Abstract Objectives This study aimed to compare informal caregivers/dementia caregivers to non-caregivers regarding alcohol consumption, smoking behavior, obesity, and insufficient physical activity and to identify caregiving-related factors (caregiving intensity, length of caregiving, relationship to the care recipient, and type of caregiving task) which are associated with behavioral risk factors in caregivers/dementia caregivers. Methods Using cross-sectional data from the Behavioral Risk Factor Surveillance System, we performed the statistical analyses applying logistic regression models and accounted for confounding using the entropy balancing approach. Results For caregivers (n = 12,044), the odds of overweight/obesity and smoking were higher (OR = 1.14/1.34, p \ 0.05) and the odds of binge drinking and insufficient physical activity were lower (OR = 0.86/0.83, p \ 0.05) than for noncaregivers (n = 45,925). For dementia caregivers, results point in the same direction. Caregiving-related variables tend to influence the likelihood of behavioral risk factors, but depending on the kind of factor considered, in different directions. Conclusions Being a caregiver is associated with risky and health-promoting behavior. However, the effects are relatively low. Future studies should study potential pathways between caregiving characteristics, psychological impacts of caregiving, health behavior, and mental or physical health.

Introduction In the United States, an estimated number of 43.5 million adults provides unpaid care (National Alliance for Caregiving (NAC) and AARP Public Policy Institute 2015). The demand for so-called informal caregivers (CG) is

probably rising as the number of potential care recipients (population aged 65 plus) is projected to increase (United Nations 2017). The effects of informal caregiving on the CG have received considerable attention. Physical and mental health were primarily found to be negatively associated with informal caregiving (Bauer and Sousa-Poza 2015). However, more recent findings show that caregiving is also associated with benefits, such as personal growth and meaning of
