Assessment of the BMI, WHR and W/Ht in pre- and postmenopausal women

Assessment of the BMI, WHR and W/Ht in pre- and postmenopausal women

The main goal of this study was to determine whether and how values of the BMI, WHR and W/Ht indicators change in pre- and postmenopausal women. The tested group consisted of 10,216 women aged 25-95 years. Data were collected during the national campaign "Fighting Obesity", organized by Hand-Prod Company between 2000-2002 across Poland, when adult women voluntarily filled in a questionnaire and participated in anthropometric measurements. The BMI, WHR and W/Ht values were calculated based on these measurements. The values of the BMI, WHR and W/Ht change with age. However, in each age group postmenopausal women have higher BMI, WHR and W/Ht than premenopausal women. Thus, the results obtained indicate that hormonal changes occurring in the climacterium period cause an increase in the analyzed index values. The BMI used herein is characterized by high accuracy in indicating obesity. Moreover, the WHR and W/Ht are also used as adiposity indicators, which may be useful in assessment of the risk of disease or death caused by hypertension, cardiac diseases, diabetes, or even cancers. However, they should not be used only in relation to obese women, because even a slight increase in visceral obesity, with body mass within normal limits, may contribute to unfavorable changes in the woman's metabolic profile, which in turn, may present a risk of illness.

Nutritional habits of female university students in relation to selfperception of body

Summary

Study aim: To determine whether the self-assessment of body mass has an impact on the nutritional behaviour of young women.

Material and methods: The material was gathered in cross-sectional research of 1129 female university students. The measurements of body height, body mass, and waist and hip circumference were taken. Each person completed a questionnaire concerned the nutritional habits, recreational physical activity, and self-perception of body mass. In this work, only the data of 925 students with BMI between 18.5 and 24.9 were included.

Results: Of the participants, 2.8% of the students assessed their body mass as too low, 75.4% as correct, and 21.8% as too high. Students assessing their body mass as too low featured the lowest values of BMI and waist circumference, whereas those with a body mass assessment of too high featured the highest values of BMI. Those students with a body mass assessment as too high followed a diet and skipped meals far more frequently, consumed breads and sweets far less frequently, and drank more liquids daily than students who assessed their body mass as correct. No differences were found in the frequency of recreational physical activity in relation to self-perception of body mass.

Conclusions: BMI values above population average, even if they fit within the norm, are regarded by the students as too high. The self-assessment of body mass as too high results in undertaking efforts aimed at reducing body mass.
