The subjects were relatively fit, outgoing, and generally active but gained weight during the winter. Also, while their activity level decreased markedly during winter compared with that in summer, there was no seasonal difference noted in their nutritional intake. Concerning their daily schedule, hours spent on outdoor activities decreased and hours spent indoors increased during the winter. These results suggest that the increase in BMI during winter is caused by the decrease in the activity level. In health-promoting schemes for the elderly in snowy regions, an exercise program appropriate for winter, when the activity level decreases, is considered to be needed.
