Health needs and neighbourhood concerns of low income households vulnerable to food insecurity

The association of food insecurity and cardiometabolic risk factors was independent of body mass index in Iranian women

Background

Investigations on food insecurity have shown that food insecurity is inversely associated with health. We examined the association of food insecurity and cardiometabolic risk factors in women living in Shiraz, Iran.

Methods

The cross-sectional study was performed on 190 females. Food insecurity was assessed by Household Food Insecurity Access Scale. Cardiometabolic risk factors including anthropometric characteristics, blood pressure, and serum glucose and lipids were measured. Metabolic syndrome score was calculated according to the criteria described for Iranian adults. The association of food insecurity and cardiometabolic risk factors was assessed by linear regression.

Results

The prevalence of food security, and mild, moderate, and severe food insecurity was 42.6%, 40.5%, 15.8%, and 1.1%, respectively. Cardiometabolic risk factors worsened with increasing severity of food insecurity. Among the risk factors, body mass index (BMI) had the strongest association with food insecurity. After controlling demographic factors and BMI, fasting blood glucose, triglycerides, total, LDL, and HDL cholesterols, and metabolic syndrome score still showed significant associations with food insecurity (P < 0.01) but systolic and diastolic blood pressure were no longer associated with food insecurity after adjustment for BMI.

Conclusion

Overall, although BMI was strongly associated with food insecurity, cardiometabolic risk factors including blood glucose, triglycerides, total, HDL, and LDL cholesterols, and metabolic syndrome score were associated with food insecurity independent of BMI, suggesting that other factors such as lifestyle and diet may have contributed to the exacerbated cardiometabolic risk in food insecure participants of this study. Future studies need to clarify underlying factors in the association of food insecurity and cardiometabolic risk factors.

The impact of novel and traditional food bank approaches on food insecurity: a longitudinal study in Ottawa, Canada

Background

Food insecurity is strongly associated with poor mental and physical health, especially with chronic diseases. Food banks have become the primary long-term solution to addressing food insecurity. Traditionally, food banks provide assistance in the form of pre-packed hampers based on the food supplies on hand, such that the food items often do not meet the recipients’ cultural, religious or medical requirements. Recently, new approaches have been implemented by food banks, including choice models of food selection, additional onsite programming, and integrating food banks within Community Resource Centres.

Methods

This study examined changes in food security and physical and mental health, at four time points over 18 months at eleven food banks in Ottawa, Ontario, Canada. The participants – people who accessed these food banks – were surveyed using the Household Food Security Survey Module (HFSSM) and the Short-Form Health Survey Version 2 (SF-12). Statistical analyses included: pairwise paired t-tests between the mean perceived physical and mental health scores across the four waves of data collection, and longitudinal mixed effects regression models to understand how food security changed over time.

Results

The majority of people who were food insecure at baseline remained food insecure at the 18-month follow-up, although there was a small downward trend in the proportion of people in the severely food insecure category. Conversely, there was a small but significant increase in the mean perceived mental health score at the 18-month follow-up compared to baseline. We found significant reductions in food insecurity for people who accessed food banks that offered a Choice model of food distribution and food banks that were integrated within Community Resource Centres.

Conclusions

Food banks offer some relief of food insecurity but they don’t eliminate the problem. In this study, reductions in food insecurity were associated with food banks that offered a Choice model and those that were integrated within a Community Resource Centre. There was a slight improvement in perceived mental health at the 18-month time point; however, moderately and severely food insecure participants still had much lower perceived mental health than the general population.

Food insecurity and epilepsy in a nationally representative sample

BACKGROUND

Food insecurity amongst patients with epilepsy has not been previously studied. The aim of this study was to compare the presence of food insecurity within a nationally representative sample of individuals reporting epilepsy with that within the general population.

METHODS

The Canadian Community Health Survey, Cycle 3.1, is a cross-sectional survey that uses a stratified cluster sample design to obtain information on Canadians 12years of age or older. Data on food insecurity were compared for those who reported having epilepsy and the remainder of the population.

RESULTS

Of the 102,927 eligible survey respondents, 654 reported having epilepsy. Food insecurity was considerably more likely to be reported amongst those also reporting epilepsy with a rate of 10.8% compared with those not reporting epilepsy with a rate of 5.2% (odds ratio=2.2, (95% CI=1.6, 3.0)). Binary bivariate prediction of food insecurity within the population of respondents reporting epilepsy included the following: education, income, family size, and home ownership.

CONCLUSIONS

The experience of food insecurity appears to be more frequent amongst persons living with epilepsy. Whether this is related directly to epilepsy or factors within the epilepsy experience is unclear.
