Background/aims This study aimed to investigate the relationship between employment status and insulin resistance in the Korean elderly population. Methods The study included 2325 healthy participants (862 men and 1463 women) who did not have diabetes, were60–74 years old, and participated in the 2007–2010 Korea National Health and Nutrition Examination Survey. Their employment status was categorized as employed or unemployed. The homeostasis model assessment of insulin resistance (HOMAIR)was used to assess insulin sensitivity. Insulin resistance was defined as values greater than the 75th percentile of the HOMA-IR (> 2.67 in men and > 2.87 in women).Results Mean HOMA-IR values were significantly higher for both sexes in the unemployed group than in the employed group. Compared with the unemployed group, the odds ratios (95% confidence intervals) for insulin resistance in the employed group were 0.55 (0.34–0.87) in men and 0.68 (0.47–0.98) in women after adjusting for confounders. Conclusions Being employed was significantly associated with a lower risk of insulin resistance in the Korean elderly population. These findings suggest that insulin sensitivity could be increased by increasing physical activity through occupational activities in the elderly population.
