The results of the analysis of numerous studies all support the working hypothesis. This means that the use of DDT is much more risky and hazardous to health to justify its use as a malaria control agent by IRS. The results of each of the selected articles and reviews will be described in the order of case-control studies, followed by cohorts, then cross-sectional and finally literature reviews. The first study is that of Rignell-Hydbom; et al. examined DDT exposure as a risk factor for type 2 diabetes. The study was carried out in a well-defined cohort of women (n = 6,917) aged 50 to 59 years from southern Suede. The study used 107 cases out of a total of 371 cases. They stored serum samples for at least three years before type 2 diabetes was diagnosed. In order to assess the risk of developing type 2 diabetes with exposure to DDT, the study used conditional logistic regression and also took an odds ratio as a measure of risk with 95% confidence intervals 17 In 107/371 cases, DDT was not associated with an increased risk of developing type 2 diabetes. The study identified a set of cases (n = 39) who were diagnosed more than six years later. their baseline examination, compared to their controlled studies. Women in the highest quartile had an increased risk of developing type 2 diabetes 17. Overall, the average concentration of DDT was 46% higher than that of controls 17. The study resulted in a risk of 5.5 [95% CI 1.2, 25] for DDT. obtained 17. Another study by author Bräuner EV et al. looked at organochlorines in adipose tissue and the risk of non-Hodgkin lymphoma (NHL). 160,725 people aged 50 to 64 were invited to participate in the prospective study Food, Cancer and Health 2.
