Prevalence rates and prevalence odds ratios

I need to calculate prevalence rates and prevalence odds ratios for a particular disease, classified as 0/1 in my database. In particular, i have to calculate the prevalence ratios of the disease using different dichotomized variables (i.e. age > or < 70 years etc.).
In addition, i have to calculate sensitivity and specificity, as well as positive or negative predictive values, of a diagnostic test.
Which statistical software should i use to perform such analyses? Anyone could help me, please?
Thank You very much
