Correlation of spouses’ body weight (results of a 15-year prospective study)

Aim. To study the cross-sectional prevalence of overweight (OW) in men and women, in regard to their spouses’ body weight (BW), as well as to assess the BW dynamics in participants and their spouses over 15 years of the prospective follow-up. Material and methods. In the screening study, body mass index (BMI) was assessed in 425 married couples. The repeat assessment, performed 15 years later, included 232 couples who were still married. OW was diagnosed in subjects with BMI ≥25 kg/m2. Results. In the wives of OW men, OW prevalence was higher (76,2%) than in the spouses of non-OW men (61,3%; p<0,001). In the husbands of OW women, OW prevalence was also higher (61,3%) than in the spouses of non-OW women (43,8%; p<0,001). In the prospective study, the participants with no OW at baseline, whose spouses developed OW, the incidence of OW was significantly higher (60,9%) than in participants whose spouses remained non-OW (16,4%; p<0,001), or in participants whose spouses remained OW (31,7%; p<0,05). Among men and women with OW at baseline, whose spouses reduced their BW and became non-OW, BW normalization was more frequent (32,0%) than in the participants whose spouses either remained OW (9,1%; p<0,001), or remained nonOW (3,4%; p<0,001), or increased BW and became OW (6,9%; p<0,05). Conclusion. BW dynamics in spouses was characterized by parallel increases or decreases, due to shared social and intra-familial factors

Body mass, marital status, and number of children in the family

Aim. To study the effects of social factors (marital status, the number of children born and raised in the family) on the incidence of body weight (BW) increase. Material and methods. The 15-year follow-up focussed on BW dynamics in men and women, in regard to the changes in their martial status. At baseline, all participants were married (n=845; 327 men and 518 women). To evaluate the effects of the children’s number on increased BW incidence, 238 women aged 40—59 years and having at least one child before the baseline, were examined (≥ 2 children in 163 women, 1 child in 75 women). Increased BW was registered if body mass index (BMI) was 25 kg/m2 or higher. Results. In widowed participants, the incidence of BW increase was lower (1,9 %) than in those married (10,5 %; p<0,01) or divorced (21,4 %; p<0,01). In widowed women, the normalisation of initially increased BW was registered more often (13,5 %), compared to their still married peers (4,3 %; p<0,05). In those still married, BMI increased from 26,95±0,09 to 27,91±0,09 kg/m2 (p<0,001), while in those widowed, it decreased from 29,92±0,24 to 29,34±0,24 kg/m2 (p<0,05). In women with 2 or more children, the incidence of BW increase was higher (85,3 %) than in women with only one child (73,3 %; p<0,05). Conclusion. The change in marital status could affect BW dynamics. Spouse death is an important cause of BW reduction. In women with 2 or more children, increased BW was more common than in women with only one child

GNU Radio

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems
