Pain has grown more prevalent in high-income countries, including Canada and the United States, where 1 in 5 people report having chronic pain. 1,2 Lack of pain clinics and long wait times have forced many to selfmedicate -sometimes with illicit drugs -and to seek care at an emergency department. 3 Abdominal and pelvic pain, pain in the throat and chest, and dorsalgia are among the most common causes of emergency department visits in Canada, jointly accounting for one-tenth of all visits. 4 Pain may reduce quality of life and trigger or exacerbate substance abuse, anxiety and depression, 5,6 precipitating suicide in extreme cases. 7 Service delays and undertreatment at emergency departments are believed to contribute to risky self-medication by patients with pain. 8 In the context of a health care system, poorly managed pain has been associated with increased health care utilization and costs. 9 Food insecurity -inadequate or insecure access to food because of financial constraints -is a serious problem in Canada. 10 The ongoing COVID-19 pandemic further aggravated the issue. 11,12 As a well-established social determinant of health, food insecurity has been associated with multiple negative health outcomes, including mental disorders, substance use and suicide. [13][14][15][16][17][18] Population research connecting food insecurity and pain is rare. As a notable exception, food insecurity has been associated with self-reported chronic pain among Canadian adults and adolescents in a graded fashion. 19 Two other cross-sectional studies have associated food insecurity with self-reported migraine among Canadians and young adults in the US. 20,21 A higher prevalence of pain has been documented among lower income and less educated populations, [22][23][24] but those indicators do not necessarily capture food insecurity and its associated health hazards.
