Longitudinal surveillance for chronic health conditions in former United States Department of Energy Site Workers.

Objective: To determine (1) the rate at which rescreening former Department of Energy site workers identifies non-communicable chronic diseases and (2) the development of comorbid conditions.

Methods: Incidence and prevalence of hypertension, diabetes, reduced kidney function, and peripheral neuropathy at both initial and return screenings were calculated. Risk ratio of chronic disease development at return screening based on the presence of other conditions at initial screening were estimated with generalized linear regression.

Factors linked to participant attrition in a longitudinal occupational health surveillance program.

Background: For occupational medical screening programs focused on long-term health surveillance, participant attrition is a significant barrier to success. We investigate demographic, medical history, and clinical data from National Supplemental Screening Program (NSSP) examinees for association with likelihood of return for a second exam (rescreening).

Methods: A total of 15,733 individuals completed at least one NSSP exam before December 31, 2016; of those, 4832 also completed a second exam on or before December 31, 2019.

Development of cortical bone geometry in the human femoral and tibial diaphysis.

Ontogenetic growth processes in human long bones are key elements, determining the variability of adult bone structure. This study seeks to identify and describe the interaction between ontogenetic growth periods and changes in femoral and tibial diaphyseal shape. Femora and tibiae (n = 46) ranging developmentally from neonate to skeletally mature were obtained from the Norris Farms No.
