Physical status as a moderator of depressive symptoms among older adults with dual sensory loss

This study evaluated the ability of three measures of physical status-physical activity, physical condition, and body mass index (BMI)-to moderate the relationship between dual sensory loss (DSL) and depressive symptoms in older adults.

Nationally representative longitudinal data were used to develop multilevel models predicting depressive symptoms among two groups of older adults, 1380 who developed DSL during the study and 1308 without sensory loss.

All three measures were associated with depressive symptoms for persons who had or would develop a DSL: participation in physical activity and being in better physical condition were associated with lower levels of depressive symptoms, while lower BMI levels were associated with higher levels of depressive symptoms. All moderator variables had a larger effect for persons with DSL as compared to persons without sensory loss.

The implication of these findings is that participation in a regular program of physical activity may provide multiple benefits to older persons with DSL. Families and health care providers can offer support for being physically active by ensuring the person has the best possible correction for the sensory losses, providing encouragement, and/or providing physical assistance with exercise.
