abstract
Background: Evidence on the differential impacts of the global food crisis as it locally translates into chronic food insecurity is essential to design food security interventions targeting the most vulnerable groups. There are no studies on the extent of chronic food insecurity or its predictors among adolescents. In the context of increased cost of food prices in Ethiopia, we hypothesized that adolescents in the low income urban households are more likely to suffer from chronic food insecurity than those in the rural areas who may have direct access to agricultural products. Methods: This report is based on data from the first two rounds of the Jimma Longitudinal Family Survey of Youth (JLFSY). Both adolescents and households were selected using a stratified random sampling method. A total of 1911 adolescents aged 13-17 years were interviewed on their personal experiences of food insecurity both at baseline and year two. Multivariable logistic regression analyses were used to compare chronic adolescent food insecurity by household income, household food insecurity and socio-demographic variables after one year of follow-up. Results: Overall 20.5% of adolescents were food insecure in the first round survey, while the proportion of adolescents with food insecurity increased to 48.4% in the second round of the survey one year later. During the one year follow up period, more than half (54.8%) of the youth encountered transient food insecurity that is either during the first or second round survey. During the follow up period 14.0% of adolescents had chronic food insecurity. Multivariable logistic regression analysis showed that adolescents in the urban households with low (OR=1.69, P=0.008) and middle (OR=1.80, P=0.003) income tertiles were nearly twice as likely to suffer from chronic food insecurity compared with those in high income tertile, while this was not the case in rural and semi-urban households. Female sex of adolescents (P<0.01), higher dependency ratio (P<0.05) and household food insecurity (P<0.001) were independent predictors of chronic adolescent food insecurity in all residence places, while educational status of the adolescents was negatively associated with chronic food insecurity (OR= 0.047, P=0.002) in urban areas. Conclusions: In the context of increased food prices, household income is an independent predictor of chronic food insecurity only among adolescents in the urban low income households. Female gender, educational status of primary or less and being a member of households with high dependency ratio are independent predictors of chronic food insecurity in all places of residences. The fact that the prevalence of chronic food insecurity increased among adolescents who are members of chronically food insecure urban households as income tertiles decreased suggests that the resilience of buffering is eroded when purchasing power diminishes and food resources are dwindling. Food security interventions should target urban low income households to reduce the level of chronic food insecurity.
