The study also found that people from Western Europe and North America are more likely to suffer from anxiety than people from other cultures.
Researchers from University of Cambridge in the UK highlighted how anxiety disorders often provide a double burden on people experiencing other health-related problems, such as heart disease, cancer and even pregnancy.
Out of over 1,200 reviews, researchers identified 48 reviews that matched their criteria for inclusion.
The highest proportion of people with anxiety is in North America, where almost eight out of every 100 people are affected; the proportion is lowest in East Asia, where less than three in 100 people have this mental health problem, researchers said.

Women are almost twice as likely to be affected as men, and young individuals - both male and female - under 35 years of age are disproportionately affected, they said.
Researchers also found that people with other health conditions are often far more likely to also experience anxiety disorders.
People living with multiple sclerosis are most affected - as many as one in three patients (32 per cent) also have an anxiety disorder, they said.
"By collecting all these data together, we see that these disorders are common across all groups, but women and young people are disproportionately affected," said Olivia Remes from University of Cambridge.
"Also, people who have a chronic health condition are at a particular risk, adding a double burden on their lives," said Remes.
In the general population, only one in a hundred people are affected by OCD, but the proportion with the disorder was double in pregnant women and slightly higher in post-partum women.
"Anxiety disorders affect a lot of people and can lead to impairment, disability, and risk of suicide," said Louise Lafortune from Cambridge.
The findings were published in the journal Brain and Behaviour.
