Occupational injury disparities in the US hotel industry.

BACKGROUND: Hotel employees have higher rates of occupational injury and sustain more severe injuries than most other service workers. METHOD: OSHA log incidents from five unionized hotel companies for a three-year period were analyzed to estimate injury rates by job, company, and demographic characteristics. Room cleaning work, known to be physically hazardous, was of particular concern. RESULTS: A total of 2,865 injuries were reported during 55,327 worker-years of observation. The overall injury rate was 5.2 injuries per 100 worker-years. The rate was highest for housekeepers (7.9), Hispanic housekeepers (10.6), and about double in three companies versus two others. Acute trauma rates were highest in kitchen workers (4.0/100) and housekeepers (3.9/100); housekeepers also had the highest rate of musculoskeletal disorders (3.2/100). Age, being female or Hispanic, job title, and company were all independently associated with injury risk. CONCLUSION: Sex- and ethnicity-based disparities in injury rates were only partially due to the type of job held and the company in which the work was performed.

Use of a national reporting system for occupational injuries in Costa Rica.

Occupational injury surveillance in developing countries may be hindered by the lack of health data infrastructure as well the large numbers of informal-sector workers. The goal of this study was to elucidate the scope of occupational injury in the Monteverde district of Costa Rica using data collected through the national workers social security system. A list of occupational injuries occurring in the district reported to the National Insurance Institute (INS) central office between 1998 and 2002 was taken to the regional INS office, and the original injury reports for the cases were pulled. Specific data on the injuries were collected. There were 184 injuries reported during the five year period. Occupations with the highest number of injuries included production, building and grounds maintenance, and agricultural/forestry/fishing. Descriptive data showed that prevention efforts in this rural region should target food manufacturing, hotels, and construction.

A quantitative look at fluorosis, fluoride exposure, and intake in children using a health risk assessment approach.

The prevalence of dental fluorosis in the United States has increased during the last 30 years. In this study, we used a mathematical model commonly employed by the U.S. Environmental Protection Agency to estimate average daily intake of fluoride via all applicable exposure pathways contributing to fluorosis risk for infants and children living in hypothetical fluoridated and nonfluoridated communities. We also estimated hazard quotients for each exposure pathway and hazard indices for exposure conditions representative of central tendency exposure (CTE) and reasonable maximum exposure (RME) conditions. The exposure pathways considered were uptake of fluoride via fluoridated drinking water, beverages, cow's milk, foods, and fluoride supplements for both age groups. Additionally, consumption of infant formula for infants and inadvertent swallowing of toothpaste while brushing and incidental ingestion of soil for children were also considered. The cumulative daily fluoride intake in fluoridated areas was estimated as 0.20 and 0.11 mg/kg-day for RME and CTE scenarios, respectively, for infants. On the other hand, the RME and CTE estimates for children were 0.23 and 0.06 mg/kg-day, respectively. In areas where municipal water is not fluoridated, our RME and CTE estimates for cumulative daily average intake were, respectively, 0.11 and 0.08 mg/kg-day for infants and 0.21 and 0.06 mg/kg-day for children. Our theoretical estimates are in good agreement with measurement-based estimates reported in the literature. Although CTE estimates were within the optimum range for dental caries prevention, the RME estimates were above the upper tolerable intake limit. This suggests that some children may be at risk for fluorosis.
