註釋Incarcerated females are an under-studied population with little published research on weight changes or obesity. A sample of 98 female inmates, at a Federal Bureau of Prisons complex, was used in this comparative descriptive study of weight, body mass index (BMI), changes among inmates in different custody level institutions, and with different sentence lengths. Data were collected by record reviews retrospectively over a three-year period and the length of incarceration. This study is based on Roy's Adaptation Model. The total sample was heavier on admission than the general public. The sample shifted from normal to overweight individuals while the percentage of obese inmates showed small fluctuations. The mean BMI increase for the three-year period was statistically significant (t = 2.05, p = 0.04). The period of incarceration, which covered a longer time and had less missing data, produced results with greater statistical significance than the three-year period (t = 2.91, p = 0.004). In-custody inmates gained weight and had a significant mean BMI increase (t = 2.05, p = 0.05), while out-custody inmates experienced a non-significant BMI increase (t = 0.90, p = 0.38). Independent ttests comparing BMI changes by custody level were not significant (t = 0.96. p = 0.34). Inmates with shorter sentences (
