The Spread Of Health Behaviors In Social Network And Its Health Impacts

With the development of social economy and changes in lifestyle,chronic noncommunicable diseases have become a major public health problem affecting the sustainable development of China’s economy and society.The practice of prevention and control of chronic diseases shows that,it can effectively reduce the incidence of chronic disease and premature mortality by changing people’s health behavior.Therefore,researchers need to explore the factors that affect health behaviors and their mechanisms of action,in order to propose more reasonable intervention strategies for healthy behaviors,thus improving public health.At present,the researches on health behavior are mainly focused on individual and environmental factors,but neglecting the spread of health behaviors.Therefore,using the social network analysis method and the longitudinal analysis model,this paper researched the impact of social relationships on health behaviors.At the same time,the influence of social relationship factors,such as relationship type and relationship intensity,on behavior transmission were also analyzed.Furthermore,this paper studies the impacts of passive health behavior on individual’s health.The main research contents are as follow:First,this study developed a health behavior speading model in social networks,highlighted the importance of induction in behavior transmission,and emphasized the difference in the effects of social relationship types on various healthy behaviors.By constructing the generalized estimating equation model,this study quantitatively analyzed the nature and extent of the healthy behavior spread among individuals,and adopted a variety of methods to eliminate multiple interference factors.In addition,this paper studied the different effects of relationship types on the spread of healthy behaviors.The results suggested that both health protective behaviors and health harmful behaviors are transmitted in a quantifiable way in social networks,and the transmission of these behaviors is mainly induced by their social relationships.The spread of healthy behaviors can change dramatically with different relationship types,where the spreading dynamics on some special relationships disappear or even change to be reversed.Second,this study expanded the social relations factors,divided social relationships into three levels: relationship type,relationship scope,and relationship closeness,revealed the important impacts of relationship scope and relationship closeness on adolescents’ health behavior.From the relationship type,the relationship scope,and adolescents’ subjective perceived relationship closeness,the impacts of social relationships factors on adolescents’ health behavior were deeply analyzed.The results showed that,the three relationship factors have a significant positive effect on adolescents’ physical inactivity,but such social influence on male and female adolescents are significantly different.At the relationship scope level,both two scopes of friends have significant positive influences on the physical inactivity of adolescents.On the closeness level,however,the influences of friendship closeness and mother closeness on the behavior of male and female adolescents have changed dramatically.Furthermore,this study uses the spread of unhealthy dietary behaviors among adolescents as a sensitivity analysis,which further reveals the influence of three social relationship factors on individual behaviors.Third,this study established a socialized spreading model for two competing health behaviors,constructed the role of peer influence in three perspectives,and emphasized the long-term effects of spouses on individual health behaviors.We studied the spouse influence on individual health behaviors from three aspects,that is,the similarities of health behaviors between individuals and their spouses,the spouse influence on individual’s health behavior change,and the spouse influence on whether the individual’s health behaviors meet the WHO recommended standards.The results showed that behavior similarity between individual and the spouse is significantly existed.And the spouse can also help the individual to make a behavior change.Moreover,WHO standard is often the baseline of individual health.The spouse can prompt the individual to achive the standard.However,this prompting effect is temporally limited.Fourth,this study defined individual’s passive health behavior,established the interaction effects model of passive smoking and household polluted energy use on individual health,emphasized the additive effects of them on women’s hypertension.Using smoking behavior of parents and spouse to describe women’s passive smoking behavior,this paper adopted univariate,multivariate and interactive logistic models to study the effects of passive smoking and pollution energy use on the hypertension of non-smoking women.The effects of two kinds of pollution intensity on women’s health were further analyzed.The results showed that passive smoking and household pollution energy use have significant positive effects on female hypertension,and their effects are additive.Through further research on passive smoking intensity,the results showed that the heavy passive smoking has a significant positive effect on hypertension,while light passive smoking has no significant effect on hypertension.
