Pregnant women (n = 210) were excluded from all
analyses because meal patterns and dietary intake are likely to change
during pregnancy. Chi-square analyses were used to test for associations
between breakfast skipping (ate breakfast rarely/never, 1–2 d/wk, $3
d/wk) and categorical covariates. The scores for the dietary guideline
index, physical activity, self-efficacy for a healthy diet, attention paid to
health, family support and friend/colleague support for healthy eating,
and physical activity and sedentary behaviors were divided into thirds
for the analyses. Thirds were chosen because, although the sample size
was large, the number of breakfast skippers was low and would have
resulted in small cell sizes in multivariable models..
