Entry in to the WHI. Participants have been categorized into “never smokers,” “former smokers,” and “current smokers” based on their smoking history. Levels of alcohol intake (g/d) and total energy intake (kcal/d) were also calculated in the FFQ. Physique weight and height had been measured at baseline entry in to the WHI, and BMI was calculated as physique weight (kg) divided by height (m) squared. The degree of physical activity in metabolic equivalent hours per week was estimated on the basis of selfreported duration of diverse varieties of physical exercise, weighted by their intensity levels. Measurement of peripheral leukocyte TLs. The measurement of TL has been described elsewhere (14). In short, we applied the method proposed by O allaghan et al. (21) in a highthroughput, 384well format making use of Applied Biosystems 7900HT PCR Method (Applied Biosystems by Life Technologies Corporation). Mean TL per chromosome was calculated with the use on the following formula: (TL/copies of diploid 908 Song et al.ResultsA total of 4029 WHI participants had been incorporated within this study. We retained three elements within the exploratory element analysis that with each other accounted for 85.6 in the total variance inside the original 23 variables (Supplemental Table 1). The initial element accounted mostly for SMSFAs [including butyric (four:0), hexanoic (6:0), octanoic (eight:0), decanoic (ten:0), and lauric acid (12:0)]. The second element primarily represented plant source FAs [including mainly arachidic (20:0) and gadoleic acid (20:1), also with fairly massive element loadings of behenic (22:0), oleic (18:1), linoleic (18:two), and linolenic acid (18:three)]. The third aspect nearly exclusively accounted for marinesource FAs, like EPA (20:5n23), docosapentaenoic acid (DPA, 22:5n23), and DHA (22:6n23). Participantscharacteristics in accordance with quartiles of TL are summarized in Table 1.
