To the Editor: Dr Chiuve and colleagues found that adherence to a low-risk, healthy lifestyle was associated with a low risk of sudden cardiac death (SCD) in women.1 A previous study that used the same cohort as Chiuve et al (the Nurses' Health Study) reported that depressive symptoms were associated with risk of SCD in women without baseline coronary heart disease.2 Depressive symptoms are common and could interfere with adherence to health behaviors. In large, population-based samples in Israel, we found that depressive symptoms were associated with nonadherence to low-risk, healthy lifestyle behaviors in individuals with diabetes,3 hypertension,4 and asthma.5
