To the Editor: The study by Dr Stringhini and colleagues1 has again demonstrated a gradient in mortality, with lower socioeconomic position associated with higher mortality. Behaviors such as smoking, unhealthy diet, low levels of physical activity, and low alcohol consumption were strongly related to mortality. These behaviors were more prevalent among participants in the lower socioeconomic position.
