Change = 6 months follow-up findings − baseline findings.
Values in bold type indicate change is significantly different from zero and from nonbold values (P ≤ .05 for familywise error rate); exceptions noted in footnotes d and f.
Measured by the Healthy Eating Index-2005 (13).
For treatment comparisons, difference between low and high participation intervention group means is significant (P ≤ .05 for familywise error rate); difference between control and high participation intervention group means is trending for significance (.05 < P ≤ .10 for familywise error rate).
The independent (predictor) variable was not included in the model because it was not significant. Least squares means cannot be calculated for variables not included in models.
For treatment comparisons, difference between control and high participation intervention group means is significant (P ≤ .05 for familywise error rate); difference between control and low participation intervention group means is not significant (P > .05 for familywise error rate).
Employed and retired group means were significantly greater than unemployed group mean (P ≤ .05 for familywise error rate).
