This week I ran into the following article: Prevalence of diagnosed type 1 and type 2 diabetes among US adults in 2016 and 2017: population based study BMJ 2018; 362 doi: https://doi.org/10.1136/bmj.k1497(Published 04 September 2018) Cite this as: BMJ 2018;362:k1497.In spite of the article being published in the British Medical Journal the source of the data was the NHIS. Like NHANES, the NHIS it is part of the NCHS, which is under the CDC. This is a annual survey of "average" Americans and the questionnaires are handled by the Census Bureau. NCHS compiles statistical information to help guide public health and health policy decisions. Survey has been ongoing since 1960 and the results of the 2017 survey are available for download as several zip files, containing ASCII and CSV files. The questionnaires are organized around Family, Adult and Child. The major health categories are as follows:Physical and mental health statusChronic conditions, including asthma and diabetesAccess to and use of health care servicesHealth insurance coverage and type of coverageHealth-related behaviors, including smoking, alcohol use, and physical activityMeasures of functioning and activity limitationsImmunizationsThese datasets therefore promote research into many socio-behavioral issues. My review of the 2017 dataset shows that it has hundreds of variables on about 26000 subjects. Below is an image that reports compliance with recommended activity levels gleaned from NHIS data
