The Claim
Overweight Korean women who perform shift work have nearly 80% higher odds of elevated insulin resistance compared to overweight Korean women who work day shifts, with an odds ratio of 1.79, indicating an interaction between excess body weight and non-daytime work schedules that amplifies metabolic risk.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Korean women who are overweight and work nights or rotating shifts are much more likely to have high insulin levels than overweight women who work regular daytime hours, which might mean their bodies have a harder time managing blood sugar.
See the scientific wording
Overweight Korean women who perform shift work have nearly 80% higher odds of elevated insulin resistance than overweight day workers (OR = 1.79), suggesting that excess body weight and non-daytime work schedules interact to amplify metabolic risk.
What the research says
1 studyStudy: Association between shift work and insulin resistance in women: Implications for metabolic health
The study found that women who work nights or irregular shifts are more likely to have insulin resistance, especially if they are overweight — which matches the claim that being overweight and working shifts together makes metabolic problems worse.
