Asian dust storms result in a higher risk of the silicosis hospital admissions.

Purpose: Previous studies found that silicosis was majorly associated with occupation-related risks. However, little evidence was available to clarify the relation between Asian dust storm (ADS) and silicosis hospital admissions. This present paper aims to investigate the association between ADS events and hospital admissions for silicosis. Methods: We applied a Poisson time-series regression on the 2000-2012 National Health Insurance Research Database in Taiwan, linking air quality data and ambient temperature data to estimate the impact of ADS on silicosis hospital admissions in the age-specific groups. Results: A total of 2154 hospital admissions were recorded for silicosis in Taiwan, for a daily average number of 0.45. The number rises from 0.43 on a day without ADS to 0.70 on the outbreak day and continues increasing to 0.83 one day after outbreak. Among patients under 45, the effect of ADS appears on the event day as well as several post-event days (lag2-6) at the significant level of p < 0.1. There is also a significant lag effect on post-event day 2 (p < 0.05) for those aged above 74. Conclusion: Asian dust storms do result in a rise of silicosis hospital admissions, particularly for those above 74, those under 45, and for females.

Do Internet Users Lead a Healthier Lifestyle?

Internet use has spread rapidly worldwide in recent years, but the proportion of older people who use it remains low in Taiwan. Meanwhile, due to population aging in the country, chronic diseases have become more prevalent among older people. This study explores the link between exposure to the Internet and adoption of a healthy lifestyle among the middle-aged and elderly people. Data are drawn from the Topic on Health of the 2011 Taiwan Social Change Survey. We use the logistic regression as the baseline model and apply the propensity-score weighting method to identify the effect of Internet use on exercising, vegetable and fruit eating, betel nut chewing, smoking, and heavy drinking. Our results show that people aged 40 years and older who use the Internet regularly are more likely to adopt an overall healthy lifestyle. The findings suggest that the Internet is a good channel to enhance people's health investment.

Social capital and preventive care use among the elderly under Taiwan's National Health Insurance.

OBJECTIVE: The National Health Insurance (NHI) system in Taiwan provides free annual preventive care services and other disease-specific preventive care services under low copayments to people aged 65 and older, yet their utilization rates remain low ever since implementation. This study investigates whether social capital is associated with preventive care use among people aged 65 and older. METHOD: Using the 2009 National Health Interview Study, this study measures social capital by the elderly's social network and social participation, and employs the logistic regressions to estimate the association between social capital and the odds of using a variety of preventive care services. RESULTS: The results show that social capital in terms of social network and social participation is significantly associated with the use of NHI general preventive care services. For disease-specific preventive care, it is social participation, rather than social network, that is related to the utilization rate. CONCLUSION: The associations between social capital and different types of preventive care use found in our study could be considered as an important factor when making policies to promote the utilization of preventive care.

Sanction changes and drunk-driving injuries/deaths in Taiwan.

Driving under the influence (DUI) is one of the major causes of traffic accidents in Taiwan. About 5% of injuries involve DUI, and nearly 20% of deaths are due to alcohol-related crashes. During early 2006 to the end of 2014, the authorities in Taiwan increased the severity of fine and jail penalties for DUI offenders three times. At the same time, the monthly drunk-driving injures decreased nearly 40% and the monthly alcohol-related traffic death dropped more than 80%. In this paper, we examine the effects of sanction changes on the reduction of drunk-driving casualties during this period. We find that drunk-driving injuries and deaths significantly dropped after the statutory changes. The reduction was immediate following all sanction changes that raised the maximum fines or jail terms of DUI offenders. Policies that increased the maximum jail terms of DUI offenders seem to have a better gradual effect on the reduction of alcohol-related traffic casualties. Although increased sanctions are found to be effective in reducing drunk-driving casualties, we need more future research to examine the policy-to-perception and the policy-to-behavior links.

Influence of Asian dust storms on daily acute myocardial infarction hospital admissions.

OBJECTIVE: This study was the first to explore the relationship between Asian dust storm events (ADS) and acute myocardial infarction (AMI) hospital admissions by applying time series models. DESIGN AND SAMPLE: Nationwide population-based hospitalization claims data in Taiwan were used. There were 143,063 AMI admissions during 2000-2009. MEASURES: An autoregressive with exogenous variables (ARX) time series model was used to investigate the dynamic connection between AMI hospital admissions and ADS events. RESULTS: AMI hospitalizations significantly spiked on post-ADS day three. Among the total population, 3.2 more cases of AMI admissions occurred on post-ADS day three. When the data were stratified by age and gender, the same delayed effect was present in the male population, especially those aged 45-64 and over 74. CONCLUSIONS: Our study shows that although an ADS event does not cause an immediate incidence of AMI, storms may increase AMI incidence through a delayed effect. Hence, AMI prevention is not only important during a dust storm, but particularly so in subsequent days. During the days after an ADS, exposure to dust should be minimized by staying indoors as much as possible and by wearing a mask when exposure to dust is unavoidable. This is especially true for working and older adults. Nurses at local public health centers can increase awareness and promote public safety by providing health information to local communities regarding the link between dust storms and AMI.

The effectiveness of preventive care at reducing curative care risk for the Taiwanese elderly under National Health Insurance.

Whether provision of free preventive care for the elderly under National Health Insurance has reduced the risk for curative care use raises much concern in Taiwan. This study analyzes the relationship by examining the impact of health examination utilization on the utilizations of outpatient care and inpatient care. Data come from the 2005 National Health Interview Survey and National Health Insurance Research Database. A two-stage method is used in the estimation. We found a negative relationship between the utilization of preventive care and hospitalization care in terms of length of stay and medical expenditures. On average, the elderly people who used preventive care tended to have 16 shorter hospitalization stays and NTD64,220 lower hospitalization expenditures than their counterparts. In order to improve the health of the elderly and reduce the escalation of medical expenditures due to aging, including preventive care in the health insurance is a very effective strategy.
