A cоmmunity heаlth nurse is cоnducting reseаrch tо compаre the likelihood of developing skin cancer between two groups of adults, based on their exposure to a specific chemical found in cosmetics. Group A consists of 920 adults who do not use cosmetics containing the chemical. Group B consists of 310 adults who do use cosmetics containing the chemical. Over a 25-year period, 292 individuals in Group A and 18 individuals in Group B are diagnosed with skin cancer. The community health nurse would report that Group A is times more likely to develop skin cancer if they use the cosmetics compared to those who do in Group B. Incidence Rate = Number of New Cases in a Given Time Period / Total Population at Risk During That Period Attributable Risk = Incidence in Exposed Group – Incidence in Unexposed Group Relative Risk = RR= Incidence in Exposed Group / Incidence in Unexposed Group Protective Factor = 1 – [Incidence in Exposed Group / Incidence in Unexposed Group] Sensitivity=True Positives / True Positives (TP)+False Negatives (FN) Specificity=True Negatives / True Negatives (TN)+False Positives (FP) OR = (Exposed with disease × Unexposed without disease) / (Exposed without disease × Unexposed with disease)
