背景：胎盘生长对母体的影响有反应。斋月是一个一年一度的白天禁食期，在此期间，沙特阿拉伯的人们，包括孕妇，改变他们的饮食和体育活动。鲜为人知的是，这种改变的生活方式对胎盘development.Methods的影响：我们研究了7083名婴儿出生在一个为期四年的沙特国民在Unizah，一个小城市350公里以北的利雅得，沙特阿拉伯首都的出生记录。记录包括出生体重，胎盘重量和孕龄。结果：平均出生体重与欧洲值相似，但平均胎盘重量和胎盘重量与出生体重的比值较低。在斋月期间处于妊娠中期或晚期的婴儿中，平均胎盘重量和比率低于斋月期间不在子宫内的婴儿。在男孩中，平均胎盘比率为14.4%（妊娠中期）和14.5%（妊娠晚期），而在男孩中，平均胎盘比率为14.9%（p= 0.001）。
Background: Placental growth responds to maternal influences. Ramadan is an annual period of day-time fasting during which people in Saudi Arabia, including pregnant women, change their diets and physical activity. Little is known about the effects of this altered lifestyle on placental development.Methods: We studied the birth records of 7083 babies born over a four-year period to Saudi nationals in Unizah, a small city 350 km to the north of Riyadh, the capital city of Saudi Arabia. The records included birth weight, placental weight and gestational age.Results: Mean birth weight was similar to European values but the mean placental weight and ratio of placental weight to birth weight were lower. Among babies who were in the second or third trimester of gestation during Ramadan the mean placental weight and ratio were below those of babies who were not in utero during Ramadan. Among boys the mean placental ratios were 14.4 percent (second trimester) and 14.5 percent (third trimester) compared with 14.9 percent (p=
