Objectives:By research and analysis the distribution, physical characteristics and influence factors of adults 40-59 years of age in Coastal city of Shandong Province, the purpose of this study is to provide reference for prevention and control for their overweight and obesity.Methods:In the means of the physical monitoring equipment specified by the China center of National Physical Fitness Surveillance and questionnaire, 2740 adults,40-59 years of age was monitored and surveyed in the coastal city of Shandong Province (Qingdao, Yantai, Weihai, Rizhao) in May 2010, and the data acquisition software is developed by China center of National Physical Fitness Surveillance.(1)Morphological Indicators:height,weight, measurements of the chest, waist and hips, skinfold thickness of the upper arm, scapular and abdomen(2)Function Indicators: quiet pulse,systolic blood pressure,diastolic blood pressure vital capacity,step test index.(3)Quality Indicators:sit-and-reach holding power,single-leg with eyes close,choice reaction timeAccording to the "China adult overweight and obesity prevention and control guidelines"(Trial), which was promulgated by the Division of Disease Control Ministry of Health in March 2003, the data was statistical analysized by SPSS.Result:1.The overall prevalence of overweigh of adults aged 40-59 in Coastal cities of Shandong Province was 48.3% and the overall obesity rate was 22.8%. There are no significant difference in rates of overweight and obesity between different sexes(p>0.05).In the age distribution, the overall rates of overweight and obesity of adults of 40-59 years old in the coastal city of Shandong Province is raised with age growth,the rates of male overweight between different ages is higher than that of female, the rate of male overweight before 50 is higher than that of female, and the result is turned for the female to male after 50.In different kinds of jobs, the rate of overweight of urban manual workers is higher than that of urban non-manual workers, there is no significant difference taken by chi-square test(Χ2=1.832, p=0.176>0.05);the rate of obesity of urban manual workers is lower than that of urban non-manual workers, there is significant difference taken by chi-square test(Χ2=8.730,p= 0.003 <0.05).In the education level, the overall rates of overweight of adults of 40-59 years old in the coastal city of Shandong Province is increased with the growth of education level, while the rate of obesity is opposite. Through the correlation analysis, the effect of age on BMI is the greatest.2.Overall compliance rate of obesity is lower than that of overweight and normal persons. As for the morphological indicators, the rate of overweight and obesity group of the same sex is significantly higher than the normal group; all function and quality of the overweight and obesity group is lower than the normal one, the obesity group is the lowest.In addition to some indicators such asresting heart rate, lung capacity, eyes closed, standing on one foot and choice reaction time, there are significant correlation between gender BMI and the other indicators.3.Through Multivariate Logistic regression analysis, factors influencing overweight independent were age,sex,educational level and passive activities, And the independent factors influencing obesity were the level of education, staying up late, life stress and work status.Conclusion:1. The rate of overweigh and obesity of adults aged 40-59 in Coastal cities of Shandong Province is higher.The overweight rate of male and female is raised with age growth, The obesity rate of male is descent with age growth.This may be related to their living forms. The obesity rate of female is raised with age growth.This may be related to their physiological functions.2. In different kinds of jobs, the overweight rate of urban manual workers is lower than that of urban non-manual workers, while the rate of obesity is opposite.The reason of this may be relate to this factors such as work forms, living condition,diet habits and so on. In the education level, the obesity rate of female is descent with the growth of education level,this may be related to their health sence and obesity knowledge which they mastered.The most of male overweight and obesity have higher education level,this may be related to their diet habits and few physical activities.The higher education level of male and the lower education level of female should be concerned.3.
