Summary: | Objective
We evaluated the association of maternal pre‐pregnancy body mass index (BMI), gestational weight gain (GWG), and maternal smoking with aerobic fitness in young men aged 19–20 years.
Design
A 19–year prospective cohort study.
Setting
Data from the Northern Finland Birth Cohort 1986 (NFBC 1986) and the Sodankylä Jaeger Brigade, Finland, in 2005–6.
Population
Mothers and the 508 offspring in the NFBC 1986 who entered military service at the Sodankylä Jaeger Brigade in 2005.
Methods
Associations of weight, 12–minute running test (Cooper test), and muscle fitness index (MFI) of offspring on entry to military service were evaluated with antenatal factors, including maternal smoking, pre‐pregnancy BMI, and GWG.
Main outcome measures
Aerobic and muscle fitness of the offspring were evaluated by the Cooper test and MFI.
Results
Maternal smoking during pregnancy was associated with lower aerobic fitness of male adolescents, measured by the Cooper test (2356 m; 95% confidence interval, 95% CI 2265–2446 m), compared with the offspring of mothers who did not smoke during pregnancy (2537 m, 95% CI 2499–2574 m). This association was independent of the BMIs of both the mother and the offspring, GWG, and the smoking and physical activity of offspring (regression coefficient −140.6 m, 95% CI −273.1 to −8.0 m). High maternal pre‐pregnancy BMI and excessive GWG were also associated with lower aerobic fitness of the offspring; however, this association was mediated via the weight of the offspring.
Conclusions
Maternal smoking during pregnancy may have a negative impact on the aerobic fitness of the offspring.
Tweetable
Study shows that young men have lower aerobic fitness if their mothers smoked during pregnancy.
