This article examines subgroup differences in the health status of Hispanic adults in comparison to non-Hispanic whites and non-Hispanic lacks. We pay particular attention to the influences of nativity and duration of residence in the United States. Data are pooled from the National Health Interview Survey (NHIS) for 1989–94. Puerto Ricans exhibited the worst health outcomes of any group (including whites and blacks) for each of the three health measures. Persons of Central/South American origin

The Sewol ferry disaster severely shocked Korean society. The objective of this study was to explore how the public mood in Korea changed following the Sewol disaster using Twitter data. Data were collected from daily Twitter posts from 1 January 2011 to 31 December 2013 and from 1 March 2014 to 30 June 2014 using natural language-processing and text-mining technologies. We investigated the emotional utterances in reaction to the disaster by analyzing the appearance of keywords, the human-made d

Although several studies have reported that social isolation is one of the important health risk factors in the elderly population living in urban areas, its effects on vulnerability to heatwaves have been studied relatively less than climatic and other socio-economic factors. Thus, we investigated the association between social isolation levels and heatwave-related mortality risk in the elderly population in 119 urban administrative districts in Korea, using a time-series multi-city dataset (20

This study examines disparities in disability status across 15 Asian and Pacific Islander American (API) subpopulations and how nativity and duration in the U.S. influence these differences. Employing three disability questions (work limitations, mobility limitations, and self-care limitations) from the 1990 PUMS, the authors find substantial heterogeneity in disability status across API subgroups: while Japanese American adults have the most favorable outcomes, Other Southeast Asian adults (Lao

BACKGROUND: As suggested as early as in 2006, logs of queries submitted to search engines seeking information could be a source for detection of emerging influenza epidemics if changes in the volume of search queries are monitored (infodemiology). However, selecting queries that are most likely to be associated with influenza epidemics is a particular challenge when it comes to generating better predictions. OBJECTIVE: In this study, we describe a methodological extension for detecting influenza

BACKGROUND: This study examined the mediating function of body weight perception (BWP) in the relation between body mass index (BMI) and unhealthy weight control behaviors (UWCBs; eg, fasting, using diet pills, or laxatives), and between BMI and suicidal ideation. It also explored the correlation between exposure to multiple UWCBs and suicidal ideation among Korean adolescents. METHODS: Data on BMI, BWP, UWCBs, and suicidal ideation were obtained from the 2006 Korean Youth Risk Behavior Web-base

OBJECTIVES: Although waged workers' working conditions have notably diversified in South Korea, there is little research addressing this issue. This study explores the relationship between working conditions and engagement in leisure-time physical activities (LTPA) among waged workers in South Korea. METHODS: Data from 19- to 64-year-old waged workers (men=2,562, women=1,627) from the 11th wave of the Korean Income and Labor Panel Study were included in this study. Multiple logistic regression a

BACKGROUNDS: This study examines social inequalities in life expectancy and mortality during the transition period of the Korean economic crisis (1993-2010) among Korean adults aged 40 and over. METHODS: Data from the census and the national death file from the Statistics Korea are employed to calculate life expectancy and age-specific-death-rates (ASDR) by age, gender, and educational attainment for five years: 1993, 1995, 2000, 2005, and 2010. Absolute and relative differences in life expectan

This study aims to provide a systematical introduction of age-period-cohort (APC) analysis to South Korean readers who are unfamiliar with this method (we provide an extended version of this study in Korean). As health data in South Korea has substantially accumulated, population-level studies that explore long-term trends of health status and health inequalities and identify macrosocial determinants of the trends are needed. Analyzing long-term trends requires to discern independent effects of

BACKGROUND: Recent life expectancy gains in high-income Asia-pacific countries have been largely the result of postponement of death from non-communicable diseases in old age, causing rapid demographic ageing. This study compared and quantified age- and cause-specific contributions to changes in old-age life expectancy in two high-income Asia-pacific countries with ageing populations, South Korea and Japan. METHODS: This study used Pollard's actuarial method of decomposing life expectancy to com

OBJECTIVE: Social media data are a highly contextual health information source. The objective of this study was to identify Korean keywords for detecting influenza epidemics from social media data. METHODS: We included data from Twitter and online blog posts to obtain a sufficient number of candidate indicators and to represent a larger proportion of the Korean population. We performed the following steps: initial keyword selection; generation of a keyword time series using a preprocessing appro

Community-level interventions providing immigrants opportunities to increase social networking members from the same country as well as the native-born in a host country may be helpful resources for improving mental health among immigrants in South Korea. Also, raising awareness of racial discrimination among members in South Korea would be crucial.

Although a growing body of literature has indicated that unemployment has a positive association with suicide, the dynamic aspects of unstable employment have not yet been considered in suicidology. This study explored the association between employment stability and completed suicide among people aged 25-34 years in 20 OECD (Organization for Economic Cooperation and Development) countries with time-series data (1994-2010). In order to consider the different aspects of unstable employment, we te
