Guide PHIT Data: Smoking and Secondhand Smoke Exposure

This dataset includes model-generated estimates of the percentage of Massachusetts adults who report exposure to secondhand smoke at home, work or other places. Percentages are given for Massachusetts communities, counties, and the state overall. Values were estimated using information from multiple data sets including BRFSS data (2012 – 2014) and census data.

What you need to know

The Behavioral Risk Factor Surveillance Survey (BRFSS) is an annual survey that asks Massachusetts residents about their health and related behaviors, including smoking and secondhand smoke exposure.

Massachusetts residents were asked about their exposure to secondhand smoke (SHS) at their home, work, or other places. Among those who were employed, secondhand smoke exposure was defined as any exposure at work, at home, or in other places in the past 7 days. Among those who were not employed, secondhand smoke exposure was defined as any exposure at home or in other places in the past 7 days.

The percentage of residents exposed to secondhand smoke within counties and communities was estimated using BRFSS data collected in 2012, 2013, and 2014 as well as data from the US census. 

Explore these data

You can use these data to compare your community with other communities, the county, or the state.
 
Stakeholders, policymakers and the general public can use these data to help support policies that reduce the impact on secondhand smoke on health, such as smoke-free housing. 

Information about these data

Do not compare these values to those calculated using BRFSS data before 2011 due to a change in survey methods.

If confidence intervals of two groups overlap, the difference between the values may be due to chance and should be interpreted with caution. 

Because these values come from a mathematical model, the estimated values for communities may differ from the true percent of secondhand smoke exposure in that community.

Some communities are missing values because too few residents in those communities were surveyed on BRFSS.
