The correlation between the weekly duration of aerobic exercise and atherogenic index of plasma
(AIP) is still unknown. A cross-sectional study was conducted involving 27,827 middle-aged Chinese men who had health examinations in our hospital.The correlation between the duration of moderate-intensity aerobic exercise andAIP was determined.The meanAIP levels were 0.1166 ± 0.34475, 0.1167 ± 0.32637, and 0.0765 ± 0.32872 in the non-exercise (PA1), occasional exercise (PA2), and frequent exercise groups (PA3), respectively. Signifcantly higherAIP levels were observed in the PA1 and PA2 groups than the PA3 group, while no signifcant diference existed between the PA1 and PA2 groups. Physical activity signifcantly reduced theAIP after adjustmentfor age, body mass index, diastolic blood pressure, and fasting blood glucose and uric acid levels. In addition,the percentage of the population at high risk for atherosclerosis (AIP ≥ 0.21) was signifcantly lower in the PA3 group than the PA1 and PA2 groups. Moderate-intensity aerobic exercise at a weekly duration of 90 min or longer is associated with the reduction ofAIP among middle-aged men in southeastern China.
