Differential changes in body mass index after retirement by occupation: hierarchical models

Objectives:
This paper examines whether retirement differentially affects body mass index (BMI) patterns by occupation; occupation embodies differences in on-the-job physical demands as well as socioeconomic characteristics that could lead to variation in post-retirement BMI.
Methods:
We use 12 years of national data from the US and hierarchical linear models to compare BMI trajectories among four broad occupational classes.
Results:
We find that those in service and other blue-collar occupations have significant increases in the slopes of their BMI trajectories after retirement, whereas participants in white-collar occupations exhibit no change. This may be due to differences in the physical requirements across blue and white collar jobs or differences in health habits post-retirement.
Conclusions:
Retirement may provide an opportunity to help prevent obesity in older individuals, especially blue collar workers.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
