Retirement status and physical activity in US adults with type 2 diabetes mellitus: Influence of sex, race/ethnicity and acculturation level

Aims

We aimed to assess the association between retirement status and recreational physical activity (rPA) in US adults with Type 2 diabetes mellitus (T2DM), while accounting for potential modification effects.

Methods

We extracted data from the 2007–2014 National Health and Nutrition Examination Survey. We used logistic regression models to evaluate the association between self-reported retirement status and high rPA (i.e., at least 150 min/week). We reported adjusted odds ratio (aOR) and 95% confidence intervals (95% CI). We estimated the modification effect of sex, race/ethnicity, and acculturation level by including interaction terms into the models.

Results

Of the 992 U.S. adults with T2DM, 34.8% was retired. As a whole, retirement was associated with high rPA (aOR=1.87 [95% CI: 1.16–3.00]; P = 0.0110). Retirement was associated with high odds of rPA in females (aOR=2.07 [95% CI, 1.14, 3.73], P = 0.0171), in non-Hispanic whites (aOR=2.57 [95% CI, 1.32, 5.00], P = 0.0062), and in those with high acculturation level (aOR=1.85 [95% CI, 1.07, 3.19], P = 0.0273). We observed no significant statistical interactions.

Conclusions

Retirement is associated with a high participation to rPA in US adults with T2DM, and the amplitude varies by sex, race/ethnicity and acculturation level. Intervention for improving rPA in adults with T2DM should collect and consider information on retirement status.
