A life-style physical activity intervention and the antibody response to pneumococcal vaccination in women.

Abstract

OBJECTIVE To assess whether a life-style physical activity intervention improved antibody response to a pneumococcal vaccination in sedentary middle-aged women. METHODS Eighty-nine sedentary women completed a 16-week exercise (physical activity consultation, pedometer, telephone/e-mail prompts; n = 44) or control (advisory leaflet; n = 45) intervention. Pneumococcal vaccination was administered at 12 weeks, and antibody titers (11 of the 23 contained in the pneumococcal vaccine) were determined before vaccination and 4 weeks and 6 months later. Physical activity, aerobic fitness, body composition, and psychological factors were measured before and after the intervention. RESULTS The intervention group displayed a greater increase in walking behavior (from mean [standard deviation] = 82.16 [90.90] to 251.87 [202.13]) compared with the control condition (111.67 [94.64] to 165.16 [117.22]; time by group interaction: F(1,68) = 11.25, p = .001, η(2) = 0.14). Quality of life also improved in the intervention group (from 19.37 [3.22] to 16.70 [4.29]) compared with the control condition (19.97 [4.22] to 19.48 [5.37]; time by group interaction: F(1,66) = 4.44, p = .039, η(2) = 0.06). However, no significant effects of the intervention on antibody response were found (time by group η(2) for each of the 11 pneumococcal strains ranged from 0.001 to 0.018; p values all >.264). CONCLUSIONS Participation in a life-style physical activity intervention increased subjective and objective physical activity levels and quality of life but did not affect antibody response to pneumococcal vaccination.
