They also excluded women during pregnancy and for six months after pregnancy, and recent immigrants.
The researchers analyzed hormonal contraceptive use and subsequent depression in two different ways. They evaluated women who had received a diagnosis of depression as well as women who had received a prescription for antidepressants; these analyses were run separately, and they obtained statistically equivalent results.
All forms of hormonal contraception were associated with an increased risk of developing depression, with higher risks associated with the progesterone-only forms, including the IUD.
This risk was higher in teens ages 15 to 19, and especially for non-oral forms of birth control such as the ring, patch and IUD. Liao, Liao, P. Half a century of the oral contraceptive pill.

The Hub is a platform to share ideas, cases and concepts that bridge the gap between academia and the real world. Think about it as the real world textbook, a platform rich with experiences.
Many brilliant solutions, the so called tacit knowledge, is embedded in the brains of people that do not have the platform to express them or at least reach a wider audience. The Hub is a device to unlock this knowledge and share it with the wider world. The Hub gives you an opportunity to make a difference. Common concern: Hormones in the pill, IUDs, vaginal rings, etc.
The lack of data on this topic is quite challenging, which is why we were so motivated to conduct this study. Clinical studies and randomized placebo-controlled trials of women with psychiatric disorders have reported similar rates of mood symptoms in hormonal contraceptive users compared with nonusers, Wisner said. In some cases, hormonal contraceptives may even help stabilize or reduce the rates of mood symptoms in women with psychiatric disorders, the study found.
The mental and physical stress of an unintended pregnancy could trigger a new and recurrent bout of depression, including postpartum depression, Wisner added. The highest prevalence of mental illness But scientists, like Dr Channa Jayasena from Imperial College London, were quick to point out that the "study does not prove [and does not claim] that the pill plays any role in the development of depression". Users too made this point, like the freelance writer Laura Sneddon: "As someone who finds their depression worsened by hormonal contraception Others, like Dr Diana Mansour of Newcastle University, pointed out there are many other possible causal factors - including emotional and relationship problems: 'With having a million women, there are things that are variable here.
But Prof Lidegaard believes there is a causal influence - even though the research proves only a correlation. Several experts said women should not be alarmed and should continue taking the pill as normal - though this was dismissed as "pillsplaining" by the author Holly Grigg-Spall.
