How does secondhand smoke affect kids?

A new study published in JAMA Ophthalmology found an association between secondhand smoke and choroidal thinning.

Tell me what we know and don't know.

We know that secondhand smoke can have adverse ocular effects in adults, but we don't know how it affects children.

Tell me about the study.

There were 1,400 kids between the ages of 6 and 8 included in the study. More than 60% of these kids had no secondhand smoke exposure, while almost 33% did. Using swept-source OCT, the research team found that the kids with secondhand smoke exposure had choroids 6 μm to 8 μm thinner than those without exposure.

Is this a big deal?

The authors note that although this seems to be a small amount of choroidal thinning, we know that choroidal thinning leads to ophthalmic diseases, including macular holes and AMD. These findings add to the potentially harmful effects of secondhand smoke on children’s ocular health and development. (via)
