16、cial networking"One of the most pronounced changes in the daily habits of British citizens is a reduction in tfe number of minutes per day that they interact with another human being. Recent history has seen people in marked retreat from one another as Britain moves from a culture of greater co

18、important matters nearly tripled”.The number of both kin and non-kin confidants is described as "dramlatically smaller”(McPherson，Smith-Loven, Brashears, 2006). A 2003 report by the UK's Office for National Statistics (Ruston, 2003)found that Britons now spent approximately 50 minutes a day

19、 interacting socially with other people. Couples now spend less time in one another's company and more time at work, commuting, or in the same house but in separate rooms using different electronic media devices. Parents spend less time with their children than they did only a decade ago. Britai

20、n has the lowest proportion of chil山en in all of Europe who eat with their parents at the taLle. The proportion of people who work on their own at home continues to rise. The report went on to say that in the 20 years to 2003, "the proportion of people living alone doubled:- a trend highly pron

The amount of face-to-face social interaction declines as use of electronic media increases. These trends are predicted to increase (data

26、rmouts increase in "social networrking" among younger children which had overtaken fun (online games) as the main reason to use the Internet. Time that was previously spent interacting socially has increasingly been displaced by the virtual variety. A 2008 editorial in the .l ourna o f the

27、 Roycel Socie。)o f Medicine (Abbasi，2008) made the timely point that social networking”encourages us to ignore the social networks that form in our non-virtual communities”,and argued that”the time we spend socialising electronically separates us from our physical networks”. But why precisely should

28、 physicians be concerned about these changes in peoples actual contact and interaction with one another? One reason is that social connection is increasingly associated with physiological changes known to influnce both morbidity (the incidence of disease in the population) and mortality (the death r

29、ate).MorbidityAccording to the Oxford English Dictionary morbidity refers to”the rate of disease, or a specific disease，in a population”. Several decades of research have found that greater social contact is related to reduced morbidity while fewe:contacts lead to increased morbidity. This relations

30、hip is valid independent of the individuals earlier health status.Rutledge et al. (2008) reported that women with fewer social relationships experienced strokes at more than twice the rate of those with more social relationships after adjusting for other possible medical reasons for strokes,A furthe

31、r study on strokes, involving experiments on male and female mice，reported that social interaction reduced concentrations of a protein linkeu with strokes, and decreased theamount of damage to body tissue caused by the inflow of blood during a stroke.Loneliness is found to be a unique predictor of a

32、ge-related differences in blood pressure when the heart is pumping blood. And blood pressure for married adults-especially those happily married-declines more during sleep than for single people who may therefore be at much greater risk of problems with the heart and blood vessels，In one experiment,

33、 in which men were challenged in order to increase their blood pressure，it was found that blood pressure returned to baseline levels more quickly in the men with more close friends.The incidence of senile dementia (Alzheimer's disease)-serious mental disorder in older people-is expected to doubl

The study concluded that the rate of me

35、mory loss among the least-integrated was twice the rate of loss among the most-integrated. Others report that the frequency of social interaction is inversely related to the incidence of dementia and may protect against dementia.A positive relationship between the sheer amount of regular actual soci

36、al contact and cognitive functioning has,however, been found in a variety of age groups including younger adults. Most interesting is the study byYbarra et al. (2008) in which participants who interacted socially for. only 10 minutes Showed improved cognitive performance, performance equivalent to t

37、hat displayed by partcipants engaged in so-called intellectual activities, The authors believe the results show not only that the effect is causal but also that the process is very sensitive to only small amounts of social interaction. They conclude: "Social interaction directly affects memory

38、and mental performance in a positive way.”Marriage and cohabitationRuston(2003)reports that the long-recognised protective effect of marriage against suicide has persisted over the past 25 years，despite changes in marriage patterns. Between 1983 and 2004，suicide rates for single people were around t

39、hree times higher than for married people. For single women，the differential compared with married women widened from just over two times to three times.Unfortunately, our marriage rate is at an all-time low.Statistics indicate that the protective effects conferred by marriage are cumulative, as are

40、 the harmful effects of years being divorced (Lund et al., 2006).Conclusionwhile the precise mechanisms underlying the association between social connection, morbidity and mortality continue to be investigated，it is clear that this is a growing public health issue for all industrialised countries.Kr
