Share of women who had low back pain in the past 3 months U.S. 2016, by age

In three separate questions, respondents were asked, ‘‘During the past 3 months, did you have a severe headache or migraine? ...low back pain? ...neck pain?’’ Respondents were instructed to report pain that had lasted a whole day or more, and not to report fleeting or minor aches or pains. Persons may be represented in more than one column.
Estimates are age-adjusted to the year 2000 standard population using five age groups: 18–44 years, 45–54 years, 55–64 years, 65–74 years, and 75 years and over. Age-adjusted estimates in this table may differ from other age-adjusted estimates based on the same data and presented elsewhere if different age groups are used in the adjustment procedure.
