The types of prescription drugs Americans use vary by age group.
Medicine used to treat asthma was most common among the youngest cohort. For adolescents, between 12 to 19 years old, stimulants to treat attention deficit disorder were most common with about one in 16 adolescents with a prescription.
Both young and middle-aged adults used antidepressants the most frequently in the past 30 days. One in nine adults, 20 to 59 years old, has an antidepressants prescription.
Older adults, aged 60 and above, had the highest share of drug use at 85%. Nearly half of the older population used prescription drugs to combat high cholesterol, while more than one in five use anti-diabetic drugs.
The survey for the period 2015 to 2016 was conducted by the NCHS. The survey team conducted home interviews, and then followed the interviews with physical examinations.
