Objective: Maternal anthropometry offers a rapid, inexpensive, and noninvasive method for assessing nutritional status during pregnancy. We aimed to assess the changes in maternal anthropometric measurements in the first month after delivery and to investigate the factors associated with longitudinal changes in maternal postpartum nutritional status.Design: This prospective longitudinal study included 147 mothers who were on the 5th postpartum day applied to outpatient clinics, from January 2018 through January 2020. Each mother completed a structured questionnaire and baseline anthropometric measurements were performed at the postpartum 5th day and re-evaluated at the end of the first month after delivery.Participants: Mother-infant pairs (n = 147). Results: At the end of the first postpartum month, maternal body weight (relative change −5.1%, 95% CI: −5.6%;−4.6%), muscle mass ratio (−1.6%, 95% CI: −2.4%;−0.9%) and body fluid ratio (−2.4%, 95% CI: −3.1%;−1.7%) decreased, whereas fat mass ratio increased (10.3%, 95% CI: 9.0%;11.6%).There was a significant association between infants' feeding type and maternal BMI, weight, muscle mass ratio, body fluid ratio, triceps, and biceps skinfold thickness in mothers (p < .05). We also found a significant relationship between maternal smoke exposure and BMI, maternal weight, fat-mass ratio (p < .05). Conclusions: There are some important alterations in maternal anthropometric parameters during the postpartum period. This study will help further our understanding of the factors influencing changes in maternal body composition after delivery.

Background. Mitochondrial uncoupling proteins (UCP) 1, 2 and 3 are members of the anion carrier protein family located in the inner mitochondrial membrane. There are various controversial reports on UCP genotypes and obesity in adults and children. This study aims to investigate the link between mostly studied UCP polymorphisms (UCP1-3826A/G, UCP2 Insertion/Deletion (Ins/Del) polymorphism of exon 8, and UCP3-55C/T Polymorphisms) and obesity in Turkish children. Furthermore, the relationships of UCP polymorphisms are also analyzed within the scope of metabolic parameters of obese children. Methods. Molecular screening of the UCP1, UCP2, and UCP3 gene polymorphisms was carried out in 189 children aged 6 to 18 years, 102 of who had exogenous obesity (54 girls) and 87 of whom were healthy controls (48 girls). In the obese group, fasting lipids, glucose and insulin levels were measured. In 60 obese children, an oral glucose tolerance test (OGTT) was performed with 0, 30, 60, 90 and 120 minutes of sampling for plasma glucose and insulin levels. Results. The frequency of UCP polymorphisms was similar in obese and non-obese children. In obese children, fasting lipids, glucose and insulin levels were not different among the UCP 1, 2 and 3 genotypes. While no relationship was found between the UCP 1 and 3 genotypes and glucose/insulin levels during OGTT, carriers of the Insertion allele with UCP2 Ins/Del polymorphism had significantly higher 30-minute insulin levels (p=0.018). Conclusions. Polymorphisms of the UCP1-3826A/G, UCP2 Ins/Del, and UCP3-55C/T are not associated with obesity and related pathologies in Turkish children. However, the presence of the Ins allele of the UCP2 gene has been found to have an unfavorable influence on early insulin excursion after glucose loading.
