PEER REVIEWER COMMENTS:
GENERAL COMMENTS: This revised manuscript unfortunately remains unclear in multiple
places and the English remains of low quality, creating further confusion on the variables and
intent of the manuscript
REQUESTED REVISIONS:
The authors state the purpose of the manuscript is to: 2. It remains challenging to understand
what constitutes a Migrant woman -  this sentence on Lines 62-28 is unclear "special attention
should be given to the health status of enormous-scale migrant women of childbearing age, who
are simultaneously on migration and at the age of childbearing. " and is an example of the poor
English throughout the manuscript. What is a migrant? How is it defined? What does it mean to
be on migration? These added statements about the purpose "1. Explores how fertility behavior
affects the health status of migrant women of childbearing age in China from a new research
object (what is a new research object?), which is a further exploration and innovation of related
studies. (which studies? how is this innovative? shouldn't this type of editorialization be in the
discussion?  2. How the occurrence of childbearing during migration affected maternal health
when migrant women of childbearing age bear the dual burden of migration and childbirth (there
is so much going on and redundant in this sentence it is unclear - do you mean actual birth of
children or being in that age group?). 3. Explain the current fertility difficulties in China from the
new perspective of the impact of childbearing on women's health. (it is unclear how this question
can be answered based on the data collected - this seems to be related to a general population
and not the specific migrant population noted by the authors. The authors are proposing a basic
science principal of somatic cell maintenance towards health and health behaviors with a very
unclear connection. The authors propose this hypothesis, and it is unclear if this is meant to be the
purpose of the study "Therefore,  we propose hypothesis 2:An improvement in socioeconomic
status can significantly mitigate the negative impact of fertility behaviors on the health of
migrant women of childbearing age." - how can the authors test this hypothesis with the data they
have?  The discussion re-states a different research question "this paper examines the influence
of fertility behaviors on the self-rated health of migrant women of childbearing age, an extended
study of this issue" - not clear what the extended study refers to?
