People who have low fruit and vegetable intakes have a higher likelihood of being diagnosed with an anxiety disorder, say, researchers. The study, published in the International Journal of Environmental Research and Public Health, found that those who consumed less than three sources of fruits and vegetables daily, there were at least 24 percent higher odds of anxiety disorder diagnosis.
“This may also partly explain the findings associated with body composition measures. As levels of total body fat increased beyond 36 percent, the likelihood of anxiety disorder was increased by more than 70 percent,” said co-author Jose Mora-Almanza, a Mitacs Globalink intern who worked with the study at Kwantlen Polytechnic University in Canada.
According to the researchers, increased body fat may be linked to greater inflammation. Emerging research suggests that some anxiety disorders can be linked to inflammation.
“Our findings are in keeping with previous research which has also indicated that women are more vulnerable to anxiety disorders than men,” said study co-author Karen Kobayashi.
The study team analyzed data from the Canadian Longitudinal Study on Aging which included 26,991 men and women between the ages of 45 and 85. Other factors associated with anxiety disorders among mid-age and older Canadians
In addition to diet and body composition measures, the prevalence of anxiety disorders also differed by gender, marital status, income, immigrant status, and several health issues.
One in nine women had an anxiety disorder compared to one in fifteen men, the study said.
The prevalence of anxiety disorders among those who had always been single (13.9%) was much higher than among those who were living with a partner (7.8%).
Approximately one in five respondents with household incomes under R308 621 per year had anxiety disorders, more than double the prevalence of their richer peers.
“We were not surprised to find that those in poverty had such a high prevalence of anxiety disorders; struggling to afford basics such as food and housing causes relentless stress and is inherently anxiety-inducing,” said study co-author Hongmei Tong, Assistant Professor at MacEwan University in Canada.
