[Iron deficiency and anemia in professional working women]. / Niedobór zelaza i niedokrwistosc u kobiet zawodowo czynnych.

The hematological indices (Hb, Ht, MCHC) and iron status (serum iron, TIBC, LIBC, transferrin saturation), the prevalence of iron deficiency anemia in 224 women aged 31 to 47 years, working in textile industry in Lódz were examined. Nutritional status was evaluated as follow: body height and weight, body mass index (BMI kg/m2) and body fat content (%) calculated from the four skinfolds sum. Anemia (Hb < 12 g/dl) was stated in 11.2% participating women, evident iron deficiency (Fes < 60 micrograms/dl, Sat % < 16) in 13.4% of population. The positive correlation was found among hematological indices and body weight, body mass index and body fat content and relationships among iron status indices (Fes mu/dl, Sat%-positive correlation; TIBC microgram/dl, LIBC microgram/dl-negative relationship) and body fat content (%). The prevalence of iron deficiency and anemia were lower than in other women population in Poland examined in 1974-1986. The relationships among energy and protein nutrition and iron status and iron deficiency anemia suggest, that the menstruating overweight women or with obesity may be the group with lower risk of iron deficiency anemia.

[Nutritional assessment of women working in the textile industry in Lodz from 1986 to 1989]. / Ocena wyzywienia kobiet pracujacych w przemysle wlókienniczym w Lodzi w latach 1986-1989.

This communication was designed to determine the intake of food products and nutrients in randomly selected manual workers (women) of the textile industry, as well as to quantitatively evaluate the deficiency or excess of nutrients in their average diet. Daily nutrition was evaluated in 300 females, manual workers aged 35-44 years. Rheir nutrition was assessed by the method of a questionnaire concerning food intake during 24 h prior to the inquiry. As a result, the kind of nutrition was determined. Moreover, the nutritive value of the daily food rations, as well as the intake of the different groups of food products were calculated and compared with the recommended food standard B. The results indicate that: the observed unbalanced nutrition involving deficiencies of milk, vegetables, fruits and cereals may lead to e.g. disturbances in the acid-base equilibrium and to hypovitaminoses; the deficiency of magnesium and calcium creates the risk at the accelerating sclerotic changes; deficiencies of iron, zinc and cooper in the diet of women of reproductive age may result in the occurrence of anemia and exert an adverse effect on the offspring; on account of work in two or three shifts, it is indispensable to organize taking of meals during working hours.

Protein utilization in rats receiving a low-protein diet with various limiting amino acids.

1. A study was made of protein utilization in rats given a variety of low-protein diets containing (g/kg) egg albumin 18, casein 49, gluten 50, or mixtures of either maize protein and gelatine 58, or casein and gelatin 37, each with supplemental methionine. The diets were limiting in leucine, tryptophan or lysine, or in both tryptophan and the sulphur-containing amino acids. 2. Values obtained for net protein utilization (NPU) at these low levels of nitrogen intake were markedly higher than the amino acid score calculated for the different test proteins, except with casein for which the two values were similar. The NPU values agreed more closely with chemical score values based on the content of S-amino acids or isoleucine in the dietary protein.
