Item Biological fitness at middle-age is reduced in both very lean and obese males(Polskie Towarzystwo Antropologiczne, 2003) Lipowicz, AnnaIt is well-documented fact that the relationship between body weight and premature mortality is not linear. Very often it is described as J- or U-shaped. There is solid evidence for strong relationships in adults between obesity (as defined by high values of the body mass index, BMI), mortality, hypertension, cardiovascular disease, stroke, and non-insulin dependent diabetes. However, the opposite end of the BMI distribution (leanness) remains an area of controversy among European populations. Many authors have indicated that leanness elevates the risk of premature mortality, although to a lesse degree than obesity. The aim of this sudy is to examine whether abnormalities in blood pressure and lung function occur more frequently at both extremes of the BMI distribution than in its middle range.Item Fatness of children and adolescents from various socio-economic groups between 1978 and 1988(Polskie Towarzystwo Antropologiczne, 1999) Lipowicz, AnnaThe study material contains the data on boys and girls aged from 6 to 18 years located in the course of the Third and Fourth Anthropological Surveys carried out in Poland in 1977/78 and 1987/88. The questionnaire data (father's and mother's education and number of children in the family) were supplemented with the results of measurements of the triceps skinfold. It is assumed that the triceps skinfold is a good indicator of the nutritional status. In both studies fatness of children decreased along with a decreasing level of parents' education and with increasing family size. Triceps skinfold size was related mainly to the number of children in the family. In the decade from 1978 to 1988 a decline in social differences with regard to fatness of children coming from various socio-economic strata was observed.Item Marital status and biological conition of Polish males(Polskie Towarzystwo Antropologiczne, 2001) Lipowicz, AnnaStrong evidence for marital differences in mortality has been demonstrated in a large number of countries. Married men and women have lower death rates than unmarried individuals within each adult age group. Additionally, married persons tend to be healthier as compared to unmarried. In the literature two explanations for this patterning have been proposed. "The health selection hypothesis" seggested that disabled or less healthy people are not as likely to get married as the healthy ones. In "the social causation hypothesis", marriage yields health benefits through emotional and social suport which may act as a buffer against the effects of life stress. In this study, "the social causation hypothesis" is supported.
