Alternatives: "in earlier stages" or "during prior phases".
*Adjustment for risk factors assessed at phases 3, 5, and 7. †Risk factors updated at phases 3, 5, and 7 and additionally adjusted for risk factor at previous phase; cumulative exposure to high triglycerides not assessed for time period between phases 1 and 3, owing to lack of data at phase 1. ‡Percentage attenuation in log HR=100× βSES−βSES+risk factor(s))/ βSES), where β=log(HR).
Obesity at one previous measurement phase was associated with a 2.43-hour/week (95% CI=0.07, 4.78) increase in TV viewing; obesity at three previous phases was associated with a 7.42-hour/week (95%CI=2.77, 12.46) increase in TV-viewing hours/week at Phase 5. Sitting time was not associated with obesity cross-sectionally or prospectively.
We assessed this by adjusting, at each follow-up period, for the risk factors/markers at the current phase plus at the previous phase (two phases capturing an exposure period of approximately five years).
In addition, there was no evidence of associations with grip strength in the follow-up phases adjusting for its measure at a previous phase.
After it allowed Barnet to compulsory-purchase homes at West Hendon last year and Southwark to go ahead with compulsory purchase at the Heygate and on previous phases of the Aylesbury, it has blocked the latest compulsory purchase order at the Aylesbury.

Perhaps, in previous phases of my life, I have concentrated on the "gathering".
We can calculate an amount of ( {I_{0,3}}^-{I}_{0,3}^ ) by measuring I 0,3 + and recalling ( {I}_{0,3}^ ) which was stored at C1 from the previous phase I.
Here, the subtraction is performed by the current of M2 which can recall ( {I}_{0,3}^ ), stored at C1 during the previous phase I, as shown in Fig. 2b.
Phases 2, 3 and 4 each used individual, self-administered questionnaires that were mailed between 1987 and 1989, 1993 and 1995, and 1995 and 1998, respectively, to all cohort members who were presumed alive at the end of the previous phase.
