High levels of rheumatoid factor (in general, above 20 IU/mL, 1:40, or over the 95th percentile; there is some variation among labs) occur in rheumatoid arthritis (present in 80%) and Sjögren's syndrome (present in 50-70% of primary forms of disease). [11] The higher the level of RF the greater the probability of destructive articular disease.
Rh(D) status of an individual is normally described with a positive (+) or negative (−) suffix after the ABO type (e.g., someone who is A+ has the A antigen and Rh(D) antigen, whereas someone who is A− has the A antigen but lacks the Rh(D) antigen). The terms Rh factor, Rh positive, and Rh negative refer to the Rh(D
A woman who is 36–24–36 (91.5–61–91.5) at 5 ft 3 in (1.60 m) tall looks different from a woman who is 36–24–36 at 5 ft 8 in (1.73 m) tall. Since the latter woman's figure has greater distance between measuring points, she will likely appear thinner than her former counterpart, again, even though they share the same measurements.
Globally, it is estimated that 21.2% of women and 6.3% of men over the age of 50 have osteoporosis, corresponding to a total of around 500 million people worldwide. [194] About 15% of Caucasians in their 50s and 70% of those over 80 are affected. [ 7 ]
It is the most common reason for death of males and females over 20 years of age in the United States. [139] After analysing data from 2 111 882 patients, the recent meta-analysis revealed that the incidence of coronary artery diseases in breast cancer survivors was 4.29 (95% CI 3.09–5.94) per 1000 person-years.

Breastfeeding can generally be attempted after breast augmentation or reduction surgery, [252] however prior breast surgery is a risk factor for low milk supply. [ 253 ] A 2014 review found that women who have breast implant surgery were less likely to exclusively breast feed, however it was based on only three small studies and the reasons for ...
A U.S. federal survey of food consumption determined that for women and men over the age of 19, average iron consumption from foods and beverages was 13.1 and 18.0 mg/day, respectively. For women, 16% in the age range 14–50 years consumed less than the Estimated Average Requirement (EAR), and for men ages 19 and up, fewer than 3%. [ 14 ]
Injection drug use (IDU) is a major risk factor for hepatitis C in many parts of the world. [59] Of 77 countries reviewed, 25 (including the United States) were found to have a prevalence of hepatitis C of 60–80% among people who use injection drugs. [60] [59] Twelve countries had rates greater than 80%. [60]
