Investigation of work-related acute pesticide poisoning among farmers in Jiangsu Province and the risk factors

Abstract

To determine the incidence of work-related acute pesticide poisoning among farmers in Jiangsu Province and to identify the risk factors. Multi-stage stratified sampling and cluster sampling methods were used to randomly select 1490 farmers from the south (Z village), centre (Y village) and north (X village) of Jiangsu Province. The database was established by EpiData 3.1. SPSS 17.0 and SAS 9.13 were used to do chi-square test, trend chi-square test, single factor and multi-factor logistic regression analysis. Among 1490 farmers, 121 people had work-related acute pesticide poisoning in the past year. The incidence rate in Jiangsu Province was 8.1%. 118 farmers (97.5%) were mild pesticide poisoning.3 farmers (2.5%) were moderate pesticide poisoning. The incidence rate of Work-related acute pesticide poisoning in X village of North Jiangsu Province (13.5%, 68/505) is obviously higher than that in Y village of Central Jiangsu Province (4.8%, 19/399) and Z village of South Jiangsu Province (5.8%, 34/586), and the difference is statistically significant (χ(2) = 29.60, P < 0.01). The incidence rate of Work-related acute pesticide poisoning in female (10.4%, 58/557) is obviously higher than that in male (6.8%, 63/933), and the difference is statistically significant (χ(2) = 6.26, P < 0.05). There are lack of safety guidance, unsafety application methods (without alternate row spraying, without backward application, without down-wind application) and risk behaviors in the spraying (without read labels, preparing pesticides without gloves, wiping sweat with hand (s), equipment leakage, body pollution by pesticide, working when feeling sick, without bath after work). If farmers have risk behaviors above, the incidence rate of Work-related acute pesticide poisoning will be obviously higher than farmers who receive safety guidance and have no such dangerous behaviors, and all the differences are statistically significant (P < 0.05). The group of 24 ∼ 34 years old has the highest risk of work-related acute pesticide poisoning (OR = 7.15). The incidence rate of work-related acute pesticide poisoning among farmers in Jiangsu Province was higher. Effective measures are needed to prevent and reduce the occurrence of work-related acute pesticide poisoning. We can teach the farmers who spray pesticides about safety guidance, safety application methods and avoiding risky behaviors.
