Serum Zinc, Copper, and Zinc/Copper in Healthy Residents of Jinan

Abstract

Sera of 890 healthy Jinan residents were chosen randomly, and the concentrations of serum Zn and Cu were detected by atomic absorption spectrometry. The mean serum Zn and Cu concentrations and Zn/Cu were 1.32 +/- 0.49 mg/l, 0.99 +/- 0.26 mg/l, and 1.41 +/- 0.56, respectively. Significantly higher levels of serum Zn and Zn/Cu but lower serum Cu were found in the men. Descending tendency of serum Zn and Zn/Cu was observed with social-economic status and age but not significant. Alcohol consumption produced higher level of serum Zn and Zn/Cu but lower Cu concentration. Smoking caused significant lower level in serum Cu concentration but no significance in serum Zn and Zn/Cu. Serum Zn and Zn/Cu were normal only when hours of sleep a night were kept within 7-9 h. Higher level of serum Zn and Cu concentrations and Zn/Cu were observed in individuals with regular physical exercise, but still no significant difference existed. No clear relationship between educational levels with serum Zn and Cu concentrations and Zn/Cu was observed.

Serum copper, zinc and high-sensitivity C-reactive protein in short and long sleep duration in ageing men

“…Our observations concerning the correlations between sleeping hours and both the S-Zn levels and the Zn/Cu ratio are in line with previous studies in smaller and mixed gender samples [3,4]. In contrast to earlier knowledge, we observed highest average levels of S-Cu in the category for the longest sleep duration.…”

“…The study population was substantially larger compared with previous studies focusing on sleep and micronutrients [3,4]. We were able to evaluate the role of potential confounders such as depressive symptoms, which relate to sleep duration as well as serum levels of Zn, Cu and hs-CRP [15].…”

“…The levels of serum Zn and Zn/Cu ratio have been suggested to have positive correlation with sleeping hours, whereas increased serum Cu levels are associated with decreased sleep [3,4]. Altered sleep duration (e.g.…”

Serum Copper and Zinc Levels Among Iranian Colorectal Cancer Patients

“…The altered levels of serum trace elements may be attributed to a few reasons such as the unbalanced dietary intake, adverse effects of drugs, decreased gastrointestinal absorption, changes in the level of the related plasma metal binding proteins, and an enhanced sequestration in the tumor tissue [31,32]. The association between socioeconomic factors and serum concentration of Cu and Zn has been demonstrated in a number of previous studies [33,34]. Due to incomplete information collected from our subjects, we were unable to evaluate the effect of dietary intake and socioeconomic factors on serum Cu and Zn contents in our study groups.…”

Copper Concentration in a Healthy Urban Adult Population of Southern Iran

“…The mean concentration for copper in this study was similar to figures for Greece and Northern Ireland and but higher than in Germany, Norway, continental Spain, the Canary Islands (Spain), Oman, China, and India. However, compared with the high value reported for Kuwait, mean serum copper in all adult Iranian populations was lower [15][16][17][18][19][20][21][22][23][24]. This difference could be due to local or regional differences in nutritional habits.…”
