individual and contextual mechanisms that might influence their also investigated. Methods: World Health Survey data analysed on aged 18–34 (n = 91 823) elders 35+ 132...

Background Socioeconomic inequalities in mortality can be explained by different groups of risk factors. However, little is known whether repeated measurement factors provide better explanation socioeconomic health. Our study examines the extent to which relative educational and income might explanatory (behavioral, psychosocial, biomedical employment) measured at two points time, as compared one baseline.

Responsiveness is a dimension of health system functioning and might be dependent upon contextual factors related to politics. Given this, we performed cross-national comparisons with the aim investigating: 1) associations political patients’ reports responsiveness 2) extent which input output explain these associations. World Health Survey data were analyzed for 44 countries (n = 103 541). Main outcomes included, respectively, 8 7 domains inpatient outpatient care. Linear multilevel...
