Do economic stresses influence child work hours on family farms?
Increased child work hours may be associated with periods of higher farm sector productivity, rather than economic stress per se. Findings are limited by the ecologic study design, use of national economic indicators, and the limited number of cycles of child work hours available for time series analysis. Economic conditions may influence decisions about children's farm work.
Pericardial fat is associated with atrial conduction as quantified by PWI, even with adjustment for extracardiac fat depots. Further studies are warranted to identify the mechanisms through which pericardial fat may modify atrial electrophysiology and promote subsequent risk for arrhythmogenesis.
