Multinomial Logistic regression showed that having heart disease, being stroke or hemiplegy, worrying about their children, living alone, having conflict with relatives, the frequency of negative life events, self-percieving economy, frequency of communicating with friends were influencing factors and being fond of watching TV or playing cards or Majiang, getting help when needed and having friends who could be trusted in may decrease the incidence of geriatric depression.

结果：(1) 1236名调查对象中，老年抑郁症89例，发病率为7.2％；(2)多元Logistic回归分析显示：是否患有心脏病、中风或偏瘫，是否担心子女、独居、与亲友有冲突，有无看电视，打牌或打麻将，能否获得需要的帮助，有无可信任的朋友，经济自评，与朋友交流的频率，负性生活事件次数对老年抑郁症的发病率的影响有统计学意义，是老年抑郁症发病率的影响因素；(3) GMS量表自动诊断系统AGECAT在农村社区老年抑郁症流行病学调查中应用时，具有较高的信度和效度。

However, after introducing these variables in nominal logisticand proportional hazard multiple regression models, only highCormack and Lehane grade during direct laryngoscopy, high upperlip bite test score, and short sternothyroid distance were significantlyassociated with multiple attempts or lengthier intubations.

然而，在 logistic 及比例风险多元回归模型中分析这些变数发现只有直接喉镜 Cormack 和 Lehane 等级高、上唇咬诊评分高及甲颏距离短与插管时间长或多次尝试显著相关。

The program of AER+RES was similar to AER, but went through resistance exercise 20min in base section of every exercise trail.Result: Prior to intervention, adiponectin levels were significantly correlated with BMI、 WHR、 COS、 LN、 LN、 TG、 LG10、 LN、 weight、 waist、 FM、%F, and leptin levels were significantly correlated with BMI、 WHR 、 LN 、 LN 、 TG 、 HDL-C 、 LG10、 apoB 、 apoA1/apoB、 waist、 F1M、%F. Stepwise multiple regression analysis revealed that LG10; COS and waist was an predictor of basal adiponectin levels , and %F,apoB and WHR was an predictor of basal leptin levels. In early obesity, adiponectin and leptin can be worsened , along with the changed of body component, fasting plasm glucose and lipid accumulation. After intervention, both group were significantly reduction in FM,%F,weight, WHR,FPG and TG, while HDL-C had significantly increased.AER exhibited significant in leptin, while AER+RES did not show the change. Insulin and HOMA-IR were changed in both groups. The control group exhibited no significant change in any variables. Although adiponectin levels were unchanged in the three groups, a significant negativecorrelation between delta %F, delta WHR and delta FPG was observed. Futhermore, if compare the degree of delta weight, we fought a significant increased in adiponectin between the group of delta weight higher (=3kg) than delta weight lower(=0kg), delta %F, delta WHR and delta weight were significant negative correlation with delta leptin.

结果：绝经妇女脂联素水平与体重指数、腰臀比、空腹血糖、空腹胰岛素、LEP、TG、极低密度脂蛋白胆固醇、胰岛素抵抗指数、体重、腰围、体脂含量、体脂百分比显著相关；瘦素水平与BMI、WHR、FINS、LEP、TG、HDL-C、VLDL-C、载脂蛋白B、apoA1／apoB、腰围、FM、％F等指标显著相关；多元逐步回归分析显示LG10、COS和腰围是基线脂联素水平的预测变量，而％F，apoB和WHR是基线瘦素水平的预测变量；在肥胖前期，脂联素、瘦素已经出现明显不良变化，同时也伴随着体成分、空腹血糖和血脂的异常；运动实验后，两个运动组的FM、％F、体重、WHR、FPG、TG都显著下降，而HDL-C显著上升；AER组瘦素显著下降，而AER+RES组则没有显著变化；两组的胰岛素和HOMA-IR水平都有显著下降；对照组所有指标都没有明显变化；尽管运动后脂联素水平没有显著变化，但是脂联素变化量与％F、WHR和血糖变化量显著负相关，而且如果按照运动后体重下降的程度比较，则体重下降大(≥3kg)的受试者比下降小的(≤0kg)脂联素水平有明显升高；运动后瘦素水平的变化量与％F，WHR及体重的变化量显著负相关。
