The Claim
Shift work is associated with a 30% higher odds of elevated insulin resistance, as measured by the triglyceride-glucose (TyG) index, in working-age Korean women aged 19–64, independent of age, BMI, lifestyle, and socioeconomic factors, suggesting occupational shift schedules may contribute to metabolic risk in this population.
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.
Women in Korea who work non-traditional hours like nights or rotating shifts are 30% more likely to have higher insulin resistance — a sign their body isn’t using sugar properly — even when you account for their weight, diet, and income, which might mean their work schedule is hurting their metabolism.

What the research says
1 studyStudy: Association between shift work and insulin resistance in women: Implications for metabolic health
This study found that women who work non-day shifts (like nights or rotating shifts) are 30% more likely to have higher insulin resistance — a sign of metabolic risk — than women who work regular day hours, even after accounting for things like weight and lifestyle. This matches the claim exactly.
