Unweighted sample size. Due to missing responses, the total sample size for analysis by duration of caregiving does not equal that for analysis by intensity of caregiving and percentage may not be added up to 100%.
Age-adjusted to the 2000 projected U.S. population aged ≥18 years. https://www.cdc.gov/nchs/data/statnt/statnt20.pdf
Adjusted prevalence ratio and 95% confidence interval (CI) were derived from multivariable logistic regression model among caregivers with sex, age group, race/ethnicity, education, employment status, marital status, BMI category, cigarette smoking status, leisure-time physical activity, number of caregiver’s chronic condition, and care recipient’s condition.
Caregiver’s chronic condition including diabetes, asthma ever, chronic obstructive pulmonary disease (COPD), coronary heart disease (heart attack, myocardial infarction or angina), stroke, arthritis, any cancer, depression, or chronic kidney disease.
Major chronic condition including arthritis/rheumatism, asthma, chronic respiratory conditions such as emphysema or COPD, diabetes, heart disease, hypertension, stroke, human immunodeficiency virus infection (HIV), other organ failure or disease such as kidney or liver problems.
