PHYSICAL-ACTIVITY, LIPIDS, APOLIPOPROTEINS, AND LP(A) IN THE NORTHERN-IRELAND HEALTH AND ACTIVITY SURVEY

In a cross-sectional study using a two-stage probability sample (N = 1 ,600) of the population of Northern Ireland, there was an inverse asso ciation between the highest recorded recent activity and total cholest erol (P less than or equal to 0.01), LDL (P less than or equal to 0.01 ), triglyceride (P less than or equal to 0.05) and Chol:HDL ratio (P l ess than or equal to 0.001) in males, and total cholesterol (P less th an or equal to 0.001), LDL (P less than or equal to 0.001), and trigly ceride (P less than or equal to 0.01) in females; between habitual act ivity and HDL (P less than or equal to 0.05) in males and total choles terol (P less than or equal to 0.05) and triglyceride (P less than or equal to 0.01) in females. There was a relationship between the highes t recorded activity and apoAI (P less than or equal to 0.01) and apoB (P less than or equal to 0.01) in males and with apoB (P less than or equal to 0.001) in females; between habitual activity and apoAI (P les s than or equal to 0.01) and apoAII (P less than or equal to 0.05) in males and apoB (P less than or equal to 0.01) in females; between past activity and Lp(a) in females (P less than or equal to 0.05). After a djustment for possible confounding factors, total cholesterol (P less than or equal to 0.05) and LDL (P less than or equal to 0.05) were une xpectedly higher in males who were active throughout life. Total chole sterol (P less than or equal to 0.05) and LDL (P less than or equal to 0.001) were higher in females with highest recorded activity and trig lycerides lower (P less than or equal to 0.05) in those habitually act ive. An association between highest recorded activity and apoAI (P les s than or equal to 0.01), and past activity and apoAI:apoB ratio (P le ss than or equal to 0.05) was shown in males and in females, after adj ustment, and between apoB (P less than or equal to 0.05) and highest r ecorded activity.
