Abstract
The effects were evaluated of nutritional and exercise intervention on the dietary habits and oxidative DNA damage in elderly women.We conducted eight health education sessions focusing on nutritional and exercise intervention with 36 women aged 64-86 years old (69.5±5.3 average age) in Seika-cho, Kyoto prefecture. The participants were divided into two groups, one combining exercise with nutritional intervention (NE), and the other with exercise alone (E). A food frequency questionnaire was conducted on anti-oxidative foods, and serum lipids, vitamins and urinary 8-OHdG were measured at the start and nine weeks later.The consumption of apple and nuts was significantly increased in the NE group, but not in the E group. The serum β-cryptoxanthin level was also significantly increased in the NE group, but not in the E group. The urinary 8-OHdG level was significantly decreased in the NE group, but not in the E group. It is suggested from these results that nutritional intervention with exercise was more effective than exercise alone for preventing oxidative DNA damage in elderly women.
