Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. Inmates with shorter sentences (<100 months) had a non-significant mean decrease in BMI (t = 0.04, p = 0.97), while inmates with longer sentences (≥ 100 months) had a significant mean increase in BMI (t = 2.52, p = 0.02). Independent t-tests comparing the BMI changes by sentence length yielded t = 1.13, p = 0.26 for 1996-1998, and t = 2.06, p = 0.05 for the length of incarceration. Inmate BMIs by age followed the trends experienced by the general public, but BMIs by ethnicity did not.
