Socioeconomic status (SES) was measured using estimated household income, years of participant education, and participant employment.
Recruitment was initiated with six 'seeds' (initial participants) who were purposively selected in consultation with key informants in the PWID community and diversified on characteristics including sex, age, education, and place where they buy drugs or inject.
The Compassionate Investigational New Drug program had very few initial participants.
General characteristics (e.g., age, BMI, parity, IIFAS scores, and parental education level) of participants who were included in the final analyses (n = 300) were similar to the characteristics of the initial participants (n = 600).
Of these, 3 ACM+HT and 2 CC participants were excluded because they were subsequently found to meet baseline exclusion criteria; 2 CC participants withdrew before the initial education session and 6 ACM+HT participants withdrew afterward.
After an initial education session, participants were informed of their intervention assignments.
All participants received initial standardized dietary education provided by trained staff.
initial vocational education and training.
In an initial interview participants gave contact details, education (age at leaving school, further and higher education, and highest qualification obtained), main occupation (and that of their spouse for women), and age at retirement.
Researchers then followed up participants for an average of 7.7 years after their initial participation.
