In view of the present situation of agriculture in which housewives have to handlethe bulk of farm work, a study was made on the health conditions of women engaged in farming in comparison with those of non-farmers.
The study covered a total of 28, 600 females, aged from 40 to 59, who received masshealth screenings conducted between 1978 and 1980 on rural inhabitants in Nagano Prefecture as part of the outreach program by the health service corps of our hospital.
All the examinees live in areas whose principal crops are rice, vegetables and/or fruits.
The data were arranged according to seasons based on the dates of health examination in order to clarify the seasonal variations of morbidity rates and other indices of health.
Another investigation was made into seasonal changes in the length of time used byhousewives in farming, domestic chores, rest and so on with a view to studying correlation between the mode of living and health conditions.
To sum up, our findings are as fllows:
(1) Seasonal variations in the results of various laboratory tests and morbidity rates were notable, depending on the amount of farm work, dietary habits, coldness and the height above sea level.
(2) During summer months, the incidence of anemia was exceedingly high, obesity rates plummeted, and serum cholinesterase values dropped sharply among housewives who are engaged in farm work, compared with those who are not.
(3) In summer, farm housewives worked long hours in the fields, slept less and rested less. They had not enough time to attend to household duties.
