Objectives: Hurricane Katrina was an intense tropical cyclone that made landfall in the United States (US) in August 2005, causing catastrophic damage in several states. This study examined the impact of Hurricane Katrina on mental health status among US adults. Methods: Multilevel regressions based on the difference-in-differences study design were performed on individual-level data (N = 70,267) retrieved from the Behavioral Risk Factor Surveillance System 2004-2006 surveys. Results: Hurricane Katrina was found to be associated with an increase of 0.68 poor mental health days among residents of Katrina-affected states. The negative impact of Hurricane Katrina on mental health status tended to be larger among Louisiana residents, women, young and middle-aged adults, lower income respondents, and those with poor/fair self-rated physical health than among Mississippi residents, men, older adults, higher income respondents, and those with good/excellent self-rated physical health. Conclusion: Hurricane Katrina adversely impacted mental health of residents in Katrina-affected states, and the impact differed across population subgroups. Future studies should investigate other potential risk and protective factors for the mental health consequences of disasters. They should examine long-term impacts on mental health following disasters to better inform population-based mental health interventions for disaster survivors.

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.

Life satisfaction is a key component of people’s subjective well-being. This study assessed the relationship between relative income and life satisfaction among Chinese adults, using data from a cross-sectional survey. Individual-level data (N = 1369) came from the 2016 China Genuine Progress indicator Survey (CGPiS) conducted in Beijing and Chengdu, China. Ordered logistic regressions were performed to examine the relationship between relative income and life satisfaction among CGPiS adult respondents. Respondents’ life satisfaction was positively associated with relative income in comparison to their relatives and friends but not associated with relative income in comparison to their residing community and city. Subgroup analyses replicated the findings among male respondents and respondents with good or excellent self-rated health. In contrast, female respondents’ life satisfaction was positively associated with relative income in comparison to their city of residence, but not associated with relative income in comparison to their relatives, friends, and residing community. Life satisfaction among those with poor or fair self-rated health was not associated with any of the four dimensions of relative income. Relative income in comparison to relatives and friends was positively associated with life satisfaction in Chinese adults. Future studies adopting a longitudinal or experimental design are warranted to replicate the findings.
