  1. Notes: The proportion of LBW reporting substance use differed by age group (p ā‰¤ 0.002), and there was a trend for the use of all substances to decrease after 24 years of age (p < 0.001).
  2. Some participants did not supply data on both substance use and age and are not included in this table, hence the figures do not sum to the study population and the proportion of participants reporting substance use is different from that of the entire sample.
