  • Title: Are changes in body dimensions of adult females from Italy (Sardinia and Latium) related to secular trend?

    Abstract:
    This paper presents secular changes in height, weight, sitting height, relative sitting height, BMI and estimated lower limb length in two samples of Italian adult females from Sardinia (Cagliari) and Latium (Rieti). The samples consist of 579 healthy women from the province of Cagliari and 138 from the town of Rieti, aged 20.0-39.9 years, measured in the period 2003-2006. The women were divided into four 5-year age groups. The anthropometric variables were considered according to different socioeconomic status (SES) in the Cagliari sample, while the Rieti sample was considered as a whole, as the SES was homogeneous. ANOVA results suggest that the secular trend was very slow or had come to a halt in the Rieti sample but continues in the Cagliari sample, as shown by the statistically significant differences for estimated lower limb length (p<or=0.02), and relative sitting height (p<or=0.05). However, these differences disappear after ANCOVA with sibship size and socioeconomic status controlled for, suggesting that they depend mainly on the composition of the Cagliari sample in terms of SES. Therefore, it can be hypothesised that the secular trend might be very slow or has stopped in the Cagliari subsamples homogeneous for SES.
