Abstract 35: Unprocessed and Processed Meat Consumption and Blood Pressure: The INTERMAP Study

Background: Evidence from prospective cohort studies indicates that consumption of processed meats is associated with higher incidence of CHD. Processed meats are high in saturated fatty acids, cholesterol, and preservatives including sodium that may unfavorably influence blood pressure (BP), but evidence is limited. We therefore investigated associations with BP of unprocessed and processed meat consumption, including types of processed meats. Methods: We used cross-sectional data from the INTERMAP Study on 4,680 men and women aged 40-59 years from Japan, China, UK, and US. During four visits, eight BPs and four 24-hr dietary recalls were collected. Processed meats included preserved meats; fresh processed meats (ready-made, salted, and/or spiced, no curing), bacon, ham (cured and cooked), cold cuts and sausages, and canned meat products. Country-specific linear regression coefficients were estimated and pooled, weighted by inverse of their variance. Adjustments were made for demographic (age, gender, sa...
