Impact of smoking on the observed levels of apolipoprotein B: Data from NHANES 2007-2012.

Impact of smoking on the levels of apolipoprotein B (APOB) was evaluated by analyzing data from National Health and Nutrition Examination Survey for the years 2007-2012 for US adolescents aged 12-19 years and adults aged >=20 years. When adjustments were made for the effects of age, gender, race/ethnicity, body mass index, and poverty income ratio, smoking did not influence the observed levels of APOB for either adolescents or adults. Moreover, even the variables that represented intensity of smoking indicated, for example, by the number of days participants smoked during the last five days and/or the number of cigarettes smoked on the days they were smoked did not affect the levels of APOB. Also, type of smoking, cigarettes only, cigars only, or smokeless products only did not affect the levels of APOB. Every two years, adjusted levels of APOB decreased by 2.5% for adolescents and by 1.8% for adults.
