Food insecurity and participation in community food programs among low-income Toronto families.


Kirkpatrick, Sharon I. ; Tarasuk, Valerie


Almost 1 in 10 Canadian households experienced food insecurity in 2004. (1) In addition to compromising nutrition, (2-4) household food insecurity is associated with poorer physical, mental, and social health. (5-7) While the existing research suggests that problems of household food insecurity are primarily rooted in inadequate incomes, (1,5-8) few policy directions have been proposed to address factors that constrain food purchasing. Instead, responses have generally been community-based initiatives focused on food and food-related behaviours, including food banks, meal and snack programs for children, and community kitchens and gardens. We undertook a study of low-income families residing in high-poverty Toronto neighbourhoods, employing survey methods, mapping of neighbourhood food access, and qualitative interviewing, to gain an understanding of factors that influence household food security. In this paper, we draw upon the survey and mapping data to examine household food security, participation in community food programs, and resource augmentation strategies employed when running out of food or money for food. A comprehensive examination of the relation between housing affordability, housing subsidies, social assistance, and household food insecurity will be published elsewhere.

METHODS

Sample and data collection

Data collection was completed between November 2005 and January 2007 in 12 census tracts randomly chosen from 23 high-poverty tracts in Toronto. (9) Families with children and who were tenants were studied because of the association between these household characteristics and food insecurity. (1,5,6) Potential respondents residing in rental units in each census tract were approached at the door and screened for inclusion by trained interviewers with personal experience of low income. Tenant families were deemed eligible if their gross household income was at or below the mid-level of Statistics Canada's five-category income adequacy scale. (10) These thresholds, which are slightly higher than Statistics Canada's Low Income Cut-Offs (11) and considerably higher than social assistance rates in Ontario, (12) were selected to ensure that the sample encompassed both the 'working poor' and social assistance recipients. Participation was voluntary and confidential, and the study protocol was approved by the Human Subjects Research Ethics Board at the University of Toronto.

Respondents from 501 families were surveyed, reflecting a participation rate of 62%. Seventeen families had incomes exceeding the eligibility threshold based on the detailed data collected in the survey and were excluded, resulting in an analytic sample of 484 families. Household food security over the previous 12 months was assessed using the Household Food Security Survey Module (13) and a three-level categorical variable was constructed using thresholds developed by Health Canada. (1) Moderately food-insecure families are characterized by compromises in the quality and/or quantity of food consumed by adults and/or children, whereas severely food-insecure families are characterized by reduced food intake and disrupted eating patterns among adults and/or children. Families in which neither adults nor children were characterized as moderately or severely food insecure are categorized as food secure. Questions were posed on the use of food banks and community kitchens and gardens over the previous 12 months and on children's participation in meal or snack programs at schools or community agencies over the previous 30 days. Resource augmentation strategies employed in the previous 12 months in response to threats of food shortages were captured through questions on delaying the payment of rent or bills, terminating services, pawning or selling possessions, and sending children to a friend's or relative's home for a meal. (3,14) Data on the location of community food programs were obtained from program providers and mapped using Geographic Information Systems software. Variables were then derived to indicate the distance from the dwelling of each family surveyed to the nearest food bank, community kitchen, and community garden.

Statistical methods

Analyses were performed using SAS, version 9.1.3 (SAS Institute, Cary, NC), utilizing SURVEY procedures to account for the clustering in the sampling design. Multivariate logistic regression was used to assess associations between socio-demographic characteristics and household food security status, utilizing severe food insecurity as the predicted outcome because of the highly vulnerable nature of the sample. Logistic regression was also used to examine predictors of program participation and use of resource augmentation strategies. Frequency of food bank use was examined to explore the hypothesis that regular use of charitable food assistance may be a means by which some families maintain food security. The examination of children's participation in food programs over the previous 30 days was restricted to a subsample (n=345) of families that included school-aged children (ages 5-18 years) and excluded those for whom the 30-day recall period corresponded to the summer months.

RESULTS

The sample characteristics in relation to household food security status are outlined in Table 1. Over one third of families (37.6%) were moderately food insecure and over one quarter (27.7%) were severely food insecure over the previous 12 months. Severe food insecurity was negatively associated with household income whereas households reliant on social assistance, those headed by a lone mother, and those in which the respondent had not completed high school had greater odds of severe food insecurity (Table 2).

About one in five families used food banks in the previous 12 months (Table 3). Moderately food-insecure families had two times higher odds (OR = 2.18, 95% CI = 1.17-4.07) and severely food-insecure families had six times higher odds (OR = 6.41, 95% CI = 3.75-10.97) of using a food bank at least one time in the previous year compared to food-secure families. Food bank use was positively associated with reliance on social assistance or other government transfers and the respondent having less than a high school education; lower odds of food bank use were observed with increasing income and among immigrants (data not shown). Among families that used food banks, use was relatively infrequent with over half (56.7%) reporting use in 3 or fewer of the previous 12 months and less than one fifth (19.2%) reporting use in 10 or more months. Only 4.1% of all families used a food bank in 10 or more of the previous 12 months (1.2% of food-secure families, 5.0% of moderately food-insecure families, and 6.7% of severely food-insecure families). Regular food bank use was positively associated with reliance on social assistance (data not shown). The distance from each family's dwelling to the nearest food bank was not associated with whether a family used a food bank at all nor with regular food bank use (data not shown). Rates of participation in community kitchens and gardens were very low (Table 3), precluding an examination of predictors of participation.

One third (33.6%) of families with school-aged children reported participation in children's food programs at schools or community agencies in the previous 30 days, with snack programs being most frequently used (Table 3). The majority of children (68.1%) who participated in programs attended regularly (at least 20 of the previous 30 days). Families paid a program fee for most children (76.2%) who participated regularly: the median cost per child per program over the previous 30 days was $4 (range $0-100). There were no significant associations between regular participation in children's food programs and household food security status nor household socio-demographic characteristics (data not shown); using a less stringent threshold of 15 days to denote regular participation did not change these findings. Associations between participation and geographic proximity of programs were not assessed since our data did not permit us to identify the schools that children attended.

Among the resource augmentation strategies examined, delaying payment of bills in response to threats of food shortages was most commonly used (Table 4). Moderately and severely food-insecure families were significantly more likely than food-secure families to delay payments of bills or rent, sell or pawn personal possessions, and terminate services (Table 5). The low rates of usage of some strategies among food-secure families resulted in wide confidence intervals for some odds ratios, but the pattern appears to be towards increasing use of strategies with worsening food insecurity. The odds of sending children to a friend's or relative's home for a meal according to food security status were not computed since this strategy was used exclusively by food-insecure families (Table 4).

DISCUSSION

Among this sample, the prevalence of food insecurity was more than double the observed prevalence among households in the lowest three income adequacy categories nationally in 2004, (1) highlighting the clustering of problems of food insecurity in high-poverty neighbourhoods. Even among this highly vulnerable subgroup though, severe food insecurity was associated with the same risk factors repeatedly identified in national surveys--i.e., declining income, reliance on social assistance, and living in a lone-mother household. (1,5-8)

To date, the primary responses to household food insecurity have been local-level food-based initiatives, predominantly food banks, (15,16) but also school- and community-based meal and snack programs for children (17-22) and programs such as community kitchens and gardens aimed at enhancing food skills and food access. (23-26) While it has long been recognized that such initiatives do not address the economic issues that underlie food insecurity, (15,16,27-29) the perception that these programs play a valuable role in addressing the unmet food needs of food-insecure children and/or households persists.30 Our data challenge this perception. Not only were rates of program participation surprisingly low--never exceeding one third of our sample--but we found no indications that the use of food banks or children's food programs had any bearing on household food security status. The patterns of food bank use among this sample suggest that it is a strategy of desperation, not a means of routine food acquisition. Participation rates were so low that we could not even analyze the relationship between community garden or kitchen participation and household food insecurity. These low participation rates were documented among a predominantly food-insecure sample of families living in neighbourhoods with ample access to such programs. Our results highlight the need for systematic evaluations of community food initiatives to determine their relevance and accessibility for food-insecure households.

We are unable to assess whether the program participation rates observed in this study differ from those of food-insecure households in other jurisdictions. However, the relationships observed between usage of community food programs and household food insecurity are consistent with previous research. Data from the 1996-97 and 1998-99 cycles of the National Population Health Survey indicated that only 20-35% of households characterized as food insufficient or food insecure reported receiving food charity over the previous year. (5,6) Food bank statistics also show numbers that are far lower than those captured in national food insecurity prevalence estimates. (31) The apparent lack of a protective effect of food bank use observed in the current study has also been previously documented, with our research on food bank users in Toronto revealing no association between frequency of food bank use and severity of household food insecurity. (32) Studies of children's food programs and community kitchens have also raised questions about their capacity to address problems of food insecurity due to factors such as limited scope and inability to address the food needs of those living in severe poverty. (15,18,19,22,24,33-37)

While rates of program participation were low, the use of other resource augmentation strategies such as delaying payments of bills or rent and the termination of telephone and other services was relatively common. This is worrisome given that such strategies can only compound the vulnerability of food-insecure families by causing them to incur debts, risk eviction, exhaust social support networks and become more socially isolated.

The high prevalence of food problems among this sample coupled with low levels of participation in community-based programs and the common use of other resource augmentation strategies highlight the need for more effective responses to household food insecurity in Canada. While community-based programs currently form the mainstay of responses, our research provides evidence that these initiatives are reaching only a small proportion of those in need and are unable to compensate for the inadequacy of their household incomes. Our findings point to the need for a critical examination of these programs to ensure that they are structured to provide the maximum benefit possible to the most vulnerable members of our communities. There is also a need for advocacy for policy reforms to ensure that low-income households have adequate resources for food.

* The examination of children's participation in food programs over
the previous 30 days was conducted among a subsample (n=345) of
families that included school-aged children (ages 5-18 years) and
excluded those for whom the 30-day recall period corresponded to the
summer months.
