Food Insecurity Is Associated with Subjective Well-Being among Individuals from 138 Countries in the 2014 Gallup World Poll.

Food insecurity is an aspect of living conditions that is particularly important for quality of life, health, and subjective well-being. The implementation of the 8-item Food Insecurity Experience Scale in 147 countries in the 2014 Gallup World Poll provided an unprecedented opportunity to understand the association of food insecurity with subjective well-being. We examined how food insecurity relates with measures of living conditions and how food insecurity and other living conditions relate with physical health and, in turn, subjective well-being. Data were collected from individuals aged ≥15 y by telephone in 38 countries and via face-to-face interviews in 111 others. The available sample was 132,618 (138 countries) and 122,137 (137 countries) for the daily experience and life evaluation indexes of subjective well-being, respectively. Daily experience was a continuous measure and life evaluation was categorized into thriving, struggling, and suffering. We estimated 6 linear or logistic regression models for each index controlling for country as a fixed effect. Food insecurity was associated with the other 3 measures of living conditions: household income, shelter and housing, and employment. Food insecurity explained poor physical health and lower subjective well-being beyond other measures of living conditions. Instrumental and emotional support was associated with higher subjective well-being. The associations of food insecurity with subjective well-being were larger than with other explanatory variables. Food insecurity was associated with subjective well-being within each of the 4 World Bank income classes of countries, with a larger magnitude of differences for the higher-income classes. Food insecurity was strongly and negatively associated with subjective well-being in a large global sample of individuals aged ≥15 y. These results demonstrate the consistency of goal 2 of the Sustainable Development Goals, which has targeted 2030 to ensure food security for all people, year-round, with other goals to reduce food insecurity.
