This report continued from the last report, Part II, assuming a side view of working hours, is an investigation on the effect of dietary life of two hundred married women on day duty with two weekly holidays working at the Monopoly Corporation Fukuoka Factory. 1) The housewives of the single type families spend about three hours in performing domestic affairs on week days. This is the average time spent in the case of the housewives on duty. 2) On weekly holidays they spend two or three times more time than week days in domestic affairs, but the increase in hours spent for preparing meals is small. 3) The housewives who have co-workers can shorten the hours spent for domestic affairs on weekdays by thirty minutes. 4) If the housewives are on day duty and as in the case of employees of public corporations, their working conditions are stable, so time to take supper, to go to bed is neither so late nor irregular; the percentage of those taking breakfast is good, and their daily life is regular.
For the purpose to study the diet, salt intake, growth, blood pressure of a protective institutionchildren, 31 children (M 18, F 13) of 16 to 27 months old admitted in an institution were followed up for one year from April, 1975 to March, 1976. The results obtained are as follows: (1) The average height of the boys was 0.6cm lower than that of Japanese standard children at the beginning of this study, and it reached 1.2cm above that after one year. The height of the girls exceeded 0.6cm the standard at the beginning, but the difference was estimated 2.2cm at the end. (2) The average weight of the boys which was about the same level as the standard at the beginning exceeded 0.5kg the standard at the end. The weight of the girls exceeding 0.4kg the standard at the beginning was 1.25kg over that after one year. (3) The average Kaup index remained in the 16's throughout the study period. (4) The supplies of total energy, protein, lipid, and calcium throughout 12 months were 1197±42.9Cal., 47.2±1.3g, 31.4±2.0g, 637±29.3mg, respectively. The protein and calcium supplies were about 10g and 200mg more than the Japanese recommended dietary allowances, respectively. (5) The energy and protein supply per kg body weight of both sexes were 97Cal. and 3.8g, respectively. (6) The frequency of leftover meals was about 2 times per month per child in both sexes, though it increased to 7-8 times per child during the period of smallpox prevalence in July. (7) There was a negative correlation between the frequency of leftover meals and weight gain.
