LABOR MARKET EFFECTS OF INSULIN DEPENDENT AND NON-INSULIN DEPENDENT DIABETES AMONG CANADIAN LABOR FORCE

Farah Farahati, PhD, McMaster university, Epidemiology and Biostatistics, hamilton, ON, Canada

Objective: Many labor market analyses have established significant negative impact of diabetes in labor market behavior. This study investigates the impact of diabetes on the probability of working and weekly working hours for Canadian with insulin dependent diabetes (IDDM) and non-insulin dependent diabetes (NIDDM) and diabetes related comorbidities/complications, compared with healthy groups.

Methods: Two-part model were performed to predict the weekly working hours (after adjusting for other chronic disorders and socio-demographic) of diabetics among respondent to the Canadian Community Health Survey 2001. Logistics regression and multiple OLS analyses were used to predict the probability of working and weekly work hours. Sampling weights were used to be representative of the Canadian population.

Results: Women and men with IDDM had lower probability of having job by 10% and 5%, respectively compared with healthy groups. These probabilities were even less for women and men with diabetes related comorbidities/complications by 13% and 5% compared with IDDM without diabetes reated comorbidities/complications. The probability of working for women and men with NIDDM also were 7% and 2% less than women and men without this disorder. Similarly, these probabilities were even less for women and men with NIDDM related comorbidities/complications by 2% compared with those without diabetes reated comorbidities/complications (all at p-values < 0.05). The predicted weekly work hours for women and men without diabetes were 29 and 41 hours, with IDDM were 18 and 30, with IDDM and comorbidities/complications were 13 and 23, with NIDDM were 21 and 35 hours and finally with NIDDM and related comorbidities/complications were 17 and 30, respectively. Conclusions: This is the first study to estimate the impact of diabetes on Labour market outcomes among Canadian Labour force. The effect of diabetes and its related comorbidities on the probability of unemployment and predicted weekly work hours for both men and women in Canada are substantial. The results of this study have implications for cost-effectiveness of diabetes control and may facilitate studies of the health burden of diabetes for the prevention and treatment of diabetes and thus increase the labor productivity.
