BMJ: AREYOMLOLY?Big data tips, life is lonely!Youarenotalone!

Strong growth in human social relationships. Lonely sense is a negative, subjective experience, closely related to the quality of social relations. Loneliness is similar to social isolation, but is different from social isolation, the definition of social isolation is the lack of social contact, and loneliness means far away from social relations.

More and more evidence shows that loneliness is related to various bad health results. Loneliness is related to bad cardiovascular health indicators, such as hypothalamic-pituitary-adrenal axis activation, high blood pressure, cholesterol levels and coronary heart disease.

In order to determine the epidemics of loneliness in the global population level, experts from the Sydney University Medical and Health College Sydney Public Health Academy summarize the popularity of the World Health Organization region through meta-analysis, and the time trend of the loneliness in data. . The results were published in the recent BMJ magazine.

The research data source EMBASE, Medline, Psycinfo and Scopus retrieve peer review literature, Google Scholar and Open Grey retrieve gray literature and supplemented with reverse references. An observational study based on National Representative Sample (N ≥ 292) is included. Two researchers extracted data independently and using the Joanna Briggs Institute's inspections to evaluate bias risk.

The results show that according to the official regional nomenclature of WHO, 57 studies provide a prevalence data in 113 countries or regions. Adolescents of 77 countries or regions (12-17 years old), young age (18-29 years old), middle-aged (30-59 years old) and 40 countries in 32 countries (≥60 years old) There are data.

Overall, 24 studies have been incorporated into a meta-analysis of 212 estimates of 106 countries. Adolescent lonely collection epidemics range from 9.2% from Southeast Asia (95% CI: 6.8% -12.4%) to 14.4% (12.2% -17.1%) in eastern Mediterranean.

For adults, only the European region is met, all adult age groups show consistent geographic models. The loneliness of loneliness in Nordic countries is the lowest (2.9%, 1.8% -4.5%; middle-aged adults is 2.7%, 2.4% -3.0%; senior adults are 5.2%, 4.2% -6.5%), Eastern European countries (Young adults were 7.5%, 5.9% -9.4%; middle-aged adults were 9.6%, 7.7% -12.0%; elderly adults were 21.3%, 18.7% -24.2%).

It can be seen that in many countries, there is a considerable number of people experience a problem with loneliness. In the future, lonel sensation is included in general health monitoring, using standardized, verified measurement tools, covering a wider range of geographies and ages.
