Objective: To analyze the association between average absorbent energy perday and Rohrer Index and total cholesterol(TC), high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) in local urban and rural children of school age,in order to provide some suggestions of children′s healthcare and provent trend of coronary heart disease in youth. Methods: Types and quantity of food within a week,body height,body weight,TC,HDL-C,LDL-C of 2220 local urban and rural children from 7 to 12 years-old(185 children in perage,respectively) were masured. Average absorbent energy perday and Rohrer Index were figured out,the association between them was analized. Rosuths: Average absorbent energy perday of six ages in urban children was7.11±0.43、7.19±0.57、7.36±0.95、8.44±1.12、8.95±1.62、9.80±1.97MJ,respectively,and that in rural children was5.34±0.22、5.53±0.31、6.02±0.37、6.68±0.41、7.22±0.77、7.95±0.83MJ, respectively. Rohrer Index of six ages in urban boies was115.43±4.56、130.79±5.73、100.89±3.27、121.38±2.83、120.13±3.12、112.97±3.12, respectively,and it was 100.17±1.09、103.79±2.19、103.87±2.09、102.98±3.15、99.37±1.79、112.34±3.03 in rural ones,respectively, it was 113.31±4.14、127.51±2.07、109.56±5.03、119.29±3.79、117.21±2.59、108.83±3.51 in urban girls , respectively, it was 98.93±2.43、96.10±4.07、96.65±3.83、96.49±3.01、97.21± 2.74、 108.22±3.21 in rural girls , respectively.Average absorbent energy perday and Rohrer Index of six ages were showed significant height in urban children, respectively(P<0.01, respectively).TC,HDL-C,LDL-C of all cases were normol. 141( 6.35%)obese children were performed in 2220 catases, they(9.25%) were higher in urban children than them(3.42%) in rural ones(P< 0.01),average absorbent energy perday correlated significantly with Rohrer Index (γ=0.32),but TC did not correlate with average absorbent energy perday and Rohrer Index in all obese children(P>0.05). Conclusion:Average absorbent energy perday and Rohrer Index were lower in rural children, but these achieved the goals in urban ones.Proportion of obese children were higher, average absorbent energy perday correlated significantly with Rohrer Index , TC did not correlate with average absorbent energy perday and Rohrer Index in all obese children.
