“…Since our study was focused on recovery one year postpartum, the impact of pregnancy on bone mass was not determined. In adolescent mothers followed up for a year postpartum, BMC and BMD loss and recovery follow a pattern similar to that observed in adult women (1,2,(20)(21)(22)(23)(24)(25) . To our knowledge, there are no papers reporting that BMC in lactating adolescents ,16 years of age is lower than that of 16-17-year-old adolescents due to the fact that the former may not be completely physiologically mature, as described in teenage pregnancies with respect to linear growth (47) .…”

Objective: Bone mineral density (BMD) loss has been described in adult women in the 12-month postpartum period. However, little is known about the precise BMD pattern in adolescent mothers. The present study aimed to evaluate BMD in Argentinean adolescent mothers followed up during the 12-month postpartum period. Design: Analytical, prospective clinical trial. BMD and body composition were determined by dual-energy X-ray absorptiometry; bone mineral content (BMC) and BMD were measured in the lumbar spine (L2-L4), femoral neck (FN), femur trochanter (TR), total hip (TH) and total body. Changes in BMD and BMC were analysed using ANOVA for pairwise comparisons. Other comparisons were performed with the paired-sample t test and Wilcoxon test; Pearson's correlation coefficient was used to analyse the relationship among continuous variables. Setting: La Plata, Argentina. Subjects: Adolescent mothers (n 35; 17 years old or less) were recruited within 15 d after delivery. Studies and follow-up were performed at 15 d and 3, 6 and 12 months postpartum. Results: BMD and BMC losses at 3 and 6 months and recovery at 12 months fitted a quadratic curve (ANOVA) at the three sites studied (FN, TH, TR), in total-body BMD (P 5 0?000) and BMC (P 5 0?038). At hip sites, BMD loss occurred at 3 months (FN, P 5 0?000; TR, P 5 0?000; TH, P 5 0?000) and 6 months (FN, P 5 0?000; TR, P 5 0?000; TH, P 5 0?000) compared with basal values. Percentage BMD loss immediately after delivery up to 6 months was about 5 %. Conclusions: Adolescents showed significant BMD and BMC losses at 6 months postpartum, with an almost total recovery at 12 months in all sites studied.

“…In spite of these low BMD values, fractures were not reported in the study subjects; however, poor bone health may predispose these women to osteoporosis and risk of fracture in later life. Longitudinal studies have reported improvement in spine BMD after weaning as compared to the postpartum period [3,29,30]; although our study design was cross-sectional, we also found higher values of BMD at 3 years compared to that at 1-week postpartum. These results remained unchanged even after adjustment for weight.…”

Background Bone turnover is high during lactation. However, studies on bone status of Indian urban mothers are scarce. Hence, the objective was to conduct a crosssectional study on the lactation-related changes in bone health status of Indian mothers postpartum using Dual X-ray Absorptiometry (DXA) at 3 time points: within a week of delivery, at 1-and 3-years postpartum. We also explored the association of dietary calcium intake, physical activity, serum vitamin D status, and dietary traditional food supplements (Dietary Food supplements) with bone health. Methods A cross-sectional study was conducted; 300 full-term, healthy primiparous women (28.6 ± 3.4 year) were randomly selected and categorized into 3 groups: 128 mothers within 7 days of delivery (Group A), 88 with 1-year-old children (B), and 84 with 3-year-old children (C). Anthropometry, lactation history, physical activity, diet, biochemical tests (vitamin D, parathyroid hormone), body composition, areal bone mineral density (a-BMD) at total body (TB), AP spine (APS), and dual neck femur (DF) were assessed by DXA (GE-Lunar DPX). Results Significantly higher APS-BMD (mean ± SD) was observed in Group C (1.107 ± 0.098 g/cm 2 ) than that in A (1.045 ± 0.131 g/cm 2 ) (p \ 0.05). When adjusted for breastfeeding practices, mean (±standard error) APS-BMD was lowest in women in Group A (1.024 ± 0.013 g/cm 2 ),

“…The effect of maternal calcium intake on infant growth remains unclear. Calcium intake during pregnancy may have a positive effect, but the research has provided conflicting results [16][17][18]. A positive relationship between maternal calcium intake and infant length or mid-upper arm circumference has been shown [17,18].…”

Background: Calcium deficiency is common in pregnant women and newborn infants. There are few data about the prevalence of calcium deficiency during pregnancy and infancy in Algeria. We assessed calcium status of pregnant women and their neonates in Sidi Bel Abbes, west of Algeria. The current study aimed to determine the prevalence of hypocalcemia in pregnancy and in their new born and to correlate maternal calcium status with neonates' calcium and birth weight.

Bone mineral changes during and after lactation

Abstract: A scheduled lactation period of 6 months, followed by a 1-month weaning period, allowed bone mineral density to reach higher values compared with early postpartum, regardless of calcium supplementation and duration of postpartum amenorrhea.
