High risk occupations for non-Hodgkin’s lymphoma in New Zealand: case-control study

A recent article by A ’t Mannetje in OEM concludes that crop farmers and meat workers remain high risk occupations for non-Hodgkin’s lymphoma (NHL) in New Zealand, and has identified several other occupations and industries of high NHL.

An elevated NHL risk was observed for field crop and vegetable growers (OR 2.74, 95% CI 1.04 to 7.25) and horticulture and fruit growing (OR 2.28, 95% CI 1.37 to 3.79), particularly for women (OR 3.44, 95% CI 0.62 to 18.9; OR 3.15, 95% CI 1.50 to 6.61). Sheep and dairy farming was not associated with an increased risk of NHL.

Meat processors had an elevated risk (OR 1.97, 95% CI 0.97 to 3.97), as did heavy truck drivers (OR 1.98, 95% CI 0.92 to 4.24), workers employed in metal product manufacturing (OR 1.92, 95% CI 1.12 to 3.28 ) and cleaners (OR 2.11, 95% CI 1.21 to 3.65).

After semi-Bayes adjustment the elevated risks for horticulture and fruit growing, metal product manufacturing and cleaners remained statistically significant, representing the most robust findings of this study.
