Introduction and Purpose Farmers are particularly at high risk of pesticide exposure due to added risk from occupational exposure. The aim of this study is to evaluate knowledge level of farmers in the Çukurova region of the effects of pesticides, toxic symptoms, and protective equipment as well as assessing their attitudes and practices regarding pesticides. Material and Method A total of 420 seasonal agricultural workers in Karataş District of Adana Province, Turkey, were included in the study. The questionnaire form consisting of 3 sections was administered using face-to-face interview method. Results The mean age of the participants was 40.2 ± 10.6 years. They were engaged in farming for a mean duration of 18.5 ± 10.6 years. All of them used pesticides, but none of them had been trained on the use of pesticides. Only 26.2% of them stored pesticides in a private depot. The farmers who took empty pesticide containers to special collection bins or centers constituted only 4.3% of them. While 84.0% of them thought that pesticides could have a negative impact on human health, 5.0% of them had experienced a medical problem and 1.0% of them were poisoned after applying pesticides. Conclusion The results show that knowledge level of farmers of safe use of pesticides is very inadequate. This lack of knowledge adversely affects workers' quality of life as well as occupational health and safety. Appropriate training programs should be organized to increase their level of knowledge.

Introduction Vitamin D deficiency is a common problem, and it is related to increased risk of obesity, metabolic syndrome, atherosclerosis, and cardiovascular disease. Vitamin D has a beneficial effect on dyslipidemia and insulin secretion. We aimed to investigate the impact of vitamin D 3 supplementation on anthropometric and laboratory parameters in overweight and obese premenopausal women. Material and methods Seventy-two overweight and 50 obese vitamin-D-deficient premenopausal women (mean age: 43.1 ±10.4 years) were included in the study. Baseline mean 25-hydroxyvitamin D [25(OH)D] level was 6.1 (min.–max. = 2.9–15.8) ng/ml in overweight and was 5.6 (min.–max. = 3.0–22.0) ng/ml in obese subjects. At baseline and at the sixth month of supplementation, serum 25(OH)D, intact parathormone (iPTH), calcium, phosphorus, homeostasis model assessment of insulin resistance (HOMA-IR), and lipid profiles were assessed. Results Following vitamin D 3 supplementation in overweight and obese subjects, serum 25(OH)D increased from 6.1 to 34.7 ng/ml and 5.6 to 34.7 ng/ml, respectively ( p < 0.001). At the sixth month of supplementation in both overweight and obese subjects, a significant reduction was detected in HOMA-IR ( p < 0.001), low-density lipoprotein cholesterol (LDL-C) ( p = 0.046, p = 0.044; respectively) and iPTH levels ( p ≤ 0.001, p < 0.001; respectively). A negative adjusted correlation was found between changes in 25(OH)D and HOMA-IR ( r = –0.581, p < 0.001; r = –0.389, p = 0.005; respectively). A 1 ng/ml increase in serum 25(OH)D level led to a 0.30-fold reduction in HOMA-IR level ( p = 0.002). Conclusions Our results support the effect of vitamin D 3 supplementation in HOMA-IR and LDL-C improvement in both obese and overweight subjects. Further studies focused on low serum 25(OH)D levels with insulin resistance and dyslipidemia are needed.

The findings of the study show that migrant seasonal agricultural workers in Turkey have insufficient working conditions, wages, accommodation facilities, nutrition opportunities, health conditions, and occupational health and safety conditions. This insufficiency negatively affects life qualities of the workers, utilization of health-care services, and their occupational health status and safety.
