ABSTRACT

BACKGROUND: Increased physical activity (PA) is as a cornerstone for the prevention
and the treatment of diabetes mellitus (DM) and frailty. However, no consensus exists on
which type of PA [aerobic or resistance training (RT)] and which specific patterns of PA,
and sedentary behaviour are associated with frailty status among individuals living with
DM.

OBJECTIVE: To investigate the association between bouts and patterns of PA, RT, and
sedentary behaviour on frailty status in males and females living with DM.

METHODS: A cross-sectional analysis of the 2003-2006 cycles from the National Health
and Nutrition Examination Survey (NHANES) was performed in 711 participants living
with DM. Frailty status was measured using the 46-item deficit model and DM was selfreported.
PA levels were measured by accelerometer, while RT was measured via questionnaire.

RESULTS: RT was not significantly associated with frailty status in men and women,
while total time in light PA was negatively associated with frailty status in men (p<0.001)
and women (p<0.0001). Total moderate-to-vigorous PA (MVPA) and every bout of MVPA
were negatively associated with frailty status in women only (p<0.05), while sedentary
behaviour was positively associated with increased frailty status in women (p<0.05). Each
bout of MVPA were associated with a 5 per cent and 6 per cent lower likelihood of frailty in men and
women respectively (all p<0.05).

CONCLUSIONS: Overall, our results suggest that RT is not associated with improved
frailty status in men and women living with DM. However, time spent engaged in light PA
is associated with reduced frailty status in men and women living with DM. MVPA showed
a reduced association with frailty status in women only, and sedentary behaviour showed
an increased association with frailty status in women only.
