Introduction: Portable spirometers are commonly used in longitudinal epidemiological studies to measure and track the forced expiratory volume in first second (FEV1) and forced vital capacity (FVC). During the course of the study, it may be necessary to replace spirometers with a different model. This raise questions regarding the comparability of measurements from different devices.

Background: The triglyceride glucose (TyG) index is an easily accessible surrogate marker of insulin resistance, an important pathway in the development of type 2 diabetes and cardiovascular diseases. However, the association of the TyG index with cardiovascular diseases and mortality has mainly been investigated in Asia, with few data available from other regions of the world. We assessed the association of insulin resistance (as determined by the TyG index) with mortality and cardiovascular diseases in individuals from five continents at different levels of economic development, living in urban or rural areas.

Importance: High amounts of sitting time are associated with increased risks of cardiovascular disease (CVD) and mortality in high-income countries, but it is unknown whether risks also increase in low- and middle-income countries.

Objective: To investigate the association of sitting time with mortality and major CVD in countries at different economic levels using data from the Prospective Urban Rural Epidemiology study.

Design, Setting, And Participants: This population-based cohort study included participants aged 35 to 70 years recruited from January 1, 2003, and followed up until August 31, 2021, in 21 high-income, middle-income, and low-income countries with a median follow-up of 11.

Article Synopsis
  • The study investigates the relationship between different lipoproteins and apolipoproteins in various stroke types, highlighting inconsistent associations with stroke risk.
  • Results show that higher levels of apoB and LDL-C are linked to an increased risk of ischemic stroke, while apoA1 and HDL-C have opposed effects depending on the stroke type.
  • The findings suggest that specific lipoprotein ratios, particularly apoB/A1, may offer more insight into ischemic stroke risk than traditional measurements.

Article Synopsis
  • Elevated BMI is linked to a higher risk of cardiovascular disease (CVD), but the effects of medications on this risk across different populations are not well understood.
  • A study with over 145,000 participants from various income countries examined the impact of cardiovascular medications on the incidence of CVD and related deaths over 10 years, finding significant differences based on medication use.
  • Results showed that those not on medications had increased risks of CVD with higher BMI, while those on medications had lower risk ratios, indicating that medication can help mitigate some of the CVD risks associated with elevated BMI.

Background: Separate studies suggest that the risks from smoking might vary between high-income (HICs), middle-income (MICs), and low-income (LICs) countries, but this has not yet been systematically examined within a single study using standardised approaches. We examined the variations in risks from smoking across different country income groups and some of their potential reasons.

Methods: We analysed data from 134 909 participants from 21 countries followed up for a median of 11·3 years in the Prospective Urban Rural Epidemiology (PURE) cohort study; 9711 participants with myocardial infarction and 11 362 controls from 52 countries in the INTERHEART case-control study; and 11 580 participants with stroke and 11 331 controls from 32 countries in the INTERSTROKE case-control study.

Background: Final adult height is a useful proxy measure of childhood nutrition and disease burden. Tall stature has been previously associated with decreased risk of all-cause mortality, decreased risk of major cardiovascular events and an increased risk of cancer. However, these associations have primarily been derived from people of European and East Asian backgrounds, and there are sparse data from other regions of the world.
