Background

Multiple chronic conditions may erode physical functioning, particularly in the context of complex self-management demands and depressive symptoms. Yet, little is known about how discordant conditions (i.e., those with management requirements that are not directly related and increase care complexity) among couples are linked to functional disability.

Purpose

We evaluated own and partner individual-level discordant conditions (i.e., discordant conditions within individuals) and couple-level discordant conditions (i.e., discordant conditions between spouses), and their links to levels of and change in functional disability.

Methods

The U.S. sample included 3,991 couples drawn from nine waves (1998-2014) of the Health and Retirement Study. Dyadic growth curve models determined how individual-level and couple-level discordant conditions were linked to functional disability over time, and whether depressive symptoms moderated these links. Models controlled for age, minority status, education, each partner's baseline depressive symptoms, and each partner's number of chronic conditions across waves.

Results

Wives and husbands had higher initial disability when they had their own discordant conditions and when there were couple-level discordant conditions. Husbands also reported higher initial disability when wives had discordant conditions. Wives had a slower rate of increase in disability when there were couple-level discordant conditions. Depressive symptoms moderated links between disability and discordant conditions at the individual and couple levels.

Conclusions

Discordant chronic conditions within couples have enduring links to disability that partly vary by gender and depressive symptoms. These findings generate valuable information for interventions to maintain the well-being of couples managing complex health challenges.

Objective

Chronic conditions in middle and later life are associated with lower physical activity. Yet little is known about chronic condition discordance (i.e., the extent to which conditions have nonoverlapping self-management requirements) within older individuals and couples and its implications for physical activity. We determined how the degrees of chronic condition discordance at the individual level and the couple level (i.e., between spouses) were linked to moderate physical activity across an 8-year period.

Method

The U.S. sample included 1,621 couples from five waves of the Health and Retirement Study (2006-2014). Dyadic growth curve models estimated how individual-level and couple-level chronic condition discordance were linked to initial levels of and rates of change in moderate activity. Models controlled for age, minority status, education, and own and partner reports of baseline negative marital quality, time-varying depressive symptoms, and time-varying number of chronic conditions.

Results

A considerable proportion of wives (25.4%) and husbands (18.9%) reported moderate activity less than once a week. When individuals (wives: β = -0.10; husbands: β = -0.09) or their spouses (wives: β = -0.04; husbands: β = -0.05) had greater individual-level chronic condition discordance, lower initial moderate activity was reported. When husbands had greater individual-level discordance, both wives (β = -0.16) and husbands (β = -0.19) had a faster rate of decline in moderate activity over time. Couple-level chronic condition discordance was not significantly linked to moderate activity.

Conclusions

These findings suggest the importance of promoting physical activity among individuals and couples managing complex chronic conditions. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Objectives

Individuals often manage chronic conditions in middle and later life that may diminish well-being. Little is known, however, about discordant conditions (i.e., two or more conditions with competing self-management requirements) among older couples and their links to depressive symptoms. We considered discordant conditions at both the individual level and the couple level (i.e., between spouses), along with their long-term implications for depressive symptoms.

Methods

The U.S. sample included 1,116 middle-aged and older couples drawn from five waves (2006-2014) of the Health and Retirement Study. Longitudinal actor-partner interdependence models evaluated whether individual-level and couple-level discordant chronic health conditions were concurrently linked to depressive symptoms, and whether these associations became stronger over time. Models controlled for age, minority status, education, prior wave depressive symptoms, and each partner's baseline report of negative marital quality and number of chronic conditions in each wave.

Results

Wives and husbands reported significantly greater depressive symptoms when they had individual-level discordant conditions about 2 years after baseline, and these links intensified over time. Beyond this association, husbands had significantly greater depressive symptoms when there were couple-level discordant conditions.

Discussion

Individual-level and couple-level discordant conditions may have lasting implications for depressive symptoms during midlife and older adulthood.

Chronic health conditions among individuals and their partners may diminish perceived control, particularly when these conditions are highly complex. We considered how chronic condition discordance (i.e., the extent that two or more conditions have nonoverlapping self-management requirements) at the individual level and the couple level (i.e., between spouses) was linked to health-related control and personal mastery across an 8-year period, and whether these links varied by age. The U.S. sample included 879 wives (M = 53.81 years) and husbands (M = 57.19 years) from three waves (2006, 2010, and 2014) of the Health and Retirement Study. Dyadic growth curve models controlled for age, minority status, education, own and partner baseline negative marital quality, and own and partner time-varying depressive symptoms, and number of chronic health conditions. Overall, both individual-level and couple-level degrees of chronic condition discordance were associated with initial levels of and rates of change in perceived control. When wives had greater individual-level discordance, they reported lower initial personal mastery. When husbands had greater individual-level discordance, they reported lower initial health-related control and faster declines in health-related control and personal mastery, and their wives reported faster declines in personal mastery. When there was greater couple-level discordance, wives reported lower initial health-related control. Age moderated the associations between wives' individual-level discordance and their own initial level of health-related control and rate of change in personal mastery. Interventions to improve later-life well-being may be enhanced by targeting increases in perceived control among individuals and couples managing complex patterns of chronic conditions.
