Food insecurity: A public health issue for BC

This is a revised version of the article published in the January/February 2014 issue (BCMJ 2014;56:29,46). The BC Centre for Disease Control corrected an error that appeared in the first sentence of the third paragraph in the original article (“Food security” corrected to “Food insecurity”).
 


As a wealthy province with publicly funded health care and schools, employment insurance, and social security, and a reliable food supply, no British Columbian should lack access to sufficient nutritious food. Still, over 8% of BC residents experience food insecurity,[1] and food bank use is up over 20% since 2008.[2]

Food security means more than having enough to eat. Even people depending on soup kitchens may get enough food, but the food they receive is often of poor quality and low nutritional value. The Ministry of Health considers a safe, nutritious, culturally acceptable diet obtained through a just and sustainable food system to be the foundation to healthy eating.[3] Although poverty is an important risk factor, food insecurity exists where you may not expect it. New immigrants, people who lack food skills, working families, pensioners, university students, people with limited mobility, and residents of new suburban developments without neighborhood grocery stores also experience food insecurity. 

Food insecurity leads to poor health through a complex network of factors. Nutrition and living conditions in the prenatal and early childhood periods impact health throughout life[4,5] and into future generations.[4,6] Children experiencing food insecurity have poorer school performance,[7] and having not learned healthy eating habits in childhood, they face additional challenges to healthy living as adults. Food insecurity is associated with higher prevalence of diabetes[8,9] as well as cardiovascular,[8,9] dental,[10] and psychosocial9 outcomes in adults. Food-insecure women are more likely to be obese.[8,9,11] Researchers are conflicted as to whether these health conditions are caused by food security or the suite of circumstances related to socioeconomic deprivation, but the impacts on health and life course are real.[5,12,13]

Though its causes extend beyond the scope of clinical practice, physicians should consider the impact of food insecurity on patients’ health and treatment options.

Identify patients at risk 
First Nations, single-parent families, recent immigrants, and people living on disability assistance, employment insurance benefits, or social assistance are at particular risk for food insecurity.[2,14] Income in relation to living expenses, transportation to grocery stores, housing, and food literacy all affect diet quality. The Canadian Community Health Survey Household Food Security Survey Module provides 10 questions to assess the presence and severity of food insecurity.[15

Consider food insecurity in treatment plans 
Patients on limited budgets might have to choose between buying medication or food.[13] They may avoid waste by consuming foods of questionable quality or safety. Managing chronic conditions is harder for patients whose food choices are restricted by finances, mobility, or social conditions. Healthy diets—for well-being, chronic disease management, or weight loss—cost more,[16-18] and are difficult to obtain through charitable food sources.[19,20

Learn about available food security resources 
HealthLink BC and the Ministry of Health websites provide information about community-based food security programs, advice about healthy eating on a limited income, and details of provincial and federal nutrition support benefits.[21,22

The BC Centre for Disease Control and the Population and Public Health Program at the Provincial Health Services Authority are engaged in research, program and policy development, and knowledge sharing to improve access to safe and healthy food for all. In addition to their clinical practice, physicians can further support patient health by advocating for policies that improve food security in British Columbia.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
