Table 1 shows the socio-demographic correlates of lifetime
and 12-month BPD. The odds of having lifetime bipolar disorder
were significantly lower among those aged 50–64 years than that
among those aged 18–34 years (reference group). The odds were
higher among those who were divorced/separated (as compared
to single); those who had secondary or vocational education (as
compared to those with a university education). The odds of
having BPD in the last year were significantly higher among
Indians (as compared to Chinese), and those divorced/separated
(as compared to single). The odds of having 12-month BPD were
also lower among those aged between 50 and 64 years as
compared to those aged 18–34 years.
