“…Informed by analysis of human 24-hour food recall data from the US National Health and Nutrition Examination Survey, in which we showed that the strongest behavioural correlate of food insecurity is higher variance in the time intervals between food consumption events (Nettle & Bateson, 2019), we operationalised food insecurity as the existence of variable time intervals between periods of food availability. Additionally, because the questionnaires for measuring human food insecurity include items that probe anxiety about perceived future food availability (Saint Ville et al, 2019), we programmed the variance in the inter-food access interval such that it was unpredictable to the birds. Therefore, our operationalisation of food insecurity combined restricted access to food with variability and unpredictability in the intervals between periods of access.…”

Food insecurity—defined as limited or unpredictable access to nutritionally adequate food—is associated with higher body mass in humans and birds. It is widely assumed that food insecurity-induced fattening is caused by increased food consumption, but there is little evidence supporting this in any species. We developed a novel technology for measuring foraging, food intake and body mass in small groups of aviary-housed European starlings (Sturnus vulgaris). Across four exploratory experiments, we demonstrate that birds responded to 1–2 weeks of food insecurity by increasing their body mass despite eating less. Food-insecure birds therefore increased their energetic efficiency, calculated as the body mass maintained per unit of food consumed. Mass gain was greater in birds that were lighter at baseline and in birds that faced greater competition for access to food. Whilst there was variation between experiments in mass gain and food consumption under food insecurity, energetic efficiency always increased. Bomb calorimetry of guano showed reduced energy density under food insecurity, suggesting that the energy assimilated from food increased. Behavioural observations of roosting showed inconsistent evidence for reduced physical activity under food insecurity. Increased energetic efficiency continued for 1–2 weeks after food security was reinstated, indicating an asymmetry in the speed of the response to food insecurity and the recovery from it. Future work to understand the mechanisms underlying food insecurity-induced mass gain should focus on the biological changes mediating increased energetic efficiency rather than increased energy consumption.

“…Several studies have assessed the validity of FIES and concluded that it is the only internationally comparable measure of micro-level food insecurity that has internal and construct validity. 32 We recoded responses across the eight questions into two binary categories of food insecurity: moderate-severe food insecurity, capturing a yes response to at least four questions; and severe food insecurity, capturing yes responses to at least seven questions. 33 Our trade policy measure was a subcomponent of the Konjunkturforschungsstelle (KOF) Globalisation Index.…”

Summary Background Eradicating food insecurity is necessary for achieving global health goals. Liberal trade policies might increase food supplies but how these policies influence individual-level food insecurity remains uncertain. We aimed to assess the association between liberal trade policies and food insecurity at the individual level, and whether this association varies across country-income and household-income groups. Methods For this observational analysis, we combined individual-level data from the Food and Agricultural Organization of the UN with a country-level trade policy index from the Konjunkturforschungsstelle Swiss Economic Institute. We examined the association between a country's trade policy score and the probability of individuals reporting moderate-severe or severe food insecurity using regression models and algorithmic weighting procedures. We controlled for multiple covariates, including gross domestic product, democratisation level, and population size. Additionally, we examined heterogeneity by country and household income. Results Our sample comprised 460 102 individuals in 132 countries for the period of 2014–17. Liberal trade policy was not significantly associated with moderate-severe or severe food insecurity after covariate adjustment. However, among households in high-income countries with incomes higher than US$25 430 per person per year (adjusted for purchasing power parity), a unit increase in the trade policy index (more liberal) corresponded to a 0·07% (95% CI −0·10 to −0·04) reduction in the predicted probability of reporting moderate-severe food insecurity. Among households in the lowest income decile (<$450 per person per year) in low-income countries, a unit increase in the trade policy index was associated with a 0·35% (0·06 to 0·60) increase in the predicted probability of reporting moderate-severe food insecurity. Interpretation The relationship between liberal trade policy and food insecurity varied across countries and households. Liberal trade policy was predominantly associated with lower food insecurity in high-income countries but corresponded to increased food insecurity among the world's poorest households in low-income countries.

“…The concept of Food Insecurity Experience Scales (FIES) has a long history grounded in ethnographic studies. Their purpose is to understand the experience of hunger (Ballard, Kepple, and Cafiero, 2013;Saint Ville, Po, Sen, Bui, and Melgar-Quiñonez, 2019). Ethnographic research conducted in the USA at the beginning of the 1990s revealed that experiencing FI is a process characterized initially by worry about having enough food, followed by dietary changes to make limited food resources last longer, and finally, reduced consumption of food (Radimer, Olson, and Campbell, 1990;Radimer, Olson, Greene, Campbell, and Habicht, 1992).…”

“…Other studies regarding various populations around the world have confirmed that these aspects of food insecurity appear to be common across countries. Over time, experience-based food insecurity scales have been developed for different cultural contexts, for example since 1995 the United States Household Food Security Survey Module, and since 2007 the Latin American and Caribbean Food Security Scale have been used in several countries in North and South America (Saint Ville et al, 2019). Building on the experiences of these scales, FAO developed a scale called the Food Insecurity Experience Scale (FIES).…”

The relationship between food insecurity and objective and subjective income indicators in Poland

The study analyses food insecurity in Poland on the basis of data from the Food and Agriculture Organization of the United Nations. This data assesses the scale of experiencing food insecurity by the respondents. It includes information obtained during 2014-2019 from 6080 people. The dependence of food insecurity on the subjective and objective income situation of individuals was examined. Typical methods of analysis were used, such as Pearson's χ 2 test, Cramer V and Kendall τ b measures, and the logit model. It was found that the perception of food insecurity depends more on the subjective rather than objective income situation.
