Objectives Differences in exposure to secondhand smoke at the workplace, based on job category, have been assessed in some countries. While differences due to socioeconomic status have been assessed in Japan, few studies have been conducted to examine differences across job categories. We aimed to clarify the differences in nonsmokers' exposure to secondhand smoke at the workplace across job categories in Japan.Methods This cross-sectional study used data from an online survey conducted in 2017. A total of 1,739 participants, aged 20-69 years, were included. The dependent variable was exposure to secondhand smoke at the workplace, whereas the independent variable was job category, which was classified into the following 7 categories: 1) Management, Professional, and Technical; 2) Clerical; 3) Sales and Service; 4) Security; 5) Agriculture, Forestry, and Fishery; 6) Production Process, Transport, Cleaning, Packaging, etc.; and 7) Transportation, Machine Operation, Construction, and Mining. Analysis included estimates of the prevalence ratios (PRs) for the differences in exposure to secondhand smoke based on job category. In the analyses, sex, age, educational status, income, smoking environment at business, and awareness of secondhand smoke were considered covariates.Results The mean age of the participants was 43.3 years (SD=11.9); men constituted 60.5% of the study participants. A total of 529 individuals (30.4%) were exposed to secondhand smoke at the workplace in the past month. Of these, 171 (27.9%), 155 (27.1%), 116 (33.7%), 10 (45.5%), 7 (31.8%), 39 (34.5%), and 31 (58.5%) were found from the 1st to the 7th category, respectively. In the multivariate analysis, PRs (95% confidence interval) of exposure to secondhand smoke at the workplace among non-smokers were 1.27 (1.04-1.56), 1.61 (1.02-2.56), and 1.75 (1.33-2.31) for the Sales and Service category; Security category; and Transportation, Machine Operation, Construction, and Mining category, respectively, compared to the Clerical category.Conclusion Certain job categories may not be able to benefit from secondhand smoke prevention measures, although the measures have been promoted by the revised Health Promotion Act. It is, thus, necessary to monitor the situation of exposure to secondhand smoke at the workplace across diverse settings.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 August 2020.
All research outputs
#20,332,383
of 25,852,155 outputs
Outputs from [Nippon kōshū eisei zasshi] Japanese journal of public health
#217
of 457 outputs
Outputs of similar age
#291,169
of 398,451 outputs
Outputs of similar age from [Nippon kōshū eisei zasshi] Japanese journal of public health
#5
of 10 outputs
Altmetric has tracked 25,852,155 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 457 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.2. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 398,451 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
