Online support groups were more likely to be used by those with ``fair'' health (OR = 3.28, 95{\%} CI = 1.21, 8.92) and ``poor'' health (OR = 5.98, 95{\%} CI = 1.49, 24.07) and those with lower incomes (OR = 2.64, 95{\%} CI = 1.09, 6.41) and less likely to be used by those with Internet access both at home and work (OR = 0.56, 95{\%} CI = 0.35, 0.90). Those who were age 35-49 (OR = 2.16, 95{\%} CI = 1.43, 3.26), age 50-64 (OR = 2.44, 95{\%} CI = 1.53, 3.89), and age 65-74 (OR = 2.18, 95{\%} CI = 1.30, 3.67) and those who were married (OR = 1.93, 95{\%} CI = 1.13, 3.30) were more likely to purchase medicine or vitamins online. Conclusions: The Internet was most widely used as a health information resource, with less participation in the purchase of medicine and vitamins and in online support groups. Results suggest that modifying survey questions to better capture forms of online support and medications purchased could provide greater understanding of the nature of participation in these activities.
