Food iron absorption in iron deficiency.

The absorption of food iron in relation to the diet was studied in 10 phlebotomized normal young male subjects during 3 to 5 months. The iron absorption was calculated from the net increase of the hemoglobin mass. There was pronounced individual variation in the mean dietary absorption ranging between 1.9 and 5.0 mg. There was no correlation between the amount of iron absorbed and the amount of iron ingested. There was no apparent influence of a high or a low intake of animal products, cereals, vegetables, tea, or alcohol on the individual absorption values. A negative correlation between the iron absorption and the total amount of fecal dry substance was observed. This might be ascribed to an influence of dietary fibers on the absorption of food iron.

The population study of women in Göteborg 1974--1975--the second phase of a longitudinal study. General design, purpose and sampling results.

A study of a population sample of women in Göteborg aged 38--60 years was carried out in 1968--1969. This population sample has been re-studied during the years 1974--1975. Altogether 1302 women participated in this second study, which means 89.1% of those studied in 1968--1969 and 80.3% of those initially sampled. Twenty-six women had died during the interval between the two studies, more than half of them from neoplastic disease. Information is given about those who had moved or were inaccessible at the time of the second study or who refused to participate. The performance of the examination is described and research projects are outlined.

Body water and weight in patients with premenstrual tension.

The total body water, total body potassium and weight were studied during the follicular and luteal phases of the cycle in 20 patients with severe premenstrual tension and 20 controls without symptoms. The effects of a diuretic (bumetanide) and bromocriptine were also studied in the patients with premenstrual tension. The mean body water in the premenstrual tension group did not differ significantly from that in the controls neither did the mean body potassium levels. However, during the late luteal phase the water/potassium ratio in liters per mol of potassium was significantly higher in the patients with premenstrual tension than in the controls. In the women with premenstrual tension the body water values varied more widely between the luteal phase and follicular phase than in the controls. The mean body water and weight in the premenstrual tension group were similar in the late luteal and early follicular phases. Treatment with bumetanide or bromocriptine had no effect on the parameters studied.

The study of women in Gothenburg 1968-1969. Intake of energy and nutrients in five age groups.

Women from five age groups (38, 46, 50, 54, and 60 years), participating in the population study "Women in Gothenburg 1968-1969", were subjected to a 24-hour recall dietary interview (n = 1361). In a randomized subsample (n = 418), a dietary history was obtained and individuals in another randomized subsample (n = 755) submitted a 24-hour urine specimen for nitrogen analyses. There were significant differences between the 24-hour recall and dietary history figures in all five age groups with respect to energy and all nutrients. The mean protein intake calculated indirectly from the urinary nitrogen excretion came close to the figures calculated from the dietary histories in four out of five age groups. The energy intake and, consequently, the intake of most nutrients calculated from the dietary histories were higher than generally ascribed to Swedish women, as most previous data have been obtained by 24-hour dietary recall interviews. Most women (71-89% in the different age groups) consumed too much fat and most women of fertile age (80-92%) consumed too little iron. A significant decrease in the mean energy intake was apparent only in the age group 60, i.e. 1870 kcal versus 1965--2 105 in the other groups.
