Childhood exposure to passive smoking and bone health in adulthood. The Cardiovascular Risk in Young Finns Study
In this longitudinal study, researchers investigated the independent effects of exposure to passive smoking in childhood on adult bone health. Participants included 1,422 people who were followed up for 28 years from baseline in 1980 (age 3-18 years). Peripheral bone characteristics were evaluated in adulthood using quantitative computed tomography (pQCT) in the tibia and radius, and calcaneal mineral density was estimated by quantitative ultrasound. Children whose parents smoked and had high levels of cotinine had a significantly lower bone sum index derived from pQCT vs smoking parents with low levels of cotinine. According to findings, children of smoking parents having a greater risk of experiencing bone health impairment in adulthood.
