Fergusson of Australia has published more data on his birth cohort from ChristChurch, New Zealand. This time, he’s claiming causal relationship between abortion and later mental illness. A 3 invited comments in the same journal seem to accept that his conclusion is true: Abortion responsible for depression, anxiety, and substance abuse, at least do some degree.
The articles are in the British Journal of Psychiatry.for pay, but here’s the discussion:
(a) For both models there was consistent evidence that even after extensive covariate adjustment, exposure to abortion was associated with a modest but detectable increase in rates of mental disorder. The concurrent data suggested that after adjustment for confounding those exposed to abortion had
rates of mental health problems that were 1.37 (95% CI 1.16–1.62) times higher than for those who had not become pregnant (P50.001). The lagged model produced a slightly lower estimate of 1.32 (95% CI 1.05–1.67, P50.05).
(b) Pregnancy loss was associated with a modest increase in the rate of problems using the concurrent measures of pregnancy outcome, with those who experienced a pregnancy loss having a rate of mental health problems that was 1.25 (95% CI 1.01–1.53) times the rate for those who were never pregnant (P50.05). However, under the lagged model, pregnancy loss was not associated with later outcomes, with an adjusted RR of 1.06 (95% CI 0.79–1.43, P40.70).
(c) For both models, having a live birth, whether with or without
an unwanted/adverse reaction, was not associated with significant
increases in the overall rate of mental health problems when due allowance was made for confounding variables
