Prevalence and Correlates of Food Insecurity in Latino Farm Worker Households in California's Central Valley

Abstract

Abstract Objectives The twofold objective of the study was to assess the burden of food insecurity in Latino farm worker households and to identify its correlates in this population. Methods We conducted a secondary analysis using data from the Mexican Immigration to California: Agricultural Safety and Acculturation (MICASA) study, a cohort of Latino farm workers residing in Mendota, California. Interview data from a follow up assessment (when food security was first assessed), and clinical data from a sub-study conducted around the same time were analyzed. Food security was assessed using the U.S. Household Food Security Survey Module: Six-Item Short Form, but only asked to female participants (n = 346). Body mass index (BMI; kg/m2) was measured based on direct weight and height measurements. Abdominal fat was categorized as normal vs high risk (waist circumference >35 inches). Blood pressure was assessed based on two consecutive measures of systolic and diastolic blood pressure, and categorized as normal, elevated or high blood pressure. Depression was measured using a short version of the CES-D scale; a score of ≥10 was used as indication of depressive symptoms. Sociodemographic and acculturation data were also collected. We conducted bivariate analysis and multivariable logistic regression, considering the study survey design. Results Fifty five % of respondents were food secure, while 45% reported food insecurity (39% without hunger and 6% with hunger). In bivariate analysis, food insecurity was associated with income, education, age at immigration, depressive symptoms and season, but not with age, years living in the US, BMI status, blood pressure or abdominal fat. After controlling for income, education and season, those who immigrated younger than 21 y of age had lower odds of reporting food insecurity, while food insecurity was associated with higher odds of depressive symptoms. Conclusions Food insecurity is prevalent among Latino farm worker families. Among women in these families, immigration to US at a younger age seems to protect them from suffering food insecurity, but experiencing it may be associated with poor mental health.
