Collection for the PALS (Pregnancy and Lifestyle Study), a community-based study of lifestyle on fertility and reproductive outcome

In order to assess the possible effects of lifestyle on fertility and pregnancy outcome, the PALS (Pregnancy and Lifestyle study) collected extensive data on a broad range of parameters termed 'lifestyle' from couples who were planning a natural (non-assisted) pregnancy in the coming months. There was no intervention. Participants were recruited over a six year period from 1988 to 1993 in response to extensive promotion in the local media. Male and female partners were interviewed independently and all interviews were conducted prospectively before the couple attempted to conceive. The result of each month of 'trying' was recorded and pregnancies were confirmed by urine tests and by ultrasound. The length of gestation of each pregnancy was recorded and pregnancies at term were classified with respect to weight. Multiple pregnancies and/or babies with congenital abnormalities have been excluded from the dataset. This collection contains two datasets. An open access de-identifiable dataset and a restricted identifiable set.

为评估生活方式对生育能力与妊娠结局的潜在影响，PALS（Pregnancy and Lifestyle study，妊娠与生活方式研究）针对未来数月计划自然受孕（非辅助生殖）的夫妇，收集了涵盖大量被归类为“生活方式”相关参数的详尽数据。本研究无任何干预措施。研究对象于1988年至1993年的6年间招募，招募工作依托当地媒体的广泛宣传开展。男女双方分别接受独立访谈，且所有访谈均在夫妇尝试受孕前前瞻性完成。研究记录了每一个月的“尝试受孕”结果，妊娠通过尿液检测与超声检查予以确认。本研究记录了每一次妊娠的孕周，足月妊娠则按新生儿体重进行分类。本数据集已剔除多胎妊娠及/或伴先天异常的胎儿数据。本合集包含两类数据集：一类为可公开获取的去标识化数据集，另一类为受限制的可识别数据集。
