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 and AIP was determined. The mean AIP 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. Significantly higher AIP levels were observed in the PA1 and PA2 groups than the PA3 group, while no significant difference existed between the PA1 and PA2 groups. Physical activity significantly reduced the AIP after adjustment for 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 significantly 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 of AIP among middle-aged men in southeastern China.

The aim of this study was to determine the associations between cardiovascular health and the waist circumference (WC) and waist-to-height ratio (WHtR). A cross-sectional study was performed recruiting 26701 middle-aged Chinese men. Of the seven ideal cardiovascular health metrics, body mass index (BMI), total cholesterol (TC), blood pressure (BP), and fasting blood glucose (FBG) were found to increase with an elevation of the mean WC and WHtR. The mean WC and WHtR were significantly lower in the subjects with intermediate or ideal cardiovascular health than those with poor or intermediate health. After adjustment for age, the mean WC and WHtR decreased by 1.486 cm and 0.009 per 1-point increase in the cardiovascular health score, and 2.242 cm and 0.013 per 1-point increase in the number of ideal cardiovascular health metrics, respectively. The cardiovascular health score was negatively correlated with the WC (r = −0.387) and WHtR (r = −0.400), while the number of ideal cardiovascular health metrics was negatively associated with the WC (r = −0.384) and WHtR (r = −0.395). The cardiovascular health is correlated negatively with the WC and WHtR, and a stronger correlation existed between the cardiovascular health and WHtR than WC.

The aim of this study was to examine the correlation between aerobic exercise and the atherogenic index of plasma (AIP) in middle-aged Chinese men stratified by body weight.A cross-sectional study, which recruited 26,701 middle-aged Chinese men undergoing health examinations in our hospital from 1st January 2014 to 30th June 2015 was performed, and the associations between body weight and AIP, and aerobic exercise and AIP were evaluated.The mean AIP levels were -0.016±0.305, 0.138±0.3171 and 0.211±0.3243 in normal weight, overweight and obese subjects, respectively, and appeared to rise with body weight. Significantly higher AIP levels were observed in subjects with a weekly aerobic exercise period ≥90min than in those with a weekly aerobic exercise period90min, and the mean AIP levels were -0.038±0.3015, 0.117±0.3182 and 0.192±0.3209, and were 0.003±0.3067, 0.156±0.3149 and 0.225±0.3263 in normal weight, overweight and obese men with a weekly aerobic exercise period ≥90min and90min, respectively. In addition, aerobic exercise significantly reduced AIP after adjustment for age, systolic blood pressure, diastolic blood pressure, body mass index (BMI), fasting blood glucose and uric acid.Lowering body weight and/or increasing aerobic exercise time may reduce AIP, and lowering body weight results in a greater reduction in AIP than aerobic exercise. Weight control combined with increased aerobic exercise time may cause a synergistic effect on the reduction of AIP.

The American Heart Association aims to improve cardiovascular health by encouraging the general population to meet 7 cardiovascular health behaviors and factors. The atherogenic index of plasma (AIP) is an important index. Our aim is to evaluate the relationship between ideal cardiovascular health and the atherogenic index of plasma (AIP) in middle-aged Chinese men. A cross-sectional study was performed. A total of 27,824 middle-aged Chinese men were enrolled. The association between ideal cardiovascular health behaviors and factors and AIP was determined. The 7 cardiovascular health metrics were scored as follows: 0, poor; 1, general; and 2, ideal. The cardiovascular health status was classified according to the total score, as follows: 0 to 4, inadequate; 5 to 9, average; and 10 to 14, optimum. Analyses assessed the prevalence of 7 cardiovascular health metrics, its association with AIP. Logistic regression models were used to calculate odds ratios (ORs), adjusting for age. All 7 cardiovascular health metrics were shown to correlate with AIP (all P values
