“…Breastfed children had higher muscle mass and lower fat mass and BMI than those who were not breastfed. The importance of breastfeeding was also observed in our previous studies (Pruszkowska‐Przybylska et al, ; Pruszkowska‐Przybylska, Sitek, et al, ).…”

“…The level of parental education was included as a widely known indicator of socioeconomic status (Currie, Elton, Todd, & Platt, ). Additionally, parental education seemed to be an important control factor in body composition and proportion investigations (Pruszkowska‐Przybylska et al, ; Pruszkowska‐Przybylska et al, ), and it was therefore applied in this investigation to authenticate the relation between body composition and proportion and vitamin D concentration. The level of parental education was categorized as: (a) basic or vocational education (8 years in obligatory primary school through 3 years in vocational school); (b) secondary education (4‐5 years in secondary school through bachelor degree, 3 years of education after secondary school); and (c) higher education (full university degree—master of science degree through doctorate).…”

Due to increasing problems with obesity and vitamin D deficiency among children, studies that tackle both problems together are needed. Methods: Data were collected from 182 randomly selected children aged 6-13 years in primary schools in central Poland. Measures included anthropometric dimensions, body composition, questionnaires completed by participants' parents, and saliva samples. The level of 25(OH)D was assessed from the saliva samples using an enzyme-linked immunosorbent assay kit. The children were divided into two groups: pre-pubertal (girls below 10 years and boys below 11 years) and pubertal individuals (girls above 10 years and boys above 11 years). Results: The 25(OH)D concentrations were higher in late spring (June) among pre-pubertal children than in the autumn (November-December) among pubertal children. The level of 25(OH)D was positively correlated with body cell mass (BCM,%) among all children (pubertal: R = 0.20, P = .044; prepubertal: R = 0.23, P = .041) and inversely associated with waist-to-hip ratio (WHR) among pubertal children of both sexes (R =-0.25; P = .031). The stepwise regression analysis revealed that investigation in spring (June) and breastfeeding was associated with increased muscle mass (MM, %) (beta = 0.253, P = .003 and beta = 0.225, P = .005, respectively) and total body water (TBW, %) (beta = 0.276, P = .004 and beta = 0.246, P = .011, respectively) and was associated with decreased body mass index (BMI; beta = −0.222, P = .024 and beta = −0.269, P = .009, respectively) and fat mass (%) (beta = −0.288, P = .003 and beta = −0.266, P = .005, respectively). Conclusions: Season of salivary sampling and breastfeeding status were more strongly associated with body components, BMI and WHR, than 25(OH)D concentrations.

“…Similarly, Wang et al (2019) [6] showed that individuals aged 2-6 years in South California (US) who were breastfed longer than 6 months had only slightly lower We also presented that maternal education and body birth weight may be an important factor for proper shaping BMI in later life. In other investigations which tackle the problem of maternal education impact on the offspring BMI the results were similar -the better educated mothers the lower BMI of their offspring [11,17,18]. In the case of birth body parameters we presumed that higher birth body weight is connected with higher BMI values in later stages of life, since 4-56 months of life to adulthood [11,13,14,19].…”

Objectives: Breastfeeding in the first years of life seems to be an important factor affecting the shaping the body mass, and body mass/height proportion during first months of life, that importantly differentiates body mass and body proportion at the later stages of the human ontogenesis. The aim of this study was to evaluate if duration of breastfeeding affects BMI in later life.Material: In the analysis 470 children born in time, aged 8-49 months were included. The data came from the nurseries in Lodz (central Poland) where children' parents filed the questionnaires and was collected in years 1993-1997. In the analysis were included information about: duration of breastfeeding, parental educational level, birth body weight, birth body length. The BMI was standardized on sex and age of the children. The stepwise regression models were used to evaluate the hypothesis. The obtained residues for BMI were used to verify only breastfeeding impact using the regression analysis.Results: The regression model included parental education level and birth parameters were used to adjust BMI on them and revealed that low educated mothers had children with higher BMI (Beta=0.213; p<0.015). Additionally heavier newborns had higher BMI at the later stages of ontogenesis (Beta=0.207; p<0.001). There were made two regression analyses using BMI residues. The first one treated breastfeeding as categories, and revealed that children breastfed over 6 months vs. not breastfed or breastfed no longer than 1 month had lower BMI (Beta=-0.098; p<0.030). The second model treated duration of breastfeeding as a continuous variable, and showed that breastfeeding duration was inversely correlated with BMI residues (Beta=-0.092; p=0.042).Conclusions: Duration of breastfeeding differentiates the BMI among Polish children aged 8-49 months and seems to reduce BMI in further life.Trial registration: This study was conducted according to the guidelines laid down in the Declaration of Helsinki and all procedures involving research study participants were approved retrospectively by the Ethical Commission at the University of Lodz (NR21/KBBN- UŁ/I/2018). Written informed consent was obtained from all subjects' parents.

“…Adicionalmente, estudios previos observaron una relación negativa entre la ratio 2D:4D y la masa muscular (Halil et al, 2013;Kociuba et al, 2018;Pruszkowska-Przybylska et al, 2018), que no fue obtenida en el presente estudio; a pesar de que, la testosterona ha sido relacionada positivamente con la producción de tejido muscular (Lin et al, 2012), y por tanto, una menor ratio implicaría una mayor cantidad de tejido muscular.…”
