美国的医疗保险
A deductible is the amount you pay for health care services each year before your health insurance begins to pay. The higher a plan’s deductible, the lower the premium. The lower a plan’s deductible, the higher the premium. You’ll pay more each month, but your plan will start sharing the costs sooner because you’ll reach your deductible faster.
A copay is the fixed amount you pay for a covered health care service like an office visit or pick up prescription drugs after you've paid your deductible.
A coinsurance is a set percentage the customer pays for a covered service. For instance, a copay for a doctor’s visit may be $25, you would pay a $25 copay for each visit to your doctor. On the other hand a coinsurance for a similar visit could be 30% and if a doctor’s appointment costs your insurance company $100, then you would owe $30 at the time of your visit.
An out-of-pocket maximum is the amount that you reach that amount you will not have to pay anymore out-of-pocket for covered care for the rest of the year – this includes coinsurance and copay.

如何选择叶酸
Folic acid is the man-made form of folate, a B vitamin.
Many breakfast cereals (in U.S.) have 100% of your recommended daily value (400 micrograms) of folic acid. Folate is found naturally in some foods. Foods that are naturally high in folate include:
* unpopulated spinach and other dark green, leafy vegetables
* unpopulated oranges and orange juice
* unpopulated nuts
* unpopulated beans
* unpopulated poultry (chicken,turkey,duck, and geese) and meat
* unpopulated whole grains

Most multivitamins sold in the U.S. contain 400 micro-grams, or 100% of the daily value, of folic acid. Look for "USP" or "NSF" on the label when choosing vitamins. These "seals of approval" mean the pills are made properly and have the amounts of vitamins it says on the label. Check the "Supplements Facts" label to be sure you are getting 400-800 micrograms of folic acid. Some brands list the word “folate” on the label, others use “folic acid,” but either term is okay as long as the supplement provides 400 mcg.
1 mcg DFE = 0.6 mcg folic acid and 1 mcg L-5-methylfolate = 1 mcg folic acid

怀孕期间安全性行为?
不过,有两点需要提醒你:第一,在怀孕期间子宫颈会更敏感些,如果你的伴侣在做爱时冲击了它,你会流点血,这很正常,不需要担心。第二,当你进入怀孕后期,好用的古老的传教士体位不会像以前那么奏效了。发挥一点创造力吧!
孕妇可以洗热水澡吗?
研究人员调查了17种先天畸形。他们发现其中两种(一种称为腹裂的肠道问题和一种称为无脑儿的神经管缺陷问题)与母亲洗热水澡有关。当然我们难以据此就得出可靠的结论。或许这些发现是偶然的,因为研究者测试了相当多的结果。然而,还有其他研究发现了热水澡对神经管缺陷有同样的影响。这种影响在动物试验中得到了验证,动物试验可以在更加可控的环境中开展(研究人员随机升高某些怀孕动物的体温而不对其他动物升温)。
总之,在妊娠早期体温升高会增加婴儿先天畸形的风险看起来是很有可能的,例如,婴儿脊柱裂和无脑儿的风险会很大。这意味着任何使你体温升高的事都是危险的:发烧、使用热水浴缸、洗非常热的热水澡,当然也包括高温瑜珈。需要重点注意的是:真正有关系的是让你的体温升高到101华氏度(38.3摄氏度)左右。热水浴缸通常约为105华氏度(40.6摄氏度),跟高温瑜珈一样。长时间在105华氏度(40.6摄氏度)的环境中做运动会升高你的体温,但是冷却的热水浴缸或者高温瑜珈的清凉版本[某些只有85~90华氏度(29.4~32.2摄氏度)]是没问题的。另外,神经管缺陷的问题仅限于妊娠早期;该时期结束胎儿神经管的形成就完成了。
你可能会问自己一个问题:那炎热天气会怎样?这是一回事吗?研究人员发现炎热天气似乎促使孕妇提前进入分娩期(约提前5天)。虽然没有在这项研究中提及,但在怀孕后期洗热水澡或做高温瑜珈可能也有这种效果。结论是如果外面的天气是105华氏度(40.6摄氏度),而你怀孕36周了,那么你应该待在屋子里。
