| Outline of Final Research Achievements |
The metabolic equivalents (METs) for the physical activity (PA) intensity of the Japan Nurses’ Health Study (JNHS) questionnaire were estimated based on the data of accelerometers with the Markov Chain Monte Carlo (MCMC) simulation: 1.2 METs for “Sitting work”, 1.6 METs for “Standing work”, 1.8 METs for “Walking work”, and 4.5 METs for “Heavy work”, 1.1 METs for sedentary time, 2.4 METs for “Moderate physical activity”, 4.4 METs for “Hard physical activity”, and 9.4 METs for “Very hard physical activity”. We validated that the JNHS PA questionnaire and estimated MET values were useful for epidemiological surveys.
In regard to cognitive function, it was difficult to develop of a self-administrated simple assessment method for cognitive function. Therefore I adopted a “reporting an incorrect age” as an appropriate index of cognitive dysfunction.
