Case control study of STI patients and its associated risk factors

Background A sexually transmitted infection (STI), also known as sexually transmitted disease (STD) or venereal disease (VD), is an illness that has a significant probability of transmission between humans by means of human sexual behavior, including vaginal intercourse, oral sex, and anal sex. Methods We performed a hospital-based, case–control study of 50 patients with STI/STD disease and 100 control patients were suffering from either another disease or attendant of patients. Chi-square and Multivariate logistic regression models were used for case–control comparisons. Results There is significant association was observed between the age of subject and study groups [Chi-square= 7.669 and p-value= 0.022]. There is significant association was observed between the gender and study groups [Chi- square=6.528, p-value=0.011].69.3% subjects were married out of which 28.8% belongs to cases and 71.2% belongs to controls. There is significant association was observed between per capita income and study groups [Chi-square=8.997, p-value=0.012]. There is significant association was observed between history of migration and study groups. [Chi-square=9.617, p-value=0.003]. Odds ratio between the STI/STD status and who had history of migration is 3.087 taking who had no history of migration. Odds ratio between the SIT/STD and type of family is 2.279 taking nuclear family. Odds ratio between the STI/STD and who had history of alcohol intake is 17.538. ROC Curve is drawn of total score to screen the STI/STD cases. The sensitivity of the test indicates that 96% of patients with a STI/STD have a positive diagnosis test and the specificity of the test indicates that 73% of patients with no STI/STD have a negative diagnosis test. Positive predictive value and 66% and Negative predictive value 97% along with 82.6% diagnostics accuracy. Conclusions The two most effecting cause of STI/STD are found are History of migration with 78% variation and history of alcohol intake with 31%
