mtl

The data are from a convenience sample of 25 women and 10 men who weremiddle-aged or older. The purpose of the study was to understand therelationship between sedentary behavior and thickness of the medial temporallobe (MTL) in the brain.

Variables

  • subject - ID for the individual.
  • sex - Gender, which takes values F (female) or M (male).
  • ethnic - Ethnicity, simplified to Caucasian and Other.
  • educ - Years of educational.
  • e4grp - APOE-4 status, taking a value of E4 or Non-E4.
  • age - Age, in years.
  • mmse - Score from the Mini-Mental State Examination, which is a global cognitition evaluation.
  • ham_d - Score on the Hamilton Rating Scale for depression.
  • ham_a - Score on the Hamilton Rating Scale for anxiety.
  • dig_sym - We (the authors of this R package) are unsure as to the meaning of this variable.
  • delay_vp - We (the authors of this R package) are unsure as to the meaning of this variable.
  • bfr_selective_reminding_delayed - We (the authors of this R package) are unsure as to the meaning of this variable.
  • sitting - Self-reported time sitting per day, averaged to the nearest hour.
  • met_minwk - Metabolic equivalent units score (activity level). A score of 0 means "no activity" while 3000 is considered "high activity".
  • ipaq_grp - Classification of METminwk into Low or High.
  • aca1 - Thickness of the CA1 subregion of the MTL.
  • aca23dg - Thickness of the CA23DG subregion of the MTL.
  • ae_cort - Thickness of a subregion of the MTL.
  • a_fusi_cort - Thickness of the fusiform gyrus subregion of the MTL.
  • a_ph_cort - Thickness of the perirhinal cortex subregion of the MTL.
  • a_pe_cort - Thickness of the entorhinal cortex subregion of the MTL.
  • asubic - Thickness of the subiculum subregion of the MTL.
  • total - Total MTL thickness.
