“…The RCT was rated as good quality, the case-control study was rated as poor quality, and the cross-sectional studies were generally of reasonable quality (see Appendix S3 in the Supporting Information online ). Tissue samples comprised bone (n = 4) (ie, rib, vertebrae, femur), 29 , 111 , 116 , 118 muscle (n = 4) (ie, diaphragm, abdominal wall, and gluteal area), 27 , 28 , 30 , 43 organs (n = 23) (ie, aorta, brain, eye, glands, gastrointestinal tract, heart, kidney, liver, lung, and skin), 28 , 40–46 , 108–115 , 117 , 119–122 and whole blood (n = 1). 71 Details of these studies are provided in Table S4 in the Supporting Information online , and the forest plot, including data from all ages, is presented in Figure S9 in the Supporting Information online .…”

“…On a whole-body basis, muscle and bone are two of the largest contributors to the total body zinc content in young children, yet findings showed a lack of new evidence reporting zinc concentrations in these tissues, Moreover, the evidence available came from a very small number of cadaver studies conducted between 1968 and 1984. 27–30 , 43 , 111 , 116 , 118 Zinc concentrations in muscle and bone were commonly reported per gram of dry weight and per gram of ash, respectively, requiring conversion to wet weight. If these conversions can be made based on assumptions of the water and organic content of the tissues, then an estimate of tissue accrual across the age range is required to arrive at the amount of zinc needed for growth.…”

Toward revising dietary zinc recommendations for children aged 0 to 3 years: a systematic review and meta-analysis of zinc absorption, excretion, and requirements for growth

Context The Food and Agriculture Organization of the United Nations and the World Health Organization are updating their dietary zinc recommendations for children aged 0 to 3 years. Objective The aim of this review was to retrieve and synthesize evidence regarding zinc needs for growth as well as zinc losses, absorption, and bioavailability from the diet. Data Sources MEDLINE, Embase, and Cochrane Library databases were searched electronically from inception to August 2020. Studies assessing the above factors in healthy children aged 0 to 9 years were included, with no limits on study design or language. Data Extraction Ninety-four studies reporting on zinc content in tissue (n = 27); zinc absorption (n = 47); factors affecting zinc bioavailability (n = 30); and endogenous zinc losses via urine, feces, or integument (n = 40) met the inclusion criteria. Four reviewers extracted data and two reviewers checked for accuracy. Data Analyses Studies were synthesized narratively, and meta-analyses of zinc losses and gains as well the subgroups of age, type of feeding, country’s income, and molar ratio of phytate to zinc were conducted. Meta-analysis revealed an overall mean (95%CI) urinary and endogenous fecal zinc excretion of 17.48 µg/kg/d (11.80–23.15; I2 = 94%) and 0.07 mg/kg/d (0.06–0.08; I2 = 82%), respectively, with a mean fractional zinc absorption of 26.75% (23.69–29.81; I2 = 99%). Subgrouping by age revealed differences in mean values associated with the transition from milk-based diets to solid food during the first 3 years of life. Conclusion This review synthesizes data that may be used to formulate zinc requirements in young children. Results should be interpreted with caution because of considerable heterogeneity in the evidence. Systematic Review Registration PROSPERO registration number CRD42020215236.

This study was undertaken to provide reference values of chemical element mass fractions in intact bone of Reference (European Caucasian) Man/Woman. The rib bone samples investigated were obtained from autopsies of 84 apparently healthy 15-58-year-old citizens (38 females and 46 males) of a non-industrial region in the Central European part of Russia who had suffered sudden death. The mass fractions (mg/kg given on a wet mass basis) of 69 elements in these bone samples were measured by using neutron activation analysis with high-resolution spectrometry of short-lived and long-lived radionuclides, particle-induced gamma-ray emission, inductively coupled plasma atomic emission spectrometry, and inductively coupled plasma mass spectrometry including necessary quality control measures. Using published and measured data, mass fraction values of the 79 elements for the rib bone have been derived. Based on accepted rib to skeleton mass fractions and reference values of skeleton mass for Reference Man, the elemental burdens in the skeleton were estimated. These results may provide a representative bases for establishing related reference values for the Russian Reference Man/Woman and for revising and adding current reference values for the International Commission on Radiological Protection. The data presented will also be very valuable for many other applications in radiation protection, radiotherapy radiation dosimetry, and other scientific fields.
