Parental physical activity is associated with objectively measured physical activity in young children in a sex-specific manner: the GECKO Drenthe cohort

Table 4 The association between paternal LPA and sedentary time in sons is explained by paternal education level

Std. B, standardized β coefficient; 95% CI (β), 95% confidence interval of the β coefficient. Model 1 presents the mutually adjusted model for explaining sedentary time in sons using both LPA and the father’s education level. Model 2 presents further adjustment of model 1 by family income. Paternal LPA was ln-transformed to obtain a normal distribution of the residuals. The outcome ‘sedentary time in sons’ is used in hours/day and was normally distributed. For interpretation, a β of 0.245 for paternal education level means fifteen more minutes per day (0.245 h) of sedentary behaviour for the sons of high and low educated fathers
