The phenomenon of intergenerational care of the elderly has a certain universality。In the world，Although Western culture emphasizes individual independence，Oriental culture is mainly family stickiness，But the intergenerational care is a common social phenomenon。As early as 1998，43%of the grandmother in the United States regularly provide a certain degree of care for grandchildren。European scholar HANK's survey in 2008 also discovered，Elderly people with more than half of Europe participated in the intergenerational care。In our country，2015 "China Physical and mental Health and Pension Tracking Survey" report display，The proportion of the elderly participating in the intergenerational care of the country has reached 53%。With the implementation of the "two -child" policy in my country，This ratio will continue to rise。

Current，The theory of the next generation of care affects the physical and mental health of the elderly，The earliest dates back to the "role tension theory" proposed by Goode in the 1960s。This theory thinks，Individuals take different roles in society，The difference between the requirements between characters makes the individual face different problems，At the same time, occupying different personal resources。Scholars with negative views support this theory，They believe that the time of intergenerational care not only occupies the time for the elderly to maintain their health Bet365 lotto review and learn new things，and may cause more serious physical and mental health risks。

After the 1970s，Sieber (Sieber) proposed the opposite "role improvement theory"。This theory emphasizes the resources and emotional income obtained by individuals in the role of individuals in society，It is believed that income can offset the "role tension" state caused by multiple character conflicts。This theory is in line with the views of a scholar with a positive attitude，They believe that the intergenerational care is conducive to the physiological health of the elderly，It also gives the elderly a new role，Through interaction with grandchildren, it is more helpful to fight depression mood，Make it more vitality。

How does the intergenerational care affect the physical and mental health of the elderly，At present, the empirical research at home and abroad is rich，But the conclusion obtained is not consistent。According to the conclusion of existing research，It can summarize relevant research from the physiological and psychological aspects to two types: positive impact and negative impact。

One is a positive impact。Current，Research on the positive impact of the intergenerational care is mainly concentrated in China。In terms of physiological health，Intergenerational care promotes the behavior activities of the elderly，helps improve its physiological health status。Just like Song Lu、Zhou Jing et al.，Compared to the elderly who do not take care of their grandchildren，Take care of the elderly health advantages of the elderly people who are more obvious。Wu Peicai found that participating in exercise is one of the mechanisms that activate the physiological and healthy status of the bet365 live casino games elderly，is accompanied by the intergenerational care behavior，The possibility of the elderly participating in exercise has increased。Studies from foreign scholars Baydar and Brooks and others also pointed out，Regular care of the elderly of the grandchildren has a better physical health level，They are more inclined to report without daily activity disorders (such as eating、Bath、Dress、Danity、Get out of bed and walk, etc.)。

In terms of mental health，The positive impact of intergenerational care is mainly reflected in the reduction of the depression state of the elderly and the improvement of life satisfaction。in the country，Library (KU) and others' research results on the elderly in Taiwan, China, indicate that，Compared with the elderly who do not take care of the grandchildren，The elderly who provided the elderly who provided the grandson had less depression，better mental health。Huang Guogui、Song Liangzhang's research on the data of "China Society Tracking Survey in China" in 2014 also confirmed，Delicate care behavior is significantly negatively related to the depression of the elderly。and foreign scholar Grandy、Kim (Kim) and others' research also discovered the same，Compared to the elderly who do not provide intergenerational care，Care with the grandson's elderly who are less depressed。other，Xiao Haixiang、Wang Ari’s research also found，Interaction with the grandchildren can improve the satisfaction of the elderly。As the research institute of Goodfellow pointed out，The elderly "" in the process of taking care of the grandchildren，enriched and enriched its old age，Make yourself exert the bet365 Play online games effect of teaching the new generation "。other，Wang Ari、The study of Wu Peicai also expressed，Provide intergenerational care will improve its mental health by increasing the frequency of the elderly to participate in social activities。

The second is negative effects。Current，Research on the negative impact on the intergenerational care is mainly concentrated abroad。In terms of physiological health，Research discovery of Musil and Ahmad，Compared with the elderly who do not provide intergenerational care，The number of times the person who provides caregivers is more frequent。Baker and Silverstein also pointed out，Provide care will increase the health burden of the elderly，Squeezing the time for exercise and medical treatment。and the specific to the chronic disease，Lee (Lee) et al.，Compared to the elderly who do not take care of the grandson，Take care of the grandson's self -rated health scores lower，Report the Coronary arteries、Hypertension、The probability of high cholesterol or physical pain is greater than the probability of more than the body pain。Domestic scholar Xiao Yaqin、Huang Guogui's research also found，Care will have a trend of worsening the health (self -assessment) of the elderly (self -assessment) and the ability of daily activities。

In terms of mental health，Intergenerational care may increase the depression risk of the elderly。Hughes and others' research discovery，The elderly who provide intergenerational care are higher than the depression without providers。Minkler、Spencer、Doley et al.，The daily activities of the elderly who provide intergenerational care are mainly around the family，Easy to produce boredom，and take care bet365 best casino games of the responsibility of the grandchildren will also bring mental stress to the elderly，Not conducive to its mental health。Research by domestic scholar Xiao Yaqin and others also pointed out，The depression level score of providing intergenerational caregivers is slightly higher than non -providing people，It may increase the depression risk of the elderly。

Regardless of theory or empirical research，The impact of intergenerational care on the physical and mental health of the elderly shows two sides of positive and negatively coexisting。Reasons for the reason，Perhaps it is related to whether the intensity of care is appropriate。Chen (Chen) and Liu (liu) research representations，Low -intensity care has a protective effect on the physical and mental health of the elderly。The study of Mingkeler pointed out，Take the care time of 30 hours per week as the boundary，Beyond this time，The disability rate of the daily activities of the elderly may increase。Research on Wu Peicai also found，When the elderly take care of the past year for more than 3 months，The positive impact of intergenerational care on its physical and mental health still exists，But the degree has declined。COALL research discovery，The intensity of the intergenerational care and physical and mental health of the elderly is a non -linear relationship。The research of Han Baoqing and Wang Shengjin further display，The effects of taking care of the grandchildren on the physical and mental health of the elderly. With the increase of the intensity of care, it shows a pour -U -shaped relationship with the disadvantages of the first profit。

To sum up，We can find research on the influence of the elderly's physical and mental health，Including bet365 live casino games two effects: "role tension" and "role improvement"，Difficult to divide Bo Zhong。In empirical research，There are many foreign research and more negative impact，Domestic research is relatively small but mainly based on positive influence，This may be related to the differences in the cultural differences of the East and the West。The intensity of intergenerational care is a key variable，Increase with the intensity of care，The positive efficiency generated by the intergenerational care will decrease or disappear。

2002，The World Health Organization proposed "Health、Participate、Guarantee "is the active aging theory of the pillar。In this background，It should be promoted to promote the social participation of the elderly。In our country，Intergenerational care is an important and common expression of social participation of the elderly。So，The government wants to advocate、Encourage the appropriate intergenerational care behavior of the elderly，In order to play a positive role in promoting the physical and mental health of the elderly; make full use of public places in urban and rural communities，Carry out "New Knowledge Lecture"，Help the elderly group to better participate in the care of the grandchildren; affirm the value of the elderly's intergenerational care，Give certain policy support (such as improving social security level or establishing special subsidies, etc.)。
