【摘要】：一、研究背景肥胖是兒童青少年人群中主要的公共衛(wèi)生問題,青少年的屏前行為是肥胖可以干預(yù)的影響因素之一。目前國(guó)內(nèi)尚缺乏針對(duì)我國(guó)城市青少年課余屏前行為在流行現(xiàn)況、對(duì)健康的影響、行為的影響因素和干預(yù)策略的系統(tǒng)性研究。二、研究目標(biāo)通過對(duì)上海市初中學(xué)生為研究人群的現(xiàn)場(chǎng)流行病學(xué)研究和健康促進(jìn)干預(yù)試驗(yàn),掌握青少年屏前行為的現(xiàn)況,分析屏前行為與超重、肥胖的關(guān)聯(lián),驗(yàn)證過長(zhǎng)屏前行為的時(shí)間界值,分析心理因素和家庭環(huán)境對(duì)過長(zhǎng)屏前行為的影響。開展以生活技能教育為基礎(chǔ)的干預(yù),探索個(gè)性特征因素對(duì)干預(yù)效果的影響,為促進(jìn)青少年健康和開展有效的干預(yù)提供依據(jù)。三、研究方法1、青少年靜態(tài)行為與屏前行為研究。2011年采用多階段抽樣法抽取三個(gè)區(qū)3所中學(xué)的學(xué)生自行填寫調(diào)查表,對(duì)學(xué)生上學(xué)日和周末的整日各個(gè)活動(dòng)分類匯總和分析。對(duì)數(shù)據(jù)進(jìn)行描述性分析、相關(guān)性分析和Kruskal-Wallis檢驗(yàn)。2、上海市青少年課余屏前行為與肥胖的研究。采用二階段隨機(jī)抽取四個(gè)區(qū)9所中學(xué)6-9年級(jí)的學(xué)生進(jìn)行調(diào)查。在以上調(diào)查的對(duì)象中抽取6所學(xué)校開展血生化檢測(cè)。數(shù)據(jù)進(jìn)行了描述性分析,采用二項(xiàng)次Logistic回歸等進(jìn)行多因素分析。3、青少年課余屏前行為現(xiàn)況與影響因素研究。對(duì)上海市青少年屏前行為的現(xiàn)況進(jìn)行調(diào)查分析,分析心理和家庭因素對(duì)過長(zhǎng)屏前行為的影響。采用二階段隨機(jī)抽取四個(gè)區(qū)9所中學(xué)6-9年級(jí)的學(xué)生進(jìn)行調(diào)查。分別進(jìn)行了描述性分析,采用二項(xiàng)次Logistic回歸等方法進(jìn)行多因素分析。4、青少年過長(zhǎng)課余屏前行為干預(yù)研究。運(yùn)用社會(huì)認(rèn)知理論和生活技能教育的方法來探索適宜的干預(yù)模式,評(píng)估干預(yù)的效果和干預(yù)效果的影響因素,以達(dá)到降低中學(xué)生不良電子屏幕行為和肥胖率的目的。準(zhǔn)試驗(yàn)研究設(shè)計(jì),設(shè)有干預(yù)組和對(duì)照組�；€和效果評(píng)估的調(diào)查均包括問卷調(diào)查、體格檢查和學(xué)校環(huán)境的調(diào)查。干預(yù)措施基于社會(huì)認(rèn)知理論的框架,內(nèi)容包括生活技能教育教材、教案和教具的制作,以生活技能教育為主要內(nèi)容開設(shè)試點(diǎn)干預(yù)學(xué)校健康教育課,給學(xué)生和家長(zhǎng)發(fā)放健康行為塑造的小冊(cè)子,開展學(xué)校-家庭共同參與的專題討論等。分別進(jìn)行了描述性分析、多因素分析,采用協(xié)方差分析、二項(xiàng)次Logistic回歸等方法進(jìn)行多因素分析。四、研究結(jié)果1、青少年靜態(tài)行為與屏前行為研究：周末調(diào)查對(duì)象的靜態(tài)行為是每天389.19分鐘、屏前行為的時(shí)間是每天122.93分鐘。青少年的靜態(tài)行為時(shí)間與中重度體力活動(dòng)無關(guān),與輕度體力活動(dòng)呈負(fù)相關(guān)。不同營(yíng)養(yǎng)狀況青少年的周末的屏前時(shí)間均值的差異有統(tǒng)計(jì)學(xué)意義。2、上海市青少年課余屏前行為與肥胖的研究：肥胖組與非肥胖組組比較,屏前時(shí)間過長(zhǎng)的比率較高,同時(shí)肥胖組的父母BMI值較大、男生較多、喝含糖飲料的概率較大、每天鍛煉60分鐘的天數(shù)少、與同齡的孩子相比飯量較大,年齡較小。本研究沒有發(fā)現(xiàn)過長(zhǎng)屏前時(shí)間學(xué)生的血清葡萄糖、胰島素、總膽固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白、C-反應(yīng)蛋白的均值相對(duì)增高。經(jīng)過驗(yàn)證,在調(diào)整了年齡、性別和交互作用后界值為1.43個(gè)半小時(shí)的時(shí)候,過長(zhǎng)屏前時(shí)間對(duì)青少年健康已經(jīng)產(chǎn)生影響。關(guān)于過長(zhǎng)屏前時(shí)間的界值的驗(yàn)證還需要在更多的健康問題當(dāng)中,并且在不斷完善屏前時(shí)間測(cè)量和調(diào)查的方法的基礎(chǔ)上進(jìn)一步驗(yàn)證。3、青少年課余屏前行為現(xiàn)況與影響因素研究：本次調(diào)查青少年學(xué)生在一周內(nèi)平均每天的屏前時(shí)間的平均值是2.68小時(shí),其中男生為2.92小時(shí),女生為2.47小時(shí)。51.5%的調(diào)查對(duì)象平均每天屏前時(shí)間大于或等于2小時(shí)。關(guān)于心理因素的影響,過長(zhǎng)屏前行為的學(xué)生當(dāng)中,不良環(huán)境的影響、自卑傾向和學(xué)習(xí)壓力對(duì)屏前時(shí)間的影響顯著。在家庭環(huán)境中影響過長(zhǎng)屏前時(shí)間的因素包括擁有電子設(shè)備、家庭對(duì)屏前時(shí)間沒有約束、父母親的屏前行為過長(zhǎng)、母親的文化程度不高。4、青少年過長(zhǎng)課余屏前行為干預(yù)研究：經(jīng)過1年的干預(yù),評(píng)估結(jié)果發(fā)現(xiàn)目標(biāo)行為沒有達(dá)到預(yù)期的效果。在控制了性別和分組的影響之后,神經(jīng)質(zhì)和掩飾性與行為的改變有關(guān)。在干預(yù)研究中,實(shí)驗(yàn)組和對(duì)照組的人格特征分布不同,有可能會(huì)影響干預(yù)的效果。五、研究結(jié)論結(jié)論：屏前行為已經(jīng)是上海市青少年普遍的行為。過長(zhǎng)屏前行為與肥胖等多種健康問題有關(guān)。青少年過長(zhǎng)屏前行為受到家庭因素和心理因素的相互影響,屏前行為的干預(yù)效果除了干預(yù)措施的影響之外,也受到個(gè)性特征的影響。
[Abstract]:First, the study of background obesity is the main public health problem among children and adolescents. The pre screen behavior of adolescents is one of the factors that affect obesity. At present, there is a lack of systematic study on the impact of pre screen behavior on health, the influence factors of behavior, and intervention strategies in China's urban adolescents. Two. Through the field epidemiological study and health promotion intervention test of the junior middle school students in Shanghai, the study aims to understand the present situation of young people's pre screen behavior, analyze the correlation between pre screen behavior and overweight and obesity, and verify the time value of the behavior before the long screen, and analyze the shadow of psychological factors and family environment on the long screen behavior. Sound. Carry out the intervention based on life skill education, explore the influence of personality factors on the effect of intervention, and provide the basis for promoting the health and effective intervention of young people. Three, research methods 1, the study on the static behavior and pre screen behavior of young people in.2011, using multi stage sampling method to extract students from three districts and 3 middle schools. The questionnaire survey and analysis of students' daily activities on the day and weekend. Descriptive analysis of the data, correlation analysis and Kruskal-Wallis test.2, study on the pre screen pre screen behavior and obesity in Shanghai adolescents. The two stage randomly selected 6-9 grade students from 9 middle schools in four districts were investigated. 6 schools were selected to carry out blood biochemical tests in 6 schools. The data were analyzed with descriptive analysis, and multiple factor analysis of two times Logistic regression was used for multiple factor analysis.3. The present situation and influencing factors of juvenile extracurricular activities were studied. The status of pre screen behavior of young people in Shanghai was investigated and analyzed, and the psychological and family factors were analyzed before the long screen. In the two stage, the students of grade 6-9 of 9 middle schools in four districts were randomly selected to carry out a survey. The descriptive analysis was carried out, and the multi factor analysis of.4 was carried out with the methods of two Logistic regression and so on. The intervention model was used to assess the effect of intervention and the influencing factors of intervention effect in order to reduce the negative electronic screen behavior and obesity rate of middle school students. A quasi trial design was designed with an intervention group and a control group. The survey of baseline and effect assessment included questionnaire survey, physical examination and the investigation of school environment. Intervention measures were based on society. The framework of the cognitive theory includes the teaching materials of life skills, the production of teaching plans and teaching aids, the establishment of a pilot intervention in school health education, the distribution of healthy behavior to students and parents, and the discussion of the joint participation of schools and families. Multifactor analysis, covariance analysis, two Logistic regression and other methods were used to carry out multifactor analysis. Four. Study results 1. Study on the static behavior and pre screen behavior of adolescents: the static behavior of the subjects at the weekend was 389.19 minutes a day and the time of pre screen behavior was 122.93 minutes a day. The static behavior time and the medium and severe body time of the young people were two. There was a negative correlation between the force activity and the mild physical activity. The difference in the mean value of the pre screen time for the adolescents with different nutritional status was statistically significant.2. The study on the pre screen behavior and obesity in Shanghai adolescents: the ratio of the obese group to the non obese group was higher than that in the non obese group, and the BMI value of the parents in the obese group was higher. Boys were more likely to drink sugar drinks with a larger number of days of exercise 60 minutes a day. Compared with children of the same age, their meals were larger and younger. The study did not find that the average levels of serum glucose, insulin, total cholesterol, triglycerides, HDL, LDL, C- reactive protein were relatively increased in the study. High. It is verified that over 1.43 and a half hours after the adjustment of age, gender and interaction, the long pre screen time has an impact on adolescent health. The validation of the boundary value of the long screen time needs more health problems, and the basis for improving the methods of measuring and investigating pre screen time. Study on the current status and influencing factors of.3, young students' Extracurricular pre screen behavior: the average average daily pre screen time of young students in one week was 2.68 hours, of which boys were 2.92 hours, and girls with 2.47 hours.51.5% were more than or equal to 2 hours per day. In the family environment, the factors that affect the length of the screen in the family environment include electronic equipment, the family has no restraint on the pre screen time, the parents' pre screen behavior is too long, and the mother's level of culture is not high.4, After 1 years of intervention, the results found that the target behavior did not achieve the desired effect. After controlling the effects of sex and grouping, the neuroticism and the disguise were related to the change of behavior. In the intervention study, the personality characteristics of the experimental group and the group were different and may be affected. The effect of sound intervention. Five. Conclusion: pre screen behavior has been a common behavior of adolescents in Shanghai. Excessive pre screen behavior is related to a variety of health problems, such as obesity. The behavior of young adults is influenced by family and psychological factors. The intervention effect of pre screen behavior is also influenced by the intervention measures. The influence of personality traits.
