Body roundness index and the risk of hypertension: a prospective cohort study in Southwest China.

Background: Body roundness index (BRI) is an anthropometric measure related to obesity, combining waist circumference (WC) and height to more accurately reflect body fat. This study aims to investigate the relationship between BRI and the risk of hypertension using data from a prospective cohort study in Southwest China.

Methods: Data for the study were derived from Guizhou Population Health Cohort Study (GPHCS), established in 2010.

Long-term exposure to low-level ozone and the risk of hypertension: A prospective cohort study conducted in a low-pollution region of southwestern China.

Background: The current evidence regarding the association between long-term exposure to ozone (O) and hypertension incidence is limited and inconclusive, particularly at low O concentrations. Therefore, our research aims to investigate the potential link between long-term O exposure and hypertension in a region with low pollution levels.

Methods: From 2010 to 2012, we conducted a cohort prospective study by recruiting nearly 10,000 attendees through multistage cluster random sampling in Guizhou Province, China.

Visual motion sensitivity as an indicator of diabetic retinopathy in type 2 diabetes mellitus.

Objectives: This current study is based on a set of visual motion sensitivity tests, investigating the correlation between visual motion sensitivity and diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM), thereby furnishing a scientific rationale for preventing and controlling DR.

Methods: This research was conducted by a combination of questionnaire collection and on-site investigation that involved 542 T2DM recruited from a community. The visual motion sensitivity determined the visual motion perception of the participants across three spatial frequencies (low, medium, and high) for both the first- and second-order contrast.
