"Here's a great article explaining how you've got to be careful when you read "studies" because you shouldn't interpret the findings as they appear first hand ....... you'll understand when you read the article.
Although this pilot project has provided valuable insight into these
childless women’s physical and mental health and wellbeing, it is not
without its limitations. This pilot study was based on a small
convenience sample of childless women in Victoria, Australia, thus these
findings must be considered with caution and cannot be generalised to
the wider population of childless women. Accordingly, the physical and
mental health and wellbeing of the women could not be compared by the
types of childlessness. However, it is possible that there are physical
and mental health and wellbeing differences between the types of
childlessness , which are masked in the current analysis.
What I liked about this study is that the writers acknowledged the
stigmatisation and marginalisation of women who are childless. The
researchers were not setting out to say to women “have babies or else
suffer the consequences you deserve” like so much of the
anti-abortion/pro-natalist medical literature. Instead, it looks as
though the writers are seeking to promote social acceptance of female
childlessness to treat causes of depression et al.
