A questionnaire was conducted on the living and working conditions of inhabitants in the suburbs of a city in Hiroshima Prefecture. Respondents received medical and nutritional examinations. A summary of our findings is as follows:
Those persons who are apparently overworking themselves eke out their energy deficiency by taking diets rich in carbohydrate complex. Their major health problems are hypertension, ischemic changes in ECG, anemia and lower cholinesterase activity.
There were indications that agricultural chemicals have harmful effects on the health of the examinees.
In contrast, many of those who work less consume large-even excessive-amounts of animal proteins and fats. Among them prevail liver failxure and metabolic disorders.
In either group of the people examined, there was amundant evidence to show that they are at risk of developing arteriosclerosis.
These findings should be taken into consideration when a health control program is implemnted.

Epidemiological investigations were made on carcinoembryonic antigen (CEA) levels in 3, 259 rural inhabitants and 3, 200 urban inhabitants. Abonormally high CEA levels were found in 12.0% of male rural inhabitants and 6.8% of male urban inhabitants. For women, the percentage was 2.4% in rural areas and 1.6% in urban areas. Correlations between high CEA levels and age were noted in men. However, cigarette smokers had higher CEA levels than non-smokers in both rural and urban areas irrespective of age. Smokers' CEA levels were higher rural areas than in urban areas. These disparites in CEA levels between rural and urban inhabitants were studied, but remain unaccounted for.
