Diabetes mellitus and employment: is there discrimination in the workplace?

The employment record of 102 diabetic workers (73 men, 29 women), identified in a cross-sectional survey of 5670 middle-aged people in a New Zealand workforce, was studied for evidence of discrimination in the workplace. Compared with 403 matched controls (292 men, 111 women), diabetic workers showed no significant differences in socioeconomic status, educational attainment, or distribution between occupational groups. Similarly, mean duration of current employment (12.3 vs 12.4 years), mean number of jobs in the past 5 years (1.25 vs 1.34 jobs), frequency of sickness absence, and mean number of hours worked each week (43.5 vs 43.3h) did not differ significantly between diabetic and non-diabetic groups. We found no significant differences in work stress, even among those diabetic individuals with poor blood glucose control. There was no convincing evidence across a broad spectrum of industry that diabetic workers did suffer discrimination in the workplace.
