The Impact of Natural Disasters on Dietary Intake

Abstract

Objectives: In this study, we explored the potential impact of disasters on individuals' fruit and vegetable consumption. Methods: Individual-level data (N = 351,229) from the Behavioral Risk Factor Surveillance System (BRFSS) 2011 survey were merged with county-level disaster declaration data from the Federal Emergency Management Agency (FEMA) based on disaster duration, interview month and residential county. Multilevel mixed-effects generalized linear models were conducted to examine the impact of different types of disasters on self-reported daily fruit, 100% pure fruit juice, beans, green vegetables, orange vegetables, other vegetables and overall vegetables consumption frequencies, adjusting for individual covariates. Results: No associations between disasters and daily fruit and overall vegetable consumption frequency were identified at either national or state levels. Only floods were consistently associated with reduced consumption of orange vegetables. Conclusions: This study did not identify an association between natural disasters and daily overall fruit/vegetable consumption frequency at national or state levels, whereas disasters were found to alter the consumption of certain vegetable subgroup (orange vegetables) slightly. Longitudinal studies with validated and detailed measures on diet and disaster are warranted to advance research in this field.

RETRACTED ARTICLE: Childhood obesity risk increases with increased screen time: a systematic review and dose–response meta-analysis

“…Physical inactivity is prevalent among children; on average, children spent 41% and 51% of the after-school period in sedentary time when at after-school care and other locations (e.g. participation in afterschool programs, screen-based behaviors, homework/academics or social activities and motorized transport) respectively [8][9][10].…”

Health Behaviors of Higher Education Students from 7 Countries: Poorer Sleep Quality during the COVID-19 Pandemic Predicts Higher Dietary Risk

“…While the prevalence of higher education students reporting elevated stress is high, the current COVID-19 pandemic has further increased stress for many students [22][23][24]. Previous studies demonstrated that large-scale disasters, including pandemics, led to profound health behavior changes [25,26], including unhealthy eating behaviors, poor sleep and lower physical activity levels [27][28][29][30][31][32][33]. Other studies noted increased mental health distress during disasters [34][35][36].…”

Exploring the nexus between natural disasters and food (in)security: Evidence from rural Bangladesh

“…The dependent variable used in this study is the FIES. The empirical literature has utilised several measures of food security, including food consumption (Islam & Ahmed, 2017; Maxwell et al, 2003), food production (Di Falco et al, 2011), food access (Islam & Ahmed, 2017; Islam & Al Mamun, 2020), dietary diversity (Ji et al, 2020), caloric intake (Faridi & Wadood, 2010), and food security indexes (Alam et al, 2020). However, following Sadiddin et al (2019), we analysed the determinants of food security using the experiential measure of food security developed by the FAO.…”
